Sentiment and emotion

Within the sentiments dataset, the lexicon nrc contains a dictionary of words and an emotion associated with that word. Emotions such as joy, trust, anticipation, and others are found within this dataset.

In the Russian tweet bot dataset you have been exploring, you have looked at tweets sent out by both a left- and a right-leaning tweet bot. Explore the contents of the tweets sent by the left-leaning (democratic) tweet bot by using the nrc lexicon. The left tweets, left, have been tokenized into words, with stop-words removed.
