Extractor is a software text summarization engine. It consumes documents (text, html, email) and using a patented genetic extraction algorithm (GenEx) analyzes the recurrence of words and phrases, their proximity to one another, and the uniqueness of the words to a particular document. The engine returns a list of key words and phrases found in the document together with their relative ranking (how many times was the word/phrase found in the document) along with contextual links back to the position of the key word/phrase in the document itself.
