To evaluation enterprise, it is important to consider not only enterprise financial states but also enterprise strategies or those changes. In this article, we extract the strategy words of the enterprise from the investor relations information published by the enterprise (IR information).
In the enterprise strategy words appearing in IR information, there are many originally created words by companies, such as coined and proper words and so on.
It is difficult to extract these words by morphological analysis with dictionary. So, we propose a method which consists of the following steps. (1) To extract candidates of strategy words by N-gram analysis. (2) To reduce noise words by using corpus of the common words that appears frequently in Japanese documents except IRs.
