<正>如果说上一期专栏我们是得意了一把,侧重分享了Html5页面搭建的可视化新闻策划在社会化传播的优势的话,这一次我们将聊聊现有的可视化新闻产品值得反思的地方。从网易新媒体实验室的操作案例来说,保证用户体验是判断一个可视化新闻成功与否的重要标准,而实现这个标准的关键,是不能徒增用户阅读成本。我们观测了最近制作的30个可视化新闻选题,从PV数、UV数、用户停留时间、用户回流等量化数据进行比较,同时进行了一组20人的用户深度访谈,以进一步分析用户对现有可视化新闻产品的认知和使用偏好,以及挖掘用户对这类新闻策划使 相似文献

News mentions to academic papers has provided an important channel for research to yield impact on broad audience in the society, and is particularly useful in scholarly communication, scientific outreach and altmetrics. Unlike academic paper, news articles are often influenced by social factors such as culture, ideology and geography. It is therefore uncertain whether news mentions to academic paper is valid for evaluative purpose as expected by altmetrics studies. In response, this study has conducted large scale statistical analysis to explore country's preference over news mentions, based on the assumption that if news mentions to academic paper is not (or weakly) influenced by social factors, no obvious country's preference would be observed, and the vice versa. The major findings are: (1) From the macro perspective, overall distribution of news mentions is highly imbalanced, with several developed countries taking the dominant position. However, no obvious preference towards domestic papers was observed. (2) From the micro perspective, based on the ZINB test results, news from all countries have more positively mentioned domestic papers and simultaneously shown preference over papers from certain countries. (3) In terms of disciplinary comparison, disciplinary differences were observed in the impact strength and specific preference. These results suggest that in micro level country's preference exist for news mentions to academic papers, but in macro level, country's preference is insignificant. Therefore, it is suggested that news mentions can be used for assessing purpose in the macro level. 相似文献

个性化关键技术研究综述 总被引：1，自引：0，他引：1
个性化研究的关键技术主要包括有三个方面的内容:用户建模、推荐系统和评价。首先,用户建模是收集用户数据,目的是为推荐系统提供用户的兴趣、偏好等建立模型;其次,推荐系统的作用是根据用户模型为用户推荐个性化内容,是个性化的核心内容;最后,评价系统根据用户对个性化应用的满意程度,反馈给推荐系统调整建模策略。个性化应用是一个不断反馈修正的过程。 相似文献

This study aims at understanding international news differences by studying the headlines of over 360,000 news stories posted on the Twitter pages of 12 Arabic and English news organizations. The most referenced countries as well as figures and political actors are examined in these headlines, and the results show that a number of news values elements provide insight into the nature of the news selection. While Arabic channels are mostly focused on the events taking place in the Middle East (proximity), some English-language channels show clear preference for the countries from which they are located, especially CNN and Sky News, as well as Arabic and English state-owned media outlets like France 24 and RT (agenda and ideology). The findings suggest that news content largely follows a number of news values criteria that can explain the news selection process. 相似文献

Exemplification (the use of examples) in news stories is a common method of providing information about social phenomena to make stories more interesting to audience members. However, previous research has consistently linked exemplification to highly inaccurate perceptions about the prevalence or severity of a given phenomena. The current study further explored outcomes of exemplification by examining the extent to which the practice influenced perceptions of news credibility. Exemplification of public opinion via layperson quotes was found to differentially affect perceptions of news story credibility. Anecdotal exemplification, however, did not predict credibility ratings. Implications for journalism and democratic participation as well as partisans' preference for congenial coverage in news stories are discussed. 相似文献

This article presents a secondary analysis of two multi-national cross-sectional surveys conducted in 2015 (11 countries, N?=?10,570) and 2017 (4 countries, N?=?2165) to examine the relationship between populist attitudes and media use. The results indicate that populist citizens are more likely to consume news than non-populist citizens. Specifically, populist citizens exhibit a preference for commercial television (TV) news, as well as a tendency to read tabloid newspapers. While they use fewer quality newspapers, public TV news are not systematically avoided. Regarding the online news environment, populist citizens prefer Facebook over Twitter as a source of political information. This selective pattern will be discussed in light of the debates on news audience polarization and political polarization. 相似文献

ABSTRACT The online environment has radically changed the way in which users consume, discover and manipulate news. The growing relevance of social media platforms and digital intermediaries for news sharing and consumption increase the likelihood of citizens to be exposed to online news even when they are not seeking it. This digital transformation fundamentally challenges the way online news use and exposure have been conceptualized and measured, affecting also to citizens’ knowledge about public affairs and politics. This article examines the factors that predict the probability to be an “incidentally exposed news user” online. Specifically, based on a representative US sample from the Pew Research Centre, this study analyses the role of media preference, use and trust. Findings indicate that beyond users’ demographics and loyalty, readers’ news preferences, uses and trust, specially of social media platforms, affect their probability to be incidentally exposed to news online. These results have important empirical and theoretical implications for understanding the connection between readers’ news consumption patterns and online exposure, intentional or incidental. 相似文献

For Latinos in the United States, decisions reflecting which language they prefer for news media consumption can have substantial effects on the quality of the content they receive. However, little is known about what influences Latinos’ language preferences for news media consumption. This project looks to fill that void to the immediate appeal of academics and media analysts by asking, What influences Latinos’ language preference for news? This project builds on social psychology theories highlighting the role played by social identity and self-categorization for inspiring culturally consistent behaviors. This social identity approach focuses on the embrace of Latino characteristics and the complementary nature of Spanish-language media outputs relative to those characteristics. Using the 2006 Latino National Survey, the role of identity is explored. The results indicate that language preferences for news consumption are indeed related to various social identity measures among Latinos in the United States. 相似文献
