摘要: The Hearsay II speech-understanding system (HSII) (Lesser et al [11], Fennell [9], and Erman Lesser [6]) is an implementation of a knowledge-based multiprocessing artificial intelligence (AI) problem-solving organization. HSII intended to represent organization which applicable for in parallel hardware environment such as C.mmp (Bell [2]). primary characteristics this include: 1) multiple, diverse, independent asynchronously executing knowledge sources (KS's), 2) cooperating (in terms control) via generalized form the hypothesize-and-test paradigm involving data-directed invocation KS processes, 3) communicating data) shared blackboard-like data base current state held homogeneous, multidimensional, directed-graph structure. object paper explore several ramifications by examining mechanisms policies underlying are necessary supporting its system. In addition, multiprocessor simulation study presented details effects actually implementing use particular application area, that speech understanding.
