Discovering new topics which cover new items, problems, and ideas (e.g., mobile phone, global warming, human genome project, etc) is truly profitable, important, and interesting for us. For instance, 1. Companies producing ’mobile phones’ have made large profits by the great sales, 2. The awareness of ’global warming’ has improved the environment of the earth by regulating exhaust emissions, 3. Fatal illnesses might be conquered by the human genome project. However, since we cannot completely decode the world surrounding us, we cannot know the topics and their mechanisms in advance. Considering this situation, these phenomena could be a big chance for our activities. In this paper, we describe our approach for discovering the future directions of communities on the web to detect chances.
