DESIRE Toolkit Components2.11 MatcherDescriptionThe Matcher tool implements a subject classification process using a subject-specific thesaurus by which terms are intellectually mapped to categories or subject classes. The classification process is made up of several steps. First, the document to be classified is fetched. Text is extracted from this document, and all thesaurus terms are matched to it. Some heuristic processing rules are applied to the results from the matching process. Finally, the outcome is formatted either for presentation or for storing in a database.
