Question-answering method and question-answering apparatus
First Claim
1. A program for a question-answering apparatus having a communication equipment for receiving an input of a question document, a storage for storing a plurality of reply examples and a CPU for performing a reply composition process of replying to the question document by using a reply example selected from the plurality of reply examples, the program executing steps of:
- extracting a plurality of important areas from said input question document;
combining said plurality of important areas to one or a plurality of important parts in accordance with a reply example candidate likelihood value of said plurality of reply examples obtained for each of said plurality of important areas; and
obtaining a reply example candidate corresponding to said important part by using the plurality of stored reply examples.

Abstract
A question document is divided into predetermined areas, and it is judged whether each divided area is important, to thereby extract an important area. A reply example candidate likelihood value is calculated for each important area, the likelihood value indicating the degree representative of whether each reply example candidate corresponds to a question content. By using the reply example candidate likelihood value, important areas having similar meanings are combined to extract final important parts. A reply example candidate is selected for each important part from reply example candidates prepared beforehand. A reply example candidate reliability degree representative of certainty of each reply example candidate and a reply composition degree indicating whether it is necessary to compose a new reply are calculated, and by using these values, question documents are distributed to different operator terminals.

12. A question-answering system having a question-answering apparatus and a reply composition terminal combined via a network to said question-answering apparatus, wherein:
-
said question-answering apparatus comprises a communication equipment for receiving an input of a question document, a storage for storing a plurality of reply examples and a processor unit for performing a reply composition process of replying to the question document by using a reply example selected from the plurality of reply examples;
said reply composition terminal comprises a communication apparatus for receiving a result of said reply composition process, a display for displaying information contained in said reply composition process result and an input unit for receiving an input for said display information; and
the processor unit of said question-answering apparatus extracts a plurality of important areas from said input question document, combines said plurality of important areas to one or a plurality of important parts in accordance with the reply example candidate likelihood value of said plurality of reply examples obtained for each of said plurality of important areas, and obtains a reply example candidate corresponding to said important part by using the plurality of stored reply examples to output said reply composition process result. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
