Talk by Ricardo Eito-Brun, Universidad Carlos III de Madrid, Spain

The lack of well-defined indexing practices is a common problem in most institutional repositories. Researchers typically assign keywords to their submissions, these terms, however are not extracted from a controlled vocabulary or thesaurus. This leads to ambiguity and lack of specificity in the terms which are used to describe the content of their contributions.
This presentation describes an approach used to complete the automatic assignment of descriptors and keywords taken from a thesaurus (the UNESCO thesaurus) to contributions which had already been published. The process is run with the help of an existing commercial tool, PoolParty. The experiment runs a process to automatically identify the thesaurus descriptors that describe the content of the documents published in the institutional repository of a Spanish university.
Once the thesaurus descriptors are assigned to the existing documents, it is feasible to use the theasurus to expand queries and to assist end-users in the selection of search terms. This brings about improved search capabilities, as users are in a position to identify both, additional related terms andmore general and specific terms in order to improve their search queries.
