Reinforced Multi-task Approach for Multi-hop Question Generation
Table 4: Human evaluation results for our proposed approach and the NQG model. Naturalness and difficulty are rated on a 1–5 scale and SF coverage is in percentage (%).
['Model', 'Naturalness', 'Difficulty', 'SF Coverage']
The proposed approach is able to generate better questions in terms of Difficulty, Naturalness and SF Coverage when compared to the NQG model.
