Abstract
An information retrieval method includes obtaining Mi (i+1)th-hop candidate documents based on a retrieval text query and Ki ith-hop candidate documents; obtaining a score of each candidate document in the Mi (i+1)th-hop candidate documents; obtaining, based on a score of a candidate document Pjy(i+1) and a probability of a path L, a probability of a path corresponding to the candidate document Pjy(i+1); obtaining K(i+1) (i+1)th-hop candidate documents based on probabilities of paths respectively corresponding to the Mi (i+1)th-hop candidate documents; and obtaining, based on the K(i+1) (i+1)th-hop candidate documents, a retrieval result corresponding to the query.
