Embodiment 1

[0066] The invention provides a method for maintaining construction machinery software, comprising the following steps:

[0067] Step (1) Construct a software hierarchical clustering model based on functional requirements;

[0068] Step (2) retrieves the corresponding software code based on the modification request and the software hierarchical clustering model;

[0069] Step (3) maintaining the hierarchical clustering model based on the retrieved software code.

[0070] In a specific implementation manner of the embodiment of the present invention, the construction method of the software hierarchical clustering model includes:

[0071] (101) Preprocess the functional requirements to obtain effective feature values; specifically: apply the basic rules of text preprocessing in information retrieval technology to convert the functional requirements expressed in natural language into verbs plus names or nouns plus verbs Standard text: Use the word segmentation tool to perform w...

Embodiment 2

[0130] Based on the same inventive concept as in Embodiment 1, the present invention provides a construction machinery software maintenance system, including:

[0131] The building block is used to construct a software hierarchical clustering model based on functional requirements;

Abstract

The invention discloses an engineering machinery software maintenance method and system, and the method comprises the steps: building a software hierarchical clustering model based on a function demand; retrieving a corresponding software code entity based on a modification request and the software hierarchical clustering model; and maintaining the hierarchical clustering model based on the retrieved software code entity. According to the method, the process that maintenance personnel understand software, analyze programs and then execute modification work can be simplified, a large amount of labor cost and time are saved, and a convenient and effective method and direction are provided for software maintenance.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a method and system for maintaining software of engineering machinery, and more particularly relates to a method and system for retrieving engineering machinery software codes based on a hierarchical clustering algorithm. Background technique [0002] In recent years, construction machinery has developed rapidly, and the development of mechanical digitization and automation has become a new development trend. The functions of construction machinery are increasing day by day, and the software system is constantly evolving. After the software is delivered and operated, users often put forward new modification requests due to the addition of new requirements, discovery of new software faults, and adaptation to the new environment. proportion is also increasing. The modification request put forward by the user is usually described in natural language. When ...
