Measuring the Temporal Dimension of Text: An Application to Policymaker Speeches

Working Paper: CEPR ID: DP17931

Authors: David Byrne; Robert Goodhead; Michael McMahon; Conor Parle

Abstract: Discussions of time are central to many questions in the social sciences and to official announcements of policy. Despite the growing popularity of applying Natural Language Processing (NLP) techniques to social science research questions, before now there have been few attempts to measure expressions of time. This paper provides a methodology to measure the "third T of Text": the Time dimension. We also survey the techniques used to measure the other Ts, namely Topic and Tone. We document key stylised facts relating to temporal information in a corpus of policymaker speeches.
