News-sentiment Website
Through textual analysis of financial news, we assess the macroeconomic conditions. Using the content of 166,822 articles from Wind Financial News spanning from January 2013 to June 2021, we have developed a topic model. This model summarizes macroeconomic news into 80 intelligible topics, and quantifies the proportion of news attention allocated to each topic at each time point. Simultaneously, we provide a presentation of highly relevant vocabulary associated with each topic. Subsequently, we utilize our news attention estimates as input for a numerical economic time series statistical model, thereby obtaining higher-frequency macroeconomic data.
