Question and answer method and device, electronic equipment and readable storage medium

The invention provides a question and answer method and device, electronic equipment and a readable storage medium, and relates to the technical field of artificial intelligence such as natural language processing, deep learning and cloud service. The question and answer method comprises the steps of obtaining a to-be-queried question, and obtaining a first question vector and a second question vector of the to-be-queried question; determining at least one first target vector from a plurality of candidate vectors according to the first problem vector; obtaining a first picture vector corresponding to the at least one first target vector according to a picture corresponding to the at least one first target vector; determining at least one second target vector from the at least one first target vector according to the second problem vector and at least one first picture vector; and obtaining an answer to the to-be-queried question according to the candidate content corresponding to the at least one second targe
