Abstract: Systems and methods for open domain question-answering are disclosed. In one embodiment, a method of providing answers to a question includes retrieving, by a computing device, a plurality of passages relevant to a search query generating a plurality of question-passage pairs, wherein each question-passage pair includes the search query and an individual passage of the plurality of passages, and determining, using a computer model, a probability that a passage of each question-passage pair of at least some of the plurality of question-passage pairs is an answer to a question posed by the search query. The method also includes displaying, on an electronic display, a selected passage of a question-passage pair having a highest probability that the passage is the answer to the question posed by the search query.
