Overview

We generate advanced technologies for Internet-based worldwide collaboration. Technically, our research area lies on 1) Global Expansion of Collaboration Infrastructure, and 2) Design of Network Economy. At the same time, we develop the information system contributing the society.

Global Expansion of Collaboration Infrastructure

(Professor: ISHIDA Toru, Assistant Professor: LIN Donghui)

This group aims at generating advanced technologies for Internet-based worldwide collaboration. Based on artificial intelligence and human interface as foundations, we address latest technological challenges of services computing and Internet of Things (IoT) to realize the interaction between various cloud services on the Internet and the physical world where we live in. Moreover, we conduct global research activities with researchers in the US, Europe and Asia to promote the Language Grid, a multi-language service infrastructure we have developed for supporting intercultural collaboration.

Research Topics

  1. Language Grid: This group aims at generating advanced technologies for Internet-based worldwide collaboration. Based on artificial intelligence and human interface as foundations, we address latest technological challenges of services computing and Internet of Things (IoT) to realize the interaction between various cloud services on the Internet and the physical world where we live in. Moreover, we conduct global research activities with researchers in the US, Europe and Asia to promote the Language Grid, a multi-language service infrastructure we have developed for supporting intercultural collaboration.
  2. Services Computing/Internet of Services (IoS): We conduct the research on advanced technologies for IoS infrastructure that freely enables the composition of smartphone applications and cloud services on the Internet. In particular, our research results on service composition based on QoS (Quality of Service) and self-organization of service networks have been accepted numerous times by top international conferences. Moreover, IoS technologies are the foundations of the Language Grid.
  3. Internet of Things (IoT): To realize the interaction between people and things, we focus on the IoT environment that is driven by various sensors and fabrications. By connecting IoS and IoT seamlessly, we aim at realizing the unique collaboration environment where various things communicate with each other.
  4. Multiagent Systems: A device or software with autonomous intentions can be regarded as an agent. Multiagent system is a system where multiple agents coordinate and compete with each other, which is an essential research topic in the area of artificial intelligence. We focus on the research of theories and algorithms for multiagent as foundations of IoS and IoT.

Our projects involve wide collaboration with NPOs for international activities, and our research results make direct contributions to society. We have been supporting multilingual commutation in international symposiums and workshops for youths organized by NPOs. We are planning to provide multilingual support for foreign travelers as well by utilizing IoS and IoT. To realize our research objectives, we also cooperate with Kyoto University Design School to obtain skills for design workshop and design fabrication.

Design of Network Economy

(Associate Professor: MATSUBARA Shigeo)

This Group aims to generate advanced technologies for Internet-based worldwide market. Re-centralizing humans, goods, services distributed in the world adds a new value. To enjoy such benefit and realize smooth trade, we need to develop appropriate incentive design, i.e., mechanisms for inducing users’ participation and retention. Based on ICT and economics, especially, artificial intelligence and the game theory, we conduct global research activities by introducing the latest technologies including crowdsourcing, auction, and gamification.

Research Topic

  1. Crowdsourcing: By considering crowdsourcing as problem-solving by forming an organization of workers, we study methods for task and reward design that realize the right person in the right place. We tackle various issues from developing algorithms to developing tools for crowdsourcing.
  2. Auction: To realize efficient and safe trade, we take a game-theoretic approach to designing robust auction mechanisms. By analyzing the bidding behaviors based on the real data of Internet auctions and advertisement auctions, we have developed methods for supporting bidders.
  3. Gamification: Gamification is to apply game-design elements to a target in the non-game context and encourage users’ participation and retention. We analyze the principle of users’ behaviors in Stack Overflow that is a Q&A community for programming, and design point/badge systems that yield a lively Q&A community.

    In addition to the above projects, we conduct research on various topics including voting systems, prediction markets, reputation systems by modeling the targets from a viewpoint of incentive design and applying AI techniques such as machine learning, evolutionary computing.
