Field trial evaluation of a location-aware social capital service

Abstract

We have been studying a service coordination technology that enables users to use the various types of service elements that are available in a ubiquitous computing and networking environment. We have adopted a user context handling mechanism to choose suitable service components. In this paper, we proposed an adaptive information delivery method for personalized recommendation and information provisioning. This method can provide information services based on user location, preferences, or moving history to everyone, everywhere, using a mobile phone. This system is an information circulation system based on social capital, which refers to connections between social networks. Users can obtain information about events, sightseeing information, gourmet information, disaster prevention information from SNS by marking the location information. We also applied a location-dependent recommendation method based on user's movement history. We conducted a field trial to evaluate feasibility of the system. According to the results of our questionnaire, the information-provision style is acceptable to the users. In addition, according to the analysis of the user movement and user preferences, there was a correlation between user's visited place and interested genres.
