论文摘要
语言正在不断发生变化，而这些变化的基础的机制仍然是辩论的问题。在这项工作中，我们通过因果关系来实现语言进化，以便不仅建模各种分布因素如何与语言变化相关，而且对它们的因果关系如何影响。特别是，我们研究语，这是一种非正式语言，通常仅限于特定的群体或社会环境。我们分析语词的语义变化和频移，并将其与标准的，nonslang单词进行比较。利用因果发现和因果推理技术，我们衡量了单词类型（语/nonslang）对语义变化和频移的影响，及其与频率，多义和语音的一部分的关系。我们的分析在对语言变化的研究中提供了一些新的见解，例如，我们表明语单词经历了较少的语义变化，但随着时间的流逝往往会有较大的频率变化。
Languages are continuously undergoing changes, and the mechanisms that underlie these changes are still a matter of debate. In this work, we approach language evolution through the lens of causality in order to model not only how various distributional factors associate with language change, but how they causally affect it. In particular, we study slang, which is an informal language that is typically restricted to a specific group or social setting. We analyze the semantic change and frequency shift of slang words and compare them to those of standard, nonslang words. With causal discovery and causal inference techniques, we measure the effect that word type (slang/nonslang) has on both semantic change and frequency shift, as well as its relationship to frequency, polysemy and part of speech. Our analysis provides some new insights in the study of language change, e.g., we show that slang words undergo less semantic change but tend to have larger frequency shifts over time.
