Embodiment Construction

[0019] This implementation mode is a method for extracting and expressing design decision-making knowledge, and establishes a model composed of three levels: design intent, design scheme, and design basis, as shown in figure 1 shown. The specific method is divided into three steps:

[0020] 1. Steps for generating the design intent layer:

[0021] 1) Input the design document W;

[0022] 2) Check whether there is a standard title format in the design document W, if there is no standard title format, go to step 3), if there is, go to step 4)

[0023] 3) Change the design document W using Apache POI to standardize its title;

[0024] 4) Use the Apache POI method to obtain all titles in the document and the inclusion relationship between them;

[0025] 5) Store all the acquired titles into the design intent candidate set P according to their levels;

[0026] 6) Construct a word set D, the words in D are words that cannot be used as the design intention after a large number o...

Abstract

The invention relates to an extraction and expression method of design decision-making knowledge. Specific to the demands of acquisition of the design decision-making knowledge and completion of modelbuilding, the discovery and extraction of the design decision-making knowledge in a design document are realized from the three aspects of design intention, design plan and design basis through a template operation of the design document. Extracted design decision-making knowledge is reconstructed by a design decision-making knowledge hierarchical model, so that the extraction and expression of the design decision-making knowledge in a historical design document can be realized; a design decision-making knowledge base is formed; and the design efficiency and design quality are improved.

Description

technical field [0001] The invention belongs to the research content of knowledge resource management and application method in the field of computer application technology, more specifically, the invention relates to a method for extracting and expressing design decision knowledge. Background technique [0002] Design decision-making knowledge reflects the dynamic psychological behavior process of designers using various professional knowledge and experience to define design problems, generate design concepts, and make design decisions. Generally speaking, design decision-making knowledge is an explanation of why a product is designed in this way. Effective acquisition, organization and application of design decision-making knowledge play a decisive role in improving design quality and design efficiency. Design decision-making knowledge is usually divided into explicit decision-making knowledge and implicit decision-making knowledge according to the existing form. Explicit...
