| Outline of Final Research Achievements |
Although a Web search engine is a necessary tool for us to access huge amount of information available on the Web, we think that there is a significant difference between function provided by existing search engines and users' information needs. Aiming at narrowing the gap, we focus on the task of answering trend-related queries. By focusing on the specific task, more advanced search functions can be provided compared with existing Web search engines. As the task of answering trend-related queries is supposed to be common in various domains, we expect it could be used for various purposes. Prototype context search engine provides three basic functions, which can be accessed via both of ordinary Web browsers and API. Experimental results using the prototype search engine show that users can break their information needs into several queries using those functions. It is also shown it can be used for finding relationship among different data resources.
