The CSA/NBII Biocomplexity Thesaurus is now available via a Web services (SOAP) interface. A description of the contents of the thesaurus are available on the NBII Web site at http://thesaurus.nbii.gov/.

CERES and National Biological Information Infrastructure (NBII) Biological Resources Division (BRD) are collaborating on the development of an Integrated Environmental Thesaurus and Thesaurus Networking Tool Set for Metadata Development and Keyword Searching.

The Biomedical Grid Terminology (BiomedGT) is an open, collaboratively developed terminology for translational research. BiomedGT builds on the strengths of the NCI Thesaurus, including concept orientation, description logic, and public accessibility. While the current terminology has been seeded with NCI Thesaurus content, it is being restructured to facilitate open content development. The goal is to evolve BiomedGT into a set of federated sub-terminologies, with content maintained by experts in the relevant research communities.

Eurovoc is a multilingual thesaurus covering the fields in which the European Communities are active; it provides a means of indexing the documents in the documentation systems of the European institutions and of their users. The European Parliament, the Office for Official Publications of the European Communities, the national and regional parliaments in Europe, some national government departments and European organisations are currently using this controlled vocabulary.

Andreas Hotho's talk more specifically addressed the search for methods to identify tags which describe the same concept (or a more specific / a more general concept respectively) within a folksonomy. He suggested two approaches: 1. Applying measures directly to folksonomy statistics, allowing to describe tags as a vector; e.g. co-occurrence frequency and FolkRank could serve as a similarity measure (with these two having a tendency towards high-frequency tags) or a cosine method (which is more likely to produce "siblings") 2. Looking up tags in an external thesaurus/vocabulary (for instance achieving semantic grounding by mapping a tag and its most similar tags with Wordnet Synsets)
