IT wave makes the data of electronization roll up, and the fast development of big capacity hard disk technology is then in technology with financially provide the possibility of storing heap file in computing machine for the user.When the file of storing in the hard disc of computer reaches some, how effectively to manage, search and use these files just to become an important problem.Particularly when the user need carry out software development at file management, it is more outstanding that this problem just seems.In other words, compare with capacity problem, it is more and more important that efficiency is just seeming.
The user can use file management system self-built in the operating system at present, at present pandemic Windows operating system, generally the file management system of Shi Yonging is FAT32 and NTFS, and NTFS has become the main flow file management system of Windows operating system at present.Application software needs to use these two kinds of file management systems to operate when using file.Because the closure of these two kinds of file system, make us can't further obtain its operational detail, and with regard to its operation performance, when carrying out the files in batches processing, batch as a certain type file uses, has the retrieval of some same characteristic features file etc., has following deficiency:
1, comes management document according to filename.Filename is the basis of NTFS as the file most important characteristic, and the demand file name has uniqueness to a certain extent, when showing the user, also with filename as topmost displaying feature.And in actual use, the user gives identical filename for the different files under the different paths sometimes, when these files of user search, is difficult to be distinguished.
2, file is adopted accurate management Strategy.NTFS can accurately manage it according to the various features of file, as file name, and type, key word, date created is revised the date, path etc.When a plurality of files during at same theme, if the feature of these files in NTFS do not have the correlativity of dominance, as: the human resources file of checking a certain employee, may comprise the employee information file, labour contract file etc., but state's laws rules file sometimes, the relevant manpower policy document of company etc. also can appear among the result.NTFS can't judge user's needs and provide satisfactory result that the user must manually realize or realize automatically by database software automatically.
3, adopt the strategy that uses as required fully.That is: when the user need use the file with certain feature, Windows just can search by the NTFS file management system, search finish after, just can need operate according to the user.Operate at file with regard to making like this, particularly the quantity of documents that will operate more for a long time, execution efficient is on the low side.
Summary of the invention
The purpose of this invention is to provide a kind of file management method and management system of using fuzzy matrix, automatically file is carried out traversal search, set up fuzzy set, set up file management according to the feature that it characterized and the value of degree of membership.When the user operated at the file with a certain feature, the presents management system can find associated documents fast according to the fuzzy set of having set up before this, and according to its degree of membership ordering, used for the user.
The invention provides a kind of file management method, comprising:
1) file in the hard disk is carried out traversal search,, obtain its all feature in NTFS at each file;
2) according to the feature of the file that obtains, the degree of membership fuzzy matrix of spanned file, degree of membership is represented the degree of correlation of file and feature;
3) according to the file characteristic of user's appointment, call the degree of membership fuzzy matrix, list the file that possesses this feature.When the user need operate at the file with a certain feature, method of the present invention can be listed the corresponding file that possesses this feature according to each degree of membership of the file that has this feature in the fuzzy matrix;
Described file management method utilizes the idling-resource of operating system to carry out automatically.
The file of described traversal search is the user file in the hard disk.System file is not searched for.The identification of user file can utilize the existing techniques in realizing of terminal operating system.
The generation method of described degree of membership fuzzy matrix is:
A, the rank associated with the file according to feature, i.e. the priority of feature generates the feature sparse matrix of single file, and the non-zero entry of matrix is represented the feature of this document;
B, on the basis of feature priority, obtain the degree of membership value of a file and a feature, promptly obtain the degree of correlation value of file and feature.The degree of membership value can manually be set by the user, and the binary contrast ranking method that also can adopt present widespread use is by calculating automatic setting.
C, the degree of membership that will comprise the All Files of same feature generate fuzzy set;
D, the fuzzy set of all features is combined to form the degree of membership fuzzy matrix, the degree of membership fuzzy matrix is the total characteristic sparse matrix, and a non-zero entry in the matrix is represented a kind of feature.The total characteristic sparse matrix no longer is at the sparse matrix of some specific files, but at the feature sparse matrix of all user files, all corresponding fuzzy set of non-zero entry characteristic of correspondence.Each fuzzy set all regarded as directly generate a element in the sparse matrix sparse matrix and get final product, the simple application of mathematical concept just here, the total characteristic sparse matrix be generated as prior art.
The generation of described fuzzy set is to locate the file that all comprise same feature by single feature sparse matrix.The feature sparse matrix of file is used for the feature that markup document had, and by sparse matrix, can locate the All Files that comprises a certain feature fast.Thereby the degree of membership of quick spanned file; Significantly reduce computing time.
The ordering of element is according to the ordering of degree of membership size in the described fuzzy set.Promptly according to the size of degree of membership value to the adjustment of sorting of element in the fuzzy set.
The described method of calling the fuzzy matrix files listed comprises:
Call the degree of membership fuzzy matrix, according to the nonzero element in user's specific characteristic extraction fuzzy matrix;

Fig. 3 is a process flow diagram of handling this document among Fig. 2, when user file is new untreated user file, all features of extraction document and generate the Features Management table of this document then, simultaneously according to this Features Management table, generate single file characteristic sparse matrix, the non-zero entry of matrix represent file feature.If this user file is the user file of handling, then find existing file characteristic admin table of this user file and corresponding file feature sparse matrix; Read each feature in the file characteristic admin table then, each feature is handled.
Fig. 4 has then shown flow process that feature is handled in the file characteristic admin table.Judge at first whether this feature was handled, if handled then backspace file processing; If do not handle to judge then whether this feature is new feature, if be not new feature, then directly read the degree of membership value of this feature, if this is characterized as the degree of membership value that new feature then generates this feature, this value is generated by binary contrast ranking method; The Features Management table of final updating file.
Can obtain the degree of membership value of a feature comprising in the file through above-mentioned processing.
Table 1 is the file characteristic admin table example of a certain file.The file characteristic admin table comprises the title or the description of feature, represents with capitalization A, B, C in example, has represented the feature of the required expression of user.Priority has been represented the relevant rank of file with feature, and the feature that priority is high shows that the significance level of the relative this document of this feature is also high, and the feature that priority is high will preferentially be offered the user and use.Degree of membership is represented the concrete degree of correlation of this document and each feature, and under the identical situation of priority, the file that degree of membership is high will preferentially be offered the user and use.
Table 1 file characteristic admin table
| Feature | A | B | C | D |
| Priority | 1 | 2 | 3 | 4 |
| Degree of membership | 0.75 | 0.88 | 0.63 | 0.44 |
(3) generate the degree of membership fuzzy set
Through above-mentioned file processing, obtain each file relatively after the degree of membership of each feature, the degree of membership that will comprise the All Files of same feature generates fuzzy set; As shown in table 2, the file that comprises the human resources feature has " employee's performance information ", " evaluation of employee evaluation ", " employee's essential information ", " employee post regulation ", " company's manpower system ".
Table 2 human resources file admin table
| File | Employee's performance information | Evaluation of employee is estimated | Employee's essential information | Employee post regulation | Company's manpower system |
| Priority | 1 | 1 | 3 | 2 | 4 |
| Degree of membership | 0.78 | 0.84 | 0.60 | 0.65 | 0.43 |
(4) fuzzy set with all features is combined to form the degree of membership fuzzy matrix, and the degree of membership fuzzy matrix is the total characteristic sparse matrix, a non-zero entry correspondence in the matrix fuzzy set.The preferred diagonal line sparse matrix of this matrix.Element in the fuzzy set is by degree of membership height series arrangement.
The 3rd, the user can carry out file operation behind the acquisition fuzzy matrix.
File characteristic according to user's appointment calls fuzzy matrix, and according to the fuzzy set of this feature correspondence, drop goes out to blur concentrates the degree of membership corresponding file, and exports from high to low by degree of membership.As shown in Figure 1, the user can operate file by the fuzzy data Processing Interface in the file polling device by the application program of oneself developing, that is to say, the user can import feature that the user need retrieve and required priority lower limit and degree of membership lower limit in the Fuzzy Processing interface, find out qualified file.
During such as inquiry " human resources " this feature, suppose that it is 3 that the user sets the priority lower limit, the degree of membership lower limit is 0.70.If the relation of the two is set at " or ", then Search Results is higher than 3 grades with display priority, and degree of membership is higher than 0.70 All Files.Then " employee's performance information ", " evaluation of employee evaluation ", " employee post regulation " these three files all become Search Results; " employee's essential information ", though priority meets the requirements, degree of membership is lower than 0.70, can not become Search Results; " company's manpower system " can not become Search Results equally.If the relation of the two is set at " with ", then only " employee's performance information ", " evaluation of employee evaluation " this two each and every one file become Search Results, and " employee post regulation " is because degree of membership is lower than 0.70, not as Search Results.Search Results is listed to the user with the form of two dimension according to the height order of priority and degree of membership.
