In the ubiquitous environment, it becomes important to support people who move in the real world to get information from the Web. In this paper, we consider the situation that the user walking around the real world makes a decision whether or not he/she uses a geographical facility. We develop a system which displays Blog documents about the geographical facility the user got interested in through the mobile terminal. The system searches Blogs on the Web by using not only the facilitys name but the keyword about the users objective. The user just selects the users objective from the candidates created from common sense database. The system extracts the surrounding text of the selected objective from the Blog documents for decreasing the quantity of the information for the user. The evaluation showed that the system can improve the users confidence of the decision and decrease the users effort when he/she has to make a decision in short time.
