Information and Knowledge Reengineering for Reasoning from Cases (1996-1999)

The ESPRIT project Inreca II was the successor of the project Inreca (Induction and Reasoning from Cases). The major concern of Inreca II was to offer an experience-based (development of a) methodology and a set of tools that supports the methodology for guiding CBR application development, validation, and maintenance. The Inreca II methodology is composed of a set of steps, guidelines and recommendations that allow a primarily non-CBR user to build, to validate, to maintain, and to scale up a CBR application. These steps include the initial understanding of the CBR technique, the building and the maintenance of a CBR application, and the evaluation, qualification and acceptance process of the CBR system being built. Inreca II showed the applicability of this CBR methodology to a variety of application tasks. These applications leverage the project in the sense that they will enable to apply an initial methodology, to make it grow and finally validate it. The project also resulted in a set of tools for building integrated case-based reasoning applications. The tools represent a significant commercial opportunity for the industrial partners of the project. Furthermore, Inreca II enhanced current CBR technology in the areas of solution adaptation.
