Locations, e.g., countries, states, cities, and point-of-interests, are central to news, emergency events, and people's daily lives. Automatic identification of locations associated with or mentioned in documents has been explored for decades. As one of the most popular online social network platforms, Twitter has attracted a large number of users who send millions of tweets on daily basis. Due to the world-wide coverage of its users and real-time freshness of tweets, location prediction on Twitter has gained significant attention in recent years. Research efforts are spent on dealing with new challenges and opportunities brought by the noisy, short, and context-rich nature of tweets. In this survey, we aim at offering an overall picture of location prediction on Twitter. Specifically, we concentrate on the prediction of user home locations, tweet locations, and mentioned locations. We first define the three tasks and review the evaluation metrics. By summarizing Twitter network, tweet content, and tweet context as potential inputs, we then structurally highlight how the problems depend on these inputs. Each dependency is illustrated by a comprehensive review of the corresponding strategies adopted in state-of-the-art approaches. In addition, we also briefly review two related problems, i.e., semantic location prediction and point-of-interest recommendation. Finally, we make a conclusion of the survey and list future research directions. [ABSTRACT FROM AUTHOR] more...

This article puts the second-order theory for regional elections to the test. Not by analysing voting behaviour but with the use of campaign data. The assumption that regional campaigns are overshadowed by national issues was verified by analysing the campaign tweets of Flemish politicians who ran for the regional or national parliament in the simultaneous elections of 2014. No proof was found for a hierarchy of electoral levels but politicians clearly mix up both levels in their tweets when elections coincide. The extent to which candidates mix up governmental levels can be explained by the incumbency past of the candidates, their regionalist ideology, and the political experience of the candidates.

This study investigates networked framing of terrorism news in Twitter by distinguishing three proximity effects (geographic, social, and temporal proximity) on audience and media institutional frames (i.e., episodic/thematic and space frames), based on construal-level theory. An analysis of tweets during the Boston Marathon bombing and the Brussels Airport attack finds that institutional and audience frames show similarity but do not always converge on Twitter. Similarities in the audience and institutional frames are attributed to a universal human tendency for social categorization, inherent in the minds of not only ordinary citizens but also journalists. Proximity effects, however, were more salient on audience frames than on institutional frames. [ABSTRACT FROM AUTHOR] more...

Anonymous social media platforms, like Secret, Yik Yak, and Whisper, have emerged as important tools for sharing ideas without the fear of judgment. Such anonymous platforms are also important in nations under authoritarian rule, where freedom of expression and the personal safety of message that authors may depend on anonymity. Whether for fear of judgment or retribution, it is sometimes crucial to hide the identities of users who post sensitive messages. In this paper, we consider a global adversary who wishes to identify the author of a message; it observes either a snapshot of the spread of a message at a certain time or sampled timestamp metadata, or both. Recent advances in rumor source detection show that existing messaging protocols are vulnerable against such an adversary. We introduce a novel messaging protocol, which we call adaptive diffusion, and show that under the snapshot adversarial model, adaptive diffusion spreads content fast and achieves perfect obfuscation of the source when the underlying contact network is an infinite regular tree. That is, all users with the message are nearly equally likely to have been the origin of the message. When the contact network is an irregular tree, we characterize the probability of maximum likelihood detection by proving a concentration result over Galton–Watson trees. Experiments on a sampled Facebook network demonstrate that adaptive diffusion effectively hides the location of the source even when the graph is finite, is irregular, and has cycles.

Brand managers use celebrity microbloggers to endorse their products on microblogs. Previous studies on celebrity endorsement mechanisms concentrated on source factors such as celebrity's characteristics and celebrity-product congruence. This study introduces a new audience factor: the fan-celebrity parasocial interaction (PSI) to explore the celebrity endorsement mechanism within a microblog context. The study hypothesizes that PSI and source factors (credibility, attractiveness, and congruence) significantly influence endorsement effectiveness. The results of an online survey ( N = 862) indicate that PSI and celebrity-product congruence are salient antecedents of endorsement effectiveness. PSI serves as a mediator of the effect of source attractiveness on endorsement effectiveness. Source credibility and celebrity-product congruence are mediators between PSI and endorsement effectiveness. The study develops and tests a conceptual model to illustrate the influential mechanism of celebrity endorsement on microblog platforms. [ABSTRACT FROM AUTHOR] more...

Researchers have noted that an individual’s processing of political media messages occurs through various filters including partisanship, interest, and cynicism. The phenomenon of motivated processing, however, is understudied particularly in the context of televised presidential debates. As major campaign events, presidential debates have been linked to increases in viewers’ political knowledge, political information efficacy, and changes in candidate evaluation. Yet individual’s information processing, largely unexplored in the extant debate literature, may well influence these outcomes. In the present study, we manipulate processing of a political debate and monitor the effects through participant engagement with social media. Researchers asked debate viewers to tweet while watching 2016 Democrat and Republican presidential primary debates following instructions designed to prime either directional motivated processing or accuracy motivated processing. The results demonstrate that the accuracy prompt reduced issue-based tweeting and therefore reduced knowledge acquisition. Conversely, the directional prompt increased issue-based tweeting and therefore increased knowledge acquisition. [ABSTRACT FROM AUTHOR] more...

Research suggests that the experience of interpersonal racism increases target group individuals’ engagement in health-impairing behavior. While becoming relatively less visible in face-to-face communication contexts, overt racism is finding its “niche” in social media. Drawing on the general strain theory, we examined whether and how microblogged racist messages increase target group members’ intention to drink alcohol through negative emotions. In an online experiment conducted with a general adult sample of 211 Asians living in the United States, participants were randomly exposed to one of three stimuli—control (nonracist) tweets versus anti-Asian tweets versus anti-Asian retweets—and reported their affective states. Next, participants performed a drink choice task disguised as a consumer survey. Results showed that microblogged racist messages indirectly influenced drinking intention in two causal pathways: through anger and serially through shame and anger. The impact and implications of racist messages generated and disseminated through social media platforms are discussed. [ABSTRACT FROM AUTHOR] more...

Research on microblogging in education has suggested its potential to promote community building and collaborative learning, but little is known about the nature of interaction in such microblogging communities. More research is needed to understand how online learning communities can be designed in a way that supports effective learning. The purpose of the study is to explore how people interact in a popular microblogging-based learning community by examining a one-hour synchronous chat event and analyzing its network structure, levels of participation, major topics generated and types of interaction. The findings suggested that the levels of participation in the synchronous chat were largely uneven. During the chat, participants were engaged in many types of interaction and discussed a variety of issues related to the topic. Interestingly, people who were different in their levels of participation also varied on the types of topics generated, but not on the types of interaction. [ABSTRACT FROM AUTHOR] more...

This article introduces a group of politically charged Twitter users that deviates from elite and ordinary users. After mining 20 M tweets related to nearly 200 instances of political protest from 2009 to 2013, we identified a network of individuals tweeting across geographically distant protest hashtags and revisited the term “serial activists.” We contacted 191 individuals and conducted 21 in-depth, semi-structured interviews thematically coded to provide a typology of serial activists and their struggles with institutionalized power. We found that these users have an ordinary following, but bridge disparate language communities and facilitate collective action by virtue of their dedication to multiple causes. Serial activists differ from influentials or traditional grassroots activists and their activity challenges Twitter scholarship foregrounding the two-step flow model of communication. The results add a much needed depth to the prevalent data-driven treatment of political Twitter by describing a class of extraordinarily prolific users beyond influentials and the twittertariat.

We analyse the use of Twitter in political communication in Switzerland because, in comparison with other democracies, Switzerland with its strong federalism, fragmented party system, small country size and semi-professional politicians can be seen as the least-likely critical case, thus creating unique conditions for the use of social media. The study investigates the individual characteristics of Swiss Members of Parliament that could influence social media usage. Thus, the study contributes to the debate about equalization and normalization with respect to Twitter as a relevant microblogging channel for political communication and to the significance of country-specific conditions for the adoption of innovations in political online communication. The study explains the shift from equalization towards normalization with the diffusion of innovations theory. [ABSTRACT FROM AUTHOR] more...

This study is built around the appointment of a dedicated “conversation manager” at the Flemish public broadcaster VRT. We focus on (1) the impact of the conversation manager on Twitter activity of the viewers and (2) the impact of the tweeting audience in the newsroom. Our framework combines journalistic as well as social media logics in Bourdieu’s field framework, for which we combine Twitter data and newsroom inquiry. The network analysis of Twitter activity shows the impact of the conversation manager, although his activities are primarily guided by traditional journalistic values. In turn, the tweeting audience impacts newsroom practices, predominantly as an indicator of audience appreciation. To conclude, social media data further complicate the definition and understanding of “the public.” [ABSTRACT FROM AUTHOR] more...

In this paper, we propose a semantic approach for monitoring information published on social networks about a specific event. In the era of Big Data, when an emergency occurs information posted on social networks becomes more and more helpful for emergency operators. As direct witnesses of the situation, people share photos, videos or text messages about events that call their attention. In the emergency operation center, these data can be collected and integrated within the management process to improve the overall understanding of the situation and in particular of the citizen reactions. To support the tracking and analyzing of social network activities, there are already monitoring tools that combine visualization techniques with geographical maps. However, tweets are written from the perspective of citizens and the information they provide might be inaccurate, irrelevant or false. Our approach tries to deal with data relevance proposing an innovative ontology-based method for filtering tweets and extracting meaningful topics depending on their semantic content. In this way data become relevant for the operators to make decisions. Two real cases used to test its applicability showed that different visualization techniques might be needed to support situation awareness. This ontology-based approach can be generalized for analyzing the information flow about other domains of application changing the underlying knowledge base. [ABSTRACT FROM AUTHOR] more...

The recent sacking of the eminent scientist Tim Hunt from one of the United Kingdom’s leading research institutions is only the latest in a series of cases where public individuals have been derided for comments made in jest on social media, with serious consequences for their professional and personal lives. This article discusses the case of Tim Hunt as an example of the extent to which the privileging of the correct over the true which has long pervaded media discourse is taken to the extreme by the instant-response culture of social media. It points to the emergence of a new form of instantaneity enabled by these networked forms of communication that serves to reinforce systemic inaction rather than the change widely associated with these technologies. It draws on philosophy and critical theory as useful conceptual frameworks for highlighting the ways in which Twitter and co. increasingly call us to action but crowd out thought, thereby passing over opportunities for real social change.

The widespread adoption of the Internet offers tangible potential for increasing political participation through disseminating digital reminders to vote. This study presents three experiments in which confederates mobilize members of their networks to vote by tagging them in Facebook status updates. Relying on the technological affordances of Facebook, treatments publicize individuals' past participation or failure to vote in an ongoing election. The results show substantial increases in turnout greater than that which is usually produced by face-to-face methods. Findings suggest that digital media offer citizens the potential to generate tremendous gains in voter participation, and address concerns that our increasingly digitally networked society may prove harmful to democracy.

Online social networks greatly facilitate social exchange among friends. At times, for amusement, individuals may be targeted by friends' playful teases, which often involve exposing individuals' private embarrassing information, such as information that reveals their past indecent behavior, mischief, or clumsiness. Although individuals sometimes do enjoy the humor, they might also be offended by the involuntary exposure. Drawing on social exchange theory, this paper elucidates the consequences of an embarrassing exposure in online social networks. Specifically, this study examines the effects of information dissemination and network commonality on individuals' exchange assessment as well as how this assessment shapes their behavioral responses. The results of our experiment provide strong evidence that information dissemination and network commonality jointly influence individuals' perceived privacy invasion and perceived relationship bonding. In addition, whereas perceived privacy invasion increases transactional avoidance, it reduces approach behavior. Furthermore, whereas perceived relationship bonding impedes both transactional avoidance and interpersonal avoidance, it leads to approach behavior. The theoretical and practical implications of the findings are discussed. [ABSTRACT FROM AUTHOR] more...

Prosecutors' extrajudicial speech is not a new problem. Indeed, prosecutors' out-of-court statements to the press and the public at large have been of concern for over a century. Consequently, ethical rules and standards have been implemented to protect defendants from undue reputational harm and to strike a balance between trial participants' right to free speech and defendants' right to due process. Although these rules and standards are periodically revised, they have not yet accounted for the differences between traditional media -- for which the rules and standards were written -- and social media. Recently, however, prosecutors have used social media to discuss pending cases and other aspects of the prosecutorial function, raising concern over how social media may magnify both the benefits and the risks of harm associated with prosecutors' extrajudicial statements. This Note analyzes the differences between traditional media and social media, as well as how those differences impact the effect of prosecutors' extrajudicial speech on pending matters, the reputation of the accused, and public perception of prosecutors and the justice system as a whole. This Note argues that the increased risks of harm presented by prosecutors' use of social media necessitate new restraints to restore the free speech/fair trial balance and promote professionalism in the social media age.

In China, microblogging is an extremely popular activity and is proving to be an effective mechanism to gauge perceptions about social phenomena. Between 2010 and 2015 Sina Weibo, China's largest microblogging website, generated 95,015 postings from 62,074 users referencing the term massive open online courses (MOOCs), a method of online course delivery popularized in North America that has spread globally. Time series analyses revealed distinct patterns in the volume of postings during a four-year period, and subsequently by month, by week, and by the time of day. The volume of postings during the week, for example, peaked on Monday and declined daily to a low point on Saturday. Relative to maximizing learner engagement, the findings may provide insight to parties who deliver MOOCs to employ or test strategies on timing (i.e., time of year to offer/not offer a MOOC, time of week to release/not release new material, time of day to schedule/not schedule chat sessions). The paper also serves to demonstrate a mechanism to retrieve big data from social media sources, otherwise underutilized in educational research. [ABSTRACT FROM AUTHOR] more...

Since the 1990s, China has witnessed a rapid rise in urban contention, which has become increasingly apparent. This study proposes a co-empowerment model regarding the relationship between the Chinese media and contentious politics. It compares two recent cases of urban contention. On the one hand, protestors leverage media exposure to arouse public attention, organize action, and adjust their actions according to the information revealed by the media; on the other hand, the media are empowered to exploit the limited space in news coverage, protect their professional integrity, enhance their credibility, and develop close ties with the civil society. This mutually strengthening process is the most important feature of the co-empowerment model. The co-empowerment model influences the trajectories of contention and facilitates greater media autonomy in an authoritarian regime. This study's contribution is a thematic analysis of the co-empowering relationship between media and urban contention in illiberal states. [ABSTRACT FROM AUTHOR] more...

The rise of social media, such as blogs, social network sites, Twitter, and YouTube, encourages hope for renewed confidence in the government and news media because these venues connect users directly to candidates and officeholders. This article indicates that blogs most heavily relied on the type of social media for political information. Moreover, reliance on blogs and YouTube leads to reduced confidence in the presidency, Congress, and the news media, but reliance on social network sites and Twitter leads to higher confidence in these institutions after controlling for strength of party ties, political ideology, political interest, reliance on traditional media, and demographic variables.

We demonstrate the power of data mining techniques for the analysis of collective social dynamics within British Tweets during the Olympic Games 2012. The classification accuracy of online activities related to the successes of British athletes significantly improved when emotional components of tweets were taken into account, but employing emotional variables for activity prediction decreased the classifiers' quality. The approach could be easily adopted for any prediction or classification study with a set of problem-specific variables. [ABSTRACT FROM AUTHOR] more...

With the rapid proliferation of online-blogging and micro-blogging websites, millions of text posts are generated and made available online every day. Utilizing this rich data channel could facilitate educated purchasing of items, discovering trends and public tendencies regarding various products available in the market, discovering political inclination of societies prior to a national election, etc. Since the last decade, Sentiment Analysis (SA) has received increased attention from many researchers as a method for addressing topics, such as the aforementioned ones. This paper focuses on SA using sentiment features and patterns. We propose different sentiment polarity detection methods, two unsupervised methods and one supervised, which we compare with two baseline methods, a state-of-the-art Support Vector Machine (SVM) classifier trained on a unigram bag-of-words model, and an unsupervised SentiStrength [38] algorithm. In our experiments, we show that our polarity detection methods are highly effective and can outperform the aforementioned baselines in most of our conducted experiments.

Kuwait boasts high levels of political and media freedoms compared to many countries in the Middle East, and it enjoys a vibrant social media scene. The Kuwaiti parliamentary election in February 2012 was the first election in which candidates widely utilized Twitter during their campaigns. This article presents a content analysis of tweets sent by the 50 winning members of parliament (MPs) during the campaign period. It seeks to ascertain the Twitter usage patterns of MPs and determine whether Twitter was an effective tool in gaining votes. Although Twitter was widely used among MPs, it was employed less for information sharing or communicating about political issues and more for engaging with followers. This article concludes that no relationship existed between using Twitter and gaining votes. Rather, the social media platform acted as a natural extension of off-line interactions between MPs and the electorate. [ABSTRACT FROM AUTHOR] more...

This study explores the use of Twitter by political reporters and commentators—an understudied population within the rapidly growing literature on digital journalism—covering the 2012 Republican and Democratic conventions. In particular, we want to know if and how the “affordances” of Twitter are shaping the traditional norms and routines of US campaign reporting surrounding objectivity, transparency, gatekeeping, and horse race coverage, and whether Twitter is bursting the “bubble” of insider talk among reporters and the campaigns they cover. A sample derived from all tweets by over 400 political journalists reveals a significant amount of opinion expression in reporters' tweets, but little use of Twitter in ways that improve transparency or disrupt journalists' (and campaigns') role as gatekeepers of campaign news. Overall, particularly when looking at what political journalists retweet and what they link to via Twitter, the campaign “bubble” seems at the moment to have remained largely intact.

Being aware of local community information is critical to maintaining civic engagement and participation. The use of online news and microblog content to create and disseminate community information has long been studied. However, interactions in the online spaces dedicated to local communities tend to only garner very limited usage, and people often do not consider microblog content as a meaningful source of local community information. Local News Chatter (LNC) was designed to address these challenges by augmenting local news feeds with microblog content and presenting them in a tag cloud that displays news topics of varying popularity with different tag sizes. Our study with 30 local residents highlights that LNC increases the visibility of hyperlocal community news information and successfully utilizes microblog as an additional information layer. LNC also increases one’s community awareness and shows the potential for leveraging community knowledge as a deliberation platform for local topics. [ABSTRACT FROM AUTHOR] more...

The increasing use of micro-blogging as a marketing tool has increased research attention on usage and business value of enterprise micro-blogging. Based on research on information system (IS) usage and resourcebased view (RBV) theory, this study develops a model to reveal the mechanism of business value creation of enterprise micro-blogging. The model consists of metrics on micro-blogging usage, micro-blogging operational performance, marketing capability, and firm performance. Questionnaires were distributed to firms that use micro-blogging. This study collects 241 valid responses for empirical analysis. The results suggest that the use of enterprise micro-blogging improves operational performance of enterprise micro-blogging directly and indirectly by increasing marketing capability, while operational performance of enterprise micro-blogging significantly affects firm performance. This study extends the stream of research that combines IS usage and RBV theory. [ABSTRACT FROM AUTHOR] more...

This study of adolescent social drama is located at the intersection of research on adolescent peer relationships, group behaviors, youth culture, and mediated communication. An emergent construct, drama has been conceptualized as social interactions characterized by overreaction, exaggeration, excessive emotionality, prolongation, inclusion of extraneous individuals, inflated importance, and temporary relevance. This case study and participant observation involve a 15-year-old, white, middle class female and her mother. The purpose was two-fold: To determine if the events described map on to existing understandings of drama and to develop emergent themes and hypotheses through grounded theory analysis and ethnographic observation that might expand knowledge of drama. Findings suggest that this case reflects current understandings of drama. Emergent themes suggest that drama may also involve highly emotional group experiences and that while drama may be temporary and short-lived, it may also create a backdrop for additional problematic events.

This article studies communication activities in the do-it-yourself air quality testing initiatives in multiple cities in China, through interviews with leaders of small nongovernmental organizations (NGOs) and analyses of their blogging contents. To advocate for more transparency in pollution data, in particular the hazardous PM2.5 particles, environmental NGOs mobilized volunteers to measure air quality and post the results online. The article examines how the DIY activism constitutes citizen participation and political involvement through informal and diffused ways of collective action. It studies the role of the Internet in facilitating the formation of a collective identity, which might be temporary and fragile. The article also discusses how grassroots DIY activities in a post-Communist country like China differ from those in the West. [ABSTRACT FROM AUTHOR] more...

The present study has two main objectives. First, to examine how alcohol use is portrayed in the visual and textual references on Facebook, and second, to determine how friends react to these alcohol-related postings. A theoretically based content analysis of 160 Facebook profiles generated 2,575 pictures and 92 status updates referring to alcohol use, which represented about 6.50% of the pictures in the total sample and 2.90% of the status updates. These visual and textual references, as well as the peer reactions to these posts, mostly referred to alcohol use in a positive context (72.23% of the pictures and 72.83% of the messages). Furthermore, multiple regression analyses identified the number of Facebook friends and the number of status updates referring to alcohol use as significant predictors of the total number of uploaded pictures containing alcohol use. The results of this study are discussed within the framework of expectancy models of behavior and media effects theories, and show that alcohol-related references are quite common, while negative reactions to these posts are seldom. Further research into the effects of these visual and textual messages is warranted. [ABSTRACT FROM AUTHOR] more...

This article reflects on some of the issues involved in teaching Chinese politics in the west and assesses the rationale for incorporating technology into teaching. The article specifically addresses the potential benefits of using microblogging (Twitter and Weibo) as a supplementary teaching tool in Chinese politics classes. The article argues that microblogging has benefits in terms of helping students develop professional networks, extending contact hours without placing an onerous burden on instructors, contributing to the construction of a supportive and collaborative learning environment and demystifying China for non-Chinese majors. Furthermore, in classes where students possess Chinese language skills, China's domestic Weibo provide a fascinating window onto social and political issues as they are experienced contemporaneously by Chinese netizens. An assessment of the potential uses of microblogging is timely as the learning preferences of current and future cohorts change and commercial and pedagogical imperatives increasingly impel university teachers to consider the effectiveness of their teaching methods.

Purpose – The purpose of this paper is to propose a conceptual model to investigate the determinants of information retweeting in microblogging based on Heuristic-Systematic Model. Design/methodology/approach – Microblogging data about emergency events from Sina microblogging (http://weibo.com) are collected and analyzed with text mining technology. The proposed hypotheses are tested with logistic and multiple linear regressions. Findings – The results show that source trustworthiness, source expertise, source attractiveness, and the number of multimedia have significant effects on the information retweeting. In addition, source expertise moderates the effects of user trustworthiness and content objectivity on the information retweeting in microblogging. Practical implications – This study provides an in-depth understanding of what makes information about emergency events in microblogging diffuse so rapidly. Based on these findings the emergency management organizations in China can apply the microblogging to spread useful information, and these findings also provide practical implications for microblogging system designers. Originality/value – The primary value of this paper lies in providing a better understanding of information retweeting in microblogging based on Heuristic-Systematic Model. Organizations that would like to adopt the microblogging platform in emergency situations to improve the ability of emergency response can benefit from the findings of this study.

This study critically analyzed the current body of published research on microblogging in education ( MIE) to build a deep and comprehensive understanding of this increasingly popular phenomenon. Twenty-one studies on MIE in 2008-2011 were selected based on the selection criteria and analyzed to answer the following questions: What types of research have been published on MIE? How was microblogging used for teaching and learning in these studies? What educational benefits did microblogging have on teaching and learning? What suggestions and implications did the current research have for future MIE research and practices? The analysis suggests that microblogging has a potential to encourage participation, engagement, reflective thinking as well as collaborative learning under different learning settings. The quality of research, however, varies greatly, suggesting a need for rigorous research on MIE. The analysis has implications for MIE practices as well as research and development efforts. Practitioner Notes What is already known about this topic Microblogging has a potential to facilitate learning., Research on microblogging has been conducted under different educational settings., What this paper adds What are the characteristics of the current research on microblogging in education., How educators and researchers integrated microblogging to achieve different educational goals as identified in these studies., What are the identified educational effects of using microblogging for teaching and learning., What are the challenges and suggestions of using microblogging in teaching and learning., Implications for practice and/or policy Future research on microblogging in education should go beyond formal higher education settings by considering learning occurring in other settings., Future research needs to observe and analyze how learners participate and learn in microblogging-based environments over time., Innovative data collection and analysis methods are needed to understand the interaction and learning that occur in such environments., Future research is needed to identify effective approaches of microblogging integration.
