Description

  The present invention relates to a web page providing apparatus and a web page providing program suitable for use in a web server that provides a plurality of web pages.

  Web-based services for purpose-oriented tasks, such as searching for information that meets conditions, and procedures, are often composed of multiple pages. In general, the flow up to task achievement is designed by a flow designer and is not determined for each task, but is said to be based on the designer's experience. Currently, web systems can transition to various types of information by intra-page links, and the general method is to continue transitioning to the target information while following the links.

  Users are required to arrive at the target information as quickly as possible without rework, but in a web system where a large amount of information is stored in the screen, the content of the transition destination is determined only from the wording of the link. It is difficult to grasp, and when a plurality of options are prepared, an option that matches the purpose cannot be determined, and the process often proceeds with repeated rework. However, the more the transition progresses, the more difficult it is to determine where to go back. Eventually, the purpose may not be achieved due to repeated movements.

  To solve this situation, for websites that provide services across multiple pages, all pages are provided with two links: “to top of site” and “to previous page”. There are a lot of things. Furthermore, in order to make it easier for the user to grasp the transitions that have been traced so far, a method has been proposed in which a puncture list is displayed at the top and bottom of the screen.

  However, for beginners unfamiliar with the use of the web and users who access the site for the first time, it is possible to grasp the outline of the linked page only from the linked expression, and whether or not it is the page that is intended. It is difficult to judge.

  Generally, for beginners, it is said that it is easier to understand if the number of buttons (options) in one page is minimized. However, if the number of buttons in one page is suppressed, the number of pages (transitions) until the goal is achieved increases. As a result, when an erroneous selection is made, it is difficult to determine how far to return or where to return.

  Currently, there is no established method for taskflow design, and it is often based on the experience of the designer. However, in user interface design, the general view is that reversibility of the flow leads to improved usability. Yes, it is an implicit rule to provide the user with a return flow. In general, there are many configurations in which a normal flow up to the completion of a task has two links corresponding to returning to the top of the site and back to the previous page on all pages.

  “Previous one page” is often replaced with the browser's back button, but since beginners often do not know the functions of the browser, there is a case where a link “next one page” is provided. Many.

  However, these “Go to the top of the site” and “Previous page” links are effective for users who want to go back from the beginning and try again, or who noticed an error immediately after selection. For users who have noticed an error one step after achieving the goal, starting over from the beginning is a heavy burden, and for users who have noticed an error after going a few pages, going back one page, It does not correct the return.

  In addition, the punctures list that displays the transition history up to that point is a page where the experienced user who understands the overall structure of the site or the selection that was made on which page caused the error. It is effective for the user who can judge.

  However, for beginners, it is often difficult to know where the current page is due to the selection made. Many beginners often go back to the top of the site if they don't understand the cause of the current page. However, even if you return to the top of the site, it is difficult to find the wrongly selected page, and in many cases, the same wrong selection is repeated many times.

Until now, there have been several proposals for a method of presenting page transition history to the user in an easy-to-understand manner. Patent Document 1 proposes a method of dividing a screen into two and displaying a current page on one side and a page transition history of a user on the other side in a tree structure. Patent Document 2 proposes a method of displaying currently referred information and displaying information referred to in the past as a history in the order of reference on the same screen. Further, it is possible to select information to be browsed from the displayed history information, and further, layout information for determining the width and height when the history information is displayed on the screen is held.
JP 2004-362141 A JP-A-11-102314

  In Patent Literature 1, the screen is divided into two, and the current page is displayed on one side, and the page transition history of the user is displayed on the other side in a tree structure. This makes it possible for a user who has a clear location to return to clearly determine the return destination. Such a method is particularly effective for a site having a complicated hierarchical structure.

  However, in Patent Document 1, when a user who is not conscious of a place to return to or a case where trial and error is performed to correct an erroneous selection, the history shown in a tree shape is difficult for the user to understand. Expected effects are not much different from the current punks list.

  In Patent Document 2, information currently referred to is displayed and information referred to in the past is also displayed as a history in the order of reference on the same screen. The relative relationship of the traced information can be shown. In Patent Document 2, the relative relationship between the latest information and past captured information is always clearly displayed, so that the user who wants to return to past information can know the return location from the mutual positional relationship. It has the effect of being easily communicated.

  However, in Patent Document 2, when the user notices an erroneous selection, he / she reselects another link and repeats the determination as to whether the information is the target information. At this time, all trial and error histories in which erroneous selection has been repeated remain in the history display portion. For beginners unfamiliar with the operation, it is a problem that it is not possible to intuitively determine what selection process has been reached, and it is preferable to display the history or design the flow so that it can be determined how far to go back I think.

  As described above, the history shown in Patent Literature 1 and Patent Literature 2 can be displayed so as to serve as an index of a returning page. Such a history display is more effective than displaying only the page title as a punctuation list for users who can determine the return location when an error is noticed, and has the effect of helping to determine the return destination. it is conceivable that. However, for beginners, it is often impossible to determine on which page an error has been made, and the history display often causes confusion.

  In view of the above-described problems, the present invention provides a web page providing apparatus and a web page that enable even a beginner unfamiliar with a website to easily transition to a desired web page when browsing a plurality of web pages. The purpose is to provide the provided program.

  In order to solve the above problems, the present invention provides a task flow storage unit in which a task flow indicating the entire configuration of a site that provides a web page is stored as a tree structure, and a task flow of a tree structure of the task flow storage unit Based on the return destination list storage unit storing the return destination information of each web page and the request information sent from the user terminal, A user request analysis unit that determines whether the request is a “return” request or a “stop” request, and a task flow storage unit and a return destination list storage based on the request information determined by the user request analysis unit Transition destination page acquisition unit that acquires a web page transition destination candidate using the information of the part, and a transition destination page display information acquisition unit that acquires display information of the transition destination web page selected from the transition destination candidates And transition A web page providing apparatus characterized by preceding page display information acquisition unit is set to be from a transition execution unit for executing the transition to the web page of the transition destination acquired display information.

  According to the present invention, in the above described invention, the transition destination page acquisition unit selects the next web page as a transition destination candidate from the information in the task flow storage unit when the request information is “advance”. It is characterized by that.

  In the present invention described above, when the request information is “return”, the transition destination page acquisition unit represents the task flow of the web page in a tree structure from the information in the return destination list storage unit. If the web page corresponding to the root of the tree to which the selected page belongs and the tree to which the selected page belongs are nodes of another tree, The corresponding web page is selected as a transition destination candidate.

  In the present invention described above, the transition destination page acquisition unit selects the top web page of the site as a transition destination candidate when the request information is “interrupt”, or the site The feature is to stop providing web pages.

  The present invention provides a control computer of a web page providing apparatus, a step of saving a task flow indicating an entire configuration of a site that provides a web page as a tree structure in a task flow storage unit, and a tree structure of the task flow storage unit. Based on the task flow, the return information of each web page is stored in the return list storage unit, and the request information sent from the user terminal is analyzed. Determining whether the request is a “return” request or a “suspend” request, and information on the task flow storage unit and the return destination list storage unit is determined based on the determined request information. Using the step of acquiring the candidate destination of the transition destination of the web page, the display information of the transition destination web page selected from the transition destination candidates, and the display information is acquired. And a web page providing program for executing and performing transition to the transition destination web page.

  According to the present invention, based on the task flow storage unit in which the task flow indicating the configuration of each web page of the entire site that provides the web page is stored as a tree structure, and the task flow of the tree structure of the task flow storage unit Analyzing the return destination list storage unit storing the return destination information of each web page and the request information sent from the user terminal, whether the request information is a “forward” request or “return” Information on the task flow storage unit and return destination list storage unit based on the request information determined by the user request analysis unit and the user request analysis unit that determines whether the request is a request to “suspend” A transition destination page acquisition unit that acquires a transition destination candidate of a web page, a transition destination page display information acquisition unit that acquires display information of a transition destination web page selected from the transition destination candidates, and a transition First Di display information acquisition unit is set to be from a transition execution unit for executing the transition to the web page of the transition destination acquired display information. Thereby, even a beginner unfamiliar with the web can appropriately guide to a web page that the user wants to go to.

  According to the present invention, when the request information is “advance”, the transition destination page acquisition unit selects the next web page from the information in the task flow storage unit as a transition destination candidate. For this reason, even a novice user unfamiliar with the web can appropriately guide to the next page when the user wants to proceed to the next page.

  According to the present invention, when the request information is “return”, the transition destination page acquisition unit is selected when the task flow of the web page is represented by a tree structure from the information in the return destination list storage unit. If the web page that corresponds to the root of the tree to which the page belongs and the tree to which the selected page belongs are nodes of another tree, the web page that corresponds to the root of another tree that uses the tree of the selected page as a node Are selected as candidates for the transition destination. For this reason, even a novice user who is unfamiliar with the web can appropriately lead to a web page that the user wants to return to when the user wants to return.

  According to the present invention, when the request information is “interrupt”, the transition destination page acquisition unit selects the top web page of the site as a transition destination candidate or the web page of the site. I try to stop offering. For this reason, even a novice user who is unfamiliar with the web can appropriately guide whether to stop displaying the page, or to transition to the top page when the user wants to interrupt.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a system such as the Internet WWW (World Wide Web) to which the present invention can be applied.

  In FIG. 1, a user terminal 1 and a server 2 are connected via an Internet network 3. The user terminal 1 is installed with a browser 4 which is software used when a user browses a web page described in hypertext.

  The server 2 is a server that provides a site composed of a plurality of web pages. When the browser 4 is activated on the user terminal 1 and a URL (Uniform Resource Locator) indicating the location of the server 2 is input, the web page of the server 2 is displayed on the monitor 5 of the user terminal 1. On this web page, a multimedia screen composed of characters, images, sounds, etc. is displayed based on the description of the page language.

  In one embodiment of the present invention, as shown in FIG. 2, a “forward” button 11, a “return” button 12, and a “break” button 13 are displayed in the web page provided by the server 2. The

  The “forward” button 11 is a button for browsing the next web page. When the “forward” button 11 is clicked, the screen is guided to the screen of the next web page.

  The “return” button 12 is a button for returning to the previous web page. When the “return” button 12 is clicked, the server 2 sends a selection screen for returning to the web page that the user wants to return to. Specifically, the web page that the user wants to return is specifically the web page corresponding to the root of the tree to which the selected page belongs when the task flow of the web page of the server 2 is represented by a tree structure, and the currently selected page. If the tree to which the page belongs is a node of another tree, it is a web page corresponding to the root of another tree having the tree of the selected page as a node. This will be described later. The user can select a desired web page from the selection screen and return to a desired return destination web page.

  The “interrupt” button 13 is a button for ending browsing of the web page.

  FIG. 3 shows the server 2 for jumping to a desired web page so that it can be browsed by the “forward” button 11, the “return” button 12, and the “pause” button 13 as described above. The functional block diagram based on operation | movement is shown. In FIG. 3, it is assumed that a desired web page is stored in advance in the web page storage unit 61. The desired web page may be stored in an external server device so that it can be searched from the transition destination page display information acquisition unit 57 instead of the web page storage unit 61.

  In FIG. 3, the task flow storage unit 51 stores a task flow indicating the configuration of each web page of the entire site that provides the web page as a tree structure. For example, as shown in FIG. 4, a web page including pages P <b> 1 to P <b> 15 is shown in a tree structure, and task flow information of this tree structure is stored in the task flow storage unit 51.

  In the return destination list storage unit 52, a return destination list is created and stored with reference to the tree structure of the task flow storage unit 51. As shown in FIG. 5, the return destination list includes an item of the page name of the page and an item of information indicating whether the page corresponds to a root or a leaf in the tree (“0” for a root, leaf If the page corresponds to a leaf, the page name item corresponding to the root of the tree (Null if the page corresponds to the root), and the tree to which the page belongs are other trees. Information item (“0” for a section, “1” for a section) and whether the tree to which the page belongs is a section of another tree. The page name item of the page corresponding to the root of the tree with a node (Null if the tree to which the page belongs is not a node of another tree).

  For example, the return list of the page “P7” “remark selection” on the left side of the tree structure in FIG. 4 is as follows.

  The page name of this page P7 is P007. If it is html, “P007.htm” is described in the page name item. From FIG. 4, since page P7 is a leaf, “1” is described in the information item indicating whether the page corresponds to a root or a leaf in the tree. Since the page corresponding to the root of the tree to which the page P7 belongs is the page P4, the page name “P004.htm” of the page P4 is described in the page name item corresponding to the root of the tree. Since the tree to which the page P4 belongs is a tree node of the page P3, “0” is described in the information item indicating whether the tree to which the page belongs is a node of another tree. . “P003.htm” is described in the page name item of the page corresponding to the root of the tree having the page as a node.

  Similarly, the return destination list is generated for the other pages P1 to P15. The return destination list is stored in the return destination list storage unit 52.

  In FIG. 3, when any one of the “forward” button 11, the “return” button 12, and the “suspend” button 13 is selected on the user terminal 1, the request information is transmitted via the Internet network 3. The request information is received by the receiving unit 53 of the server 2 and sent to the user request analyzing unit 55.

  The user request analysis unit 55 determines from the request information received by the reception unit 53 whether one of the “forward” button 11, the “return” button 12, and the “pause” button 13 is selected. Then, depending on which button of the “forward” button 11, the “return” button 12, or the “interrupt” button 13 is selected, the transition destination page acquisition unit 56 selects a web page as a transition candidate destination. . At this time, the information in the task flow storage unit 51 and the information in the return destination list storage unit 52 are used to select a transition candidate destination web page.

  When the user request analysis unit 55 selects the “forward” button 11, the pop-up screen generation unit 61 creates a pop-up screen as to whether to select the target page. This pop-up screen is sent from the transmission unit 59 to the user terminal 1 via the Internet network 3. The user determines whether or not to select the target page, and operates the user terminal 1 according to the determination. Information about whether or not to select the target page is transmitted from the user terminal 1 to the server 2. Here, when information indicating that a target page is selected is returned from the user terminal 1, information that the transition destination page display information acquisition unit 57 selects a target page stored in the web page storage unit 61. Is read as transition destination page information, and the transition execution unit 58 executes transition to the transition destination web page. Information on the transition destination web page is transmitted from the transmission unit 59 to the user terminal 1 via the Internet 3, and the transition destination web page is displayed on the user terminal 1. At this time, the history information of the transition destination is stored in the transition history storage unit 60.

  When the “return” button 12 is selected by the user request analysis unit 55, the transition destination page acquisition unit 56 uses the information in the return destination list storage unit 52 to select a candidate web page as a transition candidate destination. Selected.

  For example, it is assumed that the “Return” button 12 is selected on the page P7 “select speech” on the left side of the tree structure in FIG. In this case, the return list of page P7 as shown in FIG. In the return destination list of page P7, the page name “P004.htm” of page P4 is described as the page corresponding to the root of the tree to which page P7 belongs. Therefore, the page P4 of “Method 1: Conference room selection” is selected as one of the return destinations of the page.

  Furthermore, the page name “P003.htm” of the page P3 is described as a page that is the root of another tree having the page P4 as a node from the return destination list of the page P4 shown in FIG. 6B. Accordingly, the page P3 of “method selection: (search from conference room, map)” is selected as the second return destination of the page.

  Further, from the return destination list of the page P3 shown in FIG. 6C, the page name “P002.htm” of the page P2 of “Purpose selection (viewing, posting)” is selected as a page that is the root of another tree having the page P3 as a node. Is described. Therefore, the page P2 for “purpose selection (viewing, posting)” is selected as the third return destination of the page.

  In this way, the return destination of the page “P7” of “speech selection” is page “P4” of “method 1: conference room selection”, page P3 of “method selection: (search from conference room, map)”, “ There are three pages P2 of “purpose selection (browsing, posting)”.

  In FIG. 3, the pop-up screen generation unit 61 creates a pop-up screen indicating the candidate destination page. This pop-up screen is sent from the transmission unit 59 to the user terminal 1 via the Internet network 3. From these candidate destination pages, the user operates the user terminal 1 to select a transition destination. The selected candidate destination page selection information is returned from the user terminal 1 to the server 2. Here, when selection information is returned from the user terminal 1, the transition destination page display information acquisition unit 57 displays the information of the web page corresponding to the selection information stored in the web page storage unit 61 as the transition destination page. The information is read as information, and the transition execution unit 58 executes transition to the transition destination page based on the selection information, and information on the transition destination web page is transmitted from the transmission unit 59 to the user terminal 1. On the user terminal 1, a transition destination web page is displayed. At this time, the history information of the transition destination is stored in the transition history storage unit 60.

  When the user request analysis unit 55 determines that the “interrupt” button 13 has been selected, the pop-up screen generation unit 61 creates a pop-up screen for selecting whether to end page browsing or start over from the beginning. . This pop-up screen is sent from the transmission unit 59 to the user terminal 1 via the Internet network 3. The user determines whether to end the page browsing or start over from the beginning, and selects whether to end the page browsing or start over from the beginning by operating the user terminal 1. The selection information for ending this page browsing or starting over from the beginning is returned from the user terminal 1 to the server 2. Here, when the information “end page browsing” is returned from the user terminal 1, the transmission of the page is ended. When the information of “redo” is returned from the user terminal 1, the screen transitions to the top web page of the site. Then, the transition destination page display information acquisition unit 57 reads the web page information corresponding to the selection information stored in the web page storage unit 61 as the transition destination page information, and the transition execution unit 58 returns to the top web page of the site. The information on the top web page of the site is transmitted from the transmission unit 59 to the user terminal 1.

  Next, the operation of the server 2 will be described with reference to FIGS.

  In FIG. 7, it is determined whether any one of the “forward” button 11, the “return” button 12, and the “suspend” button 12 is selected (step S1). When the forward button 11 is selected, the process for the forward button as shown in FIG. 8 is performed (step S2). When the return button 12 is selected, processing with the return button as shown in FIG. 9 is performed (step S3). When the button 13 to be interrupted is selected, processing with the button to interrupt is performed as shown in FIG. 10 (step S4).

  FIG. 8 shows processing when the forward button 11 is selected in step S2. When the forward button 11 is selected, the next page to be forwarded is selected with reference to the information in the task flow storage unit 51 in FIG. 8 (step S11). Then, a pop-up screen for making the user select whether to browse the target selection page is created, and this pop-up screen is transmitted to the user terminal 1 (step S12). After the pop-up screen is transmitted to the user terminal 1, it is determined whether or not information is returned from the user terminal 1 (step S13). When the information from the user terminal 1 is returned, it is determined whether or not to display the target page based on the information returned from the user terminal 1 (step S14). When browsing the target page, that is, when displaying, the transition to the next page is executed (step S15). If the target page is not browsed, the current page is maintained (step S16).

  FIG. 9 shows processing when the return button 12 is selected in step S3. When the return button 12 is selected, the return destination candidate destination page is determined with reference to the information in the return destination list storage unit 52 in FIG. 9 (step S21). Then, a pop-up screen for guiding to the return browse candidate page is created, and this pop-up screen is sent to the user terminal 1 (step S22). After the pop-up screen is transmitted to the user terminal 1, it is determined whether or not information from the user terminal 1 has been returned (step S23). When the information from the user terminal 1 is returned, it is determined which page is selected based on the information returned from the user terminal 1 (step S24). Then, based on the selected page, a transition to the page is executed (step S25).

  FIG. 10 shows processing when the button 13 to be interrupted is selected in step S3. When the “interrupt” button 13 is selected, a pop-up screen for selecting whether to end page browsing or start over from the beginning is created in FIG. 10, and this pop-up screen is sent to the user terminal 1 (step S31). . After the pop-up screen is transmitted to the user terminal 1, it is determined whether or not information from the user terminal 1 has been returned (step S32). When the information from the user terminal 1 is returned, it is determined whether to end the page browsing or start again from the beginning (step S33). When starting over from the beginning, a transition to the top page is executed (step S34). When the page browsing is ended, the transmission of the page is ended (step S35).

  11 to 17 show an example of a screen layout in an embodiment of the present invention. As shown in FIGS. 11 to 17, the screen layout is unified for each web page and is easy for the user to understand. Further, for example, in order to make the web page easy to understand, a method of clearly showing the page outline and the operation instruction to be performed at the top of each web page can be considered. At that time, if the page is a transition result from a certain page, it is easy to understand what is selected on the previous page and reached the current page at the top of the page overview.

  As shown in FIG. 11, a “forward” button 11, a “return” button 12, and a “suspend” button 13 are provided on the screen 70. As described above, when the “forward” button 11 is selected, the user is directed to the next screen. At that time, a pop-up screen is displayed so that the user can check the outline of the next screen.

  When the “forward” button 11 is selected on the screen shown in FIG. 11, as shown in FIG. 12, a pop-up screen 71 indicating whether or not it is possible to advance to the next page is displayed. This pop-up screen 71 includes a button 72 indicating that it is possible to proceed to the next page and a button 73 for rejecting advancement to the next page. When the button 72 is selected, transition to the next web page is made according to the tree-structured task flow stored in the task flow storage unit 51 as described above. When the button 73 is selected, it is refused to advance to the next page and the display of the current web page is continued.

  When the “return” button 12 is selected, referring to the information in the return destination list storage unit 52, as described above, if the selected page corresponds to a tree-structured section in the task flow, the selected item is being selected. The page that corresponds to the root of the tree to which the page belongs, and if the tree to which the selected page belongs is a node of another tree, the page that corresponds to the root of another tree with the tree to which the page belongs, etc. From the task flow, the corresponding root page is selected, and these page return destination candidates are selected. Then, as shown in FIG. 13, a pop-up screen 74 showing the return destination candidates is displayed. The pop-up screen 74 includes buttons 75a and 75b indicating return destination candidates. Here, when the buttons 75a and 75b indicating return destination candidates are selected by the user, the screen moves to the selected web page. A pop-up screen 74m displaying the candidates selected on the previous page is displayed at the top of the pop-up screen 74, and the pop-up screen 74m shows what is selected on the previous page and has reached the current page. Can be grasped.

  Further, when a transition corresponding to “return” is executed, if the transition after returning is the same as the previous transition, as shown in FIG. You may make it display the pop-up screen 76 which shows "it is good." This pop-up screen 76 includes a button 77 indicating that the same selection may be performed and a “reject similar selection” button 78.

  In addition, as shown in FIG. 15, a screen 79 that presents the user with a history indicating that this link has been selected in advance may be displayed in advance. The screen 79 includes a display 80 indicating that the previous selection has been made.

  When the “interrupt” button 13 is selected, as shown in FIG. 16, a pop-up screen 83 including two types of buttons 81 and 82 “end” and “restart from the beginning” is displayed.

  When the button 81 indicating "Finish" is selected, a screen 85 indicating a wording such as "Thank you for using" is displayed as shown in FIG. 17, and the display of the web page of the site is terminated. Is done. Further, a link button 84 such as “Close this screen” may be prepared for beginners.

  When the button 82 indicating “Redo” is selected in FIG. 16, the screen is shifted to the top screen of the site. Moreover, for beginners, at the time of transition, a display for confirming the outline of the next screen to the user may be performed.

  As described above, conventionally, the flow design of purpose-oriented tasks depends on the experience and know-how of designers, and there is no clear guideline. Because there are many services that provide two types of links “Previous Page” uniformly on all pages, it is very difficult for beginners and users who visit the site for the first time, and even if they feel that they want to return in the process of achieving their goals. , I do not know where to go, and often go back and forth. The present invention leads to the solution of such problems. In addition, this realizes a user interface that minimizes the number of tasks on one screen, and has the effect of suppressing the burden on the user even if the number of transitions is increased by suppressing the tasks on one screen. .

  The server 2 described above has a computer system inside. And the process which displays the web page mentioned above is memorize | stored in the computer-readable recording medium in the format of the program, The said process is performed when this computer reads and runs this program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
