Dataset Card for Taskmaster-2

Dataset Summary

Taskmaster is dataset for goal oriented conversations. The Taskmaster-2 dataset consists of 17,289 dialogs in the seven domains which include restaurants, food ordering, movies, hotels, flights, music and sports. Unlike Taskmaster-1, which includes both written "self-dialogs" and spoken two-person dialogs, Taskmaster-2 consists entirely of spoken two-person dialogs. In addition, while Taskmaster-1 is almost exclusively task-based, Taskmaster-2 contains a good number of search- and recommendation-oriented dialogs. All dialogs in this release were created using a Wizard of Oz (WOz) methodology in which crowdsourced workers played the role of a 'user' and trained call center operators played the role of the 'assistant'. In this way, users were led to believe they were interacting with an automated system that “spoke” using text-to-speech (TTS) even though it was in fact a human behind the scenes. As a result, users could express themselves however they chose in the context of an automated interface.

Data Fields

Each conversation in the data file has the following structure:

• conversation_id: A universally unique identifier with the prefix 'dlg-'. The ID has no meaning.
• utterances: A list of utterances that make up the conversation.
• instruction_id: A reference to the file(s) containing the user (and, if applicable, agent) instructions for this conversation.

Each utterance has the following fields:

• index: A 0-based index indicating the order of the utterances in the conversation.
• speaker: Either USER or ASSISTANT, indicating which role generated this utterance.
• text: The raw text of the utterance. In case of self dialogs (one_person_dialogs), this is written by the crowdsourced worker. In case of the WOz dialogs, 'ASSISTANT' turns are written and 'USER' turns are transcribed from the spoken recordings of crowdsourced workers.
• segments: A list of various text spans with semantic annotations.

Each segment has the following fields:

• start_index: The position of the start of the annotation in the utterance text.
• end_index: The position of the end of the annotation in the utterance text.
• text: The raw text that has been annotated.
• annotations: A list of annotation details for this segment.

Each annotation has a single field:

• name: The annotation name.
