A Two-Phase Approach Towards Identifying Argument Structure in Natural Language
Table 6: Mean SimScore for Wikipedia. T-S-WL: Two-Step Approach without any restriction for linear structures. Rest of the abbreviations as per Table 5.
['[BOLD] Nodes', '[BOLD] Arg.', '[BOLD] T-S-1', '[BOLD] T-S', '[BOLD] T-S-WL', '[BOLD] S-S']
Here we imposed an additional restriction for the structures to be linear. However, in the fifth column T-S-WL, we report the SimScore following the Two-Step approach without any restriction. We observe that the Single-Step approach performs relatively better for the Wikipedia dataset as compared to the Debatepedia dataset. We think this is due to the bigger arguments in Debatepedia.
