1. Tomoaki Imajo, Kazutoshi Sumiya, Taketoshi Ushiama, An SNS Based on Implicit Beneficial Social Relations in A Regional Community, Proceedings of the 10th International Conference on Ubiquitous Information Management and Communication, 2016.01, In this paper, we propose a novel Social Networking Service (SNS) for a regional community. The purpose of the SNS is to support and encourage people by making them aware beneficial social relations in the real world. The conventional SNSs can hardly deal with beneficial social relations, because they are implicit and dynamic. The proposed SNS is designed to provide positive information for two types of people: people who does community voluntary works, such as cleaning, as contributors, and people who receives benefit from them as beneficiary. This paper introduces the basic scheme based on the SNS for beneficial social relations, and evaluates the effectiveness of our scheme based on the result of the experimental studies. The experimental result shows the users of our SNS tend to consider the information about the voluntary works valuable if they have been performed in their living area, and it suggests that our proposed SNS system would work well in a regional community..

Taketoshi Ushiama, Noboru Matsuo, A method for finding similes to support final selection from search results, Proceedings of the 9th International Conference on Ubiquitous Information Management and Communication, 10.1145/2701126.2701197, Article No. 59 , 2015.01, This paper introduces a method for supporting users to select the final object(s) from the results of search/recommendation. In order to realize the purpose, our method provides the user with similes that would make the user understand the characteristic features of a pair of objects easily and quickly. In order to search suitable similes, we introduced the difference feature vector for a pair of objects. The difference feature vector emphasizes the differences of the objects in the pair and downplays the common features, because objects in a search/recommendation result set have the common features that matched the search/recommendation conditions and the common features are useless for further selection. The effectiveness of the proposed method is evaluated based on the experimental user studies and it is shown that our method can search more adequate simile pairs for the given pair of objects than the baseline method based on the simple feature vectors..
3. Hon Yan, Taketoshi Ushiama, Effective Browsing Technique based on Behavioral Collaborative Filtering on Social Streams, Knowledge-Based and Intelligent Information & Engineering Systems 18th Annual Conference, KES-2014 Gdynia, Poland, September 2014 Proceedings, 10.1016/j.procs.2014.08.263, 35, 1702-1710, 2014.09, n recent years, Social Networking Services (SNSs) are growing in popularity, and generating new articles moment by moment. However, when huge article streams are delivered from the SNS, it is not easy to browse them efficiently because users would sometimes skip valuable articles. In this paper, we propose a method to recommend an unread article in order to achieve efficient browsing. Our method estimates the preference of a user on a delivered article based on the browsing behavior of the user, and predicts the preference of each unread article based on the collaborative filtering approach. Our system estimates the value of each unread article for the target user based on the behaviors of users who might be highly similar to the target user's behavior of reading articles, and utilizes the estimation results for composing unread articles into a stream in an appropriate order to realize efficient browsing..
