But as the goal of this study is to leverage discourse level topic structure in a document for improving event coreference resolution performance, we only evaluate the ILP system using regular documents (news articles) in the KBP corpora.
we train our event extraction system and local coreference resolution classifier on 310 documents from the KBP 2015 corpus that consists of both discussion forum documents and news articles, tune the hyper-parameters corresponding to ILP using 50 news articles 6 from the KBP 2015 corpus and evaluate our system on 4 The ECB+ (Cybulska and Vossen, 2014) corpus is another commonly used dataset for evaluating event coreference resolution performance.
