Selecting Topics, Validity and Sensitivity in Computational Communication Science

Let's dive into a CCS study, together with Waqas Ejaz. In this episode, hosted by Valerie Hase, Waqas tells us about why and how he used topic modeling (LDA) for analyzing news coverage on climate change in a low-income country such as Pakistan. In that, and apart from data access, Waqas and Valerie discuss the sensitive decision of the appropriate number of topics in topic modeling. Ejaz, W., Ittefaq, M. and Jamil, S. (2023).
