In the following, a map search service will be explained as an example.

[Functional configuration]
FIG. 1 is a diagram showing the overall configuration of an information processing system S according to an embodiment. The information processing system S includes, for example, an information processing device 100 and one or more terminal devices 10. Information processing device 100 is connected to terminal device 10 via network NW. The network NW includes, for example, some or all of the Internet, a WAN (Wide Area Network), a LAN (Local Area Network), a provider device, a wireless base station, a dedicated line, and the like. The information processing device 100 is an example of an “information processing device”.

The terminal device 10 is operated by a user who uses information provided by the information processing device 100. The terminal device 10 is, for example, a computer device such as a mobile phone such as a smartphone, a tablet terminal, a personal computer, or a PDA (Personal Digital Assistant). The information provided by the information processing device 100 includes, for example, an application page referenced by an application program started on the terminal device 10 and a web page referenced by a browser started on the terminal device 10.

When the terminal device 10 receives a predetermined operation from the user, it communicates with the information processing device 100 via a pre-installed application or browser, acquires data to be displayed or played on the application or browser, and displays an application page or Display a web page. This app page or web page contains map information.

The information processing device 100 is an application server device that communicates with a terminal device 10 on which an application has been started and exchanges various information on the Internet. Alternatively, the information processing device 100 is a web server device that communicates with a terminal device 10 on which a browser is activated on the Internet to provide a web page.

The information processing device 100 includes, for example, a communication section 110, a control section 120, and a storage section 130. The communication unit 110 includes, for example, a communication interface such as a NIC. The communication unit 110 communicates with the terminal device 10 via the network NW.

The control unit 120 controls the operation of the information processing device 100. The control unit 120 includes, for example, an acquisition unit 121, a determination unit 123, a search result generation unit 125, a provision unit 127, and an update unit 129.

The acquisition unit 121 acquires, from the terminal device 10 via the communication unit 110, a query input by the user to an application page or a web page, and regional information (location information) that is a search target based on the query. do. A query is a character string for specifying a target for which a user requests information on an application page or a web page that provides a search service. The query is, for example, a character string such as "cafe" or "ramen." The regional information (location information) is, for example, the location of the terminal device 10 (i.e., the user's location) obtained by positioning based on radio waves received from a satellite using a GPS (Global Positioning System) function provided in the terminal device 10. shows. Alternatively, the regional information (location information) indicates, for example, the location of the terminal device 10 (that is, the user's location) estimated from the location of a wireless base station with which the terminal device 10 can communicate. Regional information (location information) is represented by, for example, a combination of latitude information and longitude information. Alternatively, the regional information (location information) may indicate, for example, a location or region that is a search target specified by the user in an application page or a web page. The acquisition unit 121 is an example of an “acquisition unit”.

The determining unit 123 determines search result candidates corresponding to the acquired query based on the regional information acquired by the acquiring unit 121 and the characteristics of the corresponding area. Details of the processing by the determining unit 123 will be described later. The determining unit 123 is an example of a “determining unit”.

The search result generation unit 125 generates search result information (search result page) corresponding to the search result candidate finally selected by the user from among the search result candidates determined by the determination unit 123 and presented to the user. do. Details of the processing by the search result generation unit 125 will be described later.

The providing unit 127 provides the search result candidates determined by the determining unit 123 and the search result information generated by the search result generating unit 125 to the terminal device 10 via the communication unit 110. The providing unit 127 is an example of a “providing unit”.

The updating unit 129 updates query information D4 (ranking information), which will be described later, based on statistical information (access history) of accesses to each link included in the search result information (search result page). The updating unit 129 is an example of an “updating unit”.

Each component of the control unit 120 is controlled by a processor (or processor circuit) such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) by executing a program (software) stored in the storage unit 130. Realized. In addition, some or all of the components of the control unit 120 may be hardware (circuit units) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), etc. ), or by collaboration between software and hardware. Further, the program referenced by the processor may be stored in advance in the storage unit 130 or in a removable storage medium such as a DVD or CD-ROM, and the storage medium may be stored in the drive of the information processing device 100. It may be installed in the storage unit 130 from a storage medium by being attached to the device.

The storage unit 130 is realized by, for example, a ROM (Read Only Memory), a flash memory, an SD card, a RAM (Random Access Memory), an HDD (Hard Disc Drive), a register, or the like. Furthermore, the storage unit 130 may be partially or entirely a NAS (Network Attached Storage), an external storage server device, or the like. The storage unit 130 stores, for example, map information D1, area information D2, facility information D3, query information D4, user information D5, access log D6, and the like. The map information D1 is information for determining the position on the electronic map, and includes information on the positions of roads, topography, various facilities, and various stores.

The regional information D2 defines regional characteristics for each region. The characteristics of a region are the overall characteristics (characteristics) of that region. Regional characteristics may refer to the characteristics of the area itself, such as whether it is a business district or a residential area, whether it is in the city center or a suburb, or whether it is a high-end product (high price range). It may also indicate the nature (taste, personality) of the people staying in the area, such as whether the area is a place where people who like things gather or people who like high-quality things gather. FIG. 2 is a diagram showing an example of regional information D2 according to the embodiment. In the example shown in Figure 2, for example, for "region ID: 10001" and "region name: Minato-ku, Tokyo", the characteristics of the region are "use: business district", "price range: high", "quality :High" is associated and defined. Note that the region classification is not limited to "ward", but may be set in detail such as "town", "village", "station", etc., or may be set broadly such as "prefecture".

The facility information D3 defines facility information for each facility. FIG. 3 is a diagram showing an example of facility information D3 according to the embodiment. In the example shown in FIG. 3, for example, for "facility ID: 00001" and "facility name: 1st Cafe", the facility information includes "price range: high", "location: near station/in arcade", " "Alcohol provided: Yes", "Scale: large", and "Reviews: high" are associated and defined. The facility information D3 defines, for example, information about chain stores and franchise stores (fast food restaurants, family restaurants, convenience stores, etc.) that have multiple facilities (stores) with the same store name all over the country.

The query information D4 defines, for each query, a ranking (standard ranking) that is a standard for presenting search result candidates. The standard ranking is set, for example, based on statistical information calculated using the access log D6 to each link included in the search result page. The standard ranking is set, for example, in the access log D6 to each link included in the search result page, in order of the facilities accessed most frequently. FIG. 4 is a diagram showing an example of query information D4 according to the embodiment. In the example shown in FIG. 4, for example, for "query: cafe", the standard ranking is prioritized in the order of "1st cafe", "6th cafe", "2nd cafe", and "3rd cafe". The associated facilities are defined in association with each other.

The user information D5 defines user attributes and past search history for each user. FIG. 5 is a diagram showing an example of user information D5 according to the embodiment. In the example shown in FIG. 5, for example, "user ID: 001" is associated with "age: 30s," "gender: male," and "search history: Daiichi Cafe, Ramen A." It is defined as User information D5 may include other conversion (CV) information in addition to search history. In addition, the user information D5 may include information on facilities bookmarked by the user and information on facilities set as destinations in past route guidance.

[Processing flow]
The processing of the information processing system S will be described below. FIG. 6 is a sequence diagram illustrating an example of processing of the information processing system S according to the embodiment. The sequence diagram shown in FIG. 6 is started, for example, when a user operates the terminal device 10 and inputs a query into the search window of an app page or web page that includes map information in which a region is specified. Ru. In the following, an example will be described in which a user operates the terminal device 10 and inputs a query into a search window of an application page.

First, the terminal device 10 transmits to the information processing device 100 a query input by the user to the application page and regional information to be searched by the query (step S101). For example, the terminal device 10 transmits the character string “cafe” as a query and the current location of the terminal device 10 (that is, the current location of the user) as regional information to the information processing device 100.

Next, the determining unit 123 of the information processing device 100 refers to the query information D4 and obtains the reference ranking corresponding to the query transmitted from the terminal device 10 (step S103). Next, the determining unit 123 narrows down facilities by referring to the map information D1 and excluding facilities that do not exist within a predetermined range based on the acquired regional information from the facilities included in the standard ranking. (Step S105).

Next, the determining unit 123 refers to the regional information D2 and the facility information D3, adjusts the ranks of the facilities included in the narrowed-down ranking, and determines search result candidates (step S107). For example, when the area corresponding to the acquired area information is "Minato-ku, Tokyo," the determining unit 123 refers to the area information D2 shown in FIG. 2 and determines the characteristics of the area corresponding to "Minato-ku, Tokyo." get. In the example shown in Figure 2, the information that the characteristics of the area corresponding to "Minato-ku, Tokyo" are "use: business district", "price range: high", and "quality: high" is acquired. . Furthermore, the determining unit 123 refers to the facility information D3 shown in FIG. 3 and extracts facilities that correspond to (fit) the characteristics of the area corresponding to "Minato-ku, Tokyo." For example, the determining unit 123 selects "First Cafe" whose "price range is high" in the facility information D3 as a facility corresponding to the characteristics of the area ("price range: high") corresponding to "Minato-ku, Tokyo". and "3rd Cafe" are extracted. Further, for example, the determining unit 123 may select "Location: Near station" and "Size: Large" in the facility information D3 as a facility corresponding to the characteristics of the area ("Use: Business district") corresponding to "Minato-ku, Tokyo". "The first cafe" and the "second cafe" are extracted. The determining unit 123 then adjusts the ranking of the facilities included in the ranking so that the extracted facility has a higher ranking, and determines search result candidates. Alternatively, the determining unit 123 selects "Second Cafe" with "Price Range: Low" in the facility information D3 as a facility that does not correspond to the characteristics of the area ("Price Range: High") corresponding to "Minato-ku, Tokyo". and "4th Cafe" are extracted. Then, the determining unit 123 may adjust the ranking of the facilities included in the ranking so that the extracted facility has a lower ranking, and determine search result candidates.

As described above, each item of regional characteristics defined in the regional information D2 and each item of facility information defined in the facility information D3 are associated in advance. The determining unit 123 may adjust the ranking of the facilities based on a calculation formula defined in advance based on such a correspondence relationship. In this calculation formula, an individual score indicating the suitability of each facility included in the ranking is calculated based on the facility information D3 for each of the regional characteristics defined in the regional information D2, and the total value of the individual scores is calculated. The ranking of facilities may be determined in descending order of . Note that the same item may be defined in the area characteristics defined in the area information D2 and the facility information defined in the facility information D3.

That is, the determining unit 123 determines a plurality of prioritized search result candidates. The determining unit 123 determines search result candidates such that search result candidates that match the characteristics of the region have a higher priority. The determining unit 123 determines facility candidates that exist within a predetermined range defined based on regional information and that correspond to the acquired query. The determining unit 123 determines search result candidates by adjusting ranking information of search result candidates defined in advance for each query based on regional characteristics.

Note that the determining unit 123 may adjust the order of the facilities included in the ranking based on time information and date information (day pattern). For example, the ranking of facilities included in the ranking may be adjusted so that facilities that serve alcohol will be ranked higher during nighttime hours, Christmas, New Year's holidays, etc.

Further, the determining unit 123 may adjust the order of the facilities included in the ranking based on the user's means of transportation. For example, when the user's means of transportation is a "car" (when using a car navigation system), the ranking of facilities included in the ranking may be adjusted so that facilities that do not serve alcohol are ranked higher.

Further, the determining unit 123 may adjust the ranking of facilities included in the ranking based on weather information. For example, when the weather is "rainy," the ranking of facilities included in the ranking may be adjusted so that facilities near a station or facilities in an arcade are ranked higher.

Note that if the information on the area corresponding to the acquired area information is not registered in the area information D2, the determining unit 123 selects the area corresponding to the acquired area information among the areas registered in the area information D2. The ranking of facilities may be adjusted based on relevant regional information. For example, if the information on the area corresponding to "Asakusa" is not registered in the area information D2, the determining unit 123 selects the area information registered in the area information D2 for "Kitasenju", which is a downtown area like "Asakusa". may be used to adjust the ranking of facilities.

Next, the determining unit 123 refers to the user information D5 and readjusts the ranking of the search result candidates (step S109). For example, if the information acquired by the acquisition unit 121 includes login information for the user's map search service (user ID, etc.), the determination unit 123 determines that user information exists. When determining that user information exists, the determining unit 123 refers to the user information D5 and readjusts the ranking of search result candidates. In the example shown in FIG. 5, user information of age "30s" and gender "male" is associated with user ID "001". The determining unit 123 readjusts the ranking of the facilities included in the ranking so that the ranking of the facility having facility characteristics suitable for the information associated with this user ID in the user information D5 becomes higher.

Furthermore, in the example shown in FIG. 5, the user ID "001" is associated with the history of accessing the "First Cafe" page as the past search history. In this case, the determining unit 123 readjusts the ranking of the facilities included in the ranking so that the ranking of the facility corresponding to this past search history becomes higher. Note that if there is an access history to a facility that is not included in the ranking as a past search history, information on this facility may be incorporated into the standard ranking.

That is, the determining unit 123 adjusts the determined search result candidates based on the user's attribute information. Further, the determining unit 123 adjusts the determined search result candidates based on the user's past search history.

Next, the providing unit 127 transmits the prioritized search result candidates to the terminal device 10 via the communication unit 110 (step S111). As a result, prioritized search result candidates are displayed on the display unit of the terminal device 10 (step S113). FIG. 7 is a diagram illustrating an example of a search result candidate display screen P1 according to the embodiment. In the example shown in FIG. 7, when "cafe" is input in the search window SW, the search result candidate field SC includes "1st cafe", "3rd cafe", "2nd cafe", "4th cafe", and "4th cafe". Buttons are displayed in the order of "Cafe", "6th Cafe", and "5th Cafe". That is, in this example, as a result of considering the characteristics of the region and the user's attributes or search history, "Daiichi Cafe" is selected as the search result candidate with the highest priority, and is placed in the upper left of the candidate column SC (position where it is most likely to be selected). is displayed. If any of these buttons is pressed, the terminal device 10 acquires search result designation information (step S115), and transmits the search result designation information to the information processing device 100 (step S117).

Next, the search result generation unit 125 generates search result information according to the designation of the search result transmitted from the terminal device 10 (step S119), and transmits it to the terminal device 10 via the communication unit 110 ( Step S121). As a result, search result information is displayed on the display unit of the terminal device 10 (step S123).

FIG. 8 is a diagram showing an example of the search result information display screen P2 according to the embodiment. In the example shown in FIG. 8, as a result of pressing the "first cafe" button on the display screen P1 shown in FIG. 7, search result information regarding the first cafe is displayed. With the above steps, the processing of this flowchart is completed.

According to the embodiment described above, an acquisition unit (acquisition unit 121) that acquires a query input by a user and regional information to be searched by the query; A determining unit (determining unit 123) that determines search result candidates corresponding to the acquired query based on the characteristics and information indicating the determined search result candidates are sent to the user's terminal device (terminal device 10). By providing a providing unit (providing unit 127), it is possible to provide search results that take regional characteristics into consideration.

Note that some or all of the functions of the information processing device 100 described above may be realized as functions of an application program started on the terminal device 10. In this case, an application program started on the terminal device 10 or a combination of an application program started on the terminal device 10 and a program started on the information processing device 100 is an example of a “program”.

Although the mode for implementing the present invention has been described above using embodiments, the present invention is not limited to these embodiments in any way, and various modifications and substitutions can be made without departing from the gist of the present invention. can be added.
