[0033] Figure 1 The system 100 can be configured and operated in various ways to enable the application of the various methods and apparatus described in this disclosure.

[0034] According to one aspect of this disclosure, a method for processing presentation data is provided. For example... Figure 2 As shown, the method includes: step S201, acquiring presentation data based on a preset structured format, the presentation data including structured description information of multiple presentation elements; step S202, converting the presentation data into a page description format supported by the web page editing environment to obtain initial page description data; step S203, drawing multiple presentation elements in the web page editing environment based on the initial page description data; step S204, in response to detecting a target operation on multiple presentation elements, acquiring target page description data of the web page editing environment after the target operation; step S205, comparing the target page description data and the initial page description data to determine the editing intent; step S206, determining a change instruction for the presentation data that conforms to the preset structured format based on the editing intent; and step S207, updating the presentation data using the change instruction.

[0035] Thus, by converting the preset structured format of the presentation data into initial page description data adapted to the web page editing environment, and comparing and analyzing the initial page description data with the target page description data generated after user editing, the non-standardized and visual presentation-based modifications (i.e., changes caused by target operations) generated by the user in the front end are accurately mapped to editing intentions and change instructions conforming to the preset structured format of the back end, improving the accuracy and standardization of the presentation data updating process, and ensuring that the updated presentation data accurately reflects the editing intentions corresponding to the target operations.

[0036] In some embodiments, the preset structured format refers to a data specification independent of a specific rendering environment, used to describe the logical structure and semantic attributes of the presentation. The format can be a custom data model (such as BDJSON) based on JSON (JavaScript Object Notation) or XML (Extensible Markup Language). The format focuses on storing semantic information of the data, rather than the final visual presentation of the data (such as specific pixel rendering instructions).

[0037] The plurality of presentation elements refers to the basic logical units that constitute the presentation page, such as text boxes, pictures, shapes, tables, video components, etc. Accordingly, the structured description information can refer to a set of fields defined in the preset structured format for describing the attributes of the above elements. In an exemplary embodiment, the structured description information can include the unique identifier (ID) of the element, the type (Type), the geometric position parameters (such as the center point coordinates, the width and height), the hierarchical relationship (Z-index), the content data (such as the text string, the picture URL), and the semantic style (such as the font size, the color), etc.

[0038] It should be noted that the presentation data can be directly generated by a generative artificial intelligence model based on user instructions, or can be intermediate state data obtained by parsing and converting an existing presentation file (such as a PowerPoint file, a Keynote file, a PDF file, etc.).

[0039] In some embodiments, the web page editing environment refers to a visual interactive environment built based on a web technology stack (such as HTML, CSS, JavaScript) and running in a browser or a web container. The page description format refers to a standard markup language or object model that can be recognized and rendered by the environment, which can include HTML (HyperText Markup Language) strings, DOM (Document Object Model) tree structures, or Canvas drawing objects, etc.

[0040] The initial page description data can refer to the data generated by a rendering engine or a converter based on the presentation data, in a format of the page description as described above. The conversion process usually involves mapping abstract semantic attributes stored in the backend (e.g. the position information "x": 50 of a presentation element) to concrete rendering attributes in the frontend environment (e.g. style="left: 50px; position: absolute;"), so as to facilitate correct display in the web page.

[0041] In some embodiments, rendering (also referred to as drawing) refers to the process in which a browser or a rendering engine parses the initial page description data, calculates the layout and rendering, and finally presents the corresponding graphical user interface in the visual area of the screen. In this process, multiple presentation elements are instantiated as interactive visual elements (e.g. HTML DOM nodes), so that the user can interact with these elements through input devices such as mouse, touchpad or keyboard, or the agent can interact in a specific way.

[0042] In some embodiments, the target operation can be any visual editing action performed on one or more presentation elements in the web page editing environment. The target operation includes but is not limited to: dragging an element to change its position, dragging a control point to adjust its size, clicking and modifying the text content, modifying the font color or background style through the toolbar, deleting an element or copying and pasting a new element, etc.

[0043] In some embodiments, the target page description data can refer to the page description state of the web page editing environment at the current time after the user performs the target operation. The user's editing operation (such as dragging) is usually directly processed by the web page editing environment (such as the browser engine) and updates the underlying DOM structure or style attributes in real time. In an exemplary embodiment, the dragging operation causes the inline style attribute of the DOM node to change. The target page description data usually contains non-normalized changes relative to the initial page description data, such as automatically generated inline styles, temporary class names or redundant tags by the editor. Such non-normalized changes cannot be directly used to update the presentation data.

[0044] In some embodiments, in step S205, comparing the target page description data and the initial page description data can be achieved by code difference analysis. In this way, it can be identified which changes are made to the presentation elements by the target operation. In an exemplary embodiment, the comparison process can be achieved by comparing the structural differences of the DOM tree, the differences of the attribute values or the differences of the text content.

[0045] In some embodiments, the edit intention can be a semantic abstraction of the above-mentioned difference, i.e., a high-level operation semantics that can be understood by the backend. In an example embodiment, if the comparison finds that the left and top style attributes of a certain element have changed, the determined edit intention can be a "position moving intention"; if it is found that the appearance style of a node has changed, the edit intention can be an "appearance style override intention".

[0046] In some embodiments, the edit intention can be determined in a plurality of pre-defined intention categories. The plurality of pre-defined intention categories can include, but are not limited to, a position moving intention, an appearance style override intention, a content revision intention, an element adding intention, and an element deleting intention.

[0047] In some embodiments, the edit intention can not only represent the type of logical modification that the editor wants to make to the presentation data, but can also include specific modification content. In an example embodiment, the edit intention can also include how many pixels a certain element is specifically moved, the text content of a text box after modification, and the like.

[0048] In some embodiments, the change instruction refers to a set of instructions in a pre-set structured format specification that conforms to the backend, for indicating how to modify the structured presentation data. The process of determining the change instruction is essentially a reverse mapping process. The system converts the non-normalized change data of the front end (such as the change of pixel value) into the required field change of the backend structured data according to the determined edit intention. For example, for a "position moving intention", the system can generate an instruction indicating to update the x field and y field of the corresponding element in the database to specific numerical values; for a "style override intention", the system can generate an instruction indicating to add a style record in the corresponding field of the element.

[0049] In some embodiments, in step S207, the change instruction can be executed to modify the stored presentation data. By executing the update, the structured description information of the backend is synchronized to the latest state, thereby maintaining semantic consistency with the user editing result of the front end.

[0050] In short, by the above-mentioned manner, the front-end visual modification can be accurately mapped to the back-end normalized change instruction, realizing lossless synchronization between the front-end interactive editing view and the back-end presentation data, and ensuring the accuracy and normalization of the presentation data update.

[0051] According to some embodiments, the initial page description data can include the inline style of each of the plurality of presentation elements. For example, the initial page description data can include the inline style of each of the plurality of presentation elements. Figure 3As shown, the comparing the target page description data and the initial page description data to determine the editing intention in step S205 can include: determining, among the plurality of presentation elements, a target presentation element whose corresponding inline style is changed before and after the target operation in step S301; and determining the editing intention based on the change of the inline style of the target presentation element in step S302.

[0052] In this way, by using the change of the inline style as the comparison basis, the underlying visual modification result in the web page editing environment can be directly captured, so that the specific object and type targeted by the target operation can be accurately identified, and the recognition accuracy of the editing intention is improved.

[0053] In some embodiments, the inline style refers to a style declaration directly embedded inside an element tag in the page description format data, such as the content in the style attribute inside an HTML tag. After the presentation element is dragged, scaled, or subjected to other operations, the inline style corresponding to the presentation element will automatically change in the web page editing environment, such as changes in position coordinates or size values.

[0054] In some embodiments, in step S301, the correspondence between the elements in the initial page description data and the target page description data can be first established by means of element ID or the like. Subsequently, these elements can be traversed, the string value or object representation of the style attribute of each element can be extracted one by one, and the initial style attribute value and the target style attribute value of the same element can be compared. If they are inconsistent, the element is determined to be the target presentation element, i.e., the object of the target operation. In an exemplary embodiment, the change of the inline style can include differences in the string or different CSS attribute key-value pairs after parsing.

[0055] In some embodiments, in step S302, the inconsistent inline style can be differentially parsed to extract the difference attribute. Then, the editing intention can be determined according to the category of the difference attribute.

[0056] In some embodiments, an attribute-intention mapping table can be constructed in advance. The mapping table defines the correspondence between different CSS attributes and abstract editing intentions. Based on the mapping table, the difference attribute can be mapped to a specific editing intention. In an exemplary embodiment, if the difference attribute contains a layout category attribute, it is determined to be an intention related to layout adjustment; if it contains a decoration category attribute, it is determined to be an intention related to style decoration.

[0057] According to some embodiments, the determining the change instruction for the presentation data in accordance with the preset structured format based on the editing intention in step S206 can include: determining the change instruction for the structured description information of the target presentation element based on the editing intention.

[0058] Thus, by specifying the editing intention as a change to a specific target presentation element and its structured description information, the object to be changed can be accurately located and the targeted change instruction can be generated, ensuring the atomicity and accuracy of the backend presentation data update.

[0059] In some embodiments, in step S206, based on the identifier of the target presentation element, the corresponding node in the presentation data can be located, and based on the type of the editing intention, the specific field in the data node that needs to be modified can be determined. Then, a change instruction containing the target node identifier, the target field identifier and the new field value can be constructed. The change instruction is structured to comply with the syntax rules of the preset structured format, so as to be directly parsed and applied to the presentation data.

[0060] According to some embodiments, the structured description information can include a position field of the corresponding presentation element, and the inline style can include a position attribute of the corresponding presentation element. Step S302, determining the editing intention based on the change of the inline style of the target presentation element can include: in response to determining that the position attribute of the target presentation element changes, determining the editing intention as a position moving intention. Step S206, determining the change instruction for the presentation data in the preset structured format based on the editing intention can include: in response to the position moving intention, mapping the value of the position attribute of the target presentation element after the target operation to a target value for updating the position field based on a preset position correspondence relationship.

[0061] Thus, by establishing an accurate mapping mechanism between the front-end position attribute and the back-end position field, the drag operation in the editing environment can be accurately converted into coordinate update of the back-end presentation data, ensuring the consistency of the spatial layout of the presentation element between the logical layer in the back-end and the view layer in the front-end.

[0062] In some embodiments, the position field refers to a parameter defined in the preset structured format for determining the geometric position of the element in the canvas. In an exemplary embodiment, the position field can include a horizontal coordinate field, a vertical coordinate field, a rotation angle field and other fields describing position information.

[0063] In some embodiments, the position attribute in the inline style refers to a style attribute in the page description data of the web editing environment for controlling the rendering position of the element. In an exemplary embodiment, the position attribute can include a left margin attribute (left), a top margin attribute (top), a transform attribute and other attributes describing position information in Cascading Style Sheets (CSS).

[0064] In some embodiments, the position attribute value change can be detected by comparing the inline styles of the target presentation element before and after the target operation. If the position attribute value change is detected, or the change exceeds a preset anti-shake threshold, the editing intention can be determined as a position moving intention.

[0065] In some embodiments, the preset position correspondence defines a conversion logic between the front-end visual coordinates and the back-end logical coordinates. Considering that the canvas rendering size of the web page editing environment can be inconsistent with the standard page size defined in the back-end presentation data, the preset position correspondence can also define a scaling conversion logic between the two coordinate systems.

[0066] In an example embodiment, if the standard page width defined in the back-end presentation data is 1920 logical units, and the current canvas rendering width of the front-end web page editing environment is 960 physical pixels, the preset position correspondence includes a coordinate mapping coefficient of 2:1. When detecting that the element is moved by 10 pixels in the front-end, based on the correspondence, the system will convert it to a change of 20 logical units in the back-end coordinate system. Thus, the preset position correspondence can automatically eliminate the coordinate deviation caused by the front-end view scaling or device resolution difference, accurately restore the pixel-level displacement to the logical coordinate change relative to the standard page, thereby ensuring the typesetting accuracy and consistency when editing on different terminal devices.

[0067] According to some embodiments, the structured description information can include a basic template style field and a custom style field of the corresponding presentation element, and the inline style can include an appearance style attribute of the corresponding presentation element. Step S302, determining the editing intention based on the change of the inline style of the target presentation element can include: in response to determining that the appearance style attribute of the target presentation element has changed, determining the editing intention as an appearance style override intention. Step S206, determining the change instruction for the presentation data conforming to the preset structured format based on the editing intention includes: in response to the appearance style override intention, determining the change instruction as rewriting the value of the custom style field based on the value of the appearance style attribute of the target presentation element after the target operation, and retaining the value of the basic template style field.

[0068] Thus, by constructing a double-layer structure of the basic template style and the custom style on the presentation data in the back-end, and storing the user's appearance modification to the custom style field, the decoupling of user personalization editing and global template style is realized. This mechanism ensures that when the presentation subsequently changes the global theme or applies AI intelligent beautification, it can distinguish and retain the user's specific modification intention, avoid the global operation from covering the user's personalized settings, and improve the flexibility and stability of the presentation data processing.

[0069] In some embodiments, the base template style field refers to a field in the preset structured format for referencing a global theme, a template class name, or a default style. The value of this field is usually determined by the current document theme. The custom style field refers to a field in the preset structured format for storing style properties manually overridden by the user. In one example embodiment, the custom style field can include an object field named customStyle or userOverrides. The appearance style property can refer to an inline style that affects the visual decoration of an element, which is different from the inline style property that affects the position of the layout.

[0070] In some embodiments, when a change in an appearance-related property in an inline style is detected in the web editing environment, the change can be identified as an attempt by the editor to override the default style of the current template. When generating the change instruction, the system does not modify the base template style field, but extracts the changed appearance style property value, formats it as a key-value pair, and writes or updates the corresponding custom style field.

[0071] In one example embodiment, if the user modifies the title color to red, the system will update the custom color field in the structured description information of the title element, while keeping the referenced base theme color configuration unchanged. During subsequent rendering, the rendering engine can preferentially apply the value in the custom style field.

[0072] According to some embodiments, the appearance style property can include at least one of font, font size, color, and background content.

[0073] In some embodiments, the font property can correspond to a font family definition in the web editing environment, the font size can correspond to a size value of the text, the color can correspond to a foreground color value (such as a hexadecimal color code or an RGB value) of the text or graphics, and the background content can correspond to a background color, a background image, or a background gradient style of the element. After identifying a change in any of the above properties, it can be mapped to a corresponding custom style field change.

[0074] According to some embodiments, each of the plurality of presentation elements can have a corresponding identifier. The step S302 of comparing the target page description data and the initial page description data to determine the edit intention can include (not shown in the figure): a step S3021 of matching the identifiers of the presentation elements in the initial page description data with the identifiers of the presentation elements in the target page description data; and a step S3022 of determining the edit intention as an element addition intention in response to detecting an added presentation element in the target page description data that does not carry an identifier. The step S206 of determining the change instruction for the presentation data in the preset structured format based on the edit intention can include: determining the change instruction as a structured description information creation instruction for creating structured description information corresponding to the added presentation element in the presentation data in response to the element addition intention.

[0075] Thus, by introducing the identifier matching mechanism, the existing elements in the webpage editing environment and the elements newly created by the user can be accurately distinguished. By using the absence of the identifier as the basis for determining the newly added element, the front-end addition operation can be synchronized to the structure creation operation in the back-end presentation data, so that the target operation can be accurately converted to the modification of the presentation data, and the modified presentation data can accurately reflect the edit intention of the target operation.

[0076] In some embodiments, the identifier can be a globally unique identifier assigned to each presentation element when the presentation data is created, which can be a digital ID, a string, or other forms. When the presentation data is converted into the initial page description data, the identifier is written into the attribute of the corresponding view element. In an exemplary embodiment, the identifier can be stored as a custom style variable in the inline style.

[0077] In some embodiments, in the step S3021, all presentation elements in the target page description data can be traversed. For each element, it can be checked whether it contains a valid identifier attribute. If an element contains an identifier, the corresponding original element can be found in the initial page description data according to the identifier.

[0078] In some embodiments, in step S3022, if a presentation element is detected without carrying an identifier in the target page description data, it indicates that the element is not originated from the initial presentation data, but is added in the editing process by copy-paste or toolbar insertion, etc. At this time, the editing intention can be determined as an element addition intention. In response to the element addition intention, the current attributes of the added presentation element in the web editing environment can be parsed, including position, size and content information. Subsequently, a new data object, i.e. structured description information, can be generated based on the specification of the preset structured format, and a new unique identifier is assigned to the new object. The change instruction is used to indicate that the newly created data object is added to the presentation data.

[0079] According to some embodiments, a specific presentation element in the plurality of presentation elements can be bound with an event listener. Step S204, in response to detecting a target operation on the plurality of presentation elements, obtaining target page description data describing the web editing environment after the target operation can include: in response to the event listener listening to a discrete editing action for the specific presentation element, extracting local page description data corresponding to the specific presentation element from the web editing environment as the target page description data.

[0080] Thus, by local data extraction based on event listening, fine-grained capture of the target operation is achieved, avoiding full-scan and full-data transmission of the entire web environment after each operation, thereby reducing the computational resource consumption of data processing and improving the real-time performance and system performance of the editing response.

[0081] In some embodiments, the event listener can be a program interface running in the web editing environment for monitoring specific user interaction events. The discrete editing action can be an editing interaction with a clear start and end point, such as mouse drag end, keyboard key up, etc., which is different from continuous intermediate state. The local page description data can be a data segment describing the specific presentation element and its attributes, without data of other unchanged elements in the page.

[0082] In some embodiments, when a presentation element is drawn in the web editing environment, a corresponding event listener can be registered for the element according to its type. For a movable element, a listener can be registered for a mouse up event or a touch end event; for a text edit box, a listener can be registered for a focus out event. When the user finishes the editing operation and triggers the corresponding event, the listener captures the target node that triggers the event, and then can directly read the current attribute information of the target node. In an exemplary embodiment, the inline style string or the external HTML structure of the DOM node can be read, and the data segment is extracted as the target page description data for subsequent difference comparison module to only compare the segment.

[0083] According to some embodiments, the initial page description data can include a non-closed data segment in streaming. Step S203, drawing a plurality of presentation elements in the web editing environment based on the initial page description data can include (not shown in the figure): step S2031, injecting the non-closed data segment into a virtual container in the web editing environment to complete the non-closed data segment into a renderable node; and step S2032, drawing the renderable node in the visible area in the web editing environment.

[0084] Thus, by using the virtual container to buffer and complete the non-closed or incomplete data generated in the streaming process, fault-tolerant processing of streaming data is achieved, and page structure disorder caused by directly rendering incomplete code is avoided, thereby supporting progressive loading and display of presentation content under the premise of ensuring rendering stability, improving the accuracy of displayed content, the stability of the display process, and enhancing the user experience.

[0085] In some embodiments, the non-closed data segment can be a page description string received in blocks during streaming, which does not yet contain complete start and end tags. For example, the non-closed data segment can be a piece of HTML element that has not yet transmitted the end tag. The virtual container can be a memory object or a hidden element created in the web editing environment that is not connected to the current visible document tree, such as a document fragment object or a container node set to invisible. The renderable node can be a document object model node that has been parsed and corrected to have complete closed structure and can be correctly parsed by the browser engine.

[0086] In some embodiments, a data stream connection with the server can be established, and a text stream of page description data can be continuously received. When a data block is received, it can be appended to the internal hypertext markup language attribute of the virtual container. Using the fault-tolerant parsing mechanism at the bottom of the web editing environment, the virtual container automatically closes the incomplete tags or corrects the structure, thereby converting the text stream into a DOM tree in memory.

[0087] In some embodiments, the node status in the virtual container can be monitored in real time. When a complete top-level element node is generated in the virtual container, the renderable node can be removed from the virtual container and mounted under the root node of the visible area of ​​the web page editing environment, thereby enabling real-time display of the content on the screen.

[0088] According to some embodiments, presentation data can be generated from a large model based on user instructions. For example... Figure 4 As shown, the method for processing presentation data may include: step S408, after updating the presentation data using change instructions, receiving optimization instructions for the updated presentation data; and step S409, calling the large model to execute the optimization instructions based on the updated presentation data to generate optimized presentation data that conforms to the editor's intent. It is understood that... Figure 4 The operations and effects of steps S401-S407 can be referred to the above text. Figure 2 The descriptions of steps S201-S207 are not repeated here.

[0089] Therefore, by using the updated presentation data, which integrates user editing intentions, as input to the large model again, a closed-loop iterative mechanism for generation, editing, and re-optimization is constructed. This mechanism ensures that the results of manual adjustments are inherited and preserved in subsequent human-computer collaborative presentation iterations, avoiding the overwriting of user-personalized modifications by secondary generation operations. This improves the flexibility, stability, and accuracy of the final optimized presentation data obtained through human-computer collaborative presentation generation.

[0090] In some embodiments, the optimization instruction can be a control command issued by a user or intelligent agent, designed to optimize the current presentation data. This instruction can instruct a large model to make overall style adjustments, layout optimizations, or content polishing to the presentation data, and can be in natural language form. The large model can be a deep learning model or a generative artificial intelligence model with long text understanding capabilities and the ability to process and generate presentation text data.

[0091] In some embodiments, user input optimization instructions can be received via an interactive interface. Upon receiving the optimization instructions, the updated presentation data from step S207 can be directly provided to the large model, or converted into a data format readable by the large model before being provided to it. Furthermore, the optimization instructions themselves can also be provided to the large model.

[0092] In some embodiments, the large model is configured to follow specific constraints in the structured data when performing the generation task. Since the user's editing intention has been inversely mapped and solidified into specific fields in the presentation data (e.g., a position field or a custom style field), the large model can identify the user's intention represented by these fields when parsing the input data. When generating the optimized presentation data, the large model will make optimization adjustments to the parts not modified by the user, while keeping the fields representing the user's intention unchanged or only fine-tuning them under the premise of being compatible with the user's intention, thereby outputting new data that conforms to the editing intention.

[0093] According to another aspect of the present disclosure, a processing apparatus for presentation data is provided. As shown in Figure 5 The apparatus 500 includes a first obtaining unit 510 configured to obtain presentation data based on a preset structured format, the presentation data including structured description information of each of a plurality of presentation elements; a converting unit 520 configured to convert the presentation data into a page description format supported by a web editing environment to obtain initial page description data; a rendering unit 530 configured to render the plurality of presentation elements in the web editing environment based on the initial page description data; a second obtaining unit 540 configured to obtain target page description data describing the web editing environment after a target operation on the plurality of presentation elements in response to detecting the target operation; a comparing unit 550 configured to compare the target page description data and the initial page description data to determine an editing intention; a determining unit 560 configured to determine a change instruction for the presentation data conforming to the preset structured format based on the editing intention; and an updating unit 570 configured to update the presentation data using the change instruction.
