I was looking for a source where there would be an extended amount of texts with aggressive tone. It can be intertwined with non-aggressive texts, but it would be good if the ratio of aggressive texts to non-aggressive texts be no less then 1:5.
I was thinking about discussion forums which would be discussing the immigrants issue with contributors of lesser mind who would be very hateful and xenofobic. Or supporters of extreme political parties.
The content being spoken about is not really important, the more diverse it would be the better.
In the past I was looking for a less specific sentiment like "like/dislike" something for which reviews of movies on IMDB were an ideal source and I had some good results.
However it is very difficult to find a base of data with aggressive sentiment or at least some good internet sources from which the data could be gathered.
Do you have any ideas on how I could gather up such data?
