XML-based Data Integration for Semantic Information Portals
نویسندگان
چکیده
This paper addresses some classical problems to integrate data sources that are heterogeneous in structure with possibly redundant data along a real world example integrating three bibliographic data sources. We show how XML-technology can be applied for the data integration process in a straight-forward manner to populate a data warehouse, how an ontology can be used as common schema, and how a generic, declarative approach can increase flexibility and scalability. Our procedure enables more advanced query functionality for integrated data sources.

Integration of Spatial XML Documents with RDF
The fact that GML is an XML encoding allows it to be queried. In order to query a GML document we have designed a query language over GML/XML enriched with spatial operators. This query language has an underlying data model and algebra that supplies the semantics of the query language. In this paper, we propose an approach for integrating Geospatial data on the Web, stored in GML documents, usi...

We propose an architecture for a new kind of federated search system, which takes these aspects and new developments into account. A major challenge in this context is to cope with portals and the data sources behind t...

متن کاملUsing Semantic Web Services to Integrate Data and Processes from Different Web Portals
Integration and exchange of information across the Internet is a universally recognized need, in a wide variety of domains. New promising application fields such as Semantic Web Services can improve the integration process in the Web, dealing with the major difficulty of the semantic heterogeneity in the resources, by means of domain ontologies. In this research, we propose an integration syste...
