Element checking system for use in forward inference system.

摘要

An element checking system for use in forward inference system is disclosed. When checking elements, each element is read out as a token and transmitted through a checking network. The element checking system includes a memory for storing an element checking network. The network has a plurality of inputs for receiving the tokens one at a time, and a plurality of nodes for checking features of the received token. The system also includes working memory for storing elements, each element carrying data identifying a particular node from which the checking procedure in the networks starts. <IMAGE>
