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, and the identifier of the sample file represents whether the sample file is a junk file.

[0235] Specifically, firstly, it is necessary to configure a corresponding identification for each sample file in the sample file library, and mark the category of each sample file. In this embodiment, the categories of sample files include: junk files and non-junk files.

[0236] When training the classifier, it is necessary to obtain the identification of each sample file, so as to obtain whether the category of each sample file is a junk file.

[0237] Step S72, extracting feature information of the sample file and feature information of the parent folder of the sample file.

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

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, in particular to a garbage file identification device and method. Background technique [0002] As the usage time of the mobile phone increases, there will be more and more files in the mobile phone, which will cause the freeze problem of the mobile phone and seriously affect the user experience of the user using the mobile phone. Therefore, identifying and deleting files that are useless to users (i.e., junk files) has always been a key issue in the research of mobile phone housekeeping software. [0003] At present, the existing methods for identifying junk files all adopt methods based on garbage dictionaries. This method needs to find the path information of junk files generated by various commonly used application software through a large number of tests, and then organize these path information into a junk path database (garbage dictionary). When cleaning junk f...
