by TekStalker Ltd.

  Imports texts from file systems, mailboxes, databases and WWW (including automated search for documents semantically similar to a given one), processes them (automatically recognizes language, purifies, parses), researches them with exploration engines such as Key Concepts Extraction (statistically determinates key concepts and stable links between them, persons’, organizations’ and geographical names, non-vocabulary stable phrases characteristic for the text), draws graphs of concepts links, classifies texts (making categorization trees by itself or filling rubricators made by user), summarizes texts, makes the all-in-one package analysis. Results can be exported as files or into databases. "Remembers" the whole document flow for further reproducing it whenever you need it.
