In general, the system and method provides for blending statistical, syntactic and semantic considerations to learn classifiers from an organization's unclassified internal and external unstructured text documents, as well as unclassified documents available via the Internet. In one form, for each class in a taxonomy the class name is expanded into semantically related words and phrases to build approximate classifiers. Each approximate classifier will almost certainly be erroneous but it can be used to identify an approximately correct set of documents. The process is recursive; e.g. the approximate classifier with the strongest evidence, is fed back into the system until a stale set of the strongest terms for each classifier has been selected.
