Abstract

A file management apparatus which makes it possible to cache a file registered in a file server from an initial stage of registration thereof. When a file is newly registered in the file server, the file server extracts the feature elements of the file, and searches for an registered file having a high degree of similarity to the file being registered in response to the current registration request. The search is performed based on the feature elements and an access log. Then, the file server searches for a domain from which access has been made to the file a not smaller number of times than a predetermined number of times, and copies and registers the newly registered file also in a cache server of the domain.

Claims

1. A file management apparatus that manages files shared by a plurality of client terminals, comprising:

a recording unit configured to record access situations in which access is made to the files registered in the file management apparatus from the client terminals;

a search unit configured to search said recording unit for a file having a not smaller degree of similarity to a file newly registered in the file management apparatus than a predetermined threshold value; and

a distribution unit configured to distribute the newly registered file to any of the client terminals from which access has been made to the file found by the search a not smaller number of times than a predetermined number of times.

2. The file management apparatus according to claim 1, wherein said recording unit records a history of reading processes performed on the files registered in the file management apparatus by the client terminals, as the access situations.

3. The file management apparatus according to claim 2, wherein the history of the reading processes includes a history of reading processes executed on the files registered in the file management apparatus in response to print requests from the client terminals.

4. The file management apparatus according to claim 1, wherein said recording unit records feature information extracted from each registered file, in association therewith;

the file management apparatus further comprising an extraction unit configured to extract feature information on the file newly registered, and

wherein said search unit searches said recording unit for the file having a not smaller degree of similarity to the file newly registered, using the feature information extracted by said extraction unit and the feature information recorded in said recording unit.

5. The file management apparatus according to claim 4, wherein the feature information on the file comprises keywords included in the file.

6. The file management apparatus according to claim 4, wherein the feature information on the files comprises concept indexes.

7. The file management apparatus according to claim 4, wherein the feature information on the file comprises features of images included in the files.

8. The file management apparatus according to claim 4, wherein the feature elements of the files are metadata representative of contents of the files.

9. The file management apparatus according to claim 1, wherein said distribution unit distributes a duplicate of the file registered in the file management apparatus to a cache server for registering duplicates of ones of the files registered in the file management apparatus.

10. A file management apparatus according to claim 1, wherein said distribution unit further distributes the registered file found by the search by said search unit to an image forming apparatus by which the file is printed in a not lower frequency than a predetermined threshold value.

11. A file management method for a file management apparatus, for managing files shared by a plurality of client terminals, comprising:

recording access situations in which access is made to the files registered in the file management apparatus from the client terminals;

searching for a file having a not smaller degree of similarity to a file newly registered in the file management apparatus than a predetermined threshold value; and

distributing the newly registered file to any of the client terminals from which access has been made to the file found by the search a not smaller number of times than a predetermined number of times.

12. A computer-readable storage medium storing a program for causing a computer to execute a file management method for a file management apparatus, for managing files shared by a plurality of client terminals,

wherein the method comprises:

recording access situations in which access is made to the files registered in the file management apparatus from the client terminals;

searching for a file having a not smaller degree of similarity to a file newly registered in the file management apparatus than a predetermined threshold value; and

distributing the newly registered file to any of the client terminals from which access has been made to the file found by the search a not smaller number of times than a predetermined number of times.
