| Outline of Final Research Achievements |
To achieve local location recommendation based on user's current position obtained by smart phone GPS and various locations (such as stores, tourist site, and venues) on social service, an extension of location information is proposed by using images submitted to the locations. In the location recommendation, it is quite difficult to characterize the location and users prole, because the posted texts in the social services are small in general. This paper presents the translation of images to Bag of visual words to use them instead of text information of each location. The number of images submitted to location is enough for characterize the feature of location and prole of users. Through the evaluation experiments, it is confirmed the effectiveness of the proposed method, especially, increase the coverage of recommendation.
