Abstract

Social coding platforms have revolutionized collaboration in software development, leading to using software bots for streamlining operations. However, The presence of open-source software (OSS) bots gives rise to problems including impersonation, spamming, bias, and security risks. Identifying bot accounts and behavior is a challenging task in the OSS project. This research aims to investigate bots' behavior in open-source software projects and identify bot accounts with maximum possible accuracy. Our team gathered a dataset of 19,779 accounts that meet standardized criteria to enable future research on bots in open-source projects. We follow a rigorous workflow to ensure that the data we collect is accurate, generalizable, scalable, and up-to-date. We've identified four types of bot accounts in open-source software projects by analyzing their behavior across 17 features in 5 dimensions. Our team created BotHawk, a highly effective model for detecting bots in open-source software projects. It outperforms other models, achieving an AUC of 0.947 and an F1-score of 0.89. BotHawk can detect a wider variety of bots, including CI/CD and scanning bots. Furthermore, we find that the number of followers, number of repositories, and tags contain the most relevant features to identify the account type., Comment: Dataset, Bots Detection, Classification.

Abstract

The objective of this study is to investigate the factors that contribute to brittleness and to identify strategies for mitigating these factors in populations with varying degrees of thermal vulnerability, based on the potential impact of extreme heat exposure on human survival and habitability. The physiological condition of lower adaptability to high temperature environments and the assessment of individuals who may have higher tolerance time in high temperature environments based on spatial perspectives suggest the need for targeted spatial optimization strategies for commuters and disadvantaged populations. This is demonstrated through a case study. These optimization measures encompass a variety of aspects, including the integration of transportation systems, the expansion of grey space corridors, the improvement of green space layout, and the implantation of green infrastructure. The study aims to reduce the exposure time of thermally vulnerable individuals to high temperature environments through spatial optimization strategies, to enhance the resilience of urban green spaces to heat stress, and to reduce the probability of heat-wave occurrence.

Abstract

The widespread development and adoption of open-source software have built an ecosystem for open development and collaboration. In this ecosystem, individuals and organizations collaborate to create high-quality software that can be used by everyone. Social collaboration platforms like GitHub have further facilitated large-scale, distributed, and fine-grained code collaboration and technical interactions. Countless developers contribute code, review code, report bugs, and propose new features on these platforms every day, generating a massive amount of valuable behavioral data from the open collaboration process. This paper presents the design and implementation of OpenDigger, a comprehensive data mining and information service system for open collaboration in the digital ecosystem. The goal is to build a data infrastructure for the open-source domain and promote the continuous development of the open-source ecosystem. The metrics and analysis models in the OpenDigger system can mine various knowledge from the macro to micro levels in the open-source digital ecosystem. Through a unified information service interface, OpenDigger provides various open-source information services to different user groups, including governments, enterprises, foundations, and individuals. As a novel information service system in the open-source ecosystem, this paper demonstrates the effectiveness of the metrics and models in OpenDigger through several real-world scenarios, including products, tools, applications, and courses. It showcases the significant and diverse practical applications of the metrics and models in both algorithmic and business aspects., Comment: in Chinese language
