Abstract
A computer-implemented method, system, and computer program product for generating a synonym list from an existing thesaurus includes preparing a first feature vector from a natural language query and preparing a second feature vector from a result of the natural language query, determining, using a processor, whether a combination of a first feature from the first feature vector and a second feature from the second feature vector is included as a synonym pair in the existing thesaurus, and generating the synonym list by adding the combination to the synonym list when the determination is positive. The result of the natural language query may be identified by a user browsing action or by a positive feedback from a user. The method further includes reading a log which includes a single set or plural sets of the natural language query and the result of the natural language query.
