Abstract
There exists vast amount of web pages created in the past and left unchanged on the Web. It is expected those pages could be utilized as a resource to know the past. This paper focuses on trend information in the past, and defines context search as a search conducted for knowing the past trend. The context search method proposed in this paper treats retrieval volume by Google Insights for search and search engine's hit count as Web context information. Effectiveness of the proposed method is shown with experimental result, in which objects are game titles.
