More recently, various other applications have been proposed to improve the existing HDP inference algorithms (Wang, Paisley, and Blei 2011;Bryant and Sudderth 2012).
because the number of event mentions in the ECB corpus is smaller than the number of mentions in the ACE corpus, the iFHMM-iHMM model utilizes a larger number of features values (0.91% of feature values selected for α ′ = 150) extracted from the new corpus in order to obtain most of its best results.
