Abstract

We describe statistical models for detecting causality between two events. Our models are kinds of latent variable models, actually expanded versions of the existing statistical co-occurrence models. The (statistical) dependency information between two events needs to be incorporated into causal models. We handle this information via latent variables in our models. Through experiments, we achieved .678 F-measure value for the evaluation data.

Keywords

Causal Relation Causal Model Unlabeled Data Latent Variable Model Event Pair 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
