Webinar content: 

Understanding the sentiment of a nation's population can provide valuable insights into societal well-being, political stability, economic trends and educational needs. Social media platforms offer a wealth of real-time data that can be analyzed to develop a national sentiment statistic. As such, it presents a lot of opportunities. However, there are also obstacles associated with using data science to automate national statistics based on social media.

In this presentation, we address these obstacles by discussing different topics related to the use of Twitter data to develop a national sentiment statistic for Flanders, Belgium, and the measure gross national happiness in different countries. We highlight the challenges associated with selection bias, annotator bias, and model performance. We then propose solutions to these challenges, including techniques for predicting annotation difficulty and correcting for selection bias.
