Engineering teams need timely signals about evolving requirements and release risk, yet multilingual fan discourse around live sports is noisy, code-switched, and saturated with sarcasm and event-driven drift. We present Hybrid DeepSentX, an AI-driven framework that converts crowd commentary into actionable requirements insight and sprint-level risk scores. The pipeline couples multilingual transformer encoders with an inductive GraphSAGE conversation graph to inject relational context across posts, and adds a reinforcement learner whose reward is shaped to prioritize correct decisions on sarcasm-heavy items and rapidly shifting events. We assembled a million-plus posts from X, Reddit, and sports forums and evaluated the framework against strong baselines, including BERT, long short-term memory, support-vector machines, and recent hybrid models, with significance tests, calibration analysis, ablations, and efficiency profiling. DeepSentX achieved higher macro-averaged accuracy and F1 on code-switched and sarcastic subsets, reduced missed risk flags, and produced developer-facing artefacts that directly support backlog grooming and defect triage. Relative to prior hybrids that combine transformers with either graph reasoning or reinforcement alone, our contributions are fourfold: (i) a unified multilingual design that integrates transformer, graph, and reinforcement components for sarcasm and drift robustness, (ii) an annotated multi-platform corpus with explicit code switching and sarcasm labels and per platform language balance, (iii) a rigorous comparative study reporting accuracy, calibration, latency, memory, and parameter count, and (iv) deployment artefacts that turn model outputs into requirement clusters and sprint risk scores suitable for continuous planning.

工程团队需要关于不断变化的需求和释放风险的及时信号,然而围绕现场体育赛事的多语言粉丝话语是嘈杂的、代码切换的,并且充满了讽刺和事件驱动的漂移。我们提出了Hybrid DeepSentX,这是一个人工智能驱动的框架,可以将人群评论转换为可操作的需求洞察和冲刺级风险评分。该管道将多语言转换器编码器与一个归纳GraphSAGE对话图耦合在一起,以在帖子之间注入关系上下文,并添加了一个强化学习器,其奖励被塑造为优先考虑对讽刺重的项目和快速变化的事件的正确决策。我们从X、Reddit和体育论坛上收集了100多万篇帖子,并根据强大的基线(包括BERT、长短期记忆、支持向量机和最近的混合模型)对框架进行了评估,并进行了显著性测试、校准分析、消耗和效率分析。DeepSentX在代码切换和嘲弄子集上实现了更高的宏观平均精度和F1,减少了错过的风险标志,并产生了面向开发人员的工件,直接支持待办事项整理和缺陷分类。相对于之前将变压器与图形推理或单独强化相结合的混合动力车,我们的贡献有四个方面:(i)统一的多语言设计,集成了用于讽刺和漂移鲁棒性的变压器、图形和强化组件;(ii)带有明确代码切换和讽刺标签以及每个平台语言平衡的注释多平台语料库;(iii)严格的比较研究报告准确性、校准、延迟、内存和参数计数;(iv)部署工件,将模型输出转换为适合连续规划的需求集群和冲刺风险评分。

With the rapid development of social media and online platforms, the speed and influence of emergency dissemination in cyberspace have significantly increased. The swift changes in public opinion, especially the phenomenon of opinion reversals, exert profound impacts on social stability and government credibility. The hypernetwork structure, characterized by its multilayered and multidimensional complexity, offers a new theoretical framework for analyzing multiagents and their interactions in the evolution of public opinion. Based on hypernetwork theory, this study constructs a four-layer subnet model encompassing user interaction network, event evolution network, semantic association network, and emotional conduction network. By extracting network structural features and conducting cross-layer linkage analysis, an identification system for public opinion reversals in emergencies is established. Taking the donation incident involving Hongxing Erke during the Henan rainstorm in 2021 as a case study, an empirical analysis of the public opinion reversal process is conducted. The research results indicate that the proposed hypernetwork model can effectively identify key nodes in public opinion reversals. The multi-indicator collaborative identification system for public opinion reversals aids in rapidly and effectively detecting signals of such reversals. This study not only provides new methodological support for the dynamic identification of public opinion reversals but also offers theoretical references and practical guidance for public opinion monitoring and emergency response decision-making in emergencies.

随着社交媒体和网络平台的快速发展,突发事件在网络空间的传播速度和影响力显著提高。社会舆论的急剧变化,特别是舆论倒转现象,对社会稳定和政府公信力产生了深刻的影响。以多层次、多维复杂性为特征的超网络结构为分析舆论演变过程中的多智能体及其相互作用提供了一个新的理论框架。本研究基于超网络理论,构建了包含用户交互网络、事件演化网络、语义关联网络和情感传导网络的四层子网模型。通过提取网络结构特征,进行跨层联动分析,建立突发事件舆情逆转识别体系。以2021年河南暴雨期间红星尔克捐赠事件为例,实证分析舆论逆转过程。研究结果表明,所提出的超网络模型能够有效地识别舆情逆转的关键节点。舆论逆转多指标协同识别系统有助于快速有效地发现舆论逆转信号。本研究不仅为舆情逆转动态识别提供了新的方法支持,也为突发事件中舆情监测和应急决策提供了理论参考和实践指导。

Method for Power Grid Digital Operation Data Integration Based on K-Medoids Clustering with Support for Real-Time Cross-Modal Applications. 基于k -媒质聚类支持实时跨模态应用的电网数字化运行数据集成方法。
IF 2.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-01 DOI: 10.1177/2167647X251406607

Data in power grid digital operation exhibit multisource heterogeneous characteristics, resulting in low integration efficiency and slow anomaly detection response. To address this, this paper proposes a method for power grid digital operation data integration based on K-medoids clustering. The basic service layer utilizes an Field Programmable Gate Array parallel architecture. This enables millisecond-level synchronous acquisition and dynamic preprocessing of multisource data, such as mechanical vibration, partial discharge signals, and temperature. The implementation is based on the analysis of the power grid digital operation structure. The data are then fed back to the cloud service layer, which, through business integration services, data analysis, and data access services, performs data filtering and analysis. Subsequently, the data are input to the application layer via the database server. The application layer employs a K-medoids clustering method that introduces a density-weighted Euclidean distance metric and an adaptive centroid selection strategy, significantly enhancing the clustering performance of multisource data. In particular, the proposed architecture supports real-time data processing and can be extended to cross-modal scenarios, including integration with speech-to-text systems in power grid monitoring. By aligning with low-latency neural network principles, this method facilitates timely decision-making in intelligent operation environments. Experiments confirm the method's efficacy. It acquires and integrates multisource heterogeneous power grid digital operation data effectively. The data throughput of different power grid digital operation data sources all exceed 110 MB/s. The silhouette coefficient of the integrated data sets is greater than 0.91, indicating that the integration of power grid digital operation data using this method exhibits good separability and reliability, enabling rapid detection of data anomalies within the power grid, thus laying a solid foundation for the operation and maintenance management of power grid digital operation.

电网数字化运行数据呈现多源异构特征,导致集成效率低,异常检测响应慢。针对这一问题,本文提出了一种基于k -介质聚类的电网数字化运行数据集成方法。基本服务层采用现场可编程门阵列并行架构。这可以实现毫秒级的多源数据同步采集和动态预处理,如机械振动、局部放电信号和温度。在对电网数字化运行结构分析的基础上,提出了实现方案。然后将数据反馈给云服务层,云服务层通过业务集成服务、数据分析和数据访问服务执行数据过滤和分析。随后,数据通过数据库服务器输入到应用层。应用层采用k -介质聚类方法,引入密度加权欧几里得距离度量和自适应质心选择策略,显著提高了多源数据的聚类性能。特别是,所提出的架构支持实时数据处理,并可扩展到跨模式场景,包括与电网监控中的语音到文本系统集成。该方法结合低延迟神经网络原理,有利于在智能运行环境下的及时决策。实验证实了该方法的有效性。它有效地获取和集成了多源异构电网数字化运行数据。不同电网数字化运行数据源的数据吞吐量均超过110 MB/s。综合数据集的廓形系数大于0.91,表明采用该方法对电网数字化运行数据进行整合,具有良好的可分离性和可靠性,能够快速发现电网内部的数据异常,为电网数字化运行的运维管理奠定了坚实的基础。

Prediction of Remaining Life of Aircraft Engines Based on BiLSTM-GRU-Attention Model. 基于BiLSTM-GRU-Attention模型的航空发动机剩余寿命预测
IF 2.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-01 DOI: 10.1177/2167647X251405797

This study aims to enhance the prediction precision of aircraft engine remaining useful life (RUL) by overcoming common challenges in current models, such as ineffective feature extraction and insufficient modeling of long-term temporal dependencies. We propose a novel multilayer hybrid architecture that combines bidirectional long short-term memory (BiLSTM) and gated recurrent unit (GRU) networks, augmented with an attention mechanism to enhance the model's focus on informative temporal patterns. In this framework, raw time series data are initially processed by the BiLSTM to extract bidirectional features associated with engine health conditions. The GRU network is subsequently used to effectively model long-range dependencies, thereby enriching the temporal representation. An adaptive attention module is included to assign varying importance to different features, allowing the model to focus on key indicators of engine condition. Evaluation results on the FD001 and FD003 datasets show that the model achieves root mean squared error reductions ranging from 8.81% to 30.60% and from 7.48% to 37.96%, validating its performance and robustness in RUL forecasting. In comparison with conventional BiLSTM and GRU models, the proposed BiLSTM-GRU-Attention architecture integrates attention-based feature weighting with a hybrid recurrent framework, thereby offering a concise and effective approach to RUL prediction for aircraft engines.

本研究旨在克服现有模型存在的特征提取效率低、对长期时间依赖性建模不足等问题,提高飞机发动机剩余使用寿命(RUL)预测精度。我们提出了一种新的多层混合架构,它结合了双向长短期记忆(BiLSTM)和门控循环单元(GRU)网络,并增加了一个注意机制,以增强模型对信息时间模式的关注。在该框架中,原始时间序列数据首先由BiLSTM处理,以提取与发动机健康状况相关的双向特征。GRU网络随后被用于有效地建模远程依赖关系,从而丰富了时间表征。其中包括一个自适应关注模块,用于为不同特征分配不同的重要性,从而使模型能够专注于发动机状况的关键指标。在FD001和FD003数据集上的评价结果表明,该模型的均方根误差降低幅度分别为8.81% ~ 30.60%和7.48% ~ 37.96%,验证了该模型在RUL预测中的性能和稳健性。与传统的BiLSTM和GRU模型相比,所提出的BiLSTM-GRU- attention架构将基于注意力的特征加权与混合循环框架相结合,从而为飞机发动机RUL预测提供了一种简洁有效的方法。

Monitoring Carbon Emission from Key Industries Based on VF-LSTM Model. 基于VF-LSTM模型的重点行业碳排放监测。
IF 2.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-12-01 Epub Date: 2025-11-18 DOI: 10.1177/2167647X251392796

Human activities that generate greenhouse gas emissions pose a significant threat to urban green and sustainable development. Production activities in key industrial sectors are a primary contributor to high urban carbon emissions. Therefore, effectively reducing carbon emissions in these sectors is crucial for achieving urban carbon peak and neutrality goals. Carbon emission monitoring is a critical approach that aids governmental bodies in understanding changes in industrial carbon emissions, thereby supporting decision-making and carbon reduction efforts. However, current industry-oriented carbon monitoring methods suffer from issues such as low frequency, poor accuracy, and inadequate privacy security. To address these challenges, this article proposes a novel privacy-protected "electricity-carbon'' nexus model, long short-term memory with the vertical federated framework (VF-LSTM), to monitor carbon emissions in key urban industries. The vertical federated framework ensures "usable but invisible" privacy protection for multisource data from various participants. The embedded long short-term memory model accurately captures industry-specific carbon emissions. Using data from key industries (steel, petrochemical, chemical, and nonferrous industries), this article constructs and validates the performance of the proposed industry-level carbon emission monitoring model. The results demonstrate that the model has high accuracy and robustness, effectively monitoring industry carbon emissions while protecting data privacy.

人类活动产生的温室气体排放对城市的绿色和可持续发展构成了重大威胁。关键工业部门的生产活动是造成城市高碳排放的主要因素。因此,有效减少这些行业的碳排放对于实现城市碳峰值和碳中和目标至关重要。碳排放监测是帮助政府机构了解工业碳排放变化的关键方法,从而支持决策和碳减排工作。然而,目前以工业为导向的碳监测方法存在频率低、准确性差、隐私安全性不足等问题。为了应对这些挑战,本文提出了一种新的隐私保护的“电-碳”联系模型,即纵向联合框架的长短期记忆(VF-LSTM),以监测城市关键行业的碳排放。垂直联合框架确保了来自不同参与者的多源数据的“可用但不可见”的隐私保护。嵌入的长短期记忆模型准确地捕获了特定行业的碳排放量。本文利用重点行业(钢铁、石化、化工和有色)的数据,构建并验证了所提出的行业层面碳排放监测模型的性能。结果表明,该模型具有较高的准确性和鲁棒性,能够在保护数据隐私的同时有效监测行业碳排放。

决策科学(DSC)涉及研究复杂的动态系统和过程,以帮助人们在不确定的条件下根据制约因素做出明智的选择。它整合了多学科方法和策略,以评估决策工程流程、确定替代方案并提供见解,从而加强审慎决策。本研究分析了过去 25 年中 DSC 教育和研究趋势的演变趋势和创新。利用书目记录中的元数据,并采用科学绘图法和文本分析法,我们对 DSC 研究的主题、知识和社会结构进行了绘图和评估。研究结果表明,"知识管理"、"决策支持系统"、"数据包络分析"、"模拟 "和 "人工智能"(AI)是 2000-2024 年之前和期间(2000-2024 年)DSC 解决问题所需的一些重要技能和知识。然而,在最近的数字化转型浪潮中,这些技术正在发生重大演变,数据分析框架(包括大数据分析、机器学习、商业智能、数据挖掘和信息可视化等技术)变得至关重要。DSC 教育和研究继续反映实践中的发展,通过虚拟/在线学习开展可持续教育的情况日益突出。创新的教学方法/策略还包括计算机模拟和游戏("边玩边学 "或 "角色扮演")。当今时代,人工智能以对话式聊天机器人(Chatbot agent)和生成式人工智能(GenAI)等不同形式被广泛采用,如在教学、学习和学术活动中使用的聊天生成式预训练转换器,它面临着各种挑战(学术诚信、剽窃、侵犯知识产权以及其他伦理和法律问题)。未来的 DSC 教育必须创新性地将 GenAI 融入 DSC 教育,并应对由此带来的挑战。

The Impact of Cloaking Digital Footprints on User Privacy and Personalization. 隐藏数字足迹对用户隐私和个性化的影响。

Our online lives generate a wealth of behavioral records-digital footprints-which are stored and leveraged by technology platforms. These data can be used to create value for users by personalizing services. At the same time, however, it also poses a threat to people's privacy by offering a highly intimate window into their private traits (e.g., their personality, political ideology, sexual orientation). We explore the concept of cloaking: allowing users to hide parts of their digital footprints from predictive algorithms, to prevent unwanted inferences. This article addresses two open questions: (i) can cloaking be effective in the longer term, as users continue to generate new digital footprints? And (ii) what is the potential impact of cloaking on the accuracy of desirable inferences? We introduce a novel strategy focused on cloaking "metafeatures" and compare its efficacy against just cloaking the raw footprints. The main findings are (i) while cloaking effectiveness does indeed diminish over time, using metafeatures slows the degradation; (ii) there is a tradeoff between privacy and personalization: cloaking undesired inferences also can inhibit desirable inferences. Furthermore, the metafeature strategy-which yields more stable cloaking-also incurs a larger reduction in desirable inferences.

我们的网络生活产生了大量的行为记录——数字足迹——这些记录被技术平台存储和利用。这些数据可以通过个性化服务为用户创造价值。然而,与此同时,它也对人们的隐私构成了威胁,因为它提供了一个非常亲密的窗口,可以看到他们的私人特征(例如,他们的个性、政治意识形态、性取向)。我们探索了隐形的概念:允许用户隐藏他们的部分数字足迹,以防止不必要的推断。本文解决了两个悬而未决的问题:(i)随着用户不断产生新的数字足迹,隐身在长期内是否有效?(ii)隐藏对理想推论的准确性有什么潜在影响?我们介绍了一种专注于掩盖“元特征”的新策略,并将其与仅仅掩盖原始足迹的效果进行了比较。主要发现是:(1)虽然隐形效果确实会随着时间的推移而减弱,但使用元特征可以减缓这种退化;(ii)隐私和个性化之间存在权衡:掩盖不希望的推断也会抑制希望的推断。此外,元特征策略——产生更稳定的隐形——也会导致理想推断的更大减少。

Maximizing Influence in Social Networks Using Combined Local Features and Deep Learning-Based Node Embedding. 利用组合本地特征和基于深度学习的节点嵌入,最大化社交网络中的影响力。

The influence maximization problem has several issues, including low infection rates and high time complexity. Many proposed methods are not suitable for large-scale networks due to their time complexity or free parameter usage. To address these challenges, this article proposes a local heuristic called Embedding Technique for Influence Maximization (ETIM) that uses shell decomposition, graph embedding, and reduction, as well as combined local structural features. The algorithm selects candidate nodes based on their connections among network shells and topological features, reducing the search space and computational overhead. It uses a deep learning-based node embedding technique to create a multidimensional vector of candidate nodes and calculates the dependency on spreading for each node based on local topological features. Finally, influential nodes are identified using the results of the previous phases and newly defined local features. The proposed algorithm is evaluated using the independent cascade model, showing its competitiveness and ability to achieve the best performance in terms of solution quality. Compared with the collective influence global algorithm, ETIM is significantly faster and improves the infection rate by an average of 12%.

影响最大化问题有几个问题,包括低感染率和高时间复杂性。由于时间复杂性或自由参数的使用,许多建议的方法都不适合大规模网络。为了应对这些挑战,本文提出了一种名为 "影响力最大化嵌入技术"(ETIM)的局部启发式算法,该算法使用壳分解、图嵌入和还原,并结合了局部结构特征。该算法根据网络壳之间的连接和拓扑特征选择候选节点,从而减少了搜索空间和计算开销。它使用基于深度学习的节点嵌入技术创建候选节点的多维向量,并根据本地拓扑特征计算每个节点对传播的依赖性。最后,利用前一阶段的结果和新定义的本地特征识别出有影响力的节点。利用独立级联模型对所提出的算法进行了评估,结果表明该算法具有竞争力,能够在解决方案质量方面达到最佳性能。与集体影响全局算法相比,ETIM 的速度明显更快,感染率平均提高了 12%。

DMHANT: DropMessage Hypergraph Attention Network for Information Propagation Prediction. DMHANT:用于信息传播预测的 DropMessage 超图注意力网络。
IF 2.6 4区 计算机科学 Q2 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2025-10-01 Epub Date: 2024-10-23 DOI: 10.1089/big.2023.0131

Predicting propagation cascades is crucial for understanding information propagation in social networks. Existing methods always focus on structure or order of infected users in a single cascade sequence, ignoring the global dependencies of cascades and users, which is insufficient to characterize their dynamic interaction preferences. Moreover, existing methods are poor at addressing the problem of model robustness. To address these issues, we propose a predication model named DropMessage Hypergraph Attention Networks, which constructs a hypergraph based on the cascade sequence. Specifically, to dynamically obtain user preferences, we divide the diffusion hypergraph into multiple subgraphs according to the time stamps, develop hypergraph attention networks to explicitly learn complete interactions, and adopt a gated fusion strategy to connect them for user cascade prediction. In addition, a new drop immediately method DropMessage is added to increase the robustness of the model. Experimental results on three real-world datasets indicate that proposed model significantly outperforms the most advanced information propagation prediction model in both MAP@k and Hits@K metrics, and the experiment also proves that the model achieves more significant prediction performance than the existing model under data perturbation.

预测传播级联对于理解社交网络中的信息传播至关重要。现有方法总是关注单个级联序列中受感染用户的结构或顺序,忽略了级联和用户之间的全局依赖关系,不足以描述他们的动态互动偏好。此外,现有方法在解决模型稳健性问题方面也存在不足。为了解决这些问题,我们提出了一种名为 "DropMessage 超图注意力网络 "的预测模型,该模型基于级联序列构建超图。具体来说,为了动态获取用户偏好,我们根据时间戳将扩散超图划分为多个子图,开发超图注意力网络来显式学习完整的交互,并采用门控融合策略将它们连接起来进行用户级联预测。此外,为了提高模型的鲁棒性,还增加了一种新的立即删除方法 DropMessage。在三个真实数据集上的实验结果表明,所提出的模型在 MAP@k 和 Hits@K 两个指标上都明显优于最先进的信息传播预测模型,实验还证明该模型在数据扰动下比现有模型取得了更显著的预测性能。
