21. A system for retrieving task information using task-based indexes, the system comprising: a memory and a processor including computer-readable instructions for causing the system to: acquire a plurality of mutually exclusive task-based categories, where L is the number of task based categories; receive a plurality of text documents, where D is the number of text based documents; partition the text documents into a plurality of document sets, where N is the number of document sets, such that each task-based Category is associated with a document set, where each document set is comprised of at least one document having subparts and having task information described in the document; associate at least one task-descriptive symbol with each task-based category, index the documents in each document set to create an index having index words and pointers, where the index words reflect the task information in the documents or subparts of documents; correlate the task-descriptive symbols with the index words to create an alignment of words having similar meaning such that index words are matched with similar task-descriptive symbols; and form a plurality of task-based indexes by grouping the alignment of words with the respective task-based category, where M is the number of task-based indexes, and where L is equal to N, which is equal to M, which is less than or equal to D, such that retrieval of a document having task based information pertaining to the task descriptive symbols is a function of the task based index.

A system for retrieving task information as set forth in claim 21 , wherein the system is further configured to update the task-based index as new documents are available.
