ABSTRACT
In recent years, publish subscribe systems based on XML document filtering has been on tremendous rise. Many filtering mechanisms exist such as XFilter, YFilter, AFilter etc. But most of these mechanisms do not filter the document for semantic matched information. M-Filter performs semantic matching of XML documents. But value-based predicates cannot be filtered by M-Filter. This paper proposes a new technique which does semantic matching of XML data and also handles value-based predicates. User Profiles are specified as XPath queries. A query node is checked in OWL classes, if a node is found it is returned with its semantically related data. These queries are then converted into twig patterns. On the other hand, XML document is parsed by DOM parser and a tree is built. Matching of twig nodes and the tree nodes takes place and only the matched information is displayed to the user.
