用户生成的媒体及其对个人所接触的信息的影响可能会影响政治结果。这日益成为人们关注和关注的焦点。英国的欧盟成员国身份公投为研究人员提供了一个机会，让他们在充满政治色彩的情况下探索新信息圈的性质和影响。这项工作通过审查在公投前收集的180万不同用户的1320万条推文数据中链接的网站来做出贡献。在这个数据集中，48万用户根据他们的脱欧投票意图进行了分类。调查结果包括，推特上的链接材料大多是由那些支持脱离欧盟的人发布的。主流新闻媒体在推特链接数量方面的影响最大，替代媒体和竞选网站的影响要小得多。在15家关联度最高的主流媒体中，有一半对脱欧阵营的吸引力要大得多，其中两家的吸引力非常大。没有一家主流媒体在留欧支持者中有一致的吸引力。在受到这样或那样选民支持的网站中，退欧网站在推文中的出现次数方面影响最大。留下来的首选网站链接较少，主要是露骨的竞选网站。倾向于休假的网站链接更多，并由主流和另类媒体主导。
User generated media, and their influence on the information individuals are exposed to, have the potential to affect political outcomes. This is increasingly a focus for attention and concern. The British EU membership referendum provided an opportunity for researchers to explore the nature and impact of the new infosphere in a politically charged situation. This work contributes by reviewing websites that were linked in a Brexit Tweet dataset of 13.2 million tweets, by 1.8 million distinct users, collected in the run-up to the referendum. In this dataset, 480,000 users have been classified according to their “Brexit” vote intent. Findings include that linked material on Twitter was mostly posted by those in favour of leaving the EU. Mainstream news media had the greatest impact in terms of number of links tweeted, with alternative media and campaign sites appearing to a much lesser extent. Of the 15 most linked mainstream media, half show a substantially greater appeal to the leave camp, with two of them very much so. No mainstream media had a consistent appeal among remain supporters. Among the sites that were highly favoured by one voter valence or the other, the leave sites had by far the greatest impact in terms of number of appearances in tweets. Remain-preferred sites were less linked, and dominated by explicit campaign sites. Leave-preferred sites were more numerously linked, and dominated by mainstream and alternative media.
