Description

  The present invention relates to a technique for providing another service on the Web that is linked to a service on the Web used by a user.

  In recent years, various services have been provided via the Web. Until now, information systems that were provided as packaged products have also been provided as services on the Web. An example of providing a service on the Web is a Web application (hereinafter referred to as a Web application), which receives a request from a client and returns the result to the client in HTML (HyperText Markup Language) format. It is possible to embed JavaScript, which is a script language, in this HTML, and to add functions that operate on the client side to the Web application.

  A proxy may be used to use this web application. The proxy here is a function that relays requests and responses between the client and the Web application. With this proxy, it is possible to filter the content provided by the Web application and obtain usage history. It is also possible to rewrite requests and responses that are information exchanged between the Web application and the client.

  Web services such as Web apps are provided by various organizations, organizations, and individuals. Clients can use public web services. However, the client does not use only a single service. The client may use the two services in cooperation, such as “use the output obtained as a result of using a certain service as the input of another service”. Hereafter, the former service is expressed as a cooperation source service, and the latter service is expressed as a cooperation destination service. However, the client must manually perform multiple tasks to link the services. Special techniques are required to save these efforts and make it easy to use services linked together.

  In order to link services, it is necessary to define in which link destination service the data output as a result of using the link source service is input. Therefore, there is a technique described in Patent Document 1 as a technique for inserting the output of a specific Web application into the input of a Web application to be used next.

  In the technique described in Patent Document 1, a Web application is a service, and the client defines the correspondence between the output of the cooperation source service and the input of the cooperation destination service as cooperation information between services. A client uses a certain service and another service in cooperation with each other by using such cooperation information between services.

  Embodiments according to the present invention will be described below with reference to the drawings.

"First embodiment"
Hereinafter, a first embodiment according to the present invention will be described with reference to FIGS.

  As illustrated in FIG. 1, the relay device 100 according to the present embodiment operates between a client terminal 200 and a service providing server 300. The service providing server 300 provides a client with a Web page expressed by a structured document such as HTML or XML as a service by executing the Web application 301.

  The relay device 100 transfers a request from the client terminal 200 to the server 300 and transfers a response from the server 300 to the client terminal 200. The relay device 100 is a computer, and communicates with the server 300 via a CPU 110 that executes various arithmetic processes, a storage device 120 such as a hard disk drive device, a memory 130 that serves as a work area of the CPU 110, and the network Na. A communication device 140a for communicating with the client terminal 200 via the network Nb. Although the communication devices 140a and 140b are provided on the server side and the client side here, it goes without saying that the communication with the server 300 and the client terminal 200 may be performed by one communication device.

  The CPU 110 functionally includes a request reception unit 111 that receives request information from the client terminal 200 via the communication device 140b, a request transfer unit 112 that transfers this request information to the server 300 via the communication device 140a, and a server Response receiving unit 113 that receives response information from 300 via communication device 140a, response transfer unit 114 that transfers this response information to client terminal 200 via communication device 140b, and request information received by request receiving unit 111 Are collected as input information, the input / output information collection unit 115 collects response information received by the response reception unit 113 as output information, and the server 300 based on the plurality of input / output information collected by the input / output information collection unit 115 Proposed A service linkage unit 116 that links the services to be linked, and a linked service information attachment unit 117 that attaches the service information linked by the service linkage unit 116 to the response information received by the response receiving unit 113. Have. Note that these functional units 111 to 117 all function when the CPU 110 executes the program 129 stored in the storage device 120.

  The storage device 120 stores the above-described program 129, the input / output information table 121 storing the input / output information collected by the input / output information collection unit 121, and the service linked by the service linkage unit 116. A service cooperation information table 122 that stores cooperation information between each other is provided.

  Next, a schematic operation of the relay device 100 described above will be described according to the sequence diagram shown in FIG.

  First, the client terminal 200 transmits request information to the server 300 that is a service provider (S1). The request receiving unit 111 of the relay device 100 receives the request information via the communication device 140b and transfers it to the input / output information collecting unit 115. The input / output information collection unit 115 uses the request information as input information, and stores a part of the input information in the input / output information table 121 (S2). The input information storage process (S2) will be described in detail later.

  The input / output information collection unit 115 transfers the request information, which is input information, to the request transfer unit 112 after storing the input information. The request transfer unit 112 transfers this request information to the server 300 via the communication device 140a (S3).

  Upon receiving this request information, the server 300 executes the Web application 301 corresponding to this request information, obtains a response to this request (S4), and transmits the response information to the relay device 100 (S5).

  The response reception unit 113 of the relay device 100 receives the response information from the server 300 via the communication device 140a and transfers it to the input / output information collection unit 115. The input / output information collection unit 115 uses the response information as output information, and stores a part of the output information in the input / output information table 121 in association with the information in the input information described above (S6). The output information storage process (S6) will be described in detail later.

  The service linkage unit 116 of the relay device 100 uses the plurality of input / output information stored so far in the input / output information table 121 to link services to create service linkage information. The service cooperation information table 122 is stored (S7). The service linkage processing (S7) here does not need to be synchronized with other processing. For example, even when the information relay between the client terminal 200 and the server 300 is frequent, only the input / output information is collected, and this service linkage processing (S6) is performed during the time when there is little relay. Good. The service linkage process (S7) will be described in detail later.

  Next, the cooperation service information attachment unit 117 searches the service cooperation information table 122 for service cooperation information associated with the response information from the response reception unit 113. And based on the service cooperation information acquired by the search, the cooperation service information linked to the response information is acquired, added to the response information, and passed to the response transfer unit 114 (S8). The cooperation service information attachment process (S8) will also be described in detail later.

  The response transfer unit 114 transmits the response information with the cooperation service information added to the client terminal 200 (S9). Thus, a series of processing ends.

  Next, detailed processing contents in the above-described input information storage processing (S2) and output information storage processing (S6) will be described.

  In the input information storage process (S2), the input / output information collection unit 115 extracts a referrer URL, a request destination URL, and request param information from request information that is input information to the server 300.

  Here, the referrer URL is the URL of the Web page that is the link source when a request is sent using a form or link. The request destination URL is a URL of a transmission destination when a request is transmitted using a form or a link. If the address is entered directly in the address bar of the Web browser, the entered address becomes the request destination URL. The above referrer URL and request destination URL information is extracted from the header of the request information transmission packet. The request param is data that can be said to be the main body of the request information, and is data that the client inputs to the client terminal 300, in other words, a parameter. This parameter is stored in the request information below the "?" Mark in the request destination URL when using the GET method. When POST method is used, it is stored in the part specified as the body in the request information. Further, the request param is expressed in the format of “request variable name = request value”. When there are a plurality of parameters, they are expressed by separating them with “&”.

  The input / output information collection unit 115 acquires the request acquisition time in addition to the above information. This request acquisition time is the time when the relay device 100 relays the request information from the client terminal 300.

  Then, the input / output information collection unit 115 sends the referrer URL, request destination URL, request acquisition time, and request param information extracted as described above, to the referrer URL area 121b in the input / output information table 121 shown in FIG. Stored in the destination URL area 121c, the request acquisition time area 121e, and the request param area 121g.

  In the output information storage process (S6), the input / output information collection unit 115 extracts the response URL, the response acquisition time, and the response body from the response information that is output information from the server 300.

  Here, the response URL is the URL of the Web page received after sending the request to the request destination URL. If there is no redirect processing that forwards the request, the request destination URL and the response URL match. The response body is data actually displayed by the client terminal 300 in the response information.

  The input / output information collection unit 115 acquires the response acquisition time in addition to the above information. This response acquisition time is the time when the relay device 100 relays the response information from the server 300.

  Then, the input / output information collection unit 115 stores the response URL, response acquisition time, and response body extracted as described above in the response URL area 121d, the response acquisition time area 121f, and the response body in the input / output information table 121 illustrated in FIG. Stored in the response body area 121h. At this time, the information extracted from the response information is stored in the same line as the line in which the information on the request information for the response information is stored in the input / output information table 121. That is, one row of the input / output information table 121 is filled by a series of processing from step 2 to step 6.

  Here, consider a scenario in which the user wants to search for a route to go to the exhibition hall X from Yokohama station, but does not know the nearest station of the exhibition hall X.

  In this case, as shown in FIG. 11, the client terminal 200 accesses the nearest station search service 10 and obtains nearest station search result information 15. Candidates for the nearest station for Exhibition Hall X include the main gate of International Exhibition Hall and Ariake. Then, the user who is the operator of the client terminal 200 determines that the main gate of the international exhibition hall is easy to use at the nearest station, accesses the route search service 20, enters Yokohama as the departure station, and enters the international station at the arrival station. Enter the main gate of the exhibition hall. Through the above operation, the user obtains route search result information 25 that is the original purpose.

  In the above scenario, the user requests the use of the nearest station search service 10 by typing “http://example.com/moyori” as a URL in the client terminal 200. The input / output information collection unit 115 of the relay device 100 acquires the referrer URL, request destination URL, request acquisition time, and request param information from the request information. Then, “1” is stored in the id area 121a of the input / output information table shown in FIG. 3, “unknown” is stored in the referrer URL area 121b of this line, and “http://example.com/” is stored in the request destination URL area 121c. “moyori”, “2008-07-07 10:00:00” is stored in the request acquisition time area 121e, and “none” is stored in the request param area 121g.

  In response to this request, the server 300 returns response information including the nearest station search reception information 11 shown in FIG. In FIG. 11, “Exhibition Hall X” is displayed on the display screen of the nearest station search reception information 11, but “Exhibition Hall X” is not displayed at this stage. The input / output information collection unit 115 of the relay device 100 acquires a response URL, a response acquisition time, and a response body from the response information. The id field 121a of the input / output information table 121 shown in FIG. 3 is a row “1”, the response URL area 121d is “http://example.com/moyori”, and the response acquisition time area 121f is “2008”. -07-07 10:00:10 ", the HTML document" <html> ... <form> ... </ html> "is stored in the response body area 121h.

  While viewing the nearest station search reception information 11 (FIG. 11), the user inputs “exhibition hall X” in the facility name / address input form in the information 11 and then clicks the submit button. The client terminal 300 transmits a request to the server 300 through the above processing. The input / output information collection unit 115 of the relay device 100 acquires the referrer URL, request destination URL, request acquisition time, and request param information from the request information. Then, “2” is stored in the id area 121a of the input / output information table shown in FIG. 3, “http://example.com/moyori” is stored in the referrer URL area 121b of this row, and “http://example.com/moyori” is stored in the request destination URL area 121c. “http://example.com/moyori/where”, “2008-07-07 10:00:45” is stored in the request acquisition time area 121e, and “where = exhibition hall X” is stored in the request param area 121g.

  In response to this request, the server 300 returns response information including the nearest station search result information 15 shown in FIG. The input / output information collection unit 115 of the relay device 100 acquires a response URL, a response acquisition time, and a response body from the response information. The id field 121a of the input / output information table 121 shown in FIG. 3 is a row “2”, the response URL field 121d contains “http://example.com/moyori/result”, and the response acquisition time field 121f “2008-07-07 10:01:00”, “<html> <body>... International Exhibition Hall Main Gate ... </ html>” which is an HTML document is stored in the response body area 121h.

  When the user obtains “international exhibition hall main gate” and “Ariake” as response parameters as candidates for the nearest station of “exhibition hall X” by the nearest station search service 20 (FIG. 11), , Search for the route from Yokohama to the nearest station. The response parameter is a portion indicating a response result to the request parameter in the response body, and is a portion excluding the template portion in the response body.

  Therefore, the user requests the use of the route search service 20 by typing “http://example.com/rosen” as a URL in the client terminal 200. The input / output information collection unit 115 of the relay device 100 acquires the referrer URL, request destination URL, request acquisition time, and request param information from the request information. Then, “3” is stored in the id area 121a of the input / output information table shown in FIG. 3, “Unknown” is stored in the referrer URL area 121b of this line, and “http://example.com/ is stored in the request destination URL area 121c. “rosen”, “2008-07-07 10:03:00” is stored in the request acquisition time area 121e, and “none” is stored in the request param area 121g.

  In response to this request, the server 300 returns response information including the route search acceptance information 21 shown in FIG. In FIG. 11, “Yokohama” and “Main Gate of International Exhibition Hall” are displayed on the display screen of the route search reception information 21, but these are not displayed at this stage. The input / output information collection unit 115 of the relay device 100 acquires a response URL, a response acquisition time, and a response body from the response information. The id field 121a of the input / output information table 121 shown in FIG. 3 is a line “3”, the response URL area 121d is “http://example.com/rosen”, and the response acquisition time area 121f is “2008”. -07-07 10:03:30 ", the HTML document" <html> ... <form> ... </ html> "is stored in the response body area 121h.

  While viewing the route search acceptance information 21 (FIG. 11), the user inputs “Yokohama” in the departure input form in this information 21 and “International Gate” on the arrival input form, and then submit button. Click. The client terminal 300 transmits a request to the server 300 through the above processing. The input / output information collection unit 115 of the relay device 100 acquires the referrer URL, request destination URL, request acquisition time, and request param information from the request information. Then, “4” is stored in the id area 121a of the input / output information table shown in FIG. 3, “http://example.com/rosen” is stored in the referrer URL area 121b of this row, and “4” is stored in the request destination URL area 121c. "http://example.com/rosen/kensaku", "2008-07-07 10:05:00" is stored in the request acquisition time area 121e, and "from = Yokohama & to = International Exhibition Hall Main Gate" is stored in the request param area 121g To do.

  In response to this request, the server 300 returns response information including the route search result information 25 shown in FIG. The input / output information collection unit 115 of the relay device 100 acquires a response URL, a response acquisition time, and a response body from the response information. Then, the id area 121a of the input / output information table 121 shown in FIG. 3 is a row of “4”, the response URL area 121d is “http://example.com/rosen/result”, and the response acquisition time area 121f is “2008-07-07 10:05:05”, the HTML document “<html> <body>... Shimbashi ... </ html>” is stored in the response body area 121h.

  As described above, when the user uses the two services of the nearest station search service 10 and the route search service 20, the input / output information table 121 shown in FIG. 3 is completed.

  Next, detailed processing contents in the above-described service linkage processing (S7) will be described with reference to the flowchart shown in FIG.

  When a new line is added to the input / output information table 121, the service linkage unit 116 acquires the input / output information of this line, and acquires the service specified by the input / output information of this line as the cooperation destination service information. (S701). For example, the input / output information of the line of id = 4 in the input / output information table 121 shown in FIG. 3 is acquired, and the service specified by this line is used as the cooperation destination service information. Then, the service cooperation unit 116 identifies candidates for cooperation source service information for the cooperation destination service information in the following processes of Steps 702 and 703.

  The service linkage unit 116 checks whether the referrer URL exists in the cooperation destination service information acquired in step 701 (S702). If the referrer URL does not exist, the service used before the cooperation destination service cannot be traced, so that the process is terminated because the service cannot be linked. If the referrer URL exists, the service used before the linked service can be traced, so the process continues. For example, since the referrer URL exists in the input / output information of the line of id = 4 in the input / output information table 121 shown in FIG. 3, the processing is continued.

  Next, the service linkage unit 116 checks whether there is output information (response information) of another service linked to the input information (request information) of the linkage destination service (S703).

  Here, the processing in step 703 will be described with reference to the flowchart shown in FIG.

  The service linkage unit 116 obtains from the input / output information table 121 the input / output information of other services acquired by the relay device 100 within the time ε and the response acquisition time is earlier than the request acquisition time of the cooperation destination service information. All are acquired (S731). This ε time means that it is sufficiently small, and is a parameter value given by the administrator of the relay device 100. If the value of ε is set to 1 hour, a service used by the user within the past 1 hour becomes a search target.

  Next, the service linkage unit 116 searches whether the request value of the request param of the link destination service information is included in the response body of the input / output information acquired in Step 731 (S732).

  At this time, using the characteristics of the structured document, information displayed on the Web page such as a character string enclosed in tags and a character string other than a comment is set as a search target. By doing so, it is possible to search only for information visible to the user. Searches also allow partial matches. If there is a matching response as a result, it is determined that there is output information linked to the cooperation destination service information (S733), and the process proceeds to step 704 in FIG. If there is no matching response, it is determined that there is no output information linked to the cooperation destination service information (S734), and the process is terminated.

  Here, there may be a plurality of matching parts in the same response body. In that case, priorities are assigned using the matching ratio of character strings and the characteristics of the structured document, and the character string with the highest priority is selected. As a specific prioritization method, for example, when the request value of the request parameter param of the link destination service information is “International Exhibition Hall Main Gate”, the “International Exhibition Hall” and “International Exhibition Hall” are included in the output information of other services. When there is a “main gate”, priority is given to the “international exhibition hall main gate” with many matching character strings. In addition, using the feature of the structured document, priority may be given to a character string that is displayed with emphasis or characters enlarged by tags. Furthermore, there may be a plurality of response bodies including a matching character string. In the case where there are a plurality of services, priority is given to those having a smaller difference between the request acquisition time of the cooperation destination service information and the response acquisition time of the service to be searched. For example, n services are selected as candidates for the linked service in order of service usage time. This n is a value set in advance by the provider of the service cooperation relay device 100. Further, it can also be used when calculating the cooperation strength of the service when performing the service linkage processing after Step 704.

  For example, in step 702, it is confirmed whether or not the referrer URL exists in the input / output information (cooperation destination service information) of the line of id = 4 acquired in step 701. In this case, the input / output information includes a referrer URL “http://example.com/rosen”. Then, the process proceeds to step 703, and in step 731 in FIG. 5, input / output information of other services having a response acquisition time before the request acquisition time “2008-07-07 10:05:00” of the cooperation destination service information. Are extracted from the input / output information table 121. In this case, input / output information of “id = 1”, “id = 2”, “id = 3” is extracted. Next, it is searched whether the request values “Yokohama” and “International Exhibition Hall Main Gate” of the request service param of the cooperation destination service are included in the response body of any of the input / output information extracted in Step 731 (S732). In this case, since the “International Exhibition Hall Main Gate” is included in the response body in the input / output information of “id = 2”, the service specified by the input / output information of “id = 2” is the link source service. It is judged that it is a candidate.

  When the identification of the cooperation source service candidate is completed (S703), the service linkage between the cooperation destination service information and the information of the cooperation source service candidate is performed in the processing of the following steps 704 to 710.

  First, the service association unit 116 extracts a referrer URL from the cooperation destination service information, and stores it in the cooperation destination service URL area 122b of the service cooperation information table 122 shown in FIG. 7 (S704). In this case, the referrer URL “http://example.com/rosen” of the cooperation destination service information (id = 4) is stored in the cooperation destination service URL area 122b.

  Next, the input / output information in which the referrer URL of the cooperation destination service information is the request destination URL is searched from the input / output information table 121, and from the response body, the request destination URL information of the target service, and the request variable name of the request param, The XPath at the position where the request param of the cooperation destination service information is input is extracted, and this XPath is stored in the cooperation destination service XPath area 122c of the service cooperation information table 122 shown in FIG. 7 (S705). In this case, find the input / output information of "id = 3" where the referrer URL "http://example.com/rosen" of the link destination service information (id = 4) is the request destination URL, and this input / output information XPath "/ html / body / div [in which the request variable name of" to = International Exhibition Hall Main Gate "included in the request param of the linked service information (id = 4) is defined at which position in the response body of 2] / form / input [@ name = 'to'] "is extracted. Then, this is stored in the cooperation destination service XPath area 122c of the service cooperation information table 122 shown in FIG. This is the input form in the route search reception information 21 included in the input / output information of “id = 3” for the cooperation destination service (id = 4) whose response body is the route search result 25 shown in FIG. This means that 22 positions are acquired.

Here, the request destination URL and the request variable of the request param are used because, for example, when the HTML form is used, the following information can be extracted as an XPath.
(1) From the request URL, you can see which form in the page is being used.
(2) From the request variable name of request param, you can see which name attribute in the form is used for the input tag.

  Next, the service cooperation unit 116 extracts the response URL “http://example.com/moyori/result” from the cooperation source service candidate information (id = 2) acquired in step 703, and this is shown in FIG. It is stored in the cooperation source output URL area 212d of the service cooperation information table 122 shown (S706). Furthermore, in the response body of the cooperation source service candidate, the position of the character string that matches the character string of the request service param of the cooperation destination service is extracted as XPath "/ html / body / div [3] / table / li [1]" This is stored in the cooperation source output XPath area 122e of the service cooperation information table 122 shown in FIG. 7 (S707). This is because, in the cooperation source service (id = 2) whose response body is the nearest station line search result 15 shown in FIG. 11, the character string “international” that matches the character string of the request param of the cooperation destination service (id = 4). This means that the position where the “exhibition hall front gate” is indicated, that is, the response parameter position 16 is acquired.

  Through the processing in steps 704 to 707, which service information result is used for the cooperation destination service information is associated. In other words, it becomes possible to know which service result is used as input of cooperation destination service information.

  Next, in the processing of the following steps 708 to 710, the service information input as a result of the input of the cooperation destination service information is associated.

  In step 708, the service linkage unit 116 checks whether the referrer URL exists in the linkage source service information acquired in step 703. If the referrer URL exists, it is determined that the cooperation source service information is obtained as a result of the input to the page indicated by the referrer URL, and the process proceeds to the next step 709. On the other hand, if the referrer URL does not exist, the process proceeds to step 711. In this case, since the referrer URL exists in the cooperation source service information (id = 2), the process proceeds to step 709.

  If the service linkage unit 116 determines in step 708 that the referrer URL exists in the link source service information, the service link unit 116 regards the referrer URL as an input page linked to the link destination service information, and this is the service link information shown in FIG. It is stored in the cooperation source input URL area 122f of the table 122 (S709). In this case, the referrer URL “http://example.com/moyori” of the cooperation source service information (id = 2) is stored in the cooperation source input URL area 122f of the service cooperation information table 122 shown in FIG.

  Next, the service association unit 116 searches the input / output information table for the latest input / output information in which the referrer URL of the cooperation source service information is stored as the request destination URL. In this case as well, priority is given to a service whose response acquisition time is close to the service request acquisition time. Then, the XPath of the position where the request is input is extracted from the response body of this input / output information, the request destination URL information of the linkage service, and the request param, and this is extracted from the linkage source input XPath area of the service linkage information table 122 shown in FIG. It stores in g (S710). In this case, the referrer URL “http://example.com/moyori” of the cooperation source service (id = 2) acquires the input / output information of “id = 1” that is the request destination URL. Then, from the response body of the input / output information of “id = 1”, the request variable name “where” of the request service param “where = exhibition hall X” of the cooperation source service (id = 2) is “id = 1”. Where the response body of the service is defined. Then, the XPath of the place where “exhibition hall x” is input can be acquired as “/ html / body / div [1] / form / input [@ name =’ where ’]”, for example. This XPath is stored in the cooperation source input XPath area 122g of the service cooperation information table 122 shown in FIG. This means that the position of the input form 12 in the nearest station search reception information 11 shown in FIG. 11 is acquired.

  Through the processing in steps 708 to 710 described above, it can be determined which service input is obtained as a result of the input of the cooperation destination service.

  Next, the service cooperation unit 116 obtains the cooperation strength between the cooperation destination service information and the cooperation source service information (S711). In order to obtain the cooperation strength, the time ε used in step 703 or the number n of candidates for the cooperation source service may be used. The service association unit 116 has the time ε and the number of candidates n. The values of these variables are set by the administrator of the relay device 100.

  When the time ε is used, for example, the cooperation strength S is obtained by the following equation.

S = (ε-difference between response acquisition time and request acquisition time) / ε
In this equation, the cooperation strength S increases as the service use time is closer.

  Further, when the number of candidates n is used, the cooperation strength S is obtained by the following equation by assigning the cooperation service detection ranks from 1 to n to the n candidates in the order of closest service use time.

  In this expression, the cooperation strength S increases as the order of detection as the cooperation source service becomes earlier.

S = (n + 1-linked service detection order) / n
By the way, after extracting the cooperation source service for a certain cooperation destination service, when extracting the cooperation source service for the same service as this cooperation destination service, the cooperation source service previously extracted by this cooperation source service May be the same.

  Therefore, the service cooperation attaching unit 116 removes the service cooperation information stored in one line of the service cooperation information table 122 and the cooperation strength in the above steps 702 to 711, and the same service cooperation information is stored in other lines. (S712). If there is the same service cooperation information, the cooperation strength in this service cooperation information is added to the cooperation strength of the target service cooperation information obtained in step 711, and this value is stored in the service cooperation information table 122. Stored in the cooperation strength area 122h of the target cooperation service row. If there is no same service cooperation information, the cooperation strength of the target service cooperation information obtained in step 711 is stored as it is in the service cooperation information table 122 in the cooperation strength area 122h of the target cooperation service row. To do. Thereby, the cooperation strength in the service cooperation information with high frequency used as service cooperation information increases.

  Next, the detailed processing contents in the above-described cooperation service information attachment processing (S8) will be described with reference to the flowchart shown in FIG.

When the cooperation service information attachment unit 117 receives the response information from the response reception unit 113 via the input / output information collection unit 115, all the response URLs included in the response information are included from the service cooperation information table 122. Service cooperation information is extracted (S801).
Next, the cooperation service information attachment unit 117 acquires one of the service cooperation information extracted in step 801 having the highest cooperation strength (S802), and executes the processes of steps 803 to 807 below. To do.

  The cooperation service information attachment unit 117 determines the following two conditions (a) and (b) for one piece of service cooperation information acquired previously (S803).

  (a) Does the response URL match the cooperation destination service URL in the service cooperation information?

  (b) Does the response URL match the cooperation source output URL in the service cooperation information?

  If it is determined in step 803 that both conditions (a) and (b) are No, the process proceeds to step 807 without performing any processing.

  If it is determined in step 803 that the condition of (a) is Yes and the condition of (b) is No, the response information is information of the cooperation destination service. Therefore, the cooperation service information attachment unit 117 adds this information to the response information. Information on the cooperation source service used before the cooperation destination service is attached (S804).

  Specifically, in step 804, the cooperation service information attachment unit 117 first acquires the cooperation source input URL from the service cooperation information acquired in step 802, and uses the service information defined by this URL as the cooperation source service information. Get as. Next, from the service linkage information acquired in step 802, the linkage destination service XPath and the linkage source input XPath are extracted, and the linkage destination service XPath and the linkage source input XPath are related. Then, the linkage source service information and the attribute information relating the linkage destination service XPath and the linkage source input XPath are attached to the response information.

  For example, as described above with reference to FIG. 11, consider a case where the user requests the use of the route search service 20 by typing “http://example.com/rosen” as a URL in the client terminal 200.

  At this time, the server 300 returns response information including the route search acceptance information 21 in response to this request. The response URL included in this response information is “http://example.com/rosen” as described above. Therefore, the cooperation service information attachment unit 117 acquires service cooperation information including this response URL from the service cooperation information table 122 (S801). In this case, in FIG. 6, the service cooperation information “id = 1” is acquired. Next, the cooperative service information attachment unit 117 determines the above-described conditions (a) and (b) (S803). In this case, since the response URL matches the cooperation destination service URL in the service cooperation information (id = 1) and does not match the cooperation source output URL, it is determined that this response information is information of the cooperation destination service, The process proceeds to step 804 in order to acquire information of the cooperation source service.

  In step 804, the cooperation service information attachment unit 117 acquires the cooperation source input URL “http://example.com/moyori” in the service cooperation information (id = 1), and is specified by this cooperation source input URL. Service information is acquired as linkage source service information. The cooperation source service information obtained based on this cooperation source input URL is information including the nearest station search reception information 11 shown in FIG. Therefore, when the cooperation source service information is attached to this response information and passed to the client terminal 200, the route search acceptance information 21 included in the response information from the server 300 is sent to the client terminal as shown in FIG. At the same time, javaScript is embedded so that the nearest station search reception information 11 is output. Further, in step 804, the linkage service information attachment unit 117 extracts the linkage destination service XPath and the linkage source input XPath from the service linkage information (id = 1), and relates the linkage destination service XPath and the linkage source input XPath. The attached attribute information is added to the above response information by JavaScript. Here, since the cooperation destination service XPath is the position of the input form 22 in the route search reception information 21, and the cooperation source input XPath is the position of the input form 12 in the nearest station search reception information 11, the client terminal 9, as shown in FIG. 9, the input form 22 in the route search reception information 21 and the input form 12 in the nearest station search reception information 11 are output so as to be related. Furthermore, with this attribute information of the association, the client terminal 200, for example, 1) when trying to input a character into the input form 22 in the route search reception information 21, the cursor is placed in the input form in the nearest station search reception information 11 2) This input form 12 lights up to prompt input here, and 3) Request parameters (exhibition hall X) are input to the input form 12 in the nearest station search reception information 11 Then, the response parameter (international exhibition hall main gate) obtained as a result is input to the input form 22 in the route search reception information 21 and the like.

  Returning to the description of the flowchart shown in FIG.

  If it is determined in step 803 that the condition (a) is No and the condition (b) is Yes, the response information is information of the cooperation source service, so the cooperation service information attachment unit 117 adds the response information to the response information. After attaching the information of the cooperation destination service used after this cooperation source service (S805), the process proceeds to step 807.

  Specifically, in this step 805, the cooperation service information attaching unit 117 first acquires the cooperation destination service URL from the service cooperation information acquired in step 802, and uses the service information specified by this URL as the cooperation destination service information. Get as. Next, the link source output XPath and the link destination service XPath are extracted from the service link information acquired in step 802, and the link source output XPath and the link destination service XPath are related. Then, the link destination service information and attribute information relating the link source output XPath and the link destination service XPath are attached to the response information.

  For example, as described above with reference to FIG. 11, the user inputs “http://example.com/moyori” as a URL to the client terminal 200 and executes a search using the nearest station search service 10. Think about the case.

  At this time, the server 300 returns response information including the nearest station search result information 15 in response to the search request. The response URL included in this response information is “http://example.com/moyori/result” as described above. Therefore, the cooperation service information attachment unit 117 acquires service cooperation information including this response URL from the service cooperation information table 122 (S801). Also in this case, the service cooperation information “id = 1” in FIG. 6 is acquired. Next, the cooperative service information attachment unit 117 determines the above-described conditions (a) and (b) (S803). In this case, since the response URL does not match the link destination service URL in the service link information (id = 1) but matches the link source output URL, it is determined that this response information is the link source service information. In order to acquire information on the cooperation destination service, the process proceeds to step 805.

  In this step 805, the cooperation service information attachment unit 117 acquires the cooperation destination service URL “http://example.com/rosen” in the service cooperation information (id = 1), and is specified by this cooperation destination service URL. Service information is acquired as linked service information. The cooperation destination service information obtained based on this cooperation destination service URL is information including the route search acceptance information 21 shown in FIG. Therefore, when the cooperation destination service information is attached to this response information and passed to the client terminal 200, the client terminal 200 searches for the nearest station included in the response information from the server 300 as shown in FIG. JavaScript is embedded so that route search acceptance information 21 is output together with the result information 15. Further, in step 805, the linkage service information attachment unit 117 extracts the linkage source output XPath and the linkage destination service XPath from the service linkage information (id = 1), and relates the linkage source output XPath and the linkage destination service XPath. The attached attribute information is added to the above response information by JavaScript. Here, the cooperation source output XPath is the position 16 where the character string “International Exhibition Hall Main Gate” in the nearest station search result information 15 is shown, and the cooperation destination service XPath is the input form of the route search reception information 21. 22, the client terminal 200 has a position (response parameter position) 16 where the character string “international exhibition hall main gate” in the nearest station search result information 15 is shown, as shown in FIG. 10. And the input form 22 in the nearest station search reception information 11 are output so as to relate to each other. Furthermore, the client terminal 200 arranges the cursor on the input form 22 in the nearest station search reception information 11 based on the attribute information of the association, or on the input form 22 at the position of the cooperation source output XPath. Processing such as arranging the character string “International Exhibition Hall Main Gate” shown is performed.

  9 and 10, there is one piece of cooperative service information 11 and 21 attached to the response information 21 and 15, respectively. However, a plurality of pieces of cooperative service information may be searched and attached. In such a case, the cooperative service information may be simply displayed side by side on the client terminal 200, or tabs 14 and 24 are provided for each cooperative service information, and the tabs 14 and 24 are clicked. Thus, the cooperative service information related to the tabs 14 and 24 may be displayed.

  Returning to the description of the flowchart shown in FIG.

  If it is determined in step 803 that both conditions (a) and (b) are Yes, the response information is information on the cooperation source service and information on the cooperation destination service. Attaches to the response information the information of the cooperation source service used before the response information as the cooperation destination service and the information of the cooperation destination service used after the response information as the cooperation source service. (S806), the process proceeds to step 807.

  Here, the method in which the cooperation service information attaching unit 117 attaches the information of the cooperation source service to the response information and the method of attaching the information of the cooperation destination service to the response information are the methods described in the above steps 804 and 805. And the same.

  In step 807, the cooperation service information attachment unit 117 determines whether the service cooperation information extracted in step 801 remains. If the service cooperation information remains, the process returns to step 802, and the cooperation service information attachment unit 117 acquires one of the largest cooperation strengths from the remaining service cooperation information, and has been described above. Steps 803 to 807 are executed.

  If the cooperation service information attachment unit 117 determines in step 807 that the service cooperation information extracted in step 801 does not remain, if the cooperation service information is attached to the response information in steps 804 to 806, Then, it is determined whether or not to further attach cooperative service information that cooperates with the cooperative service information (S808). This determination is made in advance by receiving an instruction from the client terminal 300 as to whether or not additional cooperative service information is to be attached to the cooperative service information, or the administrator of the relay device 100 adds additional cooperative service information to the cooperative service information. Whether or not to attach is set in advance, and is performed according to this instruction or setting.

  When the cooperation service information attachment unit 117 determines that further cooperation service information to be linked to the cooperation service information is attached, the cooperation service information attached to the response information is a new response in steps 804 to 806. After the information (S809), the process returns to step 801. In step 801, all service cooperation information including the response URL included in the new response information is extracted from the service cooperation information table 122, and the process proceeds to step 802 as described above. As described above, in steps 809 and 801, the search key (response URL) of the cooperation destination service information is changed, and the cooperation destination service information is searched again. At this time, in order to avoid an infinite loop of searching for cooperation destination service information, the response URL of the cooperation destination service information that has once become a search key is not used as a search key again. The provider of the relay device 100 sets the search key change count and change conditions. For example, if the search key change count is set to “0”, the linked service information is not searched for further linked service information. That is, the determination in step 808 is always No. On the other hand, if the change condition is, for example, “change the search key until there are no search key candidates”, the searched cooperative service is further used as the search key for the cooperative service information, and new cooperative service candidate information cannot be found. Search until.

  If the cooperation service information attachment unit 117 determines in step 808 that the cooperation service information to be cooperated with the cooperation service information is not further attached, only the response information or the cooperation service information is received in step 808. The attached response information is passed to the response transfer unit 114, and the cooperative service information attachment process (S8) is terminated.

  As described above, in the present embodiment, the relay device 100 defines cooperation information between services, and provides a service that cooperates with a service used by the user based on this definition. It is possible to eliminate the burden on the user when providing the service.

  Also, in this embodiment, if the response information is linked, both the linkage source service information and the linkage destination service information are attached, so that more linkage service information can be presented to the user. it can.

"Second embodiment"
Hereinafter, a second embodiment according to the present invention will be described with reference to FIGS.

  In this embodiment, when copy and paste is executed on the client terminal 200, a function for creating service cooperation information using this copy and paste information is added to the relay apparatus 100 of the first embodiment. is there.

  Therefore, the relay apparatus 100a of this embodiment has the same hardware configuration as that of the first embodiment, as shown in FIG.

  In addition to the functional configuration of the relay device 100 according to the first embodiment, the relay device 100a according to the present embodiment detects a copy event and a paste event in response information to be sent to the client terminal 200, and relays this to the relay device. An event detector attaching unit 118 for attaching an event detector as a program to be notified to 100a; and an event information receiving unit 119 for receiving event information from the client terminal 200. Similar to the other functional units, these functional units 118 and 119 also function when the CPU 110a executes the program 129a stored in the storage device 120a.

  In addition to the various tables 121 and 122 in the first embodiment, the storage device 120a of the present embodiment is provided with an event information table 123 in which event information received by the event information receiving unit 119 is stored.

  Since the relay device 100a of this embodiment also has the functional units of the relay device 100 of the first embodiment, FIG. 2, FIG. 4 and FIG. 5 are used similarly to the relay device 100 of the first embodiment. The same operation as described above is performed. Furthermore, when a copy and paste event occurs at the client terminal 200, the relay apparatus 100a of this embodiment additionally executes a service linkage process based on the copy and paste event.

  Hereinafter, the service linkage processing based on the copy and paste event in the present embodiment will be described with reference to the flowchart shown in FIG.

  The event information receiving unit 119 of the relay device 100a waits for reception of event information from the client terminal 200 (S751).

  The client terminal 200 includes an event detector that is a program received from the relay device 100a prior to transmission of event information to the relay device 100a. This event detector detects a copy event and a paste event, creates event information, and sends it to the relay device 100a. The event information includes information indicating whether the event is copy or paste, copy data or paste data, and data copy position XPath in the copy source service information or data paste position XPath in the paste destination service information. And the URL of the copy source service or the paste destination service.

  When receiving the event information, the event information receiving unit 119 determines whether the event information is copy event information or paste event information (S752). If the received event information is a copy event, the reception time of the copy event information is stored in the event information table 123 together with the copy event information (S753), and the process returns to step 751 to receive the paste event information. Wait for. If the received event information is paste event information, the paste event information is passed to the service linkage unit 116.

  When the service linkage unit 116 receives the paste event information from the event information reception unit 119, the service linkage unit 116 sets the same data as the paste data included in the paste event information as copy data at a predetermined time before receiving the paste event information. It is determined whether copy event information exists in the event information table 123 (S754). If the copy event information does not exist, the process returns to step 751, and if the copy event information exists, the process proceeds to step 755. For example, data copied from service information that does not pass through the relay apparatus 100a is not sent to the relay apparatus 100a, and therefore information on this data does not exist in the event information table 123. In this case, since the copy source service and the copy destination service cannot be linked, the process returns to step 751.

  If the copy event information corresponding to the received paste event information exists in the event information table 123, the service linkage unit 116 determines whether the input / output information corresponding to the copy event information exists in the input / output information table 121. It is determined whether or not (S755). Here, the URL of the copy source service included in the copy event information is the response URL, and the input / output information in which the copy data included in the copy event information exists in the response body is searched.

  If the input / output information corresponding to the copy event information is not in the input / output information table 121, the service cannot be linked, and the process returns to step 751. If the input / output information corresponding to the copy event information is in the input / output information table 121, the copy source service is set as the link source service, the paste destination service is set as the link destination service, and the following services in steps 756 to 762 are performed. Link up.

  First, the service linkage unit 116 extracts the URL of the paste destination service and the paste position XPath from the paste event information, and each of them extracts the link destination service URL area 122b of the service linkage information table 122 shown in FIG. Store in the cooperation destination service XPath area 122c (S756, 757).

  Subsequently, the URL of the copy source service and the copy position XPath are extracted from the copy event information, and these are respectively extracted from the link source output URL area 122d and the link source output XPath area 122e of the service link information table 122 shown in FIG. (S758, 759).

  Next, the service linkage unit 116 determines from the input / output information table 121 whether or not the referrer URL exists in the input / output information confirmed to exist in step 755, that is, in the link source service information corresponding to the copy event information. Is determined (S760). If the referrer URL does not exist in the collaboration source service information, the process proceeds to step 763. If the referrer URL exists in the collaboration source service information, the process proceeds to step 761.

  In step 761, the service linkage unit 116 searches the input / output information table for the latest input / output information in which the referrer URL of the link source service information is stored as the request destination URL, and the response body of the input / output information and the link service Is extracted from the request destination URL information and the like, and is stored in the cooperation source input XPath area g of the service cooperation information table 122 shown in FIG. 6 (S762). Note that the processing in step 762 is the same as the processing in step 710 described above with reference to FIG.

  This completes the association between services.

  Finally, the service linkage unit 116 obtains the link strength between the link destination service information and the link source service information, and stores this in the link strength area 122h of the service link information table 112 shown in FIG. 6 (S763). ), The service linkage process ends. In the calculation of the link strength here, for example, a formula for increasing or decreasing the strength according to the number of characters constituting the copy data or the tag information of HTML is prepared in advance, and this formula is used to calculate the link strength. In addition, in the service linkage processing based on the copy and paste event, a predetermined value may be used as the linkage strength.

  As described above, in the present embodiment, since the service cooperation information is created even at the time of the copy and paste event, more service cooperation information can be obtained, and as a result, a lot of cooperation service information is provided to the client terminal 300. can do.

"Third embodiment"
Hereinafter, a third embodiment according to the present invention will be described with reference to FIGS.

  The relay device of this embodiment is used on a SaaS platform. Here, SaaS is an abbreviation for Software as a Service, and distribution of services on the Web that allows only the functions required by the user among the software functions to be distributed and used via the Web. It is a form. The SaaS platform is a platform for operating software provided by a service provider in order to distribute services via the Web.

  As shown in FIG. 14, the relay device 100b of this embodiment is obtained by adding an input / output device 150 such as a keyboard and a display to the relay devices 100 and 100a of the first and second embodiments as a hardware configuration. is there.

  In addition, as a functional configuration of the relay device 100b of the present embodiment, in addition to the functional configuration of the relay device 100 of the first embodiment, each service linkage information in the service linkage information table 122 links information on a specific service. A specific service cooperation determination unit 161 that determines whether or not there is a need information provision unit 162 that causes the input / output device 150 to output service cooperation information that links specific service information in response to an instruction from the input / output device 150. Have. Similar to the other function units, these function units 161 and 162 also function by the CPU 110b executing the program 129b stored in the storage device 120b.

  In the storage device 120b of this embodiment, in addition to the various tables 121 and 122 in the first embodiment, a specific service information table 124 in which information on specific services is stored and a service in which information on specific services is linked. A cooperative use need information table 125 in which the cooperative information is stored is provided.

  In the specific service information table 125, a URL for receiving a specific service and a user ID when there is a user management function such as communication addresses and logins of all users who can use the specific service are mutually displayed. It is related and memorized. The data stored in the specific service information table 124 is periodically updated by the provider of the specific service via the input / output device 150 or the communication device 140a.

  In the service cooperation information table 122 of the present embodiment, each URL area 122b, 122d, 122f shown in FIG. 6 specifies a service specified by the stored URL in addition to the area where the URL is stored. A flag area indicating whether or not the service is provided is provided.

  Next, the operation of the specific service cooperation determination unit 161 will be described with reference to the flowchart shown in FIG.

  The specific service cooperation determination unit 161 waits until the search timing of the specific service is reached (S1501), and when the search timing is reached, extracts one service cooperation information from the service cooperation information table 122 (S1502).

  Next, the specific service cooperation determination unit 161 determines whether the service cooperation information extracted in step 1502 includes the URL of any specific service stored in the specific service information table 124 (S1503). .

  The specific service cooperation determination unit 161 ends the series of processes when the URL of the specific service is not included in the service cooperation information. If the URL of the specific service is included in the service cooperation information, a flag is set in the flag area regarding the URL in the line where the service cooperation information is stored in the service cooperation information table 122. Indicates that this URL is a URL of a specific service (S1504).

  Next, the specific service cooperation determination unit 161 stores the service cooperation information including the URL of the specific service in the cooperation use need information table 125, and ends the series of processes.

  Next, in accordance with the flowchart shown in FIG. 16, the linkage service information attachment processing in this embodiment will be described. In the figure, steps that perform the same processes as those shown in FIG. 8 are given the same step numbers, and detailed descriptions thereof are omitted.

If it is determined (S808), it is determined whether or not the previously attached cooperative service information is specific service information (S811). This determination is made by referring to the service cooperation information acquired in step 802 based on whether or not a flag indicating that the URL of the specific service is set for the URL of the cooperation service information.

  When the cooperative service information attachment unit 117 determines that the cooperative service information is not the specific service information, the process proceeds to step 810. When the cooperative service information attachment unit 117 determines that the cooperative service information is the specific service information, the process proceeds to step 812.

  In step 812, the linkage service information attachment unit 117 refers to the specific service information table 124 and determines whether or not the response information destination user can receive the specific service (S812). As described above, the specific service information table 125 includes a URL for receiving the specific service, and a user ID when there is a user management function such as communication addresses and logins of all users who can use the specific service. Are stored in association with each other, the link service information attachment unit 117 refers to the specific service information table 124 and sends the response information to the specific service information as the link service information. The above determination is made based on whether the communication address and the user ID are associated with each other.

  If the linked service information attachment unit 117 determines that the destination user of the response information can receive the specific service, the process proceeds to step 810. If the destination user of the response information determines that the specific service cannot be received, the process proceeds to step 813. .

  In step 813, the linkage service information attachment unit 117 attaches a recommendation such as “This service is charged. Please pay for the registration procedure.” To the linkage service information attached to the response information ( S813).

  Then, the cooperation service information attachment unit 117 passes the response information attached with the cooperation service information to the response transfer unit 114 (S810), and ends the attachment processing of the cooperation service information.

  In the present embodiment, even if the specific service cannot be used by the relay device 200b by performing the attachment process of the cooperation service as described above, the user can use the service if the cooperation service information is the specific service. The cooperation service information is output to the client terminal 200 along with the above-mentioned recommendation. Specifically, for example, as shown in FIG. 9, the nearest station search reception information (cooperation source service information) 11 for the route search reception information (response information) 21 is a specific service, and the user specifies this specification. When the service cannot be received, the client terminal 200 cooperates with the nearest station search acceptance information 11 together with the route search acceptance information (response information) 21 and the nearest station search acceptance information (cooperation source service information) 11. In addition, a recommendation such as “This service is charged. Please pay for the registration procedure” is displayed.

  Also, as shown in FIG. 10, the route search acceptance information (cooperation destination service information) 21 for the nearest station search result information (response information) 15 is a specific service, and the user cannot receive this specific service. In this case, the client terminal 200 is linked to the route search reception information 21 together with the nearest station search result information (response information) 15 and the route search reception information (cooperation destination service information) 21, and the above-mentioned recommendation. Is displayed.

  As described above, when the cooperation service information is a specific service, the recommendation is displayed together with the cooperation service information on the client terminal 200, so the user who is the user of the client terminal 200 is prompted to purchase the specific service. be able to. In addition, when a user who cannot use a specific service uses some data as input to the input form in the linked service information as the specific service, it is necessary to use the specific service, for example, the specific service. You will be asked to enter a valid password.

  In the present embodiment, the provider of the specific service accesses the needs information providing unit 162 via the input / output device 150 or the communication device 140a, so that the service cooperation information that links the information of the specific service is obtained. Can be acquired. For this reason, the service provider can know the service needs and the like from the usage status of the specific service, and can promote the development of a new service. Note that, here, only the service cooperation information that links the information of the specific service is acquired for the provider of the specific service, but the needs information providing unit 162 is based on the service cooperation information. , Response information, and specific service information linked to this response information, and in the same mode as the mode output to the user by the input / output device 160 or the like, that is, as shown in FIG. 9 and FIG. And specific service information linked to the response information may be output. Further, information indicating the user who received the recommendation together with the specific service information may also be output by the input / output device 160 or the like. This is because the cooperation service information attachment unit 117 determines that the destination user cannot receive the specific service in step 812 shown in FIG. This can be realized by linking and storing the service linkage information stored in the table 125.
