PP Scholar - A P2P Network for Scholarly Literature Searching

Google Scholar provides a simple way to search for scholarly literature by crawling the information from publishers´ websites into Google´s database. However Google Scholar has its drawbacks. In this paper, we discuss about these drawbacks and present our project PP Scholar, which is built on Gnutella network and Dublin Core metadata standard. Our goal is to make the publishers´ databases cooperate in a P2P manner and build up a metadata-based P2P searching facility for scholarly literature. We take advantage of two kinds of power-law distribution found in Gnutella network, and make some adaptions by adding learning peers to improve our application in several ways.
