Abstract: Objectives. In contemporary software development practice, version control systems are often used to manage the development process. Such systems allow developers to track changes in the codebase and convey the context of these changes through commit messages. The use of such messages to provide relevant and high-quality descriptions of the changes generally requires a high level of competence and time commitment from the developer. However, modern machine learning methods can enable the automation of this task. Therefore, the work sets out to provide a statistical and comparative analysis of the collected data sample with sets of changes in the program code and their descriptions in natural language. Methods. In this study, a comprehensive approach was used, including data collection from popular GitHub repositories, preliminary data processing and filtering, as well as statistical analysis and natural language processing method (text vectorization). Cosine similarity was used as a means of assessing the semantic proximity between the first sentence and the full text of commit messages. Results. A comprehensive study of the structure and quality of commit messages encompassed data collection from GitHub repositories and preliminary data cleansing. The research involved text vectorization of commit messages and evaluation of semantic similarity between the first sentences and full texts of messages using cosine similarity. The comparative analysis of message quality in the collected dataset and several analogous datasets used classification based on the CodeBERT model. Conclusions. The analysis revealed a low level of cosine similarity (0.0969) between the first sentences and full texts of commit messages, indicating a weak semantic relationship between them and refuting the hypothesis that first sentences serve as summaries of message content. The low proportion of empty messages in the collected dataset at 0.0007% was significantly lower than expected, indicating high-quality data collection. The results of classification analysis showed that the proportion of messages categorized as “poor” in the collected dataset was 16.82%, substantially lower than comparable figures in other datasets, where this percentage ranged from 34.75% to 54.26%. This fact underscores the high quality of the collected dataset and its suitability for further application in automatic commit message generation systems.
