Method and system for semantic search and retrieval of electronic documents

A computer implemented method for semantic search for electronic documents stored on a computer readable media, and providing a search result in response to a query, comprising:

• providing a corpus including a plurality of electronic documents that are tagged at a document level to identify general domain of each electronic document, and are analyzed based at least partially on said tags to identify word usage patterns in said plurality of electronic documents;
• providing an index of word usage patterns that indexes said plurality of electronic documents in said corpus according to word usage patterns and said domain tags of said plurality of electronic documents;
• receiving a query from a user;
• analyzing said query to derive probable word usage patterns in said query;
• using said index to identify at least one of said electronic documents that has word usage patterns matching said probable word usage patterns in said query as a candidate electronic document;
• and
• retrieving said candidate electronic document.

A system for semantic search for electronic documents stored on a computer readable media, and providing a search result in response to a query, comprising:

• a corpus of a plurality of electronic documents;
• a tagging module that tags said plurality of electronic documents in said corpus at a document level to identify general domain of each electronic document;
• a word usage module that determines word usage patterns in said plurality of electronic documents in said corpus based at least partially on said tags of said plurality of electronic documents;
• and
• an indexing module that indexes said plurality of electronic documents in said corpus at least according to word usage patterns and domain tags.

A computer readable medium with executable instructions for semantic search for electronic documents stored on a computer readable media, and providing a search result in response to a query, comprising:

• instructions for receiving a query from a user;
• instructions for analyzing said query to derive probable word usage patterns in said query;
• instructions for accessing an index of word usage patterns that indexes a plurality of electronic documents according to word usage patterns in said plurality of electronic documents, said plurality of electronic documents being tagged at a document level to identify general domain of each electronic document;
• instructions for identifying at least one of said electronic documents that has word usage patterns matching said probable word usage patterns in said query as a candidate electronic document;
• and
• instructions for retrieving said candidate electronic document.
