Abstract

The invention provides a file classification management system and method used in operating systems for managing the files by categories. Each of the physically stored files is mapped into one or more logical categories based on the contents of the file. And a desktop files resource manager presents the files by categories organized in a tree structure such that the user can directly find desired files via categories by using the present invention. The invention significantly improves the function of the file system and makes the file management interface more friendly.

Claims

1. A classification management system for use in operating systems, said classification management system comprising:

a file classification management system that maps physically stored files into one or more logical categories based on the contents of said files.

2. The classification management system according to claim 1, characterized in that said file classification management system includes:

a file classification device for classifying a file based on its contents;

a classifier for storing classification standards depending on which to classify a file; and

a file classification mapping database for storing classified results.

3. The classification management system according to claim 2, characterized in that said file classification device includes:

a file information extractor for extracting the file type and content information from the file to be classified;

a file information analysis unit for analyzing the extracted information;

a file classification unit for providing the analyzed results to the classifier to find one or more optimal matches, classifying the file into one or more categories corresponding to the optimal matches, and storing the classified results into the file classification mapping database.

4. The classification management system according to claim 1, characterized in that said system further includes:

a desktop files resource manager of operating systems, which displays the categories and the file information of all files belonging to each of the categories organized in a tree structure.

5. The classification management system according to claim 4, characterized in that said file information includes the file name.

6. The classification management system according to claim 5, characterized in that said file information further includes at least one of the file type, file size and last updated time of the file.

7. The classification management system according to claim 1, characterized in that said system includes a selection unit, wherein a file will be classified manually when manual classification is selected, and the file will be classified automatically when automatic classification is selected.

8. The classification management system according to claim 7, characterized in that said classifier is a statistic classifier which uses statistic classification algorithm.

9. The classification management system according to claim 7, characterized in that said classifier is a rule-based classifier which uses rule decision.

10. The classification management system according to claim 9, characterized in that said rule is manually set.

11. The classification management system according to claim 9, characterized in that said rule is set through machine learning.

12. The classification management system according to claim 1, characterized in that said system provides for said category to include sub-categories.
