Reading the Manual: Event Extraction as Definition Comprehension
Yunmo Chen, Tongfei Chen, Seth Ebner, Aaron Steven White, Benjamin Van Durme · 2020
We ask whether text understanding has progressed to where we may extract event information through incremental refinement of bleached statements derived from annotation manuals.Such a capability would allow for the trivial construction and extension of an extraction framework by intended end-users through declarations such as, Some person was born in some location at some time.We introduce an example of a model that employs such statements, with experiments illustrating we can extract events under closed ontologies and generalize to unseen event types simply by reading new definitions.
