Emotional Chatting Machine: Emotional Conversation Generation with Internal and External Memory
Table 5: The percentage of responses in manual evaluation with the score of Content-Emotion. For instance, 2-1 means content score is 2 and emotion score is 1.
['Method (%)', '2-1', '1-1', '0-1', '2-0', '1-0', '0-0']
As we can see, 27.2% of the responses generated by ECM have a Content score of 2 and an Emotion score of 1, while only 22.8% for Emb and 9.0% for Seq2Seq. These indicate that ECM is better in generating high-quality responses in both content and emotion.
