Geo-local contents system with mobile devices

Abstract

This paper investigates the quality of geographical information provided by Geo-media, such as Foursquare, and its geographical distribution. According to the result, geographical information described by autonomous individuals contains numerous errors and lacks data, even though it tends to have detailed street addresses. In addition, the information is heavily clustered in metropolitan areas. In order to reduce the errors, lack of data, and geographically-biased distribution of information, geo-local content systems have been developed with mobile devices for people in local communities. Members of a local community, e.g., shopping districts and tourist spots, have strong incentives to provide high quality information to their customers. Hence, the systems are provided to people in these communities so that a vast amount of geo-local contents is going to be published on the Internet.
