摘要:

理解语料库中的观点差异是计算社会科学的一项基本任务。在本文中,我们提出了切片词嵌入关联测试(SWEAT),这是一种新颖的统计指标,用于计算主题词集在两种分布表示中的相对极化。为此,SWEAT使用了两个额外的词集,被认为具有相反的效价,代表两个不同的极点。我们验证了我们的方法,并说明了一个案例研究,以显示所引入的措施的实用性。

英文摘要:

Understanding differences of viewpoints across corpora is a fundamental task for computational social sciences. In this paper, we propose the Sliced Word Embedding Association Test (SWEAT), a novel statistical measure to compute the relative polarization of a topical wordset across two distributional representations. To this end, SWEAT uses two additional wordsets, deemed to have opposite valence, to represent two different poles. We validate our approach and illustrate a case study to show the usefulness of the introduced measure.
