Description

The present invention relates to a file management system and file management program. More specifically, the present invention relates to a file management system and a file management program for managing information on files uploaded from user terminals to file recording means.

With the spread of the Internet, techniques for searching (extracting) content such as files using keywords input by users as queries are being actively used. Specifically, after morphologically analyzing the file information and indexing it, content with a high degree of matching between the "indexed phrase" and the "input keyword" is searched.

Here, Japanese Patent Application Laid-Open No. 2002-300002 proposes a technique of adding metadata so that content can be easily searched for according to the purpose.

JP 2003-228569 A

However, the technique described in Patent Literature 1 is to "attach management metadata to content information when the first keyword group and the second keyword group have a predetermined matching degree or more". Therefore, although it is suitable for the purpose of adding general-purpose metadata to content, it is sufficient in terms of searching for content that meets the user's needs when targeting content created independently by the user. Hard to say.

That is, it is highly conceivable that content created independently by a user includes "words used only by the user who created the content" or "words used only within a specific organization." It is difficult to say that the technology described in Patent Document 1 is sufficient in terms of retrieving content that matches the user's request when targeting content that includes a word that is not "."

Further, the file management program of the present invention is a file for causing an information processing device to function as file management means for managing information of an uploaded file which is a file uploaded from a user terminal used by a predetermined user to a file recording means. In the management program, the file management means is configured to be able to access word information recording means configured to record information of a predetermined word, the name of the file uploaded to the file recording means, the file record Contents of files to be uploaded to the means, name of the directory in the user terminal where the files to be uploaded to the file recording means are stored, directory in the file recording means to store the files to be uploaded to the file recording means or description information of a directory in the file recording means in which the file uploaded to the file recording means is stored; When the extracted wording, which is the wording extracted by the means, does not match the recorded wording, which is the wording whose information is recorded in the wording information recording means, question information for making the user answer the information of the extracted wording a question information output means for outputting to said user terminal; and a wording information document for writing and recording information of said extracted wording in said wording information recording means based on answer information of said question information transmitted from said user terminal. and search means for searching the file recorded in the file recording means based on the wording recorded in the wording information recording means using the search information transmitted from the user terminal as a query.

Here, by having the wording information recording means configured to be able to record the information of the predetermined wording, the information of the wording (extracted wording) extracted by the wording extracting means can be accumulated.
Similarly, by being able to access the wording information recording means configured to be able to record the information of the predetermined wording, the information of the wording (extracted wording) extracted by the wording extracting means can be accumulated.

Also, the name of the file to be uploaded, the content of the file to be uploaded, the name of the directory in the user terminal in which the file to be uploaded is stored, the name of the directory in the file recording means in which the file to be uploaded is stored, or Description information of the directory in the file recording means in which the file to be uploaded is stored. It is possible to specify a judgment target for consistency with (recorded wording).

The file-related information includes "the name of the uploaded file, the contents of the uploaded file, the name of the directory in the user terminal where the uploaded file is stored, and the file recording means in which the uploaded file is stored. At least one of the name of the directory or the description information of the directory in the file recording means in which the file to be uploaded is stored”, the following cases can be mentioned (here, “file” is "Uploaded file" means "user-side directory" means "directory on user terminal where uploaded file is stored", "server-side directory" means "stored uploaded file (meaning "directory in the file storage means").
(1) When "file name" is included (2) When "file content" is included (3) When "user side directory name" is included (4) When "server side directory name" is included (5) (6) If two or more of the above (1) to (5) are included (7) In addition to the above (1) to (6), if further information is included Including

Here, "explanatory information of the directory in the file recording means in which the uploaded file is stored (explanatory information of the server-side directory)" means "name of the directory in the file recording means in which the uploaded file is stored (server The name of the side directory)” means supplementary information added to explain the directory in the file recording means in which the file to be uploaded is stored.

Further, when the extracted wording, which is the wording extracted by the wording extracting means, does not match the recorded wording, which is the wording whose information is recorded in the wording information recording means, question information for making the user answer the information of the extracted wording. to the user terminal, the extracted wording whose information is not recorded in the wording information recording means (in other words, the extracted wording that does not match the recorded wording) is provided to the user. can be asked for.

Further, by having a wording information writing means for writing and recording the information of the extracted wording in the wording information recording means based on the answer information of the question information transmitted from the user terminal, the extracted wording can be used (for example, uploaded Extracted wording is used as part of the name of the file to be uploaded, Extracted wording is used as part of the content of the uploaded file, Extracted wording is used as part of the name of the directory on the user terminal where the uploaded file is stored , Use the extracted wording as part of the name of the directory in the file recording means where the uploaded file is stored, Use the extracted wording as part of the description information of the directory in the file recording means where the uploaded file is stored It is possible to write the answer information from the user who has used it into the wording information recording means.

Further, by having search means for searching for files recorded in the file recording means based on the wording recorded in the wording information recording means using the search information transmitted from the user terminal as a query, the user's answer information can be retrieved. Based on this, file search is realized.

It should be noted that the "search information" here is not limited to character information as long as it is information that allows the search means to search for files. For example, it may be voice information or the like.

In the present invention, with respect to an extracted wording whose information is not recorded in the wording information recording means, the user who used the extracted wording is requested to answer, and based on the answer information obtained from the user himself/herself, the unrecorded extracted wording is recorded. is newly recorded in the wording information recording means, and the search means performs a search based on the wording recorded in the wording information recording means, realizing a file search that matches the user's request. be possible.
That is, for information not stored in the wording information recording means, the user who best understands the extracted wording (the user who used the extracted wording) is encouraged to accumulate the information, and the search is performed based on the information thus accumulated. Thus, it becomes possible to realize file retrieval that meets the user's request.

By the way, the wording information recording means is configured to be able to record synonym information, and the searching means searches the files recorded in the file recording means by using the synonyms of the search information recorded in the wording information recording means as queries. In that case, not only "file search using information (search information) sent from the user terminal as a query" but also "search using a synonym of the information (search information) sent from the user terminal as a query". As a result, it becomes possible to realize a file search that further meets the user's request.

Further, when a file is uploaded to the file recording means after being recorded in the wording information recording means by the wording information writing means, the extracted wording of the file recorded in the file recording means (upload file) is It means that it is recorded in the wording information recording means. Therefore, it is possible to realize a file search that matches the user's request for all uploaded files recorded in the file recording means.

<First embodiment>
[Description of system configuration]
FIG. 1 is a schematic diagram for explaining an example of the configuration of the file management system of the present invention. The file management system 1 shown in FIG. , and a file server (storage) 4 .
By installing the "file management program" of the present invention in the information processing equipment, it functions as the file management means 3. FIG.

The user terminal 2 here is configured to be able to access the file management means 3 via the Internet. Similarly, the file management means 3 is also configured to be able to access the file server 4 via the Internet.

The file management system 1 of this embodiment can be used by a person who is registered as a user in the file management means 3, and a user using the user terminal 2 can access (log in to) the file management means 3. ID and password will be required.

The file management means 3 includes a keyword recording means 31, a search index recording means 32, a keyword extraction means 33, a keyword confirmation means 34, a question information output means 35, a keyword writing means 36, and a file writing means. It has means 37 , indexing means 38 and search means 39 .

Here, the keyword recording means 31 is composed of "general dictionary data 31a" and "user dictionary data 31b".
The general dictionary data 31a records general words (for example, words listed in general dictionaries) and also records information relating to associations between words that are generally used as synonyms. there is Here, "association between words" means, for example, "sales = sales" and "tool = material" (in the present embodiment, when A and B are synonyms, "A = B”).
Information is recorded in the general dictionary data 31a in the initial state (in other words, the state before the user starts using the file management system of the present invention).

On the other hand, the user dictionary data 31b is configured to be able to record words not recorded in the general dictionary data, and is configured to be able to record information relating to associations between words used as synonyms by the user. Here, "association between words" is, for example, "Roanna".
No information is recorded in the user dictionary data 31b in the initial state (in other words, the state before the user starts using the file management system of the present invention).

After the keyword writing means 36 writes, the word is treated as a word (a known word) recorded in the keyword recording means.
In other words, the writing by the keyword writing means 36 causes the file management means 3 to learn unknown words, which are treated as known words after learning.

The file writing means 37 is configured to be able to upload files to the file server 4 .
In this embodiment, the file is uploaded by the file writing means 37 after confirmation processing by the keyword confirmation means 34 and writing processing by the keyword writing means 36 when the extracted keyword is an unknown word.

The index creating means 38 creates index information (index) extracted using a morphological analysis method based on the information of the file (upload file) uploaded to the file server, and records it in the search index recording means 32 . As dictionaries for analysis necessary for morphological analysis, the general dictionary data 31a and the user dictionary data 31b of the keyword recording means 31 are used in addition to the standard dictionaries of the general-purpose indexing means.

The index creation means 38 of the present embodiment includes (1) the name of the uploaded file, (2) the content of the uploaded file, (3) description information of the uploaded file, and (4) the name of the user terminal 2 in which the uploaded file was stored. An index is created from the name of the directory, (5) the name of the directory of the file server 4 in which the uploaded file is stored, and (6) descriptive information of the directory of the file server 4 in which the uploaded file is stored.
In addition, the index creating means 38 stores (7) information on the user who uploaded the upload file, (8) information on the user who downloaded the upload file, (9) information on the date and time when the upload file was uploaded, and (10) information on the upload file. An index is also created from information on the date and time of download, (11) information on the date and time when the uploaded file was updated, (12) information on the file server 4 where the uploaded file is stored, and (13) information on the thumbnail image of the uploaded file. do.

The search means 39 searches the index information (index) recorded in the search index recording means 32 using the character information (search information) transmitted from the user terminal 2 as a query.
For example, the character information (search information) may contain only one word (search keyword) or may contain a plurality of words. If the character information (search information) contains multiple words, the multiple words may be separated by spaces. In this case, multiple words may be used under an AND condition or under an OR condition.
Further, for example, character information (retrieval information) is not limited to words, and may be sentences or part of sentences.

The file server 4 is composed of a first file server 41 , a second file server 42 and a third file server 43 .
The first file server 41 is an in-house server (in-house server) installed in the organization to which the user of the file management system 1 of this embodiment belongs, and the second file server 42 and the third file server 43 are , is a server installed outside the company.
