Value-Based Predicate XML Filtering System

Abstract

Nowadays, information dissemination applications are very popular and much of the data exchange over the Internet. Existing XML filtering techniques based on a publish/subscribe model on highly structured data marked up with XML tags. These techniques are efficient in filtering the documents of data centric XML but are not effective in filtering value-based predicates of document centric XML. In this paper, we propose a technique which does semantic matching of XML data and also handles valuebased predicates. User Profiles are specified as XPath Twig queries. A query node is checked in OWL classes, if a node is found it is returned with its semantically related data. On the other hand, incoming XML document is parsed by SAX parser and a tree is built. After then matching XML document and user profiles. Therefore, the proposed method intends to provide not only exact match information but also semantic matched information from XML documents.
