Tracing semantic change with distributional methods

This paper uses the tools of distributional semantics to investigate the semantic change of algo from a noun meaning ‘goods, possessions’ and an indefinite pronoun ‘something’ in the Medieval/Classical period of Spanish to an indefinite pronoun and degree adverb ‘a bit’ in contemporary Spanish. We compare the results of a previous corpus-based study (Amaral 2016) on the semantic change of algo with an analysis using word embeddings models with two goals: (i) to show how word embeddings can help identify different synchronic values of a word, and (ii) to provide measures of change through distributional semantic methods. We discuss the challenges of a study with this methodology using limited data from older periods of a language, hence putting into focus decisions that have to be made and their implications for the analysis. In this way, we hope to contribute to a fruitful integration of more traditional studies in diachronic semantics with the methodology of word embeddings.
