Variation in Coreference Strategies across Genres and Production Media

1 code implementation • COLING 2020 • Berfin Akta{\c{s}}, Manfred Stede

In response to (i) inconclusive results in the literature as to the properties of coreference chains in written versus spoken language, and (ii) a general lack of work on automatic coreference resolution on both spoken language and social media, we undertake a corpus study involving the various genre sections of Ontonotes, the Switchboard corpus, and a corpus of Twitter conversations.

We confirm our hypothesis that discourse relations in written social media conversations are expressed differently than in (news) text.
