DEVICE FOR PROVIDING SENSITIVITY INFORMATION, METHOD THEREOF, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide sensitivity information with respect to hundreds to thousands of sensitivity expressions by extracting a predetermined co-occurrence pattern of a sensitivity expression and a pole expression on a sensitivity space from a text.

SOLUTION: A text analysis unit 1 analyzes an input text to output text analysis information; a sensitivity co-occurrence pattern extraction unit 2 extracts pole unit co-occurrence sensitivity expression information regarding sensitivity expressions which have co-occurred in a predetermined relationship with pole expressions and the number of occurrences thereof, by the use of the text analysis information, a sensitivity expression dictionary 4 registering the information of word strings representing the sensitivity expressions and a co-occurrence pattern extraction rule 5 registering co-occurrence patterns that comprise regular expressions of the word strings when a sensitivity expression and a pole expression that indicates the pole of a sensitivity axis on a sensitivity space co-occur in a predetermined relationship; and a sensitivity feature value providing unit 3 outputs sensitivity information that includes sensitivity vectors of the sensitivity expressions by use of sensitivity expression information co-occurring per pole unit.
