We then verified our Twitter-related research outcomes using police crash reports. Sentiment and emotion analysis using classified tweets (with a 92% classification accuracy and 0.68 F1-score) showed somewhat negative emotions towards roadway WZs and onsite physical elements. However, the overall sentiment and emotion scores support the positive outcomes of WZ activities. We also found a strong temporal relationship between WZ-related tweets and fatalities. A cross-analysis of tweets and crash reports revealed that certain physical elements (e.g., signs, barriers, barrels, closures, and workers) are strongly associated with severe crashes at WZs. The results of this study may help policymakers to make appropriate policy decisions to improve driving experience and reduce WZ-related traffic accidents.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"8 4","pages":"Pages 458-473"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145885608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study constructs a prediction model for social media data identifiability of users based on a supervised machine learning technique. The findings, based on data from Weibo, a Chinese social media platform, indicate that the top seven features and values for predicting social media identifiability include blog pictures (0.21), blog location (0.14), birthdate (0.12), location (0.10), blog interaction (0.10), school (0.08), and interests and hobbies (0.07). The relationship between machine-predicted and self-reported identifiability was tested using data from 91 participants. Based on the degree of deviation between the two, users can be divided into four categories—normal, conservative, active, and atypical—which reflect their sensitivity to privacy concerns and preferences regarding information disclosure.

Furthermore, we examine the time efficiency of these “state-of-the-art” imputation methods considering the time-sensitive nature of certain machine learning applications. Utilizing ten real-world datasets, we introduced missingness at rates ranging from approximately 5%–75% under the MCAR, missing at random (MAR), and missing not at random (MNAR) mechanisms. We subsequently address missing data using five methods: complete case analysis (CCA), mean imputation, hot deck imputation, regression imputation, and multiple imputation (MI). Statistical tests are conducted on the machine learning outcomes, and the findings are presented and analyzed. Our investigation reveals that in nearly all scenarios, CCA performs comparably to MI, even with substantial levels of missingness under the MAR and MNAR conditions and with missingness in the output variable for regression problems. Under some conditions, CCA surpasses MI in terms of its performance. Thus, given the considerable computational demands associated with MI, the application of CCA is recommended within the broader context of supervised machine learning, particularly in big-data environments.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"8 3","pages":"Pages 361-373"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144931740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel surrogate-assisted optimization framework is employed, incorporating key performance metrics such as fuel efficiency and emissions to develop data-driven surrogate models of the EMS. These models are optimized using various algorithms targeting parameters such as engine idle speed, thermostat temperature fraction, regeneration load factor, and battery state-of-charge thresholds. Correlation analysis highlights the significant impact of the lower state-of-charge threshold and thermostat temperature fraction on fuel efficiency and emissions. Among the optimization methods, the combination of a backpropagation neural network (BPNN) and a multi-objective genetic algorithm (MOGA) proves most effective, achieving fuel consumption reductions of 5.26% and 5.01% in charge-sustaining and charge-depletion modes, respectively.

However, data pertaining to traffic flow are typically influenced by a multitude of factors, resulting in data that exhibit a considerable degree of nonlinearity and complexity. To address the issue of noise in raw traffic flow data, this study proposes a hybrid model that combines variational mode decomposition (VMD), a bidirectional long short-term memory network (BiLSTM), and a gated recurrent unit (GRU) for short-term traffic flow prediction. To validate the effectiveness of the model, an experimental validation was conducted based on traffic flow data from UK highways, and the performance of the model was compared with common benchmark models. The experimental results demonstrate that the proposed method yields superior prediction results in terms of mean absolute error, coefficient of determination, and root-mean-square error compared to existing prediction techniques, thereby substantiating its efficacy in short-term traffic flow prediction.</div></div>","PeriodicalId":100353,"journal":{"name":"Data Science and Management","volume":"8 3","pages":"Pages 257-269"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144866430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
