A Method for Retrieving Knowledge from Repositories of Distributed Integrated Information System |
| |
| Abstract: | ： The repositories are the kernel of distributed integrated information system for product design,The efficiency and reality of knowledge retrieve have great effect on the performance of system.Base on artificial neural networks,fuzzy logic and rule reasoning,a method for retrieving knowledge from repositories is proposed.And the issue on how to layer the knowledge is discussed.Take the determination of support parts types as an example,a prototype of knowledge retrieve is developed.The aim is to seek an efficient and reliable method of retrieving knowledge from repositories to support the running of distributed integrated information system for product design successfully. |
