As our early work, we proposed a data mining model for query refinement using Association Rules (ARs) mined among keywords of a large document database. In this paper, first, we explicitly identify principles of a data mining model for query refinement, and show that our model satisfies the principles. Second, we propose a mechanism to reduce the large number of ARs using a concept called "prime keyword". The effectiveness of our approach will be discussed. Considering the fact that most of today's searching engines on the Internet are keyword based, our approach can be easily extended to support Web applications.
