摘要:

我们提出了随时间推移的意义聚类(SCoT),一种新的基于网络的工具,用于分析词汇变化。SCoT将单词的含义表示为相似单词的聚类。它将它们的形成、变化和消亡可视化。有两种主要的方法来探索动态网络:离散的比较一系列聚类图从不同的时间点。连续网络分析一个动态网络在一段时间内的变化。SCoT提供了一种新的混合解决方案。首先,它将带时间戳的文档聚合到间隔中,并在每个离散间隔中计算一个感测图。然后,它合并的静态图到一个新的类型的动态语义邻域图随着时间的推移。由此产生的意义集群提供了独特的详细的见解,在连续的时间间隔与模型的透明度和出处的词汇变化。SCoT已成功地用于一项关于“危机”含义变化的欧洲研究。

英文摘要:

We present Sense Clustering over Time (SCoT), a novel network-based tool for analysing lexical change. SCoT represents the meanings of a word as clusters of similar words. It visualises their formation, change, and demise. There are two main approaches to the exploration of dynamic networks: the discrete one compares a series of clustered graphs from separate points in time. The continuous one analyses the changes of one dynamic network over a time-span. SCoT offers a new hybrid solution. First, it aggregates time-stamped documents into intervals and calculates one sense graph per discrete interval. Then, it merges the static graphs to a new type of dynamic semantic neighbourhood graph over time. The resulting sense clusters offer uniquely detailed insights into lexical change over continuous intervals with model transparency and provenance. SCoT has been successfully used in a European study on the changing meaning of `crisis'.
