[0007] In an alternative manner, detecting whether task parameters of the earliest output task to be executed in the task queue are missing includes: detecting the value of each task parameter corresponding to the earliest output task to be executed in the task queue, and detecting whether the parameter filling value corresponding to the earliest output task to be executed is less than a preset value; wherein, the parameter filling value is based on the ratio of the number of already supplemented parameters to the total number of supplemented parameters required for execution; if the value of any task parameter is empty and the parameter filling value is less than the preset value, it indicates that the task parameters of the earliest output task to be executed in the task queue are missing.

[0008] In an alternative manner, generating an inquiry statement required for output based on the missing task parameters includes: matching the corresponding preset inquiry fields based on the missing task parameters; inputting the corresponding preset inquiry fields into a preset function function corresponding to the missing task parameters to generate an inquiry statement required for output.

[0010] In an alternative manner, performing a matching operation between the instruction information represented by the voice instruction and multiple preset task descriptions includes: if the instruction information represented by the voice instruction fails to match all preset task descriptions, outputting a prompt voice to prompt the user to reissue the voice instruction.

[0011] In an alternative manner, the management method further includes: training an evaluation model based on a preset number of training samples to obtain a trained evaluation model; wherein, the training samples include task samples and task descriptions corresponding to the task samples; inputting the tasks in the updated task set into the trained evaluation model to obtain scores for each task; and selecting the fixed number of initial tasks from the tasks with scores from high to low as the multiple preset tasks.

[0012] According to another aspect of the present application, a management device for instruction-based tasks is provided.

[0013] According to one aspect of the present application, an electronic device is provided, including: a controller; a memory, configured to store one or more programs, and when the one or more programs are executed by the controller, to execute the above management method.

[0016] The present application does not need to add preset tasks for task matching of user voice instructions, that is, it does not need to adapt to the matching scenario by adding a large amount of labeled data, but instead updates a fixed number of preset tasks in real time to ensure the matching adaptability of the preset tasks in real time. At the same time, according to the confirmation information fed back by the user, it is determined whether the to-be-confirmed task is the to-be-executed task, so as to strengthen the information interaction with the user, avoid deviating from the intention of the instruction information represented by the voice instruction, and adaptively adjust the output order of the to-be-executed task according to the confirmation result and the storage status of the task queue, so as to focus on the management of the instruction-based tasks of the user voice instruction and avoid the disorder of the order of the to-be-executed tasks.

[0026] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0027] The block diagrams shown in the accompanying drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0028] The flowcharts shown in the accompanying drawings are only exemplary illustrations, and do not necessarily include all content and operations / steps, nor do they necessarily need to be executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to the actual situation.

[0029] As used in this application, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0030] The task-based question-and-answer model requires a large amount of labeled data in the early stage, resulting in a high cost for model training and making the model data complicated. At the same time, if the user's voice instruction is an instruction for performing a multi-intent task, the relevant task-based question-and-answer model will have a situation of chaotic task execution.

[0031] For this reason, one aspect of this application provides a management method for instruction-based tasks. For details, please refer to Figure 1 , Figure 1 is a schematic flowchart of a management method for instruction-based tasks shown in an exemplary embodiment of this application. This management method at least includes S110 to S130, which are introduced in detail as follows:

[0032] S110: In response to the user's voice instruction, according to the instruction information represented by the voice instruction, determine the to-be-confirmed task from multiple preset tasks for output, so that the user can determine whether the to-be-confirmed task is the to-be-executed task specified by the voice instruction; among them, the multiple preset tasks are a fixed number of tasks determined from the updated task set.

[0033] A voice instruction is an instruction-based statement issued by the user carrying the user's intention, and the instruction information it represents includes, but is not limited to, the intention or task that the user expects to execute, and information such as the execution time. The voice instruction can be an imperative statement, an interrogative statement, etc. For example, the voice instruction can be "Please book a flight ticket", or "What are the steps to book a flight ticket on the mobile phone?".

[0034] The related technology directly determines the task that the user expects to execute based on a voice command of the user. In this way, relatively large errors are likely to occur, and there are relatively high requirements for the coverage scenarios, quantity, etc. of the sample data (preset tasks). This application strengthens the information interaction with the user, extracts the intention of the user (i.e., the task to be confirmed) based on the command information represented by the voice command. In order to avoid understanding deviations, the task to be confirmed is returned to the user so that the user can confirm whether the task to be confirmed is the task that the user expects to execute, that is, by obtaining the confirmation information of the user to reconfirm the recognized task to be confirmed, and avoid deviating from the intention of the command information represented by the voice command, thereby improving the accuracy of recognizing the voice command. Exemplarily, the voice command is "What are the steps to book a flight on the mobile phone?", and the determined task to be confirmed is "Book a flight on the mobile phone", then the query statement is output: "Do you want to book a flight on the mobile phone? If so, please reply yes, otherwise, please reply no.", to obtain the confirmation result of the user; if the user answers: "Yes", it indicates that the task to be confirmed is the task that the user expects to execute, that is, the task to be confirmed is the task to be executed specified by the voice command.

[0035] In addition, the number of preset tasks used for task matching in this application is fixed, and the preset tasks are tasks determined from a task set that is updated in real time. For example, the number of preset tasks is 100. As the requirements of the scenario change, or the task change trend represented by the command, the task set is adaptively updated. Instead of blindly increasing the number of preset tasks, the inapplicable tasks are replaced in real time, so that the task matching process is more lightweight.

[0036] S120: If it is yes, and there is no task to be executed stored in the task queue, then add the task to be executed as the last output task to be executed in the task queue.

[0037] This application introduces a task queue to manage the output order of multiple tasks to be executed. The task queue outputs the tasks to be executed in sequence, so that each task to be executed is executed in sequence; among them, the task queue follows the principle of first in, first out, that is, the task to be executed stored in the task queue first is output first, thus ensuring the orderliness of the execution order of the tasks to be executed.

[0038] If the confirmation result feedback by the user indicates that the task to be confirmed is the task to be executed specified by the voice command, and there is no such task to be executed stored in the task queue, it indicates that the task to be executed is a newly added task that the user expects to execute, and it is stored in the task queue, and is defaulted to the last output task to be executed in the current task queue.

[0039] S130: If it is yes, and there is a task to be executed stored in the task queue, then adjust the task to be executed to the first output task to be executed in the task queue.

[0040] If the confirmation result fed back by the user indicates that the task to be confirmed is the task to be executed specified by the voice command, and the task to be executed is stored in the task queue, then it indicates that the task to be executed has been configured with a corresponding output order, that is, the task to be executed corresponding to the voice command is already in the output arrangement of the task queue; on another level, it indicates that the same task to be executed has been repeatedly recognized, and it can be perceived that the user is eager to execute the task to be executed. The present application adjusts the position of the task to be executed in the task queue so that it is the first task to be executed output in the current task queue, focuses on the user's current voice command, and outputs the task to be executed from the task queue first, so as to respond to the user's urgent needs first, thereby improving user satisfaction.

[0041] This embodiment does not need to add preset tasks for task matching of user voice commands, that is, it does not need to adapt the matching scene by adding a large amount of annotated data, but updates a fixed number of preset tasks in real time to ensure the matching adaptability of the preset tasks in real time. At the same time, it determines whether the task to be confirmed is a task to be executed based on the confirmation information fed back by the user, so as to strengthen the information interaction with the user, avoid deviation from the intention of the instruction information represented by the voice command, and adaptively adjust the output order of the tasks to be executed based on the confirmation result and the storage status of the task queue, so as to focus on the management of the instruction-type tasks of the user's voice command and avoid confusion in the order of the tasks to be executed.

[0042] The related technology lacks execution management of tasks to be executed, which leads to execution confusion or omission of related tasks to be executed.

[0043] To this end, in another exemplary embodiment of the present application, how to execute each task to be executed in the task queue is described in detail. Figure 2 , Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for managing command-type tasks. Figure 1 Based on the S110 to S130 shown, at least S210 to S230 are also included, which are described in detail as follows:

[0044] S210: Detect whether the task parameters of the first task to be executed outputted in the task queue are missing.

[0045] The first pending tasks output by the task queue are the tasks that need to be executed urgently. When executing pending tasks, the support of relevant task parameters is required to ensure that the pending tasks are executed smoothly. Among them, task parameters are the relevant parameters required when executing tasks, including but not limited to the execution time, execution action, execution object and other parameters of the pending tasks.

[0046] S220: If there is a missing parameter, an inquiry statement required for output will be generated based on the missing task parameter to obtain supplementary information output by the user in response to the inquiry statement, and the required missing parameter will be extracted from the supplementary information until the task parameters of the to-be-executed task output first are complete.

[0047] If a task parameter is missing, the to-be-executed task may be executed unsuccessfully, or the execution may be terminated or incomplete. To ensure the smooth execution of the to-be-executed task, an inquiry statement can be generated based on a preset format so that the user is aware of the missing task parameter and replies with corresponding supplementary information. Thus, the execution entity of this application can extract the corresponding missing parameter from the supplementary information. By analogy, multiple rounds of inquiries can be made until all missing task parameters are supplemented.

[0048] The following is a detailed introduction on how to generate an inquiry statement required for output based on the missing task parameter:

[0049] Match the corresponding preset inquiry field based on the missing task parameter; input the corresponding preset inquiry field into the preset function corresponding to the missing task parameter to generate the inquiry statement required for output.

[0050] Among them, both the preset inquiry field and the preset function are corresponding to the corresponding missing task parameter. By setting the corresponding relationship between them, the corresponding preset inquiry field and preset function can be quickly matched according to the missing task parameter.

[0051] Exemplarily, if the missing task parameter is the leave date in the leave task, the corresponding preset inquiry fields are "start date of leave" and "end date of leave". Inputting them into the following preset function can automatically generate an inquiry statement: "Please provide the start date and end date of the leave".

[0052] <Function function>Leave< / Function function>

[0053] <Missing parameter>

[0054] {

[0055] "start_date":{

[0056] "type":"string",

[0057] "description":"Leave start date, YYYY-MM-DD"

[0058] },

[0059] "end_date":{

[0060] "type":"string",

[0061] "description": "End date of leave, YYYY-MM-DD"

[0062] },

[0063] }

[0064] < / Missing parameter>

[0065] S230: Call the preset interface to execute the first output task to be executed with complete task parameters until the execution is successful or the number of executions reaches the preset number of times.

[0066] The first output task to be executed in the task queue is also the first task to be executed. This application can execute the task to be executed through a preset structure. If the execution is successful, the value of exec_state (execution result) of the task to be executed is success. If the execution fails, the preset interface is called again to execute the task to be executed, and so on until the value of exec_state is updated to success. If the execution is still not successful after reaching the preset number of times, the value of exec_state is updated to fail to end the execution of the task to be tested.

[0067] This embodiment provides a method for obtaining task parameters before executing a task to be executed. By generating an interrogation statement for missing parameters, the missing parameters in the user's supplementary information are captured, so that through multiple interactions with the user, the task parameters required for execution are improved. At the same time, this embodiment further introduces the method of executing a task to be executed, that is, calling a preset interface to execute, and setting a preset number of times to provide multiple execution opportunities to avoid inaccurate execution results due to too few execution times.

[0068] In some embodiments, the above S210 at least includes S211 to S212, which are introduced in detail as follows:

[0069] S211: Detect the value of each task parameter corresponding to the first output task to be executed in the task queue, and detect whether the parameter filling value corresponding to the first output task to be executed is less than the preset value; wherein, the parameter filling value is based on the ratio of the number of supplemented parameters to the total number of supplemented parameters required for execution.

[0070] During the execution of the task to be executed, three important parameters are involved, including Parameter (task parameter set), param_state (parameter filling value), and exec_state (execution result). Among them, the value of the task parameter is the direct parameter indicating whether it is missing. For example, if the value of a certain task parameter is None, it indicates that the task parameter is empty, that is, the task parameter is missing. The parameter filling value is the filling progress of the task parameters required to execute the task to be executed. If the task parameters are complete, the parameter filling value is the maximum value. The execution result includes two results: success and failure, and param_state = the number of filled parameters / the total number of missing parameters.

[0071] The preset value can be adjusted according to the actual scenario. If it is to ensure the completeness of the task parameters, it can be set to 100%, that is, the parameter filling needs to be completed 100% to meet one of the conditions for the completeness of the task parameters. By detecting the value of the task parameter and the parameter filling value, the detection result of whether the task parameter is missing can be made more accurate.

[0072] S212: If the value of any task parameter is empty and the parameter filling value is less than the preset value, it indicates that the task parameters of the first output task to be executed in the task queue are missing.

[0073] In this application, the value of each task parameter is detected, and the filling progress of the entire task parameter also needs to be monitored. Only when all task parameters are not empty and the parameter filling value reaches the preset value can it be determined that the task parameters of the corresponding task to be executed are complete.

[0074] Exemplarily, traverse all task parameters in Parameter to determine the task parameters with empty values as missing parameters; if a task parameter with an empty value is detected and the parameter filling value does not reach the preset value, it is determined that the task parameters of the current task to be executed are missing, and the missing task parameters need to be further supplemented to ensure the smooth execution of the current task to be executed.

[0075] The reference of the related task-based Q&A model for speech command recognition depends on the task name, that is, directly matching the text information extracted from the speech command with the preset task name. Due to the diversity of Chinese expressions: synonymous words, different expression patterns with the same meaning, etc., it is easy to miss matches. To solve this technical problem, the related technologies are all constantly increasing the number of preset task names, which will make the model too heavy.

[0076] For this reason, in another exemplary embodiment of this application, a lightweight task matching method is introduced in detail. For details, please refer to Figure 3 , Figure 3 is based on Figure 1Schematic flowchart of another method for managing instruction-based tasks shown in the exemplary embodiment. This management method, in S110 as shown in Figure 1 includes at least S310 to S320, which are introduced in detail as follows:

[0077] S310: Match the instruction information represented by the voice instruction with multiple preset task descriptions; where each preset task description corresponds to a corresponding preset task.

[0078] This application does not directly match the instruction information with the preset task names, but introduces preset task descriptions to perform task matching on the instruction information. Because the preset task descriptions can cover tasks with the same meaning but different names, to avoid missing preset tasks with the same meaning due to different expressions during the matching process, thereby improving the accuracy of task matching.

[0079] The instruction information may match successfully with at least one preset task. Here, the so-called "matching successfully" means the case where the matching degree reaches a preset value. For example, the case where the matching degree reaches 70% is defined as the case of successful matching.

[0080] If the instruction information represented by the voice instruction fails to match all the preset task descriptions, a prompt voice is output to prompt the user to issue the voice instruction again. This situation may be caused by the user's poor expression, enabling the user to reorganize the voice and issue the instruction again. This situation may also be that the field involved in the voice instruction has a large difference from the field of the preset task, and preset tasks with the same field can be replaced for task matching, thereby ensuring the smooth progress of task matching.

[0081] Each preset task description corresponds to at least one preset task. For example, the preset task description: "The hotel reservation function is designed to reserve a hotel for the user" corresponds to the preset tasks including: "Reserve a hotel", "Activate the hotel reservation function", "Search for a hotel", etc.

[0082] S320: Output the preset task corresponding to the preset task description with the highest matching degree as the task to be confirmed.

[0083] In order to match more accurate preset tasks, the matching degrees can be sorted to determine the preset task description with the highest matching degree, and the corresponding preset task is used as the task to be confirmed.

[0084] In some embodiments, multiple preset tasks corresponding to the preset task description with the highest matching degree can also be filtered. For example, the instruction information represented by the voice command is: "Search for a nearby hotel", and the preset task description with the highest matching degree is "The hotel reservation function is designed to reserve a hotel for users". Then, the preset task with the highest matching degree: "Search for a hotel" is selected from the corresponding preset tasks: "Reserve a hotel", "Open the hotel reservation function", "Search for a hotel" as the task to be confirmed.

[0085] In this embodiment, according to the preset task description and the instruction information represented by the voice command, the corresponding task to be confirmed is accurately determined. Compared with the matching method directly based on the preset task name in the related art, this embodiment can avoid the occurrence of missed matching, thereby improving the accuracy of the task to be confirmed.

[0086] In another exemplary embodiment of the present application, the origin of the preset task is introduced in detail. For details, please refer to Figure 4 , Figure 4 is a schematic flowchart of another instruction-based task management method shown in any of the exemplary embodiments shown in Figures 1 to 3 The management method at least further includes S410 to S430, which are introduced in detail as follows:

[0087] S410: Train an evaluation model based on a preset number of training samples to obtain a trained evaluation model; wherein, the training samples include task samples and task descriptions corresponding to the task samples.

[0088] S420: Input the tasks in the updated task set into the trained evaluation model to obtain the scores of each task.

[0089] S430: Select a fixed number of initial tasks as multiple preset tasks from the tasks with scores from high to low.

[0090] Exemplarily, use cross-encoder as the evaluation model and use thousands of training samples annotated by the business to train the evaluation model, thereby obtaining a trained evaluation model. Examples of the training samples are as follows:

[0091] {"question": "What are the steps to book a flight on the mobile phone?", "task description": "The flight reservation function is designed to reserve a hotel for users", "label": 1}

[0092] {"question": "What are the steps to book a flight on the mobile phone?", "task description": "The hotel reservation function is designed to reserve a hotel for users", "label": 0}

[0093] Among them, "1" indicates that the question and the task description point to the same task, and "0" indicates that the question and the task description are not the same task.

[0094] Input the tasks in the updated task set into the trained evaluation model to score each task and obtain the scores of each sentence; each sentence includes a preset task and a task description corresponding to the preset task. An example of the scoring result is as follows:

[0095] {"Question": "What are the steps to book a flight on the mobile phone?", "Task description": "The flight booking function is designed to book hotels for users", "Score": 0.98}

[0096] {"Question": "What are the steps to book a flight on the mobile phone?", "Task description": "The hotel booking function is designed to book hotels for users", "Score": 0.01}

[0097] Based on the scores, following the principle of descending scores, select the top K tasks as the current preset tasks.

[0098] This application uses a small number of preset tasks without setting or adding a large number of preset tasks to identify the command-type tasks in the voice commands. Instead, it scores each current task based on the trained model to select a fixed number of tasks with higher scores as the preset tasks to achieve the purpose of lightweight task management.

[0099] In another exemplary embodiment of this application, an exemplary description of the application scenarios of the above-mentioned multiple management methods is provided. For details, please refer to Figure 5 , Figure 5 is a schematic diagram of the application scenario of the management method for command-type tasks of this application. It includes user 100, display interface 200, and task-based question-and-answer system 300. This application does not limit the connection method between them. The task-based question-and-answer system 300 serves as the execution subject of the management method shown in any of the above exemplary embodiments to execute any of the above management methods. An exemplary description is as follows:

[0100] The user 100 issues a voice command to the task-based question-and-answer system 300. The task-based question-and-answer model in the task-based question-and-answer system 300 responds to the voice command, determines the task to be confirmed from multiple preset tasks in the preset task set and outputs it, and outputs it to the display interface 200 or broadcasts an inquiry statement by voice so that the user 100 can determine whether the task to be confirmed is the task to be executed specified by the voice command; if so, detect the task detection module in the task-based question-and-answer system 300 to detect whether the task queue stores the task to be executed; if it exists, adjust the task to be executed to the task to be executed that is output first in the task queue; if it does not exist, add the task to be executed as the task to be executed that is output last in the task queue.

[0101] The task status management module in the task-based question-answering system 300 detects whether the task parameters of the currently first-output task to be executed in the task queue are missing; if missing, the task status management module generates an inquiry statement required for output based on the missing task parameters, outputs it to the display interface 200 or broadcasts the inquiry statement by voice, so as to obtain the supplementary information output by the user in response to the inquiry statement, and extracts the required missing parameters from the supplementary information until the task parameters of the first-output task to be executed are complete.

[0110] A calling module, configured to call a preset interface to execute the first-output task to be executed with complete task parameters until the execution is successful or the number of execution times reaches a preset number of times.

[0111] In another exemplary embodiment, the detection module includes:

[0112] A detection unit, configured to detect the values of each task parameter corresponding to the first output task to be executed in the task queue, and to detect whether the parameter filling value corresponding to the first output task to be executed is less than a preset value; wherein, the parameter filling value is based on the ratio of the number of supplemented parameters to the total number of supplemented parameters required for execution;

[0113] A detection result unit, configured to indicate that the task parameters of the first output task to be executed in the task queue are missing if the value of any task parameter is empty and the parameter filling value is less than a preset value.
