<p><P>PROBLEM TO BE SOLVED: To provide a talk evaluation technique for deriving an evaluation function with a higher-than-conventional performance. <P>SOLUTION: Talk data of each talk regarding each of plural users is stored in a talk data storage part 1. A statistic extraction part 2 calculates the average value of the number of predetermined utterances in a talk of each of the plural users and the average value of talk lengths from the talk data, and extracts a statistic constituting an explanatory variable of an evaluation function from the talk data. A clustering part 3 clusters plural users based on the calculated average value of the number of predetermined utterances in the talk and on the calculated average value of the talk lengths. An evaluation function derivation part 4 derives an evaluation function corresponding to an individual cluster by means of a multiple regression analysis using a statistic related to a user included in the individual cluster as explanatory variable and a user evaluation value as response variable. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
