NL Seminar- Smatch: an Evaluation Metric for Semantic Feature Structures

When:: Friday, December 7, 2012, 03:00 pm - 4:00 pm
Where:: 11th Floor Conf. Room (#1135)
Speaker:: Shu Cai
Description:: Abstract: Feature structures are useful for capturing logical semantic relationships. In this talk, we present smatch, a metric that determines semantic overlap between two semantic feature structures. We give an ef.cient algorithm to compute the metric, and we show the results of an inter-annotator agreement study.
