An Ontology-based System for Semantic Filtering of XML Data

In this paper, we describe a system, written in Haskell, for the ontology-based approximate filtering of XML data. Basically, it allows one to extract relevant data as well as to exclude useless and misleading contents from an XML document. The system provides a declarative language one can use to define XML patterns and ontology queries to express syntactic as well as semantic filtering criteria. The system can be used through a Web application which is endowed with a user-friendly graphical interface. Finally, we provide some meaningful examples which show the usefulness of the implemented filtering methodology.
