Several weeks ago, I posted an analysis of tweets about the restrictions imposed on Melbourne residents in an effort to control an outbreak of Covid-19. That analysis was essentially a road-test of a Knime workflow that I had been piecing together for some time, but that was not quite ready to share. Since writing that post, I have revised and tidied up the workflow so that anyone can use it, and I have made it available on the Knime Hub.
In the present post, I provide a thorough description of the workflow, which I have named the TweetKollidR, and demonstrate its use through a case study of yet another dataset of tweets about Melbourne’s lockdown (which, as I write this, still has not ended, although it has been eased). 1
