Abstract:
1. A request content identification system for analyzing a request sentence (input request sentence) inputted in a natural language format and identifying a request content, comprising: a generating unit configured to generate audio recognition result candidates by performing an audio recognition process for an audio-inputted input request sentence; a performing unit configured to perform a syntax analysis for each audio recognition result candidate of said input request sentence by employing a common rule for the syntax analysis that does not depend upon the request content, and request-unique rules for the syntax analysis unique to each request content; a score computing unit configured to calculate, for each of the audio recognition result candidates, an integration score obtained by combining an audio recognition score and a syntax analysis score for each request-unique rule employed in the syntax analysis; and an identifying unit configured to identify the request content corresponding to the request-unique rule employed in the syntax analysis having a highest integration score as a request content corresponding to said inputted request sentence.
