Extracting Social Meaning and Sentiment

Room: UTC 4.104

Description

The course will review central results from linguistics and cognitive psychology concerning the dimensions of affectivity and the ways in which attitudinal and emotional information is expressed in language. It will then focus on the computational extraction of such information from textual data using supervised and unsupervised methods. Special emphasis will be placed on bringing social and contextual information into the models and designing features that capture non-literal uses of language.
