[0017] Hereinafter, a list providing device 10 according to an embodiment of the present invention will be described with reference to the drawings, in which the same or corresponding parts are given the same reference numerals.

[0018] 1 is a functional block diagram showing a functional configuration of a list providing device 10 according to the present embodiment. The list providing device 10 is composed of an acquisition unit 101, a list display unit 102, a detailed information display unit 103, and a change unit 104. The list providing device 10 is connected to a server 20 via a communication network such as the Internet.

[0019] The acquiring unit 101 acquires list data from the server 20. The list data is data for displaying a list on the list providing device 10. The list data is transmitted from the server 20 to the list providing device 10 in response to a list data acquisition request from the list providing device 10, for example. Note that the list data may be automatically transmitted from the server 20.

[0020] The list data is, for example, data showing a list in which summary information of a plurality of items is arranged. In this embodiment, a search request is transmitted from the list providing device 10 to the server 20 in response to a user operation or the like, and list data corresponding to the search result is transmitted from the server 20 in response to the search request. The server 20 is, for example, a web server that stores items (contents) to be searched, and transmits to the list providing device 10, in response to a request from the list providing device 10, web page data for searching for items and web page data for displaying a list in which summary information of items in the search results is arranged.

[0021] The list display unit 102 displays a list corresponding to the list data acquired by the acquisition unit 101 on the display of the list providing device 10. The list display unit 102 displays a scrollable list in which summary information of a plurality of items corresponding to the list data is arranged.

[0022] In response to the selection of a link to detailed information of an item included in the list displayed by the list display unit 102, the detailed information display unit 103 displays detailed information of the selected item on the display (screen) of the list providing device 10. When displaying the detailed information, the detailed information display unit 103 shifts the focus target from the list to the detailed information.

[0023] The items displayed as a list may be any information displayed as a list. For example, the items may be information about products, services, delivery services, digital content such as books, comics, music, videos, accommodations, transportation, travel tours, restaurants, recipes, real estate, beauty facilities such as beauty salons and esthetic salons, leisure facilities such as golf courses, campsites and fishing boats, sporting events, etc. The list may allow detailed information about the items to be viewed via the list, and the items may be purchased or reserved.

[0024] The list providing device 10 displays the list and detailed information on, for example, a web browser displayed on a display. In this embodiment, it is assumed that the list and detailed information are displayed on a tab browser capable of displaying multiple web pages in one window. The list display unit 102 displays a list corresponding to the list data in one tab. When a link to detailed information of an item is selected in the list, the detailed information display unit 103 adds a new tab and displays detailed information of the selected item in the new tab, and also shifts the focus to the detailed information by displaying the new tab in the foreground (activating it).

[0025] When the focus target is moved to the list after the detailed information is displayed, the change unit 104 changes the order or format of the summary information arranged in the list that is not yet displayed on the screen according to the similarity with the displayed detailed information and the viewing status of the displayed detailed information. For example, in the case of adopting a tab browser, when the tab of the list returns to the active state after the tab of the detailed information becomes active, the change unit 104 changes the display order or format (display mode) of the summary information included in the part of the list before scrolling according to the similarity with the displayed detailed information and the viewing status of the displayed detailed information. Specifically, when the degree of viewing of the displayed detailed information is low, the change unit 104 determines that the user has little interest in the item corresponding to the detailed information, and changes the order or format of the summary information in the list so that the summary information of the item that is highly similar to the item becomes less noticeable. For example, the change unit 104 reduces the display size of the summary information in the list or postpones the display order of the summary information in the list, thereby lowering the display priority of the summary information. In addition, the change unit 104 may exclude the summary information in the list from the display target as the above-mentioned format processing.

[0026] In this way, items that are expected to be useful to the user can be made prominent in the list while items that are of little interest to the user are made less prominent.

[0027] The list providing device 10 is, for example, a communication-enabled information processing terminal such as a personal computer (PC), a smartphone, a tablet, etc. Note that the list providing device 10 may be a dedicated device.

[0028] 2 is a diagram showing an example of a hardware configuration of the list providing device 10. The list providing device 10 has a processor 11 such as a CPU (Central Processing Unit) or a GPU (Graphical processing unit), a storage device 12 such as a memory, an HDD and / or an SSD, a communication interface 13 for performing wired or wireless communication, an input device 14 for accepting input operations, and an output device 15 for outputting information. The input device 14 is, for example, a keyboard, a touch panel, a mouse and / or a microphone, etc. The output device 15 is, for example, a display and / or a speaker, etc.

[0029] The processor 11 reads a program stored in the storage device 12, and thereby operates as various functional units shown in FIG.

[0030] Next, the operation of the list providing device 10 will be described. Fig. 3 is a flowchart showing an example of the list providing process executed by the list providing device 10. The processor 11 of the list providing device 10 executes the list providing process at a predetermined timing (for example, the timing when a predetermined operation of the user is accepted). In the list providing process, first, the processor 11 (acquisition unit 101) of the list providing device 10 determines whether or not list data has been received from the server 20 (step S11). If list data has not been received (step S11; No), the list providing process is terminated.

[0031] As a preliminary step before receiving list data, the list providing device 10 transmits a list acquisition request to the server 20 when it accepts an operation to acquire list data by the user. In this embodiment, when the processor 11 of the list providing device 10 accepts a search operation for an item (product, facility, etc.) as an operation to acquire list data by the user, the processor 11 of the list providing device 10 transmits a search request indicating the search contents to the server 20 as an example of a list acquisition request. In response to this search request, the list data is transmitted from the server 20 to the list providing device 10 as a search result. Note that the operation to acquire list data may be other operations such as an operation of an acquisition button, and the list acquisition request may be transmitted from the list providing device 10 to the server 20 in response to the acquisition operation. In addition, the list data may be actively transmitted from the server 20.

[0032] When list data is received (step S11; Yes), the processor 11 (list display unit 102) displays a list of multiple items corresponding to the list data on the display of the list providing device 10 (step S12). Specifically, the list display unit 102 displays a list of summary information of multiple items in a scrollable manner on the active tab of the tab browser (for example, the tab that displayed the item search screen). While the tab displaying the list (list tab) is active, that is, while the list is the focus object on the screen, if the processor 11 detects a scroll operation by the user, it scrolls the list up and down in response to the operation. Note that there may be cases where the list is displayed in a manner that makes it impossible to scroll, such as when the number of items included in the list is small.

[0033] After displaying the list, the processor 11 monitors the amount of scrolling to monitor the viewing status of the summary information in the list (step S13). Specifically, the processor 11 obtains the screen size and amount of scrolling of the list tab to monitor whether each piece of summary information has been displayed in the list tab (viewed by the user) or not, and records the result. This makes it possible to determine which summary information has been displayed and which summary information has not been displayed in the list tab in the process described later.

[0034] Next, processor 11 determines whether summary information is selected from the displayed list (step S14). Specifically, processor 11 determines whether a selection operation of a link to detailed information included in the summary information in the list is detected.

[0035] When summary information is selected in the list (step S14; Yes), the processor 11 (detailed information display unit 103) opens a new child tab associated with the list tab, activates the child tab, and displays detailed information corresponding to the selected summary information in the child tab (step S15). This moves the focus from the list tab to the child tab displaying the detailed information. Such a child tab is generated, for example, by a script program on the list tab side. A child tab displaying detailed information is also called a detail tab. Note that detailed information corresponding to summary information may be obtained from the server 20.

[0036] Then, processor 11 monitors the viewing status of the opened detail tab (step S16). Specifically, processor 11 monitors the time during which the detail tab was the focus target, the scroll amount of the detail tab, whether the detail tab was closed, etc. In this way, the degree of viewing of detailed information such as the viewing time of the user's viewed tab and the viewed part is monitored.

[0037] After that, processor 11 determines whether the focus has moved to the list tab (step S17). In step S17, processor 11 determines whether the list tab has been selected or whether the details tab has been closed and the list tab has become active. If the focus has not moved to the list tab (step S17; No), the process returns to step S16.

[0038] If the focus has moved to the list tab (step S17; Yes), it is determined whether or not the degree of browsing of the detailed information is less than a predetermined value based on the browsing status of the detailed information monitored in step S16 (step S18). In step S18, for example, processor 11 quantifies the degree of browsing of the detailed information based on the time during which the detailed tab was the focus target and the scroll amount of the detailed information tab, and determines whether or not the quantification is less than a predetermined value at which the degree of browsing can be determined to be low.

[0039] Also, in step S18, for example, processor 11 may determine whether the time during which the details tab was the focus target is less than a predetermined time, whether the scroll amount of the details tab is less than a predetermined amount, whether specific information has not been viewed based on the scroll amount, etc. Then, if at least any of the conditions is satisfied, it may be determined that the degree of viewing of the information is less than a predetermined value. For example, if the item is a facility, the specific information may be information that can be determined to indicate high interest in the item, such as reservation information for the facility.

[0040] If the degree of viewing of the detailed information is less than a predetermined value (step S18; Yes), that is, if the detailed information is not viewed much and the details tab is closed, or the focus returns to the list tab and the detailed information is not viewed much, items similar to the item in the opened detailed information are extracted from the items included in the list (step S19). In step S19, processor 11 may, for example, determine that an item having attribute information in common with the opened detailed information is similar and extract it. The attribute information is information that can determine the similarity of the items, and may be, for example, information that can classify the items. Specifically, if the item is a product, it may be a product category or price range, etc., and if the item is a facility, it may be a region, price range, equipment, etc.

[0041] Also, in step S19, processor 11 may extract an item whose first view is similar to the opened detailed information. The first view is the first screen when the detailed information tab is opened, and is a portion of the detailed information that can be viewed without scrolling the detailed information tab. The first view being similar may be an appearance similar or may include similar information.

[0042] When similar items are extracted, processor 11 changes the appearance of summary information of the extracted items whose summary information is not displayed in the list tab (step S20). Specifically, processor 11 changes the appearance so that summary information of an item similar to an item corresponding to detailed information whose degree of browsing is less than a predetermined value is not noticeable. Any method for changing the appearance of the summary information may be used, for example, changing to a simplified display that is simpler than normal summary information. The simplified display may be, for example, a display that is smaller than normal or that contains less information. At this time, a message indicating that the display is simplified may also be displayed. Whether or not the summary information is not displayed in the list tab is determined based on the browsing status of the summary information started in step S13.

[0043] In this embodiment, if the degree of browsing of the detailed information is less than a predetermined value, the user determines that the item is not useful, and among the summary information of items similar to the item, those that are not displayed before scrolling are changed to a simplified display to make them less noticeable. This makes it possible to relatively highlight the summary information of other items, and to provide the user with a list of items that are expected to be useful according to the user's browsing status of the detailed information.

[0044] In step S20, instead of or in addition to changing the appearance of the summary information of the extracted items, the display order of the summary information of the extracted items may be changed. That is, the display order of the summary information of the extracted items may be changed to be after other summary information. In this way, changing the display order of the summary information in the list according to the browsing status of the detailed information may be limited to cases where the display order of the list is not specified by the user, for example, where the list is displayed in "recommended order". In this way, it is possible to prevent the list from being displayed in an order unintended by the user.

[0045] To change the format or display order of the summary display, the DOM (Document Object Model) of the corresponding summary information in the list data can be rewritten. In this way, when the list tab is scrolled and the summary information is displayed, it is displayed in the changed format or display order.

[0046] If no similar items are extracted in step S19, the process in step S20 may be omitted.

[0047] If summary information is not selected in the list (step S14; No), if the degree of browsing of detailed information is equal to or greater than a predetermined value (step S18; No), or after the process of step S20 is executed, it is determined whether the list tab has been closed (step S21). If the list tab has been closed (step S21; Yes), the list providing process is terminated, and if the list tab has not been closed (step S21; No), the process returns to step S13 and continues.

[0048] Next, examples of display of the list providing device 10 according to the present embodiment will be described with reference to Fig. 4 to Fig. 8. Here, the description will be given on the assumption that the item is golf course information (golf course reservation information) and the server 20 is a web server of a golf course reservation site.

[0049] 4 to 8, an example will be described in which the appearance of summary information in the list is changed according to the similarity of the detailed information at first sight. Specifically, the similarity is determined according to whether or not emergency notice information is included in the detailed information at first sight.

[0050] Note that, here, an example is described in which the appearance of summary information in the list is changed depending on the similarity of the first view of detailed information. However, in addition to or instead of changing the appearance of summary information in the list, the display order of summary information in the list may also be changed.

[0051] In this embodiment, when the item is reservation information for a facility, the detailed information can include emergency notice information indicating suspension or restriction of use of the facility. Specifically, the emergency notice information can be displayed at the first view of the details tab. In this way, a user who has viewed the detailed information can be notified of suspension or restriction of use before the reservation is restricted on the system, and it is possible to prevent the user from making a reservation without knowing that the facility is suspended or restricted. The emergency notice information is, for example, a notice that the facility is closed due to bad weather, a disaster, maintenance, or the like, or a notice that there is a restriction on use. In addition, in FIG. 4 to FIG. 8, the similarity is determined depending on whether the first view of the detailed information includes emergency notice information.

[0052] Fig. 4 shows an example of a list displayed in the web browser 100 on the screen of the list providing device 10. Here, it is assumed that a search has been made for golf courses in the Kanto-Koshinetsu region that can be booked on July 12th. Fig. 4 shows that 602 golf courses have been found as the search results, and a list 110 of the search results is displayed in order of recommendation in the web browser 100. The web browser 100 is a tab browser, and the list 110 of the search results is displayed in tab 1 (list tab).

[0053] List 110 includes a plurality of pieces of summary information o1 to o3. The plurality of pieces of summary information o1 to o3 include the prefecture in which the golf course is located, the name of the golf course, an overview (icon, text, etc. showing the course overview), fee information for reservation plans, etc. The golf course names of each piece of summary information o1 to o3 are links l1 to l3, and when the golf course name (link l1 to l3) is selected, detailed information about each golf course is displayed.

[0054] Furthermore, in the state shown in FIG. 4, when the list tab is scrolled by scrolling the scroll bar 120 or by a mouse, the list 110 is scrolled, and the summary information above and below the list 110 can be viewed.

[0055] When the link l1 (golf course name in the summary information) of "aa golf club" is selected in the state where the list 110 is displayed as in Fig. 4, for example, a new tab 2 (details tab) is generated and the focus is shifted to the details tab, and detailed information 130 of "aa golf club" is displayed in the details tab as shown in Fig. 5. The detailed information 130 includes the prefecture where the golf course is located, the name of the golf course, an image of the golf course, a course introduction (text showing course details, etc.), access information, course information (number of holes, total distance, elevation difference, etc.), facilities and services, reservation information 140, etc. When the details tab is scrolled by using the scroll bar 120 or a mouse scroll operation in the state shown in Fig. 5, further information such as weather forecast and word-of-mouth information can be viewed.

[0056] As described above, the detailed information 130 can include emergency notification information indicating the suspension or restriction of use of the facility, and in Fig. 5, emergency notification information 150 regarding the operation of the golf course is displayed at the top of the first view of the detailed information 130. For example, the emergency notification information 150 can notify the user that a part or all of the golf course is unavailable or closed due to bad weather, disaster, maintenance, etc.

[0057] When a golf course is closed, it is possible to prevent reservation information 140 from being displayed in the detailed information, or to prevent the golf course from being included in search results, but there is a possibility that users may access the detailed information between the time the course is closed and the time reservations are restricted on the system. In this case, by quickly posting emergency notice information 150 in detailed information 130, users who have viewed detailed information 130 can be notified of the suspension or restriction of use before the system restricts reservations, and it is possible to prevent users from making reservations without knowing that the course is closed or restricted.

[0058] After the detailed information 130 is displayed on the screen, the degree of interest of the user in the detailed information 130 can be understood to some extent by the viewing status such as the viewing time and the scroll amount. Therefore, in this embodiment, when the detailed tab is opened, the viewing status of the detailed tab (viewing time, scroll amount, etc.) is monitored while the detailed tab is the focus target. Then, depending on whether the viewing degree is less than a predetermined value, the degree of interest of the user in the detailed information 130 displayed in the detailed tab is judged. For example, if the detailed tab is closed within a predetermined time (e.g., 5 seconds) after the detailed tab is opened, if the focus target returns to the list tab within a predetermined time, or if a scroll operation for viewing the reservation information 140 that is cut off in FIG. 5 is not detected, it can be judged that the user has little interest in the item corresponding to the detailed tab (here, the golf course information of "aa golf club" and its reservation information). Also, if the detailed tab is the focus target for a predetermined time or more after the detailed tab is opened, or if a scroll operation for viewing the reservation information 140 is detected, it can be judged that the user has a high interest in the item corresponding to the detailed tab.

[0059] 5, when detailed information 130 including emergency notice information 150 is opened at first view and it is determined that the degree of browsing of detailed information 130 is less than a predetermined value, it can be determined that the user has little interest in the golf course including emergency notice information 150. In other words, it is expected that the user will not make a reservation at a golf course where emergency notice information 150 is included in detailed information 130 and use is suspended or restricted. If the detailed information is subsequently opened from the list and emergency notice information is included again, the user may feel annoyed.

[0060] Therefore, when it is determined that the degree of browsing of the detailed information 130 is less than a predetermined value, an item in which the emergency notice information 150 is included in the first view of the detailed information is extracted as an item similar to the detailed information 130 shown in Fig. 5. Then, among the summary information corresponding to the extracted items, the appearance of the summary information not displayed in the list tab is changed so as to be less noticeable.

[0061] When the details tab is displayed as in Fig. 5, if the details tab is closed, the focus returns to the list tab, and the state returns to that shown in Fig. 4. Here, if the list tab is scrolled by a scroll operation, the list 110 scrolls, and the summary information below the list 110 is displayed.

[0062] When it is determined that the degree of browsing of the detailed information 130 shown in Fig. 5 is less than a predetermined value, summary information o4 of an item that has not been displayed in the list tab and that includes emergency notice information 150 in the first view of the detailed information is displayed in a simplified manner as shown in Fig. 6. The simplified summary information o4 is displayed in a collapsed manner and includes the prefecture in which the golf course is located, the name of the golf course, and a notice that emergency notice information is available. Additionally, summary information o5 and o6 of items that do not include emergency notice information 150 in the first view of the detailed information are displayed in a normal manner.

[0063] Note that items corresponding to summary information that was not displayed on the screen in Fig. 4 and was scrolled and first displayed on the screen in Fig. 6 include "a2 golf club," "dd country club," and "bbb golf club," and Fig. 6 shows an example in which only the detailed information of "a2 golf club" contains emergency notice information 150. Even when the list 110 is scrolled further down to display summary information further down, summary information whose detailed information includes emergency notice information 150 will be displayed in a simplified display.

[0064] In Fig. 4, when the link l1 of "aa golf club" is selected and the details tab shown in Fig. 5 is displayed, if the details tab is immediately closed, the display returns to that shown in Fig. 4. If the list tab is then scrolled, the display becomes as shown in Fig. 6. In this case, the screen transition is as follows: Fig. 4 → Fig. 5 → Fig. 4 → Fig. 6.

[0065] In this way, according to the list providing device 10 of this embodiment, by making the summary information o4 of the item with emergency notice information, which is expected to have little interest to the user, less noticeable, it is possible to prevent the user from viewing the detailed information of the item with emergency notice information again. Also, since the summary information of other items can be made to stand out relatively, it is possible to provide the user with a useful list.

[0066] Furthermore, in the list providing device 10 of this embodiment, since the order or format of only the summary information not yet displayed on the screen is changed, the order or format of the list can be changed without the user noticing.

[0067] In addition, in the simplified display as shown in Fig. 6, the fact that there is emergency notification information is displayed, so the user can understand the reason for the simplified display. This makes it possible to display information that is expected to cause the user to skip without viewing the detailed information. This also makes it possible to prevent the user from becoming suspicious, and to provide the user with a list that is suitable for them.

[0068] In addition, if "aa golf club" does not include emergency notice information, when the link l1 of "aa golf club" is selected, detailed information 131 that does not include emergency notice information at first view is displayed in the details tab as shown in FIG. 7. In such a case, it is not necessary to execute a process for changing the format and order of summary information according to the viewing status of detailed information 131. Also, in such a case, the format and order of summary information that has not yet been displayed on the screen may be changed based on the similarity of the detailed information other than the first view. For example, the format and order of summary information that has not yet been displayed on the screen may be changed based on the viewing status of detailed information 131 and the similarity of other attribute information (region, price range, golf information characteristics, etc.).

[0069] In addition, if no processing has been performed to change the format or order of the summary information, such as when detailed information including emergency notification information has not been opened or when the degree of viewing of detailed information including emergency notification information is equal to or greater than a predetermined value, when scrolling from the screen shown in Figure 4, a list 110 including summary information o4' in the normal display format as shown in Figure 8 will be displayed.

[0070] (Modification) The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. For example, some of the above-described embodiment may be omitted or replaced, or any configuration may be added.

[0071] In addition to or instead of changing the display mode of the summary information arranged in the list, an example of changing the display order of the summary information arranged in the list will be described. For example, as shown in FIG. 9, assume that the original list includes summary information 1 to summary information 7, and summary information 1 and summary information 4 include emergency notice information. Of these, only summary information 1 and summary information 2 are already displayed on the screen. In this case, when detailed information of summary information 1 is opened and the browsing degree of the detailed information of summary information 1 is less than a predetermined value, the display order of summary information 4 including emergency notice information is similarly moved to the end. In this way, summary information 4 including emergency notice information can be made less noticeable, making it easier for the user to browse other items and to focus on other items.

[0072] 4 to 8, an example has been described in which the change unit 104 of the list providing device 10 determines the similarity between items depending on whether or not emergency notice information is included in the first view of the detailed information, but the method of determining the similarity of the first view is not limited to this. For example, the similarity of the first view may be determined depending on the similarity of character information or images included in the first view of the detailed information. That is, the similarity of the first view may be determined by any method.

[0073] Furthermore, the change unit 104 of the list providing device 10 is not limited to changing the order or format of the summary information according to the similarity of the detailed information at first view, but may change the order or format of the summary information in the list according to the similarity with the information (text information, image, etc.) displayed in the detailed information immediately before the detailed information was closed or the focus was returned from the detailed information to the list. In other words, the similarity between the detailed information displayed on the screen and the items in the list may be determined by any method.

[0074] The change unit 104 of the list providing device 10 may change the format or order of summary information in the list that has not yet been displayed on the screen, based on the similarity between the list and multiple detailed information displayed on the screen after the list is displayed on the screen and the viewing status of multiple detailed information displayed on the screen. For example, attribute information that is common or frequently appears in detailed information that has been displayed on the screen but has a viewing degree less than a predetermined value may be determined, and the format or order of summary information of items that have attribute information similar to or similar to that attribute information may be changed. In this case, the format or order of summary information that has not yet been displayed on the screen may be changed on the condition that a predetermined number or more of detailed information have been displayed. In this way, it is possible to avoid changing the order or format of summary information in the list at a stage where there is little information to determine the user's interests.

[0075] If a user who opens detailed information from a list repeatedly views the detailed information (details tab) and then immediately closes it, it is presumed that the user is not interested in the common parts of the information contained in the multiple detailed information that were quickly closed, especially the part that was displayed immediately before. In such a case, attribute information that is common to the closed detailed information or the information that was last viewed, or that appears frequently, is extracted. Then, it may be determined that the user is not interested in summary information of an item that has attribute information that is the same as or similar to the extracted attribute information, and the appearance or order of the summary information may be changed to make it less noticeable.

[0076] More specifically, if the item is an accommodation facility, and "smoking allowed" or "pets allowed" is displayed in the detailed information and then immediately closed several times, the appearance or order of the summary information in the list may be changed to lower the display priority of the "smoking allowed" and "pets allowed" accommodation facilities. In this way, for example, if a user desires a specific condition such as "pets not allowed" but is unable to search for facilities that specify the specific condition, a list in which the display priority of the specific condition is lowered can be provided to the user, and a useful list can be provided to the user.

[0077] After the format and order of the summary information are determined based on a plurality of attribute information common to a plurality of detailed information that are immediately closed, if it is determined that the user is not interested in a particular attribute information among the plurality of common attribute information according to the browsing status of the detailed information, the format and order of the summary information having the particular attribute information may be changed so as not to stand out. For example, after the format and order of the summary information are determined based on the attribute information of "smoking allowed" and "pets allowed", if it is determined based on the browsing status of the detailed information that the user is interested in only "smoking allowed" but is not interested in "pets allowed", the format and order of the summary information having the attribute information of "smoking allowed" may be changed. That is, each time the browsing of the detailed information from the list is repeated, attribute information that the user is not interested in or is interested in is narrowed down, so the format and order of the summary information may be changed based on the narrowed down attribute information. In this way, as the browsing of the user's list progresses, the list that the user desires can be approached.

[0078] In addition, the change unit 104 of the list providing device 10 may extract attribute information common to a plurality of detailed information displayed on the screen, and when the common attribute information is characteristic of a plurality of items, the order or appearance of the summary information of the items having the common attribute information may be changed. For example, the attribute information may be determined to be characteristic or not depending on whether the ratio of the items having the extracted attribute information to the entire items in the list is equal to or greater than a predetermined ratio or less than a predetermined ratio. In addition, when extracting the common attribute information or determining whether it is characteristic or not, the ratio included in the detailed information that is immediately closed may be taken into consideration for extraction. For example, attribute information common to a specific ratio or more of the detailed information displayed may be extracted, and whether the attribute information is characteristic or not may be determined according to the ratio of the attribute information to the entire information. In this way, the display priority of the summary information in the list is changed based on the characteristic information, so that the list can be provided to the user in a suitable manner. In addition, the display priority of the summary information in the list is not changed based on non-characteristic information, so that it is possible to prevent unnecessary changes in the display priority. For example, if the display priority is changed based on attribute information included in most of the items in the list, there is a risk of unnecessary control. In this way, such unnecessary control can be prevented. Furthermore, when determining whether the extracted common attribute information is characteristic, the change unit 104 may determine that the common attribute information is characteristic if the common attribute information satisfies a predetermined condition. The predetermined condition may be input in advance to the list providing device 10, or may be set by a user or an administrator.

[0079] The change unit 104 of the list providing device 10 may change the display order or format of summary information of items similar to one or more detailed information displayed on the screen after the list is displayed on the screen so that summary information that has not yet been displayed on the screen stands out in the list. In this case, the display order or format of summary information of items similar to detailed information whose browsing degree is equal to or greater than a predetermined value among the detailed information displayed on the screen may be changed so that summary information stands out in the list. In this way, summary information of items that are expected to be useful to the user can be made to stand out, so that a useful list can be provided to the user.

[0080] In the above embodiment, an example of displaying a list and detailed information in a tab browser has been described, but the present invention may also be applied to a browser without tabs (window browser), a dedicated browser, or a dedicated application. In this case, the display areas (windows, etc.) for the list and detailed information may each be configured so that the focus target can be moved.

[0081] For example, when the present invention is applied to a window browser, a list is displayed in one window, and when a link to detailed information of an item in the list is selected, a new window is opened and the detailed information of the selected item is displayed in the new window, and the new window is made active and displayed in the foreground, so that the focus is shifted to the detailed information. After the detailed information window becomes active, when the list window becomes active, the display order or appearance of the summary information included in the pre-scroll portion of the list can be changed according to the similarity with the displayed detailed information and the viewing status of the displayed detailed information.

[0082] Furthermore, when the server 20 provides a list, similarity information between detailed information (for example, similarity information between attribute information of each item, similarity information between first views) may be provided to the list providing device 10. In this way, it becomes unnecessary for the list providing device 10 to calculate the similarity, and the processing speed can be increased.

[0083] The list providing device 10 can be realized by using a normal computer, not a dedicated device. For example, the list providing device 10 that executes the above-mentioned processes may be configured by installing a program for executing the above-mentioned functions on a computer from a recording medium storing the program on the computer. Also, one list providing device 10 may be configured by multiple computers operating in cooperation with each other.

[0084] Furthermore, the method for supplying the program to the computer is arbitrary. For example, the program may be supplied via a communication line, a communication network, a communication system, etc. For example, a non-transitory computer-readable recording medium storing the program for executing the above-mentioned functions may be distributed.

[0085] Furthermore, in the case where an OS (Operating System) provides some of the above-mentioned functions, the functions other than those provided by the OS may be provided by a program.

[0086] The above-described embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The flow charts, sequences, elements included in the embodiments, and their arrangements, materials, conditions, shapes, sizes, etc. are not limited to those illustrated, and can be changed as appropriate. In addition, configurations shown in different embodiments can be partially substituted or combined with each other.
