Abstract:

This paper presents a method for semantic Information Retrieval(IR) which is implemented on Digital Library. It is well known that Digital Library should have the IR system that user may automatically access every kind of media from anywhere. However, no improvement is made for the retrieval errors based on individual differences of user's request. This is one of the significant problem for the searching efficiency of IR. Our approach does not use the request itself but the concepts. This makes it possible to retrieve semantic information not merely to compare with the word strings of the request.
