| ### Dataset Summary | |
| CoQA is a large-scale dataset for building Conversational Question Answering systems. | |
| Our dataset contains 127k questions with answers, obtained from 8k conversations about text passages from seven diverse domains. The questions are conversational, and the answers are free-form text with their corresponding evidence highlighted in the passage. | |
| ### Supported Tasks and Leaderboards | |

| ### Data Fields | |
| The data fields are the same among all splits. | |
| #### default | |
| - `source`: a `string` feature. | |
| - `story`: a `string` feature. | |
| - `questions`: a `list` of `string` features. | |
| - `answers`: a dictionary feature containing: | |
| - `input_text`: a `string` feature. | |
| - `answer_start`: a `int32` feature. | |
| - `answer_end`: a `int32` feature. | |
