[0040] Example 1

[0041] The embodiment provided in the present disclosure is an embodiment of a problem-solving method.

[0042] like Figure 2As shown, the network teaching system of the embodiment of the present disclosure includes: a server 11, a first client terminal 12 and a second client terminal 13. The first client terminal 12 and the second client terminal 13 are respectively connected to the server 11 for communication. The reviewer reviews through the first client terminal 12. If any questions arise during the review process, the questions are transmitted to the server 11 to seek answers. The Q&A teacher answers the questions through the second client terminal 13. For example, the reviewer logs in to the network teaching system through the first client terminal 12 and enters the main interface of the review mode; in the main interface of the review mode, the reviewer can choose to open the presentation used for review from the presentations used by many teachers when teaching, and enter the secondary interface of the review mode; Figure 3 As shown, the presentation window 21 in the upper left part of the secondary interface displays the presentation image of the presentation, and the note information automatically generated during the lecture is displayed in the lower left part of the secondary interface, wherein the text window 22 in the left half is used to display the recommended text in the note information, and the audio window 23 in the right half is used to display the audio clip in the loaded note information; in the note mode, each note information corresponds to a sentence text in the presentation image, and each sentence text includes a complete semantics; the audio clip comes from the lecture video of the lecturer, including a complete semantics, which is used to explain the sentence text in the presentation image played synchronously; a question window 24 is displayed in the upper right part of the secondary interface, and the question window 24 is used for reviewers to raise questions during the review process; an answer window 25 is displayed in the lower right part of the secondary interface, and the answer window 25 is used to display answer information.

[0043] The presentation refers to a series of static presentation images made into dynamic slides for playback, so as to make the presentation explanation smoother and more vivid, and improve the efficiency of the explanation. For example, a PowerPoint presentation, i.e. a PPT presentation.

[0044] The present disclosure embodiment is applied to the server 11. Figure 1 The embodiments of the present disclosure are described in detail.

[0045] Step S101 : obtaining a first answer request transmitted by a first client terminal 12 .

[0046] The first answer request at least includes question audio.

[0047] The first client terminal 12 is a client terminal used by a reviewer during review.

[0048] When the reviewer encounters a puzzle during the review process, the first client terminal 12 transmits a first answer request to the server 11 .

[0049] The question audio is the audio of the reviewer's question. For example, in the review mode, when the reviewer is watching the presentation document image, he or she may have questions about the image of the sentence text or the audio clip or recommended text in the note information, and then raise the questions through the question audio.

[0050] The problematic audio may be an audio clip obtained in the form of a recording, or may be audio in a recorded video.

[0051] Step S102: perform audio semantic analysis on the question audio to obtain at least two question keywords from the question audio.

[0052] At least two question keywords are obtained to enhance feature information of the question keyword combination, so as to improve the recognition of the question audio represented by the at least two question keywords. The more question keywords there are, the more distinct the semantic features of the represented question audio are.

[0053] In some specific embodiments, performing audio semantic analysis on the question audio to obtain at least two question keywords from the question audio includes the following steps:

[0054] Step S102a: input the question audio into the trained audio semantic analysis model to obtain the at least two question keywords.

[0055] The audio semantic analysis model can be obtained based on previous historical question audio, for example, the audio semantic analysis model is trained using the historical question audio as a training sample. The process of performing audio semantic analysis on the question audio according to the audio semantic analysis model is not described in detail in this embodiment, and can be implemented with reference to various implementation methods in the prior art.

[0056] Of course, other analysis methods may also be used to perform audio semantic analysis on the problematic audio, and the embodiments of the present disclosure do not limit this.

[0057] Step S103: performing a matching search on the knowledge set based on the at least two question keywords to obtain a first search result.

[0058] The knowledge set includes multiple subsets, and the subsets include mutual associations. For example, the knowledge set includes an index subset and an answer information subset; the index subset includes a mapping relationship between at least two question keywords and identification information of the answer information, wherein at least two question keywords are extracted from the question audio; the answer information subset includes a mapping relationship between identification information of the answer information and at least two answer keywords and the answer information; wherein the identification information of the answer information is a self-incrementing sequence value in the answer information subset, and at least two answer keywords are extracted from the answer information; when used, the index subset is matched and searched based on the at least two question keywords, and the search result obtained is the identification information of the answer information; then the answer information subset is searched based on the identification information of the answer information, and the search result obtained is at least two answer keywords and the answer information stored in the answer information subset.

[0059] The auto-increment sequence value of each data record is saved in the auto-increment sequence field of the answer information subset. The auto-increment sequence value in the auto-increment sequence field is a value automatically generated according to the order in which the data records are inserted into the answer information subset. The value can be generated in ascending order or in descending order.

[0060] Step S104: in response to the absence of the first search result, generating a second answer request based at least on the question audio.

[0061] In the database, the first search result does not exist, that is, the first search result is empty, indicating that there is no answer information suitable for the question audio in the server 11, that is, the server 11 cannot automatically obtain the answer information. Then, a second answer request is generated and transmitted to the second client terminal 13.

[0062] The second client terminal 13 is used by the question-answering teacher to manually answer the questions in the received second answer request.

[0063] In some specific embodiments, generating a second answer request based at least on the question audio comprises the following steps:

[0064] Step S104-1, in response to the first answer request also including the sentence text and / or note information corresponding to the question audio, generating a second answer request based on the question audio and the sentence text and / or the note information.

[0065] The image of the sentence text exists in the presentation image played by the first client terminal 12, the sentence text includes a complete semantics, and the note information is related to the sentence text.

[0066] It can be understood that the note information includes at least an audio clip and a recommended text, the audio clip is the audio of the teacher explaining the sentence text in the online teaching video, and the recommended text is the note text automatically recommended for the audio clip.

[0067] For example, if the reviewer has questions about the sentence text, recommended text and / or audio clip in the presentation image, a second answer request is generated based on the question audio and the sentence text, recommended text and / or audio clip, so that the Q&A teacher can clearly understand the context of the question audio based on the question audio and the sentence text, recommended text and / or audio clip, so that the Q&A teacher can accurately answer the question audio.

[0068] Step S105 : transmitting the second answer request to the second client terminal 13 , so as to obtain answer information in response to the second answer request, and transmitting the answer information to the first client terminal 12 .

[0069] The answer information in response to the second answer request includes: answer text, answer audio or answer video.

[0070] When the server 11 of the disclosed embodiment cannot answer the question in the first answer request transmitted by the first client terminal 12, it generates a second answer request and transmits the second answer request to the second client terminal 13 used by the Q&A teacher in a timely manner, so that the Q&A teacher manually answers the question. This reduces the workload of the Q&A teacher, enables the questions raised by the reviewer to be answered in a timely manner, improves the efficiency of Q&A, and also improves the review efficiency of the reviewer.

[0071] After performing a matching search on the knowledge set based on the at least two question keywords and obtaining a first search result, the following steps are further included:

[0072] Step S104a: in response to the existence of the first search result, obtaining answer information included in the first search result and transmitting the answer information to the first client terminal 12 .

[0073] For example, continuing with the above example, the knowledge set includes an index subset and an answer information subset; the index subset includes a mapping relationship between at least two question keywords and identification information of the answer information; the answer information subset includes a mapping relationship between identification information of the answer information and at least two answer keywords and the answer information; when used, a matching search is performed on the index subset based on the at least two question keywords, and the search result obtained is the identification information of the answer information; then the answer information subset is searched based on the identification information of the answer information, and the search result obtained is the answer information stored in the answer information subset; the answer information stored in the answer information subset includes: answer text, answer audio or answer video.

[0074] The server 11 of the disclosed embodiment automatically answers the questions in the first answer request transmitted by the first client terminal 12, thereby reducing the workload of the teacher who answers questions, enabling timely answers to the questions raised by the reviewer, improving the efficiency of answering questions, and also improving the review efficiency of the reviewer.

[0075] Furthermore, after transmitting the second answer request to the second client terminal 13 so as to obtain answer information in response to the second answer request and transmitting it to the first client terminal 12, the following steps are further included:

[0076] Step S111, determining identification information corresponding to the answer information.

[0077] In some specific embodiments, determining the identification information corresponding to the answer information includes the following steps:

[0078] Step S111 - 1 , obtaining at least two answer keywords based on the answer information.

[0079] The answer information includes: answer text, answer audio or answer video.

[0080] When the answer information is an answer text, performing text semantic analysis on the answer text to obtain at least two answer keywords;

[0081] If the answer information is an answer video, obtain the answer audio in the answer video;

[0082] When the answer information is an answer audio, audio semantic analysis is performed on the answer audio to obtain at least two answer keywords.

[0083] Step S111 - 2 : performing a matching search on the at least two answer keywords against the answer information subset of the knowledge set to obtain a second search result.

[0084] The answer information subset includes a self-incrementing sequence field.

[0085] The auto-increment sequence value of each data record is saved in the auto-increment sequence field of the answer information subset. The auto-increment sequence value in the auto-increment sequence field is a value automatically generated according to the order in which the data records are inserted into the answer information subset. The value can be generated in ascending order or in descending order.

[0086] Step S111 - 3 , in response to the absence of the second search result, save the mapping relationship between the at least two answer keywords and the answer information into the answer information subset of the knowledge set, and determine the auto-increment sequence value of the mapping relationship as the identification information.

[0087] When the mapping relationship is saved in the answer information subset of the knowledge set, the auto-increment sequence value of the mapping relationship is automatically generated according to a preset ascending or descending order.

[0088] That is, when the mapping relationship does not have the same data record in the answer information subset of the knowledge set, the mapping relationship is stored in the answer information subset of the knowledge set, and the self-increment sequence value corresponding to the mapping relationship in the answer information subset of the knowledge set is used as the identification information corresponding to the answer information.

[0089] Furthermore, the method further comprises the following steps:

[0090] Step S111 - 4 : in response to the existence of the second search result, determining that the self-incrementing sequence value included in the second search result is identification information corresponding to the answer information.

[0091] That is, when the mapping relationship has the same data record in the answer information subset of the knowledge set, the mapping relationship is not saved in the answer information subset of the knowledge set. Instead, the auto-increment sequence value of the same data record in the answer information subset of the knowledge set is obtained as identification information.

[0092] Step S112: Save the mapping relationship between the at least two question keywords and the identification information corresponding to the answer information into the index subset of the knowledge set.

[0093] The knowledge set of the specific embodiment of the present disclosure includes an index subset and an answer information subset. The index subset only includes the identification information corresponding to the at least two question keywords and the answer information, so that different question keyword combinations can apply the answer information indicated by the same identification information. This improves the flexibility of answering questions, avoids the one-to-one correspondence between keyword combinations and answer information, and reduces data redundancy.
