Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to, for example, the knowledge and know-how of individuals, documents created by individuals, computer software, works such as paintings, and knowledge of fields owned by specific groups. And an information sharing system that makes the information public on a computer network and allows the information to be shared via the computer network.

[0002]

2. Description of the Related Art In recent years, electronic bulletin boards on computer networks, Internet homepages, and the like have been used as means for sharing information on computer networks. With the improvement of the network environment and the reduction in the price of information communication devices and storage devices, individuals and organizations can easily transmit and receive information using these means.

For example, a large number of homepages are established on the Internet, and a variety of information can be searched by using a search service on the Internet. In a local network,
For example, information can be transmitted and received within an organization using an electronic bulletin board on a personal computer.

[0004] Under such an environment, the Internet has come to provide information itself as a service. For example, a help desk, a contact point for inquiries from manufacturers' customers, provides contract users with
Some sites publish useful troubleshooting information. In such a help desk, the quality and quantity of the information to be provided leads to differentiation from other help desks and is important.

[0005] Regarding information sharing within an organization, it has become possible for individuals to directly transmit information without going through the conventional organizational hierarchy. Disclosure of information by individuals makes it easier for them to appeal their own characteristics and achievements. At the same time, when a large amount of high-quality information is shared, the intellectual productivity of the entire organization is improved.

[0006]

The above-mentioned information sharing means has almost no function for maintaining the quality of information. However, the quality of information deteriorates with time, such as incorrect contents. For example, in the troubleshooting information at the help desk, it is necessary to check the contents due to a change such as a functional improvement of the product. The information sharing means does not have a function to support such inspection.

[0007] For example, in the homepage of the Internet, the management of the information described therein is left to the creator of the homepage.
The review is not actively encouraged by the system.
An electronic bulletin board may have a function of automatically deleting old information, but it has an adverse effect when there is useful information that is old. Such a function is good for flow information (information for communication such as communication information), but cannot correspond to stock information (information for accumulation and long-term sharing).

[0008] After all, in order to maintain the quality of information in the conventional information sharing system, all of the accumulated information must be reviewed periodically and corrected as necessary. This cannot be said to be a very practical means in the recent situation where information transmission is simplified and a large amount of information is accumulated.

[0009] Therefore, in the conventional information sharing, it is necessary to select either to accumulate a large amount of low-quality information that is not known to be correct or useful, or to reduce the amount of information in order to maintain the quality. And could not share a large amount of information that could be guaranteed to be useful to users.

[0010] The present invention has been made in view of the above problems, and detects what needs to be reviewed from stored information, assigns a priority to the information, and notifies the administrator of the shared information of the information. It is an object of the present invention to provide an information sharing system capable of efficiently reviewing information.

[0011]

In order to solve the above-mentioned problems, an information maintenance and management apparatus for an information sharing system for accumulating and sharing information is provided. Reliability prediction means for predicting the reliability of the information at a time, validity calculation means for calculating the validity of the information based on a user operation on the information, and information predicted by the reliability prediction means A detection unit for detecting information to be updated based on the reliability of the information and the validity of the information calculated by the validity calculation unit,
There is provided a presenting means for presenting information to be updated detected by the detecting means together with a reason for updating.

That is, it is determined by the reliability determining means 1 how much the contents of each piece of information stored are likely to be correct, and how much each piece of information stored by the validity determining section 2 actually helps the user. The detection unit 4 identifies information that needs to be reviewed based on the results of the reliability determination unit 1 and the validity determination unit 2, and the presentation unit 3 identifies the information that needs to be reviewed extracted by the detection unit 4. By presenting the information together with the results of the reliability judging unit 1 and the validity judging unit 2, the administrator of the information sharing system is notified of what aspect the information needs to be reviewed and the priority of the review. Things.

[0013] An information maintenance and management apparatus for an information sharing system for accumulating and sharing information is provided. The information maintenance and management apparatus analyzes the contents of the stored information and generates information based on a description that may include information with low universality. Determination means for determining the reliability of the information, vocabulary knowledge describing the relationship between terms related to information and the need from the user such as urgency and reference frequency, based on the reliability determined by the determination means A detection unit for detecting information to be updated, and a presentation unit for presenting the information to be updated detected by the detection unit together with the reliability.

Is given. The system includes a storage unit 8
The information that satisfies the input search request is searched for from the information stored in the server, and the result is output on the main screen 53. FIG. 5 is an output example of a search result. If there is a plurality of pieces of information that satisfy the search request, the system displays a list of the titles of the pieces of information. The user specifies desired information by selecting information to be referred from the subject list.

In FIG. 5, a title list of a plurality of information is displayed on the main screen 53. FIG. 6 is a display example of a screen on which the user is referencing the information of FIG. 5 via the information reference unit.

A user can input an evaluation into information presented by the system in response to a search request. FIG.
5 is an embodiment of a user interface for a user to input an evaluation for information via an input / output unit 9 and a presentation unit 3. Users By pointing a button 72 such as “very useful” or “useful” on the evaluation input window 71, an evaluation for the information can be input. It is also possible to input more detailed evaluation on the comment input form 73.

Next, the presentation unit 3 of the information sharing system 10 shown in FIG. 1 detects information that needs to be reviewed from the value calculated as a scale factor using the results of the reliability prediction unit 1 and the effectiveness calculation unit 2, and detects the information. The information maintenance and management method that presents the information that has been reviewed together with the reasons that need to be reviewed will be explained.

FIG. 7 is a flowchart showing the flow of the process in which the presentation unit 3 presents information that needs to be reviewed to the administrator. First, the presentation unit 3 obtains the reliability x (i) of certain information from the reliability prediction unit 1 (step S5).
01).

Hereinafter, a method in which the reliability prediction section 1 predicts the reliability of the information stored in the storage section 8 will be described. The total number of information stored in the storage unit 8 is N, and the set of information is D = ｛d
(1), d (2),..., D (N)}.

Further, for each element of D, the number of times of review is represented by C = {c (1), c (2),.
(N)｝. That is, the i-th element d (i) of D
Has been reviewed c (i) times from the registration to a certain point in time.

Time (days) when d (i) was updated
_間隔 t _i1 , t _i2 , t _{i3 ,.
tic (i)} , _{tic (i) +1} }.

Here, _{tic (i) +1} represents the number of days that have elapsed since the last change was made. The default value of the review interval set by the administrator is T
H.

The reliability estimating unit 1 obtains the number c (i) of times data d (i) has been reviewed. If c (i) = 0, that is, if the information d (i) has not been reviewed since registration, let _ti1 / TH be the reliability x.

If c (i) ≠ 0, the next review interval is predicted from the previous review interval. 0 <j <
For each j that is c (i) +1, p _i (j) × t _ij
Is calculated. This is referred to as TH (i).
(1) Here, p _i (j) is a parameter of a weight used for reliability prediction. For example, p _i (j) = a _i × j + b _i
... It is represented by the formula (2).

Also, p _i (1) + p _i (2) + p
_{i (3) + ... + p} i (c (i)) = 1 satisfy the condition that. In the present embodiment, the weight parameter is mapped on a single linear equation determined by the equation (2), but the parameter is not limited to this.

For TH (i) obtained in (1), t
_{ic (i) + 1} / TH (i) is calculated, and the reliability x
(I). The reliability x (i) has a value of 0 when information is registered or reviewed, and thereafter increases with time. Information whose reliability value exceeds 1 is information that has not been reviewed even after the review time predicted by the system.

Next, from the validity calculation unit 2, the validity y of the information is obtained.
(I) is obtained (step S502). Hereinafter, a method in which the validity calculating unit calculates the validity of the information will be described. The number of times the user has referred to the information d (i) stored in the storage unit 8 is r (i).

Further, the evaluation value e (i) of the information d (i) is calculated from the evaluation input by the user with respect to the information in the screen example shown in FIG. In the example of FIG. 7, evaluations such as “very useful”, “useful”, “lack of information”, and “information is old” can be input for the information. Find the value e (i). Note that E = {e (1), e (2),..., E (N)}.
And

The operation performed by the user on the information d (i) is {o _i1 , o _i2 , o _i3 ,..., O _{ir (i)} }. Here, r (i) is the number of operations performed on the information d (i). Further, a time made of each _{operation, {T i1, T i2,} T i 3, ..., T ir (i)} and.

For each operation o _ij , an evaluation value v
(O _ij ) is defined as follows. v (o _ij ) = 1 (when o _ij is a reference) v (o _ij ) = 2 (when o _ij is an evaluation “useful”) v (o _ij ) = 3 (o _ij is evaluation “very useful” If the current time is tt, the score e of the information d (i)
(I) is calculated as follows. e (i) = v (o _i1 ) / (tt−T _i1 ) + v (o _i2 ) / (tt−T _i2 ) +... + v (o _{ir (i)} ) / (tt−T _{ir (i)} ). (3) Finally, the validity y (i) is obtained by a calculation formula of y (i) = e (i) / AVE (E) (4).

Here, AVE (E) is the average value of e (i) for all data stored in the storage unit 8. The effectiveness y (i) indicates a high value when information is frequently referred to recently and a high evaluation is obtained.

The procedure for determining whether the information should be reviewed by the detecting section 3 based on the reliability x and the validity y of the information calculated by the method described above will be described below.

The presentation unit 3 determines the reliability x (i) of the information,
From the effectiveness y (i), w (i) = (x (i) × x (i) +
y (i) × y (i)) ^1/2 (5) is obtained (step S503).

This w (i) is compared with a predetermined threshold value TH1 (S504). FIG. 9 shows x (i),
This is a two-dimensional space having y (i) as axes. Where w (i) is the distance from the origin to a certain coordinate, w
Whether (i) is larger than the threshold value TH1 results in whether or not (i) is inside the circle 91 in the two-dimensional space. w (i)
The information d (i) plotted outside the circle is information that needs to be reviewed, and the information d (i) plotted inside the circle is considered to be information that does not need to be reviewed.

If w (i) is smaller than the threshold value TH1, the system checks whether the reliability x is larger than 1 (S505).

If greater than one, the information d (i) has exceeded the review period predicted by the system. Also, w
Since (i) is small, it is considered that the effectiveness of d (i) is not so high. Therefore, the system performs processing such as lowering the search priority of the information d (i) or automatically deleting the information d (i) (S509).

When w (i) is larger than the threshold value TH1, the presentation unit 3 obtains a reason for reviewing the information d (i) (S50).
6).

First, it is checked whether or not the reliability x (i) is larger than 1. If x (i)> 1, information d
(I) is information that has exceeded the review period predicted by the system and has received some high evaluation from users. Therefore, the presentation unit 3 searches the past evaluation history added to the information d (i), and obtains a usage state such as “frequently referenced” or “highly evaluated”. This allows
Determine the reason that the review period has passed, but the evaluation is high.

Also, despite x (i) <1,
If w (i) is greater than TH1, the validity y
(I) shows a high value, that is, it can be said that the information d (i) has recently received a high evaluation. Need to do that ". Further, the result of the number of references and the value of the evaluation obtained from the evaluation history can be added to the reason.

Next, the presentation unit 3 requests the administrator to correct or delete the contents of the information (S507). Here, the reason determined in the previous step S506 is also presented.

FIG. 10 is a display example of a screen requesting the administrator to correct or delete information. On the information management request window 100, attributes 101 such as the ID, title, and author of the information to be corrected / deleted are displayed.
02 is displayed. The administrator has the option to delete information,
By instructing the modification button 103, the information can be modified / deleted.

Further, by instructing the notification cycle change button 104, an instruction to extend the notification cycle by the presentation unit 3 can be given, that is, the value of _{ai in} the equation (2) can be reduced.

FIG. 11 is another display example of a screen requesting the administrator to correct or delete information. In this example, w (i) for all information is calculated, and presented in descending order of the value. In addition, along with the title of each information,
The value of w (i) for the information and the reason why the correction / deletion is required are presented. As a result, a list of information that needs to be corrected or deleted immediately can be presented to the administrator in the order in which the information needs to be reviewed.

In the example of FIG. 11, w (i) is displayed as a numerical value. However, in this embodiment, the display method is not limited to this method. For example, a bar graph may be displayed instead of a numerical value, or an arrow may be displayed as a vector on the x (i), y (i) plane.

The reason why it is determined that the correction is necessary is not limited to the method shown in FIG. For example, instead of directly displaying the reason, a method of changing the character of the title portion or the color of the bar graph display according to the type of the reason may be considered.

Next, the presentation unit 3 corrects or deletes the contents of the information according to the operation of the administrator, and then the reliability prediction unit 1 and the validity calculation unit 2 receive an operation related to the information. Notify that

The reliability prediction unit 1 changes the parameters used for reliability prediction according to the contents of the notification (S
508). In this embodiment, (2) determining expression of the weight parameters shown in _equation in _{p i (j) = a i} × j + b i,
Changing the slope _{a i} and the initial value _{b i.} If there is an indication that the period of notice shorter increase the value of a _i reduces the value of a _i in the case where it is instructed to be longer. Accordingly, b is set so that the sum of p _i (j) becomes 1.
Adjust the value of _i .

In the description of steps S501 and S502 in the flowchart of FIG.
Although the method for determining (i) and the effectiveness y (i) has been described, the method for determining reliability and effectiveness is not limited to this in the present invention.

For example, in the process for obtaining x (i) in step S501, equation (2) for determining the weight parameter
By setting p _i (j) = 1 / c (i), the average of the review intervals up to that time can be used as the predicted value of the next review interval.

When calculating TH (i) in (1), TH is calculated not by adding all js satisfying 0 <j <c (i) +1, but by adding a predetermined constant m times. It is also conceivable to obtain (i).

Further, the number of times of review of information d (i) X =
{1, 2, ..., c (i)} and the interval Y between each review operation
= {T _i1 , t _i2 ,..., _{Tic (i)} } is approximated as a regression line Y = AX + B, and using the parameters A and B of this line, the time interval until the c (i) + 1-th review , And using that value as TH (i).

In the processing for obtaining y (i) in step S502, the score for each evaluation content when determining the value of v (o _ij ) is not limited to the numerical value of this embodiment. Also, e
The formula (3) for calculating (i) is not limited to this calculation method. Also, in equation (4), e (i) for all data
Is normalized, but it is also possible to normalize with a predetermined constant instead of the average value.

The method of inputting an evaluation to information by the user shown in FIG. 7 is not limited to the method of the present embodiment as to the type of evaluation to be input or the input method. Further, an interface for evaluation input as shown in FIG. 7 is not essential for realizing the present invention. For example, it is also possible to calculate the validity only from the reference number of information without using the interface for evaluation input. In this case, V (o _ij ) used in the equation (3) may be set as a constant.

This content is not limited to the step of changing the parameters for calculating the reliability and validity based on the operation result shown in step S508. The present invention does not limit whether step S508 is performed.

Next, in such an information sharing system, in order to update the document content when the registered document content becomes old or incorrect, the document content is analyzed.
A flow of processing for detecting a document that needs to be reviewed and presenting the document to the system administrator will be described.

FIG. 19 shows the contents of the document analysis knowledge 128 referred to when the document is analyzed by the document analysis unit 123.
FIG. 19 shows document analysis knowledge used to detect, for example, old document contents. Reference numeral 190 denotes knowledge for classifying the description of the document contents.
93, and is defined as expression classification: :( sub classification): expression set.

For example, among the expressions representing “time”, expressions representing “period” include “from <date> (expression pattern representing time expression) to <date>” and “<dat”.
e>, “<any> (unspecified expression pattern) period”, and “when” are defined. 1
Reference numeral 91 denotes a definition of an expression pattern described in the knowledge described in the knowledge 190, which is composed of an expression pattern identifier 194 and definition contents 195.

For example, the expression <date> is expressed as “<
num> year ”,“ <num> month ”,“ <num> day ”
(<Num> is a numerical value) matches any or all of the three expressions (() is a group of expressions,
[] + Indicates that it matches one or more expressions in the expression group), “<num> months”,
Defines to match any expression of "<num>week".

The document analysis unit 123 analyzes a document with reference to such document analysis knowledge. First, a morphological analysis is performed on the registered document, the document is decomposed into morphemes, and it is checked whether each morpheme matches the expression pattern of the document analysis knowledge 128. If there is a match, the expression classification is added as additional information at the position where the matched expression appears in the document.

FIG. 20 shows the contents of the vocabulary knowledge 129 referred to when presenting recommended information at a certain time or estimating frequently searched information, for example. Vocabulary knowledge is described by a set of terms 201 and constraint descriptions that appear in the document. In this case, for example, a description of Hatsumode indicates that it is closely related to December. For example, since it is often referred to in December, the content must be reviewed before December. Recommendation information in December It can be used as a presentation. In addition, constraints described in vocabulary knowledge include urgency, such as whether the term is related to business at all times or related to frequently referenced documents.

The reliability judging section 124 judges the reliability of the registered contents by referring to the document analysis result and the vocabulary knowledge. The information with low reliability is, for example, old information. Therefore, judging whether information is old is one example of judging reliability. As a method of determining whether or not the information is old, the analysis result of the document analysis unit 123 includes, for example, an expression whose expression classification is time, money, person / organization, document, address (address, telephone number, URL, etc.). Document. In response to this result, the review information detection unit 125 presents the document that needs to be reviewed to the system administrator, and urges the correction.

FIG. 21 shows the flow of processing of the reliability judgment section 124, the review information detection section 125, and the detection information provision section 126. First, the document is analyzed (S211), and the expression classification is extracted (S212). In the case of this embodiment, since it is an example of determining whether or not the contents are old, it is checked whether or not the expression classification is likely to change over time (S213). If there is a corresponding expression classification, it is stored in the corresponding document list (S
214). If not, the next document is inspected (S215).

Next, referring to the vocabulary knowledge of the document having the corresponding expression classification, it is checked whether or not there is a description that matches the vocabulary in the document (S216). In the case of this embodiment, contents having a high relevance to the current time are inspected (S21).
7). For example, if the current time is December, “period = 1
Inspection is made to see if the term “February” includes a vocabulary such as “Year-end adjustment”, “Year-end party”, or “Banquet”.

If there is a corresponding document, the priority of the presentation order is raised (S218). This process is performed for all the documents, and the documents stored in the last document list are rearranged in order of priority and presented (S219).

FIG. 22 shows an embodiment of the display screen of the detection information providing unit 126. A list of documents that need to be reviewed and detected by the review detection unit 125 is displayed in order of priority. Reference numeral 220 denotes the title of the document, reference numeral 221 denotes an expression classification indicating the reason for the modification, reference numeral 222 denotes a priority, and reference numeral 223 denotes an excerpt of a review part (a part where an expression pattern of the expression classification appears). For example, the document “payment of short-distance daily allowance” has the expression classification of money and the priority is “always urgent”. Always-emergency indicates that the degree of urgency is high because it is frequently referred to regardless of the season.

On the other hand, the “method of purchasing a commuter pass” is always referred to, but is “always” because the frequency is low. Also,
In the “adjustment of short-distance daily allowance”, since the portion of “daily allowance of 1000 yen” is an expression pattern corresponding to the expression classification, the relevant portion is displayed in reverse.

FIGS. 23 and 24 are examples of screens presenting a review document to the system administrator. The part that needs to be reviewed, that is, the part whose expression classification matches the item that needs to be corrected is inverted and displayed (230). In this case, 100
It is urging the review where the monetary expression of 0 yen appears. On the other hand, the system administrator can make the correction by himself, but in this example, "correction request" is selected from the menu 231 to urge the information poster to make the correction. Then, as shown in FIG. 24, an additional information input window 242 is displayed, in which the content of the correction request is described and transmitted to the information poster. (Third Embodiment) Next, a third embodiment of the present invention will be described. FIG. 25 shows a functional configuration of an information maintenance / management method according to the third embodiment of the present invention.

This information maintenance / management system is used at a customer consultation desk for answering inquiries from customers, and creates a generalized assumed inquiry example of frequently inquired contents from the history of individual inquiries. It is published as publication document data that can be searched directly by customers.

[0092] The public database 251 stores information that can be made public and directly searched by customers. As in the first embodiment, a logical expression of a keyword and a natural language sentence can be searched as a search request. For example, in response to a natural language sentence search request, similar information can be searched using the angle between the independent word vector extracted by morphological analysis and the independent word vector of each information in the public database 251 as the similarity. (The closer the angle is to 0, the more similar it is determined).

The closed database 252 stores inquiries sent to the customer consultation desk from routes other than the public database 251 and the contents of answers to the inquiries by the customer consultation desk staff.

The validity calculating section 253 applies the contents of access to the public database 251 by the user to the private database 252, and obtains the validity of each information in the private database 252 based on the result.

The detecting section 254 detects information to be moved to the public database 251 in the closed database 252 based on the validity obtained by the validity calculating section 253. The presentation unit 255 presents the information detected by the detection unit 254 together with the result of the effectiveness calculation unit 253.

Hereinafter, the third embodiment will be described in detail.
FIG. 26 is an example of information stored in the public database 251. Here, assumed inquiry cases that frequently occur with respect to a certain product group are accumulated. FIG. 27 is an example of information stored in the private database 252. Here, the contents of inquiries sent to the customer consultation counter by telephone, facsimile, etc. and the contents of answers to the counterparts in response to the inquiry are stored.

Information in the private database 252 is log information of an inquiry sent to the customer consultation desk.
It is not always high-quality information that is meaningful to other customers. Since the disclosure of low-quality information leads to a decrease in service for the customer consultation desk, the closed database 252 is kept closed to the customer here.

Now, it is assumed that the user inputs an inquiry shown in 281 in FIG. 28 to a search unit different from the present invention. The search unit 254 searches the public database 251 by a known search method, and presents the result to the user. In this case, the query obtained by searching the public database 251 as described above is sent to the validity calculating unit 25.
3 is input.

The validity calculating section 253 having received the input of FIG. 28 calculates the validity of the information in the private database 252 according to FIG. Here, it is assumed that the search performed by the effectiveness calculation unit 253 is a conventionally known method. The input to the validity calculation unit 253 may be other than an inquiry to the public database 251.

[0100] For example, if the user
When the inside information is browsed, the content of the browsed information such as 282 may be input to the effectiveness calculating unit 253. In this case, the validity calculation unit 253 may perform a search called similar document search. That is, instead of the user inputting a natural language sentence search request, the viewed document may be searched as a search request.

SCORE in FIG. 29 is obtained, for example, as follows. SCORE = (11-RANK) * s (11
-RANK). Here, RANK is the rank in the secret database in the search by the effectiveness calculation unit 253. S (n) is a step function, and when n> 0, s (n) =
When 1, n ≦ 0, the value s (n) = 0.

That is, the information ranked first in the search is S
CORE is 10, and every time the rank goes down, 9,
8, ... SCORE of the 10th place information is 1 and 11
SCORE is 0 for all information below the order.

For example, 271 in FIG.
Assuming that the second place is obtained in the search by 53, SCORE becomes 9, and the validity of 271 becomes 32 according to FIG. As a result, the information in the private database 252 is as indicated by 301 in FIG.

The SCORE may be determined based on other criteria. For example, using a method that can obtain not only the rank but also the score and the similarity between the search request and the information as a search, the score is calculated as S
It can be considered as a CORE standard.

In response to the result of the effectiveness calculating section 253, the detecting section 254 detects information to be moved to the public database 251 in the private database 252 according to FIG. THRESHOLD in FIG. 31 is, for example, THRE
SHOLD = 30.

That is, the detecting unit 254 detects information in the private database 252 corresponding to the SCORE being selected as the first place three times for the input inquiry as information to be moved to the public database 251.

For example, reference numeral 301 in FIG. 30 has a validity of 32 and is larger than THRESHOLD = 30 here, so that it is detected as information to be moved to the public database 251 according to FIG. THRESHOLD may be determined based on other criteria. For example, another constant may be used, or THRESHOLD may be determined by averaging SCORE at the number of times of input.

The presentation section 255 presents the information detected by the detection section 254 together with the effectiveness calculated by the effectiveness calculation section 253 to the person in charge of the customer consultation desk. FIG. 32 shows an example of presentation by the presentation unit 255.

As a result, the person in charge of the customer consultation desk can transfer the information in the non-public database 252 to the public database 2
When moving to 51, the content of the presentation by the presentation unit 255 can be used as a clue.

In this embodiment, the public database 251 and the private database 252 may be physically the same database. By holding a flag indicating whether or not to be made public for each data, the public database 251 and the private database 252 can be logically distinguished.

In such a configuration, the public database 2
51 and the search performed by the effectiveness calculation unit 253 on the closed database 252 are the same.
It is sufficient to discriminate whether to present to the user or use by the validity calculating unit 253 based on the flag indicating whether or not to make the information public. By reducing the number of search processes, the load on the system is reduced and the processing speed is improved, so that maintenance and management can be performed in real time. At this time, the rank at the time of obtaining the SCORE may be the rank of the information of the non-public database in the information of both the public database and the non-public database.

When the public database 251 and the private database 252 are physically the same database, the administrator can transfer the information of the private database 252 to the public database 25 in accordance with the presentation contents of the presentation unit 255.
When moving to 1, the processing only needs to change the flag indicating whether or not to make the information public, so that the load on the system is also reduced.

Alternatively, it is also possible to accumulate, as a log, inquiries from users and information browsed, which are input to the validity calculation unit 253, and use them to perform maintenance and management in batches. By doing so, the processing can be performed collectively, for example, at night when there are few inquiries from the user, so that when there are many inquiries from the user, the load on the system related to maintenance and management is reduced.

The processing in the embodiment of the present invention can be realized by a computer-executable program, and the program can be realized as a computer-readable storage medium.

The storage media in the present invention include a magnetic disk, a floppy disk, a hard disk, and an optical disk (CD-ROM, CD-R, DVD).
Etc.), a magneto-optical disk (MO or the like), a semiconductor memory, or any other storage medium that can store a program and that can be read by a computer.

An OS (operation system) running on the computer, database management software, MW (middleware) such as a network, etc., realize the present embodiment based on instructions of a program installed in the computer from the storage medium. May be executed.

Further, the storage medium in the present invention is not limited to a medium independent of a computer, but also includes a storage medium in which a program transmitted via a LAN, the Internet or the like is downloaded and stored or temporarily stored.

Further, the number of storage media is not limited to one, and the case where the processing in the present embodiment is executed from a plurality of media is also included in the storage medium of the present invention, and the configuration of the media is any configuration. Good.

Note that the computer in the present invention is:
The computer executes each process in the present embodiment based on a program stored in a storage medium, and may have any configuration such as an apparatus such as a personal computer or a system in which a plurality of apparatuses are connected to a network. Is also good.

The computer in the present invention is not limited to a personal computer, but also includes an arithmetic processing unit, a microcomputer, and the like included in an information processing device, and is a general term for devices and devices capable of realizing the functions of the present invention by programs. are doing.
