Abstract(in English) | It is important to promote Evidence-Based Policy Making (EBPM) to conduct effective tourism policies with unique tourism resources. We are developing an EBPM platform that visualizes people flows relating to events and tourism policies. Our EBPM platform has an automatic event detector that detects ``where'' and ``how large'' an event is held. When an event is detected, the platform notifies local government officers and encourages them to enter the event information to link the event and corresponding people flow. Although, we can use anomaly detection methods to detect events from people flow data, these methods take no considerations on periodic changes in people flow. In this paper, a new feature, i.e., location activeness, is defined as time-series people flow data, excluding periodic changes. We also present an event detection method base on peak detection on the location activeness. The evaluation conducted with location data of Kyushu University Ito Campus and surrounding areas demonstrated that more than 75% of detected events were actual events, as we could find out. |
