Abstract: Textual documents are readily classified and/or characterized with respect to other documents by determining a corresponding level of semantic distance between such documents. For example, particular parts of speech are identified, and those words in the documents that correspond to such parts of speech are identified and extracted. Matches of such wording between the documents permit identification of a given corresponding semantic distance value. When no matches occur (or when otherwise desired), synonyms for such words can be used to ascertain more distant semantic relationships. The process can be repeated in an iterative fashion using ever-deepening tiers of synonyms.
