From IOP Publishing:
The American Institute of Physics (AIP) and IOP Publishing (IOP) have jointly announced the gift of a new astronomy thesaurus called the Unified Astronomy Thesaurus (UAT) to the American Astronomical Society (AAS) that will help improve future information discovery for researchers.
[Our emphasis] The AAS will make the UAT freely available for development and use within the astronomy community, while ensuring the thesaurus remains relevant and useful. Further development of the UAT will be undertaken by the John G. Wolbach Library at the Harvard-Smithsonian Center for Astrophysics in collaboration with the Astrophysics Data System (ADS) and the International Virtual Observatory Alliance (IVOA) to enhance and extend the thesaurus to ensure that it continues to meet the needs of the astronomy community.
The thesaurus will be used in semantic technologies. With many thousands of resources being published each year in the field of astronomy, these kinds of tools are vital to ensure that researchers continue to be able to find relevant information quickly and ultimately improve the discoverability of research. This applies as much to data, web services and other resources, as it does to the bibliographic resources to which thesauri have traditionally been applied.
The work to combine the thesauri has been carried out by Access Innovations Inc, a privately held company that specializes in information management and database creation products and services.
