Abstract
The aim of our study is to develop a creativity support system which uses analogical reasoning. We adopt patent documents for extracting base knowledge in analogical reasoning on the system because patent documents have the following features; 1) Patent documents have potential to be extracted a sort of causal relationship between a method of invention and its effect, since the relationship is described in patent documents; 2) Extracted causal relationships have potential to be applied to industry, since patent documents include various industrial fields. Therefore we tried to extract some causal relationships from patent documents in fiber engineering, and some causal relationships between compound and its property are obtained. After that we extracted some causal relationships from patent documents in pharmaceutical field, and contrived a method for analogical reasoning by using the obtained causal relationships and similarity of keywords. Those results of our study are described in this paper.
