Abstract

We present HPD: Harry Potter Dialogue Dataset to facilitate the study of building dialogue agents for characters in a story. It differs from existing dialogue datasets in two aspects: 1) HPD provides rich background information about the novel Harry Potter, including scene, character attributes, and character relations; 2) All these background information will change as the story goes on. In other words, each dialogue session in HPD correlates to a different background, and the storyline determines how the background changes. We evaluate some baselines (e.g., GPT-2, BOB) on both automatic and human metrics to determine how well they can generate Harry Potter-like responses. Experimental results indicate that although the generated responses are fluent and relevant to the dialogue history, they are remained to sound out of character for Harry, indicating there is a large headroom for future studies. Our dataset is available.
