Abstract
An investigation is reported of ways to take advantage of the
semantics in thesauri to improve: (1) indexing by providing descriptions
of documents as sets of terms from the thesaurus; and (2) retrieval by
assessing the relevance of documents to a query. Thesauri need to be
updated to account for the evolution of the field they cover.
Accordingly, various augmentation algorithms and methods to assess the
usefulness of these augmentations are being studied. The augmentations
consist of merging two existing thesauri. By keeping a consistent level
of complexity among the structure manipulated by the merging algorithm,
the reasoning method, and the evaluation procedure, an improvement of
the performance of the merged thesaurus on both document indexing and
retrieval is demonstrated
