METHODS AND APPARATUS FOR ENTITY DETECTION
First Claim
Patent Images
1. A method comprising:
- matching a token from at least a portion of a text string with a matching concept in an ontology;
identifying a first concept as being hierarchically related to the matching concept within the ontology;
identifying a second concept as being hierarchically related to the first concept within the ontology;
including the first and second concepts in a set of features of the token; and
determining, using at least one processor, a measure related to a likelihood that the at least a portion of the text string corresponds to a particular entity type, based at least in part on the set of features of the token.

Abstract
Techniques for entity detection include matching a token from at least a portion of a text string with a matching concept in an ontology. A first concept may be identified as being hierarchically related to the matching concept within the ontology, and a second concept may be identified as being hierarchically related to the first concept within the ontology. The first and second concepts may be included in a set of features of the token. Based at least in part on the set of features of the token, a measure related to a likelihood that the at least a portion of the text string corresponds to a particular entity type may be determined.

9. Apparatus comprising:
-
at least one processor; and at least one processor-readable storage medium storing processor-executable instructions that, when executed by the at least one processor, perform a method comprising; matching a token from at least a portion of a text string with a matching concept in an ontology; identifying a first concept as being hierarchically related to the matching concept within the ontology; identifying a second concept as being hierarchically related to the first concept within the ontology; including the first and second concepts in a set of features of the token; and determining a measure related to a likelihood that the at least a portion of the text string corresponds to a particular entity type, based at least in part on the set of features of the token. - View Dependent Claims (10, 11, 12)

13. At least one computer-readable storage medium encoded with computer-executable instructions that, when executed, perform a method comprising:
-
matching a token from at least a portion of a text string with a matching concept in an ontology; identifying a first concept as being hierarchically related to the matching concept within the ontology; identifying a second concept as being hierarchically related to the first concept within the ontology; including the first and second concepts in a set of features of the token; and determining a measure related to a likelihood that the at least a portion of the text string corresponds to a particular entity type, based at least in part on the set of features of the token. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
