Abstract
In a recognition system using a knowledge base in which there is required tolerance for ambiguity and noises in a knowledge expressing system not having the cause-and-effect relation existing, for example, in a knowledge base system employed for pattern recognition. The knowledge base supported recognition system includes as an inference engine an apparatus in which a hypergraph is added to the data structure of the knowledge base to obtain a minimum cost tree or the like by use of costs assigned to hyperedges of the hypergraph. With this provision, there can be attained tolerance for ambiguity of the knowledge base and noises superimposed on input data.
