CRAC: NAACL Workshop on Computational Models of Reference, Anaphora, and Coreference - June 6th, 2018, New Orleans

Workshop description

Background There has been a lot of research activity in anaphora / coreference resolution in recent years, but once the DAARC series ended, there were no events in Computational Linguistics entirely dedicated to this type of work. The Coreference Beyond Ontonotes (CORBON) workshops held in 2016 (with NAACL) and 2017 (with EACL) partially addressed this need, but their focus was primarily on under-investigated coreference phenomena. The CRAC series of workshops is intended to be an event of interest to the entire anaphora / coreference / reference community.

Objectives The aim of the proposed workshop(s) is to provide a forum where work on all aspects of computational work on anaphora resolution and annotation, including both coreference and types of anaphora such as bridging references resolution and discourse deixis, can be presented. We also intend to attract work on reference (e.g., deictical reference to objects displayed in a multimodal interface).

Important dates

The important dates for CRAC are the same as for every other NAACL 2018 workhop:

Deadline for submissions: Extended to 9 March 2018 (11:59pm Hawaii Standard Time)
Notification of acceptance: 2 April 2018
Camera-ready version due: 16 April 2018
Workshop date: 6th June 2018

Shared Task

The proposed (series of( workshop(s) will be accompanied, like CORBON, by a shared task. The shared task(s) in 2018 will be on anaphora resolution using ARRAU (Uryupina et al, to appear), a corpus designed to

cover a more diverse range of genres than typical coreference corpora, including news, task-oriented dialogue, and narrative;
provide annotations for all noun phrases, including non-referring NPs and singletons (unlike in OntoNotes where only coreferential mentions are an- notated) and carefully annotated their boundaries catering also for non- continuous mentions;
include annotation of the full range of anaphoric phenomena, including bridging and discourse deixis;
include the annotation of a variety of morpho-syntactic and semantic attributes of mentions, including genericity.

For more details, see the shared task page .
