We present the No-SQL based Web service system for sharing of emotion information regarding the individual emotional states and location information of users using by a MongoDB in cloud computing environments. Pre-processed emotion information represents the individual emotional states categorized as a nine domain based on physiological signals recognition within the database system. However, in order to present individual emotional states regarding to pre-processed user’s emotional states and locations on a Web-based map, the computational overload with large amount of data for a location-query process is to be solved for support sharing Web services. Meanwhile, previous RDBMS-based systems are inadequate due to insufficient scalability and processing time of data processing nodes. Therefore, in this paper, we have designed and implemented an emotion sharing web service by reducing the load on the system using NoSQL database. In addition, it was confirmed that it is possible to effectively utilize resources and visualized by using Google’s FusionTable and it is possible to share on a Web map.
