[0042] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] According to a first aspect of the present invention, a document translation method is provided, optionally, as follows: Figure 1 As shown, the above method includes:

[0045] S102, during the process of displaying the current page, if a translation instruction is obtained to translate the first document under the target link, the document to be translated in a predetermined format corresponding to the first document is obtained;

[0046] S104, Translate the document to be translated to obtain the translated document;

[0047] S106, Display the translated document in a pre-defined mode on the target page.

[0048] Optionally, the above document translation method can be used during the document translation process. When the current page is displayed, if a translation instruction to translate the first document under the target link is triggered, a document to be translated in a predefined format corresponding to the first document can be obtained. The first document can have multiple formats, and the document to be translated is a first document in one of these formats. After translating the document to be translated to obtain the translated document, the translated document can be displayed on the target page.

[0049] The current page mentioned above can be the page used to display or download the first document, or it can be the front-end page of the translation system. The target page mentioned above can be a front-end page of the translation system that is different from the current page. For example, one can jump from the current page to the target page, or create a new tab and display the target page in the new tab.

[0050] The aforementioned pre-defined format can be one of the formats of the first document. The purpose of obtaining the first document in the pre-defined format is to improve the efficiency of the translation process, rather than to complicate the translation process by first converting the first document in the pre-defined format to a different format before translating it.

[0051] In the above method, when translating the first document, only the translation command needs to be triggered, and the system can automatically translate the first document in the predetermined format without copying the entire first document. This achieves the goal of reducing the complexity of the translation operation and thus solves the technical problem of high translation operation complexity.

[0052] As an optional example, the current page is the download page where the first document is located. The first document in a first format different from the predetermined format can be downloaded through the current page. During the display of the current page, the above method also includes: displaying a translation control; determining that a translation instruction has been obtained when the translation control is triggered; and obtaining the predetermined format document corresponding to the first document displayed on the current page as the document to be translated.

[0053] In this embodiment, there are several ways to obtain translation instructions. As a first method, it can be triggered by a translation control.

[0054] As an optional example, the translation control includes: displaying the translation control when navigating from a first page to the current page, wherein the first page is a page that displays a document link to a first document, the first page displays multiple document links, including a document link to the first document, and navigating from the first page to the current page when a document link to the first document is triggered.

[0055] Optionally, in this embodiment, the translation control can be displayed in real time or triggered under certain conditions. For example, the triggering condition can be a jump from the first page to the current page. The first page can be any page; as an example, the first page is the page that displays document links. Each document link on the first page can be used to jump to a document display or download page.

[0056] As an optional example, obtaining a pre-formatted document corresponding to the first document displayed on the current page as the document to be translated includes: sending an acquisition request to a target server, wherein the acquisition request includes the document encoding of the first document in the webpage link of the current page, the acquisition request is used to download the pre-formatted document to be translated according to the document encoding, and the target server is a third-party server providing the document to be translated; receiving the pre-formatted document to be translated returned by the target server; and translating the document in a pre-defined mode on the target page includes: creating a new tab; and using the newly created tab as the target page.

[0057] Optionally, in this embodiment, after receiving the translation instruction, a document to be translated needs to be obtained. The document to be translated is in a predetermined format. The predetermined format can be LaTeX format. In this embodiment, a first document in LaTeX format is obtained as the document to be translated, and then translation is performed.

[0058] When retrieving a first document in LaTeX format, a retrieval request can be sent to the target server, which then provides the LaTeX document. The retrieval request can include the document encoding, allowing the target server to download the first LaTeX document as the document to be translated.

[0059] Once you have both the document to be translated and the translated document, you can display the translated document using a pre-defined mode. This pre-defined mode opens a new tab in your browser, redirecting you from the current page to the target page displayed in that new tab. The target page displays both the original and translated documents.

[0060] As an optional example, the current page is the front-end page of the translation system. During the display of the current page, the above method further includes: determining that a translation instruction has been obtained when the target link is filled into the translation input box of the current page, or when the target link is filled into the translation input box of the current page and the translation button is triggered; the page corresponding to the target link is the download page of the first document, through which a first document in a first format different from the predetermined format can be downloaded; and obtaining the document in the predetermined format corresponding to the first document as the document to be translated based on the target link.

[0061] As another way to obtain translation instructions, the download page of a first document in a different format than the predetermined format can be used as the target link. The current page is the front-end page of the translation system. The target link is entered into the input box on the front-end page to obtain the translation instructions.

[0062] For example, such as Figure 2 As shown, Figure 2 For the front-end page of the translation system, the target link can be entered or copied into the input box under the first or second language, thereby translating the first document into a translated document in another language.

[0063] As an optional example, obtaining a document in a predetermined format corresponding to the first document as the document to be translated, based on the target link, includes: sending an acquisition request to the target server, wherein the acquisition request includes the document encoding of the first document of the target link, the acquisition request being used to download the document to be translated in a predetermined format according to the document encoding, and the target server being a third-party server providing the document to be translated; and receiving the document to be translated in a predetermined format returned by the target server.

[0064] Optionally, in this embodiment, after receiving the translation instruction, a document to be translated needs to be obtained. The document to be translated is in a predetermined format. The predetermined format can be LaTeX format. In this embodiment, a first document in LaTeX format is obtained as the document to be translated, and then translation is performed.

[0065] When retrieving a first document in LaTeX format, a retrieval request can be sent to the target server, which then provides the LaTeX first document. The retrieval request can include a document code identifying the specific first document, allowing the target server to download the LaTeX first document as the document to be translated.

[0066] As an optional example, displaying the translated document in a pre-defined mode on the target page includes: navigating from the current page to the target page; and displaying the translated document in a pre-defined mode on the target page.

[0067] In this embodiment, when the translated document is displayed, the user can jump from the current page to the target page. This jump does not trigger a new tab; instead, it jumps within the current tab.

[0068] As an optional example, displaying the translated document in a predetermined mode on the target page includes: displaying the translated document on the target page according to the layout rules of a first document in a first format that is different from the predetermined format.

[0069] Optionally, in this embodiment, the first format can be a portable document format (PDF), the document to be translated is in LaTeX format, and the translated document is displayed in PDF format.

[0070] When displayed, both have the same layout but different languages. For example, as Figure 3 As shown, the translated document has the same layout as the original PDF document.

[0071] In other words, in this embodiment, the LaTeX document is first translated to obtain a translated document. Then, when displaying the translated document, the text content of the translated document can be displayed directly, or the translated document can be displayed in the PDF format of the first document (the source language document).

[0072] In this embodiment, for a document in LaTeX format that has already been translated, if the same user or different users request to translate the document, the initial translation result can be retrieved directly without the system repeating the translation. If the initial translation result is too far removed from the current time or the data is lost, the system can translate it again.

[0073] As an optional example, displaying the translated document on the target page according to the layout rules of the first document in a first format different from the predetermined format includes: obtaining the first document in a first format different from the predetermined format according to the target link; displaying the first document and the translated document side-by-side on the target page; and displaying both the first document and the translated document according to the layout rules of the first document in the first format.

[0074] In this embodiment, when displaying the translated document, the first document (source language document) in PDF format can be displayed, and when displaying the translated document, the translated document is displayed according to the layout of the first document in PDF format, and the display layouts of the two are the same.

[0075] As an optional example, the first document and the translated document are displayed side-by-side on the target page; both the first document and the translated document are displayed according to the first format layout rules of the first document, and also include: when the first content in the first document is selected, the corresponding content in the translated document is highlighted; when the second content in the translated document is selected, the corresponding content in the first document is highlighted.

[0076] In this embodiment, when the first document and the translated document are displayed side-by-side, the first document displays the source language text, and the translated document displays the translated text. The two documents have the same display layout and are used for comparison. If content in one document is selected, the corresponding content at the corresponding position is highlighted in the other document.

[0077] For example, such as Figure 4 As shown, Figure 4 In the first document or the translated document, if any segment is selected or marked, it will be selected or marked in the other document simultaneously and highlighted.

[0078] As an optional example, translating a document to be translated to obtain a translated document includes: the document to be translated is a LaTeX format document; each fragment of the original string in the document to be translated is converted into a string representation, generating an array of original strings and an original element type identifier; the original strings are converted into a first string according to whether the string representations in the original strings are plain text, wherein the first string includes a special identifier; the special identifiers in the first string are filtered out to obtain a second string; the second string is translated to obtain a translated third string; the target string of the translated document is determined based on the first string, the second string, and the third string.

[0079] In this embodiment, the original string can be divided into paragraphs, which contain one or more segments. Each segment can be converted into a string representation, and then its conversion into the first string is determined by whether it is plain text. This can be understood as follows: the first string is the string obtained by adding special identifiers to the plain text segments of the original string; the second string is the string obtained by filtering out the special identifiers; and the third string is the string obtained by translating the second string. Therefore, the first string is the formatted, untranslated string; the second string is the unformatted string to be translated; and the third string is the unformatted translated string. These three are used to determine the formatted, translated target string.

[0080] As an optional example, converting the original string to a first string based on whether the string representation in the original string is plain text includes: preserving the string representation if the string representation is plain text; and adding a special identifier to the string representation if the string representation is not plain text.

[0081] Optionally, the above conversion of the original string to the first string can be achieved by preserving the string representation if the original string's string representation is plain text, and adding special identifiers to the string representation if the string representation is not plain text. Therefore, the first string is the original string in which plain text has been modified with special identifiers.

[0082] As an optional example, determining the target string of the translated document based on the first string, the second string, and the third string includes: performing word segmentation on the second string and the third string; establishing relationships between the word segments; determining the position of the text fragment in the second string within the first string; and replacing the string representation in the first string with the string representation in the third string according to the relationships and positions to obtain the target string.

[0083] As an optional example, translating the second string to obtain the translated third string includes: translating the second string according to the required translation method to obtain the third string.

[0084] In this embodiment, different strings can be configured with different translation methods. Therefore, when translating the second string, the second string is translated according to the translation method required for the second string to obtain the third string.

[0085] In this embodiment, the document to be translated can be a LaTeX document, also known as the original document, and the translated document can be called the target document. LaTeX is a TeX-based typesetting system that uses a combination of text and commands to control styles and layout. For a LaTeX document, the original string to be translated is first determined, then translated to obtain the target string, and finally the target string is added back to the original document to obtain the translated target document. The original document mentioned above can be a LaTeX source project package. A LaTeX project package can include multiple files.

[0086] The following method can be used to determine the original string: Filter candidate original files from all files in the original document according to their file extensions; generate a file tree of candidate original files; use the file containing the predetermined characters in the candidate original files as the entry file; starting from the entry file, filter the first file from the candidate original files according to the file reference relationship contained in the command type node in the file, where the type of the node is determined according to the file tree; determine the paragraph in the first file as the original string.

[0087] The above-described method of filtering candidate original files from all files in the original document by file extension can be used to select files with one or more specific file extensions from all files in the original document. For example, filtering files with the ".tex" extension can select candidate original files from all files in the original document.

[0088] For candidate original files, an entry file can be selected. The selection rule can be to check whether the candidate original file contains a predetermined character. There can be at least two rules. The first is to traverse each candidate original file, and when a specific character is encountered for the first time, select the candidate original file containing that specific character as the entry file. The second is to traverse each candidate original file, and when the specific character is encountered, select one candidate original file containing that specific character as the entry file according to a certain rule.

[0089] Before or after the entry file is determined, a file tree of candidate original files can be generated. The file tree can be understood as a node tree with a root node and leaf nodes. After the file tree is generated, different nodes within the file tree can have different types.

[0090] The entry file can be used as a starting point, and then the file reference relationships contained in the command type nodes can be queried according to the node tree. The file reference relationship indicates which files the entry file references, and whether the files referenced by the entry file in turn reference other files. It should be noted that the file reference relationship must be queried within the command type nodes. Based on the above reference relationships, multiple first files can be identified from the candidate original files.

[0091] After identifying the first file, the paragraphs in the first file can be identified as the original strings, i.e., the content that needs to be translated.

[0092] The file tree for generating candidate original files mentioned above can be achieved as follows: create a root node for the candidate original files and use the root node as the current node; traverse the string variables of the candidate original files; for each command start character encountered during traversal, generate a command child node for the current node and use the command child node as the new current node; for each command end character encountered during traversal, use the parent node of the current node as the new current node; for each plain string encountered during traversal, generate a text child node for the current node.

[0093] For example, such as Figure 5 and Figure 6 As shown, Figure 5 The file tree generated for the following TeX file string variables: "command1 start character plain string1 command1 end character command2 start character plain string2 command2 end character".

[0094] Figure 6 The file tree generated for the following TeX file string variables: command1 start character plain string1 command2 start character plain string2 command2 end character command1 end character.

[0095] Optionally, determining the paragraphs in the first file as raw strings can be done by: generating an intermediate representation with a hierarchical structure from the first file's file tree, wherein the hierarchical structure includes paragraph layers; and determining the strings corresponding to the paragraphs as raw strings.

[0096] In this embodiment, the hierarchical structure can be a nested structure, such as "{ [()]}", which can be considered a three-level hierarchical structure of curly braces, square brackets, and parentheses. The intermediate expression mentioned above can be a JSON structure. That is, the file tree of the first file (the candidate original file includes one or more first files) is used to generate a multi-level intermediate expression in JSON format according to different levels. Among them, the hierarchical structure includes a "paragraph" hierarchical structure. The strings in the paragraph structure are determined as the original strings to be translated.

[0097] Optionally, in this embodiment, generating an intermediate representation with a hierarchical structure from the first file can be achieved by: using the file tree of the first file as the file layer of the intermediate representation; using the command node related to each document structure in the file tree of the first file as the structural block layer of the intermediate representation; using the command node related to each document element in the file tree of the first file as the paragraph layer of the intermediate representation; using each leaf node in the file tree of the first file as the fragment layer of the intermediate representation; and constructing different translation strategies for different structural block layers.

[0098] Optionally, the document structure and document elements described above may include specific tags. These tags can identify which nodes are document structure elements and which are document elements. Through a hierarchical structure, the first file is divided into different levels, each representing different content, further facilitating the identification of the original string. Different translation strategies can be configured for different structural block levels to achieve better translation results.

[0099] By following the steps described above, the content to be translated can be determined from a document in a specific format.

[0100] For example, taking LaTeX format documents as an example, for a LaTeX source project package, each file in the LaTeX source project package is traversed according to a breadth-first strategy. For files with the suffix ".tex", their contents are read into a string variable, and these TeX file string variables are stored in an array to form a TeX file set. Then, the TeX file set is traversed, and it is determined whether each TeX file string variable contains the substring "\documentclass". "\documentclass" is the predefined string mentioned above. If it contains it, its index in the array is set as the index of the entry TeX file, and the traversal ends early.

[0101] Next, construct the LaTeX document tree. Create an empty queue of TeX collections to be constructed. First, add the TeX file corresponding to the entry TeX file index to this collection. Then, retrieve the TeX files from this collection one by one for processing until the collection is empty, at which point the processing ends.

[0102] The processing steps for each TeX file are as follows: parse the TeX file string variable into a TeX tree, then traverse the command nodes on the TeX tree, collect all the parameters of the "\input" command, which correspond to other TeX files that need to be imported, and add these files to the queue of the TeX collection to be built in sequence.

[0103] The steps for parsing the strings corresponding to a TeX file into a TeX tree are as follows: First, create a root node for the TeX tree, and set the current node pointer to this root node. Then, traverse the string variables in the TeX file. When encountering the start character of a command in LaTeX syntax, create a new command node and add it to the subtree set of the node pointed to by the current node pointer. Use the original pointer to point to the node pointed to by the current node pointer, and then set the current node pointer to the newly created command node. When encountering the end character of a command corresponding to the current node in LaTeX syntax, reset the current node pointer to the original pointer. When encountering a plain string, create a new plain text node and add it to the subtree set of the node pointed to by the current node pointer.

[0104] An array is used to store all the TeX trees obtained during the processing, which is the LaTeX document tree corresponding to the LaTeX document. The LaTeX document tree contains multiple TeX trees, and each TeX tree corresponds to a first document.

[0105] Finally, a hierarchical intermediate representation is generated. The entire document uses a JSON structure as the hierarchical intermediate representation and is divided into four levels: "File," "Block," "Paragraph," and "Fragment," based on the characteristics of the LaTeX document structure. "File" corresponds to each TeX file, ensuring a one-to-one correspondence between JSON objects and the TeX tree. "Block" corresponds to command nodes related to the document structure in the TeX tree (e.g., title, author, abstract, bibliography), ensuring different translation schemes can be used for different document structures. "Paragraph" corresponds to a collection of plain text nodes separated by command nodes related to document elements (e.g., figure, table, list) or commands with clear paragraph division meanings (e.g., \par, \\\). This level is the smallest unit of translation to maintain semantic fluency. "Fragment" corresponds to the leaf nodes in the TeX tree, including plain text nodes, text style command nodes (e.g., \textbf, \emph), and non-translated element command nodes (e.g., formulas, quotations). This level is the smallest unit in LaTeX syntax to maintain LaTeX syntax styles. Based on the four levels mentioned above, a JSON representation with four nested levels can be generated by traversing each node in the LaTeX document tree using a depth-first strategy. Each JSON object includes an array of JSON objects at the next level of its nesting, a type field (here, the corresponding command name is used as the node type), and an index pointing to a specific command node or a set of plain text nodes.

[0106] Finally, the string corresponding to the paragraph is used as the original string to determine the original string to be translated.

[0107] The steps for translating the original string to obtain the target string can be as follows: each segment of the original string can be converted into a string representation, generating an array of original strings and an identifier for the original element type; the original string can be converted into a first string according to whether the string representation in the original string is plain text, where the first string includes a special identifier; the special identifier in the first string can be filtered out to obtain a second string; the second string can be translated to obtain a translated third string; and the target string can be determined based on the first string, the second string, and the third string.

[0108] Since the original string is organized into paragraphs, it contains one or more segments. Each segment can be converted into a string representation, and then its conversion to the first string is determined by whether it is plain text. This can be understood as follows: the first string is the plain text portion of the original string with special identifiers added; the second string is the string after filtering out the special identifiers; and the third string is the translated version of the second string. Therefore, the first string is the formatted, untranslated string; the second string is the unformatted string to be translated; and the third string is the unformatted translated string. These three strings are used to determine the formatted, translated target string.

[0109] When determining the target string, the second and third strings can be segmented; relationships can be established between the segments; the position of the text fragment in the second string within the first string can be determined; and according to the relationships and positions, the string representation in the third string can be replaced with the string representation in the first string to obtain the target string.

[0110] Optionally, the above conversion of the original string to the first string can be achieved by preserving the string representation if the original string's string representation is plain text, and adding special identifiers to the string representation if the string representation is not plain text. Therefore, the first string is the original string in which plain text has been modified with special identifiers.

[0111] In this embodiment, since each structure block can be configured with different translation methods, paragraphs within different structure blocks can have different translation methods. The second string is translated according to the translation method required by the structure block containing the second string to obtain the third string.

[0112] For example, continuing with the LaTeX document format, in this embodiment, by traversing the hierarchical intermediate expressions, a translation strategy is executed on a "paragraph" basis for the original string to be translated. Different global translation strategies can be constructed for different "structural blocks." For instance, for the `author` structural block, a separate translation engine can be used to translate the names of the person and organization, or it can be left untranslated; for the `title` structural block, all titles in the document can be aggregated and translated together, utilizing more context to avoid mistranslation; for the `bibliography` structural block, the paper titles can be extracted separately for translation or left untranslated.

[0113] When translating a paragraph, the first step is to construct a formatted string to be translated (the first string). Each segment within the paragraph is iterated through and converted into a string representation, generating an array of original text strings corresponding to the paragraph. The conversion rule is as follows: determine if the text is plain text; if so, use the corresponding plain text content as the string representation; otherwise, use a predefined, numbered special token as the string representation. Next, each element in the string array corresponding to the paragraph is marked as formatted. This is done by iterating through the array and checking if the next element's string is a numbered special token; if not, mark the current element as formatted. Finally, the original text string array is concatenated in order. Unformatted strings are concatenated directly, while formatted strings are concatenated by adding formatted token pairs to both sides before concatenation, generating the formatted string to be translated. Then, the unformatted translation result string is obtained. The formatted string to be translated is filtered to remove the formatted token pairs, generating an unformatted string to be translated (the second string). This unformatted string is then input into a pre-trained translation engine to obtain the unformatted translated string (the third string). The pre-trained translation engine uses the same training data pairs to ensure that the special tokens with serial numbers are preserved in the translated text. Finally, the formatted translated string (the target string) is obtained. First, both the unformatted string to be translated and the unformatted translated string are segmented into words. Using the formatted string as a unit, the start and end positions of each formatted token pair within the unformatted word sequence are determined. A nested tree structure is constructed based on the nesting relationships between the formatted token pairs. Then, the Fast-Align algorithm is used to obtain the word alignment relationship between the unformatted word sequence to be translated and the unformatted translated word sequence. Finally, the nested tree structure is traversed using a depth-first strategy. The start and end positions of each node in the unformatted sequence of words to be translated are mapped to the unformatted sequence of translated words. These are then inserted into the unformatted translated string to obtain the formatted translation result (target string).

[0114] After translating the target string, it can be used to fill in the original document, replacing the original string, thus obtaining the translated target document. The filling process involves two steps. The first step is to map each substring in the target string array to each object in the original string array based on the correspondence between the original element type identifier and the target element type identifier, adding an object field and assigning a value to each object in the original string array. The second step is to fill in the translated target string back into the original document to obtain the target document.

[0115] The first step can be accomplished using pointers. Use the first pointer to point to the first object in the original string array and the second pointer to point to the first substring in the target string array. Taking the object pointed to by the first pointer as the current object and the substring pointed to by the second pointer as the current substring, perform the following operations: If the element type corresponding to both the current object and the current substring is plain text, add a translation field to the current object, assign the value of the current substring to the translation field, and move the first pointer to the next object and the second pointer to the next substring. If the element type corresponding to both the current object and the current substring is not plain text, and the index of the special identifier of the current object and the current substring is different, add a replacement field to the current object, assign the value of the index of the special identifier of the current substring to the replacement field, move the first pointer to the next object, and the second pointer to the next substring. If the element type corresponding to both the current object and the current substring is not plain text, and the index of the special identifier of the current object and the current substring is the same, move the first pointer to the next object. The process begins by setting the second pointer to the next substring. If the current object is plain text and the element type corresponding to the current substring is not plain text, a translation field is added to the current object, its value is set to null, and the first pointer is set to the next object. If the element type corresponding to the current object is not plain text and the element type corresponding to the current substring is plain text, a pre-translation field is added to the current object, the value of the current substring is assigned to the pre-translation field, and the second pointer is set to the next substring. If the first pointer points to the end of the original substring, a post-translation field is added to the current object, the concatenation result of all substrings between the current substring and the end of the target substring is assigned to the post-translation field, and the second pointer is set to the end of the target substring. If the second pointer points to the end of the target substring, a translation field is added to all objects between the current object and the end of the original substring, its value is set to null, and the first pointer is set to the end of the original substring.

[0116] The second step, if the object in the original string array contains a translation field, is to modify the text of the first plain text node under the command node or the first node in the plain text node set of the original document pointed to by the object to the value of the translation field, and set the values ​​of the remaining plain text nodes to empty. If the object in the original string array contains a previous translation field, the first node under the command node or the first node in the plain text node set of the original document pointed to by the object is taken as the current node. A new plain text node is inserted at the index of the current node in the child node set of the parent node of the current node, and the value of the new plain text node is set to the previous translation field. The value of the translation field; if the object in the original string array contains a post-translation field, take the last node under the command node or the last node in the plain text node set of the original document pointed to by the object as the current node, insert a new plain text node at the index after the current node in the child node set of the current node's parent node, and set the value of the new plain text node to the value of the post-translation field; if the object in the original string array contains a replacement field, determine the node to be replaced from all nodes under the nearest common parent node of the node corresponding to the object and the node corresponding to the replacement field's index, and perform the replacement operation on the position of the node to be replaced.

[0117] Continuing with the LaTeX document as an example, we append backfill information to the intermediate expressions. By matching special tokens with serial numbers and format tokens, we split the formatted translation results into arrays of translated strings. We define source and translated string pointers, pointing to the source string array and the translated string array respectively, and process them sequentially until both pointers point to the end of their respective arrays. The processing rules are as follows: If both pointers point to plain text, add a "translation" field to the JSON object corresponding to the original pointer's position, with the value being the string corresponding to the translated pointer's position, and then move both pointers one position to the right. If both pointers point to non-plain text, for cases where the two special token numbers are inconsistent, add a "replace" field to the JSON object corresponding to the original pointer's position, with the value being the sequence number of the special token corresponding to the translated pointer's position, and then move both pointers one position to the right. For cases where the two special token numbers are consistent, only move both pointers one position to the right. If the original pointer points to plain text and the translated pointer points to non-plain text, add a "translation" field to the JSON object corresponding to the original pointer's position, with the value being an empty string, and then move the original pointer one position to the right. If the original pointer points to non-plain text and the translated pointer points to... For plain text, add a "translation-before" field to the JSON object corresponding to the position pointed to by the original pointer. The value of this field is the string at the position pointed to by the translation pointer. Then, move the translation pointer one position to the right. If the original pointer points to the end of the original string array, add a "translation-after" field to the JSON object corresponding to the last position of the original string array. The value of this field is the concatenation of all strings between the position pointed to by the translation pointer and the end of the translation string array. Then, move the translation pointer to the end of the translation string array. If the translation pointer points to the end of the translation string array, add a "translation" field to all corresponding JSON objects in the original string array between the position pointed to by the original pointer and the end of the original string array. The value of this field is an empty string. Then, move the original pointer to the end of the original string array.

[0118] The LaTeX document tree is adjusted based on the backfilled information. First, the intermediate JSON objects are traversed using a depth-first strategy. If the JSON object contains a "translation" field, the command node or plain text node set pointed to by the JSON object is retrieved. The text of the first plain text node under the corresponding command node or the first node in the plain text node set is modified to the value corresponding to the "translation" field, and the text of the remaining plain text nodes is modified to an empty string. If the JSON object contains a "translation-before" field, the first node under the specific command node pointed to by the JSON object or the first node in the plain text node set is taken as the current node. In the subtree set of the current node's parent node, a new node is inserted at the current node's index. A new plain text node is created, with its text being the value corresponding to the "translation-before" field. If the JSON object contains a "translation-after" field, the last node under the specific command node pointed to by the JSON object, or the last node in the plain text node set, is taken as the current node. In the subtree set of the current node's parent node, a new plain text node is inserted at index + 1 of the current node, with its text being the value corresponding to the "translation-after" field. If the JSON object contains a "replace" field, the node pair consisting of the node corresponding to the current JSON object and the node with the index corresponding to the "replace" field is added to the set to be reordered. Then, the set to be reordered is sorted, ordered from largest to smallest by the index of the first node in each node pair. Finally, the node pairs in the set to be reordered are traversed sequentially, and it is determined whether there is a fork in the path from the two nodes of the node pair to their nearest common ancestor node. If a fork exists (e.g., ...), the node pairs are reordered. Figure 7 As shown), then node splitting is performed (e.g. Figure 8 As shown), ensure that there are no branches on the path to the nearest common ancestor node, and then obtain the last node on the path (i.e., Figure 8 The nodes to be replaced (i.e., the nodes one level below the common ancestor node) are taken as the two nodes to be replaced, such as... Figure 9 The node replacement operation is shown.
