Description

The present invention relates to matching systems, matching methods, and programs.

Various matching systems that connect service providers and service users through media such as matching sites have been conventionally developed. Among them, the following Patent Document 1 discloses a matching system that can be used for a food and drink entertainment service in which a service provider acts together with a customer (service user) at a predetermined waiting place.

Japanese Patent No. 6675757

The matching system disclosed in Patent Document 1 relates to a system including a service provider terminal possessed by the service provider and a server device capable of communicating with the service provider terminal. In the matching system disclosed in Patent Document 1, the service provider terminal measures the customer service time by the operation of the service provider, and transmits the measured customer service time to the server device. Further, the server device calculates the cost related to the service provision (the cost incurred in the customer service) according to the customer service time received from the service provider terminal.

By the way, the information provided to the service user from the matching system is limited to only a part of the information of the service provider. Therefore, the service user selects the service provider from the fragmentary information provided by the matching system. Therefore, if objective evaluation information about the service provider is obtained, the service user can grasp that he / she is a service provider more suitable according to his / her request before making a reservation. Further, for the service provider, if the objective evaluation information of the service user is obtained, it is possible to accurately determine whether or not to accept the reservation application from the service user based on the evaluation information. However, for example, the means for providing the evaluation information of the service provider or the service user that can be referred to at the time of reservation application is neither disclosed nor suggested in Patent Document 1.

In view of the above problems, the present invention provides evaluation information of a service provider or a service user, and provides a matching system, a matching method, and a program capable of accurately determining whether or not the other party meets the needs of both parties. With the goal.

The matching system according to the present invention is
A matching system in which a first terminal operated by a service provider, a second terminal operated by a service user, and a management server are connected via a communication line.
The management server generates evaluation information of the service provider or the service user based on at least one of the total charge, the total time, and the number of times of the service performed between the same service provider and the service user.

According to this aspect of the invention, a service provider or service is based on at least one of a total charge, total time, and number of services performed by the management server between the same service provider and service user. The evaluation index of the user is judged, and the obtained evaluation information is provided to both the first terminal (the service provider who receives the reservation application) and the second terminal (the service user who intends to make the reservation application to the service provider). can do. As a result, according to this aspect of the present invention, the service provider and the service user refer to the evaluation information received before the reservation application and accurately determine whether or not the other party is suitable for their own request. be able to.

Further, in the matching system according to the present invention,
The evaluation information includes at least one of the index 1 to the index 3 determined by the following formula.
Is preferable.
Calculation formula of index 1: [the total charge of the service / the number of times of the service].
Calculation formula of index 2: [the total time of the service / the number of times of the service].
Calculation formula of index 3: [value calculated by index 1 / value calculated by index 2].

According to this aspect of the present invention, the management server can generate more objective evaluation information. Therefore, the service provider and the service user can more accurately determine whether or not the other party is more suitable for their own request by referring to the received evaluation information.

Further, the matching method according to the present invention is
A matching method executed in a matching system in which a first terminal operated by a service provider, a second terminal operated by a service user, and a management server are connected via a communication line.

Make it function as a means.

According to these aspects of the invention, the management server is based on at least one of the total charge, total time, and number of services of services performed between the same service provider and service user. The evaluation index of the service user is judged, and the obtained evaluation information is transmitted to both the first terminal (the service provider who receives the reservation application) and the second terminal (the service user who tries to make a reservation application to the service provider). Can be provided. As a result, according to these aspects of the present invention, before the reservation application, the service provider and the service user refer to the received evaluation information to determine whether or not the other party is more suitable for their own request. You can make an accurate judgment.

According to the present invention, it is possible to provide evaluation information of a service provider or a service user, and provide a matching system, a matching method, and a program capable of accurately determining whether or not the other party is more suitable according to the requests of both parties.

Hereinafter, desirable embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different embodiments and is not construed as being limited to the description of the embodiments shown below.

<Structure>
First, the configuration of the matching system 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram showing an outline of the configuration of the matching system 1 according to the present embodiment. Further, FIG. 2 is a functional block diagram of the management server 30 provided in the matching system 1.

As shown in FIG. 1, the matching system 1 includes a first terminal 10 operated by a service provider, a second terminal 20 operated by a service user, and a management server 30. Further, the first terminal 10, the second terminal 20, and the management server 30 are connected via the communication line 40. The matching system 1 in the present embodiment is used by a service provider and a service user who have received membership registration. However, it is not limited to this.

Further, in the matching system 1, the process of connecting the service provider and the service user may be substantially the same as that of the general matching system (the parts different from the general matching system will be described later). That is, the service user operates the second terminal 20 to access the management server 30, and obtains the list information of the service providers matching the desired conditions from the management server 30. The acquired list information is displayed on the second terminal 20. The service user browses the list information displayed on the second terminal 20 and selects the service provider judged to be most suitable for the request.

Subsequently, the management server 30 transmits a notification to the first terminal 10 of the selected service provider that the service user has requested to use the service in a predetermined time zone. At this time, when the service provider agrees to the notified service use request, matching between the service provider and the service user is established (the management server 30 is the service between the service provider and the service user). Execute the reservation process).

Next, it is preferable that the first terminal 10 and the second terminal 20 in the present embodiment are mobile terminals such as smartphones and tablet terminals. The first terminal 10 and the second terminal 20 in the present embodiment communicate with the management server 30 via a dedicated application, a web browser, or the like. Further, the management server 30 may be a general-purpose computer, and may be a calculation unit (for example, a processor such as a CPU), a storage unit (for example, a main memory such as a ROM or RAM, a storage such as an HDD or SSD), and a communication interface unit. And so on.

The calculation unit of the management server 30 performs a predetermined calculation based on the programs and data stored in the storage unit from various information received from the first terminal 10 and the second terminal 20 via the communication interface unit. Further, the calculation unit outputs various information generated from the calculation result to the first terminal 10, the second terminal 20, and the like.

The management server 30 according to the present embodiment functions as, for example, the means shown in FIG. 2 by processing in the arithmetic unit using the program or data. More specifically, the management server 30 functions as a communication means 31, a service start registration means 32, a service charge update means 33, a service end registration means 34, an evaluation means 35, a reservation frame transaction registration means 36, and the like.

The communication means 31 is a means for communicating with a terminal (for example, a first terminal 10, a second terminal 20, etc.) connected to the management server 30 via a communication line 40. The communication means 31 has a function of receiving various information (various notifications) from the first terminal 10 and the second terminal 20 and the like, or transmitting various information (various notifications) to the first terminal 10 and the second terminal 20 and the like. ..

Further, for example, the communication means 31 displays various page information displayed on the first terminal 10 and the second terminal 20 (for example, displayed on the first terminal 10 and the second terminal 20 when the application is executed) when the matching system 1 is used. The screen information of the matching site, the list information of the service providers, the schedule information of the service providers and the service users, etc.) are also included in the function of transmitting in response to the browsing request from the first terminal 10 and the second terminal 20. good.

Next, the service start registration means 32 (service start processing) is reserved in the storage unit of the management server 30 between the service provider who operates the first terminal 10 and the service user who operates the second terminal 20. It is a means to remember (register) that the service has started. The service start registration is based on a service start notification (relative notification) transmitted from at least one of the first terminal 10 and the second terminal 20 in which the service provider and the service user face each other at the waiting place.

Next, the service charge renewal means 33 (service charge renewal process) is after a predetermined time has elapsed from the start of the service (although it is not particularly limited, for example, the first 10 minutes have elapsed when a 60-minute service is reserved. When the service charge of (later) is updated, it is a means of storing (registering) the new service charge in the storage unit of the management server 30 (the process from the start of the service to the update of the service charge will be described later. ).

Next, when the service performed between the service provider and the service user is terminated, the service termination registration means 34 (service termination processing) stores the termination of the service in the storage unit of the management server 30 (the service termination processing). It is a means to register). In the service end registration, for example, after a predetermined time has elapsed from the start of the service, the management server 30 receives a service stop notification from at least one of the first terminal 10 and the second terminal 20, or the reserved service period ends. Based on things.

Next, the evaluation means 35 is a means for generating evaluation information of at least one of the service provider and the service user, and providing the obtained evaluation information, for example, at a stage before the reservation application. The evaluation means 35 in the present embodiment evaluates a service provider and a service user by, for example, the following index. However, the evaluation index is not limited to this.
(Index 1) Total service charge / Number of services provided (used) so far (Index 2) Total time of services / Number of services provided (used) so far (Index 3) Value calculated by Index 1 / Index 2 Value calculated in

The total charge of the service of (index 1) corresponds to the total charge of the service carried out between the same service provider and the service user. Further, the total time of the service of (index 2) corresponds to the total of the service time performed between the same service provider and the service user. Further, the "number of services provided (used) so far" in (index 1) and (index 2) corresponds to the number of services provided between the same service provider and service user. Further, when the service provider provides services to a plurality of service users, the management server 30 calculates each value of (index 1) to (index 3) for each service user, and then each service. The values related to the users may be added together to obtain the average value (the average value of each of (index 1) to (index 3) is calculated). The same applies to the case where the service user uses the service from multiple service providers.

According to (Index 1), the service provider can grasp the level of the charge obtained from one service user for each service. This makes it possible to evaluate the quality of service of each service provider. In addition, the service user can grasp the level of the charge paid to one service provider for each service. This makes it possible to evaluate whether or not the service user tends to pay a high fee.

Further, according to (Indicator 2), it is possible to grasp the length of time spent on the same partner. This makes it possible to evaluate whether or not the service provider or service user tends to establish a good relationship with the other party of the service. Further, according to (Indicator 3), the service provider can evaluate the charge obtained per hour, and the service user can evaluate the charge paid per hour.

Information such as the total charge per service for each service provider and service user, the number of services, and the time per service is stored in the storage unit of the management server 30. It is preferable that these pieces of information are systematically managed by a database constructed in the storage unit of the management server 30. The evaluation means 35 refers to the usage information stored in the storage unit, and obtains the numerical values of (index 3) from the (index 1).

Next, the reservation frame transaction registration means 36 stores the time frame (reservation frame) of the service already reserved between the service user and another service user in the storage unit of the management server 30. , It is a means to store (register) the identification information of the service user after the transaction and the service fee after the transaction. However, in the end, it is preferable that the transaction of the reservation slot requires the approval of not only the original service user but also the service provider who is the other party of the reservation. In the present embodiment, another service user may sell the purchased reservation frame to another service user.

<Service reservation processing>
Next, the service reservation process in the matching system 1 of the present embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram showing an example of a service provider's schedule screen displayed on the second terminal 20. Further, FIG. 4 is a diagram showing an example of a service provider's schedule screen displayed on the first terminal 10.

In response to the request from the second terminal 20, the management server 30 transmits the schedule information of the service provider selected by the service user. The second terminal 20 that has received the schedule information displays the schedule screen of the service provider as shown in FIG. Here, the cell corresponding to the line A in FIG. 3 indicates a time zone that can be reserved. Further, the cell corresponding to the line B in FIG. 3 indicates a reservation frame that can be traded. However, the mode of displaying the reservation available time zone and the transactionable reservation frame is not limited to this.

A service user who browses schedule information touches line A displayed on the screen of the second terminal 20, for example, and applies for a service reservation in the time zone. Accordingly, the second terminal 20 transmits the information of the time zone corresponding to the service provider and the line A to the management server 30.

Subsequently, the management server 30 transmits to the first terminal 10 that the service user has applied for the service use in the time zone corresponding to the line A, and requests a reply as to whether or not to accept the application. The service provider who has determined to receive the application sends a notification of acceptance of the application to the management server 30 via the first terminal 10. The management server 30 that has received the application acceptance notification stores the service provider, the service user, the reservation time zone, and the like as the service reservation information in the storage unit. Subsequently, the management server 30 transmits to the second terminal 20 that the service provider has received the reservation application.

As shown in FIG. 4, on the schedule screen that can be viewed on the first terminal 10 of the service provider, in addition to the line A indicating the reserved time zone and the line B indicating the transactionable reservation frame, the schedule screen is displayed. Then, the line C indicating the time zone in which the reservation cannot be made is displayed because the reservation with another service user is already filled. However, the mode of displaying the time zone in which reservation is not possible is not limited to this.

<Process until the service charge is updated>
Next, with reference to FIG. 5, a process when the service charge is updated within the service time will be described. FIG. 5 is a sequence diagram showing a process from immediately before the start of the reserved service to the update of the service charge within the service time.

As shown in FIG. 5, when the service user arrives at a predetermined waiting place (for example, a restaurant designated by the service user), the service user arrives at the waiting place from the second terminal 20 via the operation of the service user. A notification to that effect (notification of arrival at the waiting place) is transmitted to the management server 30 (S51). Upon receiving the waiting place arrival notification, the management server 30 transmits a notification (waiting place waiting notification) to the effect that the service user is waiting at the waiting place to the first terminal 10 (S52).

The service provider knows that the service user is waiting at the waiting place by receiving the waiting place waiting notification at the first terminal 10. After that, the service provider heads to the waiting place (restaurant) and faces the service user. At this point (for example, when the service user is seated at the table), the first terminal 10 transmits a relative notification with the service user to the management server 30 via the operation of the service provider (S53). In the matching system 1 according to the present embodiment, the relative notification with the service user is processed as the service start notification. At the same time, the management server 30 stores in the storage unit that the service has started (S54). This process corresponds to the service start registration means 32.

After a predetermined time has elapsed from the start of the service (for example, about 10 minutes after the transmission of the relative notification from the first terminal 10), the service provider once leaves the eating and drinking table with the service user. At this time, it is preferable that the first terminal 10 transmits a notification that the service provider has left the seat to the management server 30 via the operation of the service provider. Subsequently, the first terminal 10 transmits a charge negotiation notification or a service stop notification to the management server 30 via the operation of the service provider (S55).

The charge negotiation notice includes the desired value or the desired range of the subsequent service charges. For example, if the service charge at the time of initial reservation (service charge from the start of service to the time when a predetermined time elapses) is 2000 yen per hour, the service provider will charge "3000 yen per hour" as the subsequent service charge. Suppose you want. At this time, the first terminal 10 notifies the management server 30 of the desired value of the subsequent service charge (for example, 3000 yen per hour) via the operation of the service provider.

On the other hand, when the service provider wants to notify the desired range of the service charge after that (for example, the range of "3000 yen to 5000 yen per hour"), the service provider operates. The first terminal 10 notifies the management server 30 of a desired range (for example, 3000 yen to 5000 yen per hour).

Here, if the charge negotiation notification received from the first terminal 10 includes the desired value of the service charge (in the case of the above example, the desired value of "3000 yen per hour"), the management server 30 requests the desired value. The value is transmitted to the second terminal 20 (S56). On the other hand, if the charge negotiation notification received from the first terminal includes the desired range of service charges (in the case of the previous example, the desired range of "3000 yen to 5000 yen per hour"), the management server 30 , A notification (notice of request for negotiation) to the effect that the service provider has requested to negotiate the charge is transmitted to the second terminal 20 (S56).

When the second terminal 20 receives the desired value of the service charge and the service user accepts the desired value as the subsequent service charge, the second terminal 20 transmits an acceptance notification to the management server 30 (S57). .. Upon receiving the acceptance notification, the management server 30 updates the subsequent service charge to the desired value (“3000 yen per hour”) from the first terminal 10 (S58). This process corresponds to the service charge updating means 33.

At the same time, the management server 30 transmits a new service condition notification (service charge) to the first terminal 10 (S59). On the other hand, if the service user does not accept the desired value as the subsequent service charge, the subsequent service is terminated (service termination registration means 34).

Further, when the second terminal 20 receives the negotiation request notification, the second terminal 20 is set in the range desired by the service user as the subsequent service charge (for example, "2000 per hour" through the operation of the service user. "From Yen to 4000 Yen") is transmitted to the management server 30. At this time, the management server 30 has a desired range received from the first terminal 10 (“3000 yen to 5000 yen per hour”) and a desired range received from the second terminal 20 (“2000 yen to 4000 yen per hour”). ), The lower limit of the desired range from the first terminal 10 (“3000 yen per hour”) is less than or equal to the upper limit of the desired range from the second terminal 20 (“4000 yen per hour”). In that case, it is determined that the negotiation has been concluded, and the subsequent service charge is updated to the upper limit of the desired range from the second terminal 20 (“4000 yen per hour”) (S58). This process corresponds to the service charge updating means 33.

At the same time, the management server 30 transmits a new service condition notification (service charge) to the first terminal 10 (S59). On the other hand, when the lower limit of the desired range from the first terminal 10 exceeds the upper limit of the desired range from the second terminal 20, the management server 30 determines that the negotiation is unsuccessful, and the subsequent services are terminated. (Service end registration means 34). However, even if the first negotiation is unsuccessful, the management server 30 may inquire of the first terminal 10 and the second terminal 20 for another desired range, and may receive the service fee negotiation request notification again.

On the other hand, when the service provider wishes to stop the service after a predetermined time has elapsed from the start of the service, the first terminal 10 sends a service stop notification to the management server 30. Further, if the service user also wishes to stop the service thereafter, the management server 30 may receive the service stop notification from the second terminal 20. When the management server 30 receives the service stop notification from at least one of the first terminal 10 and the second terminal 20, the subsequent services are terminated (service termination registration means 34).

In this way, after a predetermined time has elapsed from the start of the service, the service stop notification is received from the service provider (first terminal 10) and the service user (second terminal 20), while both parties desire to continue the service. However, there will be an opportunity to review the service fee. Therefore, according to the matching system 1 according to the present embodiment, it is possible to select service continuation at an appropriate rate for both the service provider and the service user.

By the way, when the management server 30 receives the service stop notification from the other party from the first terminal 10 or the second terminal 20, the management server 30 does not notify that the other party has indicated the intention to stop the service, but rather negotiates the service. There may be an indication of intention, and as a result, it may be notified that the charge negotiation (pseudo charge negotiation) has ended unsuccessfully.

Specifically, when the management server 30 receives the service stop notification from the first terminal 10, the management server 30 transmits the result of the pseudo charge negotiation to the second terminal 20 in order to stop the subsequent services. Similarly, when the management server 30 receives the service stop notification from the second terminal 20, the management server 30 transmits the result of the pseudo charge negotiation to the first terminal 10 in order to stop the subsequent services. After that, the management server 30 executes the service termination process.

According to this aspect, even if the service provider (first terminal 10) indicates the intention to stop the service, the service user (second terminal 20) is informed that the negotiation is unsuccessful as a result of the pseudo charge negotiation. Notice. As a result, it is possible to conceal the intention to stop the service. Similarly, when the service user (second terminal 20) indicates the intention to stop the service, it indicates to the service provider (first terminal 10) that the negotiation has been unsuccessful as a result of the pseudo charge negotiation. As a result, it is possible to conceal the intention to stop the service.

<Reservation frame transaction process>
In the matching system 1 according to the present embodiment, the time zone (reservation frame) already reserved between the service provider and the service user (hereinafter, "first service user") is set to another service user (hereinafter, "reservation frame"). , "Second service user") can purchase (transaction). An example of the transaction process of the service reservation frame will be described with reference to FIG. Here, FIG. 6 is a flowchart showing the transaction process of the service reservation frame.

In addition, in the matching system 1 according to the present embodiment, in order to prevent the reservation party (service user) from being changed immediately before the service is implemented, the transactional period of the reservation frame is limited to a predetermined time before the service is implemented. Is preferable. The tradable period may be set by a rule commonly imposed on the members of the matching system 1, or may be set individually at the discretion of either the reservation party (for example, the service provider and the first service user). May be good.

As shown in FIG. 6, the second service user sends the schedule information of the service provider who desires the service through the third terminal (terminal indicated by reference numeral 50 in FIG. 1) of the second service user. Browse (eg, Figure 3). If the service provider has a reservation slot that can be traded, the line B is displayed on the schedule screen as shown in FIG. The second service user selects the line B displayed on the third terminal 50 (S61).

With the selection of the line B, the third terminal 50 requests the management server 30 to acquire the transaction condition information (for example, the desired minimum charge). Accordingly, the management server 30 transmits the transaction condition information to the third terminal 50. It is preferable that the management server 30 transmits the above-mentioned information (index 1) to (index 3) regarding the service provider to the third terminal 50 together with the transaction condition information. In this case, the second service user can refer to the guideline of the desired charge from each index value received from the management server 30.

When the second service user decides to purchase the reservation frame with reference to the transaction condition information displayed on the third terminal 50, the second service user inputs the desired charge information to the third terminal 50. The third terminal 50 transmits the input desired charge information to the management server 30 together with the transaction application notification of the reservation frame (S62).

When the management server 30 receives the transaction application notification and the desired charge information from the third terminal 50, these are sent to the first terminal 10 of the service provider and the second terminal 20 of the first service user who are the reservation parties at the present time. Send information about. At this time, the management server 30 may transmit the attribute information of the second service user, the photo data including the face image, and the information of (index 1) to (index 3) to at least the first terminal 10. This information is referred to when the service provider determines whether or not to accept the transaction application from the second service user.

After that, when the management server 30 receives a notification from the first terminal 10 and the second terminal 20 that the transaction at the desired charge is accepted (YES in S63), one of the reservation parties uses the first service. It stores in the storage unit that the person has changed to the second service user and that the service charge has been changed (that is, the reservation frame has been traded) (S64). This process corresponds to the reservation slot transaction registration means 36.

On the other hand, when the management server 30 receives a notification from the first terminal 10 or the second terminal 20 that the transaction at the desired charge is not accepted (NO in S63), the transaction of the reservation frame is not established. After that, if there is no other transaction application by the reservation date and time (or before the predetermined time of the reservation date and time), the reservation party will not be changed and the service will be implemented under the original conditions.

By making the reservation slot available for transaction in this way, the service provider can provide the service at a higher charge than the initial service charge. In addition, the first service user can make a profit if the transaction amount is higher than the initial service fee. Furthermore, even if the reservation is canceled due to another schedule due to the convenience of the first service user, the reservation is made with another service user (second service user). If the slot is traded, the booking party will change but the service will be implemented. As a result, the first service user can cancel the service without causing any inconvenience to the service provider. This makes it possible to provide an attractive matching system for members (service providers, service users).
