Luo Min · Journal of Hefei University of Technology · 2001
In this paper, the method of calculating the similarity degree between the new problem and similar case is discussed. This method is used to retrieve the most similar case in the similarity case database.The rough set theory is applied to find out the redundant feature attributes and calculate the importance degree of each feature attribute. The results objectively reveal the similarity degree between the new problem and similar case, and the accuracy of case retrieval is improved.
