DIALOG PROCESSING SYSTEM, DIALOG PROCESSING METHOD AND COMPUTER PROGRAM
First Claim
1. A dialog processing system comprising:
- an utterance pattern input unit for inputting an utterance pattern which is an utterance structure derived from contents of field-independent general conversations;
an utterance data input unit for inputting a plurality of utterance data obtained by converting contents of a plurality of conversations in one field into a text format;
a target expression data extraction unit for extracting a plurality of target expression data from the plurality of utterance data inputted by the utterance data input unit, the target expression data each including a pattern matching portion which matches any of the utterance pattern inputted by the utterance pattern input unit;
a feature extraction unit for retrieving each of the pattern matching portions from the plurality of target expression data extracted by the target expression data extraction unit, and then for extracting a feature quantity common to some of the plurality of pattern matching portions; and
a mandatory data extraction unit for extracting mandatory data in the one field by use of the feature quantities extracted by the feature extraction unit, the mandatory data included in the plurality of utterance data inputted by the utterance data input unit by use of the feature quantities extracted by the feature extraction unit.

Abstract
A dialog processing system which includes a target expression data extraction unit for extracting a plurality of target expression data each including a pattern matching portion which matches an utterance pattern, which are inputted by an utterance pattern input unit and is an utterance structure derived from contents of field-independent general conversations, among a plurality of utterance data which are inputted by an utterance data input unit and obtained by converting contents of a plurality of conversations in one field; a feature extraction unit for retrieving the pattern matching portions, respectively, from the plurality of target expression data extracted, and then for extracting feature quantity common to the plurality of pattern matching portions; and a mandatory data extraction unit for extracting mandatory data in the one field included in the plurality of utterance data by use of the feature quantities extracted.

10. A computer program embodied in computer-readable memory comprising computer code for allowing a computer to execute the steps of:
-
inputting an utterance pattern which is an utterance structure derived from contents of field-independent, general conversations; inputting a plurality of utterance data obtained by converting contents of a plurality of conversations in one field into a text format; extracting, from the plurality of utterance data inputted, a plurality of target expression data each including a pattern matching portion which matches the inputted utterance patterns; retrieving the pattern matching portions, respectively, from the plurality of target expression data extracted, and then extracting a feature quantity common to the plurality of pattern matching portions; and extracting mandatory data in the one field included in the plurality of utterance data inputted by use of the feature quantities extracted.

11. A dialog processing method comprising the steps of:
-
inputting utterance patterns which are utterance structures derived from contents of field-independent, general conversations; inputting a plurality of utterance data obtained by converting contents of a plurality of conversations in one field into a text format; extracting a plurality of target expression data including pattern matching portions which match the inputted utterance patterns from the plurality of utterance data inputted; retrieving the pattern matching portions, respectively, from the plurality of target expression data extracted so as to extract feature quantities common to a plurality of the pattern matching portions; and extracting mandatory data in the one field included in the plurality of utterance data inputted by use of the feature quantities extracted.
