Embedding the production system in C language

Production systems, such as ops5, have been widely used in menu knowledge-based systems and expert systems. With the development of large scale knowledge-based systems and more sophisticated expert systems, the processing ability of production systems has become a bottleneck. C is a general purpose language, it is used in many fields of software design. But C hasn't the components to represent knowledge and perform inference; it is not quite suitable for knowledge processing. We embed production systems in C, and design a new version of C (PSC). This makes use of the advantages of C and production systems. The design and implementation of PSC are discussed.<>
