The World Wide Web is remarkably developing as a simple and inexpensive means for sending information, and various people have been expressing their opinions from different standpoints on the Web. Consequently, the Web is rapidly becoming a treasure house of public opinion about any and all topics. In recent years, studies of extracting other people’s opinions from the Web have been started [3–5]. They have proposed a system that collects other people’s opinions about a user-specified event or thing from the Web, evaluates the opinions on several evaluation axes, and shows the results using a radar chart. However, their system cannot show a general view of the overall opinion because the system averages the opinions and forms a conclusion. We, therefore, propose a novel Web-based question answering system named Web OpinionPoll that collects other people’s opinions about a user-given concern from the Web, and presents a general view of the opinions in a visual way. This system helps users intuitively understand answers to questions that request others’ opinions.
