INFORMATION RETRIEVAL METHOD AND RELATED SYSTEM, AND STORAGE MEDIUM

Provided in the embodiments of the present application are an information retrieval method and a related system, and a storage medium. The method comprises: S1, obtaining Mi candidate documents of an (i+1)-th skip according to retrieval text Query and Ki candidate documents of an i-th skip; S2, acquiring a score of each candidate document in the Mi candidate documents of the (i+1)-th skip; S3, according to the score of a candidate document Pjy(i+1) and the probability of a path L, obtaining the probability of a path corresponding to the candidate document Pjy(i+1); S4, according to the probabilities of paths corresponding to the Mi candidate documents of the (i+1)-th skip, obtaining K(i+1) candidate documents of the (i+1)-th skip; and according to the K(i+1) candidate documents of the (i+1)-th skip, obtaining a retrieval result corresponding to the Query. By means of the present solution, sorting can be performed from a global optimum perspective of a global retrieval path, such that the accuracy and efficien
