The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Figure 1 An exemplary system architecture 100 is shown to which an embodiment of a method for generating an interactive cooking tutorial or an apparatus for generating an interactive cooking tutorial of the present application can be applied.

[0044] like Figure 1As shown, the system architecture 100 may include a terminal device 101, a network 102 and a server 103. The network 102 is used to provide a medium for a communication link between the terminal device 101 and the server 103. The network 102 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0045] The user can use the terminal device 101 to interact with the server 103 through the network 102 to receive or send messages, etc. The terminal device 101 can be installed with various client applications for receiving push services, such as tutorial applications, recipe applications, video applications, etc.

[0046] The terminal device 101 can be various electronic devices with a display screen and supporting receiving push services, including but not limited to smart phones, tablet computers, e-book readers, MP3 players (Moving Picture Experts Group Audio Layer III, Moving Picture Experts Group Audio Layer IV, Moving Picture Experts Group Audio Layer 4) players, laptop computers and desktop computers, etc.

[0047] The terminal device 101 can be hardware or software. When the terminal device 101 is hardware, it can be various electronic devices. When the terminal device 101 is software, it can be installed in the above electronic devices. It can be implemented as multiple software or software modules (for example, multiple software modules for providing distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0048] The server 103 may be a server that provides various services, for example, a server that provides a tutorial generation service. The server that provides the tutorial generation service may receive a cooking tutorial acquisition request sent by the terminal device 101, and send the generated cooking tutorial to the terminal device 101. For another example, the server 103 may be a server that provides a recipe generation service, and the server that provides the recipe generation service may generate and send a cooking video to the terminal device 101 based on a text recipe sent by the terminal device 101.

[0049] It should be noted that the method for generating an interactive cooking tutorial provided in the embodiments of the present disclosure can be executed by the server 103 or the terminal device 101. Accordingly, the apparatus for generating an interactive cooking tutorial can be arranged in the server 103 or the terminal device 101.

[0050] It should be understood that Figure 1The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.

[0051] Continue to refer Figure 2 , which shows a process 200 of an embodiment of a method for generating an interactive cooking tutorial according to the present application. The method for generating an interactive cooking tutorial is applied to a server, and includes the following steps:

[0052] Step 201: receiving an interactive cooking tutorial creation request, where the interactive cooking tutorial creation request includes a text recipe.

[0053] In this embodiment, the execution subject (eg Figure 1 The server shown in the figure can receive an interactive cooking tutorial creation request via wired or wireless means, and can obtain a text recipe through a terminal device that sends the interactive cooking tutorial creation request, the Internet, or a locally stored knowledge base, wherein the interactive cooking tutorial creation request refers to an instruction or message for creating an interactive cooking tutorial sent by a terminal device to the server.

[0054] Step 202: Analyze the text recipe to determine at least two cooking steps and the timing duration between any two adjacent cooking steps in the at least two cooking steps.

[0055] In this embodiment, the server can determine at least two cooking steps in the text recipe based on the text recipe. The cooking steps refer to the operations, actions or methods of each step in the cooking process, for example, "shred the pork and set aside", "boil over high heat", etc. Specifically, the server can determine at least two cooking steps in the text recipe through a neural network model: the server can first select a standard text recipe and each cooking step of the standard text recipe as training data, train the neural network model, and enable the neural network model to realize the division or determination of the cooking steps in various text recipes; then use the trained neural network model to determine each cooking step of the acquired text recipe.

[0056] In this embodiment, the server can determine the timing duration between two adjacent cooking steps according to the cooking steps of the text recipe based on the neural network model or keyword recognition. It can be understood that the timing duration between two adjacent cooking steps can be the waiting time after the previous step is completed and before the next step is started. For example, the previous step is "low heat and simmer", and the next step is "high heat to collect the sauce", then the timing duration between the two cooking steps is the duration of simmering on low heat after low heat; the timing duration between two adjacent cooking steps can also be the duration of executing the previous step. For example, the previous step is "stir-fry" and the next step is "adding cooking wine", then the timing duration between the two cooking steps is the duration of executing the "stir-fry" action.

[0057] In some application scenarios, when the sending terminal of the interactive cooking tutorial creation request is consistent with the terminal of the user using the interactive cooking tutorial, the server can determine the timing duration between the cooking step and the adjacent subsequent cooking step based on the cooking steps in the text recipe and the eating habits or health status of the user who sent the interactive cooking tutorial creation request. For example, the server can obtain the user's eating habits information or physical health status through the device identification in the interactive cooking tutorial creation request or the user identification information of the small program that sent the interactive cooking tutorial creation request, and extend or shorten the timing duration of the cooking step obtained by keyword recognition. For example, if the user likes softer food or the user is a patient with stomach disease, then after obtaining the timing duration of the cooking step based on the cooking step in the text recipe, the timing duration of cooking steps such as slow cooking, boiling, etc. is appropriately extended, and the extended timing duration is used as the final timing duration between the cooking step and the adjacent subsequent cooking step.

[0058] Step 203, matching a corresponding demonstration video for each of at least two cooking steps.

[0059] In this embodiment, the server can determine the demonstration video corresponding to the cooking step according to the cooking step of the text recipe. The demonstration video refers to an animation demonstration of executing the cooking step, and the demonstration video may be with audio explanation or without audio explanation. The demonstration video may be a demonstration video uploaded by the terminal device and obtained by the server, or a demonstration video searched by the server from the Internet, cloud storage or local knowledge base according to the text recipe.

[0060] Step 204, generating an interactive cooking tutorial based on the timing duration between any two adjacent cooking steps in the at least two steps and the demonstration video corresponding to each cooking step, wherein when the interactive cooking tutorial is triggered for display, for the other cooking steps in the at least two cooking steps except the last cooking step, the cooking step will count down according to the subsequent timing duration after execution.

[0061] In this embodiment, the server splices the demonstration video in the order of the cooking steps, and when splicing, a timing duration is reserved between two adjacent cooking steps. It can be understood that the reserved timing duration is the countdown duration after executing the previous cooking step and before the next cooking step. When the interactive cooking tutorial is sent to the user terminal and triggered by the user, except for the last cooking step, the countdown ends when the reserved duration is played, and the demonstration video corresponding to the next cooking step begins to be played. The purpose of reserving the timing duration is to allow the user to perform corresponding operations according to the cooking tutorial and the time required to execute each cooking step in the cooking tutorial when the user splices the cooking tutorial composed of the demonstration video and the reserved timing duration. And because it is inconvenient for the user to frequently click the terminal device with both hands during the cooking process, the cooking tutorial reserves the time required to execute each cooking step to avoid the user frequently clicking the play button and the pause button, which is convenient for the user to use and improve the user experience.

[0062] This embodiment determines the cooking steps through a text recipe, and determines the timing duration between any two adjacent cooking steps and the demonstration video corresponding to each cooking step based on the cooking steps, and then generates an interactive cooking tutorial based on the timing duration between any two adjacent cooking steps and the demonstration video corresponding to each cooking step. This can help users of the interactive cooking tutorial to grasp the step details and operation time of the cooking steps in the text recipe, thereby improving the success rate of cooking.

[0063] Optionally, the text recipe includes the entire recipe, and the text recipe is analyzed to determine at least two cooking steps and the timing duration between any two adjacent cooking steps of the at least two cooking steps, including: performing semantic analysis on the entire recipe to determine each cooking step included in the entire recipe and the timing duration between any two adjacent cooking steps of each cooking step.

[0064] In this embodiment, when the text recipe is a complete recipe including all steps required to complete the corresponding dish, the server can determine at least two cooking steps in the text recipe and the timing duration between any two adjacent cooking steps through keyword-based semantic analysis.

[0065] Specifically, the cooking steps can be identified based on words such as "cut vegetables, blanch" that describe cooking operations. For example, if a text recipe contains the sentence "First, cut the vegetables, and then blanch the cut vegetables", the two cooking steps of "cut vegetables" and "blanch the cut vegetables" in the text recipe can be determined based on the two words "cut vegetables" and "blanch" that describe cooking operations. The server can identify cooking steps based on logical conjunctions such as "first, then, first step, second step". For example, if a text recipe contains the sentence "first step, peel and cut the potatoes into shreds; second step, rinse with cold water, rinse off the starch and set aside", the two cooking steps of "peel and cut the potatoes into shreds" and "rinse with cold water, rinse off the starch and set aside" in the text recipe can be determined based on the two logical conjunctions "first step, second step".

[0066] Specifically, the server can perform keyword recognition on the cooking steps in the text recipe based on the words describing time or duration in the text recipe, and identify the time required to complete the cooking step. For example, if a cooking step in the text recipe is "slowly simmer for 30 minutes, then add chopped green onions", it can be determined that the time duration between the two cooking steps "slowly simmer" and "add chopped green onions" is 30 minutes.

[0067] Optionally, the text recipe includes multiple segmented recipes and timing duration information between any two adjacent segmented recipes, and the text recipe is analyzed to determine at least two cooking steps and the timing duration between any two adjacent cooking steps of the at least two cooking steps, including: determining at least two cooking steps corresponding to the multiple segmented recipes according to the multiple segmented recipes, and determining the timing duration between any two adjacent cooking steps of the at least two cooking steps according to the timing duration information between any two adjacent segmented recipes.

[0068] In this embodiment, when the text recipe includes a segmented recipe corresponding to each step required to complete the dish corresponding to the text recipe, and the timing duration information between each two adjacent steps, the server can determine each cooking step in the text recipe according to each segmented recipe, and determine the timing duration between two adjacent cooking steps according to the timing duration information. The segmented recipe can be a recipe corresponding to each cooking step in the text recipe uploaded by the user in a preset format, and the timing duration information can be the waiting time after executing the segmented recipe uploaded by the user when uploading the segmented recipe.

[0069] Optionally, matching a corresponding demonstration video for each of the at least two cooking steps includes: for each of the at least two cooking steps, searching a database for a demonstration video corresponding to the cooking step.

[0070] In this embodiment, the server can search for demonstration videos corresponding to the cooking steps in the text recipe by using keywords or the like in a database, knowledge base, or tutorial library stored on the Internet or locally.

[0071] Optionally, the interactive cooking tutorial creation request includes a complete cooking video corresponding to the text recipe, matching a corresponding demonstration video for each of at least two cooking steps, including: segmenting the complete cooking video according to the text recipe to obtain a demonstration video corresponding to each cooking step.

[0072] In this embodiment, a complete cooking video refers to an animated demonstration of a demonstration video of each cooking step in a text recipe. When the interactive cooking tutorial creation request includes a complete cooking video corresponding to a text recipe, the server can segment the cooking video according to the cooking steps in the text recipe to obtain demonstration videos corresponding to the cooking steps in the text recipe. Specifically, the server can identify each frame of the cooking video and determine the demonstration video corresponding to the cooking step in the cooking video based on the picture of the title page or the separator page. For example, if a frame in a cooking video has a title bar "Step 3" in the middle of the picture, this frame can be used as the dividing point between the second step and the third step; the server can identify each frame in the cooking video, and segment the cooking video according to changes in environmental factors or changes in the demonstrator's actions in continuous pictures. For example, the 1st to 100th frames of the cooking video all show scenes of cutting vegetables with a chopping board, and the 101st to 200th frames are scenes of cooking at the stove. The cooking video can be segmented into frames 1 to 100 as demonstration videos corresponding to the cutting steps, and frames 101 to 200 as demonstration videos corresponding to the blanching steps; keyword recognition can also be performed based on the audio data in the cooking video to confirm the time points corresponding to each cooking step, and the cooking video can be segmented according to the time points to obtain demonstration videos corresponding to each cooking step.

[0073] Optionally, the interactive cooking tutorial creation request includes matching a corresponding demonstration video for each of at least two cooking steps, and matching a corresponding demonstration video for each of at least two cooking steps includes: extracting the corresponding demonstration video for each of at least two cooking steps from the interactive cooking tutorial creation request.

[0074] In this embodiment, when the interactive cooking tutorial creation request includes a demonstration video corresponding to each cooking step in the text recipe, the server can obtain the demonstration video corresponding to each cooking step from the interactive cooking tutorial creation request. The demonstration video in the interactive cooking tutorial creation request can be a demonstration video corresponding to each cooking step in the text recipe uploaded in a preset format by the user who sends the interactive cooking tutorial creation request when sending the text recipe.

[0075] Optionally, the interactive cooking tutorial creation request includes demonstration videos of some of the at least two cooking steps, and matches a corresponding demonstration video for each of the at least two cooking steps, including: for each of the at least two cooking steps, in response to finding the demonstration video corresponding to the cooking step in the cooking tutorial creation request, extracting the demonstration video corresponding to the cooking step from the cooking tutorial creation request; or, in response to not finding the demonstration video corresponding to the cooking step in the cooking tutorial creation request, querying the demonstration video corresponding to the cooking step in a database.

[0076] In this embodiment, the interactive cooking tutorial creation request only contains demonstration videos of some cooking steps in the text recipe, so the demonstration video corresponding to each cooking step is first searched in the interactive cooking tutorial creation request. If the corresponding demonstration video is found, the demonstration video is used as the demonstration video corresponding to the cooking step. If the corresponding demonstration video is not found, the demonstration video corresponding to the cooking step is searched in the database.

[0077] In the above Figure 2 In some optional implementations of the described embodiments, the method for generating an interactive cooking tutorial also includes: saving the interactive cooking tutorial in a tutorial library.

[0078] In this embodiment, the generated interactive cooking tutorial can be saved in a tutorial library or database, which can be a local storage space of a server or a cloud storage space. Saving the generated interactive cooking tutorial in a tutorial library or database can directly retrieve the corresponding interactive cooking tutorial from the tutorial library or database when a user requests the same interactive cooking tutorial, thereby avoiding the waste of computing or storage resources caused by repeated tutorial generation, and the generated interactive cooking tutorial can be used as material for a demonstration video.

[0079] In the above Figure 2 In some optional implementations of the described embodiments, the method for generating an interactive cooking tutorial also includes: receiving an interactive cooking tutorial acquisition request sent by a first terminal device, the interactive cooking tutorial acquisition request being used to request an interactive cooking tutorial; and sending the interactive cooking tutorial to the first terminal device.

[0080] In this embodiment, the server can receive an interactive cooking tutorial acquisition request sent by a first terminal device, and then send the corresponding interactive cooking tutorial to the first terminal device, wherein the interactive cooking tutorial acquisition request refers to an instruction or information sent by the terminal device to the server to request an interactive cooking tutorial.

[0081] Optionally, the method for generating an interactive cooking tutorial also includes: receiving a dish rating request sent by a first terminal device, the dish rating request including display information of a dish prepared by a user corresponding to the first terminal device based on the interactive cooking tutorial; determining a first score for the dish based on the display information, and sending the first score to the first terminal device; and / or, sending the display information to a second terminal device, receiving a second score determined based on the display information and sent by the second terminal device, and sending the second score to the first terminal device.

[0082] In this embodiment, the server may receive a dish rating request sent by a user through a first terminal device, wherein the dish rating request includes display information of the dish obtained by the user corresponding to the first terminal device according to the interactive cooking tutorial, and the server determines the first rating of the dish according to the display information, and sends the rating to the first terminal device; or the server sends the obtained display information to the second terminal device, and receives the second rating of the dish sent by the user corresponding to the second terminal device, and sends the second rating to the first terminal device so that the user corresponding to the first terminal device knows the rating of his dish; or the server may also determine the first rating according to the obtained display information, and send the display information to the second terminal device to obtain the second rating, and then send the two ratings to the first terminal device after weighted processing, so that the user corresponding to the first terminal device knows the rating of his dish. Among them, the display information refers to the picture, video or text description of the dish obtained by the user after following the cooking tutorial; the user corresponding to the first terminal device refers to the user who requests the interactive cooking tutorial and cooks according to the interactive cooking tutorial and finally obtains the dish; the user corresponding to the second terminal device refers to the circle of friends, chef, or gourmet, etc. specified by the user corresponding to the first terminal device.

[0083] In this embodiment, the server can compare the picture of the dish completed by the user with the expected picture to obtain the similarity between the two, and determine the score of the dish completed by the user based on the similarity. The server can also collect the text description of the preset questions answered by the corresponding user based on the color, aroma and taste of the finished product through the first terminal device, and determine the score of the dish based on the text description. In this case, the score is more in line with the actual expectations of the user corresponding to the first terminal device for the dish.

[0084] In some application scenarios, the cooking tutorials can also be updated or replaced based on the ratings of the dishes obtained by users using the cooking tutorials. For example, for the same dish, 90% of the users who used cooking tutorial A received a dish rating of 80 points or more on a 100-point scale, while 80% of the users who used cooking tutorial B received a dish rating of less than 30 points on a 100-point scale. In this case, cooking tutorial B may have guidance defects and can be updated or replaced after machine or manual re-inspection.

[0085] This embodiment determines the score of the finished dish based on the display information of the dish completed by the user, which can help the user understand his or her cooking level and degree of improvement, and improve the user's convenience in using recipes.

[0086] Further references Figure 3 , which shows a process 300 of an embodiment of a method for displaying an interactive cooking tutorial according to the present application. The method for displaying an interactive cooking tutorial is applied to a first terminal device, and includes the following steps:

[0087] Step 301, sending an interactive cooking tutorial acquisition request to a server, where the interactive cooking tutorial acquisition request is used to request an interactive cooking tutorial.
