Lee et al. (2012)
From Lee et al. (2012): "limited work that incorporates event-related information in entity coreference, typically by incorporating the verbs in context as features. For instance, Haghighi and Klein (2010) include the governor of the head of nominal mentions as features in their model. Rahman and Ng (2011) also used event-related information by looking at which semantic role the entity mentions can have and the verb pairs of their predicates.
Humphreys et al. (1997) considered entities as well as events, but due to the lack of a corpus annotated with event coreference, their approach was only evaluated implicitly in the MUC-6 template filling task. To our knowledge, the only previous work that considered entity and event coreference resolution jointly is He (2007), but limited to the medical domain and focused on just five semantic categories."
Lee et al. (2012) extended the ECB corpus with entity coreference information. The resulting corpus can be downloaded at: http://nlp.stanford.edu/pubs/jcoref-corpus.zip. It is sometimes referred to as "ECB 0.1" (Cybulska and Vossen, 2014, p. 4549).
