In this study, we outlined the field\u2019s terminology, describe existing metrics, their differences and shortcomings, as well as the available corpora and external resources. We analyzed existing state-of-the-art models and approaches, and reviewed recent advances and trends in the field, namely end-to-end systems that jointly model different subtasks of coreference resolution, and cross-lingual systems that aim to overcome the challenges of less-resourced languages. Finally, we discussed the main challenges and open issues faced by coreference resolution systems.<\/jats:p>","DOI":"10.3390\/info11020074","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T01:25:51Z","timestamp":1580693151000},"page":"74","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Coreference Resolution: Toward End-to-End and Cross-Lingual Systems"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3334-2838","authenticated-orcid":false,"given":"Andr\u00e9","family":"Ferreira Cruz","sequence":"first","affiliation":[{"name":"LIACC\/DEI, Faculdade de Engenharia, Universidade do Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8252-7292","authenticated-orcid":false,"given":"Gil","family":"Rocha","sequence":"additional","affiliation":[{"name":"LIACC\/DEI, Faculdade de Engenharia, Universidade do Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1252-7515","authenticated-orcid":false,"given":"Henrique","family":"Lopes Cardoso","sequence":"additional","affiliation":[{"name":"LIACC\/DEI, Faculdade de Engenharia, Universidade do Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"847","DOI":"10.1162\/COLI_a_00151","article-title":"A Constraint-Based Hypergraph Partitioning Approach to Coreference Resolution","volume":"39","author":"Sapena","year":"2013","journal-title":"Comput.
