The purpose of this study is to analyse COVID-19 related news published across different geographical places, in order to gain insights in reporting differences. We performed pooling of news articles based on information retrieval using TF-IDF score in a data processing step and topic modeling using LDA with combination of 1 to 6 ngrams. We used VADER sentiment analyzer to explore the differences in sentiments in news articles reported across different geographical places.
