We propose a practical approach and the first open-source tool, GIDroid for multi-objective automated improvement of Android apps. In particular, we use Genetic Improvement, a search-based technique that navigates the space of software variants to find improved software. We use a simulation-based testing framework to greatly improve the speed of search. GIDroid contains three state-of-the-art multi-objective algorithms, and two new mutation operators, which cache the results of method calls. Genetic Improvement relies on testing to validate patches. Previous work showed that tests in open-source Android applications are scarce. We thus wrote tests for 21 versions of 7 Android apps, creating a new benchmark for performance improvements. We used GIDroid to improve versions of mobile apps where developers had previously found improvements to runtime, memory, and bandwidth use. Our technique automatically re-discovers 64% of existing improvements. We then applied our approach to current versions of software in which there were no known improvements. We were able to improve execution time by up to 35%, and memory use by up to 33% in these apps.\u0000</p></div>","PeriodicalId":55414,"journal":{"name":"Automated Software Engineering","volume":"32 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10515-024-00472-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In this paper, we propose ContractSentry, a tool for static analysis of smart contracts.

To bridge these gaps, we have assembled a comprehensive dataset that includes not only the primary factors identified in previous studies but also additional pertinent data. Utilizing this dataset, we assessed the impact of various factors and their representations on two leading computational approaches: fine-tuning pre-trained models and using prompts in large language models. Our investigation also examines the potential benefits and drawbacks of incorporating abstract syntax trees to represent code change structures. Our results reveal that: (1) the impact of factors varies between computational paradigms and their representations can have complex interactions; (2) integrating a code structure graph can enhance the graphing of code content, yet potentially impair the understanding capabilities of language models; and (3) strategically combining factors can elevate basic models to outperform those specifically pre-trained for tasks.

Additionally, we employ the innovative Ant-Colony Optimization algorithm (ACO) for feature selection, extracting pertinent features to amplify model performance. Recognizing the limitations of individual machine learning models, we introduce the Dynamic Classifier, a ground-breaking ensemble that combines predictions from multiple algorithms, elevating fault prediction precision.

However, finding user reviews that are valuable and relevant for quality improvement and app enhancement is challenging because of increasing end-user feedback. Also, to date, according to our knowledge, the existing sentiment analysis approaches lack in considering sarcasm and its types when identifying sentiments of end-user reviews for requirements decision-making. Moreover, no work has been reported on detecting sarcasm by analyzing app reviews. This paper proposes an automated approach by detecting sarcasm and its types in end-user reviews and identifying valuable requirements-related information using natural language processing (NLP) and deep learning (DL) algorithms to help software engineers better understand end-user sentiments. For this purpose, we crawled 55,000 end-user comments on seven software apps in the Play Store. Then, a novel sarcasm coding guideline is developed by critically analyzing end-user reviews and recovering frequently used sarcastic types such as Irony, Humor, Flattery, Self-Deprecation, and Passive Aggression. Next, using coding guidelines and the content analysis approach, we annotated the 10,000 user comments and made them parsable for the state-of-the-art DL algorithms. We conducted a survey at two different universities in Pakistan to identify participants’ accuracy in manually identifying sarcasm in the end-user reviews. We developed a ground truth to compare the results of DL algorithms. We then applied various fine-tuned DL classifiers to first detect sarcasm in the end-user feedback and then further classified the sarcastic reviews into more fine-grained sarcastic types. For this, end-user comments are first pre-processed and balanced with the instances in the dataset. Then, feature engineering is applied to fine-tune the DL classifiers. We obtain an average accuracy of 97%, 96%, 96%, 96%, 96%, 86%, and 90% with binary classification and 90%, 91%, 92%, 91%, 91%, 75%, and 89% with CNN, LSTM, BiLSTM, GRU, BiGRU, RNN, and BiRNN classifiers, respectively.

Therefore, the input code coverage matrix plays a crucial role in FL. However, the effectiveness of fault localization is compromised by the presence of coincidental correct test cases (CCTC) in the coverage matrix. These CCTC execute faulty code but do not result in program failures. To address this issue, many existing methods focus on identifying CCTC through cluster analysis. However, these methods have three problems. Firstly, identifying the optimal cluster count poses a considerable challenge in CCTC detection. Secondly, the effectiveness of CCTC detection is heavily influenced by the initial centroid selection. Thirdly, the presence of abundant fault-irrelevant statements within the raw coverage matrix introduces substantial noise for CCTC detection. To overcome these challenges, we propose SCD4FL: a semantic context-based CCTC detection method to enhance the coverage matrix for fault localization. SCD4FL incorporates and implements two key ideas: (1) SCD4FL uses the intersection of execution slices to construct a semantic context from the raw coverage matrix, effectively reducing noise during CCTC detection. (2) SCD4FL employs an expert-knowledge-based K-nearest neighbors (KNN) algorithm to detect the CCTC, effectively eliminating the requirement of determining the cluster number and initial centroid. To evaluate the effectiveness of SCD4FL, we conducted extensive experiments on 420 faulty versions of nine benchmarks using six state-of-the-art fault localization methods and two representative CCTC detection methods. The experimental results validate the effectiveness of our method in enhancing the performance of the six fault localization methods and two CCTC detection methods, e.g., the RNN method can be improved by 53.09% under the MFR metric.</p></div>","PeriodicalId":55414,"journal":{"name":"Automated Software Engineering","volume":"31 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142198469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In reality, there won’t be adequate software fault data for a recently established project where the Cross-Project Fault Prediction (CPFP) model plays an important role. CPFP model utilizes other finished projects data to predict faults in ongoing projects. Existing CPFP methods concentrate on discrepancies in distribution between projects without exploring relevant source projects selection combined with distribution gap minimizing methods. Additionally, performing imbalance learning and feature extraction in software projects only balances the data and reduces features by eliminating redundant and unrelated features. This paper proposes a novel SRES method called Similarity and applicability based source projects selection, REsampling, and Stacked autoencoder (SRES) model. To analyze the performance of relevant source projects over CPFP, we proposed a new similarity and applicability based source projects selection method to automatically select sources for the target project. In addition, we introduced a new resampling method that balances source project data by generating data related to the target project, eliminating unrelated data, and reducing the distribution gap. Then, SRES uses the stacked autoencoder to extract informative intermediate feature data to further improve the prediction accuracy of the CPFP. SRES performs comparable to or superior to the conventional CPFP model on six different performance indicators over 24 projects by effectively addressing the issues of CPFP. In conclusion, we can ensure that resampling and feature reduction techniques, along with source projects selection can improve cross-project prediction performance.</p></div>","PeriodicalId":55414,"journal":{"name":"Automated Software Engineering","volume":"31 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142198467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
