“…An observation in some topics is the use of certain hashtags to identify a specific community of users [29], such as the #wlscommunity in the weight loss topics. Online health communities have been studied to understand social support and behavior change in managing health conditions [30].…”

Background: Social media provides a complementary source of information for public health surveillance. The dominate data source for this type of surveillance is the microblogging platform Twitter, which is convenient due to the free availability of public data. Less is known about the utility of other social media platforms, despite their popularity. Objective: This work aims to characterize the health topics that are prominently discussed in the image-sharing platform Instagram, as a step toward understanding how this data might be used for public health research. Methods: The study uses a topic modeling approach to discover topics in a dataset of 96,443 Instagram posts containing hashtags related to health. We use a polylingual topic model, originally developed for datasets in different natural languages, to model different modalities of data: hashtags, caption words, and image tags automatically extracted using a computer vision tool. Results: We identified 47 health-related topics in the data, covering ten broad categories: acute illness, alternative medicine, chronic illness and pain, diet, exercise, healthcare & medicine, mental health, musculoskeletal health and dermatology, sleep, and substance use. The most prevalent topics were related to diet and exercise. Conclusions: A large and diverse set of health topics are discussed in Instagram. The extracted image tags were generally too coarse and noisy to be used for identifying posts, but were in some cases accurate for identifying images relevant to studying diet and substance use. Instagram shows potential as a source of public health information, though limitations in data collection and metadata availability may limit its use in comparison to platforms like Twitter.

“…By joining either live conversations such as Twitter chats or contributing to issue focused hashtags, the practice enables the emergence and formation of issue publics (Highfield, 2012). Cook et al (2013) argue that Twitter chats, "periodic, synchronized group conversations focused on specific topics" (p. 1) are an unintended use of the platform. Their analysis of 1.4K group chats involving 2.3 million users indicates "the grassroots nature of these organized groups demarcates a subset of Twitter containing passionate users producing seemingly higher quality tweets" (p. 10).…”

#publicrelations on Twitter: Pushers, Talkers, Influencers on Spamming PR and Job Hunting

A space generally associated with marketers and breaking news (Hobsbawn, 2009 cited in Evans, Twomey & Talan, 2011, Twitter has also become a space debate, community building and legitimization for companies and social movements alike. The academic literature has seen a rise in interest in the micro-blogging platform. For instance, Adi and Moloney (2012) assess the strategic uses of Twitter by protest groups, Adi, Erickson and Lilleker (2014) reflect on the networks and use pattern of the same platform by politicians, namely UK Labor party representatives in the House of Lords while Adi and Grigore (2015) analyze the strategic uses of social media by corporations. Bajpai and Jaiswal (2011) on the other hand propose a framework for analyzing collective action events on Twitter and so do the creators behind visual analysis platforms like NodeXL, Gephi, Linkurious and Socioviz. Public Relations research too has provided several reflections and analyses of Twitter. Verhoeven et al (2012) and Sweetsner and Kelleher discuss how practitioners use social media; Lovejoy, Waters and Saxton evaluate how NGO are engaging stakeholders though the new medium, while Saffer, Sommerfeldt and Taylor (2013) suggest that Twitter interactivity influences the quality of organization-public relationships. With questions about the professionalization of Public Relations as well as about the portrayals and perceptions of the profession continuing to intrigue researchers, it is surprising that only Xifra and Grau (2010) looked into the type of information shared in tweets about public relations. Using the Twitter data collection and analysis option from Socioviz this paper provides an exploratory account of the #publicrelations on Twitter. Using the visualizations provided by the platform and automated data analysis to gain insight into over 10,000 tweets published during June 15-24 and July 15-24, this paper qualitatively assesses the emerging themes about public relations focusing on association of hashtags and type of messages shared and identifies the most active and most influential users within the issue topic. The paper reveals that the #publicrelations is often associated with #jobs or is hijacked and associated with tags such as #gossip or #entertainment. The paper also shows that conversation in the #publicrelations issue network is limited and that the hashtag only partially includes content relevant to the practice. In doing so the paper raises important questions about the nature of dialogue and symmetry on social media and their assessment and suggests that further research should explore twitter chats as well as continue to apply similar data collection methods as used for the study.

“…The use of hashtags in questions can serve dual roles [16,19], labeling a post's type/topic (i.e., that it is a question in need of reply) as well as flagging it for visibility to communities of users that monitor particular hashtags [3]. This latter role is potentially important for enabling users to truly harness the promise of social media to connect them to "weak ties" (or strangers), who tend to be sources of novel information [5].…”

In addition to posting news and status updates, many Twitter users post questions that seek various types of subjective and objective information. These questions are often labeled with "Q&A" hashtags, such as #lazyweb or #twoogle. We surveyed Twitter users and found they employ these Q&A hashtags both as a topical signifier (this tweet needs an answer!) and to reach out to those beyond their immediate followers (a community of helpful tweeters who monitor the hashtag). However, our log analysis of thousands of hashtagged Q&A exchanges reveals that nearly all replies to hashtagged questions come from a user's immediate follower network, contradicting users' beliefs that they are tapping into a larger community by tagging their question tweets. This finding has implications for designing next-generation social search systems that reach and engage a wide audience of answerers.
