Risk address identification method and apparatus, and electronic device

An electronic device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• acquire an address word sequence corresponding to an input address;
• determine an address word in the address word sequence, the determined address word matching a risk word corresponding to a risk address;
• generate an observation sequence corresponding to the address word sequence according to the determined address word;
• process the observation sequence 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
• identify whether the input address is a risk address by making a classification decision on the decision vector.

A computer-readable storage medium storing thereon a computer program that, when executed by a processor of a device, causes the device to perform a risk address identification method, the method comprising:

• 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 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.
