Abstract
A document classification system includes disambiguation processing to validate categories that have been preliminarily classified for themes of a document. The themes of a document are preliminarily classified through use of a classification hierarchy that contains a plurality of categories. The disambiguation processing determines, for a theme selected for disambiguation, whether the category preliminarily classified for the theme selected is valid by analyzing the relationships among the category preliminarily classified for the theme and other categories classified for different themes in the document. The disambiguation processing also utilizes a category cross reference database, which comprises a list of category cross reference pairs, to disambiguate categories assigned to themes by pairing a category classified for a theme and other categories classified for other themes in the document and by comparing these category pairs with category cross reference database pairs. If a match occurs, then the categories of a document category pair are validated.
