Abstract
An inference processor includes a production rule memory, a meta knowledge generator, a meta knowledge memory, a production system interpreter, and a working memory. The meta knowledge generator obtains production rules satisfying transition conditions between all the combinations of the states of the respective variables in the production rules as a directed-graph matrix. The meta knowledge generator then decomposes the directed-graph matrix into strongly connected components, and obtains, as meta knowledge, 1) variable-conditions of the respective strongly-connected components and 2) production rules satisfying transition conditions between the respective strongly-connected components. The interpreter generally determines an inference path from a given state to another state as a target on the basis of the meta knowledge, and efficiently executes production rules, thereby performing inference processing.
