This is a Twitter wordcloud, constructed daily, using the phrase “climate change”. The most recent 500 tweets from the time of the run (2pm) that contain the phrase “climate change” are organized in a corpus and then a term document sparse matrix.
We then determine word frequency counts and display that in the form of a word cloud – on a daily basis. We take into account the geographic location of the tweets by selecting a radius of 100 miles around the University of Idaho, in Moscow, ID.
