Speaker: Pierpaolo Basile

Abstract: During the last decade, the surge in available data spanning different epochs has inspired a new analysis of cultural, social, and linguistic phenomena from a temporal perspective.

In this talk, I will describe Temporal Random Indexing (TRI) a method that enables the analysis of the time evolution of the meaning of a word by exploiting large corpora. TRI is able to build WordSpaces that take into account temporal information. This methodology is exploited for building time series that trace how a word changes its meaning over time. I will report some experiments on the Italian language, and I will show the preliminary results obtained during my visiting at the Turing Institute by analysing the UK internet archive corpus.
