| Outline of Final Research Achievements |
This study aims to develop a feature construction method from complex dataset, which consist of not only numerical and nominal values but also their temporal values. However, conventional feature extraction methods have been only developed for each kind of values for constructing features for performing some statistical methods and machine learning methods.
In this study, existing importance evaluating indices from the natural language processing field and sequential pattern evaluation indices were formulated to an integrated viewpoint for evaluating sequential patterns. Then, by combining these indices with temporal pattern extraction method, the method has enable to extract temporal causalities for understanding user behaviors on Web clickstream and temporal text corpus on SNS from more data-centric viewpoint.
