Newly increased requirement-based code variation quantitative evaluation method and system thereof

Abstract

The invention discloses a newly increased requirement-based code variation quantitative evaluation method and a system thereof and belongs to the technical field of computer software development. The method comprises the following steps of: (1) carrying out feature extraction on N requirements of a certain software item according to set requirement features; (2) selecting feature extraction data of m requirements in the item as training data and calculating an adjustment coefficient gamma of the software item; (3) carrying out feature extraction on newly increased requirements of the software item according to the set requirement features; (4) carrying out clustering on each newly increased requirement and the N requirements by using the feature extraction data in steps (1) and (3); and (5) estimating a code quantity E of the newly increased requirements according to a formula E=gamma.C. The system comprises a feature extraction module, a kernel clustering algorithm calculation module, an adjustment parameter gamma training module and a code quantity prediction module. Compared with the prior art, the system of the invention can automatically predict the code quantity to be generated by the newly increased requirements and can visually display an estimation result.

Description

technical field [0001] The invention relates to a method and system for quantitatively evaluating code change amount based on newly added requirements, and belongs to the technical field of computer software development. Background technique [0002] The amount of software code has an important impact on the progress of software development and the prospect of software application. Researchers have met the different needs of users by controlling the amount of software code (refer to patent number: ZL 03800635.9, the name of the invention "code amount control device and code Quantity control method" technical literature). At the same time, the amount of software code is directly related to the evolution of requirements in the software development process. Requirements evolution is the most likely to occur in software requirements development, and it is also an inevitable problem. Requirements evolution will lead to changes in the code amount of software projects. Processing ...

Problems solved by technology

[0008] When estimating the impact of the above two types of methods, it is necessary to first determine the code corresponding to the evolving requirements. For new requirements, it is impossible to establish an effective relationship between the new requirements and the existing code, so it is impossible to accurately estimate the new requirements. The amount of code that needs to be generated
