Method and apparatus for classifying documents within a class hierarchy creating term vector, term file and relevance ranking

摘要

A method for classifying a document based on content within a class hierarchy. The class hierarchy comprises a plurality of category nodes stored within a tree data structure. Each of the plurality of category nodes includes a category name corresponding to a unique directory and a category definition comprising a set of defining terms. The class hierarchy is searched to determine appropriate categories for classification of the document. The document is then stored in directories corresponding to the categories selected for classification. If no categories are produced by the search, a system administrator is notified of the unsuccessful search.
