Times Are Changing: Investigating the Pace of Language Change in Diachronic Word Embeddings

摘要

We propose Word Embedding Networks (WEN), a novel method that is able to learn word embeddings of individual data slices while simultaneously aligning and ordering them without feeding temporal information a priori to the model. This gives us the opportunity to analyse the dynamics in word embeddings on a large scale in a purely data-driven manner. In experiments on two different newspaper corpora, the New York Times (English) and Die Zeit (German), we were able to show that time actually determines the dynamics of semantic change. However, we find that the evolution does not happen uniformly, but instead we discover times of faster and times of slower change.
