An integration system of Web information sources for mobile users

Today, there are many Web information sources (WISs) that are suitable for mobile users. How/when to integrate such Web contents (which may be location-dependent contents) into a new simpler WIS for mobile users will become a problem, because different mobile users need different integration. A possible solution is to allow each individual mobile user to directly define, on his PDA, which pair of WISs should be integrated in what ways. Thereafter, system-side servers should materialize a definition (issued from a user's browser) as a new WIS. For this purpose, the paper introduces a new style of integration called navigational integration of WISs, and then describes a system architecture.
