To evaluate the tonality of the articles I used an algorithm that calculates the value based on the word choice. I used a ready implementation from aylien.com.

In order to make a categorisation in pro lockdown or against, suitable rules would be necessary. I have so far searched for keywords (covid, etc) and determined the tonality. From my point of view a simple combination of the two values does not give a clear indication if an article is pro or contra.

Do you have any ideas how such a rule could look like?
