Using a unique dataset of question-and-answer (Q&amp;A) interactions from China’s major e-interaction platforms, established by the stock exchanges, our study provides insights into regulated firm-investor communications in a structured Q&amp;A setting. Unlike informal social media channels, these platforms enable official responses from firm representatives, typically board secretaries, under direct regulatory oversight. By analyzing rumor-related Q&amp;A pairs with regression models and several robustness checks, we find that firms can benefit from strategic response messaging. Our results show that prompt responses from management have a positive effect on the stock market. Interestingly, responses that closely match the questions do not necessarily lead to improved ARs. Responses that convey more positive emotions are associated with higher subsequent gains in ARs. Further, we investigate the role of specific conditions, including prior stock performance, investor sentiment in questions, and question topics, in the relationship between response behavior and investor reaction. These findings offer new insights into the consequences of management responses to unconfirmed events and highlight the potential value of Q&amp;A communication between firm managers and potential investors.</div></div>","PeriodicalId":50365,"journal":{"name":"Information Processing & Management","volume":"62 5","pages":"Article 104162"},"PeriodicalIF":7.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although existing studies have attempted to integrate multimodal data for this task, they often struggle to effectively model cross-modal correlations. Most approaches focus on the global features of each modality and compute scalar similarities, which limits their capacity to learn and process comprehensive samples. To address this challenge, this paper introduces a novel cross-modal content correlation network. This method leverages salient objects from images and nouns from the text as the multimodal content, utilizing CLIP to extract generalizable features for similarity measurement, thereby enhancing cross-modal interaction. By applying convolution to the similarity matrix between nouns and image crops, the model captures learnable patterns of cross-modal content correlations that facilitate news classification, without relying on predefined scalar similarities or requiring supplementary information or auxiliary tasks. Experiments on two real-world datasets reveal that our method outperforms previous methods, achieving 3.1% and 1.9% gains in overall accuracy on Weibo and Twitter, respectively.

Previous studies in this area have examined various features of retracted papers. Based on these findings, the aim of this paper is to construct a model to predict potential retraction cases, and analyze the retraction features over time and across fields. Specifically, we construct an XGBoost model using 9424 normal and retracted biomedical papers published between the year 1983 and the year 2023 from the Web of Science Core Collection database. This model has an accuracy of 87 %. Nine important features are identified, ranked, and their contributions to the model are discussed using interpretable machine learning techniques. Moreover, heterogeneity analysis by publication year reveals that the importance of these features has changed over time. The generalizability of the model is validated in the field of computer science (98.12 %) and telecommunication (74.92 %). Finally, we analyze the similarities/differences in these features among the three fields. The result of this study confirms the features identified by previous studies. Further, the way that these features describe and predict whether a paper is retracted or not is revealed by interpretable machine learning techniques. This has not been discussed much in previous studies. Additionally, this study provides details on how these features change over time and across disciplines in predicting retractions.

Additionally, the study delves into the intricate interplay among these variables. Analysis of data collected from 866 young people demonstrates that cyberbullying perpetration and communication overload are important factors contributing to depressive mood and mobile app fatigue.

However, existing multi-domain detection methods exhibit two primary limitations: dependence on precise domain annotation and inherent bias arising from single-domain categorization. To address these challenges, this paper introduces the Domain-Specific Narrow-Coverage Tree-Based Taxonomy (<span><math><msup><mrow><mtext>DNT</mtext></mrow><mrow><mn>2</mn></mrow></msup></math></span>), which enables more precise domain classification and domain relationship elucidation through refined categories. The constructed dataset is annotated with multiple labels by Large Language Models (LLMs), mitigating reliance on manual efforts and reducing annotation costs while maintaining annotation quality. Furthermore, a Hierarchical Fine-Grained Domain (HFGD) Fake News Detection Method is proposed, which explicitly employs a heterogeneous network to model multi-relationships. This method can mitigate domain bias and comprehensively capture news diversity and domain interactions. Specifically, domain cohesion based on news semantics is designed to reflect the relevance of news within a domain. News items are integrated as intersection nodes into the tree structure of multilevel domains to construct the heterogeneous network. Graph representation learning then fuses directly or indirectly connected news and domain information during feature enhancement. Finally, a composite loss is designed for news and domain node classification. HFGD captures potential differences and commonalities in domains and enhances label adaptation through domain interactions. Experiments on our dataset demonstrate that HFGD outperforms state-of-the-art methods by 1.08% and 0.91% in overall accuracy and macro-F1 score, respectively. Specifically, in the education and military domains with limited sample sizes, HFGD achieves 5.74% and 4.1% improvements in macro-F1 score over the second-best method.
