Task-Oriented Dialog Systems that Consider Multiple Appropriate Responses under the Same Context
Table 5: Human evaluation results. Models with data augmentation are noted as (+). App denotes the average appropriateness score.
['Model', 'Diversity', 'App', 'Good%', 'OK%', 'Invalid%']
The results are shown in Table 5. [CONTINUE] We report the average value of diversity and appropriateness, and the percentage of responses scored for each appropriateness level. [CONTINUE] With data augmentation, our model obtains a significant improvement in diversity score and achieves the best average appropriateness score as well. [CONTINUE] However, the slightly increased invalid response percentage [CONTINUE] We also observe our DAMD model outperforms HDSA in both diversity and appropriateness scores.
