With the popularity of Extensible Markup Language (XML) as the new standard of data exchange on the web, a large number of data sources are represented or encoded in XML format. Therefore, querying and searching XML data on the web has attracted much attention in the database literature. The new emerging Peer-to-Peer (P2P) computing model has fueled the autonomous data sharing over the Internet in a more flexible fashion. Needless to say, XML data retrieval in P2P systems has become attractive to professionals in both research and industrial communities. In this paper, we propose a Bloom-Filter based keyword search framework for XML data retrieval in structured P2P systems. We designed an efficient Bloom-Filter based XML indexing scheme for XML data retrieval in structured P2P systems. We also developed an effective keyword search algorithm over our Bloom-Filter encoded XML indexes. The experimental results demonstrate that our novel indexing scheme is much more efficient compared to the traditional full-indexing scheme, our keyword search algorithm is efficient in terms of query response time, and our system is scalable in terms of data size and network size.
