One of the important features of expert systems is to provide explanations suitable to the user's needs. Thus it is desirable to construct an expert system which can flexibly give explanations to different levels of users. Many existing expert systems are only designed for one type of user. In this work, using the Designer's Assistant system as the platform, we build up the user modelling and text retrieval components so that the system can adapt to different levels of the user's expertise. In the implementation, a model is built for each user using the system based on his/her expertise, goals, needs, etc. Text documentation is retrieved for a particular user based on his/her model and is used as explanations. The result is that different explanations are provided for different users, depending on their needs.Dept. of Computer Science.
