Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
74 words
A method comprising: automatically defining a set of preferences for each local computing resource that determines what information is relevant to the local computing resource; receiving a document from a multicast channel, determining if the document includes relevant information by reading published meta tags in the document for meta data, and determining whether the meta data is of interest to the local computing resource; and processing the document if the document includes relevant information.
Claim 2
Independent Claim
74 words
A method comprising: automatically defining a set of preferences for each local computing resource that determines what information is relevant to the local computing resource; receiving a document from a multicast channel, determining if the document includes relevant information by reading published meta tags in the document for meta data, and determining whether the meta data is of interest to the local computing resource; and processing the document if the document includes relevant information.
Claim 3
Dependent Claim
43 words
The method of claim 1 , wherein determining if the document includes relevant information further comprises: obtaining a session identification associated with a request for the document; and determining whether the session identification corresponds to an active session run on a client terminal.
Claim 4
Dependent Claim
26 words
The method of claim 1 , wherein reading published meta tags in the document for the meta data further comprises analyzing the content of the document.
Claim 5
Dependent Claim
39 words
The method of claim 1 , wherein determining whether the meta data is of interest to the local computing resource comprises referencing a local information profile to determine whether the meta data is indexed in the local information profile.
Claim 6
Dependent Claim
40 words
The method of claim 1 , wherein determining if the document includes relevant information further comprises: obtaining source information associated with the document; and determining whether the source information corresponds to the set of preferences for the local computing resource.
Claim 7
Dependent Claim
39 words
The method of claim 1 , wherein determining whether the source information is of interest to the local computing resource comprises referencing a local information profile to determine whether the source information is indexed in the local information profile.
Claim 8
Dependent Claim
22 words
The method of claim 1 , wherein processing the document comprises forwarding the document to a client terminal that requested the document.
Claim 9
Dependent Claim
18 words
The method of claim 1 , wherein processing the document comprises caching the document in a storage device.
Claim 10
Dependent Claim
94 words
An article comprising a computer-readable medium having stored thereon a sequence of instructions that, when executed, cause one or more electronic systems to: automatically define a set of preferences for each local computing resource that determines what information is relevant to the local computing resource; receive a document from a multicast channel; determine whether the document includes relevant information by reading published meta tags in the document for meta data, and determining whether the meta data is of interest to the local computing resource; and process the document if the document includes relevant information.
Claim 11
Dependent Claim
94 words
An article comprising a computer-readable medium having stored thereon a sequence of instructions that, when executed, cause one or more electronic systems to: automatically define a set of preferences for each local computing resource that determines what information is relevant to the local computing resource; receive a document from a multicast channel; determine whether the document includes relevant information by reading published meta tags in the document for meta data, and determining whether the meta data is of interest to the local computing resource; and process the document if the document includes relevant information.
Claim 12
Dependent Claim
70 words
The article of claim 9 , wherein the sequences of instructions that cause the one or more electronic systems to determine if the document includes relevant information further comprise sequences of instructions that, when executed, cause the one or more electronic systems to: obtain a session identification associated with a request for the document; and determine whether the session identification corresponds to an active session run on a client terminal.
Claim 13
Dependent Claim
37 words
The computer-readable medium of claim 9 , wherein determining if the document includes relevant information comprises: obtaining meta data associated with the document; and determining whether the meta data is of interest to a local computing resource.
Claim 14
Dependent Claim
69 words
The article of claim 9 , wherein the sequences of instructions that cause the one or more electronic systems to determine if the document includes relevant information by reading published meta tags in the document for the meta data further comprise sequences of instructions that, when executed, cause the one or more electronic systems to determine if the document includes relevant information by analyzing the content of the document.
Claim 15
Dependent Claim
66 words
The article of claim 9 , wherein the sequences of instructions that cause the one or more electronic systems to determine whether the meta data is of interest to the local computing resource comprise sequences of instructions that, when executed, cause the one or more electronic systems to reference a local information profile to determine whether the meta data is indexed in the local information profile.
Claim 16
Dependent Claim
