Knowledge transaction processing is a very new research area in mobile environments. The main goal of this chapter is to explore and study knowledge representation, reasoning, and transactions in mobile environments. As the outcome of the discussion, this chapter presents and formalizes a knowledge transaction language and model for use in mobile computing environments. In addition, this resear...

Application experts need to be able to maintain, populate, and verify existing knowledge bases in order to use knowledge-based tools to perform their daily tasks. Protégé-2000 is a tool that enables experts to perform the knowledge-acquisition and maintenance process. In this paper, we describe a controlled study that we performed to measure both the efficiency and quality of knowledge acquisit...

With the development of network technology, distance education is becoming increasingly important. Intelligent question answering system is an important part of remote learning system. Currently, there have been a lot of mature English question answering systems. Owing to the Chinese natural language complexity and processing technical limitations, there is still no mature Chinese QA system exp...

Selection of Commercial-off-The-Shelf (COTS) software products is a knowledge-intensive process. In this paper, we show how knowledge bases can be used to facilitate the COTS selection process. We propose a conceptual model to support decision makers during the evaluation procedures. We then describe how this model is implemented using agent technologies supported by two knowledge bases (KB): t...

This paper introduces, motivates, and illustrates an approach to the construction of intelligent assistance systems that we call collaborative manipulation. We show how a system can offer effective assistance through collaborative manipulation of objects in a shared workspace. We have developed this approach through experience with an intelligent knowledge editing tool, the HITS Knowledge Edito...

Virtual agents are used by the military for extensive training of pilots. However, creating virtual agents with the appropriate behaviors is a lengthy and specialized process. We describe a new tool (TAF) to allow rapid creation of virtual adversarial agents by non-specialized personnel. In TAF, users can draw diagrams of agent behavior which are matched within a pre-existing knowledge base. By...

This paper describes the implementation of an argumentation system used for participatory management of environmental protected areas, more precisely to model the decision of a park manager artificial agent. This implementation is based on a BDI agent architecture, namely the Jason/AgentSpeak framework/language. After introducing the principles of BDI architecture and of argumentation systems, ...

Patents are an important source of technological intelligence that companies can use to gain strategic advantage and computational patent mapping is a methodology for the development and application of a technology knowledgebase for technology and competitive intelligence. The primary deliverables of patent mapping is in the form of knowledge visualization through landscape and maps. This paper...

The integration of an assertion stemming from some sender agent into the knowledge base of a receiver agent may be hindered by logical incompatibilities. In the belief-revision scenario the receiver agent trusts the incoming assertion and starts a revision of his knowledge base— resulting in the elimination of some formulas of the knowledge base. In this paper a new family of belief-revision op...
