We are excited to announce that our short paper "Modeling the Evolution of Word Senses with Force-Directed Layouts of Co-occurrence Networks" has been accepted for presentation at the LChange Workshop, which is co-located with ACL 2021. This paper is based on preliminary work of Robert Schwanhold for his Master's thesis.


Languages evolve over time and the meaning of words can shift. Furthermore, individual words can have multiple senses. However, existing language models typically only reflect one word sense per word and don't deal with semantic changes over time. While there are language models that can either model semantic change of words or multiple word senses, none of them cover both aspects simultaneously. We propose a novel force-directed graph layout algorithm to draw a network of frequently co-occurring words. In this way, we are able to use the drawn graph to visualize the evolution of word senses. In addition, we hope that jointly modeling semantic change and multiple senses of words results in improvements for the individual tasks.
