News articles are extremely time sensitive by nature. There is also intense competition among news items to propagate as widely possible. Hence, the task of predicting popularity on social web both interesting and challenging. Prior research has dealt with eventual online based early popularity.

Social media offer an unprecedented opportunity to explore how people talk about health care at a very large scale. Numerous studies have shown the importance of websites with user forums for seeking information related health. Parents turn some these sites, colloquially referred as "mommy blogs," share concerns children's care, including vaccination. Although substantial work has considered role social media, particularly Twitter, in discussions vaccination and other care-related issues,...
Twitter has undoubtedly caught the attention of both general public, and academia as a microblogging service worthy study attention. several features that sets it apart from other social media/networking sites, including its 140 character limit on each user's message (tweet), unique combination avenues via which information is shared: directed network friends followers, where messages posted by user broadcast to all public timeline, provides real time access posts or tweets specific topics...
An analysis of more than eight years data from vaccination forums on mothering.com shows that the antivaccination movement is well-organized and widely dispersed, it emerged long before concerns about immunity were expressed. The findings are evidence a formidable challenge to social norms surrounding vaccination.
Reader reviews of literary fiction on social media, especially those in persistent, dedicated forums, create and are turn driven by underlying narrative frameworks. In their comments about a novel, readers generally include only subset characters relationships, thus offering limited perspective that work. Yet aggregate, these capture an framework comprised different actants (people, places, things), roles, interactions we label the "consensus framework". We represent this form...
Objective: To examine the relationship between mental health treatment and employee retention. Study Design: Retrospective Cohort Methods: 14 companies (184,715 employees) were studied evaluating retention among individuals who used an evidence-based benefit. Among three provided plan claims (n=24,947), we compared 1,966 employees benefit 1,063 had usual care. Survival analysis was to compare probability of staying at company for two cohorts. Cox Proportional Hazards Models evaluate hazard...
We propose an automated and unsupervised methodology for a novel summarization of group behavior based on content preference. show that graph theoretical community evolution (based similarity user preference content) is effective in indexing these dynamics. Combined with text analysis targets automatically-identified representative each community, our method produces multi-layered representation evolving behavior. demonstrate this the context political discourse social news site data spans...
