Linguistics Speaker Series Talk: Rebecca Hwa (University of Pittsburgh)
Separating the Sheep from the Goats: On recognizing the Literal and Figurative Usages of Idioms
Typically, we think of idioms as colorful expressions whose literal interpretations don’t match their underlying meaning. However, many idiomatic expressions can be used either figuratively or literally, depending on their contexts. In this talk, we survey both supervised and unsupervised methods for training a classifier to automatically distinguish usages of idiomatic expressions. We will conclude with a discussion about some potential applications.
