Method for constructing process case layered knowledge model for knowledge push

Abstract

The invention discloses a method for constructing a process case layered knowledge model for knowledge push. The method comprises the following steps of: constructing a product case matching vector set after decomposing product cased, and taking the product case matching vector set as a case matching layer for dragging knowledge push content in a process case layered knowledge model; aiming at each product case and each design process, constructing a design content vector set, and taking the design content vector set as an original case layer for forming design process information; constructing a case knowledge vector set according to the design content vector set and a knowledge document, and taking the case knowledge vector set as a complete knowledge layer for associating design objects with processes; and refining the case knowledge vector set of the complete knowledge layer to form a refined knowledge document set vector set, and taking the refined knowledge document set vector set as a specific knowledge graph formalized refined knowledge layer. According to the method, the constructed knowledge model is clear in structure, simple and convenient to construct and management, and suitable for knowledge push links.

Description

technical field [0001] The present invention relates to a method for constructing a knowledge data model, and mainly relates to a method for constructing a process case layered knowledge model for knowledge push, aiming at constructing a knowledge base in the early stage of design knowledge push for complex mechanical equipment. Background technique [0002] With the rapid development of computer and artificial intelligence technology, the design process of mechanical products in the information age has also changed. Among them, the traditional mechanical design process requires manual query of corresponding knowledge, resulting in low design efficiency, long design cycle, and poor design results. Knowledge push in the design process has become a research hotspot in intelligent design. A simple summary of knowledge push technology is that during the design process of mechanical products, the right knowledge is pushed to the right person in the right form at the right time to...

However, in the preparatory stage of knowledge push, there are few studies on the construction method of knowledge base

In the general knowledge push, the ontology-based knowledge base construction method is used to pave the way for the subsequent knowledge semantic matching. The disadvantage is that the knowledge content and related semantics are complicated, which makes the knowledge construction result complicated and lacks effective management.

In addition, the general case knowledge construction is a flat knowledge accumulation model, and the single knowledge structure is not conducive to the audience experience of knowledge push

In addition, there are some studies on knowledge base construction methods in other fields, but there are few knowledge base models that specifically study the knowledge push link in mechanical design.
