We provide a new executable file to download all collected data in HPD. See ALL_DATA Download for more details.
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.
Harry Potter Dialogue is the first dialogue dataset that integrates with scene, attributes and relations which are dynamically changed as the storyline goes on. Our work can facilitate research to construct more human-like conversational systems in practice. For example, virtual assistant, NPC in games, etc. Moreover, HPD can both support dialogue generation and retrieval tasks.
Formally, the task of aligning dialogue agents with characters in a storyline can be defined as follows: Given a dialogue history
The dialogue agent is supposed to generate a response
In this repository, we release Chinese and English versions of collected HPD. Notice that, due to the misalignment of English and Chinese story corpus, the collected data in English and Chinese may slightly differ.

Our datasets consist of the following parts:
- Dialogue: collected from Harry Potter Novel
- Scene: the text that surrounds and immediately relates to the dialogue is regarded as the scene.
-
Attributes: We collect 13 attributes of each character in total:
$\texttt{Gender}, \texttt{Age}, \texttt{Lineage}, \texttt{Talents}, \texttt{Looks} ,\texttt{Achievement}, \texttt{Title}, \texttt{Belongings}, \texttt{Export}, \texttt{Hobby}, \texttt{Character}, \texttt{Spells}, \texttt{Nickname}$ -
Relations: We collect 12 relations of each character with Harry:
$\texttt{Friend}, \texttt{Classmate}, \texttt{Teacher}, \texttt{Family}, \texttt{Lover}, \texttt{Opponent}, \texttt{Teammate}, \texttt{Enemy}$ , Harry's$\texttt{Familiarity}$ to someone, Harry's$\texttt{Affection}$ to someone, someone's$\texttt{Familiarity}$ to Harry, and someone's$\texttt{Affection}$ to Harry.
Our dataset are annotated by four professional annotaters (Harry Potter Fans), which is divided into four stages:
- Four annotaters are required to read the Harry Potter book first;
- Three of them are required to annotate correponding information;
- Another one is responsible for intergrating their annotations to get high agreement data;
- Last, we manually double-check and revise mistakes to further ensure the data quality.
Considering not all characters are essential to understanding and driving the story in Harry Potter series, we choose 113 important characters to annotate their attributes and relations, such as Harry, Ron and etc.
we request the annotators to extract all multi-turn dialogues from the books. Besides, the speaker name of each utterance in the session is labeled as well. As a result, we collect 1042 dialogue sessions as our training set.
HPD constructs a test set with 178 dialogue sessions to evaluate how similar a dialogue system is to Harry Potter. Each session in our test set consists of at least one positive response and 9 negative responses. This test set can facilitate the evaluation of both generation-based and retrieval-based dialogue systems.
We divide the attributes into two categories: (1) inborn; (2) nurture. The former denotes some innate attributes or abilities, which contains
The relations between Harry and other characters can be classified into binary relations and discrete relations. The former includes 8 types, which are
-
Affection: is rated on a twenty-level, ranging from -10 to 10, where 10 indicates the highest affection and -10 indicates the lowest affection. And
$\texttt{Score(Affection)>0}$ denotes the character has the positive relationship with Harry while$\texttt{Score(Affection)<0}$ means the character has the negative relationship with Harry. -
Familiarity: we also rate
$\texttt{Familiarity}$ with 10 level, which ranges from 0 to 10, where 10 indicates the highest affection and 0 indicates the lowest affection. Concretely,$\texttt{Score(Familiarity)=0}$ denotes stranger, and$\texttt{Score(Familiarity)=10}$ denotes two characters who are often stay together and very familiar with each other's habits, secrets and temperaments.
Detailed annotation steps and rules can be seen in our paper.
To avoid the potential issue of using Harry Potter Novels, we promise the annotated dataset is developed for non-commercial use. Moreover, we only provide the line number and page number of each collected dialogue in Harry Potter novel rather than give the detailed content of each dialogue session. We further supply the script to extract corresponding raw dialogue data from the novels according to the provided line and page numbers. As for the annotated character attributes and relations, we have our own copyright and release for research communities.
As for downloading our datasets, please refer to our new website HPDialogue.
We process our data in a unified format, and store in json files. The general format is:
{
"dialogue-xx":{
"Position": <Chapter-Scene>,
"Speakers": [speaker-1, ..., speaker-n],
"Scene": <context>,
"Dialogue": <dialogue context>,
"Positive-Response": <response text>,
"Negative- Response": [<negative_text_1>, ..., <negative_text_n>] (test set only)
"Attributes": {
"speaker-1": {
"name": <name_text>,
"nickname": <nickname_text>,
...
"Spells": <spells_text>
},
...
"speaker-n": {
"name": <name_text>,
"nickname": <nickname_text>,
...
"Spells": <spells_text>
}
}
"Relations With Harry": {
"speaker-1": {
"name": <name_text>,
"friend": <friend_score>,
...
"His familiarity with Harry": <familiarity_score>
},
...
"speaker-n": {
"name": <name_text>,
"friend": <friend_score>,
...
"His familiarity with Harry": <familiarity_score>
}
}
}
- dialogue-xx: Denotes the index of the dialogue in our dataset.
- Position: Denotes the timeline of the dialogue in the novel. "ChapterX-Y" refers to the dialogue occurs in the Y-th scene of X-th Chapter in the book.
- Speakers: Participants in the dualogue.
- Scene: Context of the dialogue.
- Dialogue: Dialogue history.
- Positive-Response: Human annotated response.
- Negative-Response: Negative responses generated by large pre-trained language models.
- Attributes: Character attributes.
- Relations: Character Relations With Harry.
Also, we can free to change our dataset into other formats, such as Personal-Dialogue Format. Notice that, sometimes "Relations With Harry" could be none if the dialogue speakers not in the annotated 113 important characters.
Morever, we provide HPD to download:
- All json-format files for training/evaluating.
- All annotated attributes and relations of 113 important characters stored in excel-format files.
- Raw novel corpus in Chinese and English. You can utilize them to pre-train your dialogue or text generative models (like GPT-2 in the paper), as well as post-train dialogue retrieval models.
Here we report automatic and huaman evaluations results of four baselines in our paper (only English at the time).
