[Processing sequence]
FIG. 9 is a sequence diagram illustrating an operation in which the terminal 101 and the cloud service server A 131 execute a series of processes in the embodiment of the present invention.

  In F <b> 901, an electronic file upload instruction is issued by the user operating the Web browser of the terminal 101. In the electronic file upload instruction, the user designates an electronic file to be uploaded and inputs character string information of a message such as a message 711.

  In F902, based on the information input by the user in F901, the terminal 101 transmits the designated electronic file and the character string information of the input message to the cloud service server A131.

  In F903, the cloud service server A131 receives the electronic file and the message character string information transmitted from the terminal 101, and registers the message character string and the electronic file in the message DB 402. Further, the cloud service server A 131 analyzes the character string information of the message. If tag information is included, the tag information is extracted and registered in the tag DB 403. In the microblog function provided by the cloud service server A 131, when the user accesses, the message DB 402 and the tag DB 403 are referred to and a message or the like is displayed. As a result, when the registration in the message DB 402 and the tag DB 403 is completed in F903, the registered message or the like is displayed on the screen (FIG. 7) provided by the microblog function provided by the cloud service server A131. .

  In F904, similar to the electronic file upload instruction (F901), when the user operates the Web browser of the terminal 101 and inputs a comment for the message, the character string information input as the comment is transmitted to the cloud service server A131. To do.

  In F905, the cloud service server A131 receives the comment character string information transmitted from the terminal 101, and registers the comment character string information in the message DB 402. Further, the cloud service server A 131 analyzes the character string information of the comment. If tag information is included, the tag information is extracted and registered in the tag DB 403. F906 and F907 show how other users register comments as in F904 and F905.

  In F908, when the user B presses the acquisition button 713 for instructing to download the electronic file displayed on the Web browser of the terminal 101, a request for downloading the electronic file is sent to the cloud service server A131.

  In F909, the cloud service server A131 receives the request for downloading the electronic file from the terminal 101, and performs processing for analyzing the comment on the timeline. In the comment analysis process, the cloud service server A 131 first refers to the message DB 402 and extracts a message in which an electronic file is registered, an electronic file, and a comment related to the message. For example, the contents displayed in the message 711 and the comments 716 and 717 in FIG. 7 are extracted by this processing. Next, the cloud service server A 131 refers to the tag DB 403 and extracts tag information described in the extracted message or the like.

  Next, the cloud service server A 131 generates a URL character string indicating a Web page as a result of searching for a message or the like using the tag information as a keyword from the extracted tag information. Next, the cloud service server A 131 generates an electronic file in which the generated URL character string is embedded as a hyperlink in the header portion and footer portion of the electronic file acquired from the message DB 402.

  FIG. 8 shows an example in which an electronic file in which the generated URL character string is embedded as a hyperlink is displayed. Here, the URL character string to be generated is for displaying a Web page as a result of searching for a message or the like using the tag information as a keyword, but the information to be used as a keyword is not the tag information but the user name or the like. It doesn't matter. Also, what is embedded in the electronic file is not a character string such as a URL character string, but may be image data such as a QR code.

  In F910, the cloud service server A131 transmits an electronic file in which the URL character string is inserted to the terminal 101 of the user B as a response to the download request.

[Processing flow in cloud service server]
FIG. 10 is a flowchart for explaining the processing of the cloud service server A 131 to which the present invention can be applied. FIG. 10 illustrates a process in which the cloud service server A 131 registers character string information such as a message and an electronic file attached thereto in response to a request from the terminal 101 and downloads the electronic file in which the hyperlink is embedded to the terminal 101. . Each step shown in FIG. 10 is realized by the CPU 311 included in the cloud service server A 131 executing a control program.

  FIG. 10A shows the main flow of this processing. FIG. 10B shows the process of S1003 of FIG. 10A in more detail. FIG. 10C shows the process of S1005 of FIG. 10A in more detail.

  In S1001, the communication unit 411 in the Web application 401 of the cloud service server A 131 receives a request transmitted from the terminal 101 by a user operation. Then, the communication unit 411 passes the received request to the control unit 412.

  In step S1002, the control unit 412 analyzes the received request and determines whether or not this request is a comment registration request. If the request is a comment registration request (YES in S1002), the process proceeds to S1003. If the request is not a comment registration request (NO in S1002), the process proceeds to S1004.

  In step S <b> 1003, the control unit 412 passes the received comment registration request to the message management unit 413. The message management unit 413 that has received the comment registration request executes the comment registration process shown in FIG. Thereafter, the process proceeds to S1007.

  In step S1004, the control unit 412 analyzes the received request and determines whether the request is a file download request for downloading an electronic file. If the request is a file download request (YES in S1004), the process proceeds to S1005. If the request is not a file download request (NO in S1004), the process proceeds to S1006.

  In step S1005, the control unit 412 passes the received file download request to the message management unit 413. Receiving the file download request, the message management unit 413 executes the file download process shown in FIG. Thereafter, the process proceeds to S1007.

  In step S1006, the control unit 412 performs error processing on the assumption that an unexpected request has been received. The control unit 412 generates character string information of the error message, and embeds the generated character string information in the response data as an error. Next, the control unit 412 passes the generated response data to the communication unit 411. Then, the communication unit 411 transmits the response data to the terminal 101 as a response to the request received in S1001.

  In step S <b> 1007, the control unit 412 confirms the status of whether the cloud service being provided is stopped or terminated. If the cloud service has ended (YES in S1007), control unit 412 ends all processing. If the cloud service has not ended (S1007), the process proceeds to S1001 and waits until a request is received.

(Comment registration process)
The process of S1011 to S1014 shown in FIG. 10B is a flowchart for explaining the comment registration process of S1003.

  In step S1011, the message management unit 413 analyzes the received comment registration request, and extracts character string information such as a message and a registered user. When the message management unit 413 extracts a comment, the message management unit 413 extracts the message ID of the associated message. At this time, the comment is associated with one message. Next, the message management unit 413 analyzes the message and extracts tag information. Next, the message management unit 413 adds a new record to the message DB 402.

  In step S1012, the message management unit 413 determines whether an electronic file is attached to the received comment registration request.
