Research Abstract

We have systemized knowledge about events useful for analyzing causal relationships and helping judgments of information credibility. The summary of our work is the following (1)-(3) : (1) Time graph pattern mining methods for analyzing propagation of eventual knowledge. (2) A model of eventual knowledge and a method of extracting eventual knowledge. (3) A method for computing the strength of the relationship between two objects and obtaining objects elucidating the relationship. We have also applied ideas used in this method to helping a user to judge the credibility of an image on Wikipedia.
