1. Technical Field
The invention relates to Web browsing. More particularly, the invention relates to a method and apparatus for establishing and maintaining a categorized Web browsing history.
2. Description of the Prior Art
Browser history is generally shown as one or more flat lists that are column sortable by date last visited, visit count, URL, or page title, etc. It is difficult to find specific items in such lists. It is also difficult to find groups of similar sites that were once found and visited. In frustration, most people often resort to starting from scratch and use a search engine to re-find a site in the same way they found it in first place. Browser history is simply unfriendly.
It would be advantageous to provide a simple, user-friendly method and apparatus for establishing and maintaining a categorized Web browsing history.
The invention provides a simple, user-friendly method and apparatus for establishing and maintaining a categorized Web browsing history. A presently preferred embodiment of the invention uses a directory service, such as the Open Directory Project, to get category metadata about visited URLs. Metadata thus obtained are used to present a user's personal browser history in a category based hierarchy.
A presently preferred embodiment of the invention provides a simple, user-friendly method and apparatus for establishing and maintaining a categorized Web browsing history. A presently preferred embodiment of the invention uses a directory service, such as the Open Directory Project, to get category metadata about visited URLs. Metadata thus obtained are used to present a user's personal browser history in a category based hierarchy.
A particular feature of the invention leverages the existing publicly accessible databases of URL categorization and uses that information to build a presentation in the browser that users can navigate and explore. For example, the Open Directory Project (ODP; see http://dmoz.org/) is a widely distributed database of Web content classified by humans. ODP maintains a database, and exposes a Web interface, that allows navigating through categories to find Web sites (see
These categories are structured as trees, where each node has zero or one parents and zero or many children.
As shown in
This data model permits one to build interactive user interfaces that allow users to navigate among the categories corresponding to URLs that have been previously visited while browsing. Unlike the ODP user interface, it does not include categories that correspond to pages the user has never visited.
The user interface for this hierarchy of data can be displayed as a tree list, as with the Windows file system Explorer, or as a series of Web-style pages, as with the OPD Website. The resultant user interface allows users to re-find Web sites by drilling down through familiar categories. It also allows users to discover groups of previously visited pages which happen to fall into the same category. This grouping can be very useful to users. Optionally, from any given category display the user interface can supply a link back to the full ODP Web page for that category. Thus, within the same user interface, the user can focus on previously visited pages and then navigate to a wider view of similar pages that might be worth exploring.
Although the invention is described herein with reference to the preferred embodiment, one skilled in the art will readily appreciate that other applications may be substituted for those set forth herein without departing from the spirit and scope of the present invention. Accordingly, the invention should only be limited by the claims included below.
