Dataset Summary
CoQAR is a corpus containing 4.5K conversations from the open-source dataset Conversational Question-Answering dataset CoQA, for a total of 53K follow-up question-answer pairs. In CoQAR each original question was manually annotated with at least 2 at most 3 out-of-context rewritings. COQAR can be used for (at least) three NLP tasks: question paraphrasing, question rewriting and conversational question answering.
We annotated each original question of CoQA with at least 2 at most 3 out-of-context rewritings.

- question_paraphrases : list of decontextualized rewrittings of the original question,
- answer: string, answer to the question,
- answer_span_start: start of the answer span (char number in the story),
- answer_span_end: end of the answer span (char number in the story),
- answer_span_text: string, excerpt of the story from answer_span_start to answer_span_end,
- conversation_history: list of strings corresponding to previous (original) questions and answers,
