Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document management system, and more specifically, in a document management system for managing document data files on a server in a server / client format, registration and approval of documents using a database. The present invention relates to a document management system that handles a document management flow of issuance and receipt, and a document management system that registers and searches document data files using keywords as document attributes.

[0002]

2. Description of the Related Art Conventionally, registration, approval, issuance, and receipt of a document data file handled in a workflow have been sent to each person in charge (user) and processed mainly using electronic mail. Therefore, the document data file of the master moved on the network and could not be centrally managed on the server. As a prior art similar to the technical idea of the present invention, for example, a document creation management system reported in JP-A-4-357558 or JP-A-7-21127.
The authentication confirmation system reported in Japanese Patent Publication is cited.

The former document creation management system reported in Japanese Patent Application Laid-Open No. 4-357558 has a first area in which data can be read out only by a person who has a read right at a predetermined portion of a form. Each of the second areas in which only the person who has the write right can write data is set to one or a plurality, and for example, even if it is one slip, the reading or writing of data is restricted to the specific area. It was made possible. In the latter, the authentication confirmation system reported in Japanese Unexamined Patent Publication No. 7-21127 is such that a plurality of users who share information using cooperation means authenticate the signature encrypted by the encryption means by the authentication confirmation means. This makes it possible to support group authentication.

The structural differences between the present invention and the conventional document creation management system will be described. In the present invention, registration, approval, and
The history of issuance / receipt is managed by the database, whereas the conventional document creation management system does not manage the history itself, but manages the history of registration / approval / issuance / receipt for the document data file. I haven't.

Next, a description will be given of the difference in operation and operation based on the difference in structure between the present invention and the conventional document creation management system. In the present invention, the history of registration / approval / issue / receipt can be retained for the document data files of all formats, whereas in the conventional document creation management system, the history of only the document data files of a certain fixed format. Can only hold.

Next, the structural difference between the present invention and the conventional authentication confirmation system will be described. Although the present invention does not require cooperation with an email system,
In the conventional authentication confirmation system, it is essential to cooperate with the electronic mail system. Further, according to the present invention, it is not necessary to perform the encryption for checking the tampering of the document data file.

Next, differences in operation and operation based on the difference in configuration between the present invention and the conventional authentication confirmation system will be described. In the authentication method of the conventional authentication confirmation system, there is a possibility that the master document data file being approved may be lost due to a failure of the network system or the like. Further, in the conventional authentication confirmation system, since the approval information is included in the document data file, there is a risk of tampering at all times.

Conventionally, in order to search a document or record registered in a database, one or a plurality of keywords under the control of the same dimension having no category classification are selected, and the selected keywords are AND, OR, etc. The search was performed by generating a search expression by combining using the operator of. Prior art similar to the technical idea of the present invention includes, for example, a search device reported in Japanese Patent Laid-Open No. 62-287337 and an information search method reported in Japanese Patent Laid-Open No. 6-176071.

The search device reported in the former Japanese Patent Laid-Open No. 62-287337 refers to a keyword dictionary that stores information about keywords for phrases registered in the Kana-Kanji dictionary at the time of Kana-Kanji conversion, and specifies a keyword. When a word or phrase is referred to, the priority is next judged by the keyword priority judgment means, and based on the result, the keyword automatic registration means successively registers the word or phrase in the keyword storage means as the keyword of the target sentence. It is a thing. Further, the latter Japanese Patent Laid-Open No. 6-176071
The information search method reported in Japanese Patent Publication assigns a simple priority order to a plurality of search target data based on their identity, inclusion relationship, and hierarchical relationship, and assigns a collation code string in descending order of priority to that of oneself. The maximum value of the number of consecutively matched codes compared with the collation code string with a high priority from the beginning,
The code matching length of the matching code string is used.

Here, the structural difference between the present invention and the conventional search device will be described. In the present invention, the search keywords registered in the database are prioritized, whereas in the conventional search device, the priority is given to the keywords stored in the keyword dictionary to be compared with the search keywords. Is attached. Further, in the present invention,
While the invention has been invented with respect to a search method for searching a document data file, the conventional search device has been invented in terms of automating the input of a keyword when registering a document data file.

Next, a description will be given of the difference in action and operation based on the difference in structure between the present invention and the conventional search device.
According to the present invention, it is possible to prioritize the search for search keywords at the time of search. In the present invention, the keywords to be registered at the time of registration are classified into categories in advance, and a keyword dictionary is not necessary for operation.

Next, the structural difference between the present invention and the conventional information retrieval system will be described. In the present invention, the search keywords registered in the database are prioritized, whereas in the conventional information search method, the keywords stored in the keyword dictionary to be compared with the search keywords are prioritized. The points are ranked and the search method based on the prefix match search is premised.

Next, the difference in operation and operation based on the structural difference between the present invention and the conventional information retrieval system will be described. According to the present invention, it is possible to prioritize the search for search keywords at the time of search. In the present invention, the keywords to be registered at the time of registration are classified into categories in advance, and a keyword dictionary is not necessary for operation. In the present invention, theories of forward, backward, partial, exact match, etc. are not directly affected.

[0014]

In the above-described conventional document flow management method of document registration, approval, issuance, and receipt, the history of document flow management is not managed in the database, so all document data files are processed. Registration / Approval /
There was a problem that it was not possible to manage the history of issuance and receipt. In addition, since the master document is not centrally managed on the server, if the document is in the process of registration, approval, issuance, and receipt, the master document cannot be referenced and the document being processed is lost. There was a problem that there is.

In the above-described conventional keyword registration / retrieval method, since the retrieval priority for each category is not assigned to the keyword at the time of retrieval, there is a problem that the retrieval result intended by the user cannot be obtained. Further, since the keywords specified at the time of registration / search are not classified into categories, there is a problem in that the registered document data files can be classified into more easily categorized categories and a wider variety of searches cannot be performed.

Therefore, according to the present invention, the history of registration, approval, issuance, and receipt of all document data files can be managed by managing the history of document flow management in the database, and the master document is stored in the server. By centrally managing the above, a master document can always be referred to even when the document is being registered, approved, issued, or received, and a document management system that prevents the document being processed from disappearing is provided. The purpose is to Further, according to the present invention, a search result intended by a user can be obtained by giving a search priority to each keyword at the time of search, and a keyword specified at the time of registration / search is classified into categories to register. It is an object of the present invention to provide a document management system capable of performing a wide-ranging and wide-ranging search on document data files that are classified into categories that are easy to understand.

Since the history of the document flow management of the processing performed by the above is configured to be managed by the database of the server 3, it is possible to manage the history of registration, approval, issuance, and receipt for all the document data files. Further, the master document is centrally managed on the server 3 so that the processing states of registration / approval / issue / receipt of the document can be known and registration / approval / issue / receipt of the document can be performed. With this configuration, the master document can always be referred to even while the document is being registered, approved, issued, or received, and the document being processed can be prevented from being lost. Further, since the master document is configured not to be moved to each client 4, 5, it is possible to save the labor of copying the document in the process of processing and reduce the extra disk space.

Embodiment 2 In this embodiment, a document management system for searching a document data file by a keyword in managing the document data file will be described. The document management system of the present embodiment is similar to the document management system of FIGS. 1 to 5 described in the first embodiment, and therefore description will be made using this. 9 (a)-(d)
FIG. 9 is a diagram showing the concept of search processing in the keyword registration / search means shown in FIG. 4 of the second embodiment according to the present invention.
In the document management system of this embodiment, when registering a document file, keywords attached to the document file as document attributes are registered in the database on the server 3 by category classification, and the document file is later used by using the keyword. Search for. Here, the keywords are classified into a plurality of categories to form a keyword group. In addition, priority is assigned to each category.

FIG. 9A shows a keyword group added when the original file is registered. The "key a", "key b", "key a", and "key C" of the original file are registered. It is a keyword attached to the document. FIG. 9 (b)
The keyword group extracted from the keyword added to each document file is shown, the category 1 is the keyword group which consists of "key A", "key B", and "key C", and the category 2 is " It is a keyword group consisting of “key a”, “key b”, and “key c”, and category 3
Is a keyword group consisting of "key", "key" and "key". Categories 1 to 3 are prioritized. Category 1 has the highest priority with a priority of 1, category 2 has the second highest priority with a priority of 2, and category 3 has a priority of 3. As the third highest. FIG. 9C shows a document file group.

The original file shown in FIG. 9A is a document file to be registered. When registering the original file, "key a", "key b", "key a", and "key C" are set as the keyword group attached to the document file. There is a keyword group extracted and registered from the keyword group added to each document file on the system. This keyword group is classified into categories 1 to 3 as shown in FIG. Also, the priority is set from category 1 to category 3.

Document files registered in the system are stored in the document file group shown in FIG. 9C. File 1 has the keyword "key B", File 2 has the keyword "key C", File 3 has the keyword
The file 4 has a keyword of “key a”, the file 4 has a keyword of “key b”, the file 5 has a keyword of “key b”, and the file 6 has a keyword of “key a”.

In the search example of the file related to the original file in the above configuration, the search formula, the file to be searched, and the meaning of the search result will be described with reference to FIGS. 9 (a) to 9 (d). If the search expression is "key or OR key",
As a search key, a file having "key" or "key" is searched, and a file 6 having "key" and a file 4 having "key" are searched. It can be seen that the relationship between the two files, file 6 and file 4, and the original file is related to category 3. As described above, in the present embodiment, by classifying the keyword group into categories, it can be used for a search for knowing the relevance of the keywords.

When the search expression is "file related to original file in category 2", the keyword included in category 2 ("key a",
A file having the same keyword as "key b", "key c") is searched, and files 3 and 5 are searched.
As described above, in the present embodiment, by searching for a document related to the original file in category 2, the user can search by category without knowing the keyword of the original file.

When the search expression is "file related to original file in all categories", files having all keywords included in category 1 to category 3 as search keywords are searched for, and files 2, 3, and 5, file 6 is searched. In this case, a file having four keywords of the original file is searched, but the keyword “key C” is a category 2 including “key a” and “key b”, and a category including “key a”. Search priority is higher than 3. Therefore, it is understood that the file 2 has the highest priority among the four searched files. Thus, in the present embodiment,
By giving priority to categories, it is possible to give superiority to search results.

Next, FIG. 10 is a flow chart showing the file search processing by category in the client in the keyword registration / search means shown in FIG. First, the client 5 receives the keyword information for search from the information input by the user or added to the original file (step S31), and then determines whether or not there is a category classification based on the received keyword information. The determination is made (step S32). When the client 5 determines that there is no category classification (step S32), it ends the search.

When the client 5 determines that there is a category classification (step S32), it selects a keyword for search from the keyword group included in the category (step S33), performs a keyword search for the selected category, and sets the file group. The corresponding file is searched from (step S34).

Next, the client 5 checks the priority order of the categories and sets the search priority order by category for the searched files (step S35). Then, the searched files and the set priority order are set. Is reported as a search result (step S36).

In the document management system of this embodiment, keyword information is used as a search means.
The present invention is not limited to this, and since the type and number of keyword information is not specified, the keyword information can be freely added, deleted, changed, etc. as necessary such as personal name, department, type of document, etc. You may change to.

Further, in the document management system of the present embodiment, the keyword group is classified as the category information, but the present invention is not limited to this, and the category information is not particularly specified. The category information may be freely added, deleted, changed, etc. as necessary. Also, the number of categories and keyword groups is not specified.

As described above, in the present embodiment, since the keyword group is classified into categories, it can be used for a search for knowing the relevance of keywords. Further, since the document related to the original file in the category 2 is searched, the user can perform the search by category without knowing the keyword of the original file. Furthermore, since the priority is assigned to the category, the search result can be given an advantage. For example, when revising a document, it is possible to easily search for a document related to a department, a person name, etc. of the document to be revised.
