A Community Web portal is a set of tools for a community of people who want to share information on a certain do- main via the Web. The backbone of this system is an onto- logy which is understood by all members of the community and used as the common interface component for integrat- ing, querying, structuring and exchanging information. This paper describes a simple but nevertheless powerful language for integrating XML documents into a Community Web sys- tem. More precisely, we describe how to add and exploit XPath enabled Web servers by mapping standard XPath loc- ation paths to conceptual paths in the system ontology. We present a query rewriting algorithm using such mappings. It transforms a user query into a set of XML queries based on XPath patterns for selecting XML fragments. Finally, we de- scribe some evaluation techniques for reducing the size of XML data returned by the XML source for query evaluation. |
