Response Generation by Context-aware Prototype Editing

Understand

Open domain response generation has achieved remarkable progress in recent years, but sometimes yields short and uninformative responses.

• We propose a new paradigm for response generation, that is response generation by editing, which significantly increases the diversity and informativeness of the generation results.
• Our assumption is that a plausible response can be generated by slightly revising an existing response prototype.
• The prototype is retrieved from a pre-defined index and provides a good start-point for generation because it is grammatical and informative.
