Question and answer processing method and device based on artificial intelligence, apparatus and storage medium

The invention provides a question and answer processing method and device based on artificial intelligence, an electronic apparatus and a storage medium. The method comprises the steps of encoding thequestion information and the document information through an encoding model in a question and answer processing model, and obtaining the encoding information corresponding to the question informationand the encoding information corresponding to the document information; establishing the directed graphs for the encoded information of the question information and the encoded information of the document information through an inference model in the question-answer processing model to obtain a directed graph including the question information and the document information; performing numerical inference processing on the directed graph including the problem information and the document information through the inference model to obtain the document information including a numerical relationship; and through a prediction model in the question and answer processing model, predicting the document information containing the numerical relationship to obtain an answer corresponding to the question information. Through the present invention, the accurate answers can be obtained according to the questions needing numerical inference.
