Abstract

The question posed in this thesis is whether the effectiveness of the rule-based approach to automatic text categorization on OCR collections can be improved by using domain-specific thesauri. A rule-based categorizer was constructed consisting of a C++ program called C-KANT which consults documents and creates a program which can be executed by the CLIPS expert system shell. A series of tests using domain-specific thesauri revealed that a query expansion approach to rule-based automatic text categorization using domain-dependent thesauri will not improve the categorization of OCR texts. Although some improvement to categorization could be made using rules over a mixture of thesauri, the improvements were not significantly large.
