From Plots to Endings: A Reinforced Pointer Generator for Story Ending Generation
Table 3: Human Evaluation Results.
['[BOLD] Models', '[BOLD] Consistency', '[BOLD] Readability']
\deleted We randomly select 100 stories from test set and evaluate endings generated by different models. Apparently, PGN+Sem_L+RL and PGN+Sem_L achieve the best results in terms of consistency and readability respectively. The readability score of PGN+sem_L+RL is good enough, with the difference of 0.02 compared to the best result (PGN+Sem_L). We can also observe that readability scores of all the models are basically equivalent. It manifests that all the models have the ability to generate grammatically and lexically correct endings. Therefore, we only analyze the consistency scores as follows.
