Abstract
Embodiments of the specification disclose a risk address identification method and apparatus, and an electronic device. The risk address identification method includes: acquiring an address word sequence corresponding to an input address; determining an address word in the address word sequence, the determined address word matching a risk word corresponding to a risk address; generating an observation sequence corresponding to the address word sequence according to the determined address word; processing the observation sequence using a hidden Markov model obtained based on semantics learning before and after address words, to obtain a decision vector, wherein the decision vector represents probabilities of the risk address being matched by address words contained in the address word sequence; and identifying whether the input address is a risk address by making a classification decision on the decision vector.
