Applications based on the Web 2.0 approach show several limitations: among them, knowledge is usually manually generated by users and can not be structured and shared in effective ways.
This paper presents an innovative architecture, conceived in terms of a multi-agent systems and
aimed at creating, managing and sharing personal information spaces.
Data and knowledge may be directly added by users, but also collected and structured with the support of content retrieval, filtering and automatic tagging techniques.
Conceptual spaces organize personal information spaces using zz-structures, an innovative system of conventions for data and computing, capable of representing, by means graph-centric views, contextual interconnections among heterogeneous information.
