Related paper for Jan 27

This week I read a paper - Catching Metaphors (Matt Gedigian, John Bryant, Srini Narayanan, Branimir Ciric).

It tries to classify whether a particular occurrence is a literal or metaphorical using a maxent classifier. The paper restricts the problem to identifying the metaphorical nature to verbs. It works on an corpus annotated by Propnet. The feature set is the bias of the verb (percentage of occurrences of metaphor to literal), and the type of the arguments of the annotation. Based on crossvalidation, the authors claim an accuracy of 96.98%.
