Understanding the majority opinion formation process in online environments: An exploratory approach to Facebook     

Sangwon Lee  Taehyun Ha  Daeho Lee  Jang Hyun Kim 《Information processing & management》2018,54(6):1115-1128

Majority opinions are often observed in the process of social interaction in online communities, but few studies have addressed this issue with empirical data. To identify an appropriate theoretical lens for explaining majority opinions in online environments, this study investigates the skewness statistic, which indicates how many “Likes” are skewed to major comments on a Facebook post; 3489 posts are gathered from the New York Times Facebook page for 100 days. Results show that time is not an influential factor for skewness increase, but the number of comments has a logarithmic relation to skewness increase. Regression models and Chow tests show that this relationship differs depending on topic contents, but majority opinions are significant in overall. These results suggest that the bandwagon effect due to social affordance can be a suitable mechanism for explaining majority opinion formation in an online environment and that majority opinions in online communities can be misperceived due to overestimation.  相似文献   

欧洲九国共产党情报局机关刊物《争取持久和平,争取人民民主!》与中国关系考述(1949-1956)     

哈战荣 《图书馆杂志》2020,(4):21-26

《争取持久和平,争取人民民主!》是20世纪40年代中后期,欧洲九个社会主义国家的共产党和工人党为了一致行动而建立的情报局机关刊物。该刊物对新中国初期我国经济社会建设及成就进行了大量宣传与报道,对加强我国与世界其他爱好和平、渴求民主的各国人民加强互信、长存友谊贡献很大,也对当前学者研究新中国初期我国经济社会发展的过程、成就和经验等提供了原始史料,学术研究意义也很重大。但是,目前对这份刊物及其发挥过的重大作用了解的人少之又少,时值中国共产党成立100周年之际,对其创刊与发行的历史过程进行回顾、宣传中国社会经济发展的全貌进行展示、推动世界社会主义运动的作用进行肯定,意义都很重大。  相似文献

Using Natural Language Processing to Predict Item Response Times and Improve Test Construction     

Peter Baldwin  Victoria Yaneva  Janet Mee  Brian E. Clauser  Le An Ha 《Journal of Educational Measurement》2021,58(1):4-30

In this article, it is shown how item text can be represented by (a) 113 features quantifying the text's linguistic characteristics, (b) 16 measures of the extent to which an information‐retrieval‐based automatic question‐answering system finds an item challenging, and (c) through dense word representations (word embeddings). Using a random forests algorithm, these data then are used to train a prediction model for item response times and predicted response times then are used to assemble test forms. Using empirical data from the United States Medical Licensing Examination, we show that timing demands are more consistent across these specially assembled forms than across forms comprising randomly‐selected items. Because an exam's timing conditions affect examinee performance, this result has implications for exam fairness whenever examinees are compared with each other or against a common standard.  相似文献
