The workshop will 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 model the underlying semantic structure of a domain for purposes of information retrieval, knowledge discovery, language engineering, etc. The workshop provides an opportunity to discuss projects, research and development activities, evaluation approaches, lessons learned, and research findings. The main theme of the workshop is Designing for Cultural Hospitality and Indigenous Knowledge in KOS.
