Abstract:
Nowadays, XML plays an important role as a de
facto standard online data exchange mechanism. In
this paper, we present NFA-based filtering technique
of XML document for multiple XPath queries using
ontology. In our proposed system, the XPath queries
are transformed into Nondeterministic Finite
Automaton (NFA) - based model. The proposed
system separates NFA into the structural NFA and
value-based predicate NFA. In order to get the
semantic adequacy of XPath queries into NFA form
are transformed with the help of ontology which is to
append into structural NFA. Incoming XML
document is parsed by SAX parser. Then, matching
XML document and NFA based user profiles.
Therefore, the proposed method intends to provide
not only exact matched information but also
semantic matched information from XML documents.
