That is, the information providing unit 131 may provide the building owner with information such as the type of management service registered and managed by the product management module 120 as a product, a service provider provided, a service providing method, and a price. Such information may be provided through a joint purchase platform operated by the platform server 100, and may be provided to the building owner terminal 200 through a phone call, ARS, SMS, MMS, instant messenger, or the like.

5 is a view showing the screen of the landlord's terminal 200 in the one-room rental management service joint purchase platform system according to an embodiment of the present invention, for example. As shown in FIG. 5, in the one-room rental management service joint purchase platform system according to an embodiment of the present invention, the information provider 131 provides services such as stair cleaning, Internet (TV), tax records, fire insurance, and remodeling. Information such as service type and price may be provided to the landlord terminal 200 through a mobile web or a mobile app (application).

The selection input unit 132 may receive a selection of a management service to be purchased from the building owner terminal 200 . That is, the landlord can request a purchase by checking the information provided by the information providing unit 131 and selecting a management service to be purchased. At this time, the selection input unit 132 may identify the selected management service through a click or touch through a phone button, number, text, web/app, or recognition of a voice input during a phone call.

For example, on the screen shown in FIG. 5 , selection of a corresponding management service may be input by touching a “stair cleaning” part. Alternatively, in the case of using an embedded service of an instant messenger such as KakaoTalk, a selected management service may be identified by analyzing numbers or text input through the instant messenger. Meanwhile, for voice recognition in case of using a phone call, deep learning-based voice recognition and/or natural language processing technology may be used.

The counting unit 133 may count the number of selected management services to be jointly purchased. At this time, the counting unit 133 may count the number of selections during a predetermined period. For example, the number of selections for one month can be accumulated and counted, and various applications such as one week and three months can be applied.

If the counted number of selections is greater than or equal to a predetermined value, the price calculation unit 134 may calculate a discount amount according to group purchase for the management service. In this case, the predetermined value may be the number of selections cumulatively counted for a predetermined period of time, and may be an economy of scale such as 30, 50, or 100. The predetermined value may be different for each management service, and may be set according to negotiation details, contracts, and the like with a service provider when the product management module 120 registers the management service as a product.

In addition, the price calculation unit 134 may calculate a discount rate according to the counted number of selections, and apply the calculated discount rate to calculate a discount amount according to group purchase. That is, the discount amount according to the joint purchase may be set, but the discount rate may be set to increase as more building owners select the corresponding management service. In this case, the discount rate according to the counted number of selections may be stored in advance in the form of a table, and the price calculating unit 134 may calculate the discounted amount by referring to the stored table.

The payment processing unit 135 may provide the landlord terminal 200 with a payment process for the calculated discount amount. At this time, the payment method may be different from each other according to the management service. For example, in the case of stair cleaning or the Internet, a discount amount may be calculated on a monthly basis, a payment process may be provided on a monthly basis, and a total service period may be set. However, since remodeling is a one-time service, a discounted total amount may be calculated and a payment process for the calculated total amount may be provided. Here, the payment process may include all processes according to various payment services, such as account transfer, credit card, simple payment, and pay point payment.

The one-room rental management service group purchase platform system according to an embodiment of the present invention includes the configuration of the group purchase progress module 130 as described above, so that the landlord purchases management services at a discounted price according to bulk purchase. can do.

On the other hand, in the group purchase process processed by the group purchase progress module 130, if the minimum number of selections is satisfied, the group purchase proceeds, and for purchases exceeding the minimum number of selections, the discount amount according to the group purchase is individually paid. You can let the process run. Accordingly, the service provider can quickly recruit a minimum number of customers capable of providing services at a discounted price, and can continuously recruit additional customers at any time.

The mediation module 140 may transmit service request information including information on the building of the landlord who has purchased the management service to the company terminal 300 and request that the service provider execute the management service for the one-room building of the landlord. That is, the mediation module 140 plays a role of mediating so that the landlord who has purchased the management service through a joint purchase can receive the management service from the company terminal 300, and service request information including building information and purchase information. Can be generated and transmitted to the company terminal 300.

In addition, the mediation module 140 may arbitrarily allocate a manager dispatch schedule after requesting execution of the management service. That is, the quality of the management service can be improved by randomly dispatching a manager so that the manager checks the management service provision status of the service provider.

The curating module 150 may analyze management services registered in the product management module 120 and recommend management services to the building owner terminal 200 using building information and building owner information. That is, it is possible to recommend excellent management services of a service company specializing in the management of one-room buildings through curating instead of the landlord who lacks information.

More specifically, the curating module 150 uses a pre-learned curating model using building information, landlord information, and management service information, and takes the building information and landlord information of each building owner as inputs and manages services output from the curating model. can be recommended as a customized management service for each building owner.

Here, the pretrained curating model may be a model learned based on deep learning using a Convolutional Neural Network (CNN), Recurrent Neural Network (RNN), or Random Forest classifier. Depending on the embodiment, CNN and An artificial neural network model that combines long short-term memory (LSTM) RNNs can also be used.

Meanwhile, the curating module 150 of the one-room rental management service joint purchase platform system proposed in the present invention may use reinforcement learning. Reinforcement learning, also called reinforcement machine learning, is a learning method in which a computer selects an optimal action for a given state during machine learning. Reinforced machine learning gives a reward for the result of an action tailored to a given state instead of training data used in supervised/unsupervised machine learning. Computers use rewards to improve their performance.

In the present invention, by using reinforcement learning, a management service is recommended to a building owner using the result of a pre-learned curating model, and then, after a predetermined time elapses, the building owner purchases the management service recommended by the curating module 150. Compensation can be input by receiving the satisfaction level from and feeding it back to the curating model. For example, the performance of the curating model can be improved by giving positive feedback when the satisfaction level is higher than or equal to a threshold value and negative feedback when the level of satisfaction level is lower than the threshold value.

The secretary service module 160 may contact the landlord through a phone number or an instant messenger at a predetermined cycle according to a request of the landlord terminal 200, and may respond by receiving and analyzing requests from the landlord according to the contact. For example, you can actively communicate with the building owner by contacting the building owner's phone number or instant messenger once a week. The building owner can receive the secretarial service at a desired period and at a desired time. Therefore, elderly landlords who have difficulty using the latest technologies such as the Internet and applications can easily request necessary items by simply responding to instant messengers such as KakaoTalk or phone calls, and can monitor the progress of the request or the management service being used. Current status and the like can be grasped through the secretary service module 160 .

More specifically, the secretary service module 160 may analyze requests from the building owner using natural language analysis technology using deep learning, and automatically generate and provide corresponding answers according to the analysis results. In other words, by using a chatbot using deep learning-based natural language analysis technology, the building owner's requests are automatically analyzed and responses are generated and provided, so that the building owner's requests can be responded to 24 hours a day without additional labor costs. have.

The community module 170 may provide additional lifestyle information including asset management information, travel information, and health information to the building owner terminal 200 and provide an online community service to enable communication between a plurality of building owners. . That is, the community module 170 may provide online community services such as online bulletin boards and group chatting so that various landlords can easily communicate with each other. In particular, the community module 170 collects, edits, and provides asset management information, travel information, and health information targeting elderly building owners, and may connect related asset management companies, travel companies, health management companies, etc. have.
