In order to avoid project managers’ failing to perform appropriate risk control actions in a planning phase of the project, we propose an awarene ss system to display the appropriate risk control actions to the project managers. Because the project manager needs practical risk control actions, the awareness system extracts sentences of risk control actions from past project report s that are accumula ted in the information system development company. The proposed system identifies the sentences that are related to the target risk in the project reports and extracts sentences of the risk control action from the project reports with the related sentences . In order to identify the related sentences to the target risk, the proposed system makes clusters of sentences with constraints to include sentences of risk control actions, and relates the target risk to the cluster that has the similar sentence to the sentence of the target risk. The experimental result shows that the proposed system can extract the sentences of risk contro l actions at F- measure of 65.7%.
