Accommodation Search Dialog Corpus (in Japanese)

Creative Commons Attribution 4.0 International License Python Versions CI Typos

Main part: data/main

The main part of this corpus consists of 210 Japanese dialogs between two people acting as a customer and an operator in a fictitious accommodation consultation service by using Slack. In a dialog, the customer informed the operator of their situation and needs. Then based on the information, the operator conducted a search to meet the customer's request. The dialog was finished once the operator judged that the requirements were specific enough to narrow appropriate accommodations. Dialogs are in two formats.

  • Text: data/main/dialog/text/*.tsv
  • JSON: data/main/dialog/json/*.json

Please read documents for more details.
