Multimedia network for knowledge representation
First Claim
1. A method for encoding knowledge, comprising the steps of:
- forming a network having nodes that represent semantic concepts;
associating one or more words with one or more of the nodes;
associating multimedia content with one or more of the nodes; and
representing relationships between the nodes as arcs between associated words and arcs between associated multimedia content.

Abstract
A method and apparatus for encoding knowledge using a multimedia network. A multimedia network represents semantic concepts and their relations using multimedia content. A multimedia network associates words and multimedia content with the semantic concepts in order to illustrate and exemplify the semantic concepts as well as describe lexical, semantic, and perceptual relations. The multimedia network can be searched, browsed, or summarized for purposes of information discovery. The multimedia network can also be used for personalizing multimedia content or for querying a multimedia information repository by expanding a query to include related concepts encoded in a Multimedia network.

6. A method for searching an encoded media network knowledge representation that comprises a network having nodes that represent semantic concepts, one or more words and multimedia associated with the one or more nodes, and wherein relationships between the nodes are represented as arcs between associated words and arcs between associated multimedia content, the method comprising the steps of:
-
accepting a query;
matching the query to the words and multimedia content related to the concepts encoded in the media network knowledge representation;
navigating the relationship arcs of the concepts associated with matching words and multimedia content; and
retrieving related concepts, words, and multimedia content from the matched nodes or related nodes. - View Dependent Claims (7, 8, 9)

14. A method for updating an encoded media network knowledge representation that comprises a network having nodes that represent semantic concepts, one or more words and multimedia associated with the one or more nodes, and wherein relationships between the nodes are represented as arcs between associated words and arcs between associated multimedia content, the method comprising the steps of:
adding, deleting or modifying concepts, relations, or associated words, multimedia content, or descriptors in the encoded media network knowledge representation.
-
15. A method for querying a multimedia information repository associated with an encoded media network knowledge representation that comprises an encoded network having nodes that represent semantic concepts, one or more words and multimedia associated with the one or more nodes, and wherein relationships between the nodes are represented as arcs between associated words and arcs between associated multimedia content, the method comprising the steps of:
-
searching the encoded media network knowledge representation;
retrieving words, content, and/or descriptors from the media network knowledge representation; and
searching the information repository using the retrieved words, content, and/or descriptors.

-
16. A method for personalizing multimedia information in a system comprising an encoded media network knowledge representation that includes an encoded network having nodes that represent semantic concepts, one or more words and multimedia associated with the one or more nodes, and wherein relationships between the nodes are represented as arcs between associated words and arcs between associated multimedia content, the method comprising the steps of:
-
describing the multimedia information using words or descriptors;
describing user preferences using words, multimedia content, and/or descriptors;
matching the user preferences with the descriptions of the multimedia information; and
extracting, retrieving, and/or summarizing the matched multimedia items.

17. A system for encoding knowledge, comprising:
-
means for forming a network having logical nodes that represent semantic concepts;
means for associating one or more words with one or more of the nodes;
means for associating multimedia content with one or more of the nodes; and
means for representing relationships between the nodes as arcs between associated words and arcs between associated multimedia content.

-
24. A computer program product in a computer readable medium for use for encoding knowledge, the computer program product comprising:
-
first instructions for forming a network having logical nodes that represent semantic concepts;
second instructions for associating one or more words with one or more of the nodes;
third instructions for associating multimedia content with one or more of the nodes; and
fourth instructions for representing relationships between the nodes as arcs between associated words and arcs between associated multimedia content.
