UTD-SpRL: A Joint Approach to Spatial Role Labeling
2012
International Workshop on Semantic Evaluation
We present a joint approach for recognizing spatial roles in SemEval-2012 Task 3. Candidate spatial relations, in the form of triples, are heuristically extracted from sentences with high recall. The joint classification of spatial roles is then cast as a binary classification over the candidates. This joint approach allows for a rich feature set based on the complete relation instead of individual relation arguments. Our best official submission achieves an F 1measure of 0.573 on relation
