Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, electronic device and storage medium for typesetting handouts. Background Art

[0002] With the expansion and penetration of Internet technology into the field of education, online education platforms have emerged one after another. In the online education scenario, teachers use online handouts to compile learning courseware. The typesetting and printing process of online handouts can be to export the handouts as Word files, and then import the Word files into offline typesetting software for secondary editing, and then obtain the edited learning courseware.

[0003] However, due to the format differences between online handouts and Word files, formatting errors are inevitable when exporting handouts as Word files. In addition, due to the incompatibility issues between Word files and typesetting software, the final edited courseware has many losses and errors in content and style. Summary of the invention

[0004] The embodiments of the present disclosure at least provide a method, device, electronic device and storage medium for typesetting handouts.

[0005] In a first aspect, an embodiment of the present disclosure provides a method for typesetting a lecture note, the method comprising:

[0006] Obtaining a handout file in a first document format to be typeset;

[0007] Based on a standard content model, the lecture file is standardized to obtain a standard file; the standard content model is used to uniformly describe the content and style of rich text documents in different document formats;

[0008] Based on the standard file and the target typesetting system configuration information, a target typesetting system file is obtained;

[0009] The target typesetting system file is typeset to generate a lecture file in a typeset second document format.

[0010] By adopting the above-mentioned lecture notes typesetting method, the lecture notes files to be typeset can first be standardized based on the standard content model to obtain standard files. Since the standard content model here is used to uniformly describe the content and style of rich text documents under different document formats, the standard files generated based on the above-mentioned standard content model can well take into account the lecture notes files and the typesetting system files, ensuring the compatibility between the target typesetting system files generated by the subsequent configuration of the standard files based on the target typesetting system configuration information and the typesetting system, thereby reducing the probability of loss and errors in the typesetting content and making the typesetting accuracy higher.

[0011] In a possible implementation, the standardization process of the lecture file based on the standard content model to obtain a standard file includes:

[0012] Parsing the lecture file based on a predefined file parsing model to parse out first file data information matching the file parsing model;

[0013] Determine a parsed file according to the parsed first file data information and the file parsing model;

[0014] Converting the parsed file based on a predefined standard content model to obtain second file data information matching the standard content model;

[0015] The standard file is obtained based on the obtained second file data information and the standard content model.

[0016] Here, considering the problem of poor readability of the data structure of the lecture file, we can first parse it based on the file parsing model, and then convert the parsed file based on the standard content model, so as to obtain the second file data information matching the standard content model, and then obtain the standard file, realizing the conversion from lecture file to standard file, which is more practical.

[0017] In a possible implementation, the target typesetting system file includes a LaTeX file, and obtaining the target typesetting system file based on the standard file and the target typesetting system configuration information includes:

[0018] Reading each paragraph of the standard file in sequence; each paragraph includes at least one block;

[0019] For each block in each of the paragraphs read, perform attribute analysis on the block based on a preset attribute analyzer to determine the attribute of the block;

[0020] Based on the preset correspondence between each attribute and each LaTeX command, determine the LaTeX command matching the attribute of each block;

[0021] Based on the LaTeX commands that match the properties of each block, a LaTeX file is obtained.

[0022] Considering the excellent characteristics of LaTeX files at the typesetting level, the target typesetting system files here may include LaTeX files. Here, the properties of the blocks can be determined based on the property analysis results of each block in each paragraph of the standard file, and then the LaTeX commands that match the properties of each block are determined based on the preset correspondence between the properties and the LaTeX commands. In this way, LaTeX files can be obtained based on the LaTeX command configuration, and the obtained LaTeX files can be better compatible with subsequent LaTeX typesetting systems. In addition, here is the LaTeX command corresponding to the property matching of the block, and the modification of the LaTeX command can be realized later to achieve unified modification of the properties, thereby improving the subsequent typesetting efficiency.

[0023] In a possible implementation, obtaining a LaTeX file based on a LaTeX command matching the attributes of each block includes:

[0024] For each block in each of the paragraphs, a LaTeX command matching the attribute of the block and the content of the block are bound to obtain a LaTeX command line corresponding to the block;

[0025] For each of the paragraphs, combining the LaTeX command lines corresponding to the blocks belonging to the paragraph to obtain a LaTeX command line corresponding to the paragraph;

[0026] The LaTeX command lines corresponding to the paragraphs are combined according to the arrangement order of the paragraphs to obtain a LaTeX file.

[0027] Here, the properties of the blocks and the contents of the blocks are bound to obtain the LaTeX command line corresponding to each paragraph, and the final LaTeX file can be obtained by combining the paragraphs. For LaTeX files, the properties of the blocks can be modified separately, and the contents of the blocks can also be modified separately, which improves the efficiency of subsequent typesetting.

[0028] In a possible implementation manner, the lecture file in the second document format includes a PDF file, and typeset the target typesetting system file to generate the typeset lecture file in the second document format, including:

[0029] When it is determined that an editing instruction for the LaTeX file is received from the client, modifying the LaTeX file based on the editing instruction to obtain a modified LaTeX file;

[0030] The modified LaTeX file is typeset to generate a typeset PDF file.

[0031] In a possible implementation, the LaTeX command includes a macro command; receiving an editing instruction from a client for the LaTeX file includes:

[0032] Receiving a style editing instruction of a macro command matching an attribute of any block included in the LaTeX file;

[0033] Alternatively, a content editing instruction for any block included in the LaTeX file is received.

[0034] Here, style editing can be implemented through style editing instructions of macro commands that match block attributes, and content editing can also be implemented through content editing instructions of blocks, supporting various editing requirements.

[0035] In a possible implementation, typeset the target typesetting system file to generate a typeset lecture file in the second document format, including:

[0036] The target typesetting system file is typeset by calling a preset typesetting engine to generate a lecture file in a typeset second document format.

[0037] In a possible implementation manner, after obtaining the standard file for describing each file format, the method further includes:

[0038] When it is determined that a conversion instruction pointing from the target typesetting system file to other target typesetting system files is received, a standard file corresponding to the target typesetting system file is obtained, and other typesetting system files are obtained based on the standard file and other typesetting system configuration information.

[0039] Here, considering that standard files can accommodate various document formats, arbitrary conversion between target typesetting system files and other typesetting system files can be achieved based on standard files, which has better adaptability.

[0040] In a second aspect, an embodiment of the present disclosure further provides a device for typesetting a lecture note, the device comprising:

[0041] An acquisition module, used for acquiring a handout file in a first document format to be typeset;

[0042] A first generation module is used to standardize the lecture file based on a standard content model to obtain a standard file; the standard content model is used to uniformly describe the content and style of rich text documents in different document formats;

[0044] The typesetting module is used to typeset the target typesetting system file and generate a lecture file in a typeset second document format.

[0045] In the third aspect, an embodiment of the present disclosure further provides an electronic device, comprising: a processor, a memory and a bus, wherein the memory stores machine-readable instructions executable by the processor, and when the electronic device is running, the processor and the memory communicate via the bus, and when the machine-readable instructions are executed by the processor, the steps of the method for typesetting lecture notes as described in the first aspect and any of its various embodiments are performed.

[0046] In a fourth aspect, an embodiment of the present disclosure further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, executes the steps of the method for typesetting lecture notes as described in the first aspect and any of its various embodiments.

For example, including at least one of A, B, and C may represent including any one or more elements selected from the set consisting of A, B, and C.

[0057] Research has found that due to the format differences between online handouts and Word files, formatting errors are inevitable when exporting handouts as Word files. In addition, due to the incompatibility between Word files and typesetting software, the final edited courseware has many losses and errors in content and style.

[0058] Based on the above research, the present disclosure provides a method, device, electronic device and storage medium for typesetting handouts, which have high typesetting accuracy.

[0059] To facilitate understanding of this embodiment, a method for typesetting a lecture note disclosed in an embodiment of the present disclosure is first introduced in detail. The execution subject of the method for typesetting a lecture note provided in an embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device can be a user equipment (User Equipment, UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the method for typesetting a lecture note can be implemented by a processor calling a computer-readable instruction stored in a memory.

[0060] See also Figure 1 FIG. 1 is a flowchart of a method for typesetting lecture notes provided in an embodiment of the present disclosure, wherein the method includes steps S101 to S104, wherein:

[0061] S101: Obtaining a lecture file in a first document format to be typeset;

[0062] S102: Based on the standard content model, the lecture file is standardized to obtain a standard file; the standard content model is used to uniformly describe the content and style of rich text documents in different document formats;

[0063] S103: Obtaining a target typesetting system file based on the standard file and the target typesetting system configuration information;

[0064] S103: Typesetting the target typesetting system file to generate a typesetting lecture file in a second document format.

[0065] In order to facilitate understanding of the method for typesetting handouts provided by the embodiment of the present disclosure, the application scenario of the method is briefly described below. The above-mentioned method for typesetting handouts can be mainly applied to online education scenarios, which can help teaching and research teachers to typeset handout files into typeset high-printing quality handout files for the convenience of teaching and research teachers. The handout files to be typeset here can be handout files edited using an online handout editing tool, which have a special data structure. The high-printing quality handout files here can refer to rendered PDF files, which have better visualization effects.

[0066] The format of the lecture file to be typeset may be a first document format that describes the content and style of the rich text using the EasySync OT data structure of the collaborative protocol. The readability of the EasySync OT data structure is relatively poor.

[0067] In order to better realize the typesetting of the lecture file, the lecture file with the first document format can be standardized to obtain a standard file, which can not only well describe the conversion relationship between the lecture file and other various files, but also solve the above-mentioned problem of poor readability. In this way, after configuring the standard file using the target typesetting system configuration information, the target typesetting system file can be obtained.

[0068] The target typesetting system file here can be a file with good typesetting performance, for example, it can be a LaTeX file, so that after typesetting the target typesetting system file, a lecture file in the second document format after typesetting can be obtained. For example, in the case where the LaTeX file is used as the target typesetting system file, the lecture file in the second document format after typesetting here can be a PDF file. In specific applications, the final typesetting effect can be achieved through rendering technology, which will not be elaborated here.

[0069] In the disclosed embodiment, standardized processing of lecture files can be implemented based on a standard content model. The standard content model here is used to uniformly describe the content and style of rich text documents in different document formats. That is, it can be used as an intermediate model for conversion of various document formats. This ensures the universality and scalability of the content conversion service and realizes mutual conversion between various document formats.

[0070] The above standard content model can be a standard model extracted from various document formats, and can take into account various document formats. In this way, the target typesetting system file can be obtained conveniently and quickly using the target typesetting system configuration information. It can be seen that for the lecture file with poor readability in the first document format, standardization processing under the constraint of high readability can be performed here, and then the typesetting operation for the target typesetting system file with good typesetting characteristics can be realized. In this way, the lecture file with the second document format obtained greatly reduces the probability of loss and error in typesetting content, making the typesetting accuracy higher.

[0071] The target typesetting system configuration information in the disclosed embodiment may be a configuration command for a target typesetting system file. In a specific application, corresponding configuration commands may be selected based on different target typesetting system files. Considering the excellent characteristics of LaTeX files at the typesetting level, LaTeX files may be used as target typesetting system files.

[0072] For LaTeX files, a preset typesetting engine can be called in the disclosed embodiment to implement typesetting. In specific applications, the XeTeX typesetting engine can be used to compile and render to support OpenType font technology and generate PDF files.

[0073] The XeTeX typesetting engine can be included in the TeX Live software distribution package, and the distribution image in the TeX Live software distribution package can be packaged in the service image. In this way, the LaTeX file can be compiled into a PDF file by directly calling the XeTeX typesetting engine, and rendered on the client to display the PDF file.

[0074] Considering the key role of the generation of standard files in subsequent typesetting, the process of generating standard files can be described below, which specifically includes the following steps:

[0075] Step 1: parsing the lecture file based on a predefined file parsing model to parse out first file data information matching the file parsing model;

[0076] Step 2: Determine the parsed file based on the parsed first file data information and the file parsing model;

[0077] Step 3: converting the parsed file based on a predefined standard content model to obtain second file data information matching the standard content model;

[0078] Step 4: Obtain a standard file based on the obtained second file data information and the standard content model.

[0079] Here, considering that the readability of the lecture file in the first document format is poor, the lecture file can first be parsed using a predefined file parsing model to parse out the first file data information that matches the file parsing model. The analysis here can be an analysis of the collaborative data structure EasySync OT of the lecture file to be typeset.

[0080] The above file parsing model can be used to describe the content and attributes of file paragraphs and each block within a paragraph, and can be understood as a framework model. Taking online education as an example, the first file data information parsed here can be the content of the relevant blocks, including special business metadata such as test questions and subject plug-ins in online handouts, or the attributes of the relevant blocks, including data such as the style of the test questions.

[0081] It should be noted that the specific content of the corresponding file paragraphs may be different for different educational subjects. For example, in mathematics, the file paragraph here may point to a math problem, which may include the title, stem, etc. The title and stem here may correspond to a block respectively, and have their own attributes, for example, the title is in the style of size 4 font, and the stem is in the style of a picture; for another example, in Chinese, the file paragraph here may correspond to a paragraph of an article.

[0082] Here, the first file data system information is input into the file parsing model, and the parsed file can be determined. For the parsed file, the embodiment of the present disclosure can convert the parsed file based on the standard content model. The standard content model here can also be understood as a framework model that describes a universal document format. Similarly, here, the second file data information obtained by converting the parsed file can be input into the standard content model, and the standard file can be determined.

[0083] The method for typesetting handouts provided in the embodiment of the present disclosure can generate a target typesetting system file based on a standard file. In the case where a LaTeX file is used as the target typesetting system file, the LaTeX file can be obtained by following the steps below:

[0084] Step 1: Read each paragraph of the standard file in sequence; each paragraph includes at least one block;

[0085] Step 2: for each block in each paragraph read, perform attribute analysis on the block based on a preset attribute analyzer to determine the attribute of the block;

[0086] Step 3: Based on the preset correspondence between each attribute and each LaTeX command, determine the LaTeX command that matches the attribute of each block;

[0087] Step 4: Get the LaTeX file based on the LaTeX commands that match the attributes of each block.

[0088] In order to better implement batch modification based on attributes, the embodiment of the present disclosure provides a solution for separately configuring the attributes and contents of the blocks with commands.

[0089] Here, we can first implement attribute parsing of each block based on the attribute parser, and then determine the LaTeX command that matches the attributes of the block, and then determine the final LaTeX file through the inclusion relationship between the block and the paragraph, and the arrangement order between the paragraphs. This can be achieved through the following steps:

[0090] Step 1: For each block in each paragraph, bind the LaTeX command matching the attribute of the block and the content of the block to obtain the LaTeX command line corresponding to the block;

[0091] Step 2: For each paragraph, combine the LaTeX command lines corresponding to the blocks belonging to the paragraph to obtain the LaTeX command line corresponding to the paragraph;

[0092] Step 3: Combine the LaTeX command lines corresponding to each paragraph according to the arrangement order of each paragraph to obtain a LaTeX file.

[0093] Considering that in the actual writing process, LaTeX will reference a large number of macro packages and custom macro commands, and often needs to modify the style definitions used to achieve the setting of the style required for typesetting. Therefore, the LaTeX commands here can mainly be pre-defined macro commands. That is, each attribute can point to a macro command. After determining the corresponding macro command, the content of the corresponding block can be bound to the macro command to obtain the LaTeX command line corresponding to the block. In this way, if the style needs to be modified later, it is only necessary to modify the pre-defined macro command, which greatly saves typesetting editing time.

[0094] The typesetting operation in the disclosed embodiment may include a modification operation on a LaTeX file. Here, an editing window may be provided on the client, and when it is determined that an editing instruction for the LaTeX file is received from the client, the LaTeX file is modified based on the editing instruction to obtain a modified LaTeX file, and then the modified LaTeX file is typeset to generate a typeset PDF file.

[0095] The above-mentioned editing instruction may be determined by receiving a style editing instruction of a macro command matching the attributes of any block included in the LaTeX file, that is, the macro command may be modified on the client to select the style to be applied, or it may be determined by receiving a content editing instruction of any block included in the LaTeX file, that is, the block content may be modified on the client to determine the modified content.

[0096] No matter which of the above editing instructions is used, it can be initiated by the online LaTeX editor set up on the client, which is mainly to enable typesetters to perform editing operations better.

[0097] In order to understand the interaction process between the above server and client, we can combine Figure 2 Further explanation.

[0098] like Figure 2 As shown, an editor interface is presented on the client. On the current editor interface, the user can use the LaTeX editor to initiate editing instructions, so that the server can perform relevant modification operations directed to specific LaTeX files based on typesetting project management. The modification here can be a modification of the content of the handout or a modification of the handout layout.

[0099] Regardless of the above modification method, in the embodiment of the present disclosure, LaTeX file compilation can be performed on the server side, and the compiled PDF file can be rendered on the editor interface of the client side.

[0100] The method for typesetting lecture notes provided by the embodiment of the present disclosure can also use standard files to achieve conversion between different files to meet the user's file conversion needs. Here, when it is determined that a conversion instruction is received from a target typesetting system file to other target typesetting system files, the standard file corresponding to the target typesetting system file is obtained, and based on the standard file and other typesetting system configuration information, other typesetting system files are obtained.

[0101] The other typesetting system files here may be HTML files, Word files, or other system files, and the embodiments of the present disclosure do not impose specific limitations on this.

[0102] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0103] Based on the same inventive concept, an apparatus for lecture note typeset corresponding to the method for lecture note typeset is also provided in the embodiments of the present disclosure. Since the principle of solving the problem by the apparatus in the embodiments of the present disclosure is similar to the method for lecture note typeset mentioned above in the embodiments of the present disclosure, the implementation of the apparatus can refer to the implementation of the method, and the repeated parts will not be repeated.

[0109] By using the above-mentioned lecture note typeset device, the lecture note files to be typeset can first be standardized based on the standard content model to obtain standard files. Since the standard content model here is used to uniformly describe the content and style of rich text documents under different document formats, the standard files generated based on the above-mentioned standard content model can well take into account the lecture note files and the typesetting system files, ensuring the compatibility between the target typesetting system files generated by the subsequent configuration of the standard files based on the target typesetting system configuration information and the typesetting system, thereby reducing the probability of loss and errors in the typeset content and making the typesetting accuracy higher.

[0112] Determine a parsed file according to the parsed first file data information and the file parsing model;

[0122] For each paragraph, combine the LaTeX command lines corresponding to the blocks belonging to the paragraph to obtain the LaTeX command line corresponding to the paragraph;

[0123] The LaTeX command lines corresponding to the paragraphs are combined according to the arrangement order of the paragraphs to obtain a LaTeX file.

[0124] In a possible implementation, the lecture file in the second document format includes a PDF file, and the typesetting module 304 is used to typeset the target typesetting system file according to the following steps to generate a typeset lecture file in the second document format:

[0125] When it is determined that an editing instruction for the LaTeX file is received from the client, the LaTeX file is modified based on the editing instruction to obtain a modified LaTeX file;
