Hannah Yan Han is doing #100dayprojects on data science and visual storytelling and I can only recommend that you take a look yourself. Below you find her R text analysis (#41) of UNHCR speeches and TV coverage on refugees.

Unsurprisingly, nouns like asylum, repatriation, displacement, persecution, plight, and crisis appear significantly more often in UNHCR speeches on refugees than in general English texts. The first visualization below shows the action-oriented verbs most commonly used in combination with these nouns.

This second visualization shows the most occurring verb-noun pairs.

Hannah used newsflash to retrieve the GDELT data on US TV news. Some channels seem to cover refugees more than others. I would have loved to see which topics occurred on each channel, but unfortunately she did not report on this.
