Event Coreference For Information Extraction
نویسندگان
چکیده
We propose a general approach for performing event coreference and for constructing complex event representations, such as those required for information extraction tasks. Our approach is based on a representation which allows a tight coupling between world or conceptual modelling and discourse modelling. The representation and the coreference mechanism are fully implemented within the LaSIE information extraction system where the mechanism is used for both object (noun phrase) and event coreference resolution. Indirect evaluation of the approach shows small, but signiicant beneet, for information extraction tasks.

SinoCoreferencer: An End-to-End Chinese Event Coreference Resolver
This paper describes the design, implementation, and evaluation of SinoCoreferencer, a publicly-available end-to-end ACE-style Chinese event coreference system that achieves state-of-the-art performance on the ACE 2005 corpus. SinoCoreferencer comprises eight information extraction system components, including those for entity extraction, entity coreference resolution, and event extraction. Its...
متن کاملEvent Coreference Resolution with Multi-Pass Sieves
Multi-pass sieve approaches have been successfully applied to entity coreference resolution and many other tasks in natural language processing (NLP), owing in part to the ease of designing high-precision rules for these tasks. However, the same is not true for event coreference resolution: typically lying towards the end of the standard information extraction pipeline, an event coreference res...
متن کاملCoreference based event-argument relation extraction on biomedical text
This paper presents a new approach to exploit coreference information for extracting event-argument (E-A) relations from biomedical documents. This approach has two advantages: (1) it can extract a large number of valuable E-A relations based on the concept of salience in discourse; (2) it enables us to identify E-A relations over sentence boundaries (cross-links) using transitivity of corefere...
متن کاملJoint Inference over a Lightly Supervised Information Extraction Pipeline: Towards Event Coreference Resolution for Resource-Scarce Languages
We address two key challenges in end-to-end event coreference resolution research: (1) the error propagation problem, where an event coreference resolver has to assume as input the noisy outputs produced by its upstream components in the standard information extraction (IE) pipeline; and (2) the data annotation bottleneck, where manually annotating data for all the components in the IE pipeline...
متن کاملIntegrating Coreference Resolution for BEL Statement Generation
We describe a pipeline system that automatically generates Biological Expression Language (BEL) statements from biomedical journal articles. The system incorporates existing systems for coreference resolution, event extraction, and BEL statement generation. While addressing the BEL track (Track 4) at BioCreative V (2015), we also investigate how incorporating coreference resolution might impact...
