We propose a method to enhance web browsing history records by considering browsing window attributes. The browsing window attributes means properties of web browser window such as size, location, z-order, activated status, etc. We often open multiple web documents for each window and browse the contents through handling these windows at the same time. Since a series of the window attributes describe the user’s browsing activities, we exploit the attributes to enrich the browsing records to help the user find previously visited web pages.
