Also, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in a sequence different from that shown here.

[0034] Figure 3Flow chart of a method for generating a presentation in accordance with an embodiment of the present invention, as shown in FIG. Figure 3 As shown, including:

[0035] Step 301: Divide the outline content into two or more groups according to the node level according to a preset strategy;

[0036] In an exemplary embodiment, the outline content is divided into two or more groups according to a preset strategy based on the node level, including:

[0037] Divide the outline contents included in the title node, time node, author node and the first picture node sorted after the title node into groups for generating the PPT cover;

[0038] Divide the outline contents included in all first-level outline nodes into groups for generating PPT directory pages;

[0039] Divide the outline contents included in each first-level outline node into groups for generating PPT chapter pages corresponding to the first-level outline nodes;

[0040] The outline contents included in the subnodes greater than a preset level in each first-level outline node are divided into groups for generating PPT text pages corresponding to the subnodes.

[0041] The sub-nodes in the embodiment of the present invention may include: a second-level node, a third-level node, a fourth-level node, etc.

[0042] In an exemplary embodiment, before dividing the outline content into two or more groups according to a preset strategy, the method further includes: parsing the outline content with reference to relevant technologies to determine the nodes included in the outline content and the level of each node.

[0043] Step 302: Calculate the feature vector of each group obtained by the division; wherein the feature vector is used to represent the page structure of the PPT page generated by the outline content contained in the group;

[0044] It should be noted that the feature vector calculation method of the embodiment of the present invention may include existing methods in the relevant technology, and the feature vector is used to identify the amount of text contained in the title, text, graphic group, graphic and text group, etc. in the PPT page, the image size, resolution, etc.

[0045] In an exemplary embodiment, before calculating the feature vectors of each group obtained by division, the method of the embodiment of the present invention further includes:

[0046] When the sub-node included in the group is located at the second end of the outline content and there is only one sub-node, the outline content of the sub-node and the sub-node of the sub-node at the next level are merged into one group; and / or,

[0047] When the sub-node included in the group is located at the end of the outline content and there is only one sub-node, the outline content of the sub-node and the sub-node of the previous level of the sub-node are merged into one group.

[0048] In an exemplary embodiment, the embodiment of the present invention calculates the feature vector of each group obtained by division, including:

[0049] For each group obtained by the division, determine the page structure of the PPT page generated by the outline content contained in the group;

[0050] According to the determined page structure, feature calculations are performed on the page components contained in the page structure to obtain feature vectors of each group;

[0051] Among them, the page structure includes: the page composition included in the PPT page; the page composition includes: basic components and / or component components composed of more than one basic components.

[0052] It should be noted that different page components, the amount of text contained in the page components, or information such as image size and resolution can be represented by feature vectors obtained through feature calculation.

[0053] In an exemplary embodiment, the basic components in the embodiment of the present invention include one or any combination of the following: title, picture, text; based on the above basic components, the component assembly in the embodiment of the present invention may include one or any combination of the following: icon group, image and text group, picture group, text group, title group; wherein the icon group may consist of more than one icon; the image and text group may consist of more than one image and more than one text; the text group may consist of more than two texts; the title group may consist of more than two texts;

[0054] It should be noted that after determining the page structure, the characteristic vector can be calculated by referring to the relevant technology; for example, the existing method of determining the grouping is that the page structure of the PPT page generated by the outline content contained in the grouping is: a title with a text volume of a, a graphic group consisting of three main texts with text volumes of x, y and z respectively, and a picture with a pixel size of m*n; based on the above page structure, the characteristic vector is calculated by the existing method in the relevant technology.

[0055] In an exemplary embodiment, when determining the page structure, for the group obtained by group merging, the outline content of the terminal node can be used as the main text or subtitle; for example, when there is only one child node at the end, the outline content of the child node is used as the subtitle or main text; when there are only multiple child nodes at the end, the outline content of each terminal child node is used as the main text, so that the diagram group can be constructed;

[0056] Step 303: Determine a presentation PPT template for filling the outline content contained in each group according to the calculated characteristic vector of each group;

[0057] In an exemplary embodiment, the embodiment of the present invention determines a PPT template for filling the outline content contained in each group, including:

[0058] Determine the feature vector of each pre-stored PPT template;

[0059] For each group, the feature vector of the group is compared with the feature vector of the PPT template, and the PPT template whose feature vector satisfies similar conditions to the feature vector of the group is used as the PPT template for filling the outline content contained in the group. The PPT template for filling the outline content contained in the group determined by the embodiment of the present invention according to the feature vector can reasonably and effectively fill the outline content contained in the group; for example: the content contained in the group is: a title with a text volume a, a graphic group consisting of three texts with a text volume of x, y and z respectively, and a picture with a pixel size of m*n; after calculating the feature vector according to the outline content contained in the above group, the determined PPT template generally includes: the same composition and the feature vectors of each composition are relatively similar, that is, the PPT template for filling the outline content of the above group can be filled with a title with a text volume close to or equal to a, a graphic group consisting of three texts with a text volume close to or equal to x, y and z respectively, and a picture with a pixel size close to or equal to m*n.

[0060] Step 304: Fill the outline content contained in each group into the determined PPT template to generate a PPT file.

[0061] After the embodiment of the present invention groups the outline contents according to the node level, a presentation (PPT) template for filling the outline contents contained in each group is determined according to the characteristic vector of the group. In this way, the generated PPT file corresponds to the node level of the outline contents, thereby improving the generation quality and presentation effect of the PPT file.
