Abstract : Textual information retrieval is one of the main tasks related to the Web. This task relies generally on search engines, which have become an essential tool of the Web. Indeed users start at a search engine 88% of the time when they have a new task to complete on the Web. However, confronted with the huge increase of available information on the Web and the lack of significant evolution of the search process, the amount of documents matching a query becomes awfully important. It's therefore difficult for the user to effectively interpret all these results. This problem of representing search result is addressed though information user interfaces (IUI). Much work has been carried out on search result visualization since a decade, without real impact on the most popular user interfaces. Our approach focuses on the necessity to dynamically create interactive 3D presentations based on visualization metaphors adapted not only to the end-user, but also to the task to complete as well as to the data. We have thus developed the SmartWeb prototype that proposes hybrid interfaces (2D/3D) for the visualization of search results. It uses the X-VRML language that enables to effectively design 3D visualization metaphors and automatically generate interactive 3D content. We propose a cognitive 3D metaphor allowing for a richer space representation, which efficiently and effectively helps users in their tasks. A user study of this interface was carried out and an evaluation framework for IUI is proposed.
