论文摘要
几十年来，网络平台允许政治表现和辩论。技术变化带来了新的表达机会，这些辩论的纵向数据的可用性引起了有关谁参与的新问题，以及谁更新了他们的意见。这项工作的目的是提供一种测量这些现象的方法，并在最受欢迎的微博平台之一上观察到的那样，在特定主题（堕胎）上测试这种方法。为此，我们在2015年至2018年的两个讲西班牙语国家的Twitter上讨论了关于堕胎的讨论。我们的主要见解是两倍。一方面，人们采用了新技术来表达自己的立场，尤其是心脏表情符号（[绿心脏]和[紫色心脏））的彩色变化，以反映堕胎的身体表现。另一方面，即使在有强烈意见的问题上，观点也会改变，这些变化也会显示出人口群体的差异。这些发现表明，网络上的辩论包含了新的立场遵守方式，并且可以衡量和表征意见的变化。
Web platforms have allowed political manifestation and debate for decades. Technology changes have brought new opportunities for expression, and the availability of longitudinal data of these debates entice new questions regarding who participates, and who updates their opinion. The aim of this work is to provide a methodology to measure these phenomena, and to test this methodology on a specific topic, abortion, as observed on one of the most popular micro-blogging platforms. To do so, we followed the discussion on Twitter about abortion in two Spanish-speaking countries from 2015 to 2018. Our main insights are two fold. On the one hand, people adopted new technologies to express their stances, particularly colored variations of heart emojis ([green heart] & [purple heart]) in a way that mirrored physical manifestations on abortion. On the other hand, even on issues with strong opinions, opinions can change, and these changes show differences in demographic groups. These findings imply that debate on the Web embraces new ways of stance adherence, and that changes of opinion can be measured and characterized.
