Research and Development of Intelligent Groupware using Situated Agents

研究的目的是，首先克服目前信息处理系统的缺点，同时预见随着新世纪的到来将进一步出现的问题，最后创造一个即使不是最好的也可以优雅地解决这些问题的环境。每当信息系统的任何部分发生变化时，灵活的计算环境都应该能够智能地、自平衡地和进化地吸收它。构建这种环境的关键概念之一是使用一个情境代理来观察它的环境，如其他代理、它的用户以及网络和计算资源。情境智能体可以根据其所处环境的状态灵活地改变其行为。它可用于构建信息网络上的协同工作支持环境。本文的研究成果基于情境智能体，总结如下。协作工作的计算形式化：人与人之间的协作工作是使用DELIS-分散化的LISP解释器中指定的情境代理来表示和形式化的。协同工作空间的构建：情境代理被实现为DELIS的应用程序。它们被用来构建协同工作空间这一高级群件。应用软件的实现：在协同工作空间中实现了各种协同工作支持工具。通过使用它们对它们进行了评估。

The purpose of research is to, first overcome the drawbacks of present day information processing systems, and at the same time to foresee the problems that would further sprout with the coming of the new century, and finally to create an environment which could solve those problems in a graceful way, if not optimally. Whenever a change occurs in any part of the information system, the flexible computing environment should be able to absorb it intelligently, homeostatically, and evolutionarily. One of the key concepts of constructing such environment is to use a situated agent which observes its environment such as the other agents, its user, and network and computing resources. Depending on the status of its environment, the situated agent can change its behavior flexibly. It can be used to construct a cooperative work support environment on the information network.The research results are based on the situated agent and summarized as follows.1. Computational formalization of cooperative work : Cooperative work among people was expresed and formalized using situated agents which were specified in DeLis-Decentralized Lisp Interpreter.2. Construction of cooperative work space : Situated agents were implemented as applications of DeLis. They were used to construct cooperative work space which was a kind of advanced groupware.3. Implementation of application software : Various cooperative work support tools were implemented in the cooperative work space. They were evaluated through their use.
