Liuliu writeup of Cohn 2005

This is a review of Cohn_2005_semantic_role_labelling_with_tree_conditional_random_fields by user:Liuliu.

This paper is about using Conditional random fields to do semantic role labeling. By using CRF, they make use of the tree structure of a sentence derived from the parsing tree instead of a linear chain, and also they model the interaction between parents and children with pairwise features. Maybe because this is a short paper, authors didn't give more detailed analysis of evaluation results.
