Any known mechanism can be used for providing these services. Also, the bulletin board service provided by the provision information storage server 600 according to the present embodiment provides a writing service limited to a specific category.

  Next, a processing procedure in the bulletin board service of the provided information storage server 600 as described above will be described. FIG. 8 is a diagram showing a processing flow of the provided information storage device in the information system according to the embodiment of the present invention. In FIG. 8, the description is based on an example in which the writing service (bulletin board service) of the provision information storage server 600 is used from the terminal device 100.

  In FIG. 8, in step S201, the terminal device 100 side inputs an ID, a password, and a category that the user wants to discuss through writing, and the content is transmitted.

When the provided information storage server 600 receives the ID, password, and write category, password authentication is performed in step S202. If there is no problem in the password authentication and authentication is performed in step S203, the process proceeds to step S204, where login to the designated category writing service (bulletin board service) is performed. In the next step S205, processing is performed so that the screen of the writing service (bulletin board service) is displayed on the terminal device 100 side. FIG. 9 is a view showing a screen display example of the designated category writing service (bulletin board service) of the information system according to the embodiment of the present invention. Write service (
The display screen according to the bulletin board service takes the form of a window as shown in the figure, for example. A designated category discussion (in this example, a “ramen store” forum) is displayed at the top of the window screen.

  At the top of the window, a discussion category (in this example, “ramen store”) is clearly indicated. Such discussion categories can be further classified into discussion themes (threads) launched by individual contributors. Each participant can make various statements through writing, and at the same time, can start up a discussion theme (thread) for writing up a discussion on a predetermined theme. In relation to such a discussion theme (thread), other participants can write their opinions or simply browse them.

  In the example shown in FIG. 9, “Ochanomizu New Open Shop” by a participant who owns DHIK8599 as a user ID, “Regarding the Hotness of Ramen N” by a participant who owns YUQIZ32F as a user ID, and KGBC3696 as a user ID. A discussion theme (thread) such as “Super Battle Zone! Ikebukuro Information” by a participant is launched, and the progress information that other participants have written and viewed is shown. . Participants can participate in and view discussions on the theme by clicking on the theme name of the discussion theme (thread), such as “Ochanomizu New Open Shop” with a pointing device. . The total count of clicks from each participant is reflected in the “viewing number”. As for writing in individual discussion themes (threads), the same as the conventionally known bulletin board service can be used.

  In FIG. 9, the “number of replies” column indicates how many entries have been made for the discussion theme (thread) in the bulletin board service, and the “poster” column launches the discussion theme (thread). The “Number of browsing” column indicates the number of participants who viewed the discussion theme (thread), and the “Date” column indicates the discussion theme (thread). It indicates the date and time when it was launched (written). Among these, in particular, the “reply number”, “view number”, and the like are stored and managed on the system side as a reply number counter, a browse number counter, etc. in an unillustrated overall counter.

  In the next step S206, the access counter of the designated category writing service (bulletin board service) is incremented. This access counter counts (stores the number of accesses) the total number of people (IDs) who have accessed the specified category writing service (bulletin board service), and the number of participants who simply refer to the top page of the bulletin board is also counted. include.

In the next step S207, a write counter (personal counter) for each user and each category is activated. A predetermined ID holder counts and stores the number of times of writing in a predetermined category. Further, as the counter of the number of times of writing, the counting is performed by dividing the writing type according to what kind of writing has been performed.

  A specific example of such a write count counter will be described. FIG. 10 is a diagram showing an example of the data structure of the write number counter of the information system according to the embodiment of the present invention. In the example as shown in FIG. 10, the number of times the writing counter is DHIK 8599 as a user ID is a category such as “Professional Baseball”, “Mountain Bike”, “Ramen Shop”, “Hawaii”, “Electronic Craft”, etc. The number of times of writing is counted and stored.

  The write count counter is set to count according to the write type. Specifically, the writing number counter includes (a) writing when the theme is launched (posted), (b) writing on the theme launched by itself, (c) writing on the theme launched by others, The number of writes for each of the three write types is counted and stored.

  In the example shown in FIG. 10, a participant having DHIK8599 launches a discussion theme (thread) five times in the category related to “Ramen shop”, writes 37 times within the discussion theme (thread) launched by himself, In addition, it is counted and stored that the writing was made 44 times in the discussion theme (thread) set up by other participants in the category of “Ramen shop”.

  Returning to the flow of FIG. 8, in step S208, write permission is transmitted to the terminal device 100 side.

  Next, in step S209, the user inputs writing related to the designated category and transmits it to the provided information storage server 600 side on the terminal device 100 side. Subsequently, in step S210, on the provided information storage server 600 side, FIG. The specified category (for example, the category of “ramen store”) of the writing number counter shown in FIG. In step S211, the writing by the user is reflected on the display of the designated category writing service (bulletin board service) as shown in FIG.

  Next, the processing procedure at the time of scoring in the ranking service of the provided information storage server 600 as described above will be described. FIG. 11 is a diagram showing a processing flow at the time of scoring of the provided information storage device in the information system according to the embodiment of the present invention.

  In FIG. 11, in step S301, an ID, a password, and a category that the user wants to rank are input on the terminal device 100 side, and the content is transmitted.

  When the provided information storage server 600 receives the ID, password, and ranking category, password authentication is performed in step S302. If there is no problem in the password authentication and authentication is performed in step S303, the process proceeds to step S304, and the designated category designation category ranking service is logged in. In the next step S305, processing is performed so that the ranking service screen is displayed on the terminal device 100 side.

Such a ranking service allows users to rank items that are classified under a specific category, such as a ramen store, for example, a specific ramen store. This service accepts scoring. FIG. 12 is a diagram showing a screen display example of the category designation category ranking service of the information system according to the embodiment of the present invention. The display screen related to the ranking service takes the form of a window as shown in the figure, for example. The specified specific category (in this example, “ramen store”) is clearly indicated at the top of the window screen. In the window, items that are classified under this specific category (Tokorama “T Ramen”, Akihabara “J Ramen”, etc.) are shown, and the score given by the user is also given. It is written together. Further, when scoring each ramen shop, the user can proceed to a scoring screen by clicking a “scoring” UI with a pointing device (not shown) or the like.

  In step S306, scoring permission is transmitted from the provided information storage server 600 to the terminal device 100 side.

  Next, when the user performs scoring on the items classified into the designated category in step S307 on the terminal device 100 side and transmits them to the provided information storage server 600 side, in step S308, in the ID, A routine for calculating the influence level of the owner in the category is executed. The larger the numerical value of this degree of influence, the more knowledge, insight, etc. of the ID holder with respect to the category, and weighting is performed in the direction in which the scored points increase. A routine for calculating the influence level will be described later.

  In step S309, the score is weighted based on the degree of influence, and in step S310, the score is reflected in the ranking service. As described above, since the scoring from the user who is considered to have a deep knowledge of the predetermined category is weighted in such a manner that the score is increased, the reliability of the information provided by the provided information storage server 600 is increased. Will improve.

  Next, an influence degree calculation process routine will be described. FIG. 13 is a diagram showing a flowchart of a routine for calculating the influence degree of the information system according to the embodiment of the present invention. In this flowchart, an example in which the degree of influence of “Mr. Z” shown in FIG. 7 is obtained will be described as an example. In addition, Mr. Z is assumed to be the owner of the user ID: DHIK8599 in FIGS. 9 and 10. It is assumed that the category for which ranking is to be performed by the ranking service is “ramen store”.

  In FIG. 13, when the influence degree calculation process is started in step S400, the process proceeds to step S401, where the ID of the user who has logged into the ranking service (user ID: DHIK8599) is acquired.

  Next, in step S402, the order d (ni) of the ID is acquired. As described above, since the SNS network is formed by mutual authentication of friendships, the centrality based on the order of the nodes is taken into consideration when calculating the centrality of the network. Since the degree of influence in a specific category is required, the centrality of the network is obtained after narrowing down to the category (community). Taking the example of “Mr. Z”, the order d (ni) = 6.

  In the next step S403, centrality Cd (ni) is calculated. When g is the number of all actors, the centrality Cd (ni) = d (ni) / (g−1) can be obtained. It should be noted that the number of all actors g corresponds to ◯ (number of nodes) in FIG. In the example of FIG. 7, g = 18. Cd (ni) is a value that takes a value from a minimum of 0 to a maximum of 1. In the example of FIG. 7, Cd (ni) = 6/17.

  In the next step S404, the write counter information of the category is acquired from the write count counter in the personal counter. In step S404, information on the entire counter (reply number counter) is also acquired.

  In the next step S405, Ew defined as the degree of influence by speech is calculated by Ew = (Wa + Wb + Wc) / Wt. The total number of writes is the write number. It is the same number as the last number. Here, Wt is the total number of writes in the corresponding category. As shown in FIG. 9, this can be calculated by Wt = (45 + 1) + (27 + 1) + (18 + 1) + (22 + 1) + (11 + 1) +. +1 in each term is the count of the startup thread that is the posting source. In addition, Wa is the number of times of writing when the subject is launched (posted) in the corresponding category, Wb is the number of times of writing in the theme that is launched in the corresponding category, and Wc is launched by another person in the corresponding category. This is the number of times the theme has been written. In the example of “Mr. Z”, Wa = 5, Wb = 37, and Wc = 44.

  In step S406, information on the entire counter (viewing number counter) of the category is acquired.

  In step S407, Ep = Pd / Pt. Pd is defined as the number of browsing by all users for the theme launched by himself, and Pt is defined by the total number of browsing by all users for the theme launched by all users including the theme launched by himself. Is. Therefore, Ep indicates how many themes launched by the user with respect to the total number of browsing viewed by all users, and is defined as the degree of attention by browsing. In the case of FIG. 9, Pt can be obtained by Pt = 2040 + 1905 + 567 + 1230 + 366 +. Further, in the example of “Mr. Z”, Pd == 2040 + 366 +.

  In step S408, the influence degree is calculated by (influence degree) = Cd (ni) × Ew × Ep. In step S409, the process returns.

  Thus, according to the information system of the present invention, the weighting at the time of scoring from the user ID in the ranking service is based on the count number stored in the writing number counter and the count number stored in the browsing number counter. Therefore, it is possible to score more reliably than before. In other words, since more weight is given to the score from the user who is considered to have a deep knowledge for the specific category, it becomes possible to transmit more reliable information.

  Next, an example in which each individual uses the information stored in the provided information storage server 600 as described above will be described. FIG. 14 is a diagram showing a flow of information provision of the information system according to the embodiment of the present invention.

  In FIG. 14, in step S501, the terminal device 100 side inputs ID and password ID information and a category related to information that the user wants to receive, and the content is transmitted. In the next step S502, position information is acquired by the GPS receiver of the terminal device 100.

  The information obtained in step S501 and step S502 is then transmitted to the provided information storage server 600. In step S503, when the provided information storage server 600 receives the ID information, category, and position information, the ID information and category information are transferred to the personal information storage server 500 in the next step S504.

In step S505, personal information stored in the personal interest database 510 and the personal action history database 520 corresponding to the ID is acquired. It is assumed that the data stored in the personal interest level database 510 and the personal action history database 520 are associated with the ID on the provided information storage server 600 side.

  In the next step S506, a proposal order determination routine is executed to determine the proposal order. The information system according to the present embodiment is not intended to make a suggestion or search based on a proposal based on information stored in the personal interest database 510. The information content is not biased or becomes one pattern. The routine for the proposal order determination process will be described later.

  The proposal order information determined in step S506 is transmitted to the provided information storage server 600 side together with the ID information. In the next step S507, when the provision information storage server 600 receives the ID information and the finalized proposal order information, in step S508, a search is executed based on the child category having the finalized proposal order and the position information. In the next step S509, the search result of the provided information storage server 600 is transmitted to the terminal device 100 side.

  On the terminal device 100 side, the search result is received in step S510, and the search result information is displayed on the display 115 in step S511.

  Next, the proposal order determination routine will be described in more detail. FIG. 15 is a view showing a flowchart of a proposal order determination process routine of the information system according to the embodiment of the present invention. An example will be described in which the specific category (parent category) is “restaurant” and the (suggested) ranking of items (child categories) classified below is determined.

In FIG. 15, when the subroutine for the proposal order determination process is started in step S600, the process proceeds to step S601. In step S601, a category (child category) classified under a specific category (parent category). Extract the interest level. Such an interest level extraction method will be described with reference to FIG. FIG. 16 is a diagram for explaining a method of extracting the interest level of a category (child category) classified under a specific category (parent category). Here, logs of all categories (child categories) classified under the restaurant (parent category) are extracted from the personal interest degree database 510. Then, the ranking is performed in the order of categories with the largest total time. This is because the higher the total time, the higher the level of interest. For the degree of interest, the total degree T of each category is used, and for example, in the case of the first category “ramen store”, the degree of interest is calculated as t ₁ / T.

  In the next step S602, an action log relating to a category (child category) classified under a specific category (parent category) is extracted. Such an action log extraction method will be described with reference to FIG. FIG. 17 is a diagram for explaining an action log extraction method for a category (child category) classified under a specific category (parent category). Logs related to all categories (child categories) classified under the restaurant (parent category) are extracted from the personal behavior history database 520. That is, here, a log of (location information) = (restaurant) is extracted. And as shown in FIG. 17, it sorts in an order from the newest thing. In the example shown in FIG. 17, the bottom line is the latest log.

  In the next step S603, category information within a predetermined period from the present is acquired from the log obtained in step S602. In the example of FIG. 17, category information of “ramen store”, “soba / udon store”, and “tonkatsu store” can be obtained by dividing the predetermined period by a pointer as illustrated.

In the next step S604, it is determined whether or not there is a category having the highest degree of interest in the obtained category information. The determination result in step S604 is YES
If YES, the process proceeds to step S605. If NO, the process proceeds to step S606.

  In step S605, the rank of the category with the highest degree of interest is lowered to determine the proposal rank. The explanation is based on the example of a brother. As shown in FIG. 16, “Ramen shop” is the first place of interest determined in step S601, and “Ramen shop” is included in Nakai category information within a predetermined period obtained from the action log in step S603. It is. At this time, the determination in step S604 is YES, and step S605 is performed. In such a case, as shown in FIG. 18, the “Ramen shop” with the highest degree of interest, for example, lowers the rank to the third rank and determines it as the proposal rank. Thus, in this embodiment, since the order of proposal is changed by the action history extraction log, the information content proposed to the user is not biased or becomes one pattern, which is fresh for the user. Proposals can be received.

  Since step S606 is a case where the recent action does not cover the interest level, (suggested rank) = (ranked level of interest determined in step S601). In step S607, the process returns.

  Next, another embodiment in the case of using information stored in the provided information storage server 600 as described above will be described. FIG. 19 is a diagram showing a flow of information provision of an information system according to another embodiment of the present invention. In the embodiment shown in FIG. 14, the user inputs a category and transmits the category to the provided information storage server 600. However, in the present embodiment, the provided information storage server 600 automatically executes the flow. The information is searched after the category is extracted. For this reason, the present embodiment includes a category automatic extraction processing subroutine in step S704. In accordance with this, the step of inputting a category by user input is omitted.

  Hereinafter, the subroutine of the category automatic extraction process will be described in detail. FIG. 20 is a view showing a flowchart of a subroutine of automatic category extraction processing of the information system according to the embodiment of the present invention.

  In FIG. 20, when the category automatic extraction process is started in step S800, the position information transmitted from the terminal device 100 is acquired in step S801. Next, in step S802, time information is acquired from a time measuring unit (not shown).

  In step S803, it is determined whether the acquired position information is a registered place such as a home. Although the registration location is not limited to the home, here, the registration location is assumed to be the home. If the determination in step S803 is YES, the process proceeds to step S804, and if NO, the process proceeds to step S808.

  Next, in step S804, it is determined whether or not the acquired time information is a specific time. Here, the specific time will be described. FIG. 21 is a diagram for explaining a specific time in an information system according to another embodiment of the present invention. The specific time is usually a time when a person performs a related act of eating. For example, as shown in FIG. 21, it is 6:00 to 8:00, 11: 00 to 13:00, 18: 00 to 20:00. A time zone is defined.

  In step S805, since the meal time is searched at home, the search category is set as “recipe”, and the process returns in step S811.

In step S806, which proceeds when the determination in step S804 is NO, the interest level is calculated from the entire interest information log. Here, the calculation of the interest level in step S804 will be described. FIG. 22 is a diagram for explaining a method of calculating the interest level of a category classified under all the interest levels.

In order to calculate the interest level of the categories classified under all the interest levels, information is extracted from the personal interest level database 510. At this time, as shown in FIG. Is done. This is because the higher the total time, the higher the level of interest. As for the degree of interest, the total degree T of each category is used to calculate the degree of interest as t _a / T in the case of the first category “professional baseball”, for example.

  In step S807, (category) = (category of highest interest level). In the example of FIG. 22, “professional baseball” is set as the category for search.

  In step S808 that proceeds when the position information is outside the home, it is determined whether or not time = specific time. When the determination result is YES, the process proceeds to step S809, and when it is NO, the process proceeds to step S810.

  In step S809, since it is a meal time zone when going out, “restaurant” is set as a category and is used for search. In step S811, the process returns to the main routine.

  In step S810, a regional key category is set as the category. Here, the regional key categories will be described. FIG. 23 is a diagram showing a regional key category table used in an information system according to another embodiment of the present invention. A category peculiar to each region is stored in a suitable storage means as a table as shown in FIG. 23 as a key category for each region. In step S811, which region in FIG. 23 corresponds to is determined from the acquired position information, and a category for each region is selected accordingly. For example, when the terminal device 100 is present in the A area based on the position information from the terminal device 100, the category is set to “fashion” and a search is performed. In step S811, the process returns to the original routine.

  According to the other embodiments as described above, the search is performed based on the category that is considered suitable for the user according to the time zone and the place, so that the user can save input.
