Abstract

This paper concerns the use and evaluation of a thesaurus-based query expansion method in information retrieval. The query expansion process assigns weights to different types of relations obtained fom vocabulary structures, providing an efficient way to measure distance measure between different terms. This method, tested for Portuguese, improved the overall information retrieval performance on small corpora and over the Internet.
