This paper addresses a problem to identify risks in project plan documents written by project managers. Because some project managers express risks without negative words, risk identification method by negative expressions is not enough to identify them. In this paper, we propose a risk identification method by automatic acquisition of risk expressions. The proposed method acquires the risk expressions from existing project plan documents by using the frequency of appearance in the sentences including the risks. After the acquisition of the risk expressions, the proposed method extracts the sentence where the expression indicates the risk. From the extracted sentence, the proposed method identifies the risk by comparing the items of the checklist of risks. In particular, the proposed method identifies the items corresponding to each extracted sentence by using related words of each item. The experimental result shows that the proposed method identifies 10.7 known risks and 5.8 unknown risks on average.
