    Search engines help people to find information in the largest public knowledge system of the world: the Web. Unfortunately its size makes very complex to discover the right information. The users are faced lots of useless results forcing them to select one by one the most suitable. The new generation of search engines evolve from keyword-based indexing and classification to more sophisticated techniques considering the meaning, the context and the usage of information. We argue about the three key aspects: collaboration, geo-referencing and semantics. Collaboration distributes storage, processing and trust on a world-wide network of nodes running on users’ computers, getting rid of bottlenecks and central points of failures. The geo-referencing of catalogued resources allows contextualisation based on user position. Semantic analysis lets to increase the results relevance. In this paper, we expose the studies, the concepts and the solutions of a research project to introduce these three key features in a novel search engine architecture.

    Interactive Web-based Applications Enforcing Communication and Cooperation in Distributed Teams
    (Polimetrica, 2005-07) Soro, Alessandro; Angioni, Manuela; Carboni, Davide
    In this paper we show the work ongoing at CRS4, on the topic of collaboration tools. We describe DJ-Lab, a plugin for the popular integrated development environment IntelliJ Idea that supports the practice of remote pair programming; XP4IDE, that automates the activity of tracking of XP managed development projects and integrates in the IDE a view of the project tasks; and WebRogue, an application for virtual presence in Web sites, that allows web users to see the other people connected to a web server and communicate and cooperate in various ways. The philosophies of these applications are analyzed to spot analogies and differences, potential evolutions, technical and human limitations, and track a path for future development.
