Abstract

PURPOSE: To improve operability and reduce the management cost of a file by automatically grouping and structuring files as a user intends. CONSTITUTION: A file operation content analyzing means 11 analyzes the contents of file operation on the file group, i.e., commands and events of file operation from a computer 2. A file classifying means 12 classifies the files on the basis of the analytic result of the file operation content analyzing means 11. A file structuring information management means 13 stores the file names of the files, classified by the file classifying means 12, in a state wherein they correspond to the classifications of the files, and manages the files. Namely, files retrieved with the same character string are classified into the same group according to the contents of user's file operation such as 'retrieval' and 'open', and files in reference and nonreference relation are classified into the same groups, thereby automatically classifying and structuring individual information, which is hardly systemized with fixed uniform standards, as the user intends when accessing the files.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file management apparatus and method and a computer system for managing files to be stored with file identification information such as file names.

[0002]

2. Description of the Related Art In recent years, computers have been used for the purpose of document creation, CAD, scientific computing, etc., in the direction of sharing documents by networking a plurality of computers or creating a common database. Various methods have been devised for systematically managing files as a group of data in order to efficiently use a vast amount of information. On the other hand, portable information terminals that manage individual information are also developing, and with the development of such terminals for individuals, the amount of information that individual users should manage increases,
There is an increasing demand for managing personal information in accordance with the file management method described above.

As a file management method as described above, 1) a keyword is attached to a file for retrieval and the file is managed by this keyword. 2) Files are classified and the classification names are managed in a hierarchical tree structure. 3) There is a method of managing with link information between files.

[0004]

According to the management methods 1) and 2) described above, a file is simply registered by adding a keyword and a group name to the file at the time of registration. However, after the file has been registered, the memory of the user regarding the hierarchical order of keywords, classification names, and classification names tends to become ambiguous with the passage of time, and the files managed by these methods are the same as at the time of registration. If the keyword or classification name is not remembered, the target file cannot be searched. In addition, the hierarchical classification name is input in the hierarchical order to enable the search of the target file that follows the tree structure, but if the input order of the classification name is different from the hierarchical order, the tree structure cannot be traced It becomes impossible to search the file.

On the other hand, contrary to the management method of 1) and 2), the management method of 3) makes the memory of the initial keyword ambiguous because files having a close relationship are linked by link information. Even if one of the files in the file group that has a link relationship with a keyword close to this can be searched, the target file can be searched by following the link relationship from this file, and the search will not be possible at all. Absent. However, the management method of 3) has a problem that the management cost of the information is increased because the labor of selecting the related files and grouping them and the labor of giving the link information to the grouped files are large.

[0006] Further, since the personal information of the user is not only organized information so that it can be systematized and the personal information is personally registered and used by the user, it is shared by an unspecified number of users. It is preferable to systematize according to individual user's ease of use rather than orderly and fixed systematization such as information to be stored.

The present invention has been made in order to solve such a problem, and it uses the same character string in accordance with the analysis result of the operation content added to the file, that is, the user's intention of file access. The files to be searched or the files that are in a reference / reference relationship are grouped automatically to structure the files so that the target information can be stored for a long time because it matches the user's intention. It is an object of the present invention to provide a file management device and method that can be searched and have good operability, and have low file management costs.

The present invention also provides layered information constructed based on the classification of files according to the user's individual file access intention and layered information of shared files which are shared resources of an unspecified number of users. By managing by associating with each other, the purpose is to provide a computer system that can search shared files with search information that remains in memory for a long time because it matches the user's intentions, has good operability, and has low file management costs. .

[0009]

FIG. 1 is a diagram for explaining the principle of the present invention. The file management apparatus of the first invention and the file management method of the third invention are the contents of file operation from the computer 2 to the file group 3. That is, a file operation content analysis means 11 for analyzing a file operation command or event
And a file classification means 12 for classifying files based on the analysis result of the file operation content analysis means 11, and file names of files classified by the file classification means 12 are stored and managed in a state according to the classification of the files. The file structured information management means 13 is provided.

In the file management device of the second invention, the file classification means 12 classifies the files searched by the same search character string into the same group and the files having the reference / reference relationship to the same group. In addition to the first invention, the present invention further comprises a means for hierarchically classifying the files classified by the search character string based on the reference / reference relationship of the files.

In the file management method of the fourth aspect of the present invention, the character string used for the search well represents the characteristics of the file to the user, and it is considered that the plurality of files searched by this character string are closely related. Therefore, the file classification means 12 classifies files searched by the same search character string into the same group when the file operation is search,
The file structured information management means 13 stores the files searched by the same search character string as the same group using the search character string as a keyword.

According to the file management method of the fifth invention, in the case of a file reference such as a case where a window is opened to reference another file at the time of editing a file in a multi-window system, a reference file and a reference file which have already been opened. Since it is considered that there is a deep relationship with the referenced file called from, the file classifying means 12 determines that the files having the referenced / referenced relationship are the same when the file operation is the reference open of another file. The files are classified into groups, and the file structured information management means 13 links and stores the reference file and the referenced file.

A file management method of the sixth invention is a means for statically analyzing a file based on the appearance frequency of a character string in the file, and a character string having a high appearance frequency in the file based on the analysis result of this means. And a means for storing the specific information of the sorted files in a state according to the classification of the files.

A computer system according to a seventh aspect of the present invention stores the first layered information that is layered by the file management apparatus according to the second aspect of the invention, in accordance with the user's personal intention, and a shared file that is a shared resource of a plurality of computers. The shared file can be managed by the first layered information by providing a means for managing the shared file by associating it with the second layered information that is layered by another standard with an unspecified number of users in mind.

[0015]

According to the file management apparatus and method of the present invention, files searched by the same character string are classified into the same group or referred to according to the contents of the user's file operation such as "search" and "open". By classifying files that are in a referenced relationship into the same group, personal information that is difficult to systemize according to a fixed uniform standard is automatically classified and structured according to the user's intention when accessing the file. Turn into. Therefore, the user can search for the target file with the unique search information that remains in memory for a long time, and the file management cost is low.

Further, the computer system of the present invention can search for a shared file which is a shared resource of an unspecified number of users with the hierarchical information constructed from the classification of files according to the user's individual intention. Therefore, the user can search for the target file with the unique search information that remains in memory for a long time, and the file management cost is low.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing its embodiments. FIG. 2 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, 10 is a memory, and in the read-only area of the memory 10, for example, when the file operation is “character string search” as one of operating systems, “search character string is used as a keyword "Search" subroutine that describes the task of "recording the file name searched for with a character string in the structured table"
102, and when the file operation is a “file reference” such as opening another window to edit another file when editing the file in a multi-window system, “the original file and the newly opened file” are displayed. File is systematically structured by classifying files searched for with the same character string into groups, such as "Open" subroutine 103 that describes the work "registering as a related file in the structured table". A work information database 101 in which work information for activating a subroutine for structuring a subroutine by linking files having a reference / referenced relationship by linking the files is stored.

In the readable / writable area of the memory 10, an operation history table 104 for storing a history of user file operations, and a group of files grouped by each subroutine started from the work information database 101. Structured table 105 for storing activation information
Are provided.

The CPU 20 follows a file operation command including a search character string input from the keyboard 40 in accordance with
While accessing the file group 301 stored in the external storage device 30 and executing the subroutine corresponding to the file operation started from the work information database 101 stored in the memory 10, the operation history table 104, structured The information is written in the table 105, and the reference file and the referenced file referred to by the reference file are displayed on the CRT50 by using graphics such as multi-window.
To be displayed.

FIGS. 3 and 5 are conceptual diagrams of the structured table 105. FIG. 3 is a structured table obtained by grouping files based on a search operation, and FIG. 5 is based on a file reference operation. It is a conceptual diagram of the structured table obtained by grouping the files. When the file operation is a character string search in a file, the "search" subroutine 102 is started and all files searched with the same character string are registered in the "search file name list" with the character string as a "keyword". It At that time, if the same character string has already been converted into a keyword, the file name is additionally registered in the field corresponding to the keyword. Further, when there is a file opened when the search operation is performed, the file name is added to the “search file name list”.

If the file operation is a file reference for opening / closing a file, the "open" subroutine 103 is activated and the referenced file is called "file name".
Register the referenced file in the column of "Link file name". When multiple files are already opened, the name of the first opened file is registered.

In addition to the method of analyzing the file operation contents every operation, a file operation log of the user may be stored in the operation history table 104 and the operation log may be analyzed. FIG. 6 is a conceptual diagram of the operation history table 104, and the "search" subroutine 102 or the "open" subroutine 103 is activated depending on the item content of "operation" in the operation history table 104.

In the figure, the search operation with the "file of Keyword 0" as the target file is performed when the search character string is represented by a regular expression (for example, a regular expression such as a character string including "Akashi" is "Akashi Kaikyo"). "Ariake Ishibashi" is shown as a search target), in this case, each of the character strings actually used for the search (in the above example, "Akashi Kaikyo""AriakeIshibashi") Structured table 10
Register in 5 (see Figure 3).

These operation logs are registered in the operation history table 104 in the order of operation occurrence (from top to bottom in FIG. 6).
It may be deleted when the file is structured. Further, past operation logs whose time and date have passed without being structured may not comply with the user's current intention, so they are deleted. If the file operation is “delete”, the file name of the file to be deleted registered in the structured table 105 is deleted.

Next, one embodiment of the processing of the file management apparatus of the present invention will be described based on the flowchart of FIG. When a file operation occurs, the CPU 20 analyzes the file operation content and obtains work information corresponding to the file operation content (S1). The CPU 20 searches the work information database 101 for whether work information is registered (S2). If the work information is not registered in the work information database 101, the CPU 20 terminates the processing, but if the work information is registered, the corresponding subroutine is activated to update the structured table 105 (S3).

FIG. 4 is a conceptual diagram when the structured table in which the files searched by the same character string shown in FIG. 3 are grouped is expressed as a tree structure. As is clear from the figure, the file is systematically structured by grouping the files with the search character strings as keywords, and the words that consist of the character strings used in the search or words that include this character string are Every keyword is made into a keyword. Therefore, even if the files managed by this management information are searched in the order of "keyword 0" and "keyword 1", or conversely, in the order of "keyword 1" and "keyword 0",
File candidates that always include the target file are searched.
When represented by a tree structure, it can be said that the files (for example, the file B and the file D) that are grouped in a deeper hierarchy are deeper than the files in the upper layer.

As another method of systematically structuring a file, a method of statically analyzing the file can be considered in addition to the analysis of the file operation. As a static analysis, for example, the frequency of occurrence of each word in each file is counted,
File comrades whose words have the same highest frequency of occurrence are grouped by using these words as keywords. At this time, when the number of files is large, the number of ranks from the top where the words match may be reduced, and when the number of files is small, the rank may be increased.

The file static analysis does not necessarily have to be performed by the file management apparatus itself, but the static analysis may be performed by another computer having a high processing speed and the analysis result data may be used.

Further, a computer system using the file management apparatus of the present invention is provided with a thesaurus, etc. as a database, a synonym of a search character string is detected at the time of file search, and a file is searched with this synonym other than the search character string. By doing so, the hit rate of file search is increased.

Further, the structured information of the personal information structured by the file management device and management method of the present invention and the structured tree structure in a network system using a common file as a shared resource of a plurality of computers. If the information is managed in association with it, the shared file can be managed by the personalized structured information.

[0031]

As described above, the file management apparatus and method according to the present invention, in accordance with the analysis result of operation contents added to a file, that is, the user's intention of file access,
Files that are searched with the same character string, or files that are in a reference / reference relationship are grouped automatically to structure the files, so that the search information can be stored in memory for a long time because it matches the user's intention. It has an excellent effect that the target file can be searched and the operability is good, and the file management cost is low.

In the computer system of the present invention, the hierarchy information constructed based on the classification of files according to the user's individual file access intention and the hierarchy of the shared file which is a shared resource of an unspecified number of users. Since it is managed by associating it with the computerized information, it is possible to search the shared file with the search information that remains in memory for a long time because it is in line with the user's intention, and the operability is excellent and the file management cost is low. Play.
