Abstract

This paper presents an approach to realize a case retrieval engine on top of a relational database. In a nutshell the core idea is to approximate a similarity-basedre trieval with SQL-queries. The approach avoids duplicating the case data or compiling index structures and is therefore ideal for huge case bases which are often subject to changes. The presented approach is fully implementeda s part of the commercial CBR toolbox orenge andt he experimental evaluation demonstrates impressive retrieval behaviour.
