Method and apparatus for determining a dialog state, dialog system, computer device, and storage medium

A computer device, comprising:

• circuitry configured to:
• obtain first dialog information, the first dialog information being dialog information inputted during a dialog process;
• determine, based on the first dialog information, target scenario information corresponding to the first dialog information, the target scenario information being used to indicate a dialog scenario of the first dialog information;
• determine, based on a scenario vector of the target scenario information, at least one piece of candidate scenario information of a plurality of pieces of scenario information having an association relationship with the target scenario information;
• and
• obtain, based on the at least one piece of candidate scenario information and the target scenario information, a first dialog state according to the first dialog information, the first dialog state being used to represent a response mode for responding to the first dialog information, wherein
• the plurality of pieces scenario information is represented by a plurality of scenario vectors, each scenario vector representing an association relationship between the scenario information corresponding to the respective scenario vector and other scenario information of the plurality of pieces of scenario information,
• the plurality of scenario vectors is constructed according to at least one scenario network before the at least one piece of candidate scenario information is determined, the plurality of scenario vectors corresponding one-to-one to the plurality of pieces of scenario information, and
• the at least one scenario network is based on semantic tags of the plurality of pieces of scenario information, each semantic tag being a network node in the at least one scenario network and identifying a type of a dialog scenario indicated by the scenario information corresponding to the respective semantic tag.

A non-transitory computer-readable medium storing computer-readable instructions that, when executed by processing circuitry, cause the processing circuitry to perform a method comprising:

• obtaining first dialog information, the first dialog information being dialog information inputted during a dialog process;
• determining, based on the first dialog information, target scenario information corresponding to the first dialog information, the target scenario information being used for indicating a dialog scenario of the first dialog information;
• determining, based on a scenario vector of the target scenario information, at least one piece of candidate scenario information of a plurality of pieces of scenario information having an association relationship with the target scenario information;
• and
• obtaining, based on the at least one piece of candidate scenario information and the target scenario information, a first dialog state according to the first dialog information, the first dialog state being used for representing a response mode for responding to the first dialog information, wherein
• the plurality of pieces scenario information is represented by a plurality of scenario vectors, each scenario vector representing an association relationship between the scenario information corresponding to the respective scenario vector and other scenario information of the plurality of pieces of scenario information,
• the plurality of scenario vectors is constructed according to at least one scenario network before the at least one piece of candidate scenario information is determined, the plurality of scenario vectors corresponding one-to-one to the plurality of pieces of scenario information, and
• the at least one scenario network is based on semantic tags of the plurality of pieces of scenario information, each semantic tag being a network node in the at least one scenario network and identifying a type of a dialog scenario indicated by the scenario information corresponding to the respective semantic tag.
