[0040] Figure 1The system 100 may be configured and operated in various ways to enable the application of various methods and apparatuses described in the present disclosure.

[0041] According to the embodiments of the present disclosure, Figure 2 As shown, a training method for a recommendation question generation model is provided, the method comprising: step S201, obtaining a first recommendation question, the first recommendation question being a recommendation question clicked by a user among multiple historical recommendation questions, the multiple historical recommendation questions being generated by an initial generation model according to a first user input and a first reply generated by a large language model; step S202, in response to determining that the first recommendation question meets a first screening condition, determining the first recommendation question as a positive sample recommendation question, wherein the first screening condition comprises that the semantic similarity between the first recommendation question and the first user input is less than a first threshold; step S203, based on the positive sample recommendation question, obtaining at least one sample data, each sample data in the at least one sample data comprising a first user input, a first reply, a positive sample recommendation question and a negative sample recommendation question, the at least one sample data comprising the first sample data, the negative sample recommendation question in the first sample data being a recommendation question not clicked by the user among multiple historical recommendation questions; and step S204, training the initial generation model based on the at least one sample data to obtain a recommendation question generation model.

[0042] Therefore, by further screening the recommended questions that the user has clicked on in the past, the recommended questions that have a high semantic similarity with the corresponding first user input are screened out, and the screened recommended questions are used as positive sample recommended questions. Sample data is constructed based on the positive sample recommended questions to train the model, so that the model can learn user preferences while further improving the accuracy of the recommended questions generated by the model.

[0043] In the intelligent dialogue scenario, the large language model will generate reply information based on the input information entered by the user. At the same time, the initial generation model can be applied to generate multiple recommended questions based on the input information and reply information to guide the user to ask follow-up questions. The user can click on a recommended question, and the large language model can further generate reply information for the recommended question.

[0044] In some embodiments, the initial generation model may be a model that has been preliminarily trained for generating recommendation questions, wherein the preliminarily training may be supervised training using sample data, and the sample data used for the preliminarily training may include sample input information, sample response information, and sample recommendation questions.

[0045] In some embodiments, the above initial generation model can be constructed based on a Transformer network.

[0046] In some exemplary embodiments, the initial generation model can be constructed based on a Decoder network in a Transformer network. In some examples, the initial generation model can be a causal language model.

[0047] In some embodiments, user input information and generated reply information, multiple recommended questions, and user clicks on the recommended questions in multiple historical rounds of conversations can be stored in a historical conversation database, and the recommended questions that the user has historically clicked on (i.e., the first recommended question) and the corresponding user input information and reply information (i.e., the first user input and the first reply) of the recommended question as well as other historical recommended questions corresponding to the round of conversation can be obtained therefrom.

[0048] After obtaining the first recommended question, it can be first determined whether the first recommended question and the first user input are semantically repeated. In some embodiments, semantic features can be extracted for the first recommended question and the first user input respectively, the semantic similarity between the two semantic features can be calculated, and it can be determined whether the semantic similarity is less than a first threshold. If the semantic similarity is greater than or equal to the first threshold, it is considered that the first recommended question and the first user input are semantically repeated, that is, they do not meet the first filtering condition. If the semantic similarity is less than the first threshold, it is considered that the first recommended question and the first user input are semantically non-repetitive, that is, they meet the first filtering condition.

[0049] In some embodiments, the above-mentioned judgment of semantic similarity can also be implemented based on a large language model. In some examples, the first recommended question and the first user input can be input into the large language model together with the judgment prompt text. Under the guidance of the judgment prompt text, the large language model analyzes the semantic similarity of the first recommended question and the first user input, and outputs a judgment result of whether the first recommended question and the first user input are semantically repeated. Among them, the judgment prompt text can be, for example, "You are a linguistics expert, please judge whether the semantics of the following two sentences are repeated: <Sentence 1>, <Sentence 2>".

[0050] In some embodiments, the first recommendation question that does not meet the first screening condition (ie, the recommendation question that has semantic overlap with the first user input) may be determined as a low-quality recommendation question and discarded.

[0051] In some embodiments, the first recommendation question that meets the first screening condition may be determined as a positive sample recommendation question for generating sample data.

[0052] In some embodiments, after obtaining a positive sample recommendation question, other historical recommendation questions displayed in the conversation corresponding to the recommendation question but not clicked by the user can be used as negative sample recommendation questions, and together with the first user input and the first reply, form a sample data (i.e., the first sample data). It is understandable that multiple sample data similar to the above can be constructed based on multiple historical recommendation questions that have not been clicked by users.

[0053] In some embodiments, applying each of the above sample data to train the initial generation model can be to input the first user input and the first reply into the initial generation model, so that the initial generation model analyzes the first user input and the first reply, and outputs one or more predicted recommendation questions; then, based on the difference between the predicted recommendation question and the positive sample recommendation question, and the difference between the predicted recommendation question and the negative sample recommendation question, calculate the loss function, update the parameters of the initial generation model based on the loss function, and perform the next round of training on the updated initial generation model until the model converges to obtain a recommendation question generation model.

[0054] In some embodiments, the above loss function may be a contrast loss function.

[0055] Therefore, by further screening the recommended questions that the user has clicked on in the past, the low-quality recommended questions that have a high semantic similarity with the corresponding first user input are screened out, and the high-quality recommended questions obtained by screening are used as positive sample recommendation questions. Based on the positive sample recommendation questions, sample data containing positive and negative sample pairs are constructed to train the model, so that the model can learn user preferences while enabling the model to generate recommendation questions with higher accuracy and quality.

[0056] In some embodiments, the at least one sample data may further include second sample data, and the semantic similarity between the negative sample recommendation question in the second sample data and the first user input is not less than a second threshold.

[0057] In some embodiments, one or more recommendation questions with semantics that are repeated with the first user input may be further generated based on the first user input as negative sample recommendation questions, and together with the positive sample recommendation question, the first user input and the first reply, form a piece of sample data (i.e., second sample data). It is understandable that multiple pieces of sample data may be constructed based on multiple generated negative sample recommendation questions and the positive sample recommendation questions.

[0058] In some embodiments, the above-mentioned recommendation questions that are semantically repeated with the first user input can be constructed by a large language model. In some examples, the first user input and the prompt text for constructing the recommendation questions can be input into the large language model, so that the large language model, under the guidance of the prompt text, generates one or more recommendation questions that are semantically repeated with the first user input based on the first user input. Among them, the above-mentioned prompt text can be, for example, "You are a linguistics expert, please output a question with the same semantics as <Sentence 1>" or "You are a linguistics expert, please output a question with a semantic similarity with <Sentence 1> that is not less than <Second Threshold>".

[0059] Therefore, by further constructing a low-quality recommendation question that is semantically similar to the first user input as a negative sample recommendation question, constructing sample data containing positive and negative sample pairs, and training the model through the above sample data, the model can be further enabled to generate higher-quality recommendation questions that are more in line with user preferences while avoiding the generation of low-quality recommendation questions as much as possible.

[0060] In some embodiments, the first screening condition may further include that the semantic similarity between the first recommended question and the first reply is less than a third threshold.

[0061] In some embodiments, the first screening condition may include that the semantic similarity between the first recommended question and the first user input is less than a first threshold, and the semantic similarity between the first recommended question and the first reply is less than a third threshold. The method for determining the semantic similarity between the first recommended question and the first reply is similar to the method for determining the semantic similarity between the first recommended question and the first user input, and will not be described in detail here.

[0062] Therefore, through the semantic similarity between the first recommended question and the first reply, low-quality recommended questions that are semantically repeated with the first reply can be further screened out, and the quality of positive sample recommended questions can be further improved, thereby further improving the accuracy and quality of recommended questions generated by the model.

[0063] In some embodiments, the at least one sample data may further include third sample data, and the semantic similarity between the negative sample recommendation question in the third sample data and the first reply is not less than a fourth threshold.

[0064] In some embodiments, one or more recommendation questions with semantics that are repeated with the first reply may be further generated based on the first reply as negative sample recommendation questions, and together with the positive sample recommendation question, the first user input and the first reply, form a piece of sample data (i.e., third sample data). It is understandable that multiple pieces of sample data may be constructed based on multiple generated negative sample recommendation questions and the positive sample recommendation questions.

[0065] In some embodiments, the recommended questions that are semantically repeated with the first reply can be constructed by a large language model. In some examples, the first reply and the prompt text for constructing the recommended questions can be input into the large language model, so that the large language model, under the guidance of the prompt text, generates one or more recommended questions that are semantically repeated with the first reply based on the first reply. Among them, the above prompt text can be, for example, "You are a linguistics expert, please output a question with the same semantics as <Sentence 2>" or "You are a linguistics expert, please output a question with a semantic similarity with <Sentence 2> that is not less than <Fourth Threshold>".

[0066] Therefore, by further constructing a low-quality recommendation question with similar semantics to the first reply as a negative sample recommendation question, building sample data containing positive and negative sample pairs, and training the model through the above sample data, the model can be further enabled to generate higher-quality recommendation questions that are more in line with user preferences while avoiding the generation of low-quality recommendation questions as much as possible.

[0067] In some embodiments, the first filtering condition may also include that the similarity between the conversation intention of the first recommended question and the conversation intention input by the first user is greater than a fifth threshold.

[0068] In some embodiments, the first filtering condition may include that the semantic similarity between the first recommended question and the first user input is less than a first threshold, and the similarity between the conversation intention of the first recommended question and the conversation intention of the first user input is greater than a fifth threshold.

[0069] In some embodiments, the first filtering condition may include that the semantic similarity between the first recommended question and the first user input is less than a first threshold, the similarity between the conversation intention of the first recommended question and the conversation intention of the first user input is greater than a fifth threshold, and the semantic similarity between the first recommended question and the first reply is less than a third threshold.

[0070] In some embodiments, the conversation intentions of the first recommended question and the first user input can be extracted respectively, and the similarity between the two conversation intentions (e.g., semantic similarity) can be calculated to determine whether the intention similarity is greater than a fifth threshold. If the intention similarity is less than or equal to the fifth threshold, it is considered that the first recommended question and the first user input intention are inconsistent, that is, they do not meet the first screening condition, and should be determined as low-quality recommended questions and discarded. If the intention similarity is greater than the fifth threshold, it is considered that the first recommended question and the first user input intention are inconsistent. Figure 1 After meeting other screening conditions, the problem can be judged as a high-quality recommendation problem and used as a positive sample recommendation problem.

[0071] In some embodiments, the above Figure 1The judgment of consistency can also be implemented based on the large language model. In some examples, the first recommended question and the first user input together with the judgment prompt text can be input into the large language model. Under the guidance of the judgment prompt text, the large language model can judge the dialogue meaning between the first recommended question and the first user input. Figure 1 The consistency is analyzed and the first recommendation question and the first user input are output. Figure 1 The judgment prompt text may be, for example, "You are a linguistics expert, please judge whether the conversation intentions of the following two statements are consistent: <statement 1>, <statement 2>" or "You are a linguistics expert, please judge whether the similarity of the conversation intentions of the following two statements is greater than the fifth threshold: <statement 1>, <statement 2>".

[0072] Thus, through the first recommendation question and the first user input Figure 1 Consistency can be further used to screen out low-quality recommendation questions that are significantly different from the first user’s input intention, further improving the quality of positive sample recommendation questions, thereby further improving the accuracy and quality of the recommendation questions generated by the model.

[0073] In some embodiments, at least one sample data may further include fourth sample data, and the similarity between the dialogue intention of the negative sample recommendation question in the fourth sample data and the dialogue intention input by the first user is no greater than a sixth threshold.

[0074] In some embodiments, one or more recommendation questions that are significantly different from the first user input intention may be further generated based on the first user input as negative sample recommendation questions, and together with the positive sample recommendation question, the first user input and the first reply, form a piece of sample data (i.e., fourth sample data). It is understandable that multiple pieces of sample data may be constructed based on multiple generated negative sample recommendation questions and the positive sample recommendation questions.

[0075] In some embodiments, the recommendation questions that differ greatly from the first user input intention can be constructed by a large language model. In some examples, the first user input and the prompt text for constructing the recommendation questions can be input into the large language model, so that the large language model, under the guidance of the prompt text, generates one or more recommendation questions that are inconsistent with the first user input intention based on the first user input. Among them, the above prompt text can be, for example, "You are a linguistics expert, please output a question that is inconsistent with the dialogue intention of <Sentence 1>" or "You are a linguistics expert, please output a question whose similarity with the dialogue intention of <Sentence 1> is not greater than <Sixth Threshold>".

[0076] Therefore, by further constructing a low-quality recommendation question that is greatly different from the first user's input intention as a negative sample recommendation question, constructing sample data containing positive and negative sample pairs, and training the model through the above sample data, the model can be further enabled to generate higher-quality recommendation questions that are more in line with user preferences while avoiding the generation of low-quality recommendation questions as much as possible.

[0077] It is understandable that the various thresholds mentioned above can be determined based on the actual needs of relevant technical personnel and are not limited here.

[0078] Figure 3 A flowchart of acquiring sample data according to an exemplary embodiment of the present disclosure is shown.

[0079] In some exemplary embodiments, Figure 3 As shown, the process of obtaining sample data is as follows: step S301, obtain the first recommended question; step S302, determine whether the first recommended question is semantically repeated with the first user input and the first reply; step S303, if the semantics are repeated, discard the first recommended question; step S304, if the semantics are not repeated, further determine whether the first recommended question is semantically repeated with the first user input. Figure 1 Step S305: if the intention is not consistent, the first recommended question is discarded; Step S306: if the intention is Figure 1 If the first recommendation question is the same as the first one, then the first recommendation question is determined as the positive sample recommendation question; step S307, the two recommendation questions displayed in the same round of dialogue but not clicked by the user are respectively used as the two negative sample recommendation questions of the first sample data; step S308, construct a recommendation question that is semantically repeated with the first user input as a negative sample recommendation question in the second sample data; step S309, construct a recommendation question that is semantically repeated with the first reply as a negative sample recommendation question in the third sample data; step S310, based on the above-mentioned first recommendation question, obtain 4 sample data, including 2 first sample data, one second sample data and one third sample data, each sample data includes the first user input and the first reply, a positive sample recommendation question (i.e., the first recommendation question) and a negative sample recommendation question.

[0080] In some embodiments, the sample data may be constructed based on all first recommendation questions in the database that meet the first screening condition to obtain a sample data set for training a recommendation question generation model.

[0081] In some embodiments, based on at least one sample data, training the initial generation model may include: for each sample data in the at least one sample data, performing the following operations: inputting a first prompt text and the sample data into the first generation model, so as to obtain, through the first generation model, under the guidance of the first prompt text, according to the first input, a first probability of a positive sample recommendation problem and a second probability of a negative sample recommendation problem, wherein the first generation model is the initial generation model in training; and updating the parameters of the first generation model based on the first probability and the second probability.

[0082] In some embodiments, the first generation model is the initial generation model in training, that is, when the first sample data is input, the first generation model is the initial generation model; after a round of training, the first generation model is the initial generation model after parameter update.

[0083] In some embodiments, the first prompt text can be used to guide the first generation model to output the first probability corresponding to the positive sample recommendation question and the second probability corresponding to the negative sample recommendation question according to the first user input and the first reply in the input sample data, wherein the first probability and the second probability can represent the tendency of the current first generation model for the corresponding recommendation question. For example, if the first probability is 0.9 and the second probability is 0.1, the first generation model is more inclined to generate positive sample recommendation questions.

[0084] In some embodiments, updating the parameters of the first generation model based on the first probability and the second probability may be calculating a loss function based on the difference between the first probability and the second probability, and then updating the parameters of the first generation model based on the loss function.

[0085] In some embodiments, the difference between the first probability and the second probability may be a difference in log-likelihood probabilities.

[0086] In some embodiments, the model can be trained by maximizing the above-mentioned difference until the model converges, thereby obtaining a recommendation question generation model.

[0087] Therefore, by guiding the generation model through the first prompt text to output the first probability of selecting the positive sample recommendation problem and the second probability of selecting the negative sample recommendation problem, and calculating the loss and training the model based on the first probability and the second probability, the efficiency of model training can be improved while ensuring the effectiveness of model training.

[0088] In some embodiments, based on at least one sample data, training the initial generation model may also include: in response to the parameters of the first generation model being updated at least once, for each sample data in the at least one sample data, inputting the first prompt text and the sample data into the initial generation model, so as to obtain the third probability of the positive sample recommendation problem and the fourth probability of the negative sample recommendation problem through the initial generation model under the guidance of the first prompt text and according to the first input; and wherein, based on the first probability and the second probability, updating the parameters of the first generation model may include: updating the parameters of the first generation model based on the first probability, the second probability, the third probability and the fourth probability.

[0089] In some embodiments, the sample data and the first prompt text can be input into the initial generation model (i.e., the initial generation model without updated parameters) at the same time as the sample data and the first prompt text are input into the first generation model, and the third probability and the fourth probability output by the initial generation model are obtained.

[0090] In some embodiments, based on the first probability, the second probability, the third probability and the fourth probability, updating the parameters of the first generation model can be based on the difference between the probability ratio between the first probability and the third probability and the probability ratio between the second probability and the fourth probability, determining the loss function, and then updating the parameters of the first generation model based on the loss function.

[0091] In some embodiments, the above probability ratio may be a log probability ratio.

[0092] In some embodiments, the above loss function can be expressed as the following formula:

[0093]

[0094] Among them, π θ ,π ref are the first generation model and the initial generation model in the optimization, respectively. x is the first user input, the first reply, and the first prompt text in the sample data. y w ,y l They represent the positive sample recommendation problem and the negative sample recommendation problem in the sample data respectively, β is a hyperparameter, and σ is the sigmoid function.

[0095] In this way, the initial generation model can be used as a reference object in the model training process to train the first generation model, thereby further improving the efficiency and effect of model training and improving the accuracy of recommendation question generation.

[0096] In some embodiments, Figure 4As shown, a method for generating recommendation questions is provided, the method comprising: step S401, obtaining user input information and reply information generated by a large language model according to the user input information; and step S402, processing the user input information and reply information using a recommendation question generation model to obtain at least one recommendation question output by the recommendation question generation model, wherein the recommendation question generation model is trained by the training method of the recommendation question generation model of an embodiment of the present disclosure.
