社交媒体(如Facebook和YouTube)使用在线和移动技术，允许个人参与、评论和创建用户生成的内容。Twitter是一个被广泛使用的社交媒体平台，用户可以发布基于公开文本的短消息，称为推文，其他用户可以对此做出回应。除了传统媒体，推特一直是关于英格兰国民医疗服务(NHS)有争议的激进改革的讨论焦点，这些改革最近由现任联合政府通过成为法律。查看了超过12万条关于医疗改革的推文，我们调查了是否可以获得关于Twitter在告知、辩论和影响特定医疗政策领域的意见方面的任何见解。特别是，我们研究了推文的情绪随着议会通过《健康和社会护理法案》而发生的变化，以及与同期进行的传统民意调查相比有何不同。我们调查了哪些用户似乎在推特上拥有最大的影响力，并建议如何使用一种广泛使用的学术影响力指标--H指数--来衡量Twitter上依赖于语境的影响力。(C)2013爱思唯尔爱尔兰有限公司。保留所有权利。
Social media (for example Facebook and YouTube) uses online and mobile technologies to allow individuals to participate in, comment on and create user-generated content. Twitter is a widely used social media platform that lets users post short publicly available text-based messages called tweets that other users can respond to. Alongside traditional media outlets, Twitter has been a focus for discussions about the controversial and radical reforms to the National Health Service (NHS) in England that were recently passed into law by the current coalition Government. Looking at over 120,000 tweets made about the health reforms, we have investigated whether any insights can be obtained about the role of Twitter in informing, debating and influencing opinion in a specific area of health policy. In particular we have looked at how the sentiment of tweets changed with the passage of the Health and Social Care Bill through Parliament, and how this compared to conventional opinion polls taken over the same time period. We examine which users appeared to have the most influence in the 'Twittersphere' and suggest how a widely used metric of academic impact - the H-index - could be applied to measure context-dependent influence on Twitter.
