Issues of Integration and Balancing in Hybrid Knowledge Representation Systemsge representation formalism cannot meet all representational demands. In this paper we will present one particular hybrid knowledge representation system, BACK, concentrating on matters of how to integrate different subformalisms and their interpretation. In particular, `balancing the expressiveness

Higher-order Concepts in a Tractable Knowledge Representationsentation formalisms is usually avoided. In fact, this needn’t be so. We present the knowledge representation of the knowledge acquisition system BLIP, and describe how higher-order concepts are represented by using . We then show that metapredicates have the necessary properties to qualify for incl

The CATWEAZLE rule interpreter allows the knowledge engineer to partition rule bases and specify meta-level architectures for control..Among others the following questions arise immediately when one wants to provide tools for specifying meta-level architectures for cont

Modelling Heuristic Parsing StrategiesBesides a correct grammar, the strategy that applies the grammar rules to the input plays an important role in the performance of natural language parsers. In this paper a framework is presented offering comprehenensive facilities for defining and testing parsing strategies based on various heuristic criteria.
