Del Tredici Marco et al., « Tracing metaphors in time through self-distance in vector spaces », Accademia University Press, ID : 10.4000/books.aaccademia.1760
From a diachronic corpus of Italian, we build consecutive vector spaces in time and use them to compare a term’s cosine similarity to itself in different time spans. We assume that a drop in similarity might be related to the emergence of a metaphorical sense at a given time. Similarity-based observations are matched to the actual year when a figurative meaning was documented in a reference dictionary and through manual inspection of corpus occurrences.
