Abstract

The authors describe a coupled system for knowledge-based signal understanding. This system maintains two separate, collaborating knowledge bases, one for the signal analysis knowledge and one for the domain specific knowledge. An object-oriented approach is followed to ease the knowledge representation for both fields of expertise. A vocabulary (or language) is provided to facilitate interaction between the two experts and the two knowledge bases. This same language contains elements to express spatial and temporal relationships and to provide adaptation of object descriptors as the analysis progresses. Following the approach described here, the authors have developed two prototype application systems, for EEG analysis.<>
