[0018] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0019] Currently, in the conversation process between the intelligent customer service and the object, for the object's current question, the intelligent customer service determines whether the current question contains specific keywords in specific historical questions; among which, the specific historical questions are historical questions with intervention reply content; when the current question contains specific keywords, the intervention reply content is determined as the reply content corresponding to the current question.

[0020] In the above scheme, when specific keywords in specific historical questions exist in the current question, the semantics of the current question and the semantics of the specific historical question may be greatly different, resulting in the reply content not being the expected reply content of the current question and poor dialogue efficiency.

[0021] In view of the above problems, the present disclosure proposes an intelligent dialogue method, device and electronic device.

[0022] Figure 1 This is a schematic diagram according to the first embodiment of the present disclosure. It should be noted that the intelligent dialogue method of the embodiment of the present disclosure can be applied to an intelligent dialogue device, which can be configured in an electronic device so that the electronic device can perform an intelligent dialogue function. The following embodiments are described by taking the execution subject as an electronic device as an example.

[0023] Among them, the electronic device can be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a server, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, a smart speaker, a server, a server cluster, an intelligent body, and other hardware devices with various operating systems, touch screens and / or display screens.

[0024] The intelligent dialogue device may also be software in an electronic device, such as intelligent dialogue software, etc. In the following embodiments, the intelligent dialogue device is an electronic device as an example for description.

[0025] like Figure 1 As shown, the intelligent dialogue method may include the following steps:

[0026] Step 101, obtaining the current question in the conversation process.

[0027] In the disclosed embodiment, the conversation process may be a conversation process between the object and the electronic device, wherein the current question may be a question currently input by the object during the conversation process; or a question currently collected by the object during the conversation process.

[0028] Step 102, query the first database according to the current question, obtain the candidate reference questions in the first database that match the current question, and the first intervention response content corresponding to the candidate reference questions; the first database includes various reference questions and the intervention response content corresponding to the reference questions.

[0029] In an embodiment of the present disclosure, in one example, the process of the electronic device executing step 102 may, for example, be to determine, for each reference question in the first database, the similarity between the reference question and the current question; sort the reference questions in descending order according to the similarity to obtain a sorting result; determine a preset number of reference questions at the top of the sorting result as candidate reference questions; and obtain first intervention reply content corresponding to the candidate reference questions in the first database.

[0030] In another example, the process of the electronic device executing step 102 may be, for example, determining the similarity between the reference question and the current question for each reference question in the first database; determining the reference questions whose corresponding similarity is greater than or equal to a preset similarity threshold as candidate reference questions; and obtaining the first intervention reply content corresponding to the candidate reference questions in the first database.

[0031] The similarity between the reference question and the current question can be determined by combining the keywords in the reference question and the keywords in the current question. For example, the electronic device can determine a first number of identical keywords in the keywords in the reference question and the keywords in the current question; determine a second number of keywords in the current question; and determine the ratio of the first number to the second number as the similarity between the reference question and the current question.

[0032] In the disclosed embodiment, the first database may be determined by the electronic device, or may be determined by other devices that communicate with the electronic device. Taking the electronic device determining the first database as an example, the process of the electronic device determining the first database may be, for example, determining the intervention party; providing an interactive interface to the intervention party to provide the historical conversation record to the intervention party through the interactive interface, and receiving the intervention information returned by the intervention party. The intervention information may include historical questions in the historical conversation record and the intervention reply content corresponding to the historical questions. The electronic device may determine the first database in combination with multiple intervention information.

[0033] It should be noted that the conversation process between the electronic device and the object can be triggered based on advertisements, links, etc. The content displayed by the advertisements or links, etc. is the relevant content of the intervening party. Correspondingly, the conversation process between the electronic device and the object involves the relevant content of the intervening party. Therefore, the intervening party can be the party to which the content displayed by the advertisements or links, etc., which trigger the conversation process belongs.

[0034] Step 103: Determine whether the first intervention reply content is available according to the current question, the first intervention reply content and the availability judgment model.

[0035] In the disclosed embodiment, the process of the electronic device executing step 103 may, for example, be to input the current question and the first intervention reply content into an availability judgment model, obtain an availability judgment result output by the availability judgment model; and determine whether the first intervention reply content is available based on the availability judgment result.

[0036] The availability judgment result may be a specific numerical value. Different numerical values ​​are used to represent different availability judgment results. For example, when the availability judgment result is a first numerical value, it indicates that the first intervention reply content is available; when the availability judgment result is a second numerical value, it indicates that the first intervention reply content is unavailable.

[0037] Among them, the first intervention reply content is available, which may mean that the match between the current question and the first intervention reply content is high, and the first intervention reply content can be used as the current reply content corresponding to the current question. The first intervention reply content is unavailable, which may mean that the match between the current question and the first intervention reply content is low, and the first intervention reply content cannot be used as the current reply content corresponding to the current question.

[0038] In the disclosed embodiment, the availability judgment model can be obtained by fine-tuning the generative large language model based on the training data, wherein the training data may include sample questions, sample intervention answer content, and whether it is available.

[0039] In which, the availability judgment model and the current question are combined to determine whether the first intervention reply content is available. Based on the large number of parameters in the availability judgment model and the high judgment accuracy, the matching degree between the first intervention reply content and the current question can be further accurately determined, thereby further improving the matching degree between the determined current reply content and the current question, and further improving the dialogue efficiency.

[0040] Step 104, when the first intervention reply content is available, generate the current reply content corresponding to the current question according to the current question and the first intervention reply content.

[0041] In an embodiment of the present disclosure, when the number of available first intervention reply contents is single, the process for the electronic device to execute step 104 may, for example, be to input the current question and the first intervention reply content into a generative large language model, and obtain the current reply content output by the generative large language model.

[0042] In an embodiment of the present disclosure, when there are multiple available first intervention reply contents, the process for the electronic device to execute step 104 may, for example, be to select one candidate reference question from multiple candidate reference questions based on the degree of match between the candidate reference questions corresponding to the available first intervention reply contents and the current question; input the first intervention reply content corresponding to the selected candidate reference question and the current question into the generative large language model, and obtain the current reply content output by the generative large language model.

[0043] The degree of match between the candidate reference question corresponding to the available first intervention reply content and the current question may be the degree of similarity between the candidate reference question and the current question in step 102 .

[0044] Among them, the electronic device can sort the candidate reference questions corresponding to the available multiple first intervention reply contents in descending order based on the matching degree to obtain a sorting result; and determine the candidate reference question ranked first in the sorting result as the selected candidate reference question.

[0045] Among them, by combining the matching degree between the candidate reference questions corresponding to the available first intervention reply content and the current question, selecting a candidate reference question from multiple candidate reference questions, and then determining the current reply content, can further improve the matching degree between the determined current reply content and the current question. In addition, combining the generative large language model, the current question, and the first intervention reply content to generate the current reply content can ensure the style consistency between the current question and the current reply content, thereby further improving the dialogue efficiency.

[0046] In the embodiments of the present disclosure, it is also necessary to explain that, when no available first intervention reply content is obtained, the electronic device can generate current reply content corresponding to the current question in combination with the current question; or, the electronic device can generate current reply content corresponding to the current question in combination with the current question and historical conversation content.

[0047] The intelligent dialogue method of the disclosed embodiment obtains the current question in the dialogue process; queries the first database according to the current question to obtain the candidate reference question matching the current question in the first database, and the first intervention reply content corresponding to the candidate reference question; the first database includes each reference question and the intervention reply content corresponding to the reference question; determines whether the first intervention reply content is available according to the current question, the first intervention reply content and the availability judgment model; and generates the current reply content corresponding to the current question according to the current question and the first intervention reply content when the first intervention reply content is available; wherein, the candidate reference question is selected based on the matching degree between the current question and the reference question, and then the intervention reply content is selected based on whether the intervention reply content corresponding to the candidate reference question is available to generate the current reply content, which can ensure that the current reply content is the expected reply content for the current question, thereby improving the dialogue efficiency.

[0048] In order to further improve the matching degree between the current question and the candidate reference questions, and thus further improve the accuracy of the current answer content, the candidate reference questions can also be selected by combining the vector similarity between the current question vector of the current question and the reference question vector of the reference question. Figure 2 As shown, Figure 2 is a schematic diagram according to a second embodiment of the present disclosure, Figure 2 The illustrated embodiment may include the following steps:

[0049] Step 201, obtaining the current question in the conversation process.

[0050] Step 202, determining a current question vector of a current question.

[0051] In the embodiments of the present disclosure, the vector extraction method for determining the current question vector may include at least one of the following: a word-based vector representation model (Word2Vec), a word-based ranking model (WordRank), a general text representation vector model (General Text Embedding, GTE), a vector model (embedding) in a generative large language model, etc., which can be selected according to actual needs and is not specifically limited here.

[0052] Step 203, query the first database according to the current question vector to obtain a reference question vector in the first database that matches the current question vector; the first database includes each reference question, a reference question vector of the reference question, and intervention answer content corresponding to the reference question.

[0053] Among them, the reference question vector of the reference question in the first database can also be extracted and processed based on at least one of the above-mentioned vector extraction methods, which is not specifically limited here.

[0054] In an embodiment of the present disclosure, in one example, the process of the electronic device executing step 203 may, for example, be to determine the vector similarity between the current question vector and each reference question vector in the first database; and determine the reference question vector whose corresponding vector similarity is greater than or equal to the first similarity threshold as the reference question vector that matches the current question vector.

[0055] Among them, combining the vector similarity between the current question vector and each reference question vector in the first database, selecting a matching reference question vector from each reference question vector can further improve the matching degree between the reference question vector and the current question vector, thereby further improving the matching degree between the candidate reference question and the current question.

[0056] In another example, the process of the electronic device executing step 203 may, for example, be to determine the vector similarity between the current question vector and each reference question vector in the first database; sort the reference question vectors in the first database in descending order according to the vector similarity to obtain a sorting result; and determine a certain number of reference question vectors ranked at the front in the sorting result as reference question vectors that match the current question vector.

[0057] In addition, the electronic device can also combine an approximate nearest neighbor search algorithm (ANN) to determine a reference question vector in the first database that matches the current question vector. The approximate nearest neighbor search algorithm, for example, a local sensitive hashing algorithm, a vector quantization algorithm, a graph embedding method, etc., can be set according to actual needs.

[0058] Step 204: determine the reference question corresponding to the matched reference question vector as a candidate reference question.

[0059] Step 205: Obtain the first intervention response content corresponding to the candidate reference question in the first database.

[0060] Step 206: Determine whether the first intervention reply content is available based on the current question, the first intervention reply content, and the availability judgment model.

[0061] Step 207, when the first intervention reply content is available, generate the current reply content corresponding to the current question according to the current question and the first intervention reply content.

[0062] In the embodiment of the present disclosure, when there are multiple available first intervention reply contents, the process for the electronic device to execute step 207 may, for example, be to obtain a reference question vector of a candidate reference question corresponding to the available first intervention reply contents; obtain a current question vector of the current question; select one candidate reference question from each candidate reference question based on the vector similarity between the reference question vectors of each candidate reference question and the current question vector; and generate the current reply content corresponding to the current question based on the first intervention reply contents corresponding to the selected candidate reference question and the current question.

[0063] Among them, the electronic device can sort the similarities of each vector in descending order to obtain a sorting result; obtain a reference question vector corresponding to the vector similarity ranked first in the sorting result; obtain a candidate reference question corresponding to the reference question vector; and generate a current reply content corresponding to the current question by combining the first intervention reply content corresponding to the candidate reference question and the current question.

[0064] It should be noted that the details of step 201, step 206 to step 207 can be found in Figure 1 Step 101, step 103 to step 104 in the illustrated embodiment will not be described in detail here.

[0065] The intelligent dialogue method of the embodiment of the present disclosure obtains the current problem in the dialogue process; determines the current problem vector of the current problem; queries the first database according to the current problem vector to obtain the reference problem vector matching the current problem vector in the first database; the first database includes various reference problems, reference problem vectors of the reference problems, and intervention reply contents corresponding to the reference problems; determines the reference problem corresponding to the matching reference problem vector as a candidate reference problem; obtains the first intervention reply contents corresponding to the candidate reference problem in the first database; determines whether the first intervention reply contents are available according to the current problem, the first intervention reply contents, and the availability judgment model; and generates the current reply contents corresponding to the current problem according to the current problem and the first intervention reply contents when the first intervention reply contents are available; wherein, the candidate reference problem is selected in combination with the vector similarity between the current problem vector of the current problem and the reference problem vector of the reference problem, and then the intervention reply contents are selected to generate the current reply contents, which can further ensure the matching degree between the candidate reference problem and the current problem, thereby improving the accuracy of the current reply contents and further improving the dialogue efficiency.

[0066] In order to further improve the matching degree between the current answer content and the current question, when the first database does not obtain the candidate reference question, the current question and the corresponding historical conversation content can be summarized; based on the processed current summary content, the second database is queried to obtain the matching candidate reference summary content, and then the current answer content is determined. Figure 3 As shown, Figure 3 is a schematic diagram according to a third embodiment of the present disclosure, Figure 3 The illustrated embodiment may include the following steps:

[0067] Step 301, obtaining the current question in the conversation process.

[0068] Step 302, query the first database according to the current question, obtain the candidate reference questions in the first database that match the current question, and the first intervention response content corresponding to the candidate reference questions; the first database includes various reference questions and the intervention response content corresponding to the reference questions.

[0069] Step 303: Determine whether the first intervention reply content is available according to the current question, the first intervention reply content and the availability judgment model.

[0070] Step 304, when the first intervention reply content is available, generate the current reply content corresponding to the current question according to the current question and the first intervention reply content.

[0071] Step 305, when no candidate reference question is obtained, or when no available first intervention reply content is obtained, historical dialogue content corresponding to the current question in the dialogue process is obtained.

[0072] In the disclosed embodiment, the historical conversation content corresponding to the current question may be the content of multiple rounds of conversations before the current question in the conversation process to which the current question belongs. The content of multiple rounds of conversations and the current question may be content under the same topic.

[0073] Step 306, summarize the current question and the historical conversation content to obtain the current summary content.

[0074] In the embodiment of the present disclosure, the process of the electronic device executing step 306 may, for example, be to input the current question and the historical conversation content into the content summary model, and obtain the current summary content output by the content summary model; the content summary model is obtained by fine-tuning the generative large language model based on the training data; the training data includes sample questions, sample historical conversation content and sample summary content.

[0075] The current summary content may include two parts, namely, historical compressed content and question completion content. The historical compressed content is the content obtained by summarizing the historical conversation content. The question completion content is the content obtained by completing and summarizing the question in combination with the historical conversation content. Correspondingly, the sample summary content may also include sample historical compressed content and sample question completion content, so that the trained content summary model can output historical compressed content and question completion content after inputting the current question and historical conversation content; the two contents are combined to obtain the current summary content.

[0076] Among them, the fine-tuning process of the generative large language model based on training data can be, for example, inputting sample questions and sample historical conversation content into the generative large language model to obtain the prediction summary content output by the generative large language model; combining the sample summary content, the prediction summary content and the loss function to determine the loss function value; and adjusting the parameters of the generative large prediction model based on the loss function value to achieve training.

[0077] Among them, the content summarization model has a large number of parameters and high accuracy. Determining the current summary content based on the content summarization model can further improve the accuracy of the determined current summary content.

[0078] In an embodiment of the present disclosure, a method for acquiring training data may include: acquiring multiple sample questions, and sample historical conversation content corresponding to the sample questions; determining prompt content; the prompt content instructs summary content generation processing; inputting the sample questions, the sample historical conversation content corresponding to the sample questions, and the prompt content into a generative large language model to acquire sample summary content output by the generative large language model; and combining the sample questions, the sample historical conversation content corresponding to the sample questions, and the sample summary content to obtain training data.

[0079] Among them, the method for obtaining sample questions and corresponding sample historical conversation contents can be, for example, collecting historical questions and corresponding historical conversation contents from various industries; performing conversation cleaning processing on the collected data, for example, ambiguous conversation filtering, low-quality conversation filtering, etc., and determining the filtered historical questions as sample historical questions; and determining the historical conversation contents corresponding to the sample historical questions as sample historical conversation contents.

[0080] Among them, the prompt content is used to instruct the summary content generation process. That is to say, combined with the prompt content, the generative large language model can understand what content needs to be generated, and then perform the generation process, so as to generate the required sample summary content, thereby improving the determination efficiency and accuracy of the sample summary content and reducing the preparation cost of training data.

[0081] Among them, in order to further ensure the accuracy of the training data, after obtaining the training data, the training data can be provided to the reviewer, and the reviewer will review whether the content of each sample summary in the training data is correct, and then the accuracy of the training data; when the accuracy of the training data is greater than or equal to the accuracy threshold, the training data is retained for training processing; when the accuracy of the training data is less than the accuracy threshold, the prompt content is adjusted, and the sample summary content generation processing is rewritten in combination with the generative large language model until the training data with an accuracy greater than or equal to the accuracy threshold is obtained.

[0082] Step 307, query the second database according to the current summary content, obtain the candidate reference summary content in the second database that matches the current summary content, and the second intervention reply content corresponding to the candidate reference summary content; the second database includes each reference summary content and the intervention reply content corresponding to the reference summary content.

[0083] In an embodiment of the present disclosure, in one example, the process of the electronic device executing step 307 may be, for example, determining, for each reference summary content in the second database, the similarity between the reference summary content and the current summary content; selecting candidate reference summary content from multiple reference summary contents based on the similarity; and obtaining second intervention reply content corresponding to the candidate reference summary content in the second database.

[0084] In another example, the second database may also include a reference summary content vector of the reference summary content. Correspondingly, the process of the electronic device executing step 307 may be, for example, determining the current summary content vector of the current summary content; querying the second database according to the current summary content vector to obtain a reference summary content vector matching the current summary content vector in the second database; determining the reference summary content corresponding to the matching reference summary content vector as the candidate reference summary content; and obtaining the second intervention reply content corresponding to the candidate reference summary content in the second database.

[0085] Among them, combining the vector similarity between the current summary content vector and each reference summary content vector in the second database, selecting a matching reference summary content vector from each reference summary content vector can further improve the matching degree between the reference summary content vector and the current summary content vector, thereby further improving the matching degree between the candidate reference summary content and the current summary content.

[0086] In the disclosed embodiment, the second database may be determined by the electronic device, or may be determined by other devices that communicate with the electronic device. Taking the electronic device determining the second database as an example, the process of the electronic device determining the second database may be, for example, determining the intervention party; providing an interactive interface to the intervention party to provide the historical conversation record to the intervention party through the interactive interface, and receiving the intervention information returned by the intervention party. The intervention information may include historical questions, historical conversation content, and intervention reply content in the historical conversation record. The electronic device may determine the second database in combination with multiple intervention information.

[0087] It should be noted that the conversation process between the electronic device and the object can be triggered based on advertisements, links, etc. The content displayed by the advertisements or links, etc. is the relevant content of the intervening party. Correspondingly, the conversation process between the electronic device and the object involves the relevant content of the intervening party. Therefore, the intervening party can be the party to which the content displayed by the advertisements or links, etc., which trigger the conversation process belongs.

[0088] In the embodiments of the present disclosure, it is also necessary to explain that, when the candidate reference summary content is not obtained, the electronic device can generate the current reply content corresponding to the current question in combination with the current question; or, the electronic device can generate the current reply content in combination with the current summary content.

[0089] Step 308 : Determine whether the second intervention reply content is available according to the current summary content, the second intervention reply content corresponding to the candidate reference summary content, and the availability judgment model.

[0090] In the disclosed embodiment, the process of the electronic device executing step 308 may, for example, be to input the current summary content and the second intervention reply content into the availability judgment model, obtain the availability judgment result output by the availability judgment model; and determine whether the second intervention reply content is available according to the availability judgment result.

[0091] Step 309, when the second intervention reply content is available, generate the current reply content corresponding to the current question according to the current summary content and the second intervention reply content.

[0092] In the disclosed embodiment, when the available second intervention reply content is single, the electronic device can directly input the current summary content and the second intervention reply content into the generative large language model to obtain the current reply content output by the generative large language model. When the available second intervention reply content is multiple, the electronic device can select one second intervention reply content from the multiple second intervention reply contents; input the selected second intervention reply content and the current summary content into the generative large language model to obtain the current reply content output by the generative large language model.

[0093] In the embodiments of the present disclosure, it should also be noted that, when no available second intervention reply content is obtained, the electronic device can generate the current reply content corresponding to the current question in combination with the current question; or, the electronic device can generate the current reply content in combination with the current summary content.

[0094] It should be noted that the details of steps 301 to 304 can be found in Figure 1 Steps 101 to 104 in the illustrated embodiment will not be described in detail herein.

[0095] The intelligent dialogue method of the disclosed embodiment obtains the current question in the dialogue process; queries the first database according to the current question to obtain the candidate reference question matching the current question in the first database, and the first intervention reply content corresponding to the candidate reference question; the first database includes each reference question and the intervention reply content corresponding to the reference question; determines whether the first intervention reply content is available according to the current question, the first intervention reply content and the availability judgment model; generates the current reply content corresponding to the current question according to the current question and the first intervention reply content when the first intervention reply content is available; obtains the historical dialogue content corresponding to the current question in the dialogue process when the candidate reference question is not obtained or when the available first intervention reply content is not obtained; summarizes the current question and the historical dialogue content to obtain the current summary content; queries the second database according to the current summary content to obtain the second database The invention relates to a method for generating a query string comprising: a query string that contains candidate reference summary contents that match the current summary contents in the query string, and second intervention reply contents corresponding to the candidate reference summary contents; a second database that includes various reference summary contents and intervention reply contents corresponding to the reference summary contents; determining whether the second intervention reply contents are available according to the current summary contents, the second intervention reply contents corresponding to the candidate reference summary contents, and an availability judgment model; when the second intervention reply contents are available, generating the current reply contents corresponding to the current question according to the current summary contents and the second intervention reply contents; wherein, in the case that the candidate reference question is not obtained in the first database, the current question and the corresponding historical conversation contents can be summarized; based on the processed current summary contents, the second database is queried to obtain matching candidate reference summary contents, and then the current reply contents are determined, which can further ensure the matching degree between the current reply contents and the current question, thereby improving the conversation efficiency.

[0096] The following examples are used to illustrate this. Figure 4 The figure shows a schematic diagram of multiple rounds of intervention in intelligent dialogue. Figure 4The following steps may be included. Step 401, online dialogue (i.e., dialogue process).
