Kinds of Tags: a collaborative research study on tag usage and structure
KoT (Kinds of Tags) is an ongoing joint collaborative research effort with many participants worldwide, including the University of Minho, UKOLN, the University of Bologna, the Université Libre de Bruxelles and La Universidad Carlos III de Madrid. It is focused on the analysis of tags that are in common use in the practice of social tagging, with the aim of discovering how easily tags can be ‘normalised’ for interoperability with standard metadata environments such as the DC Metadata Terms.

Stella Dextre Clarke – Panel Subsession Proposal
Project ISO NP 25964: Structured vocabularies for information retrieval
ISO 2788 and ISO 5964, the international standards for monolingual and multilingual thesauri respectively dated 1986 and 1985, are very much in need of revision. A proposal to revise them was recently approved by the relevant subcommittee, ISO TC46/SC9. The work will be based on BS 8723, a five part standard of which Parts 1 and 2 were published in 2005, Parts 3 and 4 are scheduled for publication in 2007, and Part 5 is still in draft. This subsession will address aspects of the whole revision project. It is conceived as a panel session starting with a brief overview from the project leader. Then there are three presentations of 15 minutes, plus 5 minutes each for specific questions. At the end we have 20 minutes for questions to any or all of the panel, and discussion of issues from the workshop participants.

Facet analysis as a fundamental theory for structuring subject organization tools
The presentation will examine the potential of facet analysis as a basis for determining status and relationships of concepts in subject based tools using a controlled vocabulary, and the extent to which it can be used as a general theory of knowledge organization as opposed to a methodology for structuring classifications only.

Towards the “webification” of controlled subject vocabulary: A case study involving the Dewey Decimal Classification
The presentation will briefly introduce a series of major principles for bringing subject terminology to the network level. A closer look at one KOS in particular, the Dewey Decimal Classification, should help to gain more insight into the perceived difficulties and potential benefits of building taxonomy services out and on top of classic large-scale vocabularies or taxonomies.

With the increasing requirement of establishing semantic mappings between different vocabularies, further development of these encoding formats is becoming more and more important. For this reason, four types of knowledge representation formats were assessed:MARC21 for Classification Data in XML, Zthes XML Schema, XTM(XML Topic Map), and SKOS (Simple Knowledge Organisation System). This paper explores the potential of adapting these representation formats to support different semantic mapping methods, and discusses the implication of extending them to represent more complex KOS.

Uniform SPARQL Access to Interlinked (Digital Library) Sources
In this presentation, we therefore focus on a solution for providing uniform access to Digital Libraries and other online services. In order to enable uniform query access to heterogeneous sources, we must provide metadata interoperability in a way that a query language – in this case SPARQL – can cope with the incompatibility of the metadata in various sources without changing their already existing information models.

Collaborative Building of Controlled Vocabulary Crosswalks
One of the main features of classic libraries is metadata, which also is the key aspect of the Semantic Web. Librarians in the process of resources annotation use different kinds of Knowledge Organization Systems; KOS range from controlled vocabularies to classifications and categories (e.g., taxonomies) and to relationship lists (e.g., thesauri). The diversity of controlled vocabularies, used by various libraries and organizations, became a bottleneck for efficient information exchange between different entities. Even though a simple one-to-one mapping could be established, based on the similarities between names of concepts, we cannot derive information about the hierarchy between concepts from two different KOS. One of the solutions to this problem is to create an algorithm based on data delivered by large community of users using many classification schemata at once. The rationale behind it is that similar resources can be described by equivalent concepts taken from different taxonomies. The more annotations are collected, the more precise the result of this crosswalk will be.
