| Outline of Final Research Achievements |
In these days, people post geo-social data with time and location information on social media. These posts include things that people are witnessing and they are related to real comments in the real world. Geo-spatial data including time, location and content is called geo-spatial social data. In this study, we have developed spatio-temporal data mining techniques for geo-spatial social data. These spatio-temporal data mining techniques enable us to know what is happing, when the things are happing, where the things are happing, how things are changing. We can use geo-spatial social data as an information source by using spatio-temporal data mining techniques for geo-spatial social data.
