JP4030992B2 - LINK ERROR DETECTION DEVICE, LINK ERROR DETECTION METHOD, AND PROGRAM THEREOF - Google Patents

Description

  The present invention relates to a link error detection apparatus, a link error detection method, and a program therefor, and particularly detects link errors existing in a plurality of hypertexts.

  In recent years, individuals, companies, various organizations, and the like have frequently released Web sites in which documents in a hypertext format are gathered on the Internet. This hypertext has a feature that a link can be established in the middle of a document to a specific position of the same document or another document having contents related to the description contents in the vicinity thereof. However, there is a possibility that the hypertext includes a link error such that a document or text does not exist at the link destination or a link to a different location is made.

Software known as an island detector is known as one of the techniques for detecting such link errors (for example, see Non-Patent Document 1 below). This solitary island detector detects unreferenced files and files with broken links for hierarchical files on a personal computer and graphically displays them on the screen of the personal computer of the user, that is, the website administrator. indicate.

As another means for detecting a link error, that is, inconsistency, WebTreands (registered trademark) -related software is known (for example, see Non-Patent Document 2 below). This WebTreands (registered trademark) -related software has a function of detecting a broken link on a website along with an access analysis function for the website, and creates a report visible to the user. This broken link detection function can detect any site on the Internet other than the user's personal computer.

On the other hand, some techniques for creating / editing Web site content can detect broken links. For example, software called Interwoven TeamSite (registered trademark) has a function of collectively detecting inconsistencies of links for each content even when the content of the website is created and managed by a plurality of administrators (for example, Non-patent document 3 below).
TeamSite, [online], [Search August 25, 2003], Internet <URL: http://www.interwoven.co.jp/>

  With the above-mentioned solitary island detector and WebTrends (registered trademark) -related software, it is possible for each administrator to detect link errors in hypertext independently. However, there is a problem that link errors cannot be centrally detected for a plurality of hypertexts, and therefore link errors cannot be detected efficiently.

  On the other hand, with the above-described software called Interwoven TeamSite (registered trademark), it is possible for a plurality of administrators to detect a link error for a plurality of hypertexts as a whole. In this case, all target files must be under the control of Interwoven TeamSite (registered trademark). Therefore, there is a problem that Interwoven TeamSite (registered trademark) cannot be applied to a site that is generally integrated in recent years, such as a subsidiary, a branch, a service, a product classification, etc., in which a plurality of Web sites are integrated in a loose relationship.

  Further, the above software has a problem that scheduling for setting a date and time for detecting a link error in consideration of a network load cannot be performed.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a link error detection device and the like capable of detecting a link error in consideration of a network load.

(First embodiment)
FIG. 1 is a block diagram showing an example of a hardware structure of a link error detection apparatus applied to the embodiment of the present invention. FIG. 2 is a block diagram showing an example of the configuration of the link error detection apparatus applied to the present embodiment.

  As shown in FIG. 1, this link error detecting device includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Mmeory) 13, a hard disk drive (HDD) 14, and a communication. A device 15 and a display device 17 are provided.

  The CPU 11 reads the program stored in the ROM 13 to the RAM 12 and executes it, thereby controlling the entire link error detection device. CPU11 performs the process mentioned later.

  The RAM 12 is composed of, for example, a dynamic RAM. The RAM 12 is used as a memory for securing a program execution area, a work area, and the like. In the program execution area, a program executed by the CPU 11 is appropriately read from the ROM 13 and stored. The work area stores data necessary for the CPU 11 to execute the program.

  The ROM 13 stores a control program executed by the CPU 11 and the like. The ROM 13 stores various programs for managing hypertext.

  The HDD 14 stores various data corresponding to each program for managing hypertext. The stored data is read out to the RAM 12 by the CPU 11.

  The communication device 15 is connected to the network 20 and transmits / receives hypertext data via the Internet, an intranet, or the like.

  The input device 16 includes a keyboard, a mouse, and the like, and inputs various instruction information.

  The display device 17 is composed of, for example, an LCD, and displays various character information and image information generated by the CPU.

Next, with reference to FIG. 2, the structure of the link error detection apparatus of this Embodiment is demonstrated.
The link error detection apparatus includes a content collection unit 100, a content storage unit 101, an inconsistency detection unit 102, an inconsistency table 103, a schedule management unit 104, a schedule table 105, an administrator table 106, and a notification unit. 107 and a repair acceptance unit 108. The processing in the content collection unit 100, the inconsistency detection unit 102, the schedule management unit 104, the notification unit 107, and the repair reception unit 108 is physically executed by the CPU 11.

  The content collection unit 100 collects a plurality of hypertexts and stores them in the content storage unit 101. The content collection unit 100 is physically realized by the CPU 11 executing a content collection program loaded in the RAM 12 and collecting hypertext of a website from the communication device 15 via the Internet or an intranet. . The content collection unit 100 stores the collected hypertext in the content storage unit 101. Here, the content collection unit 100 can acquire hypertext from a website based on software called wget (http://www.gnu.org/software/wget/wget.html).

The content storage unit 101 stores a plurality of hypertexts collected by the content collection unit 100. The content storage unit 101 physically corresponds to the HDD 14.
FIG. 3 is a schematic diagram illustrating an example of hypertext of a Web site stored by the content storage unit 101. As illustrated, the content storage unit 101 stores a URL (Uniform Resource Locator) 301 and text 302 in tabular form for each hypertext.

  The inconsistency detection unit 102 detects link errors (including link destination errors and broken links) existing in the hypertext stored in the content storage unit 101. In the inconsistency detection unit 102, physically, the CPU 11 loads the inconsistency detection program into the RAM 12, executes the inconsistency detection program, and stores the hypertext in which the link error is detected in the HDD 14. It is realized by.

  Here, a method for detecting an error in a link existing in the hypertext by the inconsistency detection unit 102 will be described. For example, a hypertext in HTML (Hyper Text Markup Language) format, which is the content of a Web site, has a descriptive term indicating the presence of link information such as an <a> tag. The inconsistency detection unit 102 extracts a link expression such as an <a> tag from the hypertext 302 stored in the content storage unit 101. Then, the inconsistency detection unit 102 refers to the hypertext stored in the content storage unit 101 and determines whether there is a link destination corresponding to the link information indicated in the extracted link expression. The inconsistency detection unit 102 can detect inconsistencies based on the software called the solitary island detector described in the background section above.

The inconsistency table 103 is a table for storing link errors detected by the inconsistency detection unit 102. This inconsistency table 103 physically corresponds to a part of the HDD 14.
FIG. 4 is a schematic diagram showing an example of an inconsistency table created for hypertext of a specific Web site. The inconsistency table 103 includes a link source 401 that indicates the URL of the link source, an absolute position that indicates from which position in the hypertext of the URL of the link source 401, and a link expression of the link source 401. A link destination 403 indicating the URL of the link destination to be specified is stored. Here, the URL of the link destination 403 does not always exist. The link expression that specifies the URL of the link destination 403 that does not actually exist is called a dead link. In this case as well, it is determined that this is a kind of link error.

  The inconsistency table 103 is created by an error table creation unit (not shown). This error table creation unit is physically realized by the CPU 11 executing the error table creation program loaded in the RAM 12.

  FIG. 5 is a schematic diagram illustrating an example of the configuration of the schedule management unit 104 and the schedule table 105. The schedule table 105 stores a list of scheduled execution times 501 of link error detection processing. The schedule table 105 physically corresponds to a part of the HDD 14.

The schedule management unit 104 includes a schedule execution unit 502, a clock 503, and a schedule setting unit 504. The schedule execution unit 502 refers to the schedule table 105 and activates the content collection unit 100, the inconsistency detection unit 102, and the notification unit 107 at the scheduled execution time 501 registered in the schedule table 105, and Link error detection processing such as collection and link error detection is performed. The schedule execution unit 502 is physically realized by the CPU 11 loading a schedule execution program into the RAM 12 and executing the schedule execution program. That is, the CPU 11 refers to the list of scheduled execution times stored in the schedule table 105 in the HDD 14 and executes error detection processing at the corresponding scheduled execution time.
The schedule execution unit 502 monitors the clock 503, and if the current time (date / time / day of the week) matches the scheduled execution time 501 stored in the schedule table 105, the content collection unit 100, the inconsistency detection unit 102, and The notification unit 107 is activated. If the current time does not coincide with the scheduled execution time 501, monitoring of the clock 503 is continued. The schedule execution unit 502 repeats such processing at regular intervals. Note that the schedule execution unit 502 may activate only the content collection unit 100 and the inconsistency detection unit 102.

  The schedule setting unit 504 adds the input scheduled execution time 501 to the schedule table 105, or changes or deletes the already registered scheduled execution time 501 based on the instructed information. The schedule setting unit 504 is realized by the CPU 11 executing a schedule setting program loaded into the RAM 12. The CPU 11 refers to the schedule table 105 of the HDD 14 based on information for adding, changing, and deleting the scheduled execution time of the schedule input from the input device 16, and adds, changes, and deletes the scheduled execution time. The scheduled execution time added is stored in the schedule table 105.

  The administrator table 106 stores a list of hypertext administrators, that is, information indicating which hypertext belongs to which administrator. This administrator table 106 physically corresponds to a part of the HDD 14.

FIG. 6 is a schematic diagram illustrating an example of the administrator table 106 for HTML-formatted hypertext that is the content of a Web site. An administrator table creation unit (not shown) determines the manager to which the hypertext 601 belongs by the so-called longest matching collation of hypertext, and stores the hypertext 601 and the administrator's name 602 in the manager table 106.
This administrator table creation unit is physically realized by the CPU 11 executing an administrator table creation program loaded into the RAM 12. As a result, a plurality of hypertexts and information specifying the manager are associated and stored in the manager table 106.

  The notification unit 107 determines, for each inconsistency in the inconsistency table 103 (for each link error), a hypertext administrator having an inconsistency with reference to the administrator table 106. The notification unit 107 notifies the administrator who is determined to be a hypertext administrator who has inconsistency that the inconsistency exists. The notification unit 107 is physically realized by the CPU 11 executing a notification program for a hypertext administrator loaded in the RAM 12. The CPU 11 refers to the inconsistency table 103 and the administrator table 106 of the HDD 14 and transmits, for example, an e-mail from the communication device 15 to the text administrator 602 in which the link error is detected, and the presence of inconsistency exists. To be notified. In this case, it is assumed that each administrator's e-mail address is stored in association with the administrator 602 in the administrator table 106 described above.

  The repair reception unit 108 updates the inconsistency table 103 by deleting information related to the inconsistency from the inconsistency table 103 based on the information that the inconsistency from the hypertext administrator has been corrected. The repair acceptance unit 108 is physically realized by the CPU 11 executing a repair acceptance program loaded into the RAM 12. The CPU 11 confirms with the mail server whether there is an e-mail that has arrived via the communication device 15, and refers to the inconsistency table 103 of the HDD 14 to delete information relating to the error of the corresponding link. When a repair notification is received by e-mail from each hypertext administrator, the repair receiving unit 108 checks with the mail server whether there is an e-mail that has arrived at regular intervals. If the e-mail has arrived, the repair receiving unit 108 reads the mail contents, identifies the line including the corresponding link error in the inconsistency table 103, and deletes the line.

  The operation of the link error detection apparatus according to the embodiment of the present invention will be described below with reference to FIGS. FIG. 7 is a flowchart for explaining link error detection processing. FIG. 8 is a flowchart for explaining the repair acceptance process.

  First, the CPU 11 refers to the clock 503 and acquires the current time (step S701).

  The CPU 11 refers to the scheduled execution time 501 of the schedule table 105 and determines whether or not the current time acquired in step S701 matches the scheduled execution time 501 (step S702).

  When the CPU 11 determines that the current time coincides with the scheduled execution time 501 and is time to perform link error detection processing, the CPU 11 accesses a Web site registered in advance via the communication device 15. The CPU 11 collects hypertext in the accessed website and stores it in the HDD 14 (step S703). On the other hand, if it is determined that the current time is not the scheduled execution time 501 (step S702: No), the CPU 11 returns to step S701 and executes step S701.

  When all the hypertexts in the site are collected in step S703 and stored in the HDD 14, the CPU 11 detects a link error in the stored hypertext. For the detected link error, the CPU 11 identifies the link source (hypertext URL), the absolute position of the hypertext in which the link information is described, and the link destination, and stores them in the inconsistency table 103 (step S704). ).

  When link errors are detected for all hypertexts in step S704 and the detected link errors are registered (stored) in the inconsistency table 103, the CPU 11 stores one inconsistency (link link) stored in the inconsistency table 103. Error). The CPU 11 confirms with the mail server whether or not the hypertext administrator including the link error has been notified of inconsistency (step S705) (confirmation of unconfirmed inconsistency).

  If the CPU 11 determines that the inconsistency is not notified (step S706; No), the hypertext manager including the inconsistency is determined with reference to the administrator table 106 (step S707). On the other hand, if it is determined that it does not correspond to the unreported mismatch (step S706; Yes), the CPU 11 ends the link error detection process.

  When the hypertext administrator is determined (step S707; Yes), the CPU 11 creates and transmits an e-mail notifying the link error to the e-mail address of the corresponding administrator (step S708). This e-mail includes information (URL) for specifying the hypertext, the position (absolute position) in the hypertext of the link in which the link error has occurred, and link destination information.

  When the administrator determined in step S707 is notified of the link error, the CPU 11 returns to step S705 and executes steps from step S705 to step S708.

  On the other hand, when the hypertext manager cannot be determined (step S707; No), the CPU 11 returns to step S705 and executes steps from step S705 to step S707.

  The hypertext administrator corrects the link error based on the e-mail from the notification unit 107. When the administrator corrects the link error, the administrator creates an e-mail notifying the error in a predetermined format. This e-mail includes a code indicating that the e-mail is to be notified of repair, the URL of the link source hypertext, the absolute position of the repaired link, and the information (URL) of the link destination after the repair, The address of the destination mailbox is a predetermined specific address.

  Next, the repair acceptance process shown in FIG. 8 will be described. Here, a case will be described as an example where a hypertext administrator makes a repaired contact by e-mail.

  The CPU 11 checks the mailbox to which the specific address of the mail server is assigned (step S801).

  Next, the CPU 11 determines the presence / absence of mail in the mailbox (step S802).

  If it is determined that a mail exists (step S802; Yes), the CPU 11 sequentially takes out the e-mails from the mail box, and interprets the contents included in the mail according to the format described above (step S803). On the other hand, if it is determined that there is no mail (step S802; No), the CPU 11 returns to step S801 and executes step S801. In this case, step S801 may be performed again after a certain time.

  The CPU 11 identifies an inconsistency in the inconsistency table 103 corresponding to the link error notified to be repaired based on the interpretation result of the electronic mail (step S804).

  Then, the CPU 11 deletes information regarding the identified link error from the inconsistency table 103 (step S805). Thereby, the repair acceptance process ends.

  As described above, in the present embodiment, it is possible to detect link errors by concentrating on a plurality of hypertexts managed by a plurality of managers at a predetermined time. In addition, the hypertext administrator in which a link error is detected can repair only the link error, when convenient, or depending on the severity of the link error, independently of other administrators. Can give you the opportunity to. Therefore, the quality can be improved at a unified level as a plurality of hypertexts as a whole.

(Second Embodiment)
FIG. 9 is a block diagram showing an example of the configuration of a link error detection apparatus applied to this embodiment. Here, in the link error detection apparatus of the present embodiment, the components other than the difference content collection unit 201 that is the second content collection unit and the difference mismatch detection unit 202 that is the second link error detection unit are as follows. Since it is the same as that described in the first embodiment, the description of the first embodiment is cited, and differences from the first embodiment will be described.

  The difference content collection unit 201 periodically refers to the inconsistency table 103 and acquires information on the link source 401 and the link destination 403 of the hypertext in which the inconsistency is detected. The differential content collection unit 201 collects hypertext from the Internet, an intranet, a file system, or the like based on the information of the link source 401 and the link destination 403. The difference content collection unit 201 overwrites the collected hypertext on the corresponding hypertext already stored in the content storage unit 101. The differential content collection unit 201 is physically realized by the CPU 11 executing the differential content collection program loaded into the RAM 12. The CPU 11 refers to the inconsistency table 103 of the HDD 14 and collects hypertexts in which inconsistencies are detected from websites accessed by the communication device 15 via the Internet or an intranet. Here, the differential content collection unit 201 can acquire hypertext from a website based on software called wget (http://www.gnu.org/software/wget/wget.html).

  The difference inconsistency detection unit 202 refers to the inconsistency table 103 and acquires information on the link source 401 and the link destination 403 of the hypertext in which the inconsistency is detected. The difference mismatch detection unit 202 refers to the corresponding hypertext in the content storage unit 101 based on the acquired information, and determines whether or not there is actually a link error. If there is no link error, the difference mismatch detection unit 202 deletes the information of the corresponding row from the mismatch table 103. The difference mismatch detection unit 202 is physically realized by the CPU 11 executing a difference mismatch detection program loaded in the RAM 12.

  The difference inconsistency detection unit 202 refers to the inconsistency table 103 and extracts a link expression such as an <a> tag from the hypertext text 302 stored in the content storage unit 101. Next, the difference mismatch detection unit 202 determines whether there is a link destination corresponding to the extracted link expression with reference to the hypertext stored in the content storage unit 101. As described above, the mismatch detection unit 102 can detect mismatches based on software called an island detector. When the difference mismatch detection unit 202 determines that there is no link error, the difference mismatch detection unit 202 deletes the row including the corresponding link information from the mismatch table 103.

  By adopting such a configuration, when the administrator corrects the link error but fails to contact the administrator, or when the administrator corrects the link error before receiving the notification of the link error, etc. In the error detection apparatus according to (1), information on the repaired link can be deleted from the inconsistency table 103.

  Hereinafter, the operation of the link error detection apparatus applied to this embodiment will be described with reference to FIG. FIG. 10 is a flowchart for explaining the link error detection processing according to this embodiment.

  First, the CPU 11 refers to the clock 503 and acquires the current time (step S901).

  The CPU 11 refers to the scheduled execution time 501 of the schedule table 105 and determines whether or not the current time acquired in step S901 matches the scheduled execution time (step S902). If it is determined that the current time does not coincide with the scheduled execution time 501 (step S902; No), the CPU 11 returns to step S901 and executes step S901.

  If the CPU 11 determines that the current time matches the scheduled execution time 501 (step S902; Yes), the CPU 11 extracts the link source 401 information and link destination information of the hypertext in which inconsistency is detected, and based on these information Corresponding hypertext is collected from the Internet, an intranet, or a file system, and overwritten on the corresponding hypertext in the content storage unit 101 (step S903).

  The CPU 11 extracts the information of the link source 401 and the link destination 403 of the hypertext in which inconsistency is detected from the inconsistency table 103, and refers to the content storage unit 101 on the basis of the information to cope with it. It is determined whether or not there is an actual link error in the hypertext. If there is no link error, the CPU 11 deletes the row including the corresponding link information from the inconsistency table 103 (step S904). Thereby, the link error detection process ends.

  As described above, in the present embodiment, it is possible to detect a link error in a concentrated manner at a predetermined time for a plurality of hypertexts managed by a plurality of managers. In addition, the hypertext administrator who detected the link error has repaired the link error, but even if he / she neglected to report the repair, the hypertext with the link error was selectively re-inspected. Therefore, the quality of the entire hypertext can be managed efficiently.

(Third embodiment)
FIG. 11 is a block diagram showing an example of the configuration of a link error detection apparatus applied to this embodiment. In this embodiment, the link error detection apparatus includes a schedule adjustment unit 510 instead of the schedule setting unit 504 and the schedule table 105 of the schedule management unit 104 in the first embodiment. That is, the CPU 11 refers to the storage device 530 of the schedule adjustment unit and executes error detection processing at the corresponding scheduled execution date and time. Since the other constituent elements are the same as those described in the first embodiment, the description of the first embodiment will be cited and differences from the first embodiment will be described.

  The schedule adjustment unit 510 includes a data processing device 520, a storage device 530, an input device 16, and an output device 18.

  The output device 18 includes a display device 17 and a printing device.

  The data processing device 520 includes a preliminary test unit 521 and a reservation setting unit 522.

  The pre-test unit 521 refers to the clock 503, collects hypertext from a website designated via the Internet or an intranet, and stores the hypertext in the content storage unit 101 at the designated pre-test execution scheduled time. The pre-test unit 521 detects a link error for the hypertext stored in the content storage unit 101 and stores the detected link error in the inconsistency table 103. When the storage of the detected link error is completed, the pre-test unit 521 refers to the clock 503, calculates the time required for the error detection process, and stores it in the work time storage unit 531.

  The reservation setting means 522 refers to the scheduled execution date and time of the link error detection process stored in the schedule storage unit 532, and the maximum parallel execution number indicating the number of accesses to the website registered in advance is It is determined whether the load limit of the network 20 has been exceeded. Here, whether or not the load limit of the network is exceeded is determined based on the time required for the error detection processing by the pre-test unit 521, particularly the time required for collecting the hypertext. The reservation setting unit 522 calculates the scheduled execution date and time when it is determined to be executable, and calculates the earliest date and time when the maximum number of parallel executions is allowed based on the load limit of the network when it cannot be executed. To do. The reservation setting unit 522 stores the scheduled execution date or calculated date in the schedule storage unit 532 together with the time required for the link error detection process in the preliminary test as the scheduled execution date.

The storage device 530 includes a work time storage unit 531 and a schedule storage unit 532.
The work time storage unit 531 stores the time required for the link error detection process in the preliminary test by the preliminary test unit 521.
The schedule storage unit 532 stores the scheduled execution date and time of the link error detection process and the time required for the link error detection process by the pre-test unit 521 for each Web site.

  Next, the operation of the link error detection apparatus applied to this embodiment will be described with reference to FIG. FIG. 12 is a flowchart for explaining the schedule setting process according to the present embodiment.

  First, the URL of the Web site input via the input device 16, information on the depth of the site indicating the location of the hypertext (for example, the number of routes in the root directory), and the scheduled execution date and time of the preliminary test are the preliminary test. It is supplied to the means 521 (step S1001).

  The pre-test unit 521 accesses the website designated in step S1001 via the communication device 15, collects the designated hypertext in the website, and stores it in the HDD 14 (step S1002).

  When all the instructed hypertexts in the site are collected in step S1002 and stored in the HDD 14, the pre-test unit 521 detects a link error in the stored hypertext. The prior test means 521 specifies the link source (hypertext URL), the hypertext absolute position where the link information is described, and the link destination for the detected link error, and stores them in the inconsistency table 103. (Step S1003).

  The prior test means 521 refers to the clock 503, calculates the time required for execution of the link error detection processing, that is, the steps from S1002 to S1003, and calculates the time required for the link error detection processing as a work time storage unit. 531 is stored (step S1004).

  The reservation setting unit 522 refers to the scheduled execution date and time of the link error detection process stored in the schedule storage unit 532 and the preliminary test time stored in the work time storage unit 531 (step S1005). In the reservation setting unit 522, the maximum number of parallel executions indicating the number to be accessed in parallel with a pre-registered website based on the preliminary test time exceeds the load limit of the network 20 at the scheduled execution date and time referred to. It is determined whether there is any (step S1006). If the reservation setting unit 522 determines that execution is possible (step S1006; Yes), the scheduled execution date and time are stored in the schedule storage unit 532 together with the time required for the link error detection processing in the preliminary test (step S1006; Yes). S1008).

  If it is determined that execution is not possible (step S1006; No), the reservation setting unit 522 calculates the earliest date and time when the maximum number of parallel executions is allowed based on the network load limit (step S1007). The reservation setting unit 522 stores the calculated date and time as the scheduled execution date and time in the schedule storage unit 532 together with the time required for the link error detection process in the preliminary test (step S1008).

  The reservation setting unit 522 displays the scheduled execution date and time stored in the schedule storage unit 532 on the display device 17 (step S1009). Thereby, the schedule setting process ends.

  As described above, in the present embodiment, the pre-test unit 521 performs link error detection processing in advance for the specified hypertext of a specific Web site. The reservation setting unit 522 calculates the date and time when the link error detection process can be performed in consideration of the network load based on the above-described preliminary test result, and stores the calculated date and time in the schedule storage unit 532. Therefore, the administrator can rationally determine the date and time for link error detection.
