Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an answer form processing system, an answer form processing method, a data processing system, a data processing method, and a program. 
       BACKGROUND ART 
       [0002]      FIG. 22  shows an example of a question form that is shown to a purchaser of an item on an e-commerce site. The question form is created on a computer in a text format by staff of a shop managing the e-commerce site. In the example of a question form shown in  FIG. 22 , a question sentence is placed at the head of lines in order to ask the purchaser if he/she has any request for a delivery date. The lines of options for delivery dates follow the question sentence. Text data of the question form is displayed on the purchaser&#39;s computer at the time of purchasing the item. The purchaser moves a cursor to any position on the question form with use of an input device, to thereby add or delete characters. 
         [0003]      FIG. 23  shows an example of an answer from the purchaser in reply to the question form, that is, an example of an answer form. As shown in  FIG. 23 , pursuant to the direction “please place a circle if you have a request for delivery date” in the question form, the purchaser adds a character in a parenthesis corresponding to one of the options included in the question form, thereby creating an answer form in text format for informing the shop staff of a wish to select the option. Such answer form is received and displayed on the computer of the shop, thereby enabling the shop staff to check the request for the delivery date etc. from the purchaser of the item. 
       SUMMARY OF INVENTION 
     Technical Problem 
       [0004]    However, among the options presented to the purchaser, what is important to the shop staff who has received the answer form is the portions to which the purchaser has added characters such as circles or crosses, that is, options actually selected by the purchaser. Displaying other options, to which such characters are not added, is unnecessary for the shop staff as well as consumes display space and distract the shop staff from smoothly confirming the answer form. 
         [0005]    For general text tools, programs called Winmerge, which highlights differences between old and new versions of the file, or FC and DIFF, which output and contrastively display differences between old and new versions of the file, are known. In these programs, however, in addition to the new version of the file, at least portions of the old version of the file corresponding to the changed portions of the new version are also displayed. As a result, display space is still consumed and the answer form is not smoothly examined. 
         [0006]    One or more embodiments of the present invention have been conceived in view of the above, and an object thereof is to provide an answer form processing system, an answer form processing method, a data processing system, a data processing method and a program capable of saving display space and outputting an answer form that is visibly easy to examine.

     DESCRIPTION OF EMBODIMENTS 
       [0042]    An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. 
         [0043]      FIG. 1  is a diagram illustrating the overall configuration of an e-commerce system according to an embodiment of the present invention. An e-commerce system  1  shown in  FIG. 1  includes an e-commerce server  4  mainly configured with a computer such as a server computer, a plurality of purchaser computers  6  each of which mainly configured with a computer such as a personal computer, a mobile phone, and a smartphone, and a plurality of shop computers  8  each of which mainly configured with a computer such as personal computer, a mobile phone, and a smartphone. Here, the e-commerce server  4  incorporates an answer form processing system, which is an embodiment of the present invention. All of the e-commerce server  4 , the purchaser computers  6 , and the shop computers  8  are connected to a communication network  10  capable of data communication such as the Internet, and are capable of mutually exchanging data. The purchaser computer  6  and the shop computer  8  are installed with web browsers, and access the e-commerce server  4 , thereby receiving data of a web page from the e-commerce server  4  and displaying the web page on a display. In the e-commerce system  1 , a virtual shopping mall is constructed on the e-commerce server  4 , and shop owners respectively having the shop computers  8  operate their virtual shops at the shopping mall. That is, each shop computer  8  records, at the e-commerce server  4 , information online of items, for example, price, details of items, and shipping date, with use of the web browser. Upon receiving a request from the purchaser computer  6 , the e-commerce server  4  provides information from the shops in web forms. The user of the purchaser computer  6  determines an item to purchase based on the provided information, and specifies the delivery address and payment option with use of the web browser. Processing of the delivery and payment is also performed by the e-commerce server  4 , and shops can check any time the result of the processing using a web browser of each shop computer  8 . 
         [0044]      FIG. 2  shows an example of an item screen provided by the e-commerce server  4  to the purchaser computer  6 . The screen is displayed on the web browser of the purchaser computer  6  based on the web page data sent from the e-commerce server  4 . For example, the item screen is displayed on the purchaser computer  6  by following a link on the top page of the e-commerce server  4  (not shown), or clicking a link button included in a search result list. The screen displays item information, such as an image, description, and price of the item. When purchasing an item, the purchaser inputs quantity into an input form  12  and clicks a button  14 , thereby storing an ID of the item displayed on the screen into a temporary storage area of the e-commerce server  4  in association with the purchaser computer  6  or the ID of the purchaser. In this way, conceptually, the item is put in a shopping cart. 
         [0045]    The screens provided to the purchaser computer  6  include buttons to access the shopping cart. By clicking the button, an order information input screen shown in  FIG. 3  is displayed on the purchaser computer  6 . This screen is displayed on the web browser of the purchaser computer  6  based on the web page data sent from the e-commerce server  4 , and provided for the purchaser to input information required for purchasing the item already in the shopping cart. That is, as shown in  FIG. 3 , the screen includes the name and price of the item that is specified by the ID stored, in the storage area of the e-commerce server  4  for the shopping cart, in association with the ID of the purchaser computer  6  or the purchaser. In addition, the screen includes input forms  16 ,  18 , and  20  for inputting the purchaser&#39;s name, address, and phone number. The purchaser inputs their name, address, and phone number into the input forms  16 ,  18 , and  20  respectively using an input device, such as a keyboard, of the purchaser computer  6 . The order information input screen further includes an input form  22 , in which a plurality of lines of text can be input, for inputting any other information. The input form  22  has default text of the question form that is sent from the shop computer  8  in advance. As such, the input form  22  is displayed in a state where the text of the question form is already input. The purchaser moves a cursor within the input form  22  using the input device of the purchaser computer  6 , such as a keyboard or a mouse, thereby adding or deleting any characters at the position of the cursor. In the example shown in  FIG. 3 , the number of lines of the text in the input form  22  is smaller than the number of lines of the text in the question form. As such, a scroll bar is displayed on the right side of the input form  22 . By operating the scroll bar, any portion of the text in the question form can be displayed in the input form  22 . 
         [0046]      FIG. 4  shows an example the text (text data) of the question form, which is sent from each shop computer  8  and recorded at the e-commerce server  4  in advance. The text is stored in the e-commerce server  4  in association with the shop computer  8  or the shop itself. When data of the web page of the order information input screen shown in  FIG. 3  is generated, the text of the question form, which is stored in advance in association with the shop that sells the item to be ordered or the shop computer  8 , is read out, and the text is set as the default value for the input form  22 . 
         [0047]    In the example shown in  FIG. 4 , the question form includes question sentences  30  described in two lines on the top, and question sentences  34  described in two lines on the middle. A group of options  32  described in a plurality of lines is arranged below the question sentences  30 , and a group of options  36  described in a plurality of lines is arranged below the question sentences  3 . Each line of the options  32  and  36  shows an option for the purchaser. 
         [0048]    Line 1 of the question sentences  30  describes “1: Gift Wrap”, and line 2 describes “please place a circle if you have a request for gift wrap.” Line 1 of the options  32  describes “ribbon ( )”, and line 2 describes “wrapping paper ( )”, and line 3 describes “message card ( 500  YEN) ( ).” In other words, the question sentences  30  ask if the purchaser has a request for gift wrap of the item, followed by three options: putting a ribbon on the box of the item, wrapping the box of the item with paper, and sending a message card with the item. When the purchaser wishes to put a ribbon on the box, the purchaser adds “o” in “ 0 ” described in line  1  of the options  32  to change “( )” to “(o).” When the purchaser wishes to wrap the box with paper, the purchaser adds “o” in “( )” described in line 2 of the options  32  to change “( )” to “(o).” When the purchaser wishes to add a paid message card to the box, the purchaser adds “o” in “( )” described in line 3 of the options  32  to change “( )” to “(o).” Here, not only one of the three options but multiple options may be selected at one time. However, depending on the questions and options, only one of the options should naturally be selected. 
         [0049]    Similarly, line 1 of the question sentences  34  describes “2: Delivery day”, and line 2 describes “please place a circle if you have a request for delivery day.” Lines 1-7 of the options  36  describe “Monday ( )”, “Tuesday ( )”, “Wednesday ( )”, “Thursday ( )”, “Friday ( )”, “Saturday ( )”, “Sunday ( )”, respectively. In other words, the question sentences  34  ask the purchaser which day of the week they wish to receive the item, followed by seven options from Monday to Sunday. The purchaser adds “o” in “( )” in the option of the desired day, thereby sending a request of the delivery day of the week to the shop. Here again, not only one of the seven options but multiple options may be selected at one time. 
         [0050]    The data of the question form shown in  FIG. 4  is set as the default value of the input form  22  on the order information input screen shown in  FIG. 3 , and the user can input characters in any portions as described above. The user inputs the character “o” according to the question sentences  30  and  34 , and as a result, the revised question form, that is, data of an answer form is generated.  FIG. 5  shows an example of data of an answer form. According to the data of the answer form shown in  FIG. 5 , the purchaser wishes to add wrapping paper and a paid message card as gift wrap, and selects Thursday and Saturday as a delivery day of the week. 
         [0051]    In the order information input screen shown in  FIG. 3 , the purchaser inputs their name, address, and phone number in the input forms  16 ,  18 , and  20  respectively, and inputs the character “o” in the parenthesis of the desired option in the input form  22  for the remarks. Subsequently, when the purchaser clicks the button  24 , data of each of input forms  16 ,  18 ,  20 , and  22  is sent to the e-commerce server  4  from the purchaser computer  6 . The received data of the input forms  16 ,  18 ,  20 , and  22  is temporary stored, and the e-commerce server  4  returns a review screen shown in  FIG. 6  to the purchaser computer  6 . The review screen is displayed on the web browser of the purchaser computer  6  based on the web page data sent from the e-commerce server  4 . The web page data is generated based on the content of input forms  16 ,  18 ,  20 , and  22  sent to the e-commerce server  4  from the purchaser computer  6 . The review screen shows the name, address, and phone number that the purchaser has respectively input in the input forms  16 ,  18 , and  20 , and only a portion of the input form  22 . Specifically, the review screen shows only lines to which the purchaser adds the character “o”. In this way, it is possible to save space for displaying the answer form on the review screen. In addition, only the lines to which the purchaser adds the character “o” are displayed, and thus the purchaser can immediately understand which options they have selected. By clicking the button  40 , it is possible to inform the e-commerce server  4  that the content of the review screen is correct. In this way, the temporarily stored name, address, phone number, and answer form are definitely stored in the e-commerce server  4  as order information. 
         [0052]    The order information stored as described above is also provided to the shop computer  8 . That is, when the shop staff accesses the e-commerce server  4  using the web browser of the shop computer  8 , the web page indicating the stored order information is sent to the shop computer  8 .  FIG. 7  shows an example of an order review screen displayed on the shop computer  8  based on the web page that is sent as described above. Similarly to the review screen shown in  FIG. 6 , the order review screen shows the name, address, and phone number that the purchaser has respectively input in the input forms  16 ,  18 , and  20 , and only a portion of the input form  22 . Specifically, the review screen shows only lines to which the purchaser adds the character “o”. In this way, it is possible to save space for displaying the answer form on the order review screen. In addition, only the lines to which the purchaser adds the character “o” are displayed, and thus the shop staff can immediately understand which options the purchaser has selected. By clicking the button  42  on the order review screen, for example, an order review screen regarding another order is displayed on the shop computer  8 . 
         [0053]    As described above, in order to display only the lines of the answer form to which the purchaser adds the character “o”, the e-commerce server  4  internally generates data of the revised answer form based on data of the question form and data of the answer form.  FIG. 8  shows data of the revised answer form that is generated for the review screen shown in  FIG. 6  and the order review screen shown in  FIG. 7 . The e-commerce server  4  compares content of the nth line of the answer form with content of the nth line (n is a number from  1  to the total number of lines in answer form) of the question form. If they are the same, the nth line of the answer form is not included in data of the revised answer form, and only if they are different, the nth line of the answer form is included in data of the revised answer form. As such, the data of the revised answer form is generated such that the lines of the options to which the character “o” is not added by the purchaser, who is an answerer, are omitted whereby the remaining lines are disposed adjacent in a line-by-line manner. In other word, the lines to which the answerer has added the character are coupled together according to the original order to generate data of the revised answer form. Subsequently, the data of the revised answer form is included in the review screen shown in  FIG. 6  or the order screen shown in  FIG. 7 , and displayed on the purchaser computer  6  or the shop computer  8 . 
         [0054]    In the above, each line of options has “( )”, however other types of parentheses, such as “[]” or “{}”, may be used. Alternatively, parentheses may not necessarily be described. In this case, the purchaser, who is the answerer, may be caused to add a character such as “o” after each option words. The character added to the line of the option may not be limited to “o”, but may be other characters such as “X” and “Y”. The character may, of course, include a plurality of letters, such as “YES”. The revised answer form as described above includes the line of the answer form to which the purchaser has added the character “o” as it is, however “(o) ” maybe deleted when the line is included in the revised answer form. 
         [0055]    In the following, specific processing for generating the review screen shown in  FIG. 6  and the order review screen shown in  FIG. 7  will be described.  FIG. 9  illustrates a functional block diagram of the e-commerce server  4 . As shown in  FIG. 9 , the e-commerce server  4  functionally includes a shop database  50 , an order database  52 , a shop recording unit  54 , an order information input unit  56 , an order information recording unit  58 , an order information review unit  60  and a communication unit  62 . The communication unit  62  sends and receives data with the purchaser computer  6  and the shop computer  8  through the communication network  10 . These elements are implemented by installing a program, which is an embodiment of the present invention, on the e-commerce server  4  and executing the program. The program may be downloaded from other computer through the communication network  10 , or installed from a computer readable storage medium such as a CD-ROM or a DVD-ROM. 
         [0056]    In addition to the elements shown in  FIG. 9 , the e-commerce server  4  includes other functional elements, such as item management or settlement for operating a virtual shopping mall. These functional elements can be of any constitution known in the art. As such, this embodiment mainly shows the review screen shown in  FIG. 6  and the portion relating to generating the order review screen shown in  FIG. 7 , which are the features of this embodiment, that is, the portion relating to the answer form processing system. 
         [0057]    In  FIG. 9 , upon receiving a request from a shop computer  8 , the shop recording unit  54  sends to the shop computer  8  the web page data of the information recording screen for recording the question form through the communication unit  62 . At the shop computer  8 , the data of the question form is input in the information recording screen. When the button on the screen is clicked, the data of the question form is returned to the shop recording unit  54 . The shop recording unit  54  converts the data of the question form received in this manner into a text file format shown in FIG. 
         [0058]      4 , and causes the shop database  50  to store the data for each shop. Upon receiving a request from a purchaser computer  6 , the order information input unit  56  sends to the purchaser computer  6  the web page data of the order information input screen shown in  FIG. 3  through the communication unit  62 . At this time, the order information input unit  56  reads out the data of the question form from the shop database  50 , and sets the data as a default value of the input form  22  of the order information input screen. 
         [0059]    When the button  24  on the order information input screen is clicked, content of the input forms  16 ,  18 ,  20 , and  22  is sent to the e-commerce server  4  from the purchaser computer  6 , and the communication unit  62  passes the information to the order information recording unit  58 . The order information recording unit  58  temporarily stores the received information, that is, the name, address, and phone number of the purchaser and the answer form. Based on the received information, the order information recording unit  58  generates the web page data of the review screen shown in  FIG. 6  and sends the generated data to the purchaser computer  6 . At this time, the review screen includes the data of the revised answer form. The data of the revised answer form is generated by the order information recording unit  58  such that the order information recording unit  58  obtains the data of the question form stored in the shop database  50  and the temporarily stored data of the answer form, and executes revised answer form generation processing ( FIG. 10 ) described below based on the obtained data. When the button  40  is clicked on the review screen, the order information recording unit  58  records the temporarily stored name, address, phone number and the answer form into the order database  52 . 
         [0060]    Upon receiving a request from a shop computer  8 , the order information review unit  60  sends web page data of the order review screen shown in  FIG. 7  through the communication unit  62 . At this time, the order review screen also includes the data of the revised answer form. The data of the revised answer form is generated by the order information review unit  60  such that the order information review unit  60  obtains the data of the question form stored in the shop database  50  and the data of the answer form stored in the order database  52 , and executes revised answer form generation processing ( FIG. 10 ) described below based on the obtained data. 
         [0061]    In the following, the revised answer form generation processing will be described.  FIG. 10  is a flow chart of the revised answer form generation processing executed by the order information recording unit  58  and the order information review unit  60 . As shown in  FIG. 10 , in the processing, 1 is substituted for a variable n, which indicates the number of lines (S 101 ). Subsequently, data of nth line is extracted from each of the question form data and the answer form data (S 102 ). At this time, if the data of nth line of the answer form is EOF (End Of File) , processing is ended (S 103 ). If not, the pieces of data extracted in S 102  are compared to determine whether or not the pieces of data match (S 104 ). If the pieces of data match, the variable n is incremented by 1 (S 106 ), and the processing returns to S 102 . If the pieces of data do not match, the data of the nth line of the answer form is added to the end of the data of the revised answer form (S 105 ). Subsequently, the variable n is incremented by 1 (S 106 ), and the processing returns to S 102 . With the above processing, the data of the revised answer form is generated such that the lines to which the character “o” is not added by the purchaser are omitted whereby the remaining lines are disposed adjacent in a line-by-line manner. 
         [0062]    The format of the revised answer form is not limited to the one shown in  FIG. 8 , but other variations may also be available. For example, as shown in  FIG. 11 , a blank line maybe inserted between pairs of the question sentence and the options. In this way, it is possible to easily recognize which answer belongs to which question. In the example of the question form shown in  FIG. 4 , blank lines are inserted between the first question sentences  30  and the group of options  32 , and between the second question sentences  34  and the group of options  36 . As such, in the flow chart of  FIG. 10 , even though the nth line of the question form matches the nth line of the answer form in S 104 , if these lines are blank (lines include only line feed codes), the blank lines maybe exceptionally added to the end of the data of the revised answer form. That is, the data of the revised answer form is generated such that the lines to which the answerer has added the character are coupled with the blank lines according to the original order. In this way, the revised answer form shown in  FIG. 11  is generated. 
         [0063]    Alternatively, in the revised answer form generation processing, lines suggesting question sentences in the answer form may be specified to be included in the revised answer form without restricting output of the specified lines of the question sentences in the answer form. In order to specify the lines of the question sentences, for example, lines in the answer form satisfying the predetermined condition may be specified as the lines suggesting the question sentences. Here, since the first line of each of the question sentences  30  and  34  starts with “&lt;”, a line satisfying the condition “including &lt; at the beginning of the line” may be specified as the line of the question sentences to be included in the revised answer form. In addition, a shop that creates a question form may be notified of a condition (e.g., including an asterisk at the beginning of the line) of a line of the question sentences to be included in the revised answer form. If the shop follows the condition to create the question form, the line satisfying the condition may be specified as the line of the question sentences to be included in the revised answer form. 
         [0064]      FIG. 12  is a flow chart indicating the revised answer form generation processing for generating a revised answer form that includes the lines of the question sentences to be specified. As shown in  FIG. 12 , in the processing,  1  is substituted for a variable n, which indicates the number of lines (S 101 ). Subsequently, data of nth line is extracted from each of the question form data and the answer form data (S 102 ). At this time, if the data of nth line of the answer form is EOF (End Of File), processing is ended (S 103 ). If not, the pieces of data extracted in S 102  are compared to determine whether or not the pieces of data match (S 104 ). If the pieces of data match, it is determined whether or not the nth line of the answer form satisfies the predetermined condition, for example, “including &lt;at the beginning of the line” (S 107 ). If the nth line does not satisfy the condition, the variable n is incremented by 1 (S 106 ), and the processing returns to  5102 . If the nth line satisfies the condition, the data of the nth line of the answer form is added to the end of the data of the revised answer form (S 105 ). Subsequently, the variable n is incremented by 1 (S 106 ), and the processing returns to S 102 . In S 104 , the nth lines of the question form data and the answer form data do not match, the data of the nth line of the answer form is also added to the end of the data of the revised answer form (S 105 ). Subsequently, the variable n is incremented by 1 (S 106 ), and the processing returns to S 102 . With the above processing, the data of the revised answer form is generated such that the lines are omitted except for the lines of the question sentences that satisfy the condition and the lines to which the character “o” is added by the purchaser. Here,  FIG. 13  shows an example of the revised answer form, which includes the first line of each of the question sentences  30  and  34 , generated by the processing shown in  FIG. 12 . In this revised answer form, the lines to which the answerer has added the character and the lines of the question sentences that satisfy the condition are coupled together according to the original order to generate data of the revised answer form. In this way, it is possible to understand a pair of a question and an answer in a direct way, and easily recognize content of the answer form. 
         [0065]    Instead of directly specifying the question sentences, lines of the options  32  and  36  of the question form may be specified first, and, based on the positions of the specified lines of the options  32  and  36 , the lines of the question sentences in the answer form maybe specified. In other words, the lines other than the specified lines of the options  32  and  36  may be specified as the lines of the question sentence. In order to specify the lines of the options  32  and  36 , for example, when a plurality of lines that satisfy the predetermined condition are consecutive, the consecutive lines may be specified as the lines of the options  32  and  36  of the question form. Here, each line included in the options  32  and  36  includes “( )”. As such, lines that satisfy the condition “including ( )in a line” may be specified as the lines of the options  32  and  36 . In addition, a shop that creates a question form may be notified of a condition of a line (e.g., including “.” at the beginning of the line, or including “[]”at the end of the line) of the question sentences to be included in the revised answer form. If the shop follows the condition to create the question form, a line satisfying the condition may be specified as the line of the options. 
         [0066]      FIG. 14  is a flowchart indicating another revised answer form generation processing for generating the revised answer form that includes the lines of the question sentences. As shown in  FIG. 14 , in the processing, a portion in which lines satisfying the predetermined condition are consecutive is specified (S 201 ). Here, line numbers in a portion in which a plurality of lines including “( )” at the end are consecutive are specified, but depending on a rule for creating the question form, line numbers in a portion in which a plurality of lines including “( )” at the beginning are consecutive maybe specified. The line numbers other than the line numbers specified in S 201  are then specified as the line numbers of the question sentence (S 202 ). 
         [0067]    Subsequently, 1 is substituted for a variable n, which indicates the number of lines (S 203 ). It is then determined whether or not n is included in the line numbers of the question sentences specified in S 202  (S 204 ). If not, the nth line of each of the question form data and the answer form data is extracted (S 205 ). At this time, if the data of nth line of the answer form is EOF (End Of File), processing is ended (S 206 ). If not, the pieces of data extracted in S 205  are compared to determine whether or not the pieces of data match (S 207 ). If the pieces of data match, the variable n is incremented by 1 (S 209 ), and the processing returns to S 204 . If the pieces of data do not match, the data of the nth line of the answer form is added to the end of the data of the revised answer form (S 208 ). Subsequently, the variable n is incremented by 1 (S 209 ), and the processing returns to S 204 . With the above processing, the data of the revised answer form is generated such that the lines are omitted except for the lines of the question sentences to which the character “o” is added by the purchaser. Here,  FIG. 15  shows an example of the revised answer form that includes the question sentences  30  and  34  and is generated by the processing shown in  FIG. 14 . In this revised answer form, the lines to which the answerer has added the character and the lines other than the lines of the options are coupled together according to the original order so as to generate data of the revised answer form. In this way, it is possible to include the question sentences  30  and  34  in the revised answer form, and, when checking the revised answer form, immediately understand which answer belongs to which question. 
         [0068]    Further, in the revised answer form generation processing, if the generated revised answer form is not added with a line, the revised answer form may include a message prepared in advance, such as “no entry.” As shown in  FIG. 16 , in a case where a portion of the question sentences is answered and the rest of the question sentences is not answered, it is preferable to record, in the revised answer form, whether the purchaser has answered or not for each question.  FIG. 17  shows an example of the revised answer form corresponding to the answer form shown in  FIG. 16 . In  FIG. 17 , the revised answer form displays, for each question, the answer from the purchaser if the purchaser has answered the question, and the message “no entry” is shown if the purchase has not answered the question. 
         [0069]      FIG. 18  is a flow chart showing the revised answer form generation processing for generating the revised answer form shown in  FIG. 17 . As shown in  FIG. 18 , in the processing,  1  is substituted for a variable n, which indicates the number of lines (S 301 ). Subsequently, data of nth line is extracted from each of the question form data and the answer form data (S 302 ). If the data of nth line of the answer form is not EOF (End Of File) (S 303 ), the pieces of data extracted in S 302  are compared to determine whether or not the pieces of data match (S 304 ). If the pieces of data do not match, the data of the nth line of the answer form is added to the end of the data of the revised answer form (S 310 ). Subsequently, the variable n is incremented by 1 (S 311 ), and the processing returns to S 302 . If the pieces of data match, it is determined whether or not the nth line of the answer form satisfies the predetermined condition, for example, “including &lt; at the beginning of the line”(S 307 ). If the nth line does not satisfy the condition, the variable n is incremented by 1 (S 311 ), and the processing returns to S 302 . If the nth line satisfies the condition, it is determined whether or not one or more lines have been added to the revised answer form from the last time the line satisfying the condition was found to this time (S 308 ). If not, a line of the message “no entry” is added to the end of the revised answer form (S 309 ), and then the data of the nth line of the answer form is added to the end of the revised answer form (S 310 ). Subsequently, the variable n is incremented by 1 (S 311 ), and the processing returns to S 302 . If it is determined one or more lines have been added to the revised answer form in S 308 , the processing skips S 309 . 
         [0070]    In S 303 , if it is determined that the nth line of the answer form data is EOF, it is determined whether or not one or more lines have been added to the revised answer form from the last time the line satisfying the condition was found to this time (S 305 ). If not, a line of the message “no entry” is added to the end of the revised answer form (S 306 ), and the processing is ended. If one or more lines have been added, the processing skips S 306 . With the above processing, the data of the revised answer form is generated such that the lines are omitted except for the lines of the question sentences that satisfy the condition and the lines to which the character “o” is added by the purchaser, and the message “no entry” is added to the question sentences to which the purchaser has not answered. With this revised answer form data, it is possible to surely recognize which question is not answered. 
         [0071]    In a case where an amount of text of the answer form and the question form is small, there is little need to omit the same lines in the answer form and the question form to dispose the remaining lines adjacent in a line-by-line manner. As such, if the amount of text of the answer form and the question form is less than the predetermined amount, the revised answer form may not be generated and the answer form may be displayed without being changed on the review screen in  FIG. 6  or the order review screen in  FIG. 7 . Here, the amount of text may be the total number of lines in the answer form or the question form, or the number of characters. Alternatively, the amount of text may be an amount of data. As shown in  FIG. 19 , the order information recording unit  58  and the order information review unit  60  determine whether or not an amount of text of the answer form is predetermined amount or more (S 401 ). If the amount of text of the answer form is equal to or more than the predetermined amount, any of the revised answer form generation processing described above is executed (S 402 ). If the amount of text of the answer form is less than the predetermined amount, the answer form is output without being changed. Subsequently, the order information recording unit  58  and the order information review unit  60  include the data output in S 402  or S 403  in web data of the review screen shown in  FIG. 6  or the order review screen shown in  FIG. 7 . In S 401 , the amount of text of the answer form is checked, but an amount of text of the question form may, of course, be checked too. In this way, in a case where an amount of text is small (e.g., the number of lines is less than  10 ) as the question form shown in  FIG. 20 , the answer form shown in  FIG. 21  is to be included in web data of the review screen shown in  FIG. 6  or the order review screen shown in  FIG. 7  without being changed. 
         [0072]    According to the e-commerce system  1  as described above, only the necessary portions of the answer form generated by the purchaser are displayed on the review screen shown in  FIG. 6  or the order review screen shown in  FIG. 7 , and thus the display space can be effectively used. In addition, the purchaser and the shop staff can immediately understand content of the answer. In the above, the example in which the present invention is applied to the question to the purchaser at the time of order of an item is described. However, the present invention may similarly be applied to other question forms, such as a question form for asking for a review after the purchaser uses the e-commerce system  1 . Further, the answer form processing according to the embodiment of the present invention may be executed by a server computer such as the e-commerce server  4 , or by a client computer such as the purchaser computer  6  or the shop computer  8 . Alternatively, a portion of the answer processing according to the embodiment of the present invention may be executed by the server computer, and the rest of the processing may be executed by the client computer. The server computer may consist of a plurality of computers.
