'''How Do Twitter, Wikipedia, and Harrison's Principles of Medicine Describe Heart Attacks?''' - scientific work related to [[Wikipedia quality]] published in 2015, written by [[Nikhil Devraj]] and [[Michael Chary]].

== Overview ==
Social media, such as [[Wikipedia]] and [[Twitter]], are an increasingly common source of medical information, including for medical students. It is unknown how medical information in social media compares to medical information in medical textbooks. Here authors compare Wikipedia articles on heart attacks and palpitations and tweets mentioning heart attacks and palpitations to chapters from Harrison's Principles of Internal Medicine and Braunwald's Heart Disease on myocardial infarction and cardiac dysrhythmias. For heart attacks, the chapters from Harrison's had higher Jaccard similarity to Wikipedia than Braunwald's or Twitter. For palpitations, no pair of sources had a higher Jaccard (token) similarity than any other pair. For no source was the Jaccard (token) similarity attributable to [[semantic similarity]]. This suggests that technical and popular sources of medical information focus on different aspects of medicine, rather than one describing a simplified version of the other. Authors hope work motivates further investigation into the representation of medical knowledge in different media.
