"She seems more human" : understanding Twitter users' credibility assessments of dementia-related information
The presence of incorrect, medically uncorroborated information on social media may be harmful if people believe it. The purpose of this qualitative study was to identify how Twitter users evaluate the credibility of dementia-related information sources. It used a think-aloud protocol via semi-structured interviews with 13 caregivers. It identified main credibility dimensions, including 13 factors. Participants deployed a combination of heuristics to assess information sources, and engaged in intensive systematic content review based on prior knowledge and relevance. The findings con-tribute to a nuanced understanding of how users evaluate Twitter sources in the health domain. Some of these are discussed in light of the MAIN Model, and prove significant in how practitioners and developers can better under-stand and help users evaluate information
Tweet, but Verify: Epistemic Study of Information Verification on Twitter
While Twitter provides an unprecedented opportunity to learn about breaking
news and current events as they happen, it often produces skepticism among
users as not all the information is accurate but also hoaxes are sometimes
spread. While avoiding the diffusion of hoaxes is a major concern during
fast-paced events such as natural disasters, the study of how users trust and
verify information from tweets in these contexts has received little attention
so far. We survey users on credibility perceptions regarding witness pictures
posted on Twitter related to Hurricane Sandy. By examining credibility
perceptions on features suggested for information verification in the field of
Epistemology, we evaluate their accuracy in determining whether pictures were
real or fake compared to professional evaluations performed by experts. Our
study unveils insight about tweet presentation, as well as features that users
should look at when assessing the veracity of tweets in the context of
fast-paced events. Some of our main findings include that while author details
not readily available on Twitter feeds should be emphasized in order to
facilitate verification of tweets, showing multiple tweets corroborating a fact
misleads users to trusting what actually is a hoax. We contrast some of the
behavioral patterns found on tweets with literature in Psychology research.Comment: Pre-print of paper accepted to Social Network Analysis and Mining

Do You Trust Me(dia)?: How Students Perceive and Identify Fake News
Social media has become an increasingly popular source of news among young adults. However, with the rise of âfake news,â credibility comes into question and young adults are left on their own to determine which news is real and which is false. Two focus groups were employed in this study to gain a greater understanding of how college students aged 18-24 determine what news to trust on social media and the factors that impacted those decisions. Young adults in that age group trust news found on social media based on a variety of factors including the person that is sharing the news, the particular social media site it comes from, and the ability to verify the news with other alternative sources

Street cred : are media consumers craving more âauthenticityâ in the digital age?
Media organizations that provide news have traditionally relied on audience perceptions of truth and credibility to lure more readers, viewers, and listeners. The author explores whether authenticity has emerged in the digital age as an additional ingredient in media consumersâ daily decisions about where to turn â and where to return â for trustworthy information. As it becomes ever-more of a challenge for consumers to distinguish reliable information from âfake newsâ in the 21st century, audiences may be seeking content from media organizations that feels more authentic, genuine, and personalized. Three case studies drawn from new media, as well as legacy media, help illustrate what traditional and startup media institutions can do to better understand audience attitudes and behaviors: the HBO series âLast Week Tonight with John Oliver,â the online site Reddit, and the Pulitzer Prize-winning work of Washington Post reporter David Fahrenthold.Communication Studie
Twitter and the Question of Objectivity: How Social Network Sites Influence a Journalistic Norm
This research paper deals with the validity of the journalistic norm objectivity within the newly evolving context of online social network sites, in particular Twitter. I propose that social network sites are one of todayâs primary battlefields on which the fight between supporters and critics of objectivity takes place. I further argue that journalism should loosen up its frenetic grip on objectivity and allow for more value-laden writing, partly because social network sites have put a new tool into journalistsâ hands: journalists can use Twitter as a new and innovative âquote boxâ by accessing tweets of politicians, athletes, celebrities, and other people alike; they can employ Twitter to exchange information with other journalists around the world; and they can easily access and deliver information as it happens. Further, Twitter proves to be helpful for consumers: they can follow a variety of news sources at the same time; they can directly interact with professional journalists; and they can act themselves as citizen journalists. The facilitated interaction between journalists and consumers, who are increasingly looking for opinionated writing, is at the core of my claim for a less rigid reign of journalistic objectivity in favor of more value-laden reporting. Social network sites present us with a new environment in which the rules of journalistic communication have been completely altered. An appropriate communication in these online communities matters to uphold journalistic credibility and to evolve journalistic work. This can be achieved through accepting journalistic subjectivity as a complement to objectivity
$1.00 per RT #BostonMarathon #PrayForBoston: analyzing fake content on Twitter
This study found that 29% of the most viral content on Twitter during the Boston bombing crisis were rumors and fake content.AbstractOnline social media has emerged as one of the prominent channels for dissemination of information during real world events. Malicious content is posted online during events, which can result in damage, chaos and monetary losses in the real world. We analyzed one such media i.e. Twitter, for content generated during the event of Boston Marathon Blasts, that occurred on April, 15th, 2013. A lot of fake content and malicious profiles originated on Twitter network during this event. The aim of this work is to perform in-depth characterization of what factors influenced in malicious content and profiles becoming viral. Our results showed that 29% of the most viral content on Twitter, during the Boston crisis were rumors and fake content; while 51% was generic opinions and comments; and rest was true information. We found that large number of users with high social reputation and verified accounts were responsible for spreading the fake content. Next, we used regression prediction model, to verify that, overall impact of all users who propagate the fake content at a given time, can be used to estimate the growth of that content in future. Many malicious accounts were created on Twitter during the Boston event, that were later suspended by Twitter. We identified over six thousand such user profiles, we observed that the creation of such profiles surged considerably right after the blasts occurred. We identified closed community structure and star formation in the interaction network of these suspended profiles amongst themselves
Assessing the credibility of online social network messages.
ABSTRACT Information gathered socially online is a key feature of the growth and development of modern society. Presently the Internet is a platform for the distribution of data. Millions of people use Online Social Networks daily as a tool to get updated with social, political, educational or other occurrences. In many cases information derived from an Online Social Network is acted upon and often shared with other networks, without further assessments or judgments. Many people do not check to see if the information shared is credible. A user may trust the information generated by a close friend without questioning its credibility, in contrast to a message generated by an unknown user. This work considers the concept of credibility in the wider sense, by proposing whether a user can trust the service provider or even the information itself. Two key components of credibility have been explored; trustworthiness and expertise. Credibility has been researched in the past using Twitter as a validation tool. The research was focused on automatic methods of assessing the credibility of sets of tweets using analysis of microblog postings related to trending topics to determine the credibility of tweets. This research develops a framework that can assist the assessment of the credibility of messages in Online Social Networks. Four types of credibility are explored (experienced, surface, reputed and presumed credibility) resulting in a credibility hierarchy. To determine the credibility of messages generated and distributed in Online Social Networks, a virtual network is created, which attributes nodes with individual views to generate messages in the network at random, recording data from a network and analysing the data based on the behaviour exhibited by agents (an agent-based modelling approach). The factors considered for the experiment design included; peer-to-peer networking, collaboration, opinion formation and network rewiring. The behaviour of agents, frequency in which messages are shared and used, the pathway of the messages and how this affects credibility of messages is also considered. A framework is designed and the resulting data are tested using the design. The resulting data generated validated the framework in part, supporting an approach whereby the concept of tagging the message status assists the understanding and application of the credibility hierarchy. Validation was carried out with Twitter data acquired through twitterâs Application Programming Interface (API). There were similarities in the generation and frequency of the message distributions in the network; these findings were also recorded and analysed using the framework proposed. Some limitations were encountered while acquiring data from Twitter, however, there was sufficient evidence of correlation between the simulated and real social network datasets to indicate the validity of the framework.N/
Social Media Influence: Metrics Matter
It is imperative for companies to engage in social media marketing as consumers are often dependent on online information and electronic word-of-mouth. Past literature claims that consumers evaluate the influence of communications differently on social media than they would in a traditional environment because of the nature of the internet. This study aims to analyze userâs perceptions of social media marketing influence and determines if userâs perception of influence changes based on the number of social media metrics (likes, comments, and shares) that accompany a Facebook post. The study also investigates if perceptions of influence vary depending on a userâs level of involvement in the situation. A 2x2 factorial design is utilized to manipulate both level of involvement and amount of likes, comments, and shares that accompany a Facebook post. The results contend that a high number of likes, comments, and shares on Facebook leads to increased perceptions of source credibility and information usefulness. In particular, the results prove that a high number of likes, comments, and shares on Facebook leads to increased purchase intention in a low-involvement situation. These results are essential to marketers as they prove the importance of curating engaging content on companyâs Facebook pages in order to generate high amounts of likes, comments, and shares. Increasing the amount of likes, comments, and shares on Facebook will make the post more influential to users
