Mobile Clustering Engine

Although mobile information retrieval is seen as the next frontier of the search market, the rendering of results on mobile devices is still unsatisfactory. We present Credino, a clustering engine for PDAs based on the theory of concept lattices that can help overcome some specific challenges posed by small-screen, narrow-band devices. Credino is probably the first clustering engine for mobile devices freely available for testing on the Web. An experimental evaluation, besides confirming that finding information is more difficult on a PDA than on a desktop computer, suggests that mobile clustering engine is more effective than mobile search engine.
