[0001]
BACKGROUND OF THE INVENTION
  According to the present invention, when storing (or registering) a file such as a document, attribute information indicating attributes such as the storage destination and classification of the file is made into a database together with management identification information (hereinafter referred to as “management ID”). Electronic filing method and device for searching document filesIn placeRelated.
[0002]
[Prior art]
When storing a file such as a document in an external storage medium or the like, a management database is created by attribute information indicating the storage destination or classification of the file such as a disk name or volume name, path name, or directory, and a management ID corresponding to the attribute information. 2. Description of the Related Art Conventionally, an electronic filing apparatus that is created and stores this management database in a memory such as a hard disk is known. In this apparatus, keywords in the file are automatically cut out, a keyword database in which the cut out keywords are associated with the file management ID is created separately, and the management ID of a file including a keyword can be easily created using this keyword database. I try to understand. When searching for a file, the management ID is obtained from the keyword database using the keyword as a clue, and attribute information is acquired from the management database based on the management ID. Thereby, a desired file can be searched.
[0003]
[Problems to be solved by the invention]
However, in the conventional electronic filing apparatus, when the stored file is deleted, added, copied, etc., the contents of the keyword database as well as the management database are directly changed each time. Therefore, when the data amount of the keyword database is increased, there is a problem that the response of the file revision / removal processing is remarkably deteriorated. For example, when deleting a certain file (with management ID “100”), it is necessary to delete all management IDs “100” registered in the keyword database. One management ID usually corresponds to many keywords, and when the number of registrations is large, processing takes time. The same applies to file addition and copying.
[0004]
  The present invention has been made in order to solve the above-described problems of the prior art, and an object of the present invention is to provide electronic filing capable of improving the response of processing such as file revision / decommissioning while ensuring the accuracy of the file search processing.

[0027]
The electronic filing apparatus is connected to a storage unit 6 (first and second storage means) of an external computer via a control bus 16, a data bus 17 and an address bus 18.
[0028]
The CPU 1 executes various calculations for the electronic filing process, logic judgment, and the like, and controls the operation of the components of the electronic filing apparatus. At that time, the CPU 1 transmits a control bus signal to each component to be controlled via the control bus 16. Further, the CPU 1 transmits a signal for designating the corresponding address of each component in the memory of the CPU 1 to each component via the address bus 18. The data bus 17 is used for transmission / reception of data between components.
[0029]
The ROM 2 is a read-only fixed memory, and stores a control program to be executed by the CPU 1. The RAM 3 is a memory that can be randomly accessed. The single kanji dictionary unit 4 is used for designating radicals, number of strokes, and single kanji when inputting kanji. The kana-kanji dictionary unit 5 is used when performing kana-kanji conversion.
[0030]
The external storage device 7 is configured to be able to insert a floppy disk, and stores a file such as document data on the floppy disk. The keyboard 9 is used for the user to input various instructions. The keyboard buffer 8 is a memory for temporarily storing scan codes transmitted from the keyboard 9. The document buffer 10 temporarily stores text data in the file registration process. The database buffer 11 temporarily stores various databases in the file registration process, and stores the management ID and attribute information acquired in the file search process.
[0031]
The cursor register 12 holds the address of the cursor on the display screen of the CRT 15, and the contents are read and written by the CPU 1. The video buffer 13 stores pixel data for one screen of the CRT 15 obtained by bit development of the character code in the document buffer 10. The D / A converter 14 converts the digital code pixel data stored in the video buffer 13 into analog data. The CRT 15 visually displays the pixel data converted into the analog data. Further, the CRT 15 inputs the cursor address from the cursor register 12 and displays the cursor at a position corresponding thereto.
[0032]
The storage unit 6 is provided in an external computer that can communicate with the electronic filing device, and includes a hard disk or the like. The storage unit 6 stores various databases, which will be described later, in a database format, and transmits the databases to the RAM 3 as necessary. The storage unit 6 may be connected to a plurality of devices having the same configuration as the electronic filing device. In this case, the storage unit 6 is a so-called server and the electronic filing device is a so-called client. Become.
[0033]
In such a configuration, at the time of filing processing such as file registration, deletion, and copying, an interrupt signal is transmitted from the keyboard buffer 8 to the CPU 1 according to an instruction from the keyboard 9, and the CPU 1 reads various control signals in the ROM 2, Various controls are executed according to the control signal.
[0034]
FIG. 2 is a conceptual diagram showing a database stored in the storage unit 6 in the electronic filing device according to the first embodiment.
[0035]
The database used in the first embodiment includes a keyword database 30 (first database) shown in FIG. 5A, a management database 31 (second database) shown in FIG. ) And unnecessary number management ID data 33 shown in FIG.
[0036]
The keyword database 30 is a database of keywords automatically extracted from a file by a known method, and is an index based on a list of keywords and management IDs. The management ID is information for specifying the registered file, and is assigned to each file at the time of file registration. In the keyword database 30, as shown in FIG. 5A, the same record is recorded so that all the management IDs (Nos. 7, 100, 305, 1942, etc.) of the files including each keyword (“Canon”, etc.) correspond. It is remembered. The keyword database 30 is created when a file is registered, and is used to obtain a management ID from the keyword when searching for a file. The management ID is deleted by a keyword database cleaning process described later.
[0037]
The management database 31 is a database of attribute information such as a document ID, a file ID, and a file name with respect to the management ID. In the management database 31, for example, the management ID “2” corresponds to the same record such that the document ID is “88”, the file ID is “1”, and the like. The management database 31 is created when a file is registered, and is used for obtaining attribute information from the management ID when searching for a file. Each record in the management database 31 is deleted by a file deletion process described later.
[0038]
In the unnecessary management ID data 32, an unnecessary management ID designated in a file deletion process described later is registered (details will be described later), and the unnecessary management ID data 32 is stored in the storage unit 6.
[0039]
In the missing number management ID data 33, a management ID deleted in a keyword database cleaning process described later is registered (details will be described later), and the missing number management ID data 33 is stored in the storage unit 6.
[0040]
FIG. 3 is a flowchart of file deletion processing by the electronic filing device according to the first embodiment. This process is executed by the CPU 1.
[0041]
First, the document ID and file ID of an unnecessary file to be deleted are designated by the keyboard 9 (step S301), and it is determined whether or not the designated document ID and file ID are included in the management database 31 (step S302). . As a result of the determination, if the specified document ID and file ID are not included in the management database 31, the present process is immediately terminated. On the other hand, if the specified document ID and file ID are included in the management database 31, A management ID corresponding to the designated document ID and file ID is acquired from the management database 31 (step S303), and a record (management ID and attribute information) corresponding to the acquired management ID is deleted from the management database 31 ( In step S304, the acquired management ID is registered in the unnecessary management ID data 32 (step S305), and this process ends.
[0042]
For example, when the processing shown in FIG. 2 is performed with the document ID “90” and the file ID “2” specified as the initial state, the management ID “3” is retrieved from the management database 31 shown in FIG. When the record “100” is deleted, the management database 31 is in a state as shown in FIG. As for the unnecessary management ID data 32, the management ID “100” that has not been registered in FIG. 2C is newly registered as shown in FIG. 4C. Since the keyword database 30 is not changed at all, there is an advantage that the load of this process can be very small. Further, the missing number management ID data 33 is not changed.
[0043]
According to the processing of FIG. 3, a record composed of an unnecessary file management ID and attribute information is deleted from the management database 31, and the management ID of the file is registered in the unnecessary management ID data 32.
[0044]
FIG. 5 is a flowchart of file search processing by the electronic filing device according to the first embodiment. This process is executed by the CPU 1.
[0045]
First, a keyword is designated on the keyboard 9 (step S501), and it is determined whether or not the designated keyword is registered in the keyword database 30 (step S502). As a result of the determination, if the specified keyword is not registered in the keyword database 30, this processing is immediately terminated. On the other hand, if the specified keyword is registered in the keyword database 30, the management ID corresponding to the specified keyword Is acquired from the keyword database 30 (step S503), and the document ID, file ID, and file name corresponding to the acquired management ID are acquired from the management database 31 by the attribute information acquisition process of FIG. 6 described later (step S504). ), This process is terminated.
[0046]
FIG. 6 is a flowchart of the attribute information acquisition process executed in step S504 of FIG. 5 described above.
[0047]
First, it is determined whether or not the management ID acquired in step S503 in FIG. 5 is registered in the management database 31 (step S601). As a result of the determination, the acquired management ID is registered in the management database 31. If not, the process immediately proceeds to step S603. As a result, even if the management ID of the unnecessary file remains in the keyword database 30, if it is deleted from the management database 31, the attribute information of the unnecessary file is acquired as the search result. It can be avoided.
[0048]
On the other hand, if the acquired management ID is registered in the management database 31 as a result of the determination in step S601, the attribute information (document ID, file ID, and file name) corresponding to the acquired management ID is acquired. At the same time, these are stored in the database buffer 11 (step S602), and the process proceeds to step S603.
[0049]
In step S603, it is determined whether or not the process has been completed for all of the acquired management IDs. If the process has not been completed for all of the acquired management IDs, the process returns to step S601, while all of the acquired management IDs are determined. When the process is finished, this process is finished.
[0050]
According to the processing of FIGS. 5 and 6, when the management ID of the file including the specified keyword is registered in the management database 31, the attribute information of the file is acquired.
[0051]
FIG. 7 is a flowchart of the keyword database cleaning process by the electronic filing device according to the first embodiment. This processing is executed by the CPU 1 every predetermined time (for example, at the time of starting up the system, at the time of termination, or at any instruction by the user).
[0052]
First, it is determined whether or not any management ID is registered in the unnecessary management ID data 32 (step S701). If no management ID is registered, this process is immediately terminated, while the unnecessary management ID data 32 is updated. If any management ID is registered, the registered management ID is deleted from the unnecessary management ID data 32 (step S702), and the same management ID as the deleted management ID is added to the head of the keyword database 30. All the last index records are deleted from the index record (step S703), the management ID is registered in the missing management ID data 33 (step S704), and the process returns to step S701. The management ID registered in the missing management ID data 33 can be reused later.
[0053]
For example, when this process is executed with the state shown in FIG. 4 as an initial state, the state shown in FIG. 8 is obtained. That is, the management ID “100” registered in the unnecessary management ID data 32 is deleted from the unnecessary management ID data 32 and is also deleted sequentially from the keyword database 30. When the management ID “100” is deleted from the unnecessary management ID data 32, the management ID is not registered (FIG. 8C), and the keyword database 30 is in the state shown in FIG. Further, the missing management ID data 33 is changed from an unregistered state (FIG. 4D) to a state where the management ID “100” is registered (FIG. 8D). The management database 31 is not changed.
[0054]
According to the processing of FIG. 7, the management ID of the unnecessary file is deleted from the keyword database 30, the management ID revision status based on the management database 31 and the unnecessary management ID data 32, and the actual management ID in the keyword database 30. It is possible to achieve consistency with the status of reforms.
[0055]
According to the first embodiment, unnecessary file records are deleted from the management database 31 by the file deletion process of FIG. 3, and the file search processes of FIGS. 5 and 6 are performed based on the management database 31. Even when the keyword database cleaning process of FIG. 7 is not performed, unnecessary file attribute information is not acquired in the file search process of FIGS. That is, the search is blocked. Therefore, even if the process of actually deleting unnecessary file management IDs from the keyword database 30 (FIG. 7) is not performed each time, the file search process is performed assuming that the file has been deleted. Furthermore, unnecessary files are deleted from the keyword database 30 at a predetermined time, so that the load of file deletion processing can be absorbed at an appropriate time. Therefore, the response of the file deletion process can be improved. The effect increases as the data amount of the keyword database 30 increases.
[0056]
Further, since the keyword database 30 is not accessed in the file search process, the response of the file search process itself can be improved.
[0057]
Further, by deleting unnecessary files from the keyword database 30 at a predetermined time, it is possible to arbitrarily match the keyword database 30 and the management database 31. In addition, even when the two are not matched, the file search result is not affected as described above. Therefore, the unnecessary file batch deletion processing in the keyword database 30 can be performed at an appropriate time. Good.
[0058]
If the management ID of an unnecessary file can be specified by other means during the keyword database cleaning process of FIG. 7, the unnecessary management ID data 32 is not necessarily provided.
[0059]
(Second embodiment)
The electronic filing device according to the second embodiment of the present invention will be described below. The electronic filing device according to the second embodiment has the same configuration as the electronic filing device according to the first embodiment, and is as shown in FIG. Therefore, the same reference numerals are used for the same components as those in the first embodiment. In the second embodiment, the file copy process can be performed as compared with the first embodiment, and a part of the file deletion process is changed accordingly. Accordingly, the second embodiment of the present invention will be described with reference to FIG. 9 newly used for the file copying process and FIG. 11 instead of FIG. 3 for the file deletion process.
[0060]
FIG. 9 is a flowchart of file copying processing by the electronic filing device according to the second embodiment of the present invention. This process is executed by the CPU 1.
[0061]
First, the document ID and file ID of a file to be copied are designated (step S901), and it is determined whether or not the designated document ID and file ID are registered in the management database 31 (step S902). As a result of the determination, if the designated document ID and file ID are not registered in the management database 31, the present process is immediately terminated. On the other hand, if the designated document ID and file ID are registered in the management database 31, A management ID corresponding to the designated document ID and file ID is acquired from the management database 31 (step S903), and a record in which attribute information such as a new document ID, file ID, and file name is assigned to the acquired management ID is newly created. The new record is additionally registered in the management database 31 (step S904). Here, the same management ID is used because the contents of the file are not changed before and after copying.
[0062]
Next, the number of registration duplications for the management ID in the duplication management ID data 34 is counted up (step S905), and this process ends. Here, the duplicate management ID data 34 is information used in the second embodiment, and as shown in FIG. 10 (e), the duplicate management ID data 34 and the number of registrations are registered in the management database 31. The stored information is stored in the storage unit 6. The management ID is not registered in the duplicate management ID data 34 when there is no duplication registration, that is, when the duplication frequency is “1”, and is newly registered when the duplication frequency is “2” or more. . Therefore, in step S905, when the registration number of the record before copying is “1”, the management ID is newly registered, and when the registration number of the record before copying is “2” or more, The management ID overlap count is incremented by “1”.
[0063]
For example, when this process is executed by specifying the document ID as “90” and the file ID as “2” with the state shown in FIG. 2 as the initial state, the state shown in FIG. 10 is obtained. That is, a record in which a new document ID “1000” and a file ID “1” are allocated to the management ID “100” is added to the management database 31 shown in FIG. Becomes two (FIG. 10B). Further, the management ID “100” is newly registered in the duplication management ID data 34, and the duplication frequency is set to “2” (FIG. 10E). The keyword database 30, unnecessary management ID data 32, and missing number management ID data 33 are not changed.
[0064]
According to this processing, it is possible to copy a desired file without revising the data in the keyword database 30. Since the file search process is performed based on the management database 31, even if the keyword database 30 and the management database 31 are not matched, the search result is not affected.
[0065]
FIG. 11 is a flowchart of file deletion processing by the electronic filing device according to the second embodiment. This process is executed by the CPU 1.
[0066]
First, in steps S1101 to S1104, processing similar to that in steps S301 to S304 in FIG. 3 is executed.
[0067]
In step S1105, it is determined whether or not the management ID (unnecessary file management ID) acquired in step S1103 is registered in the duplicate management ID data 34. As a result of the determination, the acquired management ID is duplicate management. If it is registered in the ID data 34, the frequency of duplication of the management ID is counted down (step S1107), and this process is terminated. By processing in this way, registration of the management ID in the unnecessary management ID data 32 is also prohibited. Here, when the frequency of duplication of the management ID becomes “1” due to the countdown, the management ID registration itself is deleted from the duplication management ID data 34.
[0068]
On the other hand, if the acquired management ID is not registered in the duplicate management ID data 34 as a result of the determination in step S1105, the same processing as step S305 in FIG. 3 is executed in step S1106, and this processing is terminated. . That is, when the file to be deleted is not registered redundantly, the management ID is deleted from the management database 31 and registered in the unnecessary management ID data 32 as usual.
[0069]
According to the second embodiment, in the file copying process, the process is completed simply by adding a record in the management database 31 using the same management ID to the file having the same contents, and the keyword database 30 is not accessed. The response of the file copying process can be improved.
[0070]
In addition, since all the attribute information of the management ID registered in duplicate is acquired in the file search process, the accuracy of the search result can be ensured.
[0071]
In the file deletion process, when the file to be deleted is not registered redundantly, the same process as in the first embodiment is performed, and when the file to be deleted is registered redundantly, only the count of the duplication frequency is performed. Therefore, the file can be copied while maintaining the effect of improving the response of the file deletion process in the first embodiment.
[0072]
(Third embodiment)
The electronic filing device according to the third embodiment of the present invention will be described below. The electronic filing device according to the third embodiment has the same configuration as the electronic filing device according to the first embodiment, and is as shown in FIG. Therefore, the same reference numerals are used for the same components as those in the first embodiment. In the third embodiment, a part of the file deletion process and a part of the file search process are different from the first embodiment. In the third embodiment, a file restoration process is newly added. Accordingly, FIG. 14 is newly used for file restoration processing, FIG. 12 is used for file deletion processing instead of FIG. 3, and FIG. 13 is used for file search processing instead of FIG. Will be explained.
[0073]
FIG. 12 is a flowchart of file deletion processing by the electronic filing device according to the third embodiment. This process is executed by the CPU 1.
[0074]
First, in steps S1201 and S1202, processing similar to that in steps S301 and S302 in FIG. 3 is executed.
[0075]
Next, in step S1203, the same process as in step S305 in FIG. 3 is executed, and this process ends.
[0076]
That is, in this process, the management ID of the unnecessary file is registered in the unnecessary management ID data 32 as in the first embodiment, but the record of the unnecessary file remains without being deleted from the management database 31.
[0077]
FIG. 13 is a flowchart of file search processing by the electronic filing device according to the third embodiment. This process is executed by the CPU 1.
[0078]
First, in steps S1301 to S1303, processing similar to that in steps S501 to S503 in FIG. 5 is executed.
[0079]
In step S1304, it is determined whether the management ID acquired in step S1303 is registered in the unnecessary management ID data 32. As a result of the determination, the acquired management ID is registered in the unnecessary management ID data 32. If yes, the management ID is excluded from the search result (step S1305), and the process proceeds to step S1306. That is, the management ID is not searched and attribute information corresponding to the management ID is not acquired, and the subsequent processing is performed. Thereby, even if the management ID of an unnecessary file remains in the management database 31, it is possible to avoid the attribute information of the unnecessary file being acquired in the file search process.
[0080]
On the other hand, if it is determined in step S1304 that the acquired management ID is not registered in the unnecessary management ID data 32, the process immediately proceeds to step S1306.
[0081]
In step S1306, processing similar to that in step S504 in FIG. 5 is executed, and this processing ends.
[0082]
FIG. 14 is a flowchart of file restoration processing by the electronic filing device according to the third embodiment. This process is executed by the CPU 1.
[0083]
First, the management ID of the file to be restored is designated (step S1401), and it is determined whether or not the designated management ID is registered in the duplicate management ID data 34 (step S1402). As a result of the determination, if the designated management ID is registered in the duplicate management ID data 34, the process proceeds to step S1403, and the number of duplicates of the management ID is counted up. Thereby, the record of the file deleted from the state where the duplication degree is “3” or more is restored in the search process. That is, the state before the deletion is returned.
[0084]
Next, it is determined whether or not processing has been performed for all the specified management IDs (step S1407). If there is an unprocessed management ID as a result of the determination, the process returns to step S1401, while the specified management ID is determined. If the process has been performed for all of the above, this process ends.
[0085]
If the specified management ID is not registered in the duplicate management ID data 34 as a result of the determination in step S1402, it is determined whether or not the specified management ID is registered in the unnecessary management ID data 32 (step S1404). As a result of the determination, if the designated management ID is registered in the unnecessary management ID data 32, the management ID is deleted from the unnecessary management ID data 32 (step S1405), and the process proceeds to step S1407. As a result, the record of the file once deleted as unnecessary in the state where the duplicate registration is not performed is restored in the search process. On the other hand, if the designated management ID is not registered in the unnecessary management ID data 32, the designated management ID is newly registered in the duplicate management ID data 34 and the duplication frequency is set to “2” (step S1406). The process proceeds to step S1407. Thereby, the record of the file deleted in a state where duplication registration is not performed (the duplication degree is “1”) is restored in the search process.
[0086]
By this processing, the deleted file can be restored arbitrarily and easily.
[0087]
According to the third embodiment, in the file deletion process, it is only necessary to register the management ID of the file to be deleted in the unnecessary management ID data 32, and it is not necessary to access the keyword database 30 and the management database 31. The response of the file deletion process can be further improved.
[0088]
In the file search process, since unnecessary file records remain in the management database 31, the records are acquired once, but are excluded from the search results in the subsequent process. The same effect as that of the first embodiment can be obtained for the file search process without affecting the accuracy.
[0089]
In addition, since unnecessary file records are not actually deleted from the management database 31, the files can be easily restored. Furthermore, it is possible to appropriately restore the state before deletion according to the overlapping state of registration of the file.
[0090]
