A problemsolving strategy is presented in which decision-support and knowledge-based techniques play complementary roles. An approach to the representation of knowledge to support the problem-solving strategy is presented which avoids commitment to a specific programming language or implementation environment. The problem of choosing a home is used to illustrate the representation of knowledge in a specific problem domain. Techniques for implementation of the problem-solving strategy are described. Knowledge elicitation techniques and their implementation in a development shell for application of the problem-solving strategy to any selection problem are also described.展开更多

A kind of united knowledge representation model, which can include ma ny sorts of knowledge carriers and knowledge representation methods, was advance d firstly, and then mechanical knowledge XML tag was designed based on it. Thus, knowledge still stay in primary electronic document, and knowledge document bec ome document knowledge base based on Web with hierarchy. A corresponding method was advanced and a knowledge acquisition system was developed. It can understand user’s questions in natural language and then find the relevant knowledge and execute reasoning and answer the user’s questions according the result of reaso ning and realized the automatic knowledge acquisition from Web knowledge documen t.展开更多
