摘要

This paper examines geographical bias on social media and develops a geo-local contents system with mobile devices. Because of the maturations of GPS devices and application software, vast amount of people generate various types of contents with geographical information. However, information outside of metropolitan areas seems to be scarce because of population, even though, it is necessary to attract tourists to local areas. To clarify the geographical biases, information posting behavior on Foursquare, which is one of the famous location services, was analyzed. Moreover, geographically local contents system was developed with mobile devices in order to support creation of local contents by local community members and to reduce the geographical biases. In order to find what kind of information must be created with the system, information available on the web was collected automatically concerning two areas, i.e., a rural town and a mid-size city. According to the analysis of the collected information, the local community members have to provide more information concerning entertaining places to attract tourists.
