Hi, I’m currently looking for research/tools that give a complete (and fairly recent) overview about how much “sentiment” vocabulary is contained in *articles* of the English or any other Wikipedia. It could be just a simple matching of current sentiment dictionaries to article text. Just to get an idea how much (or better: little) vocabulary with a specific polarity Wikipedia contains recently and/or over time. Informal research welcome as well :)

I found some older papers (like [1]), but mostly also just for a smaller subset of articles. Mostly, sentiment analysis is (understandably) just a means to an end in papers, so they don’t provide a comprehensive overview of the whole article set.

Any pointers are appreciated.

Thanks, Fabian
