Method of determining case feature weight based on knowledge entropy theory

摘要

Determining case feature weight is an key problem in the similarity measure of case. The traditional method for determining case feature weight usually has disadvantages such as poor objectivity and high complexit. A new method based on knowledge entropy is introduced by researching conception of knowledge entropy and measurement way, analyzing the relationships between knowledge entropy and weight. The new method with a practical example can be proved to be good applicability and efficiency without any prior knowledge.
