  Next, a processing procedure when link information confirmation processing is executed using the above-described system will be described with reference to FIGS. Here, user browsing processing (FIG. 5), link check processing (FIG. 6), and recheck processing (FIG. 7) are executed.

(User browsing process)
First, the user browsing process will be described with reference to FIG. Here, the browser program of the user terminal 10 is activated and an access request is transmitted to the library information management server 20. In this case, the control unit 21 of the library information management server 20 executes user support processing (step S1-1). Specifically, the user support processing unit 211 of the control unit 21 transmits top page screen data to the user terminal 10.

  A menu screen for using the library is displayed on the browser of the display of the user terminal 10 that has received the top page screen data. On this menu screen, a selection button for a database to be normally searched is displayed. Here, a selection button for collection search (OPAC: Online Public Access Catalog) is displayed.

Then, by using the collection search selection button, a search screen for books and magazines is displayed on the user terminal 10 and a desired book or magazine can be searched. When a desired keyword is input on this search screen and the search execution button is selected, the user terminal 10 transmits a search request including data related to the input keyword to the library information management server 20.

  In this case, the user support processing unit 211 of the control unit 21 of the library information management server 20 performs a search process using the received keyword. Here, the catalog data storage unit 22 identifies the catalog record 220 including the received keyword. Then, list data including link data for accessing each specified catalog record 220 is generated. This list data includes information on items and bibliographies of each material. Then, list screen data including list list data is generated. Then, the user support processing unit 211 transmits this list screen data to the user terminal 10.

  The list screen is displayed on the browser of the display of the user terminal 10 that has received the list screen data. When a desired material is selected, the user terminal 10 transmits detailed display request data to the library information management server 20 using the link data of the selected material.

  In this case, the user support processing unit 211 of the control unit 21 of the library information management server 20 extracts the requested list record 220 in the list data storage unit 22 and transmits the detailed screen data to the user terminal 10. Here, when a URL is recorded as link information in the catalog record 220, an electronic journal link button is embedded in the detailed screen data so that the URL can be selected.

  And the control part 21 of the library information management server 20 performs a display data acquisition process (step S1-2). Specifically, when the electronic journal link button is selected on the detailed screen displayed on the browser of the user terminal 10, the user terminal 10 transmits a link request to this URL. This link request is made by relaying the user support processing means 211 of the control unit 21 of the library information management server 20. That is, the user support processing unit 211 that has received the link request from the user terminal 10 transmits display request data to this URL using the library information management server 20 as a transmission source. Thereby, the control part 21 of the library information management server 20 acquires the response data with respect to this display request data via the internet.

  The control unit 21 of the library information management server 20 that has acquired the response data via the Internet executes error identification processing (step S1-3). Specifically, the access monitoring unit 213 of the control unit 21 analyzes the received response data and acquires a message included in the response data. Then, this message is compared with the judgment condition recorded in the error identification data storage unit 23. For example, when a message indicating that the target page of the display request data cannot be detected (for example, “404 Not Found”) is included, it is determined that the link is broken.

  If a message matching the determination condition recorded in the error identification data storage unit 23 is not included (in the case of “NO” in step S1-4), it is determined that the link is not broken, and the library information management server 20 The control unit 21 performs normal display processing (step S1-5). Specifically, the user support processing unit 211 transfers display data acquired from the web server to the user terminal 10 via the Internet. In this case, data for displaying a selection button (error notification icon) for notifying when there is an abnormality in the display data is included. The user terminal 10 that has received the display data displays this data on the display.

Next, the control unit 21 of the library information management server 20 executes an error notification standby process from the user (step S1-6). If no error notification is received from the user and there is no problem (“NO” in step S1-6), the normal processing is terminated.

  On the other hand, when there is an abnormality in the display data, the user selects an error notification icon displayed on the display. In this case, the user terminal 10 transmits an error notification to the library information management server 20. When an error notification is received from the user terminal 10 (in the case of “YES” in step S1-6), the control unit 21 of the library information management server 20 executes an error recording process (step S1-7). This error recording process is also executed when the access monitoring means 213 determines that the link is broken (in the case of “YES” in step S1-4). Specifically, the access monitoring unit 213 acquires current time data from a system timer in the control unit 21. Then, a log record 240 is generated in which the current time, the URL related to the display request data, and the error code are recorded in the date / time field, the URL field, and the error code field, respectively, and the log record 240 is recorded. The error code specified by the access monitoring unit 213 is recorded in this error code field. Further, when an error notification icon is used in the user terminal 10, an error code for specifying "user abnormality notification" in the error code field and data for specifying the content of the received display data (for example, Source code). Furthermore, a code for specifying “error detection (first time)” is recorded in the response processing result field.

  The control unit 21 of the library information management server 20 executes an error display process (step S1-8). Here, the access monitoring unit 213 transmits error message data specified based on the corresponding processing code recorded in the error identification data storage unit 23 to the user terminal 10. For example, in the case of “404 Not Found”, a message such as “Currently not accessible. Library staff will respond, please use other documents.” Is displayed on the display of the user terminal 10. Thereby, a user browsing process is complete | finished.

(Link check process)
Next, the link check process will be described with reference to FIG. This process is executed periodically (for example, at a fixed time in the time zone when the user terminal 10 is not used at night) based on a schedule table recorded in advance in the library information management server 20. In this schedule table, data relating to the management code range of the electronic journal to be checked is recorded with respect to the processing start date and time.

  First, the control unit 21 of the library information management server 20 executes an extraction process of an electronic journal to be checked (step S2-1). Specifically, the link confirmation processing unit 212 of the control unit 21 specifies the electronic journal to be checked in the inventory data storage unit 22. In the present embodiment, a predetermined number of catalog records 220 recorded in advance in the schedule table are specified, and the catalog records 220 relating to the electronic journal are specified using the type club.

  Next, the control unit 21 of the library information management server 20 executes URL acquisition processing (step S2-2). Specifically, the link confirmation processing unit 212 of the control unit 21 acquires the URL included in the inventory record 220. When a plurality of URLs are recorded in the catalog record 220, all URLs are acquired.

  And the control part 21 of the library information management server 20 performs a display data acquisition process (step S2-3). The link confirmation processing means 212 of the control unit 21 attempts to access the web server via the Internet using this URL. Specifically, display request data is transmitted to the web server specified by this URL. Then, response data is acquired via the Internet.

  Next, the control part 21 of the library information management server 20 performs an error identification process (step S2-4). This processing is executed by the link confirmation processing means 212 of the control unit 21 in the same manner as Step 1-3 based on the response data.

  The control unit 21 of the library information management server 20 executes a link break determination process (step S2-5). This process is executed in the same manner as in step 1-4. If it is determined that the link is broken (“YES” in step S2-5), the controller 21 of the library information management server 20 executes an error recording process (step S2-6). In this case, as in step S1-7, the access monitoring unit 213 of the control unit 21 generates a log record 240 and records it in the log data storage unit 24.

  On the other hand, if a message matching the determination condition recorded in the error identification data storage unit 23 is not included (in the case of “NO” in step S2-5), this error recording process is skipped.

  And the control part 21 of the library information management server 20 performs an unchecked object confirmation process (step S2-7). Specifically, the link confirmation processing unit 212 of the control unit 21 confirms an electronic journal that has not yet been subjected to display data acquisition processing in the check target extracted in step S2-1.

  When the unchecked target remains (in the case of “YES” in step S2-7), the control unit 21 of the library information management server 20 specifies the next check target (step S2-8). Then, the link check process of the check target inventory record 220 is executed. On the other hand, if there is no unchecked target and the display data acquisition process is completed for all the check target inventory records 220 (NO in step S2-7), the link check process is terminated. .

(Recheck process)
Next, the recheck process will be described with reference to FIG. In this process, a check process is performed again for the inventory record 220 once having detected an error after a predetermined time interval. Specifically, the processing is executed for a record in which “first time” is recorded in the corresponding processing result of the log record 240 recorded in the log data storage unit 24.

  Here, the control unit 21 of the library information management server 20 executes standby processing for a predetermined time (step S3-1). Specifically, the recheck processing unit 214 of the control unit 21 specifies the recording date / time of the “first” log record 240 and waits for the elapse of a predetermined time from this date / time (“NO” in step S3-1). ).

  When a predetermined time has elapsed from the date and time of the log record 240 relating to the first error detection (in the case of “YES” in step S3-1), the control unit 21 of the library information management server 20 executes a URL acquisition process (step S3-2). In this case, the recheck processing unit 214 of the control unit 21 acquires the URL recorded in the log record 240.

  And the control part 21 of the library information management server 20 performs a display data acquisition process (step S3-3). And the control part 21 of the library information management server 20 performs an error identification process (step S3-4). Here, the recheck processing unit 214 of the control unit 21 executes the same as in steps SS1-2 and S1-3.

When an error code specifying “user error notification” is recorded in the error code field, the content of the display data received for the first time (for example, source code) is acquired and received for the second time. Compared with the contents of the display data, it is determined whether there is a change in the display contents. Then, when there is no change in the display content, it is determined that the link is broken.

  If it is determined that the link is broken (“YES” in step S3-5), the control unit 21 of the library information management server 20 executes an error recording process (step S3-6). Specifically, when the access monitoring unit 213 detects a second error, it outputs an error signal to the recheck processing unit 214, and the recheck processing unit 214 outputs an “error detection (second time)” code. Record in the log record 240.

  And the control part 21 of the library information management server 20 performs a notification process (step S3-7). Specifically, the recheck processing unit 214 of the control unit 21 acquires the detection result of the access monitoring unit 213 and transmits an error notification to the staff terminal 15. Here, an error notification is transmitted using an electronic mail that can be used in the staff terminal 15. This error notification includes data regarding the log record 240. In this case, library staff will check for broken links and take action as necessary.

  On the other hand, if it is determined that the link is not broken (“NO” in step S3-5), the control unit 21 of the library information management server 20 executes error recovery processing (step S3-6). In this case, the recheck processing unit 214 records the “error recovery” code in the log record 240 and ends the process.

As described above, according to the present embodiment, the following effects can be obtained.
In the above embodiment, this link request is made via the control unit 21 of the library information management server 20. And the control part 21 of the library information management server 20 acquires the response data with respect to this display request data via the internet. In this case, the access monitoring unit 213 of the control unit 21 analyzes the received response data and acquires a message included in the response data. Then, this message is compared with the judgment condition recorded in the error identification data storage unit 23. Thereby, a broken link can be detected and maintenance can be performed efficiently. As a result, useless searches can be suppressed and search accuracy can be improved.

  In the above embodiment, when the electronic journal link button is selected on the detailed screen displayed on the browser of the user terminal 10, the user terminal 10 transmits a link request to this URL. This link request is made by relaying the user support processing means 211 of the control unit 21 of the library information management server 20. As a result, the control unit 21 of the library information management server 20 acquires response data for the display request data via the Internet. And the control part 21 of the library information management server 20 which acquired response data via the internet performs an error identification process (step S1-3). If it is determined that the link is broken, the access monitoring means 213 executes error recording processing. As a result, it is possible to identify a URL having a problem even in a search using the user terminal 10 and perform maintenance of the URL based on the log recording.

  In the above embodiment, the user support processing unit 211 transfers display data acquired from the web server to the user terminal 10 via the Internet. In this case, data for displaying a selection button (error notification icon) for notifying when there is an abnormality in the display data is included. Thereby, it is possible to identify a URL having a problem based on recognition by the user.

In the above embodiment, the control unit 21 of the library information management server 20 performs processing for extracting electronic journals to be checked (step S2-1) and executes URL acquisition processing (step S2-2). Then, the control unit 21 of the library information management server 20 executes display data acquisition processing using this URL (step S2-3), and executes error identification processing (step S2-4). If it is determined that the link is broken, the control unit 21 of the library information management server 20 executes an error recording process (step S2-6). Thereby, maintenance of a huge amount of link data can be executed.

  In the above embodiment, when a predetermined time has elapsed from the date and time of the log record 240 relating to the first error detection, the control unit 21 of the library information management server 20 executes URL acquisition processing (step S3-2). In this case, the recheck processing unit 214 of the control unit 21 acquires the URL recorded in the log record 240. And the control part 21 of the library information management server 20 performs a display data acquisition process (step S3-3), and performs an error identification process (step S3-4). When the controller 21 of the library information management server 20 determines that the link is broken, the controller 21 of the library information management server 20 executes an error recording process (step S3-6) and a notification process (step S3-6). S3-7). As a result, the notification process is performed except for a temporary error, so that the burden on the library staff can be reduced.

In addition, you may change the said embodiment into the following aspects.
In the above embodiment, the present invention is applied to the confirmation process for broken links in the URL of the electronic journal recorded in the catalog data storage unit 22 of the library information management server 20, but the check target is not limited to this. For example, the present invention can be applied to a URL recorded as a bookmark such as “favorite” stored in a browser of a computer terminal.

  In the above embodiment, when the access monitoring unit 213 detects the second error, it outputs an error signal to the recheck processing unit 214, and the recheck processing unit 214 displays the “error detection (second time)” code. Is recorded in the log record 240. And the control part 21 of the library information management server 20 performs a notification process (step S3-7). Specifically, the recheck processing unit 214 of the control unit 21 transmits an error notification to the staff terminal 15. Transmission of the error notification to the staff terminal 15 is not limited to the second error detection, and may be performed for the first time or the third time. By notifying at the first error detection, it is possible to quickly cope with a broken link. On the other hand, by notifying at the third error detection, it is possible to deal with the staff after confirming that the link is broken, and to reduce the burden on the staff.

  In the above embodiment, an error notification is transmitted to the staff terminal 15 in the second error detection. The timing for transmitting the error notification to the staff terminal 15 does not have to be fixed, and can be changed according to the situation. For example, it may be changed based on the number of URLs for error detection in one link check process. In this case, the library information management server 20 stores a data table that records the number of times of error detection that defines the timing for transmitting an error notification for the number of URLs for error detection. Then, after the link check process, the number of URLs for error detection is counted, and the timing for transmitting an error notification from the data table is determined. As a result, when the number of detected errors is large, an error notification can be transmitted after reliably verifying the broken link.

In the above embodiment, when an error notification is received from the user terminal 10 (in the case of “YES” in step S1-6), the control unit 21 of the library information management server 20 executes an error recording process (step S1). -7). In addition to this, status data may be recorded in the catalog record 220 recorded in the catalog data storage unit 22. In this case, a status field is provided in the catalog record 220, and a flag indicating a broken link is recorded. Then, in the list screen data provided to the user terminal 10, an inaccessible message is added for this document. This flag is deleted when access is restored by recheck processing or staff maintenance. Thereby, useless access can be suppressed.

  In the above embodiment, the link check process is periodically executed based on the schedule table recorded in advance in the library information management server 20. In this schedule table, data related to the management code range of the book to be checked is recorded with respect to the processing start date and time. Instead, the last access date and time may be recorded for the management code, and a predetermined number of inventory records 220 may be acquired for the management code with the oldest last access date and the link check process may be executed. . If the last access date is new, the possibility of a broken link is low. For this reason, it is possible to improve the efficiency of the link check process by giving priority to a link that has a relatively high possibility of being broken.
