We have proposed a method that acquired concept relation rules from some texts with text classes. The method deals with only a training example that all concept class has at most a key concept. The paper proposes a method dealing with a training example that some concept classes have multiple key concepts. The method incorporates the membership function, which processes single key concept as a special case of multiple key concepts in each attribute, into a fuzzy inductive learning method. Also, the paper compares the revised fuzzy inductive learning method with an old fuzzy one and C4.5.
