The reliable design of online examination systems is crucial to ensuring the correctness of examination procedures.

To address this gap, we use colored Petri nets (CPNs), which enable end-to-end modeling of concurrent processes and data-token interactions. In this paper, we develop a comprehensive CPN-based framework to model the entire online examination workflow. We formalize eight critical properties (e.g., correct total score) using ASK-CTL and verify them through state-space exploration and scenario simulation in CPN Tools. The verification results demonstrate that the model satisfies all eight properties, with no deadlocks or property violations found among 62,292 state-space nodes.

Based on semi-structured interviews with experienced Agile team leaders, the study reveals that Agile ceremonies alone are indeed insufficient to ensure the knowledge sharing and common ground necessary for efficient collaboration. The findings highlight the need to distinguish communication purposes across stakeholder roles, introducing the concept of role-based communication interfaces as a means of strengthening shared understanding of objectives, requirements, and priorities. By viewing Agile teams as social systems, this study identifies targeted strategies to mitigate process loss through structured, purpose-driven communication frameworks.

For program slicing, existing research focuses on dependency analysis during slicing while lacking the selection of slicing criteria before slicing. As the starting point of dependency analysis, the slicing criterion directly determines the results of the program slicing application. However, existing criterion selection is only based on empirical judgment and lacks an effective slicing criterion selection method. In this paper, we propose PSCSelector, an appropriate Program Slicing Criterion Selection framework based on a popular lightweight LLM CodeBERT. PSCSelector first constructs the detailed substatement level system dependency graph to obtain the context of the slicing criterion. CodeBERT is then fine-tuned in a parameter-efficient way to jointly embed the slicing criterion context and the application texts to capture the appropriate criterion pattern. To validate the effectiveness of PSCSelector in downstream tasks, we choose bug localization as the example application and build the corresponding PSCSelector. In the experiment, we evaluate the effectiveness of PSCSelector in bug dataset Defects4J by calculating the number of searched bugs and the size of the search scope. The experimental results show that the PSCSelector-selected slicing criterion can effectively search 74% of bugs and reduce 69% of the original slice, which uses the bug-triggering statement as the slicing criterion.</p>\u0000 </div>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manually extracting such artifacts from PDF-based standards is time-consuming and error-prone. To address this issue, we developed a large language model (LLM)-based approach for automatically generating artifact models from standards. However, the evolution of AI models constitutes a challenge, since the extraction results might differ when updating the LLM to a newer version.

The approach generates machine-readable artifact models that allow for automated measurement systems, for example, for monitoring compliance and controlling complex projects.

We conducted a four-round survey study with 81 students in team-based software projects. Across rounds, participants reported these factors and labeled 30 decontextualized statements for sentiment, including meta-data on labeling rationale and uncertainty. Our results show: (1) Sentiment perception is only moderately stable within individuals, and label changes concentrate on ambiguity-prone statements; (2) correlation-level signals are small and do not survive global multiple-testing correction; (3) in statement-level repeated-measures models (GEE), higher mood trait and reactivity are associated with more positive (and less neutral) labeling, while predictors of negative labeling are weaker and at most trend-level (e.g., task conflict); (4) we find no clear evidence of systematic project-phase effects.

The complexity and rapid growth of these projects pose significant challenges for maintenance within the open-source community. Given that NN architecture code is the core asset of NN projects, understanding its reuse in the open-source community is essential for effective maintenance, such as reducing redundancy and identifying potential intellectual property violations. While prior studies have examined code reuse in open-source projects, they have two key limitations: They do not specifically address NN structure code, and they rely on manually selected small-scale datasets that do not sufficiently represent the broader open-source ecosystem. To address these limitations, this study explores reuse patterns in a large-scale dataset of 20,000 open-source projects on GitHub, focusing specifically on NN structure code. Specially, we categorize NN structure reuse into three types: (1) exact reuse with no changes; (2) shallow reuse with minor adjustments like renaming variables or adjusting parameters; and (3) conceptual reuse with significant modifications, while retaining the same layer sequence. We then propose a detection framework, <i>NNReuse</i>, to identify these reuse types and conduct an empirical evaluation of their prevalence and characteristics. As a practical application, we also assess potential license conflicts based on <i>NNReuse</i>. Extensive experiments show that 55.6% of projects and 54.17% of NN structures exhibit structural similarities that are consistent with potential NN structure reuse in open-source projects. Among these, exact reuse is particularly common and introduces significant redundancy, with an estimated storage optimization potential of up to 34.49%. Reuse primarily occurs at a high level, with 43.3% involving the reuse of overall network architecture. Additionally, in projects with license protection, as much as 64.3% may present potential license conflicts, highlighting the importance of strengthened license compliance and proactive IP risk mitigation in the open-source community.</p>\u0000 </div>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147612881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fuzzing, a powerful technique for detecting vulnerabilities in operating systems, has increasingly been applied to the security analysis of TEEs. However, conventional fuzzing tools cannot be directly used for TEE kernels due to their isolation. Coverage-guided fuzzers often discard test cases that trigger new states but cover the same code, which limits their effectiveness in discovering vulnerabilities. To address these challenges, we propose a state-aware fuzzing method specifically designed for TEE kernels. Initially, we develop a modeling and tracing approach to represent the program state through state-variable values, overcoming the limitations of coverage-guided fuzzers. Subsequently, we propose a new communication scheme to address the issues resulting from the isolation of TEEs. Additionally, new seed preservation and selection algorithms are put forward to better guide the fuzzer in exploring vulnerabilities. Finally, we employ the N-gram model to enhance the test case generation process and optimize the framework's performance. We have implemented a prototype called Trusty-Statefuzz and evaluated it on Fuchsia, our self-developed microkernel operating system Nebula, and the OP-TEE. The evaluation results show that Trusty-Statefuzz is effective at detecting both new code and vulnerabilities. Trusty-Statefuzz discovers nine unknown vulnerabilities and 23 known vulnerabilities.
