Sentometrics is a portmanteau of sentiment and econometrics. The term is used to describe the econometric research that investigates the transformation of large volumes of qualitative sentiment data into quantitative sentiment variables, and their subsequent application in an econometric analysis of the relationships between sentiment and other variables.
Below we list some of our own contributions to the academic literature, together with the research papers that use our thematic indicator time series. We indeed welcome very much academic researchers to use our thematic indicator series free of charge. Feel free to contact us when interested, even for (ideas about) media-indicators that are currently not available on the public access API.
