Modeling Document-level Causal Structures for Event Causal Relation Identification

NAACL 2019 Lei GaoPrafulla Kumar ChoubeyRuihong Huang

We aim to comprehensively identify all the event causal relations in a document, both within a sentence and across sentences, which is important for reconstructing pivotal event structures. The challenges we identified are two: 1) event causal relations are sparse among all possible event pairs in a document, in addition, 2) few causal relations are explicitly stated... (read more)
