Séminaire - Optimizing the design of textual indices using sentometrics: Methodology and applications, Kris Boudt (VUB)

DeFiPP Seminar

Abstract: Textual sentiment analysis requires to select relevant texts and design weighting schemes to aggregate the intra-textual, across-text and across-time polarity expressed in textual communications. The selection and weighting decisions need to be optimized for the intended use case and account for the underlying data features like impression management by the author and the non i.i.d. nature of the textual data. The seminar will combine an overview of methodology together with applications to CEO letters and media articles. There is also a case study on constructing an Economic Policy Uncertainty index for Belgium.
