Jupyter notebook study accepted in EMSE
Our paper “An Empirical Comparison of Jupyter Notebooks in Kaggle and GitHub Data Science Projects” has been accepted in Empirical Software Engineering (EMSE), a Q1 journal. Data scientists widely use computational notebooks to share knowledge, practice skills, and collaborate, but there are few practical guidelines for writing a good notebook. The team analyzed 7,987 Kaggle notebooks and 2,342 GitHub notebooks, comparing 33 features of each notebook. As Kaggle contributors rise in rank, their notebooks tend to become more elaborate and better documented rather than more concise, though the effects are small. The study began with Tasha Settewong's research internship at the Software Engineering Laboratory of NAIST in 2021 and grew through an APSEC 2022 paper and an MSR 2023 registered report.

PhD thesis proposal defense
Our doctoral student Dan M. Kazimoto defended a PhD thesis proposal titled “An AI-Agentic Model for Predicting and Explaining Software Release Outcomes in the Era of AI Coding Agents” on 23 July 2026. AI coding agents such as GitHub Copilot, Claude Code, and OpenAI Codex now write code for software projects as teammates. The proposed model forecasts the productivity and quality of a software release, explains each forecast in terms a team can check, and stays valid when AI agents contribute. It also introduces the AI-inclusive bus factor, an ownership measure that counts AI agents alongside people. Asst. Prof. Dr. Morakot Choetkiertikul advises the thesis, with Suppawong Tuarob and Thanwadee Sunetnanta as co-advisors, and Mahidol University's Faculty of Graduate Studies approved the thesis title on 11 August.

MSR 2026 Mining Challenge paper
Our paper “When is Generated Code Difficult to Comprehend? Assessing AI Agent Python Code Proficiency in the Wild” was accepted in the Mining Challenge track of MSR 2026, held in Rio de Janeiro, Brazil, in April 2026. AI coding agents now write much of the code that developers review, so the team asked how advanced that code is. They mined 591 pull requests with 5,027 Python files written by three AI agents and rated each construct with pycefr, on six levels from A1 (Basic) to C2 (Mastery). Over 90% of the constructs fell into the two basic levels and under 1% reached Mastery, a profile close to that of human pull requests. Nanthit Temkulkiat, the first author, was a 2025 summer intern at The University of Osaka.

NPC tool accepted at ICAART 2026
NPC, a tool built by our students Pachanitha Saeheng, Napat Boongaree, and Chutweeraya Sriwilailak, was accepted for publication at ICAART 2026, the 18th International Conference on Agents and Artificial Intelligence. NPC detects code snippets generated by ChatGPT and explains each decision, using machine learning with a local neighborhood sampling strategy that the team proposed for post-hoc explanations. It runs as a web application and gives educators an easy-to-understand explanation for each classification. Professors who evaluated the tool found the explanations clear and helpful, which suggests it can support academic integrity in programming education. Dr. Chaiyong Ragkhitwetsagul, Dr. Teeradaj Racharak of Tohoku University, and Dr. Ekapol Chuangsuwanich of Chulalongkorn University co-supervised the project, which began during a 2024 research internship at JAIST.

SECURITY.md study accepted in EMSE
Our paper “Security by Documentation? Characterizing GitHub SECURITY.md Policy and Their Adoption in Python Libraries” has been accepted in Empirical Software Engineering (EMSE), a Q1 journal. Many open-source projects publish a SECURITY.md file that tells users how to report vulnerabilities. Earlier studies counted how many projects adopt such a policy, but they did not examine what the policies say. The study analyzed the security policies of 679 Python libraries from PyPI hosted on GitHub and found that projects with a SECURITY.md file follow recommended security practices more closely. The work grew from internship research by our bachelor's students, with partners at NAIST and The University of Osaka.

Sprint2Vec in the ASE 2025 Journal-First track
Our IEEE TSE paper “Sprint2Vec: A Deep Characterization of Sprints in Iterative Software Development” was accepted in the Journal-First track of ASE 2025. Sprint2Vec builds vector representations of Agile sprints from structured data, such as sprint reports, issue attributes, and developer profiles, and from text, such as issue descriptions and sequences of developer activity. Unlike earlier methods that predict only how much a sprint delivers, it predicts both productivity and quality, where quality means the risk of reopened issues. The evaluation covered nearly 8,000 sprints, 118,000 issues, and 3.7 million developer activities across five large open-source projects, where Sprint2Vec beat baseline and state-of-the-art approaches.

Internship study accepted at ISE 2025
A study by Chayanid Termphaiboon from a research internship at NAIST was accepted at the International Workshop on Intelligent Software Engineering (ISE 2025), co-located with ASE 2025. It compared Python projects on PyPI with and without a SECURITY.md file to see how security policies relate to dependency management. Projects with a security policy tend to rely on a broader set of direct dependencies, while the depth of their dependency chains is similar. Projects created after SECURITY.md was introduced, especially later adopters, update their dependencies more often. The results suggest that security policies go with more modular projects and more proactive dependency management.

Thai tool adoption study in the ICSME 2025 Journal-First track
Our EMSE study on how software companies in Thailand adopt automated software engineering tools was accepted in the Journal-First track of ICSME 2025, the International Conference on Software Maintenance and Evolution. The study asked how small and medium-sized software enterprises adopt tools for software measurement, static code analysis, continuous integration, and software testing. Based on a survey of 103 Thai developers, it found that developers are generally familiar with these tools and see their benefits. A lack of knowledge or experience holds back measurement and static analysis tools, continuous integration is used with some difficulty, and manual testing remains common. We call for easier tools that lower the barrier for such companies in developing countries.

Autorepairability at SANER 2024
Pongpop Lapvikai presented “Autorepairability: A New Software Quality Characteristic” in the ERA track of SANER 2024 in Finland. It comes from Pongpop's 2023 summer internship at the Software Engineering Lab of Osaka University, under the supervision of Prof. Yoshiki Higo. The paper proposes autorepairability as a new characteristic of software quality, meaning the degree to which automated program repair can be applied to a piece of software. Chutweeraya Sriwilailak's APSEC 2024 paper took the idea further by comparing the autorepairability of ChatGPT and Gemini.

Thai tool adoption study accepted in EMSE
Our paper “Adoption of automated software engineering tools and techniques in Thailand” was accepted in Empirical Software Engineering (EMSE), a Q1 journal. It looks at how aware Thai small and medium-sized software companies are of automated software engineering tools, how far they adopt them, and what challenges they meet, for software measurement, static code analysis, continuous integration, and software testing. We surveyed 103 Thai developers across four groups. The main challenges were a lack of knowledge and experience, long build times in continuous integration, and an emphasis on development over testing. The paper is the second publication of the Newton Fund project “Automated Software Engineering for Thailand Software Industry”, a collaboration between CREST at UCL and SERU since 2018.

New SERU Logo
We redesigned a new logo for our SERU research group to celebrate the coming 5th year anniversary (the first commit on the SERU website was on 19 October 2018!). Compared to the previous logo, this one has only the "S" to represent the research group. This is to strive for a more modern and minimal design.
We still keep the oceanic green and cream colors to represent the Faculty of ICT and the dark blue color represents Mahidol University. The composition of the S consists of two components lightly connected to each other, like software, its fast-changing nature, and its dependencies 😉.
We would like to thank Miss Sirirat Wittayakunsatid, Audio Visual and Digital Learning Media Development Division at the Faculty of ICT, for her great design work!

Newton Fund project wraps up
Dr. Jens Krinke of University College London (UCL) and Chaiyong Ragkhitwetsagul visited three of our industry partners, Roots, CourseSquare, and ProGaming, to conclude the project “Automated Software Engineering for Thailand Software Industry”. Over four years, the project studied the software engineering challenges of Thai software SMEs, their awareness and adoption of automated software engineering tools and techniques, and how SonarQube and unit testing can benefit them. The findings show that these companies work under several constraints that hold back their adoption of advanced techniques, so they still need to adopt the basic ones fully first. Both the researchers and the companies learned a lot from the project and look forward to working together again.

Café SERU No. 8, back on site
Assoc. Prof. Dr. Jens Krinke, Director of CREST at University College London, gave Café SERU No. 8, “Toxic Code on Stack Overflow”, on 16 November 2022 in room A2 of the MU AI Center. It was our first seminar on site since the COVID-19 pandemic. Developers exchange code snippets on Stack Overflow, and researchers harvest those snippets for recommendation systems, but the code can have quality problems such as security or license issues. The talk covered how Stack Overflow users perceive such issues, the problem of outdated code and possible license violations, and code on Stack Overflow that breaks coding style and contains security problems. Such toxic code may affect both the projects that reuse it and the mining or machine learning work that uses Stack Overflow as a code base.

Café SERU No. 7 on third-party library quality
Dr. Bodin Chinthanet, a specially appointed assistant professor in the Software Engineering Laboratory at NAIST, gave Café SERU No. 7 as an online lunchtime talk on 5 April 2022. His talk, “Characterizing the Quality of Third-party libraries through Runnability and Risk Assessment in the Open Source Ecosystem”, had two parts. The first asked how developers choose a good package and found, through a developer survey and an analysis of runnability, that users and contributors judge package quality in similar ways, with runnability as a useful guide. The second looked at security risk and found that the delay in adopting a vulnerability fix depends on factors such as severity and freshness, while most vulnerable code is not reachable from the application.

Software SME challenges at SANER 2022
Chaiyong Ragkhitwetsagul presented “Identifying Software Engineering Challenges in Software SMEs: A Case Study in Thailand” in the Industry Track of SANER 2022, the IEEE International Conference on Software Analysis, Evolution and Reengineering, which CORE ranks A. Through semi-structured interviews with four small and medium-sized software enterprises in Thailand, the study found common challenges such as a lack of testing, code-related issues, and inaccurate effort estimation. Before such companies can bring in advanced automated software engineering tools, they need to adopt current best practices such as automated testing, continuous integration, and automated code review. The paper also suggests that researchers engage with these companies to help them learn and adopt better practices.

Café SERU No. 5, our first online talk
Café SERU went online for the first time on 19 August 2020, with Dr. Hideaki Hata's talk “Software Documentation and Software Economics for Knowledge Sharing” on Zoom and live on our Facebook page. Source code often points to outside knowledge such as Stack Overflow threads, issue discussions, and academic papers, and Dr. Hata's studies of software documentation found problems such as decaying links and obsolete knowledge. Because this knowledge is shared across whole software ecosystems, the talk explored economic mechanisms similar to bug bounty programs to address these problems. Dr. Hata co-supervised two senior projects of our students during their NAIST internships, which led to the FixMe bot at ASE 2021 and a Gitcoin study in the Journal of Systems and Software.

Toxic code snippets at ESEC/FSE 2019
Chaiyong Ragkhitwetsagul presented “Toxic Code Snippets on Stack Overflow” on 29 August 2019 at ESEC/FSE 2019, the ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering, in Tallinn, Estonia. The paper appeared in IEEE Transactions on Software Engineering (TSE), and the conference accepted it for a journal-first presentation. Code copied to Stack Overflow as an example is not checked afterwards, so it can become toxic, for example by going out of date or by violating the license of the original code. The study combined two developer surveys with large-scale clone detection between 72,365 Java snippets on Stack Overflow and 111 open-source projects. Of the 201 high-reputation answerers who took part in the first survey, 69 percent said they never check for license conflicts between the code they copy and Stack Overflow's CC BY-SA 3.0 license.

Café SERU No. 2 on interpretable AI
Dr. Teeradaj Racharak of the Japan Advanced Institute of Science and Technology (JAIST) gave Café SERU No. 2, “Interpretable Artificial Intelligence”, on 17 June 2019 in room IT405. Interpretable AI covers techniques that people can trust and understand easily, so that a system can explain why it reached a decision instead of acting as a black box. The talk introduced the basics of computational logic, namely syntax, semantics, and proof theory, and related them to knowledge representation and to the transparency of AI decisions. It stirred up several follow-up discussions. Dr. Racharak later hosted SERU interns at JAIST and Tohoku University and co-authored several of our papers, including those at NLDB 2025 and APSEC 2025.

Scrum and Git training
SERU ran hands-on training for software teams in 2019. On 17 April, Thanwadee Sunetnanta led a LEGO Scrum session for the Information Systems (IS) team of the Faculty of ICT, which wanted to move its software development to Scrum. With LEGO blocks as a metaphor for building software, the team built a city to the customer's requirements over several rounds of Scrum meetings and sprints. In May, the faculty chose Thanwadee to lead the training on agile software development best practices in its new professional program, Retraining and Coaching ICT Professionals. On 14 June, Morakot Choetkiertikul and Chaiyong Ragkhitwetsagul gave the IS team a workshop on managing software projects with Git and collaborating through GitHub.

Café SERU begins
We launched Café SERU, our series of software engineering seminars, on 11 June 2019 in room IT405 of the ICT Building. The first session looked at the future of software defect prediction and software quality with two invited speakers. Dr. Chakkrit (Kla) Tantithamthavorn of Monash University talked about explainable artificial intelligence that predicts future software defects and explains why code is defective, so that teams can spend their limited quality assurance effort where it matters most. Dr. Patanamon (Pick) Thongtanunam of the University of Melbourne talked about the practices that affect quality in software development. The talks were open to anyone, and the series reached its twelfth session in August 2024.

Summer internships 2019
Four of our undergraduate students spent the summer of 2019 on research internships abroad. Thanadon Bunkerd, Noppadol Assavakamhaenghan, and Tattiya Sakulniwat joined the Software Engineering Laboratory of Prof. Kenichi Matsumoto at NAIST for two and a half months, and Vara Arammongkolvichai went to the University of Bremen in Germany. Before leaving, the NAIST group met Prof. Matsumoto in March, and in April SERU staff discussed possible research topics for them with four professors of the laboratory over Skype. They received Mahidol University's Scholarship for Undergraduate Student Mobility Program (30,000 baht) to support their stay in Japan. All four internships became papers at IWESEP 2019 in Tokyo that December.

ISO/IEC 29110 expert certificates
SERU members completed the ISO/IEC 29110 and ISO/IEC 15504 (33000) expert training course for consultants, auditors, and lecturers, passed its qualifying exam, and received their certificates on 11 May 2019. The certificates make them eligible to work as consultants who help organizations implement ISO/IEC 29110. This series of standards defines software engineering lifecycle profiles for very small entities (VSEs), such as small software companies. Morakot Choetkiertikul has since advised Thai software companies on ISO/IEC 29110 certification. The standard also shaped TraceCraft, a student tool for ISO/IEC 29110 traceability presented at InCIT 2025.
