DailyDialog: A Manually Labelled Multi-turn Dialogue Dataset

We develop a high-quality multi-turn dialog dataset, DailyDialog, which is intriguing in several aspects. The language is human-written and less noisy. The dialogues in the dataset reflect our daily communication way and cover various topics about our daily life. We also manually label the developed dataset with communication intention and emotion information. Then, we evaluate existing approaches on DailyDialog dataset and hope it benefit the research field of dialog systems.

[New!] The dataset file (.zip) has been updated on Nov 1, 2017 to fix a segmentation bug in train.zip. Thank Sanghoon from KAIST to report this bug!

Basic Statistics

Th developed DailyDialog dataset contains 13,118 multi-turn dialogues. We also count the average speaker turns and tokens to give a brief view of the dataset. The resulting statistics are given in the table below. From the statistics we can see, the speaker turns are roughly 8, and the average tokens per utterance is about 15.

Total Dialogues 13,118
Average Speaker Turns Per Dialogue 7.9
Average Tokens Per Dialogue 114.7
Average Tokens Per Utterance 14.6


The words in Italic are speaker B’s own ideas that are new for the other speaker A. The underlined words in purple explicitly indicate the emotions. In the fourth speaker turn, speaker B first expresses his/her feeling on what he/she has heared from speaker A, which reveals his/her understanding. Then, speaker B suggests by saying “Just breathe deeply when you feel yourself getting upset”. Following the direct response towards A, B’s suggestion is original yet context-dependent. It shows that B builds up a connection link by responding to forgoing context and proposing new suggestions.
