Detailed ways

The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the application, but should not be understood as a limitation to the application.

The information file processing method, apparatus, electronic equipment, and computer-readable storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

As shown in Figure 1, the processing method of the information file includes the following steps:

Step 101: Obtain all information files in the target folder.

In the embodiments of the present application, the information file is a file containing the amount of information, and may be a picture file, a text file, and the like. The folder can store the same type of information files at the same time, and can also store different types of files. For example, the folder only stores picture files, or only text files, etc., and the folder can also store picture files and text files, etc. Store at the same time. It should be noted that the embodiments of the present application are described by taking the same type of information files stored in a folder as an example.

For example, assuming that the information file processing method of the embodiment of the present application is applied to a mobile terminal, when the user opens the folder list of the mobile terminal, the absolute path of each folder in the folder list can be obtained first, and the The absolute path to get the files stored in each folder from the storage.

Step 102: Select N target information files from all the information files according to the size of the information contained in the file content, where N is a positive integer.

In the embodiment of the present application, when all the information files in the target folder are obtained, all the information files in the target folder can be identified separately to obtain the amount of information contained in the respective file contents of all the information files. After that, sort all information files according to the order of the amount of information contained in the file content, and select the top N information files from all the information files, and determine the selected top N information files as N target information files.

It should be noted that different file types use different methods for obtaining the amount of information contained in the file content. For example, when the information file is a picture, image recognition technology can be used to obtain the amount of information contained in the file content; when the information file is a text file, text recognition technology can be used to obtain the amount of information contained in the file content. For a specific implementation manner, refer to the description of the subsequent embodiments.

Optionally, in order to allow users to quickly learn the content of the information files in the folder to the maximum extent, when selecting N target information files from all the information files according to the size of the information contained in the file content, all the information files can be determined first The number of files; determine whether the number of files is greater than or equal to the preset threshold; if so, select the preset threshold information files from all the information files according to the size of the information contained in the file content, and set the preset threshold information Files are regarded as N target information files; if not, all information files are regarded as N target information files.

For example, in the embodiment of this application, in order to allow users to quickly learn the contents of the information files in the folder to the maximum extent and prevent the thumbnails from being too small, the preset threshold can be set to 5, that is, the maximum value of N can be 5. , The maximum number of compressed pictures that can be used to generate the cover of the target folder is five, so the maximum number of target information files can be set to 5.

It should be noted that in the embodiment of the present application, if all the information files in the target folder contain the same amount of information, N information files can be randomly selected from these information files as the target information files, or, N information files can also be selected based on certain preset rules. For example, based on the creation time of the file, N information files with the first creation time are selected as the target files.

Step 103: Generate N thumbnails of N target information files.

In the embodiment of the present application, the sequence of the N target information files can be determined according to the size of the information contained in the file content, and the compression size corresponding to the N target information files can be determined according to the sequence of the N target information files , Based on the compression size corresponding to the N target information files, compress the N target information files to generate N thumbnails correspondingly. For example, the sequence of the N target information files can be arranged such that the compressed size of the target information file arranged in the front is larger than the compressed size of the target information file arranged in the back. For example, it is determined that the target information file arranged in the first corresponds to The sizes of the thumbnails are all larger than the sizes of the thumbnails corresponding to the remaining target information files, and the sizes of the thumbnails corresponding to the remaining target information files are all the same.

It should be noted that, depending on the type of the target information file, the method used when generating the thumbnail of the target information file will also be different. For example, when the target information file is a picture, the compression size corresponding to each picture can be directly determined, and then the corresponding picture is compressed based on each compression size to obtain the corresponding thumbnail; and when the target information file is a text file, you need to first After converting text to image, image compression is performed. For specific implementation manners, refer to the description of the subsequent embodiments.

Step 104: Use N thumbnails as cover information of the target folder.

Optionally, based on a preset multi-level thumbnail strategy, N thumbnails are typeset and combined to generate a composite thumbnail, and the composite thumbnail is determined as the cover information of the target folder. It should be noted that the multi-level thumbnail strategy may be preset, and the multi-level thumbnail strategy can be understood as combining multiple thumbnails into a composite thumbnail in a hierarchical manner. For example, the composite thumbnail to be generated can be divided into two parts, such as left and right parts, where the left part occupies a larger proportion than the right part, and the thumbnail with the largest amount of information among the N thumbnails As the left part of the composite thumbnail to be generated, the remaining N-1 thumbnails are arranged in the right part in order of the amount of information contained, so that the composite thumbnail can be composed.

It should be noted that when N is 1, the unique thumbnail can be used as the cover information of the target folder. In the embodiment of the present application, the maximum value of N may be 5, that is, a composite thumbnail composed of up to 5 thumbnails can be used as the cover information of the target folder. For example, suppose the method for processing information files in the embodiment of the present application is applied to a mobile terminal. Taking the mobile terminal’s album gallery as an example, there are 4 folders under it. When the user opens the mobile terminal’s album gallery, each Folder, you can get all the information files in each folder, and according to the size of the information contained in the file content, select 5 target information files from all the information files in each folder, among which, if the folder is When the number of information files is less than 5, all information files in the folder can be used as target information files. After that, thumbnails of the target information file can be generated, and the thumbnails with a large amount of information contained in these thumbnails are used as the main body of the folder cover, and they are arranged on the left part of the folder cover, and the remaining thumbnails are divided equally Right space. For example, as shown in Figure 2(a), there are more than 5 information files stored in this folder. In this way, 5 information files can be selected from this folder, and their thumbnails can be combined into composite thumbnails as the folder The cover of the cover, where the thumbnail with the largest amount of information among the 5 thumbnails can occupy the left side of the cover, and the remaining 4 thumbnails equally divide the space on the right side of the cover; as shown in Figure 2(b), this folder Two information files are stored under the file. In this way, these two information files can be used as target information files, and their thumbnails can be combined into composite thumbnails as the cover of the folder. Among them, the amount of information contained in the two thumbnails can be The largest thumbnail occupies the left side of the cover, and the smaller thumbnail occupies the space on the right side of the cover; as shown in Figure 2(c), if only one information file is stored in the folder, the thumbnail of the information file can be As the cover of the folder directly, the thumbnail occupies the entire space of the cover of the folder; as shown in Figure 2(d), the folder stores 4 information files, which can be used as target information files , Compose its thumbnails into composite thumbnails as the cover of the folder. Among them, the thumbnail with the largest amount of information among the 4 thumbnails can occupy the left side of the cover, and the remaining 3 thumbnails can evenly divide the right side of the cover space. As a result, performance can be optimized through multi-level thumbnails, so that composite thumbnails composed of multiple thumbnails can be quickly presented, ensuring system operating efficiency.

It should also be noted that, in an embodiment of the present application, if there are no files in the target folder, the default icon of the folder can be used as the cover of the target folder.

According to the information file processing method of the embodiment of the application, all information files in the target folder can be obtained; afterwards, all information files in the target folder are obtained; according to the size of the information contained in the file content, all information files Select N target information files, where N is a positive integer; generate N thumbnails of N target information files; and use N thumbnails as cover information of the target folder. Therefore, through the artificial intelligence picture recognition technology, the most representative files are intelligently identified from the folder, and the thumbnails corresponding to these files are used as the cover of the folder, so that the cover of the folder has the subjectivity and makes the user You can quickly learn the content of the information files in the folder by viewing the folder cover, which improves efficiency and improves user experience.

In order to improve user experience and ensure the usability and feasibility of this application, optionally, in an embodiment of this application, upon receiving a view instruction for the directory where the target folder is located, the size of the display area of the target folder may be determined , And based on the size of the display area, present the cover information of the target folder in the corresponding display area. For example, when a user opens the directory where the target folder is located, all target folders under this directory are displayed on the interface. It is understandable that each target folder occupies a certain interface area for display. According to the size of the display area, The cover information of the target folder is displayed in this area.

It should be noted that, depending on the file type, the method for obtaining the amount of information contained in the file content used will also be different. Two different implementation methods will be given below in conjunction with Fig. 3 and Fig. 4.

Fig. 3 is a flowchart of a method for processing an information file according to a specific embodiment of the present application. It should be noted that the processing method of the information file in the embodiment of the application is described with the information file as a picture, that is, the processing method of the information file in the embodiment of the application is applied to the picture folder scene, where, The target folder can be a picture folder. As shown in Figure 3, the processing method of the information file may include:

Step 301: Obtain all pictures in the picture folder.

Step 302: Obtain N target pictures from all pictures according to the size of the information contained in the file content, where N is a positive integer.

Optionally, extract pixel information in all pictures, calculate the variance value of the gray values of all pictures according to the pixel information in all pictures, and determine the variance value of all pictures as their respective files The amount of information contained in the content. After that, all pictures can be sorted according to the order of the amount of information contained in the file content, and the top N pictures are selected from all pictures, and the top N pictures are sorted The picture is determined to be N target pictures.

As an example, perform grayscale processing on the pictures in the folder to obtain the grayscale values in the pictures, and then calculate the grayscale variance values of the pictures according to the grayscale values in the pictures. Then, based on the gray-level variance value of the pictures, all pictures are sorted, and the top N pictures are selected from all pictures, and the top N pictures can be used as N target pictures.

Step 303: Determine the sequence of N target pictures according to the size of the information contained in the file content.

Step 304: Determine the compression size corresponding to the N target pictures according to the sequence of the N target pictures.

Step 305: Compress the N target pictures based on the compression size corresponding to the N target pictures to generate N thumbnails.

Step 306: Use N thumbnails as cover information of the picture folder.

Optionally, based on a preset multi-level thumbnail strategy, N thumbnails are typeset and combined to generate a composite thumbnail, and the composite thumbnail is determined as the cover information of the picture folder.

According to the information file processing method of the embodiment of the present application, all the pictures in the picture folder can be acquired, and then, according to the size of the information contained in the file content, N target pictures are selected from all pictures to generate N target pictures N thumbnails, and N thumbnails are used as the cover information of the picture folder. As a result, through artificial intelligence picture recognition technology, intelligently identify the most representative pictures from the picture folder, and use the thumbnails corresponding to these pictures as the folder cover, so that the cover of the picture folder has the subjectivity. This allows users to quickly learn the content of the pictures in the folder by viewing the cover of the folder, which improves efficiency and improves user experience.

Fig. 4 is a flowchart of a method for processing an information file according to another specific embodiment of the present application. It should be noted that the processing method of the information file in the embodiment of the application is described in the case that the information file is a text file, that is, the processing method of the information file in the embodiment of the application is applied to the folder where the text is stored. , Where the target folder is a text folder. As shown in Figure 4, the processing method of the information file may include:

Step 401: Obtain all text files in the text folder.

Step 402: Select N target text files from all text files according to the amount of information contained in the file content, where N is a positive integer.

Optionally, perform text recognition on the content of all text files based on text recognition technology to obtain respective content information of all text files, and calculate the total number of characters contained in all text files according to the respective content information of all text files, The total number of characters contained in each text file is determined as the amount of information contained in the respective file content of all text files; after that, all text files can be sorted according to the order of The top N information files are selected from the text files, and the top N information files are determined as N target text files.

Step 403: Determine the content information of each of the N target text files.

Step 404: Generate summary information of each of the N target text files according to the content information of each of the N target text files.

For example, the TextRank algorithm can be used to generate the summary information of each of the N target text files. For example, when the TextRank algorithm is used for summary generation, first obtain all the text contained in the text file, and then split the text into a single sentence. Each sentence is represented by a vector, and then the similarity between the sentence vectors is calculated, and the sentence similarity is sorted by size, and finally the sentences with the highest similarity ranking form summary information. It should be noted that the above-mentioned algorithm for generating summary information can be but not limited to the TextRank algorithm.

Step 405: Based on the text-to-picture technology, convert the respective summary information of the N target text files into corresponding pictures.

Step 406: Compress the respective pictures of the N target text files obtained by the conversion to obtain N thumbnail images of the N target text files.

Step 407: Use N thumbnails as cover information of the target folder.

Optionally, based on a preset multi-level thumbnail strategy, the N thumbnails are typeset and combined to generate a composite thumbnail, and the composite thumbnail is determined as the cover information of the target folder.

According to the information file processing method of the embodiment of the present application, all the text files in the text folder can be obtained; then, according to the size of the information contained in the file content, N target text files are selected from all the text files to generate N N thumbnails of the target text file, and use the N thumbnails as cover information of the text folder. Therefore, through artificial intelligence recognition technology, the most representative text files are intelligently recognized from the text folder, and the thumbnails corresponding to these text files are used as the cover of the folder, so that the cover of the folder has the subjectivity. This allows users to quickly learn the content of the text files in the folder by viewing the cover of the folder, which improves efficiency and improves user experience.

This application also provides another information file processing method. This method is suitable for processing the information content recorded in the file to generate the cover information of the file, so that the user can quickly learn the information content in the file by viewing the file cover (such as the icon of the file). The icon of a file in WORD, PDF and other formats can understand the information recorded in the file. Specifically, FIG. 5 is a schematic flowchart of another information file processing method provided by an embodiment of the application.

As shown in Figure 5, the processing method of the information file includes the following steps:

Step 501: Determine a target file, where the target file contains at least one page of information content.

In the embodiment of the present application, the target file may be a file in a format such as WORD, PDF, etc., and at the same time, the file must contain at least one page of information content.

Step 502: Select N pages of information content from at least one page of information content as N target information content according to the amount of information contained in the information content, where N is a positive integer.

In the embodiment of the present application, after the target file is determined, at least one page of information content is separately identified to obtain the amount of information contained in the respective information content of the at least one page of information content. Sort at least one page of information content according to the order of the amount of information contained in the information content, select the top N information content from the at least one page of information content, and determine the top N information content as N target information content.

That is to say, after the target file is determined, the information content of each page of the target file can be identified separately to obtain the amount of information contained in each page of the information content of the target file. After that, sort the information content of all pages according to the order of the information content contained in the information content, and select the top N information content from all the information content of the page number, and arrange the selected information content in the top N The information content of is determined as N target information content.

It should be noted that when the information content of each page in the target file is different, the method of obtaining the amount of information contained in the file content will also be different. For example, when the information content is a picture, image recognition technology can be used to obtain the information content contained in the information content; when the information content is text, text recognition technology can be used to obtain the information content contained in the information content.

Step 503: Generate N thumbnails of N target information content.

In the embodiment of the present application, the order of the N target information contents can be determined according to the amount of information contained in the information content, and the compression size corresponding to the N target information contents may be determined according to the order of the N target information contents. , Based on the compression size corresponding to the N target information contents, compress the N target information contents to generate N thumbnails correspondingly. For example, the sequence of the N target information content can be arranged such that the compressed size of the target information content arranged in the front is larger than the compressed size of the target information content arranged in the back. For example, it is determined that the target information content arranged in the first corresponds to The size of the thumbnails is larger than the size of the thumbnails corresponding to the remaining target information content, and the sizes of the thumbnails corresponding to the remaining target information content are all the same.

Step 504: Use N thumbnails as cover information of the target file.

Optionally, based on a preset multi-level thumbnail strategy, N thumbnails are typeset and combined to generate a composite thumbnail, and the composite thumbnail is determined as the cover information of the target file. It should be noted that the multi-level thumbnail strategy may be preset, and the multi-level thumbnail strategy can be understood as combining multiple thumbnails into a composite thumbnail in a hierarchical manner. For example, the composite thumbnail to be generated can be divided into two parts, such as left and right parts, where the left part occupies a larger proportion than the right part, and the thumbnail with the largest amount of information among the N thumbnails As the left part of the composite thumbnail to be generated, the remaining N-1 thumbnails are arranged in the right part in order of the amount of information contained, so that the composite thumbnail can be composed.

It should be noted that, in an embodiment of the present application, if no information content is recorded in the target file, that is, when there are only blank pages in the target file, the default icon in the file format can be used as the cover of the target file. For example, when the pages in a WORD file are all blank pages, the default icon of WORD can be used as the cover of the file.

In the method for processing an information file in the embodiment of this application, a target file is first determined, where the target file contains at least one page of information content; then, according to the amount of information contained in the information content, N pages of information are selected from at least one page of information content The content is regarded as N target information contents, where N is a positive integer; finally, N thumbnails of the N target information contents are generated; N thumbnails are regarded as the cover information of the target file. Therefore, through artificial intelligence recognition technology, the most representative file information content is intelligently identified from the file, and the thumbnails corresponding to these file information content are used as the file cover, so that the cover of the file has the subjectivity and makes the user You can quickly learn the content of the information file by viewing the file cover, which improves efficiency and improves user experience.
