Organizing personal web 2.0 content with Hypersea

Hypersea is a system based on spatial hypertext, node linking and other hypertext research features and its aim is to facilitate users to visually organize content originated from web2.0 and other multimedia sources. Hypersea can be used for any kind of on-line or off-line content in desktop and mobile devices. Its design is focused on information pieces coming from online web2.0 applications, which are stored as structured nodes with visual and spatial characteristics that can be explicitly or implicitly linked. This paper discusses Hypersea philosophy and principles, and illustrates examples for organizing web2.0 content. Vice versa, we propose how existing web2.0 applications may benefit from Hypersea visualization characteristics. For example, blog entries and Facebook profiles, which are displayed as long text-based pages, can be reorganized in order to enable the user to focus and navigate towards the desired information. We also show how Hypersea has been implemented by using the ontology paradigm. With this implementation, we show how ontologies can be combined seamlessly with visual, spatial interfaces. Finally, we provide some premilinary evaluation results and future work.
