Early Profile Pruning on XML-Aware Publish-Subscribe Systems

Publish-subscribe applications are an important class of content-based dissemination systems where the message transmission is defined by the message content, rather than its destination IP address. With the increasing use of XML as the standard format on many Internet-based applications, XML aware pub-sub applications become necessary. In such systems, the messages (generated by publishers) are encoded as XML documents, and the profiles (defined by subscribers) as XML query statements. Current solutions have limited or no flexibility to prune out queries in advance. This paper overcomes such limitation by proposing a novel early pruning approach called Bounding-based XML Filtering or BoXFilter.
