BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a server for searching a data file published on a network.

[0002]

2. Description of the Related Art In recent years, with the development of the Internet, it has become widespread for companies and individuals to publish homepages on the Internet. Although useful information can be obtained from these homepages, it takes a lot of work to find out the necessary information because so many homepages are open to the public. In order to alleviate such a situation, there are many search sites that search homepages using keywords on the Internet. At these search sites, software called a search engine is used to display the attribute information of the homepage as a URL (Unifo).
rm Resource Locator), and the home page information that matches the search condition specified by the user is extracted from the stored content.

[0003]

Such a search engine is very convenient, but since the number of publicly available homepages is too large, hundreds to tens of thousands of keywords are searched when a keyword is used as a search condition. Often the home page information of is extracted. In such a case, it takes a huge amount of labor and time for the user to check the contents of each home page. Although it is possible to reduce the amount of extracted homepage information by tightening the search conditions, there is a high possibility that useful homepage information will be leaked because it does not match the search conditions.
Further, it is considered that the same problem occurs when the information provided by each individual in the group is searched by the groupware. In view of the above, in the present invention, when searching a data file represented by a home page on a network, the data file information is widely extracted under the search condition, and the data file information necessary for the user is obtained with a small labor. The task is to make it possible.

[0004]

In order to solve the above problems, the present invention has the following constitution. The invention according to claim 1 is a data search server connected by a network to a plurality of administrator computers operated by individual data file managers and a searcher computer operated by a data file searcher. It has such a structure.
Note that the data file in the present application refers to a data group that is grouped by one piece of identification information, and includes not only a general file and data that constitutes one screen of a home page, but also a file group and a home page group in one domain. . Further, the administrator of the data file in the present application is sufficient if the person who knows the content of the data file is sufficient, and normally the provider of the data file is assumed, but the present invention is not limited to this.

First, the file information storage means stores the identification information and the attribute information of a plurality of data files in association with each other. As the attribute information, the name of the data file,
Examples include a summary of the content and all or part of the content. Then, the search condition acceptance means accepts the search condition from the searcher computer, and the data extraction means extracts from the file information storage means the identification information of the data file associated with the attribute information that matches the accepted search condition. . Next, the search condition transmitting means transmits at least a part of the search condition to each of the manager computers of the managers of the data files corresponding to the extracted identification information, and the corresponding information accepting means manages the management from the manager computer. The corresponding information indicating that the data file managed by the person satisfies the search condition is received. Then, the identification information of the data file managed by the administrator of the administrator computer that has transmitted the relevant information by the relevant data notifying means is transmitted to the searcher computer.

By doing so, the extraction of the data file is performed depending on whether or not the keyword is included, and the judgment of the administrator is performed by the conditional statement. In the present application, the keyword can be automatically extracted from the conditional sentence, and the conditional sentence and the keyword need not be separated.

According to a third aspect of the present invention, in the data search server, the deadline acceptance means receives a deadline from the searcher computer, and the deadline transmission means sends the deadline to the management computer. Further, the relevant information receiving means receives the relevant information until the deadline. By such an operation, the administrator is urged to respond by a fixed time limit, and the searcher can specify the time limit for obtaining the search result. In addition, the processing period in the data search server is limited.

According to a fourth aspect of the present invention, in the data search server, the message receiving means further receives message data from the administrator computer which transmits the relevant information, and the message transmitting means associates the message data with the relevant information. The received message data is transmitted to the searcher computer. With such a configuration, the administrator does not have to make a binary decision that the data file that he / she manages matches the search condition, but also a concrete intention such as what kind of point the data file matches. It will be transmitted to the searcher.

According to a fifth aspect of the present invention, there is provided a data search server connected by a network to a plurality of administrator computers operated by individual data file managers and a searcher computer operated by a data file searcher. This is a method for searching a data file, and the data search server performs the following operation. That is, the file information storing step stores identification information and attribute information of each data file, the search condition receiving step receives the search condition from the searcher computer, and the data extracting step stores the stored attribute information of the data file. A search is performed for a file that matches the search condition, and the identification information of the data file corresponding to this attribute information is extracted. And
At least a part of the search conditions is transmitted to each of the manager computers of the manager of the data file corresponding to the identification information extracted in the search condition transmitting step, and the manager computer manages the manager in the corresponding information accepting step. The corresponding information indicating that the data file to be transmitted corresponds to the search condition transmitted is received. Then, the identification information of the data file managed by the administrator of the administrator computer that has transmitted the relevant information in the relevant data notifying step is transmitted to the searcher computer. By such an operation, first, the data files are narrowed down from the search condition presented by the searcher, and the result of further narrowing down the narrowed data files by the administrator who manages these data files is transmitted to the searcher. It will be.

According to a sixth aspect of the present invention, the search condition includes a keyword and a conditional sentence, and the attribute information includes text data. Then, in the data extracting step, the text data including the keyword is searched, and in the search condition transmitting step, the conditional sentence is transmitted. With such an operation, the first search server narrows down the data by keywords, and further,
The data will be narrowed down by the administrator using conditional statements.

According to a seventh aspect of the present invention, in the data search method, the data search server further receives a deadline from the searcher computer in a deadline acceptance step, and sends the deadline to the administrator computer in a deadline transmission step. To send. Then, in the corresponding information receiving step, the corresponding information is received until the deadline has passed. By performing such an operation, the deadline for transmitting the relevant information is limited, the manager is urged to respond within the deadline, and the searcher determines the deadline for obtaining the search result. In addition, the time limit for processing by the search server is limited.

According to an eighth aspect of the present invention, in the data search method, the data search server further receives a message from the administrator computer that transmits the corresponding information in the message reception step, and in the message transmission step. The message received in association with the relevant information is transmitted to the searcher computer.

The send button 704 is a button for confirming the input data by selecting it with the pointing device and sending it to the search computer A. The corresponding information check box 703d
Is associated with the password of the user screen of the user who entered the search condition, the password of the operator screen and the expiration date information. When the check box is checked, the password of this user screen and the password of the operation screen Deadline information is transmitted as relevant information. This updated operator screen 700 is displayed when the operator sends a password from the initial screen and makes a transmission request.
It is transmitted via the P transmission unit 103. That is, the HP transmitting unit 103 constitutes a search condition transmitting means for transmitting at least a part of the search condition and also constitutes a deadline transmitting means for transmitting the deadline data.

The user HP generation unit 113 generates a user screen for notifying the search result. FIG. 9 shows an example of the user screen 900. On the user screen 900, a password 901 for this user screen, a condition display area 902 displaying the input conditional sentence and time limit, and homepage count information 9 extracted by the HP information extraction unit 112.
03, the number-of-responses information 904 in which there is a response from the operator based on the conditional sentence is displayed. Since the figure shows immediately after the user screen is generated, the number-of-responses information is 0. The generated user screen 900 is immediately transmitted via the HP transmission unit 103 to the user computer B which has transmitted the search condition and the deadline, and
It is stored in the P data storage unit 102. Further, the password 901 is the same as the operator screen 700, and the authentication code generation unit 1
08 is generated as a 7-digit alphanumeric character and becomes the file name when the user screen 900 is stored in the HP data storage unit 102.

The e-mail transmission unit 114 displays the operator screen 7
When 00 is updated, the corresponding operator is notified by e-mail that the operator screen 700 has been updated.
Specifically, the e-mail address of the operator is extracted from the operator master 106 based on the URL in the homepage information extracted by the HP information extraction unit 112, and "the user has extracted your homepage by searching. Send a fixed phrase such as ". The corresponding information receiving unit 115 is shown in FIG.
The password of the corresponding user screen, the password of the operation screen, and the deadline information as the relevant information transmitted from the updated operator screen 700 as shown in FIG.
If the deadline information of the information received by the corresponding information receiving unit 115 exceeds the current date and time, the corresponding information receiving unit 115 deletes the information as it is. The message reception unit 116 also displays the updated operator screen 700.
Receives message data sent from

When the relevant information accepting unit 115 and the message accepting unit 116 accept the data within the time limit, the user H
The P generation unit 113 extracts the user home page for which the relevant information is obtained from the HP data storage unit 102 based on the received user screen password, and updates the content. Specifically, the necessary information is acquired from the search HP information based on the password of the operator screen, and the extracted contents of the user screen are rewritten. FIG. 10 shows an example of the updated user screen 900. On the updated user screen, a response homepage display area 905 is added in addition to the password 901, the condition display area 902, the number information 903, and the response number information 904. The response homepage display area 905 includes a homepage title 905a in which a link is set to the homepage operated by the operator who has made a response, and a message display area 905b in which the message received by the message reception unit is displayed. This user screen is transmitted to the user computer via the HP transmission unit 103 according to a request from the user. That is, the HP transmitting unit 103 constitutes a corresponding data notifying means for transmitting the URL as the identification information of the homepage operated by the operator who has transmitted the relevant information, and
It constitutes a message transmitting means for transmitting a message.

Next, the data flow of the home page search system centering on the search server A having the above-mentioned configuration will be specifically described. FIG. 11 is a sequence diagram showing an example of the data flow of the entire system. This figure shows the data flow when the home page operator registers the home page in the search server A, the home page is searched, and a message is finally sent to the user. First, the home page operator sends home page information for registration through the registration screen linked from the initial screen to the search server A (S51). The search server A accesses the homepage registered based on the URL in the homepage information and collects at least a part of the text data from the homepage (S52, S5).
3). The collected data is stored in the search HP information storage unit 105 together with the homepage information. At this time,
The operator information is stored in the operator master 106. Further, the search server A creates an operator screen, displays the password there, and sends it to the operator computer B (S54). This completes the homepage registration process.

Next, the flow of information when the user searches the home page will be described. First, a user who wants to search a home page requests the initial screen by transmitting URL data of the initial screen through the user computer C (S55). In response to this, the search server A transmits an initial screen as shown in FIG. 4 to the user computer C (S56). The user inputs a keyword and a conditional sentence in the condition input area on the initial screen, selects a deadline, and transmits these data to the search server A (S5).
7). Upon receiving this, the search server A searches the homepage information from the search HP information storage unit 105 based on the keyword, receives the result, generates a user screen, and transmits it to the user computer B (S58). ). At the same time, the search server A updates the operator screen of the operator who operates the extracted home page. Further, the search server A notifies the operator's computer of the operator who operates the homepage extracted by the search via electronic mail that the user has searched (S59).

The operator who receives this e-mail calls the initial screen from the operator computer B, inputs the password, and requests the operator screen (S60). In response to this, the search server A transmits the operator screen (S6).
1). The operator's screen displays keywords, conditional statements, and deadlines entered by the user. If the operator reads the conditional statements and determines that the home page to be operated matches the conditional statements, the corresponding information check box is displayed. Check the box, enter the message and select the send button. As a result, the password of the user screen, the password of the operator screen, the date data of the deadline, and the message information as the relevant information are transmitted to the search server A (S62). Although there is only one homepage operator here, in reality, since a plurality of homepages are extracted by the search, the corresponding information and message will be transmitted from the plurality of homepage operators until the deadline. The search server updates the user screen C each time it receives the relevant information and message by the deadline. Then, the user requests the user screen from the user computer C when the deadline has passed (S63).
As a result, the homepage information and the message to which the operator responds are sent to the user computer C via the user screen (S64). Through the above operation, the user can obtain, from the enormous amount of homepage information, the one that the operator determines is appropriate.

Next, the operation of the search server A will be described. The homepage registration operation is a known operation, and thus its description is omitted. First, the operation of the search server A from receiving the search condition from the user to updating the operator screen will be described. FIG. 12 shows a flowchart showing this operation. In addition, H for search already
Necessary information is recorded in the P information storage unit 105 and the operator master 106, and an operator screen is also stored in the HP data storage unit 102 for each operator. Since the user first transmits the URL data of the initial screen, the HP transmission unit 103 accepts this URL data (s102), and H
Initial screen 4 as shown in FIG. 4 from the P data storage unit 102
00 is extracted and this initial screen is transmitted to the user computer C (s103). The user has this initial screen 40
From 0, a keyword and a conditional sentence are input in the search condition input area 401, and a deadline is selected and transmitted. In the search server A, the search condition receiving unit 110 receives the keyword and the conditional sentence, and the deadline receiving unit 111 receives the deadline (s104). The HP information extracting unit 112 searches the HP information storage unit 1 for search based on the received keyword.
From 05, homepage information including this keyword is searched and extracted (s105).

Then, a user screen 90 as shown in FIG. 9 including a display of the number of extracted homepage information items.
0 is generated (s106). The generated user screen 900 is transmitted to the user computer B, and the HP
The data is stored in the data storage unit 102 (s107). Also,
At the same time, as shown in FIG. 8, a response information input area 703 is added to the operator screen 700 of the operator of the home page extracted by the search based on the search condition and the deadline information entered by the user, and a send button 704 is also added. Is added (s108). When the operator screen 700 is updated, an email notifying that the home page operated by the operator has been extracted by the search by the email sending unit 114 is sent to the operator computer B as an email (s109). Thus, the operation from the acceptance of the user's search condition to the update of the operator screen is completed.

Next, the operation until the operator responds to the user's conditional sentence and the user screen is updated will be described. FIG. 13 shows a flowchart showing this operation. As described above, since the operator is informed that the operator screen has been updated by e-mail, the operator first sends the URL data of the initial screen to the search server A. The URL data is accepted by the search server A (s201), and the initial screen 400 is transmitted to the operator computer B (s202). The operator transmits the password to the search server A by inputting the password in the password input area 402 from the initial screen 400 and selecting the send button 402b. In the search server, this password is accepted by the authentication code accepting unit 109 (s203), and after being converted into URL data, an operator screen 700 having this password as a file name is extracted from the HP data storage unit 102 and transmitted. (S204).

On the operator screen 700, as shown in the figure, the keyword, the conditional sentence, and the deadline entered by the user in the response information input area are displayed. Therefore, the operator reads and operates the conditional sentence. If it is determined that the home page that is present corresponds to this conditional sentence, the corresponding information check box 703
Select d. On the other hand, if it does not correspond to the conditional statement, it is not necessary to do anything. When sending a message to a conditional sentence, the message is input to the message input area 703e. After that, when the relevant information check box 703d is checked by selecting the send button 704, the password of the user screen, the password of the operator screen, and the expiration date are provided as relevant information to the search server A. If the date data is transmitted and a message is input, this message data is also transmitted. In the search server A, the relevant information is accepted by the relevant information accepting unit, and the message is accepted by the message accepting unit 116 (s20).
5).

When these pieces of information are accepted, the date data indicating the deadline of the corresponding information is compared with the current date (s
206), if the date represented by the date data does not exceed the current date, the home page information is extracted based on the received corresponding information, and the user HP generation unit 113 updates the user screen 900 (s207). On the other hand, if the deadline has passed, nothing is done. User screen 900
Is updated, the response count information 904 is displayed as shown in FIG.
Is added, a response homepage display area 905 is added, and a message is displayed in the homepage title 905a and the message display area 905b in which a link to the homepage operated by the operator who responded is set. With the above, the operation from the response of the operator to the updating of the user screen is temporarily ended. Actually, the above operation is performed every time many operators access the operator screen.

As described above, in the home page search system according to the present embodiment, the searcher does not narrow down the home pages from the huge amount of search results, but the operators of individual home pages narrow down the search results. Therefore, the labor of the searcher is shared. In addition, even if the number of homepages extracted from keywords is huge, there are as many operators as there are operators, and operators are familiar with the contents of homepages, so when searchers check the contents of homepages. Compared to, the total amount of labor seen as a whole will be certainly reduced.

In the above embodiment, the user computer sends the search conditions and the like to the search server, the search server sends the search conditions and the like to the operator computer, and the operator computer sends the relevant information and the like. Although the search results are all sent from the search server to the user computer via the home page, they may be sent by push-type sending means such as electronic mail. In this case, the transmission of the search result from the search computer to the user computer will be performed after a lapse of time.

Further, in the above embodiment, the user separately inputs the conditional sentence and the keyword. However, by inputting only the conditional sentence, the keyword is extracted from the conditional sentence by the search server cutting out a word. You may do it. It goes without saying that the keyword search can use complicated conditional expressions such as AND search and OR search. Furthermore, in the above-mentioned embodiment, the content of the search condition is confirmed when the search condition is input and transmitted, but the search condition may be redone. For example, a button is provided to show the intention to finalize the search conditions so that the number of homepages extracted by the search conditions can be checked and the search conditions can be input again, and until this button is selected It is possible to adopt a method such that the search condition can be input again and again.

Then, in the above embodiment, the user screen should be deleted under certain conditions, such as deleting after a certain period of time has passed after the deadline has passed, or deleting after the user has browsed the user screen after the deadline has passed. You can also Further, the operator screen may be deleted under a certain condition such as deleting a conditional sentence whose response deadline has expired. Further, although the above embodiment is a search system for homepages on the Internet, it may be a system in which a computer of a person who knows the contents of a data file and a computer of a person who searches the data file are connected by a server. Anything can be applied. For example, in groupware used in a company, even when searching for a necessary data file, a conditional statement is sent to the computer of the employee who provided it for each data file obtained from the search results, and the corresponding information is displayed. By receiving it, it is possible to apply such as narrowing down data files.

[0040]

From the above description, the present invention has the following effects. In the inventions according to claims 1 and 5, after the data files are narrowed down by the search condition presented by the searcher, the administrator who manages these data files further narrows down the search condition and narrows down. Since the results are sent to the searcher, the administrator of each data file will share the effort to find the necessary one among the data files narrowed down by the search conditions, greatly reducing the effort of the searcher. You can In the inventions according to claims 2 and 6, the extraction of the data file is performed depending on whether or not the keyword is included, and the judgment of the administrator is performed by the conditional statement. Therefore, the first extraction of the data file includes the keyword. Whether or not it is possible, and the administrator can concretely judge the complicated contents by the conditional sentence.

The invention according to claims 3 and 7 prompts the administrator to respond by a fixed time limit, and the searcher can specify the time limit for obtaining the search result.
It can be expected that the search results to which most managers respond will be obtained within a certain period of time. Further, since the processing period in the data search server is limited, the load on the data search server can be reduced. In the inventions according to claims 4 and 8, since the specific intention of the administrator such as in what point the data files searched by the message data match, the message is transmitted to the searcher. The convenience when the searcher finally finds the necessary data file is improved, and the burden on the searcher can be reduced.
