Abstract

In our previous work, we proposed the ontology-based integration of data warehousing to make existing data warehouse system more user-friendly, adaptive and automatic. This paper further outlines a high-level picture of the ontological engineering in data warehousing. Its basic theory includes building ontology profiles for warehousing in terms of domain ontology and problem-solving ontology, analyzing ontological commitment and semantic relationships of ontological items, aggregating, transforming, mapping, querying and discovering semantic relationships and/or ontological items crossing multiple relevant ontological domains. We introduce and illustrate them very briefly in terms of a web-based electronic institution F-Trade.
