Abstract
Modern knowledge-based systems require fle … Modern knowledge-based systems require flexible means of maintaining continuous and spontaneous communication with multiple external entities. Some of them are real-time systems, which must respond to an input within a specified interval of time.Two common approaches to communication in blackboard systems, communication knowledge sources and a communication phase in the reasoning cycle, can not generally satisfy real-time constraints. A design based on a concurrent communication process can satisfy real-time constraints. An application communicates with external entities solely through device-independent logical streams in its knowledge base. The communication process is continuallly transferring data between external physical streams and the logical streams.We describe an architecture-independent Communication Interface (CI), and describe its use with the BB1 blackboard architecture. In a suboptimal test configuration, the CI currently can effectively transmit data to the knowledge base at rates up to 8 items per second. The transmission rate can be increased in proportion to increases in processor speed, network speed, and by program optimization, independent of changes in the reasoning architecture. of changes in the reasoning architecture.
