These characteristics, however, make the development of blockchain-based applications demanding and costly. Model-driven development (MDD) offers a paradigm by abstracting low-level details into higher level models, thereby potentially enhancing efficiency and reducing errors. Yet, existing MDD-based solutions are fragmented and lack comprehensive support for the software development lifecycle (SDLC) in a consistent manner. Moreover, the intrinsic complexity of blockchain and its heterogeneous infrastructures introduces further challenges across SDLC stages, highlighting the need for a unified framework that systematically integrates MDD with blockchain-specific development. This research proposes an MDD-based reference framework that supports a consistent modeling process across the entire SDLC of blockchain-based applications, from requirements to deployment. The framework adapts various modeling techniques to address blockchain-specific features such as decentralization, one-time smart-contract deployment, and immutable data record. The model transformation methods are improved to support the seamless full SDLC development process of blockchain-based systems. The proposed reference framework is platform independent at modeling level, enabling compatibility with heterogeneous blockchain platforms. Its adaptability was validated through a prototype implementation supporting both Ethereum and Hyperledger Fabric. Further, a comparative case study was conducted on a cross-border food supply chain. The results demonstrate the feasibility and adaptability of the MDD-based reference framework, as well as improved efficiency for blockchain-based system development, which promotes a broader adoption of blockchain technology.</p>\u0000 </div>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 6","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148128171","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}

These elements help developers identify, reproduce, and fix software bugs. Manually identifying them in large bug reports is time-consuming, so automation is needed. However, existing methods mainly rely on features extracted from individual sentences and neglect contextual information, which leads to poor performance in bug report sentence classification. To address this problem, we construct a semantic knowledge base to capture contextual information and then employ a multidimensional fusion strategy to integrate features from multiple sources for bug report sentence classification. The semantic knowledge base consists of three components: a keyword co-occurrence matrix, synonym sets, and causality pair sets, which together capture contextual information. We then fuse the semantic knowledge base features with BERT word embeddings through a cross-attention mechanism, followed by the concatenation of discourse pattern features to improve classification accuracy. We evaluated our method on a context-dependent dataset, achieving an accuracy of 73.4% and a Hamming loss of 0.167. Experimental results indicate that AIBRD outperforms existing methods. Compared with the state-of-the-art baseline DEMIBuD-H, AIBRD improves macro-average accuracy by 3.3% and macro-average F1 score by 7.0%.</p>\u0000 </div>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 6","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148128168","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}

Among these, copyright-related terms are especially critical. Ensuring compliance with such terms is challenging due to the widespread use of third-party libraries and the diversity of license types. While license-related issues have attracted research interest, most prior work targets a narrow set of licenses and often overlooks copyright terms. To bridge this gap, we propose an automated approach for detecting copyright term violations in open-source projects that incorporate third-party libraries, covering a wide range of Open Source Initiative-approved licenses. Our method extracts licenses from both projects and their dependencies, uses large language models to interpret key copyright terms, and identifies potential violations. We applied our approach to 500 popular Python projects on GitHub and found that about 10% exhibited at least one violation. These results highlight the complexity of third-party license management and the need for improved compliance tools. By analyzing tens of thousands of licenses, we also uncovered common patterns in license usage. To foster further research and promote proactive compliance, we release our tool and dataset to the community.</p>\u0000 </div>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 6","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148128166","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}

BPMN has been extended to represent particular domains or application areas, or to improve practical aspects. BPMN extensions have been the subject of recent studies. This study aims to identify and analyze the BPMN extensions proposed between 2019 and 2025 (until July). This paper followed the steps of a systematic literature review (SLR) to identify and analyze the BPMN extensions. We first performed automatic and manual search and selection process to obtain the primary studies. We also selected papers using forward and backward snowballing techniques. In this analysis, we checked whether the studies reviewed presented clear meaning for the new extended constructs, including name, formal description, purpose, and application in the proposed context. The research identified 84 studies that resulted in new BPMN extensions, analyzing essential attributes, application areas, type of extension, syntax level, and adherence to Object Management Group (OMG) standards. The results showed that 95.7% of the extensions do not preserve the original BPMN syntax, and 55% do not support the modeling of the new elements, making their adoption difficult. In addition, we found that the presentation of the extensions lacks standardization: 55% of the studies do not provide meaning, 18.8% present partial definitions, and only 26.3% offer complete and structured descriptions. These findings reinforce the need for more consistent guidelines for defining and implementing BPMN extensions, contributing to future research into the extensibility of the notation. In this paper, we presented the results of an updated SLR to identify BPMN extensions. Our goal was to improve the understanding of how BPMN has been extended through evidence in literature. We identified 84 papers that extended BPMN in the last years (2019–2025), and five research questions were answered and discussed.</p>","PeriodicalId":48898,"journal":{"name":"Journal of Software-Evolution and Process","volume":"38 6","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/smr.70127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148128209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
