Special Issue on Semantic Web and Data Warehousing
 
The deployment of data warehouses (DWs) to integrate disparate data sources within a separate database for analysis purposes has become a standard technique in modern IT landscapes. Nevertheless in practice the development and application of DWs still pose a number of challenges which are mainly concerned with the documentation, exchange, and integration of metadata. On the other hand, the Semantic Web nowadays offers languages for the automatic reasoning of metadata semantics which should be of great use in the context of DWs, but have not been explored in this direction yet. 
 
In the DW context we have to specify analysis requirements of end users, identify necessary data items and their computation formulas, that have to be matched with available source data, and documented. In addition extraction/transformation/load (ETL) processes have to be set up to integrate source data into the DW. Ideally, the metadata involved should be represented in conceptual terms, the semantics should be described by ontologies, and thus the contents of ontology-driven DWs should be accessible for automated semantic processing, querying, and transformation. However, in practice documentation turns out to be missing, incomplete, and inconsistent, while a large fraction of solutions is hard-coded within proprietary formats of commercial tools, hindering exchange, integration, optimization, re-use, and evolution. The application of Semantic Web technology in this context can add a platform-independent conceptual description of DW contents and multidimensional structures using ontology languages (e.g., Web Ontology Language (OWL)) that include powerful formal semantics to enable automated reasoning. 
 
For this special issue on the Semantic Web and Data Warehousing, we welcome papers reporting original research relevant to topics at the confluence of data warehousing and the Semantic Web, such as
 
- ontology-based design of dimension hierarchies, measure schemata, and ETL processes,
- ontology-enabled data analysis using semantic query reformulation techniques, 
- ontology-driven guided user interfaces providing helpful explanation components,
- ontology-based techniques for automated source integration, schema matching, and schema versioning,
- industrial use cases and applications.
