CAT-CBR

Component Architecture Technology for developing CBR systems

CAT-CBR is a component-based platform for developing CBR systems. CAT-CBR uses UPML (Unified Problem-solving Methods Language) for specifying CBR components. A collection of CBR components for retrieval of propositional cases is presented in detail. The CAT-CBR platform guides the engineer using a case-based recommendations system to develop a configuration of components that satisfies the requirements of a CBR system application.

CAT-CBR provides:

A library of CBR components (currently for retrieval and for classification; reuse components are being developed).
A language and a graphical editor to specify new components and a syntax to implement their operational code.
A broker service allowing
1. to specify the requirements of a target CBR application and the available models in a domain, and
2. to search for a configuration of components that satisfy the requirements
There is an automatic broker service and an interactive broker service where the user selects the components supported by the case-based suggestions provided by the broker.
CAT-CBR generates the "glue code" that binds together the operational code of the configured components into a stand alone application.

CAT-CBR has been implemented on the NOOS Platform.
