There may be.

<Use case>
Hereinafter, the outline of the use case of the restaurant information providing system 1 according to the present embodiment will be described, and the processes executed by the restaurant information providing server 100 and the user terminal 200 will be described.

With reference to FIG. 6, a use case diagram of the restaurant information providing system 1 is shown. As shown in the figure, the user can perform operations such as "execute a search", "change the search condition", and "change the basic information" as the user of the restaurant information providing system 1. The restaurant information providing system 1 provides functions such as "execution of search", "change of search condition", and "change of basic information" for these user operations. The use case disclosed in FIG. 6 is only an example, and the restaurant information providing system 1 may be configured as a system capable of providing various functions other than these.

As a process on the restaurant information providing system 1 side for providing the "change of basic information" function, a process of presenting a user interface for the user terminal 200 to input information necessary for changing the basic information to the user, A process in which the restaurant information providing server 100 updates the customer database 31 based on the information acquired through the user interface is included. The "basic information" referred to here refers to the basic customer information stored and stored in the customer database 31 shown in FIGS. 3 and 4.

The user interface for allowing the user to input the information necessary for changing the basic information is, for example, when the restaurant information providing system 1 is constructed as an HTTP-based web application, one or more input fields, submit buttons, etc. are used. It may be implemented as a provided web page. In this case, the information input by the user in the input field is transmitted to the system side triggered by the pressing of the submit button. The restaurant information providing system 1 sanitizes and normalizes the information input by the user and stores it in the customer database 31. The web page is transmitted to the user terminal 200 by the restaurant information providing server 100 configured to function as a web server, and is drawn by a web browser installed on the user terminal 200 or the like. The rendered web page is the user interface in this example.

The user interface is application software such as proprietary software (for example, "GourNavi (registered trademark) gourmet app" that users can download and use from AppStore (registered trademark) provided by Apple Computer (registered trademark) in the United States. Etc.). In that case, the protocol between the system and the user interface is not limited to HTTP, and various protocols can be used. Also, the hardware and software configurations can be modified accordingly.

The user interface does not have to be an interface that depends only on the visual sense, and may be constructed by, for example, an application having a voice recognition function and generating input information to the system according to the user's voice. The route from which the basic information given to the system by the user is acquired does not have to be limited to the user interface described here. There may be routes retrieved from other databases not shown.

As the processing on the restaurant information providing system 1 side for providing the "execution of search" function, the processing of presenting the user interface for the user terminal 200 to input the information necessary for executing the search to the user, the same user. The restaurant information providing server 100 searches the store database 32 based on the information acquired via the interface, the location information automatically acquired by the user terminal 200, and the information stored in the customer database 32. Processing to be done is included.

The user interface for prompting the user to enter the information required to perform the search is the same as described for the user interface for prompting the user to enter the information required to change the basic information described above, and is based on HTTP. It may be built using web technology or it may be built on a proprietary application as a platform.

Further, there is no reason why all the information necessary for executing the search must be acquired by such a user interface, and it may be appropriately acquired (aggregated) from another database or an external device. For example, the position information of the user terminal 200 is not premised on being manually input by the user, and the position information provided by the GPS function of the terminal or the position information calculated from the access point of the terminal may be acquired.

As the process on the restaurant information providing system 1 side for providing the "change of search condition" function, the process of presenting the user interface for the user terminal 200 to input the information necessary for changing the search condition to the user, A process in which the restaurant information providing server 100 resets search conditions based on the information collected via the user interface, and a process executed by the restaurant information providing server 100 in providing the above-mentioned "execute search" function. Includes processing to perform again.

<Restaurant search function>
Hereinafter, the processing for providing the "execution of search" function will be mainly described. With reference to FIG. 7, an example of a display screen displayed by the user terminal 200 is shown as an example of the input user interface. The user interface as shown in the figure is provided by the cooperation between the "restaurant search application" software pre-installed in the user terminal 200 and the hardware included in the user terminal 200. Alternatively, it may be provided by a web application provided by the restaurant information providing server 100.

FIG. 7A is an example of a screen displayed when the “restaurant search application” is started. In the figure, the input button 211 is a button for the user to explicitly instruct the acquisition of the position information in the geographic coordinate system of the user terminal 200. The location information of the location of the user terminal 200 may be automatically acquired regardless of such a button. The specific method of acquiring the position information is not limited and may be provided by GPS (Global Positioning System) or may be provided by other techniques well known to those skilled in the art.

The input button 212 is a button for the user to explicitly instruct the restaurant information providing system 1 to use the restaurant search function which is the subject of the present embodiment. On the other hand, the input button 213 is a button for the user to explicitly instruct the restaurant information providing system 1 to use the normal restaurant search function. Since the normal restaurant search function is not the subject of this embodiment, the description thereof will be omitted.

When the input button 212 is pressed by the user, the user interface transitions to the screen shown in FIG. 7B. FIG. 7B is an example of a screen for determining the search condition in the restaurant search function provided by the “restaurant search application”. In the figure, the input field 214 is a button for inputting the time when the search is executed. Normally, the current time is automatically input using the system clock of the user terminal 200 or the like, but an arbitrary time may be input by the user.

The input field 215 is a field for the user to input time information such as the time and time (for example, within one hour) that the user must return to the place where the search is started in the restaurant information providing system 1. .. When the time information is not specified, it is automatically specified based on the "lunch time" information stored in the basic information of the customer of the user stored in the customer database 31.

The input field 216 is a field for the user to input the upper limit of the range for executing the restaurant search into the restaurant information providing system 1. The upper limit of the range in which the restaurant search is executed is expressed by a distance, for example, several hundred meters. In the following, the upper limit of the range in which the restaurant search is executed is referred to as "distance D1". Note that FIG. 7B shows an example of a user interface in which the distance D1 is specified by the walking time. The conversion from time to distance may be executed by the user terminal 200 or the restaurant information providing server 100.

The input button 217 uses the search conditions determined by the user interface shown in FIG. 7B to give a command for the user to execute a search for restaurant information according to the present embodiment. It is a button to input to.

With the input user interface as described above, the location information of the user terminal 200, the time when the user has to return to the starting point of the search, and the like are input to the restaurant information providing system 1. These information are input to the control unit configured around the CPU 11 of the restaurant information providing server 100. The input source of these information is not limited to the input user interface as described above, and various databases stored in the storage unit 18 may be used.

The restaurant information search according to the present embodiment, which is shown in FIG. 7A as “searching for a restaurant different from usual”, differs from the normal restaurant search in at least the following points. That is, a process is performed so that stores within a distance D2 (D2 <D1), which is a distance closer to the search start point than a predetermined distance D1 from the point centered on the search start point, are not presented to the user. Is different from the usual restaurant search.

In the conventional service for searching restaurant information, it is common to search for stores near the specified geographic coordinates, but in such a conventional service, the search is performed. Users tend to select nearby search results from the search starting point, and it was difficult to provide an opportunity to meet new stores. On the contrary, there is a problem that it is difficult for the store side to have a chance to meet new customers.

Further, in the conventional technology as described above, when a lunch search is performed during a lunch break or the like, 1. I want to avoid meeting colleagues in the company near me. I can't meet the needs of people who want to change their mood by walking or going out a little longer. Therefore, in the present embodiment, when either the distance D1 or D2 is set, the CPU 11 automatically sets the other. Then, the CPU 11 is configured to search for restaurants in the area surrounded by the concentric circles defined by the distance D1 and the concentric circles defined by the distance D2.

According to the restaurant search of the present embodiment, stores within a distance D2 (D2 <D1), which is a distance closer to the search start point than a predetermined distance D1 from the point centered on the search start point, are not presented. Rather, the search results are focused on restaurants in areas that you don't usually visit. Therefore, it is possible to give the user an opportunity to meet such a store.

<Operation of restaurant information providing server 1>
With reference to FIG. 8, an example of the flow of processing executed by the restaurant information providing server 100 is shown. The CPU 11 of the restaurant information providing server 100 has a relationship of D2 <D1 with respect to the store database 32 with the geographical coordinates specified by the position information of the user terminal 200 and the above-mentioned upper limit “distance D1” of the search range. A search is performed using "distance D2" as a parameter (S11).

In S11, D1 given as a parameter to the store database 32 is input by the input user interface described with reference to FIG. 7, or a default value is set. The CPU 11 of the restaurant information providing server 100 of the present embodiment automatically sets D2 when D1 is set by user input or by a default value. The timing of the automatic setting of D2 is not limited, and may be, for example, the timing of S11 in FIG. 8 or the time when the flow of FIG. 8 is started. As a result, the width of the area sandwiched between D1 and D2 is automatically determined, and the user can be encouraged to take a walk to a place slightly farther than usual.

As a result of S11, the CPU 11 is defined by the geographic coordinates (center) where the user terminal 200 is located and the circle defined by the distance D1, and the geographic coordinates (center) where the user terminal 200 is located and the distance D2. The restaurants in the area sandwiched by the circles are obtained as output from the store database 32.

With reference to FIG. 9, a conceptual diagram for explaining the information output by the CPU 11 by the process of S11 is shown. As shown in the figure, the process of S11 extracts restaurants in an area sandwiched between two concentric circles centered on the user terminal 200, a circle at a distance D1 and a distance D2.

Subsequently, the CPU 11 compares the number of stores extracted in S11 with a predetermined threshold value (S12). When the CPU 11 determines that the number of extracts of S11 is equal to or less than a predetermined threshold value as a result of the comparison determination of S12, the search condition is changed (S14), and the process is restarted from S11.

When the CPU 11 determines as a result of the comparison determination of S12 that the number of extracted restaurants exceeds a predetermined threshold value (S12, Yes), the restaurant information providing server 100 transmits the extracted restaurant information to the user terminal 200. (S13).

The extracted restaurant information may be output in the form of display output. In that case, the CPU 11 or the restaurant information providing server 100 may be used with respect to the user terminal 200 as shown in FIG. Send information that superimposes various drawings on the map. The user terminal 200 displays a drawing as shown in FIG. 9 based on the received information. The output of information is not limited, and may be performed in the form of listing store names, for example.

The restaurant information providing server 100 transmits the extracted restaurant information to the browser of the user terminal 200 or the "restaurant search application". Based on the received information, the user terminal 200 outputs a display that plots the restaurant icon on the map and presents it to the user. Alternatively, restaurant information may be listed with a brief introduction. When the user clicks or taps the restaurant icon on the map, a page introducing the outline of the store or the like may be displayed based on the basic information of the store shown in FIG.

<Operation of restaurant information providing server 2>
As a method for the restaurant information providing server 100 to search the restaurant database 32 in the area sandwiched between two concentric circles centered on the position of the user terminal 200, the CPU 11 of the restaurant information providing server 100 first uses the CPU 11 of the restaurant information providing server 100. The process may be carried out by searching for stores within the distance D1 and then removing the stores within the distance D2. Hereinafter, the flow of processing when the restaurant search of the present embodiment is performed by this method will be described with reference to FIG.

With reference to FIG. 10, another example of the flow of processing executed by the restaurant information providing server 100 is shown. The CPU 11 of the restaurant information providing server 100 searches the store database 32 with the geographic coordinates specified by the position information of the user terminal 200 and the upper limit "distance D1" of the above-mentioned search range as parameters (S21). .. The CPU 11 obtains restaurants within the range of the distance D1 as output from the store database 32, centering on the geographic coordinates where the user terminal 200 is located.

Subsequently, the CPU 11 searches for restaurants within the distance D2, as in S21 (S22). As a result, the CPU 11 obtains the restaurants within the range of the distance D2 as output from the store database 32, centering on the geographical coordinates where the user terminal 200 is located.

Subsequently, the CPU 11 is a restaurant that meets the condition that it is within the range of the distance D1 and not within the range of the distance D2 about the geographic coordinates where the user terminal 200, which is the center (starting point) of the search, is located. Extraction is performed (S23).

Subsequently, the CPU 11 compares the number of stores extracted in S13 with a predetermined threshold value (S24), changes the search condition if it is equal to or less than the predetermined threshold value (S26), and restarts from S21.

If the number of extracted restaurants exceeds a predetermined threshold value, the restaurant information providing server 100 transmits the extracted restaurant information to the user terminal 200 (S25). The output form of the extracted restaurant information may be in the form of display output. In that case, the CPU 11 or the restaurant information providing server 100 has a drawing as shown in FIG. 9 with respect to the user terminal 200. Is transmitted so that the information is superimposed on the map. The user terminal 200 displays a drawing as shown in FIG. 9 based on the received information. The output of information is not limited, and may be performed in the form of listing store names, for example.

The restaurant information providing server 100 transmits the extracted restaurant information to the browser of the user terminal 200 or the "restaurant search application". Based on the received information, the user terminal 200 outputs a display that plots the restaurant icon on the map and presents it to the user. Alternatively, restaurant information may be listed with a brief introduction. When the user clicks or taps the restaurant icon on the map, a page introducing the outline of the store or the like may be displayed based on the basic information of the store shown in FIG.

<Change of search conditions>
In the above description of the restaurant search function, only "distance D2 is shorter than distance D1" is defined, but the CPU 11 is configured to automatically determine the value of distance D2 according to the value of distance D1. You may. According to such a configuration, the area for recommending restaurants can be changed in response to the change of the search condition of changing the distance D1, and the store suitable for the condition can be searched.

There is no limitation on the specific method for automatically determining D2, and for example, D1-D2 may be set to a constant value (for example, 100 meters). In the present embodiment, in particular, when the distance D1 is increased, that is, when the distance D1 is changed in the direction away from the center point of the search (geographic coordinates where the user terminal 200 is located), D1-D2 decreases. As described above, the CPU 11 sets the distance D2.

With reference to FIG. 11, an example of a correlation in which D1-D2 decreases when D1 increases is shown. As shown in the correlation A of FIG. 11, the CPU 11 may automatically set the distance D2 so that D1-D2 decreases linearly with the increase of D1. Further, it may be automatically set so as to show the decrease as shown in the correlation B.

The change of the distance D1 and the change of the distance D2 accompanying the change are executed by the CPU 11 by inputting a control command instructing the CPU 11 to change the distance D1. Such a control command is generated when the user changes the distance D1 using the input field 216 in the input user interface as shown in FIG. Alternatively, it is generated when the search condition in S16 of FIG. 10 is changed. The CPU 11 may generate the control command.

The restaurant information providing server 100 of the present embodiment narrows the search target area when the range for searching restaurants is changed by the user or the system, especially when the range is changed in the direction of expanding the range. I do. Expanding the maximum value of the search range has the implication that there is some shortage in the search results before expansion. Therefore, by narrowing the search target area and controlling so that the search results judged to be insufficient are not positively displayed, it is possible to make the search results farther away stand out, which is a new store for the user. Opportunities to meet with will increase.

In the above-mentioned search condition change process, the distance D1 is changed first, and the CPU 11 sets the distance D2 according to the changed D1. However, unlike this flow, the distance D2 is changed first. Therefore, the CPU 11 may set D1 according to the changed D2.

The CPU 11 may automatically determine the distance D1 as follows. The automatic setting of the distance D1 will be described with reference to FIG. FIG. 12 shows a time T2 for providing food and drink at a certain store and a round-trip time T3 for heading to the same store. In FIG. 12, if the means of transportation is limited to one type, such as walking, the CPU 11 can automatically determine the distance D1 if the round-trip time T3 is determined.

Assuming a lunch search in the office, users usually have a fixed amount of time for lunch. Let T1 be the time until the user returns to the search point. In the present embodiment, T1 is grasped by the restaurant information providing system 1 as information called "lunch time" in the basic customer information stored in the customer database 31. When T1 is not input or the like, lunch is taken at a certain fixed time. Therefore, the CPU 11 sets the customer database 31 as, for example, "1 hour".

Here, the time T2 required to provide food and drink changes depending on the genre of the store and the degree of congestion. The genre of a store is different from, for example, fast food and restaurants, and if it is fast food, food and drink are provided quickly. Restaurants serve food and drink later than fast food. T2 may be set according to the genre of the store. Note that T2 also includes the time it takes for the user to have lunch.

T2 may be changed by the CPU 11 according to the degree of congestion. In this case, T2 is set according to, for example, the time when the CPU 11 executes the restaurant search of FIG. 8 (for example, it may be the time when S11 or S12 is executed). Many stores are crowded at lunch time, and many are vacant outside lunch time. Therefore, when the time for executing the restaurant search corresponds to the lunch time, the CPU 11 sets T2 longer, and when the time for executing the restaurant search deviates from the lunch time, the CPU 11 sets T2 shorter.

The CPU 11 uses T1 and T2 determined as described above to calculate the time T3 at which the user can spend money on movement. For example, T3 is obtained from the equation T1-T2 = T3. The CPU 11 calculates the distance D1 based on the calculated round-trip time T3 and the means of transportation (walking, etc.). Since T1 and T2 are automatically determined as described above, the distance D1 is also automatically calculated by the CPU 11.

In this case, the distance D1 is set at the starting point of the search within the range in which the user can return within the time of T1. The distance D1 is automatically calculated by the restaurant information providing system 1 of the present embodiment, and the distance D2 is also automatically set by the above-mentioned process, so that the user can go out and enjoy lunch in a realistic range. It will be possible to propose an outing within.

The distance D1 automatically calculated by the restaurant information providing system 1 of the present embodiment may be fed back to the restaurant search as shown in FIG.

<Modification example>
The above embodiment can also be implemented as follows, for example.

The search condition input user interface shown in FIG. 7 does not have a function for specifying restaurant attributes (genres), but has a field for specifying restaurant attributes as one of the input fields. , When the restaurant search (S11, S12) described with reference to FIG. 10 is performed, the restaurant attribute is also one of the search conditions. Since the attributes of restaurants are set for each store as shown in FIG. 5, if one of the search conditions is set in this way, the search results can be filtered by the attributes (genre).

Further, in the above-described embodiment, a configuration is disclosed in which the means of transportation is determined in advance when the distance D1 is automatically calculated. On the other hand, the restaurant information providing system 1 or the restaurant information providing server 100 presents an input user interface for switching the means of transportation, and the user switches the means of transportation (for example, changing from walking to moving by a passenger car). Then, the distance D1 may be automatically changed accordingly. In this case, the upper limit of the search range changes dynamically, and the stores to be searched also change accordingly.

Further, in the above embodiment, an example in which a user whose user information is registered in the customer database 31 searches for a restaurant has been mainly described. In the case of the above embodiment, the restaurant information providing server 100 or the like can perform information processing such as a search by using the user information registered in the customer database 31. In that respect, the above embodiment is advantageous, but it is not essential that the user information is registered in the customer database 31.

For example, the technical idea disclosed in the above embodiment is for a case where a user who is not registered in the customer database 31 searches by inputting search conditions from the surface in a search composed of web pages. Can also be applied. In this case, the user interface screen as shown in FIG. 7 is composed of a web page and displayed on the user terminal 200. In addition, the lunch time time (predetermined first time) and location information are input by the user or the user terminal 200 into the restaurant information providing system 1. As a specific method of inputting the lunch time, for example, a method of manually inputting by the user or a method of setting a default lunch time between 12:00 and 13:00 can be used. Specific methods for inputting location information include, for example, a method in which the user manually inputs, and a method in which the user terminal 200 acquires latitude and longitude information from the outside by its own GPS function and automatically inputs the information. it can.
