News Sites

SUMMARY

People worldwide rely on the news media to report current events accurately and without bias. TV and radio have been available for decades to report the news, but the Internet is rapidly becoming a major source for instantaneous news. During and following the events of September 11, users with access to the Internet watched the terrorist attacks of September unfold and have continued to watch and monitor the “War on Terrorism” via the Internet. This column presents a highly select list of Web sites that generate current news information; news about September 11 and the War on Terrorism is featured.     

Participatory journalism – the (r)evolution that wasn't. Content and user behavior in Sweden 2007–2013

A contemporary debate in media studies concerns participation and empowerment, and to what extent digital media shift power to the citizens. This study assesses the long‐term viability of participatory journalism using Swedish content and user data. Inclusion of comments and blog‐links on news sites increased from 2007 to 2010, and decreased rather dramatically from 2011 onward. Posting user comments or writing blogs have never been activities that have appealed to a majority of the Swedes. Participatory journalism seems to have decreasing value to producers and little appeal to users. A shift in how power is distributed in the public sphere is absent. This is not primarily a problem of reluctant producers but, more importantly, a lack of interest from users.     

Interactive Visualization of News Distribution in Blog Space

This paper proposes a visualization method of news distribution in Blog space. Recently, Blog is becoming one of the important information resources on the Web, from which trend information can be obtained. On the other hand, online news site is another information resource, which reports latest events in the world. This paper focuses on the combination of both resources, and proposes a method for visualizing news distribution in Blog space, which indicates various access patterns to news articles in Blog space. The types of objects that are to be visualized as well as their relationships are defined, based on which interactive information visualization system is proposed. Experiments with test subjects are performed to investigate the viewpoints they employ for examining news distribution in Blog space. The results show that test subjects can examine news distribution in Blog space from various viewpoints, which affects their estimation of the impacts of news articles.

Driving a Wedge Between Evidence and Beliefs: How Online Ideological News Exposure Promotes Political Misperceptions

This article has 2 goals: to provide additional evidence that exposure to ideological online news media contributes to political misperceptions, and to test 3 forms this media‐effect might take. Analyses are based on representative survey data collected during the 2012 U.S. presidential election (N = 1,004). Panel data offer persuasive evidence that biased news site use promotes inaccurate beliefs, while cross‐sectional data provide insight into the nature of these effects. There is no evidence that exposure to ideological media reduces awareness of politically unfavorable evidence, though in some circumstances biased media do promote misunderstandings of it. The strongest and most consistent influence of ideological media exposure is to encourage inaccurate beliefs regardless of what consumers know of the evidence.

Digital News Consumption and Copyright Intervention: Evidence from Spain Before and After the 2015 “Link Tax”

We analyze patterns of digital news consumption before and after a “link tax” was introduced in Spain. This new legislation imposed a copyright fee for showing snippets of content created by newspapers and resulted in the shutdown of Google News Spain. The Spanish copyright law is a precedent to the Copyright Directive currently submitted to the European Parliament, which is planning to impose a similar “link tax.” We offer empirical evidence that can help evaluate the impact of that sort of intervention. We analyze data tracking news consumption behavior to assess changes in audience reach and audience fragmentation. We show that the law has no discernible impact on reach, but we identify an increase in the fragmentation of news consumption.     

Attention to news and its dissemination on Twitter: A survey

In recent years, news media have been hugely disrupted by news promotion, commentary and sharing in online, social media (e.g., Twitter, Facebook, and Reddit). This disruption has been the subject of a significant literature that has largely used AI techniques – machine learning, text analytics and network models – to both (i) understand the factors underlying audience attention and news dissemination on social media (e.g., effects of popularity, type of day) and (ii) provide new tools/guidelines for journalists to better disseminate their news via these social media. This paper provides an integrative review of the literature on the professional reporting of news on Twitter; focusing on how journalists and news outlets use Twitter as a platform to disseminate news, and on the factors that impact readers’ attention and engagement with that news on Twitter. Using the precise definition of a news-tweet (i.e., divided into user, content and context features), the survey structures the literature to reveal the main findings on features affecting audience attention to news and its dissemination on Twitter. From this analysis, it then considers the most effective guidelines for digital journalists to better disseminate news in the future.

In Face on Facebook: Brooklyn's Drag Community and Sociotechnical Practices of Online Communication

Recently, Brooklyn has seen an explosion of drag culture, with dozens of performers taking the stage in any given week. Social media plays a vital role for members of this community, simultaneously allowing self‐promotion and community solidarity. Drawing on focus group interviews, we analyze the communication practices of Brooklyn's drag performers, examining both the advantages and drawbacks of social media platforms. Using conceptual frameworks of faceted identity and relational labor, our discussion focuses on affordances and constraints of multifaceted identity in online contexts and theories of seamful design. We contend that by analyzing online communication practices of drag performers, it becomes possible to identify gaps between embedded ideologies of mainstream social media technologies and the localized values of outsider communities.

基于规则分析的新闻视频口播帧检测

新闻视频的主体内容是一系列的新闻单元,准确地对新闻单元进行分割是新闻视频自动索引的重要依据,同时也是对新闻视频进行基于内容的视频分析的过程中所要解决的一个基本问题。由于新闻主持人口播镜头的开始通常是一个新闻单元的开始,所以检测新闻主持人口播帧是定位和分割新闻单元的有效途径。论文提出的基于规则分析的口播帧检测方法(DBRA,DetectionBasedonRuleAnalysis)是一种全新的口播帧检测方法,该方法通过分析新闻视频口播帧具有的一些规则(亦可称其为特点),由计算机系统完全独立地对新闻视频进行分析、并自动检测出口播帧。该检测方法与现有的检测方法相比,不仅使用较为方便,而且具有一定的智能性。     

Extent of private information disclosure on online social networks: An exploration of Facebook mobile phone users

The present study adopts the Communication Privacy Management theory and investigates the factors that influence the extent of private information disclosure of Facebook mobile phone users. Using a sample size of 488 adult mobile phone users, the study further investigates the differential impact of age on the extent of private information disclosure. Results from the logistic regressions run reveal that use of smartphones to access social networking sites, use of multiple social networks, and being female decrease the likelihood of private information disclosure. In addition, usability problems increase the likelihood of information disclosure by older adults. The analyses show no association between perceived benefit and private information disclosure.     

Strategic self-presentation on Facebook: Personal motives and audience response to online behavior

People have always been concerned with their social image and engaged in strategic self-presentation (Goffman, 1959), but the growth of social networking sites (SNS) has had a major influence on such social endeavors. When people choose how to present themselves online, they use strategies and make choices that influence the liking and respect they receive from others. We examine a model that links: (a) motives for self-presentation, (b) actual online behavior on Facebook, and (c) feedback: social network members' responses (“likes,” comments). One hundred and fifty-six undergraduates (37 males, 119 females, mean age = 24.5) reported on their last three Facebook status updates (468 status updates overall). Based on structural equation modeling, we found that performance goals predict increased levels of self-enhancement on Facebook and increased levels of social feedback – “likes” and comments by others. Mastery goals do not predict increased levels of self-derogation (posting negative contents about self), but those who do choose to derogate also receive increased numbers of “likes” and comments from their network friends.     

基于Web Service架构的新闻服务研究

Posting,commenting, and tagging: Effects of sharing news stories on Facebook

Social networking sites such as Facebook provide new ways of sharing news stories that allow users to act as opinion leaders in their networks, encourage discussion, and potentially increase their involvement in current events. This study identifies the particular features of Facebook that facilitate the discussion of news and tests their effects on involvement and feelings of influence. Participants (N = 265) in a 3 (Broadcast level: news feed vs. wall post vs. direct message) × 3 (Elaboration: opinion vs. question vs. no comment) × 2 (Involving-friends: tag vs. no tag) between-subjects factorial experiment were randomly assigned to share a story from a news website on Facebook. Results show that user involvement in the news content depends on the social affordances of the site, particularly those that allow for audience customization and those that drive network feedback. Asking the network’s opinions and targeting specific friends led to greater involvement in the news content. Discussion through comments led to a greater sense of influence and greater involvement for those sharing the news story. These findings highlight the importance of encouraging individuals to act as sources of information in their networks to drive engagement in current events in the changing news landscape.
