Description

  The present invention relates to a system and method for evaluating a website that provides a plurality of services.

  In recent years, various services have been provided via the Internet, and in addition to existing WEB sites, personal-to-individual or individual-to-group community-type WEB sites such as SNS (Social Networking Service) have been developed. The revenue of this kind of WEB site is mainly advertising revenue such as banner advertisements displayed on the WEB page and advertisements added to e-mails. The operator of the WEB site can increase the popularity of the WEB site and obtain more advertisements by increasing the number of visitors to the WEB site operated by the WEB site.

  Here, when the operator etc. presents the degree of popularity of the own WEB site to the advertiser, the number of browsing, the number of browsing (visitors), or the repeat rate (frequency that the same viewer browses again) It is known to present the trends of viewers.

As a method of grasping the trend of the WEB site, a method of analyzing the transition history of the WEB page based on the access history of the viewer (for example, Patent Document 1), or the password entered when logging in to the WEB site is used. What analyzes a trend (for example, patent document 2) is known.
JP 2002-123516 A Japanese Patent Laying-Open No. 2005-284884

  However, in the above conventional example, since the trend of the viewer is analyzed based on the access history of the WEB site, it can only be analyzed in a predetermined counting period such as daily or monthly. There was a problem that the trend could not be grasped in real time.

  In addition, on WEB sites such as the above SNS, the preferences and interests of the viewers and users change from moment to moment. Therefore, if the current trends of the viewers are not grasped in real time, the WEB that responds to the needs of the viewers. Providing a site is difficult. In the conventional example described above, there is a problem that it is necessary to change a program, a script, and the like in order to change an object for analyzing a viewer's trend, and it cannot be easily and quickly performed.

  In particular, on WEB sites such as the above-mentioned SNS, user preferences and interests change from moment to moment, so the target of aggregation is not only the number of views but also the trends of search keywords, the types of services used, etc. Trend indicators also change from moment to moment. In the above-described conventional example, only fixed items such as the number of viewers and WEB page transition history are analyzed, and thus there is a problem that it is difficult to evaluate the trend of the viewer for any item.

  Therefore, the present invention has been made in view of the above problems, and aims to grasp the trend of the WEB site viewer in real time, and also to grasp the trend of the viewer for any item. To do.

  The present invention relates to access of a client by a second server that generates a log when the first server providing a service to the client receives an access from the client and receives the log from the first server. A mining method for performing evaluation, wherein a log is sequentially stored in the storage unit repeatedly in a procedure including a procedure for receiving a log from the first server and a predetermined number of storage units for storing the received log. A procedure; a procedure for receiving an evaluation command including an evaluation condition and an evaluation item from a second client; a procedure for generating an agent for evaluating the log of the buffer based on the evaluation command; and starting the generated agent A procedure for the agent to extract a log including information matching the evaluation condition from the buffer; A procedure of performing an evaluation corresponding to the evaluation item on the log extracted by the agent, generating an evaluation result, a procedure of adding the generated evaluation result to the position of the extracted log on the buffer, and the second Transmitting the evaluation result to the client.

  The procedure for generating the agent sets the evaluation condition and the evaluation item included in the evaluation command to the agent to be generated, generates a plurality of agents according to the number of the evaluation commands, The procedure for starting the agent starts the agent.

  Therefore, according to the present invention, the logs accessed by the clients in a buffer that can store up to a predetermined number are sequentially stored, and the logs on the buffer are evaluated, so that the trend of the clients that accessed the first server can be grasped in real time. It becomes possible to do. In addition, the second client can grasp the client's trend for any item without changing the script or program as in the conventional example, and the client's preferences change from moment to moment. Can be grasped in real time.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing an example of a computer system to which the present invention is applied according to the first embodiment.

  In FIG. 1, a gateway device 1 connected to a network 13 such as the Internet includes a load balancer and a firewall. The gateway device 1 is connected to a server computer group including a plurality of application servers 2 that provide a predetermined service for access from the network 13. These server computer groups constitute a WEB site that provides a predetermined service. Although not shown, each computer (server) includes a CPU, a memory, and a storage device. In the following description, an example of providing an SNS composed of a plurality of communities (a group of users who exchange information) on the WEB site is shown. In the SNS, message transmission / reception, bulletin board input / output, image data and text data are shown. Includes services such as publishing.

  Connected to the network 13 are a WEB client 11 for accessing a WEB site and a WEB client 12. The WEB client 11 is a computer operated by a general user (user) who uses the SNS of the WEB site, and includes a browser. The WEB client 12 is a computer operated by a special user such as an SNS (Social Networking Service) community administrator (community owner) or a WEB site administrator, and has a different access authority from a general user (member or visitor). A special user.

  The plurality of application servers 2 connected to the gateway device 1 includes services such as message transmission / reception, bulletin board input / output, image data and text data disclosure, and the plurality of application servers 2 provide SNS. The application server 2 includes a WEB server that communicates with the WEB clients 11 and 12 using HTTP. The service provided by the WEB site is not limited to the SNS, and may include provision of a WEB page, moving image data, music data, and the like.

  The plurality of application servers 2 are respectively connected to the internal network 8 of the WEB site. In this internal network 8, a database server 3 that stores data used in services provided by various server computer application servers 2 in an application database 30, and a log generated by the application server 2 is stored in a user operation log database 40. Log server 4, a sequential mining server 6 that performs an evaluation described later based on the log, an evaluation result server 7 that stores an evaluation result generated by the sequential mining server 6 in the valuation database 70, and each server computer in the WEB site Are synchronized with each other. Note that the evaluation performed by the sequential mining server 6 includes counting or analyzing the operation information (operation event) of the client 11 included in the log.

  Next, FIG. 2 is a block diagram showing the main part of each server computer and the flow of data. When the application server 2 receives an access from the WEB client 11, the application server 2 includes a log generation unit 21 that executes a predetermined service and indicates the access contents of the WEB client 11. The log generated by the log generation unit 21 includes, for example, information such as the identifier of the WEB client 11, the name of the executed service, and the accessed URL, and the history of operations performed by the user of the WEB client 11 is generated as a log. . The identifier of the WEB client 11 may be an identifier of the WEB client 11 that can uniquely identify the accessed WEB client 11 or the user, such as an IP address or a user ID in the case of a membership SNS.

  Next, a time stamp of the current time is given to the log generated by the log generation unit 21 by the time stamp giving unit 22. Logs to which time stamps are assigned are input to the queue 23 and sequentially written to the user operation log server 4.

  As described above, the plurality of application servers 2 respond to the access from the WEB client 11, record the user operation contents based on the access contents in a log, add a time stamp to the log, and store it in the user operation log server 4. I will do it.

  The user operation log server 4 writes the log received from each application server 2 to the user operation log database 40 and sequentially transmits this log to the mining server 6 as an event. That is, when a write to the user operation log database 40 occurs, the user operation log server 4 sequentially transmits a log to the mining server 6 using this write as a trigger. The user operation log server 4 can read the user operation history in an appropriate order by sorting the logs stored based on the time stamp.

  The sequential mining server 6 functions as an event monitor server, and handles logs from the user operation log server 4 as user operation events. Note that a plurality of sequential mining servers 6 may be provided. In this case, the user operation log server 4 transmits logs to all the sequential mining servers 6.

  The sequential mining server 6 performs a preset evaluation on the log received from the user operation log server 4. The sequential mining server 6 receives an evaluation command received from the community owner of the WEB client 12 and generates a mining agent 63, a black board 62 for storing a log received from the user operation log server 4, and a black It consists of a mining agent 63 that extracts logs (operation events) input to the board 62 and performs predetermined evaluation. The black board 62 is configured to reflect a change with time, and is specifically realized as a first-in first-out (FIFO) type ring buffer.

  The agent management unit 61 includes an item (evaluation item) for evaluating a user operation event included in the log from a special user having a predetermined authority, such as a community owner of the WEB client 12, and what conditions for this item. An evaluation command including an evaluation condition as to whether or not to perform analysis is accepted. Then, the agent management unit 61 generates a mining agent 63 for evaluating the user operation event included in the log based on the evaluation item and the evaluation condition, and activates the mining agent 63. The agent management unit 61 can generate a plurality of mining agents 63 and start them in parallel. For example, the agent management unit 61 can generate a plurality of mining agents 63 by receiving a plurality of evaluation commands from one WEB client 12. A plurality of mining agents 63 can be generated by receiving a plurality of evaluation commands from a plurality of WEB clients 12. When the number of mining agents 63 to be executed increases, a plurality of sequential mining servers 6 may be provided as shown in FIG.

  Evaluation items set by the WEB client 12 include the number of browsing, the number of browsing (visitors), or the repeat rate, the population in the community (number of members), the staying time of the user or visitors, the amount of data in the community, and the advertisement The number of browsing, the URL of the viewed advertisement, the type of service used, and the like. The evaluation conditions include the time point or period (currently, the past one day, etc.), URL, IP address, user ID, etc. for monitoring the evaluation item. For example, when the number of viewers of a certain community is evaluated, the number of viewers is set as the evaluation item, and the URL and time are set as the evaluation conditions. The agent management unit 61 may provide a predetermined interface and generate an evaluation command based on an input from the WEB client 12, or the WEB client 12 may generate an evaluation command including the evaluation items and the evaluation conditions. An evaluation command in a predetermined format may be transmitted, and the agent management unit 61 may receive this evaluation command.

  When the agent management unit 61 receives an evaluation command from the WEB client 12, the agent management unit 61 sets an evaluation item and an evaluation condition in a preset template or the like to generate the mining agent 63. For example, when the mining agent 63 is generated by a script using XML, the mining agent 63 is generated by setting an evaluation item and an evaluation condition at a predetermined position of the template. In this case, on the storage device (memory) of the mining server 6, the mining agent 63 that monitors the black board 62 and the middleware that executes the mining agent 63 are executed. Note that the mining agent 63 is not limited to a script, and may be generated as an object that monitors the blackboard 62 and executes a predetermined evaluation.

  The black board 62 is composed of a ring buffer divided into a plurality of slots on the memory of the mining server 6 and the like, and sequentially stores logs received from the user operation log server 4 in the slots. When the buffer becomes full (overflow state), the ring buffer discards the oldest log and overwrites the latest log. That is, only the latest log is always stored in the black board 62.

  The mining agent 63 analyzes the log on the black board 62 based on preset evaluation items and evaluation conditions. Then, when the evaluation for one log (event in the figure) is completed, the mining agent 63 generates an evaluation result. The mining agent 63 stores the generated evaluation result in the evaluation result server 7 and adds this evaluation result to the log on the black board 62. In other words, by adding the evaluation result to the log, the other mining agent 63 can evaluate the evaluation result performed on one evaluation item of one mining agent 63. Further, the mining agent 63 transmits the generated evaluation result to the community owner who has set the mining agent 63. The agent management unit 61 can set the contents of the evaluation command to the mining agent 63 and set the community owner's IP address and mail address, thereby transmitting the evaluation result from the mining agent 63 to the community owner in real time. .

  The black board 62 is set as a storage area that can be shared by a plurality of mining agents 63. The black board 62 is configured, for example, as shown in FIG. 3, and is set as a storage area having n slots. Each slot includes an area for storing a log, an area for storing a plurality of evaluation results, and an area for storing times (time stamps) sequentially received by the mining server 6.

  FIG. 4 is a flowchart illustrating an example of processing performed by the mining agent 63.

  First, in S1, the mining agent 63 searches the blackboard 62 and acquires the oldest unprocessed log. In S <b> 2, it is determined whether or not the acquired log includes information on an evaluation target (evaluation item, evaluation condition). If the information to be evaluated is included in the log, the process proceeds to S3, and if not included, the process proceeds to S5.

  In S3, an evaluation item is evaluated based on the acquired log information, and an evaluation result is generated. In S4, the generated evaluation result is written in the same slot as the acquired log. At this time, the evaluation result is transmitted to the evaluation result server 7 and stored in the valuation database 70. In S5, the position of the slot evaluated by the mining agent 63 is stored as processed, and the reception time of the log is also stored. As the slot position of the black board 62, a value such as a memory address or a serial number that can uniquely identify the storage position on the black board 62 may be used.

  The mining agent 63 can arbitrarily discard the contents of the slot. This is effective for realizing a filter operation that sifts information.

  By repeatedly executing the above processing, the mining agent 63 executes the sequential evaluation processing for all the logs (operation events) on the black board 62 in real time, and generates the current evaluation result. The user of the WEB client 12 (community owner or WEB site manager) can know the current trend of the WEB site viewers in real time by referring to the evaluation result.

  The mining agent 63 can suppress the information to be written in the slot by storing itself up to which slot of the black board 62 configured by the ring buffer.

  In addition, when a large number of new logs are received, the blackboard 62 may determine that an unprocessed log has been processed due to the characteristics of the ring buffer, or the order of logs to be processed may be reversed. is assumed. For this reason, when the sequential mining server 6 receives a log, it adds a reception time with sufficiently fine accuracy to each log.

  The mining agent 63 compares the reception time of the log (slot) stored as processed and the reception time stamped in the same slot. If the reception time is different, the blackboard 62 overflows. Can be determined.

  Through the above processing, the mining agent 63 can sequentially evaluate the logs received from the user operation log server 4 and output the evaluation results.

  In the WEB client 12, the community owner (special user) can appropriately read the evaluation result from the evaluation result server 7 and use the evaluation result. The evaluation result generated by the plurality of mining agents 63 includes an owner attribute assigned to each community owner in order to identify which special user has instructed the evaluation. By referring to the owner attribute, each community owner can identify whether or not the evaluation result is the commanded by the community owner.

  For example, when the community owner analyzes the number of visitors in the current community, the URL of the community to be evaluated and the current condition are sequentially transmitted from the WEB client 12 to the mining server 6.

  The sequential mining server 6 sets the number of visitors in the community as an evaluation item, and sets a value indicating the present and a designated URL as an evaluation condition. As shown in FIG. 4, the sequential mining server 6 analyzes all the logs on the blackboard 62, counts IP addresses or user IDs from the logs including the information to be evaluated, and eliminates duplicate values. An evaluation result is generated with the number of visitors as the number of visitors in the current community, and transmitted to the evaluation result server 7. Note that the mining agent 63 can set the value being tabulated in the evaluation result of each slot.

The mining agent 63 of the sequential mining server 6 generates the evaluation result, and then transmits the evaluation result to the WEB client 12 of the community owner who has set the mining agent 63. Also, the community owner of the WEB client 12 receives the evaluation result server 7 By accessing, the evaluation result of the mining agent 63 may be acquired in real time.

  When the evaluation target period is in the past, the mining agent 63 can acquire the evaluation target log from the log server 4 for the log that does not exist on the blackboard 62 and perform the evaluation. For example, when the size of the black board 62 is about several hours, if the evaluation condition is set to one day or the like, it is possible to request the user operation log server 4 for a log of an insufficient period. The size of the black board 62 may be set as appropriate depending on the scale of the WEB site and traffic. In addition, when evaluating the current community when the size (capacity) of the black board 62 is extremely large, the accuracy of the evaluation result is ensured by adding conditions such as the past several minutes from the current time as the evaluation conditions. can do.

  In the processing shown in FIG. 4, since the mining server 6 can execute a plurality of mining agents 63 in parallel, a certain mining agent 63 evaluates the population (the number of accesses) of the entire WEB site, and other mining agents. 63 evaluates the number of browsing advertisements in the WEB site, performs a plurality of evaluations simultaneously, and can evaluate a plurality of events in real time.

  Further, the agent management unit 61 can generate and start a plurality of mining agents 63 in response to instructions from a single or a plurality of community owners. For this reason, in addition to the administrator and owner of the WEB site, the community owner of the SNS can arbitrarily set a desired evaluation target.

  Further, when the number of browsing of a predetermined advertisement is sequentially evaluated by the mining server 6 as follows. When the WEB client 11 requests an advertisement in the WEB site, the application server 2 transmits the advertisement, and a log including the identifier (URL) of the transmitted advertisement and the identifier (IP address) of the WEB client 11 is sent. Generate. Then, the agent management unit 61 that has received the advertisement browsing number as an evaluation command from the WEB client 12 generates a mining agent 63 in which the advertisement identifier is set as the evaluation condition and the advertisement browsing number is set as the evaluation item. The mining agent 63 is activated.

  The mining agent 63 searches the log on the blackboard 62, extracts the identifier of the WEB client 11 from the log including the advertisement identifier, and adds the number of identifiers of the WEB client 11 (or the log including the advertisement identifier). )) As the number of advertisements viewed. Note that when evaluating the number of browsing advertisements, the number of browsing advertisements minus the number of duplicate identifiers of the WEB client 11 may be output as the number of browsing advertisements.

  In addition, when evaluating the number of browsing of a predetermined advertisement of each community that provides SNS, the WEB client 12 uses an identifier of the advertisement to be evaluated as an evaluation condition, and an evaluation command using the number of browsing of the advertisement for each community as an evaluation item. Are sequentially transmitted to the mining server 6. The agent management unit 61 that has received the evaluation command for the number of advertisements for each community from the WEB client 12 sets an advertisement identifier as an evaluation condition, and sets the number of advertisements for each community as an evaluation item. 63 is generated and activated.

  The mining agent 63 searches the log on the black board 62, extracts the identifier of the WEB client 11 from the log including the identifier of the advertisement, and totals the sum of the number of identifiers of the WEB client 11 as the number of browsing advertisements. . And based on the identifier of the WEB client 11, the browsing number of the advertisement for every community is output as an evaluation result. Note that the association between the identifier of the WEB client 11 and each community may be set in advance in a table storing the identifier of the WEB client 11 to which it belongs for each community identifier. Thereby, the WEB client 12 can evaluate the number of the WEB clients 11 that have browsed the existing advertisement in almost real time for each community by referring to the evaluation result from the mining server 6 or the evaluation result server 7 sequentially. It becomes.

  As described above, according to the first embodiment of the present invention, by evaluating the log (operation event) on the blackboard 62 configured by a ring buffer, the trend of the WEB site viewer can be grasped in real time. It becomes possible to do. In addition, according to the present invention, the WEB client 12 can grasp the trend of a viewer for any item without changing a script or a program, so that a viewer or an SNS member who changes from time to time can be obtained. It becomes possible to quickly configure the community and the WEB page according to the taste. Further, the mining agent 63 writes the evaluation result to the slot of the black board 62, so that when a plurality of mining agents 63 are activated, the other mining agent 63 calculates the evaluation result on the black board 62. By doing so, it becomes possible to perform more advanced evaluation.

  In the conventional example, an operator of a WEB site analyzes a visitor's trend based on a past access history, and the operator himself uses the trend of a visitor of the WEB site, It was common to present trends.

  On the other hand, in community-type services such as SNS, a plurality of communities are provided in the WEB site, and the community owners mainly provide information and the like. The community owner can increase the value (popularity) of the community by grasping the trends of the viewers or users (members) of the community established by the community owner.

  For this reason, by using the WEB client 12 by the community owner, it is possible to grasp in real time the evaluation information about the community launched by the community owner and the evaluation information of the entire WEB site. That is, the community owner can grasp the trend of the viewer managed by the community owner in real time by giving a desired evaluation command to the agent management unit 61.

Second Embodiment
FIG. 5 shows a second embodiment and shows an example in which a plurality of sequential mining servers 6 shown in the first embodiment are connected in series. Other configurations are the same as those of the first embodiment.

  In FIG. 5, the sequential mining server 6A stores the log received from the user operation log server 4 as an event in the blackboard 62, similar to the sequential mining server 6 shown in FIG. 3 of the first embodiment, and the mining agent In step 63, the evaluation result is output.

  The sequential mining server 6A transmits the calculated evaluation result to the sequential mining server 6B connected to the next stage. The sequential mining server 6B stores the received evaluation result as an event in the blackboard 62, and performs a predetermined evaluation by the mining agent 63. The mining agent 63 transmits the calculated second evaluation result to the valuation database 70 of the WEB client 12 or the evaluation result server 7.

  In this case, the sequential mining server 6B can further process and analyze the evaluation results obtained by the sequential mining server 6A. Since the analysis (or processing) based on the evaluation result is performed on the black board 62, the second evaluation result can be obtained in real time.

  For example, the sequential mining server 6A obtains the number of users who have subscribed to the SNS in real time, and sequentially transmits the evaluation results (aggregation results) to the mining server 6B. The sequential mining server 6B calculates and outputs the rate of increase / decrease (units / minute) per unit time from the received evaluation result (number of subscribed users).

  As described above, by performing the evaluation process in a distributed manner by the plurality of sequential mining servers 6A and 6B, it is possible to obtain a high evaluation result while preventing an excessive load on each server.

<Third Embodiment>
Next, a method for providing a plurality of SNSs based on the WEB site of the first embodiment or the second embodiment and allocating the revenue of the advertisement provided in the WEB site to each SNS is shown below.

  First, the plurality of application servers 2 shown in FIG. 1 provide web pages, exchange messages, provide an address book function, introduce a member (user) to other members, a bulletin board function shared among members, and the like. Execute and provide SNS throughout the WEB site.

  Here, a plurality of independent SNSs are provided to a WEB site composed of a plurality of application servers 2 and server computer groups. Within each SNS, parameters (evaluation items) such as member access frequency are totaled in real time by the mining agent 63 of the sequential mining server 6 and output as evaluation results. And below, let this evaluation result be the value of each SNS. Below, the example which evaluates the value of each SNS with the sequential mining server 6 of the said 1st Embodiment is shown.

Here, when a plurality of SNSs SNS-A to SNS-N exist on the WEB site, the value of each SNS is set to V (i) (where i = A to N). Then, the value V (i) is calculated by the following equation.
V (i) = (a × (number of members of SNS-i / total number of members of all SNSs) +
b × (number of active members of SNS-i / total number of active members of all SNS) +
c × (total number of accesses of SNS-i / total number of accesses of all SNSs) +
d × (Total stay time of SNS-i members / member stay time of all SNS)
/ (A + b + c + d) (1)
Here, a, b, c, and d are weighting counts set in advance based on the market situation. Moreover, an active member shows the member using SNS-i of the said WEB site at least once a week.

The value V (i) of the above equation (1) is a value between 0 and 1,
V (A) + V (B) + V (C) + V (D) + ... = 1
It becomes.

  As shown in the first embodiment, since the sequential mining server 6 obtains the evaluation result based on the log, no load is applied to the application server 2. For this reason, it is possible to realize data mining that does not stress the access of members of the WEB site.

Next, the advertisement revenue of the site provided by each SNS-i and the revenue R such as paid notice are assumed. The revenue R is distributed between the WEB site operator and the manager (community owner) of each SNS-i. The distribution ratio is, for example, 60%: 40%. The income R1 distributed to each SNS-i is a value obtained by multiplying the value V (i) obtained by the above equation (1) by a predetermined distribution ratio = 40%. That is,
R1 = V (i) × 0.4
It is.

  In the conventional SNS model, members were collected for free, and all advertisement / paid notice revenues were acquired by the service provider (WEB site operator). On the other hand, in the SNS of this embodiment, advertisements and paid notification revenues are distributed to all SNS-i community owners, thereby inducing efforts to increase the site population and access to each community owner. Is possible. In addition, the community owner of each SNS-i obtains the value V (i) from the mining server 6 sequentially using the WEB client 12, which leads to the access status and distribution of his / her SNS-i at a certain point in time. The value V (i) can be known in real time. Furthermore, the community owner of SNS-i can know the situation of other SNS-i by grasping the value V (i) of other SNS-i from the mining server 6 sequentially, and can grasp the competitive state. .

  As a result, activation of the WEB site can be expected, and further, the value to the advertiser is improved by this activation.

  Since the operation log of the user (member) is always secured in the log server 4, the number of accesses to a specific screen (screen on which an advertisement is displayed) and the staying time can be arbitrarily added up. Furthermore, the number of clicks on an advertisement link can be counted in real time in the evaluation command to the sequential mining server 6. For this reason, it becomes possible to change the item which evaluates value V (i) at any time.

  Note that the parameters for determining the value V (i) are not limited to the number of members and the number of accesses described above, and can be appropriately changed according to the SNS-i mode.

  In addition, the SNS-i provides a plurality of aggregates (such as SNS) for providing a service including a plurality of communities on a plurality of application servers 2 constituting a single platform. is there. The platform indicates a computer resource for providing a WEB site.

  In each of the above embodiments, an example in which the black board 62 is configured by a ring buffer has been described. However, the black board 62 may be provided with a storage area that holds a predetermined amount of the latest data, and is not limited to the ring buffer. Absent.

  In each of the above embodiments, the sequential mining server 6 is configured to receive logs from the user operation log server 4. However, the sequential mining server 6 only needs to be able to acquire the log of the application server 2, and thus the sequential mining server 6. May directly receive the log from the application server 2 or may sequentially provide the user operation log database 40 in the mining server 6.

  As described above, the present invention can be applied to a computer system that performs WEB site evaluation in real time.
