Abstract
A method for filtering documents includes receiving the document off of a multicast channel. It is determined whether the document includes relevant information. The document is processed if it includes relevant information. A filtering agent includes a session identification reading unit that retrieves a session identification from a document transmitted over a multicast channel. The filtering agent also includes an information classification unit that retrieves meta data from the document. The filtering agent also includes a source unit that retrieves source information from the document. An evaluation unit is coupled to the session identification reading unit, information classification unit, and the source unit. The evaluation unit determines whether the document includes relevant information based on the session identification, meta data, and the source information.
