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.
