NKOS 2025 will be held in TPDL 2025, the 29th International Conference on Theory and Practice of Digital Libraries (TPDL), 23-26 September 2025, Tampere, Finland [https://tpdl2025.github.io/]
Call for Proposals
The workshop aims to explore the potential of Knowledge Organization Systems (KOS), such as classification systems, taxonomies, thesauri, ontologies, and lexical databases, in the context of current developments and possibilities. These tools help to model the underlying semantic structure of a domain for purposes of information retrieval, knowledge discovery, language engineering, and the Semantic Web. The workshop will provide an opportunity to discuss projects, research and development activities, evaluation approaches, lessons learned, and research findings. A further objective is to systematically engage in discussions in common areas of interest with selected related communities and to investigate potential cooperation.
The workshop will also allow major projects to report results, newcomers to interact with established people in the field, while facilitating the discussions of topical issues which require consensus or coordination, including standards efforts. Thus, for example, previous workshops have seen focused discussion on KOS in AI & AI in KOS, early drafts of BSI and ISO KOS standards, the W3C SKOS standard, the interface between traditional library and information science vocabularies and Semantic Web efforts, KOS linked data, social tagging and its relation to established vocabularies, KOS metadata and the different types of KOS, use of KOS in artificial intelligence. The TPDL venue affords participation by KOS researchers and developers from different perspectives (reflecting the different conference threads), such as KOS design and construction, API and service developers, user-oriented issues, management of KOS in registries.
2025 NKOS Workshop Themes
The workshop has two themes as the main focus:
1) KOS mappings. Mappings (or alignment) between KOS is attracting increasing attention with the expression of KOS as Linked Data and multilingual archives.
2) Users interaction with KOS in retrieval including semantic search.
Further presentations/demonstrations will be selected from the following topics:
3) Automatic/AI KOS-based subject indexing / classification /entity-extraction.
4) KOS-based recommender systems.
5) Meaningful concept display and meaningful visualization of KOS.
6) Standards developments.
7) Evaluation of KOS-based systems – methods and practical experience.
8) KOS in e-Research metadata contexts.
9) KOS and (e)learning.
10) Use of KOS in Artificial Intelligence (AI) applications - methods and practical experience.
Important Dates

Proposal Submission
Proposals are invited for 20-minute presentations and demos or 60-minute panels on work related to the themes of the workshop (above). We welcome presentations, demos and panels related to themes, in-process projects, and ongoing work.
Please email proposals (maximum 1000 words including aims, methods, background, main findings, and relevance to themes of workshop) to Koraljka Golub (koraljka.golub@lnu.se) and Claudio Gnoli (claudio.gnoli@unipv.it).
Proposals will be peer-reviewed by the Program Committee.
Participation in the in-person workshop will require registration; please consult the TPDL 2025 website for registration and cost information. After the workshop, copies the presentations will be made available on the NKOS website.
Papers developed from some earlier workshop presentations were published as special issues in journals such as Journal of Data and Information Science and Knowledge Organization. In case of interest, we shall aim for special journal issue to host papers from the 2025 workshop.

NKOS (Networked Knowledge Organization Systems) is an ad hoc work group of more than 300 international experts and implementers of knowledge organization systems. NKOS is devoted to 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.
