Information and knowledge re-engineering for reasoning from cases

Objective

The central aim of INRECA II is to develop a methodology and a set of tools for building systems that reason from past experience.

Case-based reasoning (CBR) is a technology that solves problems by storing, retrieving, and adapting past cases. The main focus of INRECA II is to develop and apply a methodology to cover the whole life cycle of CBR applications and preserve corporate knowledge. Building a CBR system is more of an art than of a replicable industrial activity and some additional research and development needs to be done in order to provide adequate technological and methodological support for engineering and re-engineering the knowledge required to initially build and maintain a CBR application. This includes knowledge identification, modelling, and maintenance, where knowledge can come from various sources. The project includes the application of the methodology and techniques at Mercedes Benz and at least in two other domains.

The project will rely on the results of Esprit INRECA (P6322) and APPLICUS (P20824) and on the partners experience in software and knowledge engineering and re-engineering. INRECA II will:

- Produce a core methodology for building and maintaining CBR diagnostic applications. This will be based on work carried out in the past during INRECA and APPLICUS and on the requirements analysis of the selected pilot application (sales support of utility vehicles).
- Evaluate, refine and validate this methodology through the pilot application, and derive an architectural vertical platform (i.e. methodology and tools) that addresses the general market of sales support. Additionally, at least two other applications will be built during the course of the project. These applications will act as 'proofs of concept' and will aim at validating the genericity of both the methodology and the tools developed.
- Provide adequate tools and methodological support for all the important phases in the CBR application development life cycle by reusing multiple knowledge sources. This includes the initial development, but also the testing and maintenance when the focus of the decision making process evolves.

In order to determine and to implement methodological guidelines that aim at managing the whole life cycle of an application, INRECA II will integrate current CBR technology with other up-to-date information technologies (databases, information retrieval, documentation management tools, networking). Techniques known in knowledge acquisition from structured and unstructured data will be integrated and adapted to the specific use of CBR. INRECA II will widen the scope of CBR technology from analytic to synthetic problem tasks with a special focus on such applications that can be efficiently handled with current software technology.

The project will also further contribute to European standards by extending Casuel, the case and knowledge representation language developed in INRECA.
