Abstract
A computer system configured to implement a method for document analysis and retrieval. A document that includes text is received from a host. Document keys (i.e., keywords and keyphrases) associated with the text are generated. In first embodiments, a provided document taxonomy has categories and associated category keys (i.e., keywords and keyphrases). The category keys of each category are compared with the document keys to determine a distance between the document and each category as a measure of how close the document is to each category. A subset of the categories is returned to the host, wherein the subset of the categories reflects the determined distances. In second embodiments, a search string is created as a logical function of a subset of the document keys. The search string is submitted to a search engine. Links to related documents are received from the search engine and returned to the host.
