ASU at TextGraphs 2019 Shared Task: Explanation ReGeneration using Language Models and Iterative Re-Ranking
Table 4: MAP for different Explanation Roles for BERT trained with classification head and context, before and after re-ranking till N=15
['Explanation Roles', 'BERT', '[ITALIC] N=15']
It can be seen that Iterative re-ranking improves MAP for Central and Grounding explanations but penalizes Lexical Glue.
