Abstract
A rule-based automatic text categorizer was tested to see if two types of thesaurus expansion, called query expansion and Junker expansion respectively, would improve categorization. Thesauri used were domain-specific to an OCR (Optical Character Recognition) test collection focussed on a single topic. Results show that neither type of expansion significantly improved categorization.
