Title:
SENSITIVITY ANALYSIS SYSTEM AND PROGRAM
Document Type and Number:
Japanese Patent JP2012256283
Kind Code:
A
Abstract:

To present a study sentence which expresses the described content of each sentence at the point of time in a straight-forward manner when an analysis is made from a time sequence point of view for the aggregate of sentences whose number is exponentially increasing and decreasing.

A sensibility analysis system 10 includes: a negative/positive determination part 14 which gives a negative/positive polarity tag to a sensibility term and gives a negative expression tag to a negative expression of each sentence and gives a negative/positive determination tag to the sensibility term and the negative expression based on the type of polarity tag and the presence or absence of the negative expression tag; an emotion extraction part 18 for associating an emotion type tag with an emotion expression of each sentence; a study rule storage part 24 for storing a plurality of study rules; and an analysis result estimation part 21 for generating a time sequence change graph by adding up the number of sentences every day based on date information of each sentence, applying each study rule to an aggregate of sentences within a prescribed period of interest including change points on the graph and the aggregate of the sentences within all the periods, extracting a template on the study rule which matches only the aggregate of the sentences within the period of interest as the study sentence relating to the change point and outputting it together with the time sequence change graph.
