Document Analysis Based on Text Mining (TRIZ)
Documents contain important technical knowledge and research results. They have high quality information to inspire designers in product development. However, they are lengthy and have much noisy results such that it takes a lot of human efforts for analysis. And due to the fact that hidden and unanticipated information plays a dominant role for TRIZ "Theory of Inventive Problem Solving (TRIZ)".The main purpose of using TRIZ is not learning new technologies but obtaining or generating new ideas for solving the authors' own technical problems. Examples in other fields, especially basic and typical examples, are valuable for this purpose.
