Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Example one
In order to solve the technical problems in the prior art, the embodiment of the invention provides a method for clearing data, which has low data clearing efficiency and high error rate.
Fig. 1 is a flowchart of an embodiment of a data cleansing method of the present invention, and as shown in fig. 1, the data cleansing method of the present embodiment may specifically include the following steps:
100. if the storage capacity of the storage space of the cleaning object is monitored to be larger than or equal to a preset threshold value, extracting the data characteristics of the stored data in the storage space;
in a specific implementation process, the storage amount of the storage space of the cleaning object can be monitored in real time, wherein the cleaning object comprises the terminal itself and at least one application program in the terminal. The storage amount of the storage space of the cleaning object comprises the data amount of the stored data, namely the data amount existing in the storage space of the cleaning object when the cleaning object does not need to download new data. Or the storage amount of the storage space of the cleaning object comprises the sum of the data amount of the stored data and the data amount of the data to be stored. That is, when the cleaning object needs to download new data, the sum of the data amount already existing in the storage space of the cleaning object and the data amount of the data to be stored.
In this embodiment, after the storage amount of the storage space of the cleaning object is monitored, the storage amount of the storage space of the cleaning object may be compared with a preset threshold, and if the comparison result indicates that the storage amount of the storage space of the cleaning object is monitored to be greater than or equal to the preset threshold, it indicates that the data in the storage space of the cleaning object is more, and the cleaning object may be stuck, crashed, stopped, or the like.
In this embodiment, the preset threshold may be set by the user according to the actual needs of the user. The data characteristics of the stored data in the storage space comprise at least one of data use frequency, data storage time and data type; the data type includes at least one of a video class, a game class, a business class, a social class, a transaction class, a non-copyright class, a collection class, and a tag class.
101. Determining stored data meeting the automatic cleaning authority in the stored data according to the data characteristics of the stored data;
after the data characteristics of the stored data in the storage space are extracted, the stored data meeting the automatic cleaning authority in the stored data can be further determined according to the data characteristics of the stored data. For example, the data characteristics of the stored data may be input into a data recognition model constructed by an artificial intelligence technique for data analysis, so as to obtain the stored data satisfying the automatic cleaning authority among the stored data and the stored data satisfying the manual cleaning authority among the stored data.
Specifically, after a certain amount of historical behavior data of the cleaning object used by the user is used as training data to train, a data recognition model is constructed, so that the data in the cleaning object is classified, and the stored data meeting the automatic cleaning authority in the stored data and the stored data meeting the manual cleaning authority in the stored data are obtained. For example, the stored data satisfying the manual cleaning authority in the stored data is preferably data of a transaction type, a non-copyright type, a collection type, a mark type, or the like, and may also be data whose use frequency is greater than a preset frequency. And other data can be classified as stored data satisfying the automatic cleaning authority, such as data with the use frequency less than the preset frequency, data without a mark, data for collection, and the like.
Such as identifying screenshots of money to and from to avoid automatic deletion, identifying pictures and content that are marked by the user as "favorite" or "favorite" types to avoid automatic deletion. Whether the downloaded music or other resources are in a non-copyright state in the current application or the Internet or not is detected, and the serious loss caused by deletion is avoided. Because the video and audio resources on the network are frequently changed due to copyright. Downloading is done in a copyrighted state, but over time, even if resources are off-shelf on the network because of copyright issues, there is no way to get downloads from elsewhere on this piece of software. At this time, it is very important to discriminate whether the downloaded resources in the mobile phone are 'solitary', and the data can be classified as stored data meeting the manual cleaning authority. And in other cases, may be categorized as stored data that satisfies the automatic cleaning authority.
102. And clearing the stored data meeting the automatic clearing authority based on a preset automatic clearing strategy, and stopping the automatic clearing operation until an automatic clearing stopping condition is met.
In a specific implementation process, according to the data characteristics of each storage data in the storage data meeting the automatic cleaning authority, determining the automatic cleaning grade of each storage data in the storage data meeting the automatic cleaning authority, and cleaning the storage data meeting the automatic cleaning authority according to the sequence from the low grade to the high grade of the automatic cleaning grade until the automatic cleaning stop condition is met, and stopping the automatic cleaning operation. The automatic clearing stop condition in this embodiment may include that the storage amount of the storage space is smaller than a preset threshold, or that all the storage data meeting the automatic clearing authority is cleared.
For example, the automatic cleaning level of each of the stored data satisfying the automatic cleaning authority may be set according to the following rule: less common software cache > frequency of use common software cache > common software cache. The embodiment is not limited to the example listed in the above 3, and the user may perform a custom setting according to actual needs. For example, 4 levels can be taken as an example, the first level automatically deletes the application cache which is not commonly used and the downloaded installation package, the second level automatically deletes the application cache which is mainly video, music and browse, the third level automatically deletes the picture and video cache in the chat software, and the fourth level automatically deletes the picture with high repetition degree in the photo album and uninstalls the application which is never opened for more than 3 months.
In the data cleaning method of this embodiment, if it is monitored that the storage amount of the storage space of the cleaning object is greater than or equal to a preset threshold, data features of stored data in the storage space are extracted; after the stored data meeting the automatic cleaning authority in the stored data are determined according to the data characteristics of the stored data, the stored data meeting the automatic cleaning authority are cleaned based on a preset automatic cleaning strategy until the automatic cleaning stopping condition is met, and then the automatic cleaning operation is stopped, so that manual cleaning is avoided, the type of the data can be accurately distinguished, and data are prevented from being deleted by mistake. By adopting the technical scheme of the invention, the data cleaning efficiency and the data cleaning accuracy can be improved, the safety and the stability of the data can be improved, and the hesitation and the difficulty in selecting the data when the user manages and deletes the data can be reduced.
Fig. 2 is a flowchart of another embodiment of the data cleansing method of the present invention, and the data cleansing method of the present embodiment further describes the technical solution of the present invention in more detail based on the above embodiment. As shown in fig. 2, the data cleaning method of this embodiment may specifically include the following steps:
200. if the storage capacity of the storage space of the cleaning object is monitored to be larger than or equal to a preset threshold value, extracting the data characteristics of the stored data in the storage space; the storage amount of the storage space comprises the data amount of the stored data, or the sum of the data amount of the stored data and the data amount of the data to be stored;
201. determining stored data meeting the automatic cleaning authority in the stored data according to the data characteristics of the stored data;
202. based on a preset automatic clearing strategy, clearing the stored data meeting the automatic clearing authority;
203. if the stored data meeting the automatic cleaning authority are completely cleaned and the storage amount of the storage space is greater than or equal to a preset threshold value, outputting the stored data meeting the manual cleaning authority in the stored data;
specifically, the manual cleaning level of each storage data in the storage data meeting the manual cleaning authority can be determined according to the data characteristics of each storage data in the storage data meeting the manual cleaning authority; and outputting each storage data in the storage data meeting the manual cleaning authority according to the sequence from the low level to the high level of the manual cleaning level.
The setting method of the manual cleaning level of each storage data in the storage data meeting the manual cleaning authority is also determined according to the use habits and relevant settings of the user, and is specifically similar to the manner of the automatic cleaning level of each storage data in the storage data meeting the automatic cleaning authority, and is not described herein again.
204. Receiving a cleaning request aiming at least one target storage data in the storage data meeting the manual cleaning authority;
205. and cleaning at least one target storage data.
In this embodiment, after the automatic cleaning, if the storage amount of the storage space of the cleaning object is still greater than or equal to the preset threshold, it may be output in a targeted manner which data is preferentially and manually deleted by the user to achieve the fastest data management.
Further, in the above embodiment, before step 204, a selection instruction for at least one to-be-cleaned storage data in the storage data satisfying the manual cleaning authority may also be received; and outputting the data characteristics of at least one piece of to-be-cleaned storage data, so that the controller can more accurately select at least one piece of target storage data according to the data characteristics of the at least one piece of to-be-cleaned storage data, and the data is prevented from being deleted by mistake.
The following describes the technical solution of the present invention by taking a mobile phone as a cleaning object and taking an example that the mobile phone needs to download new data, and the specific implementation process is as follows:
(1) after the operator a sets the preset threshold function and the deletion permission, if the storage space of the mobile phone reaches the preset threshold, the system will automatically delete the least important cache and files for the user, the system will not ask the user, and the user can use the mobile phone with confidence.
(2) At present, only 3G are left in the mobile phone, a new movie on the network today needs 5G memories, the operator a increases the original preset threshold to 6G, the data cleaning device starts to detect, and the data is automatically cleaned according to the priority level: the method comprises the steps that a first level automatically deletes the application cache which is not commonly used and an installation package which is downloaded, a second level starts to delete the application cache which is mainly video, music and browsing, a third level deletes pictures and video cache in chat software, a fourth level deletes pictures with high repeatability in an album and uninstalls applications which are never opened for more than 3 months, when the pictures with high repeatability such as chat screenshots are deleted, a system can identify economic and incoming transaction screenshots related to account transfer and the like and avoid deletion, and the application which is not commonly used is approved by an operator A before deletion.
It should be noted that the operator a may also directly execute the operation of automatically cleaning the data without modifying the preset threshold. And if the storage space of the mobile phone reaches a preset threshold value, new data cannot be downloaded.
(3) If the operation is not yet required by the operator A after the operation is completed, the operator A is prompted to delete the operation manually, the system can obtain that the user type is video, game, official, social and the like according to the use frequency of the application, and then the user is pertinently advised to preferentially delete which applications and caches so as to manage the file at the highest speed.
It should be noted that the method of the embodiment of the present invention may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In the case of such a distributed scenario, one device of the multiple devices may only perform one or more steps of the method according to the embodiment of the present invention, and the multiple devices interact with each other to complete the method.
