Anders Ardoe has a background in Computer Systems with a Ph.D. 1986 from Lund University. He has been working with networked computers since 1980 and during 1986 - 1994 as Ass. Professor in Computer Engineering at Lund University. The last years he has been involved in introducing the concept of networked information in libraries. Since 1992 he is working with developing electronic library services first at Lund University Library, Development Department (LUB NetLab) were he was department head from 1994 - 1996. From 1996 he is head of development at the Technical Knowledge Center & Library of Denmark. The European Union projects he is currently involved in are: DESIRE II, UNIverse, GAIA and EULER. (See statement with Traugott Koch).


Vasil Babamov is the Editor of the Chemical Abstracts Thesaurus.  He oversees the development of the Thesaurus, which currently has about 15,000 preferred terms, and its integration into the building of the CA database.  A particularly concern is the implications that the expanded networked applications of thesauri will have on the development of the thesaurus structure and content to ensure that the thesaurus remains a useful tool for purposes beyond its traditional implementation.  Another concern is with providing networked thesaurus access to the analysts involved in building the database and maximizing the benefits of using the thesaurus in the database building process.  The CA Thesaurus is presently fully accessible only internally: on STN via the existing STN thesaurus software; via an Intranet web-based hypertext thesaurus tool; and via a couple of internally developed tools that partially integrate the thesaurus into the database building process.  We are anticipating incorporating the thesaurus into the public access to the CA database on STN, the web-based STN-easy and Scifinder that provide access to multiple databases, and into other planned CAS products. Additional work needs to be done on the thesaurus to enable automatic backfile search in light of the major changes our vocabulary has undergone. The only public assess to the thesaurus is a restricted version of the internal web thesaurus hypertext tool that provides only a listing of the thesaurus terms. This listing can be accessed at: .  Dr. Babamov received a Ph.D. in Chemical Physics from the University of Illinois in 1977 and was engaged in research and teaching in that field at several universities before joining Chemical Abstracts as a Scientific Information Analyst in 1986.


Bruce Bargmeyer is a Computer Scientist at the U.S. Environmental Protection Agency and Guest Researcher at the National Institute of Standards and Technology.  Bruce is chair of the ISO/IEC JTC 1/SC 32 (Data Management and Interchange) and vice chair of the NCITS L8 group for Data Representation. Bruce is interested in the use of metadata registries for knowledge organization services. Current operational and research work involves the Environmental Data Registry, the EPA Terminology Reference System  and the Environmental Data Exchange Network (EDEN). EDEN is a collaborative effort between the European Environment Agency, the Environmental Protection Agency, the US Department of Defense and the US Department of Energy. It involves work on standardizing metadata and includes a demonstration of the use of an ontology for querying widely distributed databases using request brokers, agents, mediators, and related intelligent information services technology. (added 8/17/99)


Laura M. Bartolo is an Associate Professor in Libraries and Media Services at Kent State University. Her primary focus in the ALCOM/NIST Heterogeneous Structures Project is network-accessible information description and retrieval. Specific groups of terms in related areas have been developed among the scientists with the growth of the Liquid Crystalline Optical Materials (ALCOM) subject domain. A next step in the project is to develop a knowledge organization structure related to liquid crystal research building upon the thesaurus and classification tools in place.  The knowledge structure will incorporate the multiple domains represented within the project, the interests and needs of applied and basic research, and will capitalize on distributed information services.


Sean Bechhofer is a Research Fellow in the Information Management Group at the University of Manchester. He received a B.Sc. degree in Mathematics from Bristol University in 1988 and has been a researcher in the University of Manchester Department of Computer Science since 1993, working initially with the Medical Informatics Group on the GALEN project ( His main research interests are in the applications of description logics, particularly as a delivery mechanism for terminologies and semantic metadata, and their use in indexing and retrieval. He is currently involved with the STARCH ( and TAMBIS ( projects. STARCH is concerned with using DL models to support querying over picture archives, while TAMBIS uses a conceptual model to provide unified access to multiple biological information sources. [added 11/20/98]


Denise A. D. Bedford is currently Thesaurus Manager/Developer for The World Bank in Washington, DC.   She is responsible for the development of the forthcoming 1998 edition of The World Bank Group's Thesaurus.  The Thesaurus takes the form of electronic and print editions, as well as serving as the intelligence behind the "smart" RetrievalWare search engine. She has earned Ph.D. (Information Science, UC Berkeley), MS (Librarianship, Western Michigan University), MA and BA (Russian;  German;  History, University of Michigan).  Other employment highlights include:   Catholic University of America (Adjunct Faculty), Intel Corporation, NASA GSFC and STI Program, Stanford University, University of California Systemwide Administration, University of Michigan, as well as consulting projects for International Monetary Fund, and federal agencies.

Objectives for the workshop:   (1) learn which of the NISO-defined thesaurus relationships other organizations and researchers are using in mapping thesaurus content to semantic network structures, as well as relationships in use beyond this set;  (2) determine whether there is practical consistency in the naming conventions for semantic relationships, and (3) learn how other organizations have "packaged" semantic network relationships to search strategies for end-users.


Anne Betz graduated in Library and Information Studies at the University of Applied Sciences in Cologne, Germany, Department of Library and Information Studies (LIS), in September 1997. From October 1997 on she is working half-time at DEUTERM, the recently founded German Information and Documentation Centre for Terminology. DEUTERM is to represent the German node in a European Terminology Documentation Centre Network (TDC-net) being established in the course of a European Union project which started in August this year. The TDC-net Project is an activity within the framework of the European MLIS Programme (MultiLingual Information Society).

"In general, my interest in the NKOS initiative is exchanging professional information on a high level and learning more about the methodical and technical aspects of realizing multilingual access to databases and Web sites by means of controlled vocabulary systems.  As DEUTERM offers a list of thesauri, thesaurus maintenance software and classification schedules browsable by languages and by subject ( which is to be represented by means of systematic categories one day, I am especially interested in the discussion about and the development of the Thesaurus Registry."  (added 10/23/98)

Stan Blum is the Research Information Manager at the California Academy of Sciences, San Francisco. By academic training he is a systematic ichthyologist (the classification of fishes; Ph.D. Zoology, University of Hawaii, 1988). Since 1990, however, he has been working full-time in biodiversity and natural history collections informatics. The two most important themes in his work have been: 1) designing integrated information systems for natural history museums (i.e., systems that support a wide variety of collection disciplines, collection management practices, and uses of collection information), and 2) developing data standards and software architectures that will enable data to be integrated across distributed and heterogeneous collection databases. He recently organized "A Workshop on the Compilation, Maintenance, and Dissemination of Taxonomic Authority Files." The purpose of the workshop was to provide an initial forum for members of the systematics and library/information science communities to discuss concepts, practices, and technologies that will promote consistency in the cataloging, indexing, and retrieval of biological information. Workshop results indicated that biological taxonomy and classification would provide a challenging test bed for cross-discipline work involving thesaurus development, authority control, cooperative cataloging, and multi-thesaurus integration. Participants recommended that the dialog between the communities continue, particularly under the framework of DL research. (Added 8/3/98; updated 3/4/99.)

Martin Doerr is a Senior Application Scientist with the Centre for Cultural Informatics and Documentation Systems, Institute of Computer Science, Foundation for Research and Technology, Hellas (FORTH), Heraklion, Crete, Greece. He works on thesaurus management, ontologies and heterogeneous data access in close cooperation with cultural bodies and library organisations.

"Based on my experience from classification methods in software repositories, and with semantic network-based cultural documentation systems, I have led the development of a proof-of-concept prototype for a new vocabulary management system for the Getty Information Institute (former AHIP) in Los Angeles. This system demonstrated the capability of the Semantic Index System, product of ICS-FORTH, to manage effectively amounts of hundreds of thousands of terminological records in various schemata. With the AQUARELLE project as test bed, we have developed this prototype into a competitive thesaurus management system for multilingual thesauri, the "SIS-TMS". Its novel features is a partitioning and versioning mechanism, which allows for consistent cooperative development by semi-autonomous groups and integration of distributed "terminology servers" into heterogeneous
information environments. It is on product level since summer 1998, and has already found vivid interest in Greece, France, England, and Italy and at the European Commission.

"Recently, I have initiated and participate in the European Term-IT project in the Language Engineering Sector of TELEMATICS, which aims at combining language engineering and human processes for the more efficient production of terminological resources in the cultural domain. My interest in thesauri is complementary to my work on conceptual structures with respect to the general problem of information mediation in heterogenuous distributed environments. I do research and have published on questions of knowledge representation, cooperative development of thesauri and knowledge resources, effective information access and architectures for heterogeneous distributed information environments.

"I am member of ICOM-CIDOC and involved in the development of a domain ontology for the museums community, the oo CIDOC Reference Model, going to be presented in October in Melbourne." (added 9/9/98)

Stuart Gagnon, Internet Librarian for Terminology Projects, works as a contractor with GCI Information Services for the U.S. Environmental Protection Agency (EPA) at the EPA Headquarters Information Resources Center.  A graduate of UNC-CH School of Information and Library Science (SILS), he has worked in libraries and/or with databases for over 5 years.  He recently supported development efforts for an EPA metadata catalog which will provide enhanced access to the Agency's Web resources.  [This metadata catalog is currently in an Intranet production phase.]  Mr. Gagnon leads a small team of  Internet librarians who support the work of EPA's Enterprise Information Management Division (EIMD) in their efforts to assist the European Environment Agency (EEA) in upgrading their thesaurus product, GEneral Multilingual Environment Thesaurus (GEMET).   He also leads the team's efforts on a collaborative project between EIMD and the EPA Superfund Information Management Center (IMC) which would integrate a coordinated electronic tool in which related information, including data, subject terminology and metadata, will be collected and shared between many systems, across the Web.  State-level agencies that collect hazardous waste clean-up (Superfund-related) data will be invited to participate in this project that is designed to enhance the collection of similar data, help in the building of new databases and drive search engines.  The project includes a working component that would allow users to query disparate legacy databases in a networked environment.  Components of this project are: the Environmental Data Exchange Network (EDEN), the Environmental Data Registry (EDR) and the Terminology Reference System (TRS).  This project espouses a 'registry' approach
to standardization. [added 4/9/99]


Ecaterina Geber is carrying out research in the area of Intellectual Access to Cultural Information at CHIN. Her work at ARTEXPO Foundation and the Information Center for Culture and Heritage Romania, for over 15 years, focused on three main areas: definition of communication and information sharing procedures, data modeling and development of standards, access to and integration of resources in a distributed multicultural environment. Ecaterina was responsible for the design implementation, administration and evolution of the Romanian National Cultural Heritage Information System from over 300 cultural institutions in Romania. Ecaterina initiated and managed the development of a series of CD-ROMs and imaging projects focusing on cultural topics.

The launch of ARTEFACTS CANADA in April, 1998 by the Canadian Heritage Information Network (CHIN) signaled the first step towards integrated access to information about objects held in Canadian museum collections. Artefacts Canada, formerly the National Inventories, is the product of decades of collaboration between the Canadian museum community and CHIN, and contains millions of records describing objects, natural science specimens and archaeological sites. Effective access into an information environment containing a diversity of resources and over twenty million of information items strongly revealed the necessity of terminology and classification tools to support both description and retrieval.

The integration of The Art & Architecture Thesaurus with Artefacts Canada is one of the most significant improvements to access and retrieval. The thesaurus, used as a behind-the-scenes retrieval tool, enables access to objects through hierarchies. This integration has permitted a conceptual structure, that embeds art history knowledge, to be applied to the terminology used in the existing information collections, without the need to modify the resource itself or to impose vocabulary or category structures on those participating in the building of this collective resource. The architecture enables the potential addition of other authorities and organized information resources, including geographical or temporal perspectives, or offering alternative views for search results categorization.

To enable access in both French and English, a multilingual thesaurus was developed using The Art & Architecture Thesaurus as a base. The most frequently used terms in the Humanities database were identified and a French equivalent term was defined. Currently, there are 2,600 French terms available and active during the retrieval process.


Carole Goble  is affiliated with the University of Manchester U.K. Her work over the last eight years has been in clinical technologies and controlled vocabularies and in the last two years on terminologies for works of art. They use Descriptor Logics and terminological reasoning to build self-organizing compositional schemes. She is just starting to work on a funded project in collaboration with the Getty Images to classify the subjects of the Hulton-Getty Picture Archive.


Joel Hammond is in the Abstracting and Indexing Department for BIOSIS. He was instrumental in the design of the new BIOSIS relational indexing system.


Quinn Hart is a Technical Researcher for the California Resources Agency's CERES Program, the California Environmental Resources Evaluation System.  Quinn is responsible for review and implementation of standards and applications relating to metadata, indexing, and cataloging issues. CERES' thesaurus project  is part of an effort to standardize the language used when indexing, and searching for environmental data products in California.  In addition to the generation of a thesaurus of environmental terms, CERES is developing a toolkit that will allow for distributed access to thesauri in a consistent manner for application development.  This toolkit is based on an object-oriented paradigm, abstracting a thesaurus into a set of objects and methods. A toolkit in PERL has been developed and one for JAVA is underway.

Linda L. Hill is a Research Specialist with the Alexandria Digital Library Project at the University of California, Santa Barbara. She has worked extensively with thesaurus and metadata development and digital library projects. She has worked extensively with gazetteer design and implementation as interactive digital library services. Part of the gazetteer work has included the development of a Thesaurus of Feature Types.

"My personal goal in relation to this workshop is to get thesaurus principles and practices enabled within digital libraries so that existing thesauri can be more known and accessible, so that developing projects will recognize the value of the thesaurus approach and will develop and use thesauri according to established standards. Also, to evaluate the usefulness of thesauri and classification systems for networked information discovery."

Gail Hodge, Information International Associates (IIa), has been involved with production systems for abstracting/indexing services for 20 years. She's currently working as a consultant to USGS on a biodiversity vocabulary for the National Biological Information Infrastructure (NBII). She previously held positions with the NASA Center for AeroSpace Information and with Biosis.

"My main goal is to promote this discussion at a high level so that what we do within the U.S. Geological Survey, Biological Resources Division (BRD) context is based on where we are within the technical community. We know that we can't wait until all the problems are solved, but we want to be in synch as much as possible. We need an understanding of the issues involved in using distributed thesauri: How do we handle rights management, authentication, etc. and charging for commercial databases? What will users want to do with these distributed thesauri?  This effects navigation, searching, "transfer," etc. What do we need to know about other thesauri and vocabularies in order to use them in a distributed fashion? Is a registry both of thesaurus elements and of particular thesauri necessary to this effort? Where does this effort intersect with the efforts of others: RDF, XML, metadata schema, metadata registries, Z39.19, Z39.50, search engine vendors, etc.? I would like to come out of this with at least a start toward a way to deal with the architecture so that we can move forward and integrate this effort with other metadata and Internet efforts."

Paul Hower is with Intermedia Marketing & Production, Inc. in Atlanta. He says: "My first brush with information science was when I took courses at the UC Berkeley School of Library and Information Studies in 1977. After turning down a generous offer by Dr. Maron to stay at Berkeley, I went on to get a Masters degree in something called "Interactive Telecommunications" at NYU. The philosophy of that program was to provide students with the requisite tools and knowledge to understand all aspects of interactive services, from the technical and social to the legal and economic. This background has served me well as an IT consultant, corporate manager and in my own businesses.

I have enjoyed something of a retirement for the past few years, but have continued to consult at the request of associates and referrals. IMP's latest client is Consumers Union - the non-profit publisher of Consumer Reports - who hired us to help them understand "post Web site" Internet opportunities. We are urging them to keep an eye on developments affecting the "semantic interoperability" of the Internet, and have described how metadata, vocabulary control and personal 'bots' may change the way people shop over the next 5 years - and the way information providers like CU distribute their wares.

While I am most interested in what [which] users will want to do with [what] thesauri, dictionaries, etc., my background inclines me to be curious about the other 'straw topics' as well. One topic of interest not mentioned in the workshop's advance materials is the interaction of human-generated with machine-generated vocabularies. Might strengths of the one correct weaknesses in the other? Should current work on standards consider how these discrete technologies may interoperate in the future?

I am currently a member of the ACM and SIGIR, and will be attending DL '98. I hope it is still possible to participate in the workshop, because it seems like a rare opportunity to meet with a geographically dispersed group of people face to face."

Traugott Koch is Senior librarian, Electronic Information Services at NetLab, Lund University Library Development Department, Sweden. He has developed digital library services during the last six years in European, Nordic and Swedish projects (among others the European DESIRE project and the Nordic Metadata Project). The focus in these projects is on resource discovery and retrieval, on resource description and metadata, knowledge organization, indexing and search services. During 1998 he is visiting scholar at OCLC Office of Research, Dublin, OH, working on problems in the intersection between metadata production, automatic classification and the retrievability of highly qualified subject information from heterogeneous Internet and metadata databases. He is a member of the Dublin Core Policy Advisory Committee.

We (Traugott and Anders Ardoe) expect the workshop to start an initial discussion on what vocabulary related operations have to be agreed upon as a basis for standards for using (distributed) vocabulary support over the Internet. In addition an orientation would be valuable what syntaxes and formats are promising for the task to encode and exchange the data. We hope a working group will be started to further this and related tasks.

the Computer Science Department of the UGA (University of Georgia). His MS and PhD backgrounds are in the database area and his primary interest is semantic integration and correlation of information. His research is now directed towards the ADL/ADEPT projects (Alexandria Digital Library/Alexandria Digital Earth Prototype Modeling System), where he is coordinating the implementation of the 'iscapes' (information landscapes), a collection of semantically related information assets, along with the ways to analyze and visualize them, that facilitate learning about the Digital Earth. His interest in the NKOS workshop is discussing the information integration in DL's using ontologies/meta thesauri inter-relationships across multiple learning domains. (added 8/12/99)


Steve Lussier is a Master's student in UC Berkeley's School of Information Management and Systems (SIMS), where he is studying the
development of digital libraries and documents, user interface design methods, and other shifting targets in informatics.  He is interested in the promise
of XML and RDF for combining flexibility with standardization in information systems.  He has had the opportunity to work this past Spring and
Summer with Dr. Stanley Blum at the California Academy of Sciences, deploying Academy collections-related databases, mostly of taxonomic
specimen  collections, on the Web, and doing planning and analysis toward the development of authority files and the resolution of other database integration issues.

"I believe the ongoing development of metadata and schema standards, in combination with work on thesauri and ontologies, will enable researchers
especially but by no means exclusively in the sciences to pursue new kinds of in-depth collaboration as well as solo research.  One area that has my
attention is bioinformatics (see for a current initiative).  I'm really interested in a whole raft of changes facing academic
and scientific information-sharing.  I suspect that we're going to see some disciplinary boundaries being rewritten as the task of integrating information
resources across those boundaries becomes a (relatively) more transparent one.  Helping enable those kinds of innovations while respecting the

Marsha Maguire is the Collections Librarian at the Experience Music Project, The Experience Music Project is an interactive, music-related museum opening next year at Seattle Center.  We (specifically, a team consisting of EMP librarians, programmers, and digitization and web technologists) are in the early stages of designing a digital library consisting of still images of our collections artifacts, and audio and moving image files made from our sound recordings and videos.  We hope to link these digital reproductions to our catalog records as well as to additional information prepared by the staff (interactive exhibit labels, kiosk presentations, web pages, etc.) and maybe OCR-scanned text such as notes, clippings, and the like.

EMP is developing an in-house thesaurus based on the Art & Architecture Thesaurus and incorporating ANSI thesaurus construction standards, although we have not yet linked the thesaurus database (which utilizes Liu Palmer's commercial thesaurus construction software) to our collections catalog database (an in-house, networked SQL Server database with Microsoft Access input forms and reporting capabilities} -- although we expect to redesign that database soon.  Work on the creation of name authority records has begun; these will be based on, but not always adhere to, AACR2/MARC.  Name authority records will be structured hierarchically to an extent, since we'll be creating authority records for, say, rock bands and the individual members of those bands, and providing links to other bands in which those musicians have performed. We have not developed a search interface yet, but are hoping to develop a very user-friendly searching/browsing/linking system to offer visitors to the museum, serious researchers, and users of the World Wide Web. We're interested in how Z39.50, XML, and other emerging standards might improve access not only to our digital resources, but to the vast store of cultural information held by institutions throughout the world.


Jim Markham has been the Aquatic Sciences/Biology/German Librarian, as well as the Original Cataloger for Science and German at the University of
California, Santa Barbara, since 1986. In his first career, he was a grant-supported research marine botanist (Ph.D. University of British Columbia) at UBC, Vancouver, B.C.; NRC Canada Atlantic Regional Lab, Halifax, N.S.; and Biologische Anstalt Helgoland, Helgoland, Germany.

Since 1985 he has been a member of IAMSLIC (International Association of Aquatic and Marine Science Libraries and Information Centers) and since 1987 Chair of the IAMSLIC Coordinating Committee on Subject Analysis. The CCSA is concerned with the ASFIS (Aquatic Sciences and Fisheries Information System) Thesaurus, which is used for indexing and searching  the international database Aquatic Sciences and Fisheries Abstracts (ASFA), as well as for cataloging of aquatic science materials in many countries where Library of Congress Subject Headings are not used. The ASFIS Thesaurus is the most widely used thesaurus worldwide for aquatic
science. The Committee was formed as a result of a paper presented by Jim Markham at IAMSLIC 1987, comparing Library of Congress Subject Headings with the ASFIS Thesaurus, for the benefit of catalogers who find the ASFIS Thesaurus more appropriate for aquatic or marine science materials, but are required by cataloging rules to use LCSH when cataloging these materials.

The Committee was formed October 1987 with the following charges:
"1.  To act as a clearinghouse and lobbying focus for IAMSLIC members' suggestions to add or change subject terms in both the ASFIS Thesaurus
and the Library of Congress Subject Headings and;
2.  Coordinate production of a document to map the ASFIS Thesaurus terms with LCSH."

Various approaches have been tried to carry out the second charge. At first, a long table was nearly finished, which simply matched ASFIS terms with their nearest LCSH equivalent, but it was never completely finished and while it was being prepared, both LCSH and ASFIS were updated. It is meant to be a working tool for catalogers, but publication, distribution and updating were not resolved. With the advent of the World Wide Web, it now seems that the best approach would be a searchable Web page, listing all ASFIS terms (some 6000+) and as many LCSH as are necessary to provide equivalents. We note that approximately half of the ASFIS terms still do not have adequate LCSH equivalents. We are still searching for a practical way to build this Web page. Meanwhile, IAMSLIC members worldwide are
eagerly awaiting the finished product.

Jessica Milstead is Principal of The JELEM Company, a consulting firm specializing in index and thesaurus design, and in development of machine-aided indexing systems.  She took her masters and doctorate in information science and librarianship from Columbia University.  She taught cataloging, indexing and information science on library school faculties for a number of years before going into industry, where she was developer and editor of a number of indexes to newspapers and scholarly works.  In 1986 she founded The JELEM Company, and has served clients as an independent consultant since then.  She has been active in NISO standards work, has published extensively in the field, and offers workshops on vocabulary management.

Interest statement:  The environment within which vocabularies for providing access to information are developed and used is undergoing dramatic change. The old pattern of development by a single organization for its own use, with application by specially trained experts, is no longer viable. Creator-applied metadata and machine-aided and automatic indexing are just two developments which are having a major impact on vocabulary development -- and of course the use of natural language processing sometimes replaces
use of any indexing vocabulary at all.  I am concerned with all of these developments; I wish both to remain current with this rapidly changing area and to contribute to its growth. (revised June 14, 1999).

Leah Prescott works at Mystic Seaport Museum, Inc.  as Collections Information Technology Coordinator and is responsible for the coordination and implementation of data standards across all library and curatorial divisions. She is the chief authority within the museum for controlled vocabulary and terminology issues.  She is currently chairman of the Controlled Vocabulary Special Interest Group for the Museum Computer Network and will be leading a conference session concerning term research for thesaurus construction.  For several years she has collaborated with the Getty Information Institute's Art and Architecture Thesaurus on term research needed to incorporate maritime vocabulary into the AAT and more recently the Thesaurus of Geographic Names.

Mystic Seaport is currently involved in an ambitious project to create an integrated information system which will effectively tie together at least two major databases, a library system (VOYAGER by Endeavor) and a collections maintenance system (MULTIMIMSY by Willoughby Associates).  As our goal is to provide effective access for a broad range of users, we have spent considerable time over the past several years defining and refining our controlled vocabulary both for internal use and to contribute to standards within the domain of maritime history.  We are currently struggling with finding effective ways to enable our component systems to access shared authority files as well as thesauri so that we can offer high precision/controlled vocabulary information retrieval, as well as more effective keyword search strategies.  This workshop will be highly relevant to our efforts as well as of great interest to me.

Lori J. Starr serves as Head of the Thesaurus Section of the Indexing Branch at the National Agricultural Library.  The Thesaurus Section works cooperatively with CAB International to develop and maintain the CAB Thesaurus, which is the controlled vocabulary for indexing records contained in NAL's bibliographic database, AGRICOLA (Agriculture OnLine Access). The Thesaurus Section maintains an internal thesaurus file for NAL staff.  Additionally, Lori serves as a consultant to the Food and Agriculture Organization of the United Nations for maintenance of the English version of AGROVOC, which is the controlled vocabulary of the multilingual AGRIS database.  NAL, in partnership with FAO and CAB International, initiated a Unified Agricultural Thesaurus Project in 1989 which resulted in (1) a classified version of AGROVOC and (2) an overall UAT Classification that encompasses the subject areas of both AGROVOC and CAB Thesaurus.  Lori's next challenge is to provide a classification structure for AgNIC (Agriculture Network Information Center).  NAL is anticipating the release of AGRICOLA on the Internet.

"With the introduction of NAL's database, AGRICOLA, on the Internet, this raises questions of how NAL can most effectively aid retrieval in this large (3 million+ records) database to a variety of users.  I believe that thesauri are generally undervalued and they are usually seen as monsters that slow database production, are not used by searchers, and eat up staff resources to maintain.  My personal goal is to bring the positive aspects of thesauri "out of the closet" and demonstrate how the hierarchical structure and relationships contained in the thesaurus can positively enhance retrieval in an Internet environment.  Other databases on the Internet are already doing this.  How can a network of thesauri further enable retrieval?  What structure needs to be in place at NAL for data exchange?  Listening to what others envision for the future and how I can apply this to the AGRICOLA database are my goals at the workshop."

Douglas Tudhope is with the Computer Studies Department at the University of Glamorgan, Wales, UK and is the Editor of New Review of Hypermedia and Multimedia. Six years ago the University was commissioned to build a hypermedia museum exhibit on local history from the photographic archives of the Pontypridd Historical and Cultural Centre. This inspired a University research assistantship in collaboration with PHCC that resulted in Carl Taylor's PhD work on semantic modelling and navigation in museum hypermedia systems. As part of this work, a number of research prototypes were built investigating a hypermedia architecture with a semantic index space separate from the document space (Beynon-Davies et al 1994, Taylor et al 1994). A variety of conventional hypermedia navigation techniques were implemented with this architecture (Tudhope et al 1994). Primary access routes were time, space and as subject index the Social History and Industrial Classification (SHIC). Rather than using fixed embedded links, navigation was based on queries over an underlying semantic index space, with results post-processed for expression in a particular navigation tool. Queries to the database can be simple or complex. Conventional hypermedia navigation techniques, including both local and global browsers, guided tours, and Boolean queries can be implemented by relatively simple underlying queries. More complex queries return partial matches using measures of semantic closeness between terms in a semantic index space; advanced navigation options included query expansion when a query fails to return results and navigation via similarity to current item (Cunliffe, Taylor, Tudhope 1997).  Most existing commercial museum access systems using thesauri rely on interactive approaches or limited query expansion techniques. A classification system, or thesaurus, embodies a semantic network of relationships between terms, the three main thesaurus relationships being hierarchical, associative and equivalence. Thus there is some inherent notion of distance between terms, their 'semantic closeness'. Distance measurements can be exploited to provide more advanced navigation tools. A distance measurement between terms (and between sets of terms) offers the opportunity for imprecise information requests.  Semantic term expansion lies at the heart of the measures of closeness between terms in automated term expansion and similarity measures in retrieval tools.

The intention in future research is to build on the principles underlying the semantic index space, extending the semantic model to a full set of thesaurus relationships, and investigate the potential of intelligent navigation tools in a major museum which can facilitate evaluation. We are currently implementing underlying models in both relational and semantic database systems. One issue under consideration is how these tools can be utilised in a networked environment and how the thesaurus structure and query engine parameters should be visualised to the user. Our research focus and collaborations in the museum domain, where there has been recent work on user query analysis and modelling, may enrich discussion in the workshop.

Diane Vizine-Goetz is a Research Scientist in the OCLC Office of Research.  She is team leader of the knowledge organization research (KOR) team which has had a long-standing involvement in information organization using classification systems and controlled vocabularies. When Forest Press, publisher of the Dewey Decimal Classification (DDC), became a division of OCLC in 1988, the KOR team prototyped classifier-assistance tools based on the electronic version of the DDC. Electronic Dewey and Dewey for Windows are OCLC products that resulted from that research.

The KOR team is currently investigating techniques for automatically associating subject-access systems like the DDC and the Library of Congress Subject Headings for the purpose of expanding the vocabulary of the DDC.  Mapping between schemes is accomplished through the application of corpus-based natural language processing techniques and statistical information retrieval techniques. Terminology mapped in this way often represents current and popular topics not represented by existing captions or Dewey index terms but within the scope of Dewey knowledge structure. These new associations (from free text and controlled indexing systems) are being used to enhance the database components of automated and semi-automated systems that automatically assign subjects to electronic documents. This work and research to transform the captions of the DDC into end-user language are aimed at improving category-based access to electronic documents and making traditional subject access systems more hospitable for use in a distributed information environment.

Ron Vogel is an oceanographer with NASA's Global Change Master Directory, an online directory for scientists to locate data sources in the Earth and environmental sciences.  He has worked on the development of a controlled vocabulary for Earth science metadata and on interoperability of metadata between various geospatial data providers.

By restructuring various classification schemes from multiple providers into a single metadata format (keeping each classification scheme distinct through the use of a database tag), metadata documents could thus be entered into a single database and searched.  However, users still had to select one of various classification schemes when conducting a search.

In order to allow seamless searching of all metadata documents, a mapping between vocabularies could allow documents from the various providers to be found.  While all the classification schemes are environmental, they do not all cover the exact same environmental domains.  In those instances where one classification scheme cannot be mapped 100% to another classification scheme, the documents must be retrieved by other means.

Furthermore, in order to move to a distributed search environment where users may search by one classification and retrieve documents indexed with another, metadata structures with increased flexibility are necessary.  Is it possible to incorporate multiple classification schemes into single or multiple metadata formats and still allow seamless document searches?

Richard White graduated in Botany & Zoology from Bristol, UK, and completed a PhD in Liverpool, UK, on the local evolution of a colony-forming day-flying moth, relating population dynamics and colony separation to morphological differentiation.  However, since coming to Southampton in 1976, he has supported the use of computers in biodiversity research and teaching, specialising in software development for biological applications, including the design, organisation and implementation of biodiversity databases, pages and databases on the World-wide Web, and algorithms and software to make outline shape and pattern measurements from images of biological objects.

His work in biodiversity databases is currently focussed on ways to link them together on the Web. He built the Web version of the ILDIS database on the plant family Leguminosae (, which is now a prototype component of the Species 2000 project to create a virtual catalogue of (eventually) all the world's species of plants and animals (  It  will allow users to follow links to other sources of information about species.  The choice of the technology for Species 2000 and problems arising from certain ambiguities in the use of species names are being addressed in the SPICE ( and LITCHI ( projects, respectively.

Marcia Lei Zeng is an Associate Professor in the School of Library and Information Science at Kent State University, with major research interests in knowledge organization and representation, thesaurus and other indexing languages, information storage and retrieval systems, indexing systems and software, and multilingual information processing.  Recently she has been working on three projects that are related to this workshop's theme: (1) the design and development of a visual terminology database for medicinal herbs which is one component of the Complementary and Alternative Medicine Digital Library, a joint project of her and three other P.I.s in Columbia University.  In this project she also developed an online-classification scheme which is used in guided Internet searching for alternative medicine, implemented through JavaScript;  (2) a pilot digital library project for a historical fashion collection at Kent State University, where specialized thesauri and metadata have been studied under her supervision; and (3) during the last two years, she has generated various HTML-based templates for publishing thesauri and indexes on the WWW.

Her major purposes of participating in this workshop are to share with others the specific considerations about presenting thesaurus/classification systems on networked environments and to contribute to the discussions of an XML definition for a thesaurus or a general scenario for searching and navigating a networked thesaurus or classification system.  In addition, she wishes to share experiences and explore alternative approaches to vocabulary control in the networked environment for specific subject areas which have strong multi-cultural and multi-lingual aspects.
