Mechanical product design two-dimensional knowledge pushing method based on design intent

Abstract

The present invention discloses a mechanical product design two-dimensional knowledge pushing method based on design intents. The mechanical product design two-dimensional knowledge pushing method mainly comprises: establishing a mechanical product design intent database, establishing a design intent acquisition and decomposition method, constructing a design intent attribute table by a rough set theory and performing reduction to obtain the simplest design intent set; establishing a mechanical product design knowledge ontology database; and calculating similarity degrees between intent elements and a compared knowledge ontology in a sequential traversing manner by using an improved similarity degree matching algorithm based on a knowledge ontology concept semantic distance and a concept attribute, sequentially carrying out matching on each intent element, of which the similarity degree is greater than a threshold value, in an intent element set from large to small according to the similarity degrees until completing all the matching, and completing matching of the knowledge ontologies by utilizing a text semantic similarity degree calculating method. The mechanical product design two-dimensional knowledge pushing method can solve the problem of low knowledge intelligent degree of knowledge pushing in the mechanical product design, can improve efficiency of mechanical product design and is suitable for the requirement of the manufacturing information engineering technology for deepening development.
