A Directory Server for Mobile Agents Interoperability.
ABSTRACT This paper reports a directory server in a distributed middleware for realizing the interoperability between a wide variety of mobile agent systems. The ODP trader, an ITU-T recommendation for direction service, is customized for the specific requirements. The key ideas are (1) to extend the managed information so that program codes can be members, and (2) to provide Proxy Offer for utilizing services located outside the directory. Performance measurement shows that Proxy Offer is more efficient than dynamic property of the ODP trader in the current application

ABSTRACT: リサーチレポート（北陸先端科学技術大学院大学情報科学研究科） A new scenario-based object-oriented modeling method is proposed. It incorporates a semi-formal intermediate design notation GILO (Generic Interaction Language for Objects) that provides essential ingredients to represent scenario. GILO, being influenced by algebraic specification techniques, has well-defined syntax and semantics, and the modeling method is more rational than existing scenario-based modeling methods. Further, GILO descriptions can be translated into modules written in CafeOBJ, an algebraic logic language. CafeOBJ has clear semantics based on hidden order-sorted rewriting logic and descriptions can be executable. In order to show how the proposed modeling method is applied, a concrete case study on a standard design benchmark problem (the SAKE Warehouse problem) is presented. The resultant design artifact, which confirms to scenario-based object-oriented modeling method, is executable and validated in a rapid-prototyping manner with CafeOBJ.

ABSTRACT: To achieve cooperative problem solving for use in providing human activity surrogates and supporters, various agents have been designed and developed using many agent platforms. Generally, realizing cooperation or construction remains as a difficult problem confronting agent organizations using different agents running on a heterogeneous agent platform, in contrast to similar agents running on a homogeneous platform. To overcome that problem, a systematic method to construct an organization with different agents on a heterogeneous agent platform is proposed.Proceedings of the 8th IEEE International Conference on Cognitive Informatics, ICCI 2009, June 15-17, 2009, Hong Kong, China; 01/2009
