From “Selfies” to Breaking Tweets

The aim of this paper is to analyse the different ways in which journalists negotiate representations of their professional and personal identity on social media platforms. We argue that the differing representations of personal and professional identity on social media correspond to the professional, organisational and institutional tensions that have emerged in this new space. Using qualitative interviews with various journalists and editorial staff from Australian media organisations across television, radio, print and online publications, we indicate that journalists present their personal and professional identity on social media in three different ways. The first group create public, professional social media accounts, but also create secondary, private accounts that are only accessible to personal networks. The second group either choose, or are required by their media organisation, to only have a professional presence on social media; that is, they have public accounts that are only associated with their media organisation and display only their professional activities. The last group merge a professional and personal identity on their social media sites, showing aspects of their personal and their professional lives on publically available accounts.     

Journalists’ Coverage of Online Firestorms in German-Language News Media

When people perceive events that conflict with their expectations they can easily express their agitation and concerns online and likely find others who share their opinion. When large quantities of messages containing negative word-of-mouth suddenly spread in social media we speak of an online firestorm. By covering the outcry, journalists elevate it onto a mainstream communication platform and support the process of scandalization. Content analysis was used to explore how journalists, working for German-language media, cover this phenomenon. Over a period of 16 months, 130 online firestorms were identified and analyzed. Based on a typology of online firestorms, we have found that the majority of cases address events of perceived discrimination and moral misconduct aiming at societal change. Vilification of the organization or person occurred to a much lesser extent. Thus, journalistic coverage of the phenomenon focuses on the rectification attempts of an aroused public. Image-repair responses of the firestorm objects are quoted by journalists in about half of the articles, thereby providing some balanced reporting about the online criticism. This study provides an initial insight into how online firestorms are used as a topic of news coverage by journalists and explores journalists’ contribution to attempts of online scandalization.     

Investigative Reporting in the Networked Media Environment

The internet and social media sites are used extensively by violent extremist actors, providing new areas of inquiry for journalists reporting violent extremism. Based on 26 in-depth interviews with Norwegian media professionals, the present article describes how journalists monitor, assess, and make use of online information in investigative reporting of violent extremist groups in today’s networked media environment, characterized by complex interaction patterns, a plurality of voices, and blurred boundaries between private and public communication. While existing research on journalists’ use of social media as a source has tended to emphasize breaking news, the present article focuses on longer-term investigative efforts of journalists. The article gives insights into journalistic investigative practices in the networked media environment, in general, and in reporting violent extremism, in particular.

融合统计学习和语义过滤的ADR信号抽取模型构建研究

[目的/意义]社交媒体的出现为医疗健康数据的收集提供了新的途径,应用自然语言处理技术从社交媒体中抽取患者报告的ADR（Adverse Drug Reaction,药物不良反应）信号对于改善药物不良反应监测的临床和科学知识具有很大的潜力。然而,从社会媒体中提取患者报告的ADR信号仍然面临重大挑战。为此,开发一个利用高级自然语言处理技术从健康主题社交媒体中抽取ADR信号的研究模型。[方法/过程]该模型首先采用基于多词典源匹配的方法,从嘈杂的社交媒体中识别医学实体;然后采用最短依存路径核函数为基础的统计学习方法提取药物不良事件;并利用药品安全数据库的语义知识过滤药物的治疗和适用症信息以及否定的药物不良事件;最后,对报告源进行分类剔除传闻等噪音信息。[结果/结论]通过收集糖尿病论坛上的数据对模型的有效性进行验证,结果显示该模型的每一部分都有助于其整体性能的提升。

Testing a cultural orientation model of electronic word-of-mouth communication: a comparative study of U.S. and Korean social media users

Expanding electronic word-of-mouth (eWOM) literature and cross-cultural literature, this study proposes a horizontal–vertical dimensions of individualism and collectivism (HVIC)-eWOM model in a cross-cultural context. We employed HVIC at the individual level to explain the variance of eWOM communications on social media. We collected data from American and Korean social media users to examine how the hypothesized model fits the samples from each country. The analysis of the HVIC-eWOM model within and between the two countries revealed that there are some similarities and differences in influential cultural dimensions on eWOM communications in the two countries. The results suggest that vertical aspects of individualism and collectivism are significant drivers of opinion-leadership and opinion-seeking tendencies for both countries.     

Personality structure of brands on social networking sites and its effects on brand affect and trust: evidence of brand anthropomorphization

The current study explored the personality dimensions of brands on Social Networking Sites (SNSs) using a South Korean sample. Through a series of exploratory and confirmatory factor analyses, six dimensions (i.e. Openness, Conscientiousness, Agreeableness, Extraversion, Warmth, and Contentiousness) were yielded for brands with SNS presence. The data also produced six dimensions (i.e. Openness, Sincerity, Extraversion, Competence, Agreeableness, and Ruggedness) for brands without SNS presence. The results show that brands with which consumers interact on SNSs have more human-like personalities than brands absent from SNSs, and the personality dimensions affected brand affect and trust to varying degrees.
