The 2nd Workshop on Computational Models of Reference, Anaphora and Coreference (CRAC 2019) (https://sites.google.com/view/crac2019)

6 or 7 June 2019 Minneapolis, MN, USA Collocated with NAACL 2019


The aim of the proposed workshop 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.

A special theme of the 2019 edition of the workshop is the Universal Coreference framework - a unified markup scheme applicable to multiple languages, reflecting common cross-linguistic understanding of reference-related phenomena. This theme was motivated by the recent successes of the development of Universal Dependencies. As with Universal Dependencies, the Universal Coreference framework aims to facilitate referential analysis of similarities and idiosyncracies among typologically different languages, support comparative evaluation of coreference resolution systems and enable comparative linguistic studies. The workshop organizers will develop and implement an initial version of the framework and organize a shared task around it as part of CRAC 2019. In addition, the workshop will include a panel discussion on possible improvements of the initial framework based on the outcomes of the shared task.


The workshop will welcome submissions describing both theoretical and applied computational work on anaphora / coreference resolution, including on languages other than English, and less-researched types of anaphora such as bridging references.

Topics of interest include but are not limited to the following:

- Coreference resolution for less-researched languages - Annotation and interpretation of anaphoric relations, including relations

other than identity coreference (e.g., bridging references, reference

to abstract entities) - Investigation of difficult cases of anaphora / coreference and their

resolution - Anaphora / coreference resolution in noisy data (e.g. in speech, social

media) - New applications of coreference resolution - Universal Coreference


Currently referential relations are most frequently analyzed in isolation with each language or annotation project proposing its own annotation model, usually incompatible with existing ones. With many incompatible schemata available it is difficult to compare quality of tools available for different languages, develop and maintain multilingual systems and perform cross-lingual analyses. Previous attempts of annotation uniformization (e.g. based on OntoNotes corpus) were hardly adopted, most likely due to complexity of the model and resulting portability issues. In light of this problem, the workshop will feature a panel organized around an initial Universal Coreference framework developed by the workshop organizers. Specifically, it will focus on the prospects of cross-lingual decoding of Universal Coreference in a set of corpora in various languages, featuring uniform annotation of nominal direct coreference. The proposed framework is intended to provide much wider coverage of languages than previous tasks on multilingual coreference resolution such as CoNLL-2012 Shared Task on Modeling Multilingual Unrestricted Coreference in OntoNotes without the restriction of having parallel data. The framework can be extended in a systematic manner, by releasing new language corpora and new versions of annotation guidelines. At the same time it does not prohibit language-specific extensions built on top of the common layer.
