Automatic Collection and Visualization of the Expressions that Represent Changes of Situations in the Society

Abstract

In this paper, we discuss automatic collection and visualization of the expressions that represent changes of situations in our society. In creating new products or making a new plan, it is necessary to grasp the change in social situation. There are various ways in which we may find changes of situation in our society. For some of them, such as statistical manners, we have to begin with discussion of how to interpret them. We focus on expression on Web documents that seem to be written as authors' own interpretation of chages of situations in our society. We propose a method to collect them automatically from the Web documents. We also discuss a visualization method to help users to understand the collected expressions easily.
