  However, in the system described in Patent Document 1, since a book (content) is recommended regardless of the user's state, the user cannot confirm information at the time of recommendation or is in a state not suitable for purchase. In some cases, even if a book is recommended, it may not lead to purchase, and it cannot be said that the function as an advertisement is fully exhibited.

  Further, since the system described in Patent Document 2 is configured to provide guidance to the user at a bookstore in the real world, when the user is outside the bookstore, the book cannot be recommended and the place of use is limited. It will be.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a server system or the like that can provide appropriate recommendation information in consideration of the state of the user.

  (1) In order to solve the above-described problem, a server system according to the present invention is a server system that provides information related to content as recommended information to a communication terminal device connected via a network, and identifies the content. A first management unit that manages a first recording unit that records the content ID as content information in association with the content attribute information indicating the content attribute corresponding to the content ID, and the communication A second recording unit that manages the user ID for identifying the user of the terminal device and the content ID corresponding to the purchased or read content of the user in association with each other and is recorded as content history information is managed. From the second management means and the communication terminal device, the current position of the communication terminal device at predetermined time intervals. While associating the location information to be shown and the user ID corresponding to the user of the communication terminal device, the acquisition means to acquire and the facility ID for identifying various facilities existing in the real world, Third management for managing the third recording means for recording the range information indicating the range including the existing position in the real world and the facility attribute information indicating the attribute of the facility as facility information in association with each other Means, estimating means for estimating a user state of the communication terminal device at the acquisition date and time of the position information based on the acquired position information and the range information, the estimated user state, and the first Based on the content information recorded in the recording means and the content history information recorded in the second recording means, a recommendation target content to be recommended to the corresponding user is determined. Determining means, based on the content attribute information corresponding to the recommended target content the determined, to generate the recommendation information, and has a structure that comprises a providing means for distributing the corresponding communication terminal apparatus.

  For example, while moving on a train, analog content such as paper books cannot be purchased and only digital content such as electronic books can be purchased. Advertising effects are higher when advertising analog content such as books sold in the case of existing stores in the world. In addition, while users are more likely to purchase content while traveling, they purchase content when they are staying in a specific facility except for stores that sell analog content, such as during work or during classes. There is almost no opportunity.

  With this configuration, the server system of the present invention estimates, for example, that a user such as a specific facility exists in the facility, the user's movement state such as walking or train movement, and the user's state such as at work or during class. For example, an electronic content sale advertisement is provided while moving on a train, and analog content provided at the content sale facility while walking around the content providing facility is sold. It is possible to change recommendation information such as an advertisement distributed according to the user state, such as an advertisement.

  Therefore, the server system of the present invention can provide the recommended information suitable for the user's condition, such as being able to maximize the advertising effect, and can improve the convenience for the user. .

If you are staying at a sales facility that sells analog content, provide recommended information that is appropriate for the user's status, such as providing recommended information about analog content sold at the facility. Can do.

  (4) Further, in the server system of the present invention, the facility information is stored in association with a stop location of public transportation and a line of each line existing in the real world, and the estimation means includes the Based on the position information and the range information, it is estimated whether the user is in a moving state in which a specific public transport is traveling on a vehicle operated on any route, When it is estimated that the mobile device is in a moving state, the determining unit is configured to digitally calculate based on the content information recorded in the first recording unit and the content history information recorded in the second recording unit. The content is determined as the recommendation target content.

  With this configuration, the server system according to the present invention is digitally recorded as the target content, assuming that the content existing in the real world cannot be purchased when it is estimated that the user is in a moving state using a public transportation vehicle. Since the content can be recommended, recommendation information suitable for the user's condition can be provided accurately.

  (5) Further, the server system of the present invention is associated with the content ID and a stop and a route of public transportation existing in the real world, and in the real world where the corresponding analog content can be purchased. The apparatus further includes a fourth management unit that manages a fourth recording unit that stores store information related to the store, and when the movement state is estimated, the determination unit is recorded in the first recording unit. Based on the stored content information and the content history information recorded in the second recording means, the store information of the stores existing in the travel route of the corresponding user is specified and recorded in the first recording means. Based on the stored content information, the content history information recorded in the second recording means, and the specified store information, Serial determined as a recommended target content, has a structure.

  With this configuration, when it is estimated that the user is in a moving state, the server system of the present invention can provide recommendation information for analog content based on a store existing near the stop location of the user's planned travel route. Since it can be provided, it is possible to recommend analog content that can be purchased at an actual store even in a state where the analog content cannot be purchased at the actual store, so that convenience for the user can be improved. .

  (6) In the server system of the present invention, the current position of the communication terminal device indicated by the acquired position information is within a real world range where the store indicated by the store information exists. If the estimation means estimates that the user is in the store entering the store and the store enters the store, the store can be purchased at the store in the store The analog content is determined as the recommendation target content.

This is data to be displayed as a cover of a book, and is used to display a sample of a book selected by a user based on recommendation information.

  The electronic book data is data for displaying the electronic book on the communication terminal device 10, and when the corresponding electronic book has not been issued, the electronic book data is not stored in the field, and is illustrated in FIG. As such, data “paper books only” is stored.

  In addition, although the example which stores electronic book data in book management DB302 was shown in FIG. 5, you may record electronic book data matched with book ID in another DB. In this case, a field for storing a flag indicating whether or not it is only a paper book may be provided in the book management DB 302, and the presence or absence of an electronic book may be determined based on the flag.

  For example, in FIG. 5, books corresponding to the book IDs “B101”, “B102”, “B103”, and “B104” belong to the “novel” category, and “B101” and “B102” are “suspense”, An example is shown in the case where it belongs to “Mystery novel”, and “B103” and “B104” belong to “Fantasy” and “Adventure”. FIG. 5 shows a state in which the title, price, number of sales, etc. of the book corresponding to each book ID are stored.

  Note that various information records in the book management DB 302 may be registered by the administrator of the management server device 30 at the time of publication of the book using an operator terminal device (not shown).

The purchase history DB 303 is a DB in which information (hereinafter referred to as “purchase history information”) for managing the history of each user purchasing an electronic book or a paper book is recorded as data. For example, the purchase history DB 303 is associated with each user ID as shown in FIG.
(1) a book ID corresponding to a book that the user has purchased;
(2) Date and time of purchase
(3) the medium type (electronic book or paper book) of the book purchased by the user;
Is used when the recommended book is determined in the recommended book determination process.

  For example, FIG. 6 shows a state where purchase history information is recorded when a user corresponding to “U001” purchases a book corresponding to book IDs “B101”, “B105”, and “B200”. Yes.

  In addition, when the user purchases an electronic book at an electronic bookstore, the information regarding the purchase history DB 303 is determined by the timer 330 by specifying the purchase date and time and determining the medium type as “electronic book”. It records in purchase history DB303 with book ID etc. of the said purchased book.

  Further, when a user purchases a book at a real store (bookstore) S, purchase history information is recorded in the purchase history DB 303 based on the user ID and information related to the book transmitted by the bookstore terminal device 20. In this case, the purchase date and time may be specified in the bookstore terminal device 20 and transmitted together with the user ID. However, the information regarding the book transmitted from the bookstore terminal device 20 may include a book ID or may include a book title.

  Furthermore, when information including the title of a book is transmitted from the bookstore terminal device 20, the book ID may be searched from the book management DB 302 and included in the purchase history information. In this case, the medium type is determined as “paper book”. The information transmitted from the bookstore terminal device 20 may include, for example, a book name.

The author management DB 304 is a DB in which information for managing the author of a book is recorded as data. For example, in the author management DB 304, as shown in FIG.

  Note that each route includes a route (for example, a track or a road) followed by the route in addition to a stop location such as a station on the route, and therefore, in this embodiment, as shown in FIG. As described above, the route range information of the relevant transportation is recorded in association with each route ID.

  In this embodiment, in order to simplify the information management, the transportation management DB 305 is divided into two as shown in FIGS. 8A and 8B. However, the transportation management DB 305 is recorded in the transportation management DB 305. The data to be stored is not limited to this, and may be combined into one.

  Furthermore, the station range information and the route range information are information indicating the location of the station in the real world and information indicating the location of the route, respectively.

  Since the actual station and route exist in the real world in a state having a corresponding spread (area or volume), the station range information and the route range information are the actual station or route route. It is necessary to make it possible to specify that the user is in a station premises or in a state of getting on a transportation facility.

  For this reason, in FIG. 8, the station or route is surrounded by the coordinates of four points to express the station range information and the route range information. In the case of the example shown in FIG. An example is shown in which the station range information of “XX line” and “Station A (starting point)” is latitudes “N36.2644211 to N36.624755” and longitudes “W138.72344478 to W1388.7234656”. Yes.

(2) Inventory information,
Is recorded.

  The bookstore information includes the bookstore name and bookstore range information of the corresponding actual store (bookstore) S, and is used to specify the actual store (bookstore) S that the user has visited. The inventory information is configured to include the book ID and the inventory quantity of each book in order to manage the inventory quantity of the book in each actual store (bookstore) S, and can be purchased at the actual store (bookstore) S. Used to identify a book.

  For example, FIG. 9 shows a recording example in which “XX bookstore” corresponding to the bookstore ID “S001” exists in the range of “N36.624619-N36.62444721, W1388.72344411-W1388.7234615”. Has been.

  The bookstore range information is information indicating the location of the corresponding actual store (bookstore) S as in the case of the station range information and route range information, and the user enters the actual store (bookstore) S based on the position information of the user. It is used to specify whether or not In addition, the detail of bookstore range information in this embodiment is mentioned later with station range information and route range information.

  The user state management DB 307 is a DB in which information for estimating the user state is recorded as data based on the position information acquired from the communication terminal device 10. For example, in the user state management DB 307, as shown in FIG. 10, the state name of the state and determination requirement information are recorded in association with the user state ID for identifying the user state.

In this user state, at least (A) “provisional standby”
(B) “Standby”
(C) “Start moving”
(D) "Moving temporary train"
(E) "Train movement"
(F) "Entering the store"
6 states are defined in advance, and the determination requirement information indicates necessary conditions for estimating each state.

  In particular, the temporary standby state of the present embodiment indicates a case in which none of the standby, temporary train movement, and train movement is applicable, and indicates a state before the user shifts to some state.

  The standby state of the present embodiment is, for example, a case where it is estimated that the standby state indicates that the user is at work or in class. Specifically, the immediately preceding user action is a temporary standby state, and the user's movement A case where the distance is within a predetermined distance (for example, 150 m) is shown. In this embodiment, the moving distance is set to 150 m or less based on twice the maximum position information error of 50 m and the added value of the distance 50 m that the user is likely to move on foot in one minute. ing.

  The movement start state of the present embodiment indicates a state when the user starts moving when the immediately preceding user action is in a standby state and the current user action is in a temporary standby state.

Temporary train movement status indicates the stage before the user uses transportation,
(Requirement A) When the immediately preceding user behavior is not in the temporary train moving state, and the current user position is within the route range or the station range, and
(Requirement B) When the previous user action is a temporary train moving state, the current user position is within the route range or the station range, and the displacement amount of the user position is equal to or less than a predetermined threshold value,
If any of the requirements are met.

  The train movement state indicates a state in which the user is moving using transportation, the previous user action is a temporary train movement state, the current user position is within the route range or the station range, and the user position A case where the displacement amount is equal to or greater than a predetermined threshold value (for example, approximately 3 km or more when the transportation facility moves at 40 km / h and the position information transmission interval is 5 minutes) is shown.

  The store entry state indicates that the user has entered the actual store (bookstore) S, the immediately preceding user behavior is the start of movement or the train movement state, and the current user position is within the store range. .

The template DB 308 is a DB for managing template data corresponding to a template of recommendation information used when generating recommendation information. For example, as shown in FIG.
(1) a template ID for identifying each template data;
(2) the state of the user to which the template data should be applied;
(3) a template data body;
Are recorded in association with each other.

  Note that this template data includes texts that differ for each user state, and recommendation information is generated based on the book attribute information of the recommendation target book and the template data.

  The server management control unit 340 is mainly configured by a central processing unit (CPU), and integrally controls each unit of the management server device 30 by executing a program.

  The data processing unit 350 is configured by an independent central processing unit (CPU) or by using the central processing unit (CPU) of the server management control unit 340. Then, the data processing unit 350 executes a program under the control of the server management control unit 340, thereby acquiring a location information from the DB management control unit 351 that manages each of the DBs 301 to 304 and the communication terminal device 10. An information acquisition unit 352, a user state estimation unit 353 that executes user state estimation processing, a recommended book identification unit 354 that executes recommended book determination processing, a recommended information generation distribution unit 355 that generates and distributes recommendation information, An electronic book store 356 that manages and manages the electronic bookstore and distributes the electronic terminal data of the communication terminal device 10 is realized.

  For example, the DB management control unit 351 of the present embodiment constitutes the first to fourth management means of the present invention, and includes a position information acquisition unit 352, a user state estimation unit 353, a recommended book specifying unit 354, and a recommended book. The specifying unit 354 and the recommendation information generation / distribution unit 355 constitute an acquisition unit, an estimation unit, a determination unit, and a provision unit of the present invention.

  The DB management control unit 351 performs various controls for managing the reading and writing of data with respect to each DB.

  Specifically, when the location information acquisition unit 352 acquires location information from the communication terminal device 10, the DB management control unit 351 stores the location information in the user management DB 301 in conjunction with the location information acquisition unit 352. To do.

  Further, when the DB management control unit 351 acquires the user ID transmitted from the bookstore terminal device 20 and information on the book purchased by the user, the DB management control unit 351 generates purchase history information based on the received information, and the generated purchase history Information is registered or updated in the purchase history management DB 303, and the inventory number of the corresponding book is subtracted from the inventory information of the actual store (bookstore) S where the bookstore terminal device 20 is installed with respect to the actual store management DB306. The inventory information in the actual store management DB 306 is updated.

  The user state estimation unit 353 is based on the current location information acquired by the location information acquisition unit 352 and recorded in the user management DB 301 and the previous location information recorded in the user management DB 301. The moving speed of the user is calculated, and the moving speed of the user is calculated based on the moving distance based on the position information acquisition interval.

  In addition, the user state estimation unit 353 executes a user state estimation process for specifying the user state based on the calculated moving distance and moving speed and the determination requirement information for each state recorded in the user state management DB 307. To do. Details of the user state estimation process in the present embodiment will be described later.

  The recommended book specifying unit 354 executes a recommended book determination process for determining a book to be recommended according to the state of the user.

  Specifically, the recommended book specifying unit 354 determines a book that can be purchased as a recommended book at an actual store (bookstore) S where the user is staying when the user state is in the store state, When the user state is in a state other than the store entry state, an electronic book or a book that can be purchased at an actual store (bookstore) S nearest to the user is determined as a recommended book.

  The recommendation information generation / distribution unit 355 searches the template DB 308 based on the user state estimated by the user state estimation unit 353, and reads template data to be used in the state. Then, the recommended information generation / distribution unit 355 reads the book attribute information and the cover sample data corresponding to the book determined by the recommended book specifying unit 354, and generates recommendation information while embedding it in the template data.

  In addition, when the recommendation information generation / distribution unit 355 generates the recommendation information, the recommendation information generation / distribution unit 355 describes the generated recommendation information in an e-mail in, for example, an XML or HTML (HyperText Markup Language) format, and also describes the e-mail in the user information. Deliver to the email address included in.

  The recommendation information distribution method is arbitrary. For example, the communication terminal is a push-type or pseudo-push method (a method of inquiring from the communication terminal device 10 every predetermined time and distributing recommendation information). You may make it deliver to the apparatus 10. FIG.

  The electronic book sales unit 356 performs various processes for managing and operating a book sales site in an electronic bookstore. In particular, when a user purchases an electronic book at an electronic bookstore, the electronic book sales unit 356 distributes electronic book data corresponding to the electronic book and records purchase history information in the purchase history management DB 303.

[3] Range Information Next, station range information, route range information, and bookstore range information recorded in the transport management DB 305 and the actual store management DB 306 in this embodiment will be described with reference to FIG. FIG. 12 is a conceptual diagram for explaining the range information of the present embodiment. In FIG. 12, the station range information for the stations existing in the real world is shown as an example. The bookstore range information is the same except that the facility indicated in the information is a route route or an actual store (bookstore) S, and since it has the same format, in the following, the station range information will be described as an example. To do.

  As shown in FIG. 12, the station range information of the present embodiment is surrounded by coordinate points (for example, four points) surrounding the range where the station exists on the map of the real world, and as shown in FIG. 8 (A). , Indicated by the data format of latitude range and longitude range.

  For example, in FIG. 8A, “N36.26444621 to N36.624644755, W138.72344478 to W1388.7234456” are set as the station range information of “prefectural XX” and “A station”. FIG. 12 shows an example in which this station range information is displayed together with a map of the vicinity of the corresponding station in the real world.

  In addition, FIG. 12 illustrates the format for expressing the station range information at four coordinate points surrounding the station existing area in order to facilitate the creation of information. For example, the range information is detailed by combining a plurality of rectangles. Can be defined. In this case, the range information is expressed by latitude and longitude corresponding to each coordinate such as (coordinate A: coordinate B: coordinate C: coordinate D, coordinate α: coordinate β: coordinate γ: coordinate δ). Also good.

  Further, it may be specified in a CSV (comma-separated value) format.

  In addition to the above, regarding the route range, the position of the road that hits the train or train track or bus route may be expressed in the form of CSV, etc. You may make it express a position.

[4] Operation of Book Recommendation System [4.1] Operation of Book Recommendation System Next, processing executed in the book recommendation system 1 of the present embodiment will be described using FIG. FIG. 13 is a flowchart showing an overall operation when book recommendation is performed in the book recommendation system 1 of the present embodiment.

  In this operation, it is assumed that the user information and the like have been registered by the user. In addition, the user has already purchased several electronic books or paper books, and the information illustrated in FIGS. 4 to 11 is already recorded in the DBs 301 to 308 of the management server device 30. It shall be.

  Further, in this operation, the communication terminal apparatus 10 is in a state where a user ID and a login password corresponding to the user of the own apparatus have been recorded, and to provide recommendation information provided by the management server apparatus 30. It is assumed that the user is logged in to the service, and is in a state of waiting for arrival of position information transmission timing.

  First, when the communication terminal apparatus 10 detects the transmission timing (step Sa101), the communication terminal apparatus 10 detects position information based on the GPS signal transmitted from the GPS satellite 50 (step Sa102), and uses the detected position information as the management server apparatus 30. To shift to the reception standby state (step Sa103).

  Next, in the management server device 30, when the location information acquisition unit 352 receives the location information transmitted from the communication terminal device 10 (step Sa301), the location information acquisition unit 352 is received by the communication control unit 310 in conjunction with the DB management control unit 351. The location information and the like are recorded in association with the corresponding user IDs in the ROM / RAM 320 and the user management DB 301 (step Sa302), and the user state estimation unit 353 executes user state estimation processing based on the received location information. (Step Sa303). Details of the user state estimation process in the present embodiment will be described later.

  Next, the user state estimation unit 353 determines whether or not the user state estimated by the process of step S203 corresponds to any of “movement start”, “train movement”, and “entrance”, that is, a specific user state Is determined (step Sa304).

  At this time, if it is determined that the user state estimation unit 353 does not correspond to any of the states of “movement start”, “train movement”, and “entrance”, this operation is performed without distributing recommendation information. When it is determined that it corresponds to any state, the recommended book specifying unit 354 executes a recommended book specifying process to determine a recommended book (step Sa305). Details of the recommended book specifying process in the present embodiment will be described later.

  Next, the recommendation information generation / distribution unit 355 generates recommendation information by executing a recommendation information generation process (step Sa306), and transmits the generated recommendation information to the corresponding communication terminal device 10 (step Sa307). Note that the recommendation information generation / distribution unit 355 shifts to a state in which it is determined whether or not an electronic book purchase request has been received from the communication terminal device 10.

  Specifically, in the process of step Sa307, the recommendation information generation / distribution unit 355 reads template data corresponding to the estimated user state from the template DB 308, and reads the book attribute information and the cover sample data of the identified book. The recommendation information is generated while reading and embedding the book attribute information and the like in the template data.

  At this time, when the determined book includes an electronic book, the recommendation information generation / distribution unit 355 embeds a URL for purchasing the electronic book in the recommendation information.

  Furthermore, at this time, when the recommended book is a paper book, the recommended information generation / distribution unit 355 reads the book store information of the actual store (book store) S where the book can be purchased, and corresponds to the corresponding book information. At the same time, the recommendation information is generated by embedding it in the template data. Details of the recommendation information of this embodiment will be described later.

  Next, when receiving the recommendation information transmitted from the management server device 30 (step Sa104), the communication terminal device 10 displays the received recommendation information so that the user can view it, and selects any book included in the recommendation information. Shifts to a state of waiting for the input of the user to perform (step Sa105).

  Next, when the communication terminal device 10 selects the purchase of a desired book (step Sa106), the communication terminal device 10 determines whether or not the selected book is an electronic book (step Sa107). At this time, for example, the communication terminal device 10 determines whether the electronic book is based on whether the URL for purchasing the electronic book is embedded in the recommendation information.

  Next, when the selected book is not an electronic book, the communication terminal device 10 can refer to the book attribute information of the selected book and the relevant book so that the book can be referred to when purchasing at the actual store (bookstore) S later. The bookstore information associated with the book attribute information is extracted and recorded as selected book information in the communication terminal device 10 (step Sa108), and this operation is terminated.

  As a result, the user can go to the actual store (bookstore) S while visually recognizing the bookstore information, and purchase a book while referring to the book attribute information recorded in the communication terminal device 10. Become.

  On the other hand, when the communication terminal device 10 determines that the selected book is an electronic book, the communication terminal device 10 transmits a book purchase request including the URL to the management server device 30 and shifts to a reception standby state (step Sa109).

  Note that the communication terminal device 10 may end this operation without sending a book purchase request at this time. However, the communication terminal device 10 can also store a book purchase request including a URL inside the communication terminal device 10 and transmit the book purchase request at an arbitrary timing such as after the end of the operation. It has the structure which can do.

  Next, the electronic book sales unit 356 determines whether or not the electronic book purchase request transmitted from the communication terminal device 10 has been received (step Sa308), and until time-out (step Sa309), the steps of steps Sa308 and Sa309 are performed. Repeat the process. At this time, the electronic book sales unit 356 ends the operation when detecting that a time-out has occurred.

  Next, in the management server device 30, when the communication control unit 310 receives the purchase request (step Sa308), the electronic book sales unit 356 reads the electronic book data from the book management DB 302 based on the URL included in the request, This is distributed to the corresponding communication terminal device 10 (step Sa310), and this operation is terminated.

  Note that when the electronic book sales unit 356 receives an electronic book purchase request from the communication terminal device 10 at an arbitrary timing even after the end of this operation, the electronic book sales unit 356 includes the URL included in the request. The electronic book data is read out from the book management DB 302 and distributed to the corresponding communication terminal device 10.

  Next, when receiving the electronic book data distributed from the management server device 30 (step Sa110), the communication terminal device 10 records the received electronic book data therein (step Sa111), and ends this operation.

[4.2] User State Estimation Process Next, the operation of the user state estimation process executed in the user state estimation unit 353 of the management server device 30 of this embodiment will be described. FIG. 14 is a flowchart showing the user state estimation process.

  This operation is each process executed in the user state estimation process in step Sa303 in FIG. In addition, it is assumed that the information illustrated in FIGS. 4 to 11 is already stored in each DB 301 to 308 of the management server device 30.

  First, the user state estimation unit 353, in conjunction with the DB management control unit 351, reads the location information immediately before the user recorded in the user management DB 301 and the user state immediately before recorded in the user management DB 301 ( Step Sb301).

  Next, the user state estimation unit 353 works in conjunction with the DB management control unit 351 to read determination requirement information from the user state management DB 307 (step Sb302), and from the transport management DB 305, station range information and route range information, and bookstore management The bookstore range information is read from the DB 306 (step Sb303).

  Next, the user state estimation unit 353 calculates the movement distance of the user based on the position information recorded in the ROM / RAM 320 and the position information immediately before the read user (step Sb304), and the calculated movement distance, Based on the read determination requirement information, user status, station range information, route range information, and bookstore range information, it is determined whether or not the user is in a standby state (step Sb305).

  At this time, the user state estimation unit 353 determines that the immediately preceding user action is in the temporary standby state and the moving distance is within 150 m (steps Sb305 and 306), and the process proceeds to step Sb317. Let

  On the other hand, when the user state estimation unit 353 determines that the determination requirement is not satisfied (step Sb305 “no”), the user state estimation unit 353 determines whether the user is in the temporary train movement state (step Sb307). .

  At this time, as the requirement A, the user state estimation unit 353 determines that the immediately preceding user action is not in the temporary train moving state and the current user position is within the route range or the station range, or as the requirement B Whether or not the user behavior in the temporary train movement state satisfies the requirement that the current user position is within the route range or the station range and that the displacement amount of the user position is equal to or less than a predetermined threshold It is determined whether or not the user is in the temporary train movement state (step Sb307).

  If the user state estimation unit 353 determines that the requirement A or B is satisfied, the user state estimation unit 353 determines that the provisional train is moving (step Sb308) and proceeds to the process of step Sb318 and determines that none of the requirements is satisfied. In this case, the user's moving speed is calculated based on the user's moving distance and the position information acquisition interval (step Sb309), and it is determined whether or not the user is in a movement start state (step Sb310).

  Specifically, the user state estimation unit 353 determines whether or not the immediately preceding user action is in a standby state and the current user action is in a temporary standby state, and if it is determined that these requirements are satisfied Then, it is determined as a movement start state (step Sb311), and the process proceeds to step Sb318. When it is determined that these requirements are not satisfied, it is determined whether or not the user is in a train movement state (step Sb312). ).

  Further, when determining whether or not the user is in the train movement state, the user state estimation unit 353 determines that the previous user action is the temporary train movement state and the current user position is within the route range or the station range. In addition, it is determined whether or not the displacement amount (movement distance) of the user position is greater than or equal to a predetermined threshold (for example, about 2.9 km or more) or the movement speed is greater than or equal to a threshold (for example, 40 km / h). If it is determined that the requirement is satisfied, it is determined that the user is in a train moving state (step Sb313), and the process proceeds to step Sb318.

  On the other hand, if the user state estimation unit 353 determines that these requirements are not satisfied, the user state estimation unit 353 reads the bookstore range information from the bookstore management DB 306 (step Sb314) and determines whether the user is in the store entry state (step Sb314). Step Sb315).

  At this time, in order to determine whether or not the user state estimation unit 353 is in the store entry state, the immediately preceding user action is the start of movement or the train movement state, and the current user position is the actual store (bookstore) S If it is determined whether or not it is within the range, and it is determined that these requirements are satisfied, it is determined that the user is in the store entry state (step Sb316), and the process proceeds to step Sb317.

  If the user state estimation unit 353 determines that the user is not in the store entry state, the user state estimation unit 353 determines that the user state is a temporary standby state (step Sb317), and works in conjunction with the DB management control unit 351. Then, the user management DB 301 is updated (step Sb318), and this operation is terminated.

[4.3] Example of State Transition of User State Next, an example of state transition of the user movement state according to the present embodiment will be described with reference to FIG. FIG. 15 is a diagram illustrating an example of state transition of the user state according to the present embodiment.

For example, when carrying out the user state estimation process for the user A in the state transition approaching the vicinity of the transportation line from home or the like and walking along the line,
(1) First, when moving from the temporary standby state to the place corresponding to the station range information or the route range information on foot, the state moves to the temporary train moving state.
(2) And while moving within the route range on foot, the moving distance or moving speed is below the threshold value, so the temporary train moving state is maintained.

On the other hand, the user arrives at the nearest station of the company by train, engages in work after arriving at the company, leaves the company at the time of return, moves to the nearest station, and then enters the train at the state transition. When the user state estimation process is performed on B,
(1) First, when you get off the train from the train, and you are inside the station,
(2) Then, when you arrive at the company, to get out of the station area, transition to a temporary standby state,
(3) After that, when you go to the desk and the position changes, the standby state is entered and the standby state continues until you leave the office.
(4) Next, when the user moves to leave the company, the state shifts to a movement start state.
(5) After entering the temporary standby state until it arrives at the station, when it arrives at the station, it enters the temporary train movement state, and when user B starts to move on the train, it shifts to the train movement state. It will be.

[4.4] Recommended Book Determination Process Next, the recommended book determination process executed by the recommended book specifying unit 354 of the present embodiment will be described with reference to FIG. FIG. 16 is a flowchart showing a recommended book determination process executed by the recommended book specifying unit 354 of the present embodiment.

  This operation is each process executed in the recommended book determination process in step Sa305 in FIG. Further, it is assumed that the information illustrated in FIGS. 4 to 11 is already stored in each DB 301 to 308 of the management server device 30.

  First, the recommended book specifying unit 354 searches the purchase history DB 303 based on the user ID transmitted from the communication terminal device 10 and recorded in the ROM / RAM 320, reads out the purchase history information of the user, and records it in the ROM / RAM 320. (Step Sc300).

  Next, the recommended book specifying unit 354 searches the book management DB 302 based on the book ID of the purchased book, reads the author ID and series name of the purchased book, and searches the author management DB 304 to search for the author. The series names of other series that have been written are read out and recorded in the ROM / RAM 320 (step Sc301), and the author's book or a book that belongs to the same series and has not been purchased by the user. Is searched from the book management DB 302 (step Sc302).

  Next, the recommended book specifying unit 354 detects a medium type with a large number of purchases by the user based on the purchase history information, and the user selects an electronic book based on the medium type (analog or digital) with the large number of purchases detected. (Step Sc303). At this time, the recommended book specifying unit 354 determines whether or not the user prefers an electronic book by regarding the medium type that is frequently purchased by the user as being consistent with the user's preference.

  Next, when the recommended book specifying unit 354 determines in step Sc303 that the user prefers a digital medium, that is, an electronic book, the recommended book specifying unit 354 determines whether there is an electronic book corresponding to the searched book based on the book management DB 302. Determination is made (step Sc304).

  At this time, when it is determined that the corresponding electronic book exists, the recommended book specifying unit 354 determines the electronic book as a recommended book (step Sc305), ends the processing, and does not have the corresponding electronic book. If it is determined, the process proceeds to step Sc308.

  Next, when the recommended book specifying unit 354 determines that the user prefers an analog medium, that is, a paper book, the recommended book specifying unit 354 determines whether or not the user is in the shop entry state (step Sc306) and is not in the shop entry state. If it is determined, the process shifts to step Sc308, and if the user determines that it is in the store entry state, the inventory information of the actual store (bookstore) S that is entering the store is read (step Sc307), and the process shifts to step Sc310.

  Next, when the recommended book specifying unit 354 determines in the process of step Sc306 that the user is not in the store state, the current position information of the user, the bookstore range information recorded in the actual store management DB 306, Based on the above, the nearest real store (bookstore) S is searched from the current position of the user (step Sc308).

  Next, the recommended book specifying unit 354 reads inventory information of the corresponding actual store (bookstore) S by the search (step Sc309).

  Next, the recommended book identification unit 354 is based on the inventory information of the actual store (bookstore) where the user has entered by the process of step Sc307 or the inventory information of the nearest actual store (bookstore) of the user by the process of step S309, It is determined whether or not there is a stock of the book searched in step Sc302 (step Sc311).

  At this time, when the recommended book specifying unit 354 determines that there is a stock of the corresponding book, the recommended book specifying unit 354 determines the book as a recommended book (step Sc312), ends the operation, and the stock of the corresponding book is available. If it is determined that it does not exist, the category with the highest purchase frequency of the user is identified based on the purchase history information and the book attribute information, and the most popular book in the category (the book with the most sales) is determined as the recommended book (Step Sc314), and this operation ends.

By executing the above recommended book determination process, the recommended book specifying unit 354
(1) When an electronic book is a user's preference and there is a corresponding electronic book, the user is a book that has not been purchased and is written by the same author, or other books belonging to the same series The electronic book corresponding to the book is decided as the recommended book,
(2) When the user is in the store, the book is a book that can be purchased at the actual store (bookstore) S in which the user has entered the store, and the user has not purchased the same book as the author, etc. And
(3) When there is no electronic book or when the user is not in the store, it is a book that can be purchased at the actual store (bookstore) S nearest to the user, and the user has not purchased the book but is the same as the author Is determined as a recommended book.

  Thus, based on the determined recommended book, the processing after step Sa306 is executed, and recommendation information is generated and distributed. At this time, the recommendation information generated and distributed is configured to include book attribute information and cover sample data on a template corresponding to the user state, as illustrated in FIG.

  As described above, in the book recommendation system 1 of the present embodiment, a user such as a specific facility is present in the facility, the user's movement state such as walking or moving on the train, the user during work or class, etc. For example, an electronic content sales advertisement is provided while the train is moving, and the analog content provided at the content sales facility while moving around the content providing facility on foot. It is possible to change recommendation information such as advertisements distributed according to the user state, such as selling advertisements for various contents.

  Therefore, in the book recommendation system 1 of the present embodiment, it is possible to accurately provide recommendation information suitable for the user's condition, such as being able to maximize the advertising effect, and thus improving user convenience. Can be

[5] Modification [5.1] Modification 1
In the above embodiment, the case has been described in which only the book purchase history is managed and the user recommends an unpurchased book. However, the user's read range is managed like the bookmark function of the electronic book terminal, and the book Unread / read information may be used for recommendation.

  In this case, a field for storing the user's read area is provided in the purchase history management DB 303. For example, the browsing application detects that the last page has been opened when browsing a book, and the user ID, the book ID, and the reading finish on the server. It is sufficient to notify that and store it in the field.

[5.2] Modification 2
Moreover, in the said embodiment, the preference information which shows a user preference is produced | generated from the purchase tendency of a book, or the tendency of a read book, cos similarity degree between preference information is calculated, and a similarity degree becomes more than a predetermined threshold value. Users may be extracted as similar users with similar preferences, and recommended books may be extracted from books already purchased by similar users.

  With this configuration, a book purchased by another user who has a preference similar to that of the user can be determined as a recommended book, and a recommended book can be determined in consideration of the user's preference.

[5.3] Modification 3
In addition, the bookstore nearest to the station on the route may be extracted for store recommendation for users in the train movement state.

  In this case, for example, the route and the up / down are estimated from the position change and route information of the latest user, the station on the destination is extracted, and purchased at the actual store (bookstore) S around the station. If a possible book is selected as a recommendation target, the advertising effect can be further improved.

[5.4] Modification 4
Moreover, in the said embodiment, the time slot | zone which distributes recommendation information is changed according to a state, for example, when it is a train movement state, it is highly likely that a user will leave a office, and recommendation information in a time slot | zone of 17: 00-20: 00 The management server side of the management server device 30 can set an appropriate delivery time zone, such as delivering a message and not entering a particular time for entering the store, or not sending all messages in the late night to early morning hours. You may do it.

  Moreover, you may consider the day of the week on which recommendation information is distributed. For example, a message may not be sent to a user who is in a standby state on a busy Monday to Friday morning, and recommendation information may be distributed during a Saturday and Sunday morning time when going out such as shopping is active.

  Further, the distribution time of the recommended information is determined based on the purchase time zone of the book by identifying the tendency of the time zone where the user is likely to purchase the book (for example, the purchase is always made after leaving the office). You may do it.

  In addition, for example, 24 hours is divided into 8 time zones in 3 hours, and the time zone in which books are often purchased for each user and the user behavior state at that time are tabulated. In such a case, a method of distributing recommendation information even in a restricted time zone may be employed.

[5.5] Modification 5
Moreover, in the said embodiment, a meaning may be given to the positional information on a route or a standby state for every user from the log of user positional information and user action information, and it may be utilized for delivery of recommendation information.

  For example, a route that is used more than an arbitrary number of times (5 days from Monday to Friday x 2 times in the morning / night x 4 weeks x 0.8 = 32 error factors) during an arbitrary period (for example, 1 month) , Meaning as commuting / commuting routes, and extracting the starting station and ending station from the route information with the same meaning, and extracting the nearest bookstore of the station as the nearest bookstore, or commuting / commuting You may make it determine a recommendation object book by methods, such as giving a weight to a recommendation book from the category tendency of a purchased book on a route and other than that.

[5.6] Modification 6
Moreover, in the said embodiment, you may make it define another state as action information. For example, when the temporary standby state continues twice and the movement distance is estimated to be a walking movement, the walking state may be set, and recommendation information for recommending the nearest store may be distributed.

[5.7] Modification 7
In the above embodiment, when road information is defined as information similar to route information, and the user's moving distance or speed on the road range can be estimated to be a car movement (for example, 40 km / h or more) It is possible to adopt a method that includes not only the nearest store but also a distant store as a recommendation target, and assuming that the workplace is close to the route, the temporary train moving state continues for any number of times. If the movement distance is within walking distance, it may be estimated as a standby state.

[5.8] Modification 8
In the above embodiment, the management server device 30 is provided with each DB 301 to 308 and managed. However, each DB 301 is provided separately from the management server device 30 and managed by different computers. It may be.
