摘要:

在术语工作、自然语言处理和数字人文学中,一些研究致力于分析术语的上下文和含义的变化,以检测术语的语义变化和演变。我们区分了三种不同的方法来描述语境变化:基于模式和语言线索的分析方法,探索单个词的潜在语义空间的方法,以及主题成员关系的分析方法。本文提出了上下文波动的概念,作为一种新的检测语义变化的措施,并将其应用于政治科学的案例研究中的关键词提取。该措施量化了一个词的上下文变化的动态历时语料库中,以确定的时间段,其特点是激烈的争议性辩论或大量的语义转换。

英文摘要:

In terminology work, natural language processing, and digital humanities, several studies address the analysis of variations in context and meaning of terms in order to detect semantic change and the evolution of terms. We distinguish three different approaches to describe contextual variations: methods based on the analysis of patterns and linguistic clues, methods exploring the latent semantic space of single words, and methods for the analysis of topic membership. The paper presents the notion of context volatility as a new measure for detecting semantic change and applies it to key term extraction in a political science case study. The measure quantifies the dynamics of a term's contextual variation within a diachronic corpus to identify periods of time that are characterised by intense controversial debates or substantial semantic transformations.
