SEARCH ENGINE DETERMINING RESULTS BASED ON PROBABILISTIC SCORING OF RELEVANCE
First Claim
1. A method for creating semantically relevant, ranked search results, the method comprising:
- receiving an assignment of an occurrence of a term within a document to an ontological node based on usage of the occurrence of the term within the document;
determining an accuracy value associated with the received assignment by comparing the received assignment with a baseline assignment;
determining a consistency value associated with an assignor based on a repeatability of a plurality of assignments by the assignor;
determining an assignor relevance score for the assignor by statistically combining the determined accuracy value and the determined consistency value;
determining an overall semantic relevance value for the occurrence of the term by statistically combining the assignor relevance scores determined for a plurality of assignors;
ranking the document based on the determined overall semantic relevance value; and
presenting the ranked documents in response to a search request including a keyword associated with the ontological node.

Abstract
A method of providing semantically relevant, ranked search results is described. An assignment of an occurrence of a term within a document to an ontological node is received based on usage of the occurrence of the term within the document. An accuracy value associated with the assignment is determined by comparing the assignment with a baseline assignment. A consistency value associated with an assignor is determined based on a repeatability of a plurality of assignments by the assignor. An assignor relevance score for the occurrence of the term is determined by statistically combining the accuracy value and the consistency value. An overall semantic relevance value for the occurrence of the term is determined by statistically combining the assignor relevance score determined for a plurality of assignors. The documents are ranked based on the overall semantic relevance value and presented in response to a search request.
