[0022] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] Figure 1 This is a flowchart illustrating a question-answering method provided in an embodiment of the present disclosure. This method can be executed by a question-answering device, which can be implemented using software and / or hardware, and is generally integrated into an electronic device. Figure 1 As shown, the method mainly includes the following steps S102 to S108:

[0024] Step S102: In response to the user's request for draft calculation for the target problem, display the draft page.

[0025] This disclosure does not limit the type of the target question. For example, the target question can be a subjective question or a multiple-choice question. Furthermore, the target question can be a question displayed to the user during the playback of the target video, such as a question appearing in an instructional video that requires the user to provide an answer; the target question can also be a question in the electronic test paper currently being answered by the user. In this disclosure, a trigger button can be provided on the interface for the user to initiate a draft calculation request. When the trigger button is detected to have been triggered by the user (e.g., clicked), it is confirmed that the user has initiated a draft calculation request for the target question, thereby displaying the draft page. The target question is the question corresponding to the user's draft calculation request; specifically, the target question can be the question currently displayed on the interface when the user initiates the draft calculation request.

[0026] This disclosure does not limit the display format of the draft page. For example, the draft page can be displayed on the current interface with a preset transparency. Users can write directly on the draft page and also view the information of the target problem on the current interface. The current interface will not be obscured by the draft page with a certain transparency, which makes it convenient for users to perform draft calculations while looking at the problem.

[0027] Step S104: Obtain the writing trajectory of the user on the draft page and save the target trajectory in the writing trajectory.

[0028] For example, users can write on the draft page using their fingers or a stylus; this embodiment does not restrict the user's writing method. In practical applications, the user's writing trajectory on the draft page can be acquired in real time or at specified intervals, and the target trajectory within the writing trajectory can be saved. The target trajectory can be a part of the writing trajectory or the entire trajectory, which can be flexibly set according to needs. For example, the target trajectory is the trajectory within the last specified time period of the writing trajectory. It is understood that, typically, the draft calculation results are located at the end of the writing trajectory. Through the above method, storage costs can be effectively saved.

[0029] Step S106: When the user exits the draft page, identify the key characters of the saved target trajectory, and determine the draft calculation result of the target question based on the identified key characters.

[0030] In practical applications, a trigger button can be provided for users to exit the draft page. By triggering this button, users can exit the draft page, indicating that they have completed the draft calculations. At this point, the user's draft calculation result can be obtained based on the saved target trajectory. For example, the target trajectory can be converted into an image, and the characters represented by the trajectory in the image can be identified using OCR (optical character recognition). A string parsing algorithm can then be used to parse the string corresponding to the target trajectory. For instance, the string "8+2=10" can be parsed into five characters: 8, +, 2, =, and 10. Furthermore, preset key characters can be identified from the parsing results. These key characters are pre-set characters that help identify the draft calculation result from the string. This embodiment does not limit the specific type of key characters; for example, if the target problem is a math problem, the key character would be the equals sign. Through this method, the draft calculation result can be quickly and reliably determined from the target trajectory by identifying key characters. In addition, if no key characters are identified in the target trajectory, no further processing will be performed, and the system will wait for the user to fill in the answer.

[0031] Step S108: Based on the calculation results of the draft, perform the answer filling operation for the target question.

[0032] Compared to related technologies that require users to manually fill in the answers, this embodiment can automatically fill in the answers by recognizing the obtained draft calculation results, eliminating the need for users to fill in the answers separately and significantly improving the convenience of answering questions. In practical applications, the answer filling operation can vary depending on the type of the target question. For example, if the target question is a subjective question, the draft calculation results can be directly filled in the area to be answered; while if the target question is an objective question, the answer can be selected from multiple options provided by the target question based on the draft calculation results. The above are merely examples and are not intended to be limiting.

[0033] In summary, the technical solutions provided in this embodiment not only allow users to perform draft calculations online directly through the draft page without needing to prepare paper and pen or switch between online and offline scenarios, but also accurately and reliably identify the draft calculation results based on key characters in the user's writing trajectory and automatically fill in the corresponding answers to the questions based on the draft calculation results, eliminating the need for users to manually fill in the answers based on the draft calculation results. Therefore, this makes the question-answering process more convenient for users, effectively improves the efficiency of question answering, and ensures that users have a good online question-answering experience.

[0034] Furthermore, this disclosure provides a specific implementation of step S104 above, namely, obtaining the user's writing trajectory on the draft page and saving the target trajectory in the writing trajectory. For example, it can be performed with reference to the following steps (1) and (2):

[0035] Step (1) reads the user's writing trajectory on the draft page at preset time intervals. In practical applications, a timer can be used to read the user's writing trajectory (also known as draft trajectory data) once the preset time interval is reached. This embodiment does not limit the time interval; for example, the writing trajectory can be read every 1 second using a timer. In this way, the user's writing trajectory can be recorded more efficiently and reliably.

[0036] Step (2) involves performing a save operation on each read writing trajectory until the user exits the draft page. The save operation saves the target trajectory within the last specified time period from the read writing trajectory, and the target trajectory saved in subsequent save operations overwrites the target trajectory saved in the previous save operation. "Overwrite" means deleting the target trajectory saved in the previous save operation and retaining only the target trajectory saved in the previous save operation. This embodiment does not limit the specified time period; for example, the specified time period can be 10 seconds. That is, the above method always saves the last 10 seconds of writing trajectory and overwrites the result of the previous save in the local cache. Specifically, the trajectory (target trajectory) of the last 10 seconds of the read writing trajectory is saved in the local cache each time. For example, the user's writing trajectory on the draft page is read every 1 second. The writing trajectory from the first 1 to the 10th second is saved first. After the writing trajectory is read in the 11th second, the writing trajectory from the 2nd to the 11th second is overwritten with the writing trajectory from the 1st to the 10th second. After the writing trajectory is read in the 12th second, the writing trajectory from the 3rd to the 12th second is overwritten with the writing trajectory from the 2nd to the 11th second, and so on, until the user exits the draft page. At this point, the writing trajectory of the last 10 seconds is finally saved. For example, if the user writes on the draft page for a total of 50 seconds, only the writing trajectory from the 41st to the 50th second is saved. The finally saved trajectory is the target trajectory.

[0037] For easier understanding, please refer to the following: Figure 2 The diagram illustrates a trajectory saving process, showing how draft trajectory data (i.e., writing data) is retrieved at preset time intervals (e.g., 1 second), with the last 10 seconds of draft trajectory data stored in a local cache each time. It should be noted that... Figure 2The diagram simply illustrates two 10-second intervals, but the draft trajectory data corresponding to the two 10-second intervals are not input to the local cache simultaneously. Instead, they are saved to the local cache sequentially through a timer. The draft trajectory data corresponding to the latter 10 seconds will overwrite the draft trajectory data corresponding to the former 10 seconds. For example, the data from the 2nd to the 11th seconds will overwrite the data from the 1st to the 10th seconds.

[0038] By using the above method, it can be ensured that the local cache always stores the trajectory of the last specified duration in the currently obtained writing trajectory. This ensures that the final draft calculation result can be obtained, while also fully conserving the storage resources of the local cache.

[0039] Furthermore, this disclosure provides a specific implementation of the step S106 above, which involves determining the draft calculation result of the target question based on the identified key characters. For example, it can be performed with reference to steps a and b below:

[0040] Step a: In the saved target trajectory, obtain the associated content of the identified key characters.

[0041] As mentioned earlier, the target trajectory can be converted into an image, and image recognition can be performed using OCR technology to obtain the string in the target trajectory and find key characters. This embodiment of the disclosure can further obtain the draft calculation results through key characters, which is more convenient and faster. In specific implementation, the associated content of the key characters can be obtained first. In some implementation examples, the associated content includes the content following the key character. Taking the equals sign as an example, all characters after the equals sign are considered as associated content.

[0042] When multiple key characters are identified, the associated content of the last key character is obtained according to the order in which they appear in the saved target trajectory. For example, if multiple equal signs appear during the user's draft calculation, the character after the last equal sign is obtained, thus ensuring that the user's draft calculation result can be accurately obtained.

[0043] Step b: Based on the associated content, obtain the draft calculation result of the target question. For example, the associated content can be directly used as the draft calculation result.

[0044] For easier understanding, please refer to the following: Figure 3The diagram illustrates one method of obtaining a result. It shows how a draft image can be generated from the target trajectory in the local cache. The draft image simply represents "8+2=10". Then, OCR technology is used to recognize the characters in the draft image to obtain a draft string. This draft string is a whole, so it can be parsed and broken down into individual characters. For example, the string "8+2=10" can be parsed into five characters: 8, +, 2, =, and 10. By finding the key character "=", the characters before "=" are ignored, and the character "10" after "=" is taken as the obtained draft calculation result. It should be noted that... Figure 3 This is just a simplified illustration. In practical applications, if multiple "=" signs are detected, only the content after the last equal sign will be taken to ensure that the final result is the draft calculation result, not the intermediate result.

[0045] This disclosure provides a specific implementation method for step S108 above, that is, performing the answer filling operation for the target question based on the draft calculation result. For example, it can be performed by referring to the following steps A and B:

[0046] Step A: Obtain the question type of the target question. For example, the question type may include multiple-choice questions and subjective questions.

[0047] Step B involves filling in the answers to the target questions based on the draft calculation results and the question type. It's understood that different question types require different answer-filling methods. For example, the question types are categorized into subjective and objective questions, and the following two methods are provided for each:

[0048] Method 1: When the question type is subjective, fill in the draft calculation results in the answer area of ​​the target question. For example, if the target question is a subjective fill-in-the-blank question, the draft calculation results can be automatically filled in the blank area of ​​the fill-in-the-blank question.

[0049] Method 2: In the case of objective questions, multiple options for the target question can be obtained first; then, the target option that matches the draft calculation result can be found from the multiple options; if the target option is found, it can be marked as the answer to the target question according to a preset method. It is understood that objective questions usually provide users with multiple options for them to select the correct one. In this embodiment, the user's draft calculation result can be directly compared with the current multiple options to find the target option that matches the draft calculation result, and the target option can be marked as the answer to the target question according to a preset method. This embodiment does not limit the preset method; for example, the preset method may include one or more of the following: filling the identifier of the target option into the answer area of ​​the target question, highlighting the target option, checking the target option, or adding an underline under the target option. In this way, the user can quickly mark the option they believe to be correct based on their draft calculation result without any further comparison by the user.

[0050] If no target option is found, the draft calculation results can be displayed as a floating window on the current page to remind the user to select the answer to the target question from multiple options based on the draft calculation results. In other words, if the user's draft calculation results do not match any of the options, it indicates that there may be a problem with the user's draft calculation process. In this case, the draft calculation results can be displayed as a floating window on the current page, and the transparency of the draft calculation results can be adjusted so that the user can view the draft calculation results and multiple options simultaneously, assisting the user in thinking. The user can choose the target option based on the draft calculation results, or they can re-initiate the draft calculation request and be shown the draft page again so that they can recalculate on the draft page.

[0051] In summary, the above method automatically fills in the answers based on the draft calculation results, eliminating the need for users to manually fill them in. This makes the question-answering process more convenient and effectively improves the user's efficiency. Furthermore, it should be noted that this embodiment also supports user modification of the automatically filled answers. For example, users can delete the answers entered into the answer area through the above-described answer filling operation and manually re-enter the answers, ensuring that the filled answers fully meet the user's needs.

[0052] Based on the foregoing, the embodiments disclosed herein further provide, as follows: Figure 4 The flowchart shown illustrates one method for answering questions, which mainly includes the following steps:

[0053] Step S402: Play the video for the user to watch online. This video may be an instructional video.

[0054] Step S404: In response to receiving a user's request for draft calculation of the target problem in the video, a draft page is displayed for the user to write on. It is understandable that teaching videos may include interactive or assessment segments, which will display problems for students to solve. Students can then use the draft function to perform online calculations on the problem to be solved (the target problem).

[0055] Step S406: The local system caches the user's writing trajectory at any time after the last specified period. For example, it may cache the user's writing trajectory in the last 10 seconds; there is no limit to this.

[0056] Step S408: Determine if the user has exited the draft page. If not, return to step S406; if yes, proceed to step S410.

[0057] Step S410: Extract local cache.

[0058] Step S412: Perform OCR recognition based on the writing trajectory extracted from the local cache.

[0059] Step S414: Determine if an equal sign has been recognized. If not, end the process, and the user can then manually fill in the answer; if yes, proceed to step S416.

[0060] Step S416: Extract the content after the last equal sign that has been identified, and use it as the draft calculation result.

[0061] Step S418: Determine whether the target question is an objective question or a subjective question. If it is an objective question, proceed to step S420; if it is a subjective question, proceed to step S428: fill in the draft calculation results in the unanswered area of ​​the target question.

[0062] Step S420: Compare the draft calculation results with each of the multiple options.

[0063] Step S422: Determine whether a target option matching the draft calculation result has been found. If yes, proceed to step S424; otherwise, proceed to step S426.

[0064] Step S424: Mark the target options as answers to the target question according to a preset method. The preset method can be, for example, highlighting or checking, and is not limited here.

[0065] Step S426: Display the draft calculation results on the current page in the form of a floating window to assist the user in making selections.

[0066] In summary, the above methods allow users to perform draft calculations directly online via the draft page, eliminating the need for paper and pen or switching between online and offline scenarios. Furthermore, only the last specified duration of the writing process is saved, effectively conserving memory resources while ensuring the availability of draft calculation results. Additionally, the equals sign in the user's writing path accurately and reliably identifies the draft calculation results and automatically fills in the corresponding answers based on the results and question type, eliminating the need for users to manually input answers from the draft calculations. Therefore, this makes the question-answering process more convenient, effectively improving user efficiency and ensuring a positive online question-answering experience.

[0067] Corresponding to the aforementioned question-answering method, this disclosure also provides a question-answering device.
