The first terminal device 101, the second terminal device l 02, the third terminal device l 03 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop and desktop computers, and the like.

The server 105 may be a server providing various services, such as a background management server (merely an example) providing support for content browsed by the user with the first terminal apparatus 101, the second terminal apparatus 102, the third terminal apparatus 103. The background management server may analyze and process the received data such as the user request, and feed back the processing result (e.g., the web page, information, or data obtained or generated according to the user request) to the terminal device.

It should be noted that, the method for generating a presentation provided in the embodiments of the present disclosure may be generally executed by the first terminal device 101, the second terminal device 102, and the third terminal device 103. Accordingly, the presentation generating device provided in the embodiments of the present disclosure may also be provided in the first terminal device 101, the second terminal device 102, and the third terminal device 103.

Alternatively, the method for generating a presentation provided by the embodiments of the present disclosure may be generally performed by the server 105.

In the technical scheme of the disclosure, the related processes of collecting, storing, using, processing, transmitting, providing, disclosing, applying and the like of the personal information of the user all conform to the regulations of related laws and regulations, necessary security measures are adopted, and the public order harmony is not violated.

In the technical scheme of the disclosure, the authorization or consent of the user is obtained before the personal information of the user is obtained or acquired.

Fig. 2 schematically illustrates a flowchart of a method of generating a presentation according to an embodiment of the present disclosure.

As shown in fig. 2, the method 200 includes operations S210 to S240.

In operation S210, a preview page and an initial association relationship are generated according to the theme of the presentation.

In operation S220, a change operation performed on at least one initial operation instruction in response to the target object.

In operation S230, a changed text line is determined from the plurality of second text lines according to the initial association relationship and the target association relationship.

In operation S240, a rendering operation is performed on the changed text line based on the preview page, and a target presentation is generated.

According to embodiments of the present disclosure, the theme of the presentation may include theme content and theme style. The theme content and the theme style may be obtained based on a selection operation or an input operation of the user. For example: the topic content and topic style may be obtained from the session content by conducting a demand communication session with the user prior to presentation generation. The topic content and the topic style can also be obtained by configuring page buttons of different topic content and topic style based on the selection of the page buttons by a user.

According to embodiments of the present disclosure, the theme style and the theme content may be in one-to-one correspondence, for example: the subject matter is a "report of staff," and the subject style corresponding to the "report of staff" may be a style that is relatively single in color and more rigorous in text description.

According to an embodiment of the present disclosure, a preview page is generated by executing a plurality of initial operation instructions corresponding to a theme. For example: the preview page may include a plurality of first text lines corresponding to the theme, each first text line may correspond to an initial operation instruction, the initial operation instruction may include text content and text attributes corresponding to the script line, and the script attributes may include font size, font color, and the like.

According to an embodiment of the present disclosure, the plurality of first text lines corresponding to the subject may be sub-subjects associated with the subject, or may be material text corresponding to the subject. For example: the theme may be "caricature" and the sub-theme may include: cartoon summaries, cartoon creation flows, cartoon creation skills, and the like. In the generated preview page, the theme "caricature" may be presented as a primary title in the first row of the preview page. The subtopics "cartoon overview", "cartoon creation flow" and "cartoon creation skill" may be presented as secondary titles in sequence in the second row through the fourth row of the preview page.

In the related art, the corresponding of the theme and the text material, and the font color, font size, animation effect and the like displayed in the final presentation are configured in the initial operation instruction, so that the phenomenon of serious templating is unavoidable in the automatic generation of the presentation.

Therefore, the embodiment of the disclosure visually displays the templated initial operation instruction on the terminal equipment, so that a user can change unsatisfactory text content or text display effect to meet the personalized requirements of the user.

According to the embodiment of the disclosure, since each first text line can correspond to one initial operation instruction, the changed target operation instruction can be obtained by changing the initial operation instruction corresponding to the text line.

For example: in the preview page, the subtopic "comic creation flow" and "comic creation skill" are both content related to comic creation, and the user can modify the content of the subtopic "comic creation flow" to "comic creation flow and skill" and delete the atomic topic "comic creation skill" by changing the initial operation instruction. The operations of adding, deleting, modifying and the like of the text content or the text attribute can be realized based on the change of the initial operation instruction for the text corresponding to the sub-theme, and are not repeated herein.

In different application scenes, the number of pages of the presentation is also different, and for the presentation with a large number of pages, a large amount of hardware resources are required to be occupied when rendering all the pages. However, when the user modifies the content or the display effect in the presentation, most of the pages are only a small part, so that the modified text lines can be determined from the second text lines according to the initial association relationship and the target association relationship, and the rendering operation is only performed on the modified text lines when the target presentation is generated, thereby achieving the effect of reducing the occupancy rate of hardware resources.

According to embodiments of the present disclosure, the initial association relationship may characterize a grammatical relationship between a plurality of words used to compose a plurality of first text lines of the preview page. When the preview page is generated, the initial association relationship can be obtained by marking the part of speech of each word in each text line based on the grammar relationship between the words in the text line, so as to realize the structuring of the text line. The structured text lines can be text in a markdown format, grammar logic between words in the text lines can be clarified, grammar logic between the text lines can be clarified, so that text contents can be better organized when a presentation is generated, and simultaneously, unique identification div labels can be configured for each text line, so that changed text lines can be quickly determined.

Similarly, after the changed target operation instruction is executed, a target association relationship may be generated for a plurality of second text lines after the change based on the same principle, which is not described herein. The target association characterizes a grammatical relationship among a plurality of words used to compose a plurality of second lines of text, the plurality of second lines of text including altered lines of text and unaltered lines of text corresponding to the target manipulation instruction.

According to the embodiment of the disclosure, the first text line and the second text line can be texts in a markdown format, so that the initial association relationship and the target association relationship can be analyzed and processed based on a diff algorithm to obtain changed text lines. And based on the preview page, performing single-line rendering on the changed text line to generate a target presentation.

The present disclosure provides a method for generating a presentation, which generates a preview page according to the theme of the presentation. Then, the changed target operation instruction can be obtained based on the change operation of the target object to the initial operation instruction. And the text line in the preview page is changed by executing the changed target operation instruction, so that personalized editing and updating of the preview page are realized according to personalized requirements of different users. And finally, determining changed text lines from a plurality of second text lines according to the initial association relationship and the target association relationship, and based on the preview page, only performing rendering operation on the changed text lines to generate a target presentation, so that repeated rendering operation on unchanged text lines is not needed, occupation of hardware resources by repeated rendering is reduced, and generation efficiency of the target presentation is effectively improved.

According to an embodiment of the present disclosure, generating a preview page and an initial association according to a theme of a presentation may include the following operations: according to the theme of the presentation, determining candidate texts and a target operation template from a text library, wherein the target operation template comprises a plurality of initial operation instructions corresponding to the theme; processing the theme and the candidate text of the presentation by executing a plurality of initial operation instructions to generate a plurality of first text lines; word segmentation is carried out on a plurality of first texts to obtain an initial association relation; and performing rendering operation on the first texts based on the initial association relation to generate a preview page.

Fig. 3 schematically illustrates a schematic diagram of generating a preview page from a theme of a presentation in accordance with an embodiment of the present disclosure.

As shown in fig. 3, in an embodiment 300, the subject matter of the presentation may be a "read report" 301, from which candidate text and target operation templates 320 may be determined from a text library. The sub-topics associated with the "read report" 301 may be analyzed by topic, such as: the subtopics may include "background knowledge" 3011, "primary content and persona analysis" 3012, and "personal insight and thinking" 3013. Each target text corresponding to each sub-topic may be determined from the candidate texts. For example: target text T corresponding to background knowledge 3011 ₁ 3021. Target text T corresponding to "main content and character analysis" 3012 ₂ 3022 and target text T corresponding to "personal insight and thought" 3013 ₃ 3023。

According to embodiments of the present disclosure, a text content outline 310 may be composed of topics, sub-topics, and target text corresponding to the sub-topics. The text content outline 310 may be visible to the user, for example: the text content outline page may be formed based on the text content outline 310, and the user may implement modification of the text content outline based on editing operations on the text content outline page.

According to an embodiment of the present disclosure, a plurality of initial operation instructions corresponding to a theme are included in the target operation template 320. To facilitate user operation, the initial operation instructions may be configured to correspond one-to-one with each first text line in the preview page. The initial operation instruction may reference a div tag of the first text line configuration to identify the location of the text line. Since there is a hierarchical relationship between the topics, sub-topics and target text in the text content outline 310, for example: the subject belongs to a primary title, the sub-subject belongs to a secondary title, and the target text belongs to a body.

Thus, indexes may be built based on the hierarchical relationship between text lines, each of which may correspond to a first text line. The index m may correspond to the content of the primary title, the index m-i may correspond to the content of the secondary title related to the primary title having an index m, and the index m-i-j may correspond to the content of the body related to the primary title having an index m and the secondary title having an index i.

For example: in the target operation template, "index 1: the operation instruction a "corresponds to the" reading report "301. "index 1-1: the operation instruction a-1 "corresponds to" background knowledge "3011. "index 1-1-1: the operation instruction a-1-1' corresponds to the target text T ₁ "3021. And so forth, they are not described in detail herein.

According to an embodiment of the present disclosure, the initial operation instruction may include text content, a presentation position of the text in the presentation, a presentation color, a font size, a dynamic effect, and the like. Accordingly, a plurality of first text lines may be generated by associating a theme of the presentation, a plurality of sub-themes, and a plurality of target texts by executing an initial operation instruction corresponding to each first text line.

According to the embodiment of the disclosure, the initial association relationship can be obtained by word segmentation and part-of-speech tagging of a plurality of first text lines based on the grammatical relationship between words in each first text line, so that grammar logic in the text lines and between the text lines is ensured to accord with the description mode of natural language.

According to an embodiment of the present disclosure, a preview page is generated by performing a rendering operation on a plurality of first text lines in a predetermined rendering order based on an initial association relationship. The predetermined rendering order may be configured based on actual requirements of the application scene, and is not specifically limited herein, for example: the first preview page 330 may be generated by sequentially rendering text corresponding to the first-level title or sequentially rendering text corresponding to the last-level title. In the first preview page 330, the subject "read report" is preceded by a black, solid identifier, and the font is bolded and the font size is larger. The subtopic "background", "primary content and character analysis", "personal insight and thinking" is preceded by a hollow identifier and the font is not bolded with a smaller font size.

After the first preview page 330 is generated, the user may modify the content of the preview page and the presentation effect based on the change operation to the initial operation instruction.

Fig. 4 schematically illustrates a schematic diagram of text content modification to a preview page in accordance with an embodiment of the present disclosure.

As shown in fig. 4, a second preview page 410, a first set of operational instructions 420, and a first target presentation 430 may be included in the embodiment 400. The second set of operation instructions 420 may include changed target operation instructions and unchanged initial operation instructions.

According to the embodiment of the disclosure, the target object (namely, a user) can select an initial operation instruction to be changed according to the index tag, and can also position the initial operation instruction to be changed through the selection operation of the text line to be changed.

For example: the target object may select the text line 411 to be changed in the preview page, and automatically locate the operation instruction a-2412 corresponding to the text line 411 to be changed according to the index tag "index 1-2" of the text line to be changed.

Since the initial operation instruction is visualized to the target object, the operation instruction to be changed corresponding to the text line to be changed can be determined according to the position of the text line to be changed. For example: the position of the text line to be changed may be the position of the text line corresponding to the index tag "index 1-2", and the operation instruction to be changed may be determined to be the operation instruction a-2412.

According to an embodiment of the present disclosure, the target object may directly change the operation instruction a-2 to obtain the operation instruction a-2'422, for example: the text content in the operation instruction to be changed can be changed, so that the target operation instruction is further changed.

For example: the text content in the operation instruction a-2412 to be changed may be "main content and character analysis", and the text content in the operation instruction a-2'422 may be "main content and core character analysis" after the change operation.

According to an embodiment of the present disclosure, generating the target association relationship by executing the changed target operation instruction may include the following operations: determining a text line to be changed from a plurality of first text lines in the preview page according to the position of the text line to be changed; based on the text content to be changed, carrying out content change on the text line to be changed, and generating a changed text line and a first association relation; and generating a target association relation according to the first association relation and the second association relation.

By executing the target operation instruction, the main content and core character analysis of the changed text line can be generated, and the part corresponding to the text content of the changed text line in the initial association relationship is updated to obtain the target association relationship. The target association relationship may include: the first association relationship and the second association relationship. The first association relation characterizes grammar relations among a plurality of words corresponding to the changed text line; the second association represents a grammatical relation among a plurality of words corresponding to the unchanged text lines in the initial association.

Then, by comparing the initial association relationship and the target association relationship, a changed text line is determined, and the changed text line 'main content and core character analysis' 431 is rendered in a single line, so as to generate a first target presentation 430.

According to the embodiment of the disclosure, the modification of the initial operation instruction can not only realize the modification of the text content, but also realize the modification of the text attribute, for example: and carrying out attribute change on the text line to be changed based on the attribute to be changed, and generating a changed text line.

Fig. 5 schematically illustrates a schematic diagram of text attribute modification of a preview page according to an embodiment of the present disclosure.

As shown in fig. 5, a third preview page 510, a second set of operational instructions 520, and a second target presentation 530 may be included in the embodiment 500. Included in the second set of operation instructions 520 are target operation instructions "index 1-3: operation instruction a-3' "522 and initial operation instruction" index 1-1 "corresponding to the unchanged text line: operation instructions a-1 "and" index 1-2: operation instruction a-2).

According to an embodiment of the present disclosure, the text line to be changed selected by the user may be "heart experience" 511, and the initial operation instruction corresponding to "heart experience" 511 is "index 1-3: operation instruction a-3). The text attribute that is appreciated in the operation instruction a-3 may be a presentation attribute corresponding to the secondary title, for example: font color, font size, style of identifier in front of the font, etc.

According to the embodiment of the disclosure, the target object can directly change the operation instruction a-3 to obtain the operation instruction a-3'522, and obtain the target operation instruction index 1-3: the operation instruction a-3' "is, for example: the attribute information such as the font color, font size, and style of the identifier in front of the font in the original operation instruction a-3 may be changed to the attribute information corresponding to the primary title.

According to the embodiment of the disclosure, by executing the target operation instruction, a changed text line 'mind' can be generated, and a part corresponding to the text content of the changed text line in the initial association relationship is updated to obtain the target association relationship. Then, by comparing the initial association relationship and the target association relationship, a changed text line is determined, and a single-line rendering is performed on the changed text line 'mind and experience' 531, so as to generate a second target presentation 530.

According to the embodiment of the disclosure, the personalized editing operation of the automatically generated preview page is realized by directly changing the initial operation instruction, so that the personalized requirements of different users on the presentation are met, and the user experience is improved. And single-row rendering is realized on the changed text lines, so that the occupation of hardware resources can be reduced.

For the changing operation of the presentation effect of the presentation, for example: font color, font size, dynamic effects, etc., such a modification operation to the attribute is relatively easy to implement. However, the text content is difficult to change, the flexibility of changing the text content is high, and the personalized requirements of users can be met.

Therefore, according to the embodiment of the disclosure, the word segmentation processing is performed on the words of the text lines to obtain the grammar relationship between the words, so that the flexibility of changing operation can be improved. Then, the position of the changed text line is obtained by comparing the initial association relationship with the target association relationship; and determining a changed text line from the plurality of second text lines according to the position of the changed text line. To reduce repetitive operations in the rendering process.

According to an embodiment of the present disclosure, a first relationship tree may be generated according to an initial association relationship; generating a second relation tree according to the target association relation; comparing the plurality of first nodes with the plurality of second nodes to determine changed nodes; and determining the position of the changed text line according to the attribute information of the changed node.

According to an embodiment of the present disclosure, a first relationship tree includes a plurality of first nodes therein, the plurality of first nodes corresponding to a plurality of words for composing a plurality of first text lines; the second relationship tree includes a plurality of second nodes corresponding to a plurality of words constituting a plurality of second text lines.

For example: each node in the first and second relationship trees may be traversed layer by layer starting from the root node, resulting in a changed node.

Since the changed node generally affects the node to which it is connected, there is no effect on other nodes. Thus, a relationship tree may be traversed sub-tree by sub-tree, each sub-tree may correspond to a paragraph of text. The hash value of the root node of the subtree may be hashed based on text content and text attributes for a plurality of text lines that make up the text paragraph. When traversing each subtree root node, it can be determined whether the text paragraph has changed by comparing the hash values of the root nodes. If no change occurs, it is not necessary to traverse the leaf nodes down again. If a change has occurred, the leaf node is traversed down. Thereby improving the data processing efficiency of the comparison process.

According to the embodiment of the disclosure, since the initial association relationship and the target association relationship are both constructed based on the grammatical relationship between words, and the granularity is smaller, the modification of the content of any text line in the preview page can be effectively identified, and the flexibility of modification operation is improved.

It should be noted that, based on the changing operation of the target object to the initial operation instruction, the obtained text content, text attribute and grammar relation between words in the text line in the target presentation file may update the text library, the target operation template and the processing logic algorithm for generating the preview page by periodically counting the feedback content, so as to improve the satisfaction degree of the user to the preview page.

Fig. 6 schematically illustrates a block diagram of a presentation generating apparatus according to an embodiment of the present disclosure.
