The project explores a theory of open source software (OSS) evolution based on statistical natural language processing techniques. Based on the emerging recognition that software code is, in many ways, as "natural" as natural language (e.g., English), there is a trend to apply statistical models for software development tasks such as code analysis, comprehension, and programmer support. This grant extends the "naturalness of code" theory by studying how the code lexicon evolves in open source software as different developers work on a software project and features are added, modified, deleted. The goal is to learn the extent to which the evolution of a developer's lexicon follows the laws of natural language evolution.To create the needed demonstration, large datasets of code lexicons are being collected from a large number of OSS projects and their revisions (on GitHub and SourceForge). The main constructs of the frequency model of natural language evolution will be applied to track and identify the main patterns of language changes (e.g., birth, propagation, death of terms in the lexicon) throughout OSS projects life cycle. Part of the challenge is to better understand how events that instigate code evolution, such as maintenance activities and team formation, are fundamentally different from the events that instigate change in natural language, such as war and migration. The research should lead to new ways to predict software project outcomes and to improve software productivity and quality. The project will make available the data, tools, and algorithms that will be produced by the project, which will support future work to understand the dynamics of code evolution in open source software ecosystems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目探讨了一种基于统计自然语言处理技术的开源软件（OSS）演化理论。基于新出现的认识，即软件代码在许多方面都像自然语言（例如英语）一样，将统计模型应用于软件开发任务（例如代码分析，理解和程序员支持）的趋势。该赠款通过研究代码词典在开源软件中如何发展的“代码的自然性”理论扩展了“代码的自然性”理论，并且随着不同的开发人员在软件项目上工作，并添加，修改，删除了功能。 目的是了解开发商词典遵循自然语言进化定律的演变的程度。为了创建所需的演示，正在从大量的OSS项目及其修订中（在Github和Sourceforge上）收集大量代码词典数据集。自然语言演化的频率模型的主要构造将用于跟踪和确定语言变化的主要模式（例如，出生，传播，词典中的术语死亡）整个OSS项目生命周期。挑战的一部分是更好地了解启动代码演变的事件（例如维护活动和团队形成）与促进自然语言变化（例如战争和移民）的事件的根本不同。该研究应导致预测软件项目成果并提高软件生产率和质量的新方法。该项目将提供该项目将生产的数据，工具和算法，该算法将支持未来的工作，以了解开源软件生态系统中代码演变的动态。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的审查审查标准来通过评估来通过评估来支持的。
