Information processing apparatus and information processing method

An information processing method, comprising:

• in an formation processing apparatus:
• acquiring a structure of a query sentence by analysis of the query sentence and a structure of a target document by analysis of the target document, wherein the target document is a result of a search based on at least one search word in the query sentence;
• determining an answer candidate based on:
• a comparison of the structure of the query sentence and the structure of the target document,
• a determination that a plurality of grammatical cases of the structure of the query sentence is identical to a plurality of grammatical cases of the structure of the target document at a determined rate;
• generating information to present the determined answer candidate in association with the structure of the query sentence;
• and
• calculating a score that indicates a commensurate degree as an answer for each determined answer candidate of a plurality of determined answer candidates, the score is further based on a satisfaction degree that is fed back for a previous answer that is presented to the same query sentence, with respect to each determined answer candidate of the plurality of determined answer candidates.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:

• acquiring a structure of a query sentence by analysis of the query sentence and a structure of a target document by analysis of the target document, wherein the target document is a result of a search based on at least one search word in the query sentence;
• determining an answer candidate based on:
• a comparison of the structure of the query sentence and the structure of the target document which, and
• a determination that a plurality of grammatical cases of the structure of the query sentence is identical to a plurality of grammatical cases of the structure of the target document at a determined rate;
• generating information to present the determined answer candidate in association with the structure of the query sentence;
• and
• calculating a score that indicates a commensurate degree as an answer for each determined answer candidate of a plurality of determined answer candidates, the score is further based on a satisfaction degree that is fed back for a previous answer that is presented to the same query sentence, with respect to each determined answer candidate of the plurality of determined answer candidates.
