detailed description

The application will be further described in detail below with reference to the drawings and embodiments. It is understandable that the specific embodiments described here are only used to explain the application, but not to limit the application. In addition, it should be noted that, for ease of description, the drawings only show a part of the structure related to the present application instead of all of the structure.

Example one

FIG. 1 is a flowchart of a method for displaying a courseware page according to Embodiment 1 of the present invention. This embodiment is applicable to a scenario where the target page set is determined from the second page set according to the first page set input by the user, and the target page set is pushed according to the target page set. The method can be executed by a display device of a courseware page, which can be implemented by software and/or hardware, and is usually configured in an electronic device, typically in a processor. Referring to Figure 1, the method may include:

S101. Obtain a courseware.

Courseware is based on the requirements of the teaching syllabus, through the determination of teaching objectives, teaching content and task analysis, teaching activity structure and interface design and other links, and to make course software. It is directly related to the content of the course. Courseware is a course software made with a variety of media expression methods and hypertext structure.

The software for making courseware generally includes PPT and Flash: PPT is powerpoint, a kind of software in the office system. It is similar to the production method of a slideshow, which can import pictures, sounds, animations, videos, type text, get started quickly, have many transition effects, and control the presentation of text and pictures independently. But the screen is a bit dull, and the interactive control is a bit single. Flash was originally an animation software, which can import pictures, sounds, and videos, and input text in the software, and can process and process pictures, videos, and sounds in the software. It is slow to get started and requires certain operating skills. But the screen is flexible and interactive control is flexible.

In a possible implementation, the courseware is composed of multiple courseware pages, and the courseware page is composed of courseware elements. Courseware elements are various elements included in a courseware page. Courseware elements can include: text, formulas, pictures, audio, and video.

In a possible implementation manner, the frequency of recommended courseware is set in the state of editing. It can be understood that when a certain threshold is exceeded, the courseware will be pushed. After the threshold is exceeded, it may be recommended every time a certain amount of pages are edited. As more pages are edited, the accuracy of the recommendation is higher.

In a possible implementation manner, according to the courseware page being edited by the user, other courseware pages related to the courseware page are determined, and these multiple courseware pages are combined into the courseware being edited by the user. The user may open multiple courseware for editing at the same time. You need to distinguish the courseware pages included in different courseware.

S102. Determine a first page set for the courseware.

In a possible implementation, the first page set is an abstract representation of the courseware pages included in the courseware. Generally, the page set is a set of ordered vectors, and the order refers to the order or the reverse order. The order of the collection in the page set is the same as the order of the courseware pages in the courseware, and the vector represents the courseware elements in the courseware page corresponding to this order. The first vector in the first page set indicates the first courseware element in the corresponding first courseware page. The first page set and the subsequent second page set in this step are both sets composed of ordered vectors, which are divided into the first page set and the second page set due to different application scenarios.

In a possible implementation manner, a vector is used to represent the semantic information of the page elements of the corresponding courseware page (sequence).

For each courseware page, you can perform at least one of the following processing:

Directly perform vector processing on text; directly convert formulas into semi-structured strings, perform vector processing on strings; perform image recognition on pictures to obtain text describing the content of the picture, perform vector processing on text; perform voice recognition on audio, Obtain the text content corresponding to the audio and perform vector processing on the text; intercept the key frame images of the video at a preset time interval, perform image recognition on the key frame images, obtain text describing the content of the picture, perform vector processing on the text, and so on.

S103. Obtain a second page set.

In a possible implementation, the second page set is a preset ordered vector set.

The second vector in the second page set indicates the second courseware element in the corresponding second courseware page. In a possible implementation, the courseware pages in the prepared courseware are converted into vectors in advance to form the second page set.

The courseware is usually some excellent courseware. The main source of excellent courseware: organize teachers to prepare; teachers upload and evaluate it as excellent courseware. Store these excellent courseware in the second page set, decompose all the courseware in the second page set into single pages, and mark them in sequence. For example, the first courseware has 8 pages, numbered as 1, 2, 3,..., 8 in the order of each page in the courseware; the second courseware has 9 pages, in the order of each page in the document The numbers are 9, 10, 11,..., 17, and so on to all courseware. Of course, if the first courseware has 8 pages, number them in the order of each page in the courseware as 1-1, 1-2, 1-3,..., 1-8; the second courseware has 9 pages, numbered 2-1, 2-1, ... 2-9 in the order of each of the files, and so on to all courseware. In a possible implementation manner, the courseware in the second page set can be preprocessed, such as deleting the ending "Thank you for watching", "Please ask questions" and other general materials.

S104: Determine a target page set in the second page set.

In a possible implementation, several consecutive second vectors are selected from the second page set as the target vector. Of course, the condition of the selection is that the first vector and the target vector are similar.

In a possible implementation, the number of the first vector and the target vector are the same. At this time, the first vector and the target vector are compared one by one in order to obtain the similarity between each two vectors. When each similarity exceeds a certain threshold, it is considered that the first vector and the target vector are different Similar to each other. Of course, the similarity can also be averaged, and when the average value exceeds a certain threshold, it is considered that the first vector and the target vector are similar. Of course, it is also possible to compare the whole formed by the first vector with the whole formed by the target vector to obtain the overall similarity. When the overall similarity exceeds a certain threshold, it is considered that the first vector and the target vector are similar.

In a possible implementation, the number of the first vector and the target vector are different. The whole formed by the first vector can be compared with the whole formed by the target vector to obtain the overall similarity. When the overall similarity exceeds a certain threshold, the first vector and the target vector are considered to be similar.

S105. According to the target page set, display a part of the second courseware page for the courseware.

The target page set is a part of the coherent courseware pages in the second page set. When the target page set is determined, it indicates that the user is making courseware similar to the courseware corresponding to the target page set. Therefore, one or more courseware pages after the target page set are pushed to the user for display.

In a possible implementation manner, one or more courseware pages after the target page set can be judged as a courseware. When the target page set and one or more courseware pages after the target page set belong to the same courseware, Then one or more courseware pages after the target page set are pushed to the user for display.

In this application, a courseware is obtained; a first page set is determined for the courseware; a second page set is obtained; a target page set is determined in the second page set, and the target page set includes an ordered target vector. A vector is similar to the target vector; according to the target page set, a part of the second courseware page is displayed for the courseware. Realize the push of related courseware pages based on the courseware page made by the current teacher. Such push can predict the content of the next courseware page made by the teacher. The teacher can directly select the courseware elements from the pushed page, thereby reducing the number of courseware produced by the teacher Time spent searching online for courseware elements and typing text.

Example two

Fig. 2A is a flowchart of a method for displaying a courseware page according to the second embodiment of the present invention. This embodiment is a refinement based on the first embodiment, and describes in detail the method of determining the first page set for the courseware and determining the target page set in the second page set. Referring to FIG. 2A, the method may include:

S201. Obtain a courseware.

Get the courseware that the user is editing.

In a possible implementation manner, if the user opens multiple courseware, the multiple courseware is acquired.

In a possible implementation manner, the acquisition operation is performed for the courseware for which the user initiates the push instruction only when the user sends the push instruction.

S202: Determine the first courseware element contained in each first courseware page in the courseware.

The first courseware page is the courseware page included in the courseware obtained in step S201. At this time, the first courseware element can be used to represent the content of the first courseware page.

The first courseware page and the second courseware page are both courseware pages. For ease of description, the courseware page obtained from the user terminal is named the first courseware page, and the courseware page in the second page set used for push/matching is named The second courseware page.

In a possible implementation manner, in order to reduce the requirements for computer performance, text, formulas, and pictures may be determined as the first courseware elements only from the first courseware page.

S203: Convert the first courseware element into a character string.

The first courseware element includes different types, so the first courseware element needs to be unified into one form of expression. At this time, a string can be used to represent the content of the first courseware page.

In a possible implementation, the first courseware element is converted into a character element. If the first courseware element is text, the text is directly determined as a string; if the first courseware element is a formula, the formula will be converted to a string according to the specified typesetting; if the first courseware element is a picture, it will be recognized by image The technology converts the image into text, and then determines the text as a string. This method can have the same evaluation standard for the content of the course page, making this method more practical.

Among them, for formulas, formula editors and Latex format are generally used, so formulas can be directly converted into Latex semi-structured strings. Such as statistical formula:

Turn to: \frac{n! }{r! (nr)! }. Such as chemical equation:

Turn to: 2H_2+O_2\xrightarrow{n,m}2H_2O.

S204. Convert the character string into a first vector.

At this time, the first vector can be used to represent the content of the first courseware page. At present, the first courseware elements that portray the first courseware page are all in the form of strings. All strings in a courseware page are unified into vector elements, and the vector elements are named the first vector. The first vector and the subsequent second vector here are all vector elements describing one page of courseware pages, and they are distinguished in naming for ease of description.

In a possible implementation manner, the character string is input into a BERT (Bidirectional Encoder Representation from Transformers) model to extract the semantic features of the character string. The extracted semantic feature is the first vector here.

S205: Associate the first vector according to the order of the first courseware page in the courseware.

Since the first vector is used to describe the first courseware page in the courseware, the first vector is associated according to the order of the first courseware page in the courseware, so that the first vector is combined into an ordered vector string. The order vector is used to improve the accuracy of course page push. If an unordered vector is used, even if the course page is determined in the second page set, the purpose of predicting the next courseware page of the teacher cannot be fulfilled.

S206. Obtain a second page set.

S207. Determine the similarity between the first candidate vector and the second candidate vector.

S208: Determine whether the similarity is greater than a preset threshold. If yes, go to step S209; if not, go to step S211.

S209: Determine whether there is a remaining first vector after the first candidate vector. If yes, go to step S210; if not, go to step S212.

S210. Set a first vector located in the first candidate vector as a new first candidate vector, and set a second vector located in the second candidate vector as a new second candidate vector. And return to step S207.

S211. Select a new second vector as a new second candidate vector. And return to step S207.

S212. Determine all second candidate vectors as target vectors.

In a possible implementation manner, the first first vector in the first page set is determined as the first candidate vector. A certain vector in the second page set is determined as a second candidate vector, and the second candidate vector is a second vector compared with the first candidate vector. Compare the similarity between the first candidate vector and the second candidate vector.

If the similarity is greater than the preset threshold, it means that the first courseware page represented by the first candidate vector is similar to the second courseware page represented by the second candidate vector. At this time, continue to compare the next first vector of the first candidate vector in the first page set with the next second vector of the second candidate vector in the second page set. For ease of description, the next first vector of the first candidate vector in the first page set is determined as the first candidate vector, and the next second vector of the second candidate vector in the second page set is determined as the second candidate vector, Continue to compare. If the similarity is less than the preset threshold in the subsequent comparison, the new second candidate vector is determined again, and the first page set is compared from the beginning. If there is no situation in which the similarity is less than the preset threshold in the subsequent comparison, it is determined that all the second candidate vectors are target vectors.

If the similarity is less than the preset threshold, it means that the first courseware page represented by the first candidate vector is not similar to the second courseware page represented by the second candidate vector. Take the second vector next to the second candidate vector in the second page set as the new second candidate vector. Continue to compare.

Generally, the cosine similarity is used to determine the similarity between two vectors, that is, the cosine of the angle between the two vectors is calculated to evaluate their similarity.

S213: According to the target page set, display a part of the second courseware page for the courseware.

In a possible implementation manner, according to the determined target page set, the second courseware page in the second page set corresponding to the target page set is displayed, so as to facilitate the user to learn from the format or layout.

In a possible implementation manner, according to the determined target page set, subsequent second courseware pages in the second page set corresponding to the target page set are displayed, so as to save the user's time for inputting subsequent content.

Based on the foregoing embodiment, FIG. 2B is a flowchart of a method for displaying a software page according to a user attribute course according to the second embodiment of the present invention. Referring to Figure 2B, the method includes:

S220. Determine the first user attribute of the first user and the first behavior data of the operating courseware; S221. Convert the first user attribute and the first behavior data into first user characteristics; S222. Acquire second user characteristics , The second user characteristic is used to characterize the second user attribute of the second user and the second behavior data of the operating courseware; S223, if the first user characteristic is similar to the second user characteristic, display the first user characteristic 2. The user's courseware.

In a possible implementation manner, the first user and the second user are both users, the first user is a user who is editing courseware, and the second user is a user stored in a database. User attributes are the basic information that the user will register before using the electronic courseware production software for the first time, including information such as subject, school period, age, and gender. The first user information is the user information of the user who is editing the courseware, and the second user information is the user information of the user stored in the database. Behavioral data is the data generated by the user's operations, including button clicks, menu selection, editing content, stay time, etc. Combining these characteristics, the user's preferences can be predicted through the machine learning classification model. Preferences are mainly divided into two categories: one is the content of the courseware, including text, voice, video, pictures, tables, animations, games, etc., which form part of the content of the courseware; the other is the style of the courseware, such as colors, fonts, elements, shapes, Typesetting, etc.

In a possible implementation manner, the similarity of user attributes and behavior data between the first user and the second user is calculated, and if the similarity is high, the material of the second user is being recommended to the first user. If the first user is a user who is an English major and who likes materials with a light style, the materials of the second user with high similarity are directly recommended to the first user. This second user may also be an English subject or also like a light style.

Example three

FIG. 3 is a flowchart of a method for constructing a page set according to Embodiment 3 of the present invention. This embodiment is applicable to a scenario where an ordered vector is generated according to the acquired pages, and the ordered vector is used to construct a page set. The method can be executed by a device for constructing a page set, which can be implemented by software and/or hardware, and is usually configured in an electronic device, typically in a processor. Referring to Figure 3, the method may include:

S301. Obtain the courseware.

The courseware includes the courseware page.

In a possible implementation, the excellent courseware constitutes the second page set. The main sources of excellent courseware: organize the preparation of famous teachers from famous schools; teachers upload and evaluate them as excellent courseware.

S302. Generate a page set.

The page set contains ordered vectors, and each vector is used to represent the semantics of the courseware elements in each courseware page.

In a possible implementation manner, a vector is used to represent the semantic information of the page element of the courseware page. It can be understood as: direct vector processing of text; direct conversion of formulas into semi-structured strings and vector processing of strings; image recognition of pictures to obtain text describing the content of the picture, and vector processing of text; audio Perform voice recognition to obtain the text content corresponding to the audio, and perform vector processing on the text; intercept key frame images of the video at preset time intervals, perform image recognition on the key frame images, obtain text describing the content of the picture, and perform vector processing on the text .

In a possible implementation manner, these excellent courseware are stored in a page set, and all the courseware in the page set are decomposed into single pages and marked in sequence. For example, the first courseware has 8 pages, numbered as 1, 2, 3,..., 8 in the order of each page in the courseware; the second courseware has 9 pages, in the order of each page in the document The numbers are 9, 10, 11,..., 17, and so on to all courseware. Of course, if the first courseware has 8 pages, number them in the order of each page in the courseware as 1-1, 1-2, 1-3,..., 1-8; the second courseware has 9 pages, numbered 2-1, 2-1, ... 2-9 in the order of each of the files, and so on to all courseware. In a possible implementation manner, the courseware in the second page set can be preprocessed, such as deleting the ending "Thank you for watching", "Please ask questions" and other general materials.

Example four

FIG. 4 is a flowchart of a method for constructing a page set according to Embodiment 4 of the present invention. This embodiment is refined on the basis of the third embodiment, and describes in detail the method of generating the page set. Referring to Figure 4, the method may include:

S401. Obtain courseware.

S402: Convert the courseware elements contained in the courseware page into vectors.

In a possible implementation manner, first determine the courseware elements included in the courseware page. In order to reduce the requirements for computer performance, only text, formulas and pictures can be determined from the courseware page as the courseware elements. Since the courseware elements include different types, it is necessary to unify the courseware elements into one form of expression. At this time, you can use a string to represent the content of the courseware page. Then convert the string to a vector.

In a possible implementation, the first courseware element is converted into a character element. If the first courseware element is text, the text is directly determined as a string; if the first courseware element is a formula, the formula will be converted to a string according to the specified typesetting; if the first courseware element is a picture, it will be recognized by image The technology converts the image into text, and then determines the text as a string.

S403: Associate vectors belonging to the same courseware according to the order of the courseware pages in the courseware.

Since vectors are used to describe the courseware pages in the courseware, according to the order of the courseware pages in the courseware, the vectors are associated, so that the vectors are combined into an ordered vector string.

S404: According to the order of the courseware, associate the vectors corresponding to the courseware.

Since the page set includes multiple courseware, there is also a sequential relationship between the courseware and the courseware. The vector numbering can refer to the way of numbering pages in step S302.
