Question and answer type paper retrieval method

The invention relates to a question and answer type paper retrieval method, and belongs to the technical field of paper retrieval. The question and answer type paper retrieval method comprises the steps that a question to be retrieved is input into a question and answer model, and a processing function matched with the question to be retrieved is determined; according to a processing function matched with the to-be-retrieved question, determining a function parameter matched with the keyword of the to-be-retrieved question; generating a retrieval result based on the processing function and the function parameter; the question and answer model is obtained by training through the following steps that a function set is constructed, wherein the function set comprises processing functions of questions in the thesis field and function parameters corresponding to the processing functions; constructing an initial problem set for the processing functions according to different combinations of parameters in the process
