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.

Bio: Pierpaolo Basile is an Assistant Professor at the Department of Computer Science, University of Bari Aldo Moro, Italy. He received the PhD in Computer Science from the University of Bari in 2009 with the dissertation "Word Sense Disambiguation for Intelligent Information Access".

His research interests include natural language processing, machine learning and information retrieval. He is the principal investigator of the project "Multilingual Entity Linking" funded by the Apulia regional program Future In Research.
