A Semantic Approach in Modeling and Visualizing WWW Bookmarks

Abstract:- Bookmarks are the facilities found in current web browsers, which allow a user to revisit a WWW page. Most WWW browsers provide a hierarchical structure for aiding bookmark organization in searchable subsets. Average users tend to create a large number of bookmarks during multiple browsing sessions and con-sequently such hierarchies quickly become complex and hard to manage. Moreover, it is questionable whether a user recalls the significance of a single bookmark in the context of his current informational needs, as the ma-jority of WWW browsers only store the title of the relevant page. As an answer to the aforementioned issues, we propose a novel system, which supports the organization of bookmarks and also suggests a 3D spatial meta-phor as a visualization technique for navigating within bookmark collections. In specific, a semantic modeling framework for shaping the bookmark “space ” and a corresponding 3D visualization for this “space ” are sug-gested. The proposed framework is able to capture both human and system derived meta-information which describes bookmarks. It also incorporates inference capabilities by exploiting fuzzy set theory and fuzzy logic. Additionally, this paper attempts to define the types of meta-information, which could be utilized for describing bookmarks. Finally, a system architecture for acquiring, manipulating and visually rendering these types of meta-information in a 3D spatial context is proposed
