CREEK and Description Logics
MetadataShow full item record
Creek is a system for diagnosis and problem solving. It makes heavily use of general knowledge, and is intended for open and weak theory domains. The system uses this general knowledge in combination with experiences from previous cases to solve new problems.We have implemented the core parts of Creek inside the Colibri studio framework, and shown that it is both possible and realistic to create a thorough Creek implementation. This has resulted in a system named Colibreek.In this implementation, we have replaced the knowledge representation in Creek, switching from the original frames to description logics. This has proven successful, and promising for further development.We have tested our system on the turbine sensor domain, and shown how our system can be used for condition monitoring on sensor-monitored equipment such as turbines. By doing this, we have also shown how the system can solve real problems people, companies and organisations have.
