QUERY DISAMBIGUATION IN A QUESTION-ANSWERING ENVIRONMENT
First Claim
1. A computer-implemented method of query disambiguation in a question-answering environment, the method comprising:
- identifying, using a first natural language processing technique, a first set of word clusters in a first candidate answer generated in response to a first input query for a question-answering system, the first set of word clusters including a first word cluster, each of the first set of word clusters classified according to a syntactic element of a first set of syntactic elements;
identifying, using the first natural language processing technique, in the first input query, a second set of word clusters, each of the second set of word clusters classified according to a syntactic element of a second set of syntactic elements;
determining, by comparing the first and second sets of syntactic elements, that the first word cluster is classified according to a first syntactic element that is not present in the second set of syntactic elements; and
generating, using a second natural language processing technique, a second input query using the first input query and the first word cluster.

Abstract
Query disambiguation can include identifying, a first set of word clusters in a first candidate answer generated in response to a first input query for a question-answering system. Each of the first set of word clusters can be classified according to a syntactic element of a first set of syntactic elements. Query disambiguation can include identifying, in the first input query, a second set of word clusters. Each of the second set of word clusters can be classified according to a syntactic element of a second set of syntactic elements. Query disambiguation can include determining that the first word cluster is classified according to a first syntactic element that is not present in the second set of syntactic elements and generating a second input query using the first input query and the first word cluster.
