- the user's behavior record characteristics include access records, and/or function usage records of all products within the scope of the customer service center consulting service within a predetermined time period. For example, it can be which pages are opened in an App (application) in the past 72 hours, which function operations are performed, and the like.
- the user's behavior record characteristics reflect the user's use of the product being consulted in a short period of time; if a user frequently uses the customer service function during that time period and queries the same knowledge point, the user is likely to encounter a robot customer service solution. If you can't solve the problem, you need manual service. If a user tries a function for many times, the user's demand for manual customer service is often more urgent.
- the second example the user's business status characteristics.
- the user's business status feature reflects the information of the account opened by the user on the consulted product, and may include the service opening status of the user account, the account authentication status, the account login status, and/or the account abnormal status.
- the user's business status feature can often reflect the user's urgency to solve the problem. If the user's account is in a state of “frozen” (an account abnormal state) or “off-site login” (an account login status), the user is likely to In the case of stolen and cheated, there will be an urgent need for manual customer service.
- the identity information of the user is information of the user as a natural person, and may include the gender, age, resident territory, and/or education level of the user. Users with different identity information characteristics usually accept different degrees of robot customer service. For example, young users and highly educated users are more accustomed to the question and answer mode of robot customer service. Older users and lower education users are more inclined to artificial customer service.

- the parameter update is performed in the sub-model, and the parameters of the two sub-models are optimized at the same time, so that the prediction ability of the overall Wide and Deep model is optimal.
- the conversation feature directly reflects the user's demand for manual customer service, which is a strong correlation feature; and the user's state feature is not directly related to the question and answer process, but only indirectly affects the user's demand for manual customer service. , is a weak correlation feature.
- different sub-models in the Wide and Deep learning model can be used to deal with these two types of features. Specifically, the session feature is used as the input of the linear sub-model, and the output vector of the linear sub-model is obtained by the linear sub-model; the state feature of the user is used as the input of the deep neural network sub-model, and processed by the deep neural network sub-model. The output vector of the deep neural network submodel is obtained; then the output vectors of the two submodels are put together and the output is calculated through a neuron.

- the second and subsequent rounds are a robot customer service speech and a user speech.
- Each round ends with a user's speech, which is the point in time at which the robotic customer service can be replaced by manual customer service, or a possible artificial point.
- One or more rounds of the robotic customer service session with the user can be used as the basis for acquiring session features. For example, the destination session number of the predetermined number of times before the current time point is used as the basis for acquiring the session feature. If the session round that has been performed at the current time point is less than the predetermined number of rounds, the entire session is used as the basis for acquiring the session feature; for example, it will always be already The entire session is performed as the basis for acquiring session characteristics.
- Step 120 Acquire a state feature of the user.
- the state characteristics of the user can be read from a predetermined network location, a predetermined database table, and the like that save the user state feature, and are not limited.

- the predetermined confidence threshold can be determined by comprehensively considering the degree of fitting of the confidence assessment sub-model and the session sample after training, and the ratio of the number of users and manual customer service in the actual application scenario. It is also possible to set a certain standard, and the program automatically determines the predetermined confidence threshold according to the set criteria.
- the session sample may be input into the trained confidence assessment model to obtain a sample confidence score corresponding to the artificial point in the session sample; a specific series of different predetermined confidence threshold values are set, and the calculation is different when the selection is different.
- the predetermined confidence value of the value is divided into thresholds, the coverage and accuracy of the sample confidence score are evaluated, and the criteria for coverage and accuracy are set. The best coverage and accuracy corresponding to the evaluation criteria are used as the predetermined confidence.
- the threshold is divided.
- the user's state feature is used to describe the user's own factors
- the session feature acquired from the robot and the user's session and the user's state feature are used as confidence to evaluate the input of the machine learning model, and the current Confidence assessment value, when the current confidence assessment value meets the predetermined manual condition, the manual customer service is transferred.
