Case-based reasoning and legacy data reuse for web based recommendation architectures

This paper describes a software framework for developing case-based reasoning (CBRL) components that are seamlessly integrated into an enterprise architecture. The framework exploits recent standardization initiatives in the area of XML databases and mediator systems. We show how a legacy database or an XML data source, which may be tagged using a standard vocabulary, can be easily reused as case base with minimal additional efforts. An application of the proposed framework to the development of a case-based recommendation system for tourism travel planning is illustrated
