Table 5: Ablation Study on Representation Modules.
['Method', 'TNT', 'BTC']
Ablation Study. The first (referred as “– language model”) excludes the contextualized character representation module from Neural-Char-CRF, the second (referred as “– string match”) replaces the proposed two modules with static character embedding. The results demonstrate the effectiveness of both proposed representation modules – significant performance improvements can be observed by adapting either of these two approaches.
