NKOS Special Session at DC-2005"Enhancing the Understanding of Meaning: Practical Applications of Networked Knowledge Organization Systems (NKOS)"Carlos III University of Madrid (Leganés), Seminar Room 4.1.E0313 September 2005Organizers: Gail Hodge, Traugott Koch and Douglas Tudhope |

Metadata has significantly enhanced access to digital resources, categorizing Web pages and providing text searching for non-text objects. The semantics (the meaning) encapsulated in this metadata has been determined largely at the level of individual projects or digital library collections. However, new demands for interoperability are coming from enterprise applications, communities of practice, and the vision of the Semantic Web. What roles can Knowledge Organization Systems (KOS), such as thesauri, classification schemes, and ontologies play in improving the understanding of meaning? What best practices, tools, and services are being deployed in practical applications? What are the outstanding issues and what research agenda should KOS and metadata practitioners undertake jointly? What are the connections with related DC activities, such as semantic web applications, linguistics developments and registry work? These sessions, organized by members of the NKOS Working Group, will gather metadata and KOS practitioners to demonstrate accomplishments and to discuss current and future efforts. Time will be allocated for question and answer sessions and general discussion.
The NKOS Special Session is in two parts with a break in the middle. The first part showcases four activities aimed at improving the semantics of metadata.
The second part begins with case studies from two specific communities. It concludes with a Question & Answer session aimed at sharing experiences from the audience and reactions from a panel of experts in metadata and KOS.
The special session is part of DC-2005, International Conference on Dublin Core and Metadata Applications. For participation please register with the conference at http://dc2005.uc3m.es/.

A Pilot SKOS API Web Service Browser: The Role of KOS and Ontologies Reflections on experiences developing a pilot Web Service Browser, based on the SKOS API. Lessons for future evolution of protocols for programmatic access to thesauri and related KOS. How should RDF representations of KOS be used in Semantic Web and other applications? How should KOS relate to Ontologies? Presentation: [Powerpoint] |
| Rachel Heery, UKOLN, University of Bath | (Metadata and) Vocabulary Registries Why are vocabulary registries needed? What do they need to contain? How will they be used? Registries as part of a digital infrastructure vs. individual declaration of terms. What can we learn from registries in other contexts? Overview of vocabulary registry initiatives. Presentation: [Powerpoint] |
| Andy Powell, UKOLN, University of Bath | Persistent Identifiers of Concepts/Terms/Relationships - a DCMI perspective Why are identifiers of conceptual resources needed to support knowledge organization and the conveyance of meaning? Is there any difference, e.g. regarding specific requirements, between identifiers for e.g. documents and people and identifiers for terminology? What is current best practice regarding creation, application and registration of identifiers for terminology? How will term identifiers work in distributed terminology applications on the (semantic) web? Presentation: [Powerpoint] |
| Eric Childress, OCLC | Ideas and activities with respect to identifiers in the context of the Dewey Decimal Classification Presentation: [Powerpoint] |

| Gail Hodge, Information International Assoc. | Case Studies from the National Biological Information Infrastructure and the NASA Goddard Library How can the Dublin Core and knowledge organization systems be used in a heterogeneous project-based environment that also needs to preserve consistency for federated searching? How can knowledge organization systems link local digital repositories to organization-wide efforts? What is the framework for supporting an environment where projects are continuously added, thereby changing the metadata and vocabulary needs? Presentation: [Powerpoint] |
| Gail Hodge (chair) | Introduction |
