ALCIDE: co-occurrences and polarity of words

Our group is using the 3D library to graphically visualize co-occurrence networks within ALCIDE. The idea is to combine co-occurrences together with information about polarity of words involved in the network.

For Kennedy’s and Nixon’s speeches we have used SentiWords, a resource provided by FBK containing 155,000 words associated with a sentiment score.
