Development of Reliable Advanced Inter-operable Agent Technology on Web Service Composition

在这项研究中，我们的目标是开发的代理系统，这是可靠的和高度的互操作性。我们朝这个方向发展了基础技术。主要结果如下。(1)We通过在推测计算失败时引入备份操作，推进了我们以前对推测计算的研究。(2)We制作了一个执行上述备份操作的原型系统。我们使用以前开发的业务支持系统，该系统预测用户的酒店，而系统搜索的运输行程和系统进行初步预订。当用户进行酒店预订时，如果预订与系统预测相同，则预订变为真实的，否则系统取消临时预订并进行用户的预订。我们表明，如果一个投机行为是不可撤销的，我们可以使用相同的技术一般。(3)We开发了一种方法来集成不同的本体与维护的一致性。（4）利用语义Web技术，开发了一个基于RDF信息的Web内容解释系统。我们还开发了一个语义WIKI系统，以支持生产这样的RDF信息。(5)We开发了一个通过关联粗粒度任务本体、中粒度Web/应用/手工本体和可执行程序自动生成复杂工作流的系统。本文还提出了本体构建支持工具DODDLE来支持上述本体构建。

In this research we aim at development of agent systems which is dependable and highly inter-operable. We developed basic technology toward this direction. The main results are as follows.(1)We advanced our previous research of speculative computation by introducing back-up action when speculative computation fails.(2)We made a proto-type system which performs the above back-up action. We used previously developed business support system where the system predicts user's hotel while the system searches a transportation itinerary and the system makes a tentative reservation. When the user makes a hotel reservation, if the reservation is the same as the system prediction, the reservation becomes genuine otherwise the system cancels a tentative reservation and makes a user's reservation. We show that if a speculative action is undoable, we can use the same technique in general.(3)We developed a method to integrate different ontology with maintenance of coherency.(4)Using semantic-web technology, we developed a system which explains web contents using RDF information. We also developed a semantic WIKI system to support producing such RDF information.(5)We developed a system which automatically produces complex workflow by associating coarse-grained task ontology, medium-grained web/application/handwork ontology and executable programs. We also advanced ontology construction support tool DODDLE to support the above ontology construction.
