Networked Knowledge Organization
Systems/Services/Structures
N K O S

NKOS is devoted to the discussion of the functional and data model for enabling knowledge organization systems/services (KOS), such as classification systems, thesauri, gazetteers, and ontologies, as networked interactive information services to support the description and retrieval of diverse information resources through the Internet.

Knowledge Organization Systems/Services (KOS) model the underlying semantic structure of a domain. Embodied as Web-based services, they can facilitate resource discovery and retrieval. They act as semantic road maps and make possible a common orientation by indexers and future users (whether human or machine). -- Douglas Tudhope, Traugott Koch, New Applications of Knowledge Organization Systems

Announcement

13th European Networked Knowledge Organization Systems (NKOS) Workshop
To be held during the DL2014 Conference in London
Thursday 11th - Friday 12th September 2014
Call for Papers
Submission deadline: Monday 23rd June 2014
Notification of acceptance: Monday 14th July 2014

Available now:

ISO published ISO 25964-2 the standard for interoperability of thesauri on 4 March 2013. ISO 25964-2 deals with interoperability between thesauri and other vocabularies, especially the principles and practice of mapping between them. Types of vocabulary to be considered include classification schemes (including those for records management), taxonomies, subject heading schemes, name authority lists, ontologies, terminologies, and synonym rings.
