Despite its importance, prior work on event causality extraction in context in the NLP litera- ture is relatively sparse. In (Girju, 2003), the au- thor used noun-verb-noun lexico-syntactic patterns to learn that “mosquitoes cause malaria”, where the cause and effect mentions are nominals and not nec- essarily event evoking words. In (Sun et al., 2007), the authors focused on detecting causality between search query pairs in temporal query logs. (Beamer and Girju, 2009) tried to detect causal relations be- tween verbs in a corpus of screen plays, but limited themselves to consecutive, or adjacent verb pairs. In (Riaz and Girju, 2010), the authors first cluster sentences into topic-specific scenarios, and then fo- cus on.
