User-aware multilingual abusive content detection in social media     

《Information processing & management》2023,60(5):103450

Despite growing efforts to halt distasteful content on social media, multilingualism has added a new dimension to this problem. The scarcity of resources makes the challenge even greater when it comes to low-resource languages. This work focuses on providing a novel method for abusive content detection in multiple low-resource Indic languages. Our observation indicates that a post’s tendency to attract abusive comments, as well as features such as user history and social context, significantly aid in the detection of abusive content. The proposed method first learns social and text context features in two separate modules. The integrated representation from these modules is learned and used for the final prediction. To evaluate the performance of our method against different classical and state-of-the-art methods, we have performed extensive experiments on SCIDN and MACI datasets consisting of 1.5M and 665K multilingual comments, respectively. Our proposed method outperforms state-of-the-art baseline methods with an average increase of 4.08% and 9.52% in the F1-score on SCIDN and MACI datasets, respectively.  相似文献   

Coping with cultural differences in healthcare: Chinese immigrant mothers’ health information sharing via WeChat     

《Int J Intercult Relat》2021

Immigrants face the challenge of obtaining culturally specific health information and adapting to a new healthcare system. Through qualitative content analysis, this study explores how Chinese immigrant mothers use the ethnic social media—WeChat to engage in health information sharing and coping with cultural differences in healthcare between the U.S. and China. Based on the data collected from one WeChat group in a metropolitan city in the northeastern U.S., Chinese immigrant mothers frequently discuss the topics of “doctors and hospitals,” “insurance and cost,” “medicine and treatment,” and “alternative health care.” They constantly compare Chinese health care beliefs and practices with western ones. They adopt various acculturation strategies to manage the cultural differences in healthcare beliefs, practices, and systems. We call for future research to further examine immigrants’ health information sharing via social media and consider acculturation as coping strategies or processes in the health communication context.  相似文献

媒介竞争、选举竞争和公共产品供给   总被引：1，自引：0，他引：1  

刘成奎 《中国软科学》2010,(5)

不同阶层或地区之间的公共产品供给经常不均衡,媒介竞争与媒介捕获导致的各阶层、各地区之间信息分布的不均衡是重要根源.媒介声望竞争有助于媒介提供广泛与差异化的信息,而媒介经济利益竞争会引致媒介信息偏好高收入群体,特别是容易诱发媒介捕获,由此会导致媒介信息偏好特定利益人.媒介信息的失真导致政府官员偏好高可见度公共产品的供给,从而引致政府的公共产品决策偏向于高收入群体或特定利益人.大力发展媒介产业、建立媒介自律与重视声望机制、重视对官员任用的声望考评、保留或建立公益性媒介机构是扭转公共产品供给失衡的有效对策.  相似文献

合成生物学通过引入工程科学“自下而上”认识生命体系的理念,在生命科学研究中采用“设计—构建—测试—学习”迭代的研究范式,并在基因组和系统生物学的基础上,构建工程化的新生命体系,为生命科学提供了“从创造到理解”的新途径,不仅颠覆了从整体到局部的“格物致知—还原论”的传统研究策略,还开启了理解生命本质的“建物致知”新文化。同时,合成生物学将生物技术由“模拟自然过程”和“遗传工程改造”上升至“定量理性设计”和“标准化构建测试”的高度,推动生物工程和代谢工程朝着对标生命过程的高效率、普适性的工程化“重编程”,甚至是“从头构建”的新高度,以实现“建物致用”的目标。文章梳理了合成生物学近年来在生命科学基础研究中“建物致知”方面的重要进展,列举了其在化工、医药、食品、环境等应用领域中“建物致用”的具体案例,展现了合成生物学对人类社会全面发展正在发挥的重大影响,强调了为确保合成生物学的健康、快速发展,构建会聚生态系统与治理体系的重要性。  相似文献

Social commerce research: Definition,research themes and the trends     

《International Journal of Information Management》2017,37(3):190-201

Social commerce, an emerging phenomenon rooted in social media and Web 2.0 technologies, has attracted the attention of many researchers. The number of publications on social commerce has grown exponentially in the past 10 years. Now, social commerce has become a significant emerging research area. In this paper, we first define the boundary of social commerce research and then attempt to review the extant literature in this area comprehensively and systematically. Based on the definition, this study surveyed 1369 peer-reviewed academic publications in the social media, Web 2.0, and other related areas. Following the survey, 418 of the publications were identified as social commerce research. Then, latent semantic analysis (LSA), a text mining approach, was applied to summarize the current state of social commerce research. LSA results show that there are three major research themes in the current social commerce research: organization, advertisement, and word-of-mouth. Each theme discusses topics such as innovation, user-generated content, and reputation, among others. In addition, we identify some interesting trends. The first main trend is that innovation, corporate reputation, and user-generated content remain the major research topics, although they are experiencing a slight decline. The second main trend is that online reviews, trust, and e-word-of-mouth are attracting more attention from researchers.  相似文献   

News media,social media,and hyperlink networks: An examination of integrated media effects     

Jiawei Sophia Fu  Michelle Shumate 《The Information Society》2017,33(2):53-63

Research typically focuses on one medium. But in today's digital media environment, people use and are influenced by their experience with multiple systems. Building on media ecology research, we introduce the notion of integrated media effects. We draw on resource dependence and homophily theories to analyze the mechanisms that connect media systems. To test the integrated media effects, we examine the relationships between news media visibility and social media visibility and hyperlinking patterns among 410 nongovernmental organization (NGO) websites in China. NGOs with greater news media visibility and more social media followers receive significantly more hyperlinks. Further, NGOs with a similar number of social media followers prefer to hyperlink to each other. The results suggest that both news media and social media systems are related to the configuration of hyperlink networks, providing support for the integrated media effects described. Implications for the study of hyperlink networks, online behaviors of organizations, and public relations are drawn from the results.  相似文献
