Classification method for construction engineering change instructions

Abstract

The invention discloses a building engineering change instruction classification method. The method comprises the following steps: conducting document conversion processing according to the characteristics of constructional engineering documents, extracting the text content of each document, marking the category of each document, and establishing a constructional engineering corpus; constructing a building field dictionary, and performing word segmentation preprocessing on texts in the building engineering corpus by combining a word segmentation tool with the building field dictionary to obtain a text word sequence; establishing a word vector training corpus, and training a distributed word vector by adopting a word vector model; representing global word features and local syntactic features of the text based on a distributed method, and constructing text fusion semantic representation; constructing a classification model by adopting a supervised machine learning algorithm based on the text fusion semantic representation; predicting the to-be-classified documents, and rapidly obtaining instructions related to engineering changes in the to-be-classified documents. A natural language processing technology is utilized, the problem of low efficiency of manual classification of engineering documents in the building field is solved, and construction management of building engineering is facilitated.

Description

technical field [0001] The invention belongs to the fields of natural language processing and construction engineering, and in particular relates to a method for classifying construction engineering change instructions. Background technique [0002] my country's urbanization process has entered a high-speed stage, and the annual new construction volume of municipal facilities, houses, and traffic roads has increased significantly, and the scale of new construction projects continues to increase, and the architectural structure forms tend to be diverse. Construction projects are complex, involving multiple factors such as management, technology, and finance, and require the cooperation of multiple parties. As a communication document and construction basis between various units and departments, the work contact list records the plan confirmation, progress coordination, construction feedback, government documents and other information that occurred during the construction proc...
