Figure 2From: Question answering system using Q & A site corpus Query expansion and answer candidate evaluation Performance of proposed method. This figure shows the top-5 accuracies and MRR of the experiments of the candidate answer evaluation when the value of γ changed from 0 to 1. The top-5 accuracy was maximized to 0.59 when γ = 0.93 and the MRR was maximized to 0.461 when γ =0.98.Back to article page
