### Dataset Summary
CoQAR is a corpus containing 4.5K conversations from the open-source dataset [Conversational Question-Answering dataset CoQA](https://stanfordnlp.github.io/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.
### Languages
English.
## Dataset Structure
The dataset is composed of several conversations. Each row correspond to one question of one conversation. The fields are the following:
- conversation_id
- turn_id: first question has turn id 0, second question has turn id 1, etc.
- original_question: string
- 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,
- file_name
- story: string providing context for the conversation, from which the answers can be deduced
- name
