Detecting and tracking new events/classes of documents in a data base
First Claim
1. A method for detecting new events and/or classes of documents and tracking evolution thereof in a database, said new events and/or classes of said documents being added to said database, said documents including attribute data related to a temporal parameter, said method comprising the steps of:
- providing vectors of said documents based on attribute data that includes said temporal parameter, and detecting said new events and/or classes of said documents and tracking evolution thereof using said vectors, wherein said tracking comprises evaluating vectors to determine whether said documents relate to new, follow-up, or old events and/or new, follow-up, or old classes.
