Query: TopiOCQA: Open-domain Conversational Question Answering with Topic
  Switching   In a conversational question answering scenario, a questioner seeks to
extract information about a topic through a series of interdependent questions
and answers. As the conversation progresses, they may switch to related topics,
a phenomenon commonly observed in information-seeking search sessions. However,
current datasets for conversational question answering are limiting in two
ways: 1) they do not contain topic switches; and 2) they assume the reference
text for the conversation is given, i.e., the setting is not open-domain. We
introduce TopiOCQA (pronounced Tapioca), an open-domain conversational dataset
with topic switches on Wikipedia. TopiOCQA contains 3,920 conversations with
information-seeking questions and free-form answers. On average, a conversation
in our dataset spans 13 question-answer turns and involves four topics
(documents). TopiOCQA poses a challenging test-bed for models, where efficient
retrieval is required on multiple turns of the same conversation, in
conjunction with constructing valid responses using conversational history. We
evaluate several baselines, by combining state-of-the-art document retrieval
methods with neural reader models. Our best model achieves F1 of 55.8, falling
short of human performance by 14.2 points, indicating the difficulty of our
dataset. Our dataset and code is available at
