Embodiment approach

[0233] Further, refer to Figure 8 , as an implementation manner, the step S70 includes:

[0234] Step S71: Obtain the identifier of the sample file, where the identifier of the sample file represents whether the sample file is a junk file.

[0235] Specifically, firstly, a corresponding identifier needs to be configured for each sample file in the sample file library, and the category of each sample file needs to be marked. In this embodiment, the categories of the sample files include: junk files and non-junk files.

[0236] When training the classifier, the identifier of each sample file needs to be obtained, so as to obtain whether the category of each sample file is a junk file.

[0237] Step S72: Extract the feature information of the sample file and the feature information of the parent folder of the sample file.

[0238] After the sample file is obtained, the feature information of the sample file and the feature information of the parent folder of the sample file a...

Abstract

The invention discloses a garbage file recognition device. The device comprises a dictionary module for obtaining a parent folder path of a file to be recognized and judging whether the path is located in a preset garbage dictionary, an extraction module for extracting feature information and parent folder information of the file to be recognized, a probability module for calculating a synthetic probability that the file to be recognized is a garbage file according to the feature information and the parent folder information of the file to be recognized, a pre-allocated classifier and a garbage file storage rule set, and a marking module for marking the file to be recognized as the garbage file if the synthetic probability that the file to be recognized is the garbage file is larger than or equal to a preset threshold value. The invention further discloses a garbage file recognition method. Omission of garbage files is reduced, and the garbage file recognition rate is increased.

Description

technical field [0001] The present invention relates to the technical field of information identification, and in particular, to a device and method for identifying junk files. Background technique [0002] As the use time of the mobile phone increases, more and more files are stored in the mobile phone, which causes the problem of freezing of the mobile phone and seriously affects the user experience of using the mobile phone. Therefore, identifying and deleting files that are useless to users (ie, junk files) has always been the focus of research on mobile phone housekeeper software. [0003] At present, the existing methods for identifying junk files all use methods based on junk dictionaries. This method needs to find out the path information of garbage files generated by various common application software through a large number of tests, and then organize the path information into a garbage path database (garbage dictionary). When cleaning junk files, the criterion f...
