This section compares the proposed system (called Global-RNN) with the state-of-the-art models on our four datasets. These systems include the neural network model in<cite> (Francis-Landau et al., 2016)</cite> , the joint model for entity analysis in (Durrett and Klein, 2014) and the AIDA-light system with two-stage mapping in (Nguyen et al., 2014b) 6 . Table 2 shows the performance of the systems on the test sets with the reference knowledge base of the June 2016 Wikipedia dump.
