Then, a content with added tag transmission part transmits the content to which the tag is added to the client terminal.

Description

  The present invention relates to a mediation server that analyzes the access status of a Web site, and an access analysis method and program using the mediation server.

  There are three types of access analysis tools that analyze website access status. The three types are classified into a server log type, a packet capture type, and a tag type (Web beacon type) according to the data acquisition method required for analysis. The server log type and packet capture type do not require modification to the web content to be measured, but the server logs and communication packets of the accessed data are processed and access analysis is performed, so it is not suitable for analysis of large-scale sites. And there is a problem that data necessary for analysis is not available.

  On the other hand, the tag type requires correction to the Web content to be measured, but the most accurate data can be obtained. The specific difference between the server log type and the packet capture type is that you can not only know the page transition status for each visitor accurately, but also obtain the past visit history of any visitor and the list of visited pages. It is to become.

  The tag type is already commercially available as disclosed in Non-Patent Document 1, for example. In addition, a method of installing an intermediary server between communication paths between a Web server and a Web client (browser) is also well known. The intermediary server automatically embeds a program to be transmitted to a server that aggregates information necessary for analysis.

  The method will be briefly described with reference to FIG. 14 (FIG. 14). A WWW (WWW: World Wide Web) relay server 900 as an intermediary server includes an HTML analysis unit 101, a browsing time measurement unit 102, a script generation unit 103, a browsing position measurement unit 104, a browsing information DB 105, a positional information 106, and an HTTP control unit. 107. The WWW relay server 900 plays a role of acquiring a Web page from each WWW server 112 that provides a Web page in response to a request from a Web browser executed by the client 111 and transferring it to the client 111.

  The HTML analysis unit 101 analyzes the Web page requested by the client 111 and extracts an HTML source at a designated position. The browsing time measuring unit 102 measures the browsing time of the Web page based on the browsing information update process from the client 111. The script generation unit 103 embeds a program such as a Java (registered trademark) script so that the client 111 can automatically update browsing information. The browsing position measurement unit 104 measures the position information in the Web page based on the browsing information update process from the client 111.

  The browsing information DB 105 manages the browsing information by adding identification information to the Web page browsed by the viewer and the browsing time. The position information DB 106 manages the position information of the Web page viewed by the viewer with an identifier. The HTTP control unit 107 controls HTTP communication with the client 111 and HTTP communication with the WWW server 112.

  Conventional mediation servers can only collect basic information such as browsing time, browsing position, and browsing count uniformly. That is, only predetermined information managed by the browsing information DB 105 and the position information DB 106 is collected even if the purpose and characteristics of the Web site change. However, the types of data to be collected and analyzed for each Web site are generally different, and conventional mediation servers can collect only insufficient information in that respect.

  In addition, when there are a plurality of analysis target websites or a website with a large number of accesses, the amount of log data used for access analysis increases and the load on the measurement server that performs the measurement increases. Therefore, there is a problem that when the number of browsing web pages increases, the load on the measurement server also increases.

  The present invention has been made in view of such a problem. An intermediary server capable of collecting sufficient access information and suppressing an increase in the load on a measurement server, and the intermediary server The purpose is to provide an access analysis method and program.

  An intermediary server according to the present invention is an intermediary server set between a plurality of Web servers and client terminals, and includes a browsing request receiving unit, a request transfer unit, a content receiving unit, a tag storage unit, and a tag adding unit. And a tagged content transmission unit. The browsing request receiving unit receives a browsing request from the client terminal. The request transfer unit transfers the browsing request to the Web server. The content receiving unit receives content from the Web server. The tag storage unit stores a tag defined for each access target. The tag adding unit adds the tag to the content. The tagged content transmission unit transmits the content with the tag to the client terminal.

  In addition, another mediation server of the present invention further includes a tag embedding table, a browse request count / tag addition count storage unit, and an analysis result correction unit in addition to the configuration of the mediation server described above. The tag embedding table defines the ratio of tag embedding operations for each access target. The browsing request number / tag addition number storage unit stores the browsing request number and the tag addition number in which the tag is embedded. The analysis result correction unit transmits the corrected measurement result obtained by correcting the measurement result from the measurement server using the number of browsing requests and the number of tag additions to the client terminal.

  Since the intermediary server of the present invention adds tags defined for each access target to the content received from the Web server and transmits them to the client terminal, various tags can be defined that are automatically embedded in the Web page. . Therefore, it is possible to provide information necessary and sufficient for access analysis according to the access target.

  In addition, another intermediary server of the present invention embeds tags according to the ratio of tag embedding operations for each access target, and corrects the measurement result from the measurement server according to the ratio, so that the measurement server obtains correct access information. Overload can be avoided.

Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals are given to the same components in a plurality of drawings, and the description will not be repeated.

  FIG. 1 shows a functional configuration example of the mediation server 100 of the present invention and a configuration example of a Web mediation server system 1000 using the mediation server 100. The operation flow is shown in FIG. The mediation server 100 is a server set via the network 113 between the plurality of Web servers 114 and the client terminal 116. The measurement server 115 measures access information between the client terminal 11 and the Web server 114.

  The mediation server 100 includes a browsing request reception unit 10, a request transfer unit 11, a content reception unit 12, a tag addition unit 13, a tag storage unit 14, and a tagged content transmission unit 15. The functions of the respective units are realized by a predetermined program being read into a computer constituted by, for example, a ROM, a RAM, and a CPU, and the CPU executing the program.

  The browsing request receiving unit 10 receives a browsing request from the client terminal 116 (step S10). The request transfer unit 11 transfers the browsing request from the client terminal 116 to the web server 114 (step S11). The content receiving unit 12 receives content from the Web server 114 (step S12). The tag storage unit 14 stores a tag defined for each access target. The tag addition unit 13 reads the tag stored in the tag storage unit 14 and adds it to the content received from the Web server 114 (step S13). The tagged content transmission unit 15 transmits the content with the tag added to the client terminal 116 (step S15).

  Here, the tag memorize | stored in the tag memory | storage part 14 is demonstrated. The tag is literally a tag for access analysis, and the tag specifies the measurement server 115 that analyzes the access information of the client terminal 116.

  FIG. 3 shows an example of tags stored in the tag storage unit 14. A tag is defined for each access target. Each access target is each Web server 114 and each URL (Uniform Resource Locator) to be accessed. For example, the tag corresponding to the URL of Web server A to be accessed is “src =” xxx.xxx.xxx?c=123456&p = ”> </ SCRIPT>. This tag is for the operator of Web server A Tag (access analyst of Web server A) is defined, where “xxx.xxx.xxx” represents the address of the measurement server 115, and what follows is information that the client terminal 116 transmits to the measurement server 115. “P =” indicates an example in which an instruction for automatically assigning a page ID is given. The page ID is information given to each page to be accessed, and the number of accesses can be analyzed for each page ID. In general, the page ID can be assigned by the access analyst, or can be automatically numbered.

  “Flag1 = 1234” after? In the tag corresponding to the URL of the second Web server B to be accessed is an instruction to transmit the URL immediately before the transition to the Web server B to the measurement server 115. In the third tag, by setting “p = abcd”, the page IDs of multiple pages below http://www.ntt.com/business are all abcd, and access analysis is performed as a single page. An example is shown. The fourth tag shows an example in which the Web server operating company is different from the first to third operating companies. As described above, the type of information transmitted from the client terminal 116 to the measurement server 115 can be changed depending on the access target.

  For example, in the case of a personal site composed of a plurality of pages (URLs) such as a blog site, it is possible to change access analysis settings for each personal site. For some blog sites, only the number of visitors to the site can be counted, and for other blog sites, page transitions within the site can be analyzed in detail, and the type of information required for access analysis can be changed for each access target. .

  The client terminal 116 analyzes the tag added to the content and transmits information necessary for access analysis to the measurement server 115. This operation itself is the same as the conventional tag type, but the mediation server 100 of the present invention is characterized in that the tag can be changed for each access target as described above.

  FIG. 4 shows an operation sequence diagram of the Web mediation server system 1000 shown in FIG. The client terminal 116 transmits a request for requesting access to the Web server 114 to the mediation server 100 (step S1). The request transfer unit 11 of the mediation server 100 transfers the browsing request to the Web server 114 (step S11). The web server 114 transmits the content to the mediation server 100 in response to the browsing request (step S12). The tag addition unit 13 of the mediation server 100 reads the tag associated with the Web server 114 from the tag storage unit 14 and adds it to the received content (step S13). Then, the tagged content transmission unit 15 of the mediation server 100 transmits the content with the tag added to the client terminal 116 (step S15).

  The client terminal 116 analyzes the tag and requests an access analysis program (generally a Java (registered trademark) script) from the measurement server designated by the tag (step S2). The measurement server 115 transmits an access analysis program to the client terminal 116 (step S3). The client terminal 116 executes a program for access analysis and transmits information necessary for access analysis to the measurement server 115 (step S4). The measurement server 115 receives information necessary for access analysis, and transmits a 1 × 1 dot size transparent gif file as a response to the client terminal 116 (step S5).

  The measurement server 115 analyzes the data transmitted from the user, PV (page display number: page view), CV (conversion), number of visitors, browsing time, page transition in the site, entry path to the measurement target page , Analyze viewer behavior such as withdrawal information. The analysis result of the measurement server 115 can be viewed from the client terminal 116 (step S6).

  As described above, the mediation server 100 according to the present invention adds the tag defined for each access target to the content received from the Web server and transmits it to the client terminal 116, so that the tag is automatically embedded in the Web page. It is possible to provide information necessary and sufficient for access analysis according to the access target.

  Although FIG. 3 shows an example in which one tag is defined for each URL, the tag adding unit 13 can embed a tag according to the content. For example, when there is a link destination address in the source of the Web page, a tag for notifying the measurement server that the link destination has been changed may be added.

  FIG. 5 shows an example of a web page source. FIG. 5A shows the source of a Web page to which no tag is added. “<a href=www.ntt.com>” represents the link destination address, but if this link destination is an unmeasured site, the page transition information is lost at the moment the user clicks the link destination. End up.

  In order to prevent this, for example, a tag “onclick =” page Tracker._link (this.ref); return false; ”>” is added after the link destination address as shown in FIG. It ’s fine. The tag to be added with such a condition is configured such that the tag addition unit 13 embeds a tag specified when, for example, the condition is Web server A and the link destination is a site not to be measured. You can add it to the content.

  By embedding tags according to such conditions, it is possible to further specify the conditions for access analysis.

  Conventionally, authentication technology (Single Sign On, etc.) that centralizes user authentication to multiple servers is known (reference: http://www.atmarkit.co.jp/icd/root/88/ 56025488.html). A mediation server 200 of the present invention that can be applied to an access analysis to a Web server that performs such user authentication in a concentrated manner will be described as a second embodiment.

  FIG. 6 shows a functional configuration example of the mediation server 200 and a functional configuration example of the Web mediation server system 2000 using the mediation server 200. The mediation server 200 is set between the client terminal 116 and the authentication server 119 connected to the plurality of Web servers A, B 117 and 118. The operation flow is shown in FIG. In the Web mediation server system 2000, the authentication server 119 has a function of holding authentication information (user ID) and a client session (access) management function. The authentication server 119 can uniquely associate authentication information for each session (access). In addition to the authentication server 119, a function for holding authentication information may be provided in another server (not shown) connected to the authentication server 119.

  The mediation server 200 includes an authentication result determination unit 21 and an authentication result tag embedding unit 22 in addition to the functional configuration of the mediation server 100. The authentication server communication unit 20 is provided instead of the request transfer unit 11 of the mediation server 100. Other functional units are the same as those of the mediation server 100.

The authentication server transmission unit 20 transmits a browsing request from the client terminal 116 and authentication information necessary for client authentication to the authentication server 119 (step S20). The authentication result determination unit 21 determines the authentication result from the authentication server 119 (step S21). If the authentication result is authentication information, that is, the result of authorizing the client, the authentication result tag embedding unit 22 replaces the portion marked “user ID” in the tag with the actual user ID (step S22). If the authentication result does not authorize the client, the authentication result tag embedding unit 22 does nothing.
Table 1 shows an example of a tag that the authentication result tag embedding unit 22 replaces the user ID.

  When the authentication result determination unit 21 authorizes the access from the client terminal 116, the authentication result tag embedding unit 22 replaces the portion indicated by (user ID) shown in Table 1 with an actual user ID. The second tag in Table 1 shows an example of replacing a user ID in combination with a user ID and a pre-defined page ID corresponding to the user ID. This second example is convenient when collecting page information in the case of a personal site composed of a plurality of pages (URLs) such as a blog site.

  As described above, the mediation server 200 can embed tags according to the user even when combined with the authentication server. Therefore, even in this case, it is possible to specify in detail the conditions for access analysis for each user.

  The above-described mediation servers 100 and 200 can effectively define various tags to be automatically embedded in a Web page, and can provide information necessary and sufficient for access analysis. However, on the other hand, there is a concern that the addition on the measurement server side is increased. Therefore, as a third embodiment, an intermediary server 300 of the present invention in which the functions of the intermediary servers 100 and 200 are devised to reduce the load on the measurement server side will be described.

  FIG. 8 shows a functional configuration example of the mediation server 300. The operation flow is shown in FIG. The mediation server 300 is different from the mediation servers 100 and 200 in that the mediation server 300 further includes a tag embedding table 30, a browsing request count / tag addition count storage section 31, and an analysis result correction section 32.

  The tag embedding table 30 is a table that defines the ratio of tag embedding operations for each access target. The ratio of the tag embedding operation is, for example, that a 100% tag is added to the access to the Web server A and a tag is added to a response of 50% of the access to the Web server B. An example of the tag embedding table 30 of Table 2 is shown.

  The tag addition unit 13 ′ refers to the ratio defined in the tag embedding table 30 for each access target, performs lottery at the ratio, and adds a tag to the content (step S13 ′). If no tag is added, the content is transferred without modification. Lottery means adding tags to content at this predetermined ratio. The tagged content transmitting unit 15 ′ transmits the content with the tag added to the client terminal 116 at the ratio (step S15 ′).

  The browsing request number / tag addition number storage unit 31 stores the browsing request number and the tag addition number in which the tag is embedded (step S31). Table 3 shows an example of the browsing request number m and the tag addition number n stored in the browsing request number / tag addition number storage unit 31.

  The analysis result correction unit 32 receives, for example, the access number c of the measurement result from the measurement server 115, reads the browsing request number m and the tag addition number n stored in the browsing request number / tag addition number storage unit 31, and accesses them. The number of previous visitors G is corrected to G = c × m ÷ n and transmitted to the client terminal 116 (step S32).

  If the tag is not embedded in the content corresponding to the browsing request, the browsing request is not subject to access analysis, but the access information is corrected to a correct value by the analysis result correcting unit 32.

  As described above, the mediation server 300 has the effect of providing correct access information and reducing the load on the measurement server 115.

  Note that access information such as the order of pages accessed by visitors to the site cannot be accurately measured even by the mediation server 300. Also, it is impossible to know past browsing information of an arbitrary visitor. This is because the measurement target is randomly divided for each access. Therefore, the mediation server 400 that solves this problem will be described next.

  The functions of the tag addition unit 13 ′, the tagged content transmission unit 15 ′, the tag embedding table 30, the browsing request number / tag addition number storage unit 31, and the analysis result correction unit 32 may be mounted on another server. .

  FIG. 10 shows a functional configuration example of the mediation server 400. The operation flow is shown in FIG. The mediation server 400 differs from the above-described mediation servers in that a tag embedded storage unit 40 is provided.

Whether the tag embedding storage unit 40 has added a tag to the first browsing request from the client terminal 116 that has transmitted the content with the tag added at a rate corresponding to the rate for each access target defined in the tag embedding table 30. Is stored (step S40). The tag embedding storage unit 40 resets itself at intervals of, for example, 30 minutes. The first browsing request after being reset becomes the first browsing request.
Table 4 illustrates information stored in the tag embedding storage unit 40.

  Table 4 is an example in which information indicating whether or not a tag is added to the browsing request from the client terminal is stored in association with the IP address of the client terminal. Further, it may be stored in combination with the access date and time.

  When a tag is added to the previous browsing request with reference to the tag embedding storage unit 40, the tag adding unit 13 ″ adds a tag to the content corresponding to the current browsing request. The tag is added to the previous browsing request. If this is not done, the tag is not added.By operating in this way, it is possible to reduce the number of tags to be embedded while accurately measuring the browsing history of any visitor. It is possible to reduce the load on the measurement server while ensuring the performance.

  Note that information indicating whether or not a tag has been added may be provided on the client terminal side using a cookie (hereinafter referred to as cookie) instead of the tag embedded storage unit 40 of the mediation server 400 (reference document “HTTP (Web) Protocol session maintenance method http://fenics.fujitsu.com/products/ipcom/catalog/data/1/6.html ”). A cookie is information stored in a Web browser of a client terminal, and URL information of an access destination is stored. As shown in Table 5, the client terminal side may have information on whether or not a tag has been added.

  The tag embedding operation using Cookie is as follows. Since the holding time is set for the cookie, the tag addition unit 13 ″ embeds the tag by lottery according to the ratio defined in the tag embedding table 30 in response to a new browsing request within the holding time.

  Whether or not the tag is embedded is stored in a cookie. For a browsing request to the same access destination within the holding time, the cookie embedding information is confirmed, and a tag is added if a tag was added at the previous browsing request. If no tag is added at the time of the previous browsing request, no tag is added. For the access that has expired, it is drawn again as a new access.

  Since the mediation servers 300 and 400 perform the tag embedding operation at a predetermined ratio, there is a problem that the mediation servers 300 and 400 cannot adapt to the sequentially changing access situation. For example, access to related sites when a new advertisement is executed generally changes greatly before and after the advertisement, but the number of accesses may exceed the expectation. In addition, when the effect is temporary, the load on the measurement server may be drastically reduced. An intermediary server 500 that can adaptively cope with such a situation will be described as a fifth embodiment.

  FIG. 12 shows a functional configuration example of the mediation server 500. The operation flow is shown in FIG. The mediation server 500 differs from the mediation server 400 in that it includes a measurement server load status monitoring unit 50 and a tag embedding ratio changing unit 51.

The measurement server load status monitoring unit 50 periodically monitors the load status of the measurement server 115 (step S50). “Periodic” may be every unit time (for example, 30 minutes, 1 hour, etc.) or at the time of browsing request. The tag embedding rate changing unit 51 changes the rate defined in the tag embedding table according to the load status of the measurement server 115 monitored by the measurement server load status monitoring unit 50 (step S51). The request number / tag addition number storage unit 31 ′ periodically stores the number of embedded tags and the number of accesses based on the ratio changed by the tag embedding ratio changing unit 51 (step S31 ′).
Table 6 shows an example of “ratio” changed by the tag embedding ratio changing unit 51.

  In Table 6, for example, when the number of accesses within 24 hours of the access destination “www.aaa.co.jp” exceeds 100,000 times, an example is shown in which the ratio of embedding tags in the content is limited to 20%. . In addition, since the load on the measurement server decreases as the number of recent accesses decreases, the ratio of access destinations “www.aaa.co.jp” and “www.bbb.co.jp” is both 90%. Moreover, the ratio at the time of concentration of access may be changed according to the access destination so that the ratio of “www.bbb.co.jp” is 10%.

  Table 6 shows an example in which the tag embedding ratio is varied according to the number of accesses, that is, for the purpose of avoiding load concentration on the measurement server, but information necessary for access analysis in combination with other conditions. Can also be collected with sharpness. Table 7 shows an example where the date and time and region are marked.

  In this way, by changing the ratio for each time zone, region, etc., it is possible to perform access analysis with narrowed points.

As described above, the intermediary server of the present invention adds a tag defined for each access target to the content received from the Web server and transmits it to the client terminal, so various tags can be automatically embedded in the Web page. Can be defined. At the same time, accurate information necessary for access analysis can be obtained while reducing the load on the measurement server.
When the processing means in each device described above is realized by a computer, the processing contents of functions that each device should have are described by a program. Then, by executing this program on the computer, the processing means in each apparatus is realized on the computer.

  The program describing the processing contents can be recorded on a computer-readable recording medium. As the computer-readable recording medium, for example, any recording medium such as a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory may be used. Specifically, for example, as a magnetic recording device, a hard disk device, a flexible disk, a magnetic tape or the like, and as an optical disk, a DVD (Digital Versatile Disc), a DVD-RAM (Random Access Memory), a CD-ROM (Compact Disc Read Only) Memory), CD-R (Recordable) / RW (ReWritable), etc., magneto-optical recording media, MO (Magneto Optical disc), etc., semiconductor memory, EEP-ROM (Electronically Erasable and Programmable-Read Only Memory), etc. Can be used.

  This program is distributed by selling, transferring, or lending a portable recording medium such as a DVD or CD-ROM in which the program is recorded. Further, the program may be distributed by storing the program in a recording device of a server computer and transferring the program from the server computer to another computer via a network.

  Each means may be configured by executing a predetermined program on a computer, or at least a part of these processing contents may be realized by hardware.
