Most existing web search tools do not utilize previous search experiences of others to improve performance for the current user. In this article, we present a collaborative web agent designed to enable across-user collaboration in web search and recommendation. We use our distributed collaborative filtering (CF) algorithm based on a P2P overlay network of autonomous agents. Experiments show that our proposed scheme is more scalable than traditional centralized CF filtering systems and alleviates the sparsity problem in distributed CF.
