Title: “What we Talk about When we Talk about Politics"
How does the meaning of words change over time? Methods in Natural Language Processing allow us to study the semantic shift of language elements, opening up a window onto language change. To this end, we curated a dataset of the Greek Parliament Proceedings that extends chronologically from 1989 up to 2020. It consists of more than 1 million speeches with extensive metadata, extracted from 5,355 parliamentary record files. The dataset can be used for both computational linguistics and political analysis-ideally, combining the two. We present such an application, showing (i) how the dataset can be used to study the change of word usage through time, (ii) between significant historical events and political parties, (iii) by evaluating and employing algorithms for detecting semantic shifts. The presentation is based on a paper that was accepted at the NeurIPS 2022 conference Track on Datasets and Benchmarks.
