AI总结：
本文提出新颖的多语言立场检测方法，分析乌克兰危机期间欧洲新闻与社交媒体上的移民讨论，发现讨论存在重新框定现象，且战争爆发前后立场发生明显时间性转变，但国家差异显著。
摘要：
乌克兰战争似乎已经积极地改变了欧洲对待移民这一关键社会议题的态度——至少对来自乌克兰的难民是如此。我们调查了这一印象是否由该议题在网络新闻和社交媒体中的反映所证实，从而将网络上的议题表征与其在社会中的感知联系起来。为此，我们结合并改编了前沿的自动文本处理技术，提出了一种新颖的多语言立场检测方法。从565家欧洲新闻媒体在2021年9月起的一年内发布的550万条Twitter帖子及回复开始，我们对欧洲及部分欧洲国家的移民相关媒体报道及相关的社交媒体互动进行了多语言分析。我们的分析结果表明，讨论确实存在重新框定，这通过术语变化得以说明，例如从“migrant”变为“refugee”，甚至经常用“real refugees”等短语来强调。然而，关于公众感知中的立场转变，情况比预期的更加多样化。所有分析案例都显示，在乌克兰战争爆发前后，存在明显的时间性立场转变。尽管如此，在这种转变的规模和稳定性上，存在明显的国家差异。
英文摘要：
The war in Ukraine seems to have positively changed the attitude toward the critical societal topic of migration in Europe -- at least towards refugees from Ukraine. We investigate whether this impression is substantiated by how the topic is reflected in online news and social media, thus linking the representation of the issue on the Web to its perception in society. For this purpose, we combine and adapt leading-edge automatic text processing for a novel multilingual stance detection approach. Starting from 5.5M Twitter posts published by 565 European news outlets in one year, beginning September 2021, plus replies, we perform a multilingual analysis of migration-related media coverage and associated social media interaction for Europe and selected European countries. The results of our analysis show that there is actually a reframing of the discussion illustrated by the terminology change, e.g., from "migrant" to "refugee", often even accentuated with phrases such as "real refugees". However, concerning a stance shift in public perception, the picture is more diverse than expected. All analyzed cases show a noticeable temporal stance shift around the start of the war in Ukraine. Still, there are apparent national differences in the size and stability of this shift.
