Description

{SYSTEM FOR PROVIDING VOUCHER SHARING SERVICE FOR TENANCY IN COMMON}

The present invention relates to a system for providing accommodation rights sharing services for profitable real estate, and provides a platform for mutually exchanging or selling accommodation rights for profitable real estate in different regions.

Among profitable real estate properties, a pre-sale hotel refers to a project in which investment money is received on the condition that ownership of each room is granted to the demander through sales and registration of shares or rooms in a newly built hotel, similar to the sale of a commercial building or officetel, and the hotel is then completed on this basis. This refers to a type of hotel that entrusts the operation and management of the hotel to a professional operator and distributes a portion of the profits generated through the operation to consumers. Unlike tourist hotels subject to the Tourism Promotion Act, sale-type hotels are classified as general lodging facilities subject to the Public Health Management Act. In a sales-type hotel, the supplier sells the hotel to consumers, and the operation of the hotel is entrusted to a professional management company. Ownership is granted to each room through separate registration. At this time, returning profits through operation is not legally mandated, but is established through a contractual relationship between the seller and the buyer, and after the sale, the buyer is distributed a free accommodation voucher for each room.

At this time, methods for managing and transferring hotel accommodation rights for sale or sharing accommodation rights were researched and developed. In relation to this, the prior art, Korean Patent Publication No. 2020-0015006 (published on February 12, 2020) and Korean Publication No. In Patent No. 2018-0056121 (published on May 28, 2018), a reservation request for a room within a lodging facility is received and stored, and when a cancellation request for a reserved room is received, the reservation request and the room for which cancellation was requested are stored. Configuration for determining whether a false listing is made, providing a list of accommodations in the available state of the user terminal, receiving reservation information and deposit information from the user terminal, changing the status information of the accommodation corresponding to the reservation information in the accommodation list, When the user terminal receives a beacon signal and generates accommodation usage information, a configuration for changing and updating the accommodation status information to use is disclosed.

However, in the former case, only the configuration of reserving rooms like a hotel is disclosed, and it is not a configuration of sharing accommodation rights provided to owners of profitable real estate. In the latter case, it only discloses the configuration in which users reserve and use accommodations, and does not include selling, sharing, exchanging, or transferring accommodation vouchers like second-hand transactions. Users who own a sales-type hotel have 6 to 7 lodging vouchers, but in order to utilize them properly, they have to go to only one area, and since the area is limited, they have to make separate hotel reservations or pay money. Accordingly, research and development of a brokerage platform that prevents accommodation rights from being extinguished by intermediating exchanges or transfers between users who own accommodation rights in sales-type hotels is required.

One embodiment of the present invention provides a brokerage platform that can exchange or transfer free lodging vouchers given to each owner in profitable real estate such as sales-type hotels or living accommodations, so that the vouchers that are given to each owner but disappear because they are not used It allows value to be put to good use, provides users with the opportunity to stay at hotels all over the country as well as hotels owned by users, and creates a hotel marketplace where hotel accommodation vouchers can be shared and transferred at a low cost. A lodging voucher sharing service for profitable real estate that not only matches each user, but also verifies the validity of the accommodation voucher with the consignment operator of each profitable real estate, thereby zeroing out situations where invalid accommodation vouchers are traded, thereby increasing reliability. A delivery system can be provided. However, the technical challenge that this embodiment aims to achieve is not limited to the technical challenges described above, and other technical challenges may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention provides a sharing terminal for uploading room information of at least one profitable real estate and accommodation voucher information of a room to be shared, searching for room information and accommodation voucher information, , a shared terminal that receives accommodation vouchers by requesting sharing of accommodation vouchers, a register that uploads room information and accommodation voucher information from the shared terminal, a transmission unit that transmits room information and accommodation voucher information to the shared terminal, and sharing of accommodation vouchers in the shared terminal. It includes a shared service providing server including a transmission unit that delivers the accommodation voucher to the shared terminal when requesting a service, and a sharing unit that delivers the accommodation voucher to the shared terminal when the shared terminal approves sharing of the accommodation voucher.

According to one of the means for solving the problem of the present invention described above, by providing a brokerage platform that can exchange or transfer free lodging rights given to each owner in profitable real estate such as a sales-type hotel or living accommodation, It allows users to put to good use the value that is given but disappears because it is not used, and provides users with the opportunity to stay at hotels all over the country, not just hotels they own. By creating a hotel marketplace, they can share hotel accommodation vouchers and make them cheaper. By making it transferable, not only by matching each user, but also by verifying the validity of the accommodation voucher with the entrusted management company of each profitable real estate, reliability can be increased by zeroing out situations where invalid accommodation vouchers are traded.

In the following, the term at least one is defined as a term including singular and plural, and even if the term at least one does not exist, each component may exist in singular or plural, and may mean singular or plural. This should be self-explanatory. In addition, whether each component is provided in singular or plural form may be changed depending on the embodiment.

At least one sharing terminal 100 may be a terminal that shares accommodation vouchers using a web page, app page, program, or application related to an accommodation voucher sharing service for profitable real estate. At this time, the sharer may be the owner of the profitable real estate, but may also be the holder of the accommodation right, so it is not limited to the owner. Accommodation certificates can be bearer bonds like gift certificates, but they can also be nominated bonds or directed bonds, so in this case, the sharer may also need to provide information about the shareee or receive input from the shareee. In addition, since the information of the accommodation voucher can be checked to confirm whether the accommodation voucher is a valid accommodation voucher, the sharing terminal 100 confirms the validity of the accommodation voucher through the consignment operation terminal 500 when uploading the sharer information and the accommodation voucher information together. It may be a terminal that is granted permission to upload.

In this case, it may be a server that allows uploading to the shared terminal 100. In addition, the shared service providing server 300 is a server that registers an accommodation voucher in the shared terminal 100 and delivers it to the shared terminal 100 when the shared terminal 400 requests exchange or transfer of the accommodation voucher. You can. In addition, when the transaction is concluded through consultation or agreement between both parties, the shared service providing server 300 receives payment from the shared terminal 400 or uploads an accommodation voucher to be exchanged, and receives the accommodation voucher from the shared terminal 400. It may be a server that transmits the payment amount to the shared terminal 100 after use. In the case of exchange, the shareee may also be a co-owner who shares his or her accommodation right, but for the convenience of explaining an embodiment of the present invention, the explanation is centered on transfer, so the co-sharer is a person who shares the accommodation right, and the shareee is a person who shares the accommodation right. Defined as a ruler.

At least one shared terminal 400 may be a terminal of a shared recipient who receives accommodation rights shared using a web page, app page, program, or application related to an accommodation right sharing service for profitable real estate. At this time, the shareee may be a person who pays the payment price to share the accommodation right as described above, but in the case of exchange, he or she may be a person who registers his/her accommodation right, has its validity verified, and is granted an upload right. In this case, since validation or upload may be the same as the process of the sharing terminal 100 described above, detailed description will be omitted. The shared terminal 400 may be a terminal that receives and uses an accommodation voucher online or offline, then inputs and uploads a review.

Here, at least one shared terminal 400 may be implemented as a computer capable of accessing a remote server or terminal through a network.

Figure 2 is a block diagram for explaining the sharing service providing server included in the system of Figure 1, and Figures 3 and 4 are an embodiment of an accommodation voucher sharing service for profitable real estate according to an embodiment of the present invention. This is a drawing to explain.

Referring to Figure 2, the shared service providing server 300 includes a registration unit 310, a transmission unit 320, a delivery unit 330, a sharing unit 340, a transfer brokerage unit 350, and an exchange brokerage unit 360. ), a verification unit 370, a matching unit 380, a recommendation unit 390, a synchronization unit 391, a completion unit 393, a price guide unit 395, and a channel creation unit 397. .

The shared service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with at least one shared terminal 100, at least one shared terminal 400, and at least one entrusted device When transmitting an accommodation voucher sharing service application, program, app page, web page, etc. of a profitable real estate to the operation terminal 500, at least one shared terminal 100, at least one shared terminal 400, and at least one The consignment operation terminal 500 can install or open an accommodation voucher sharing service application, program, app page, web page, etc. for profitable real estate. Additionally, a service program may be run on at least one shared terminal 100, at least one shared terminal 400, and at least one entrusted operation terminal 500 using a script executed in a web browser. Here, a web browser is a program that allows the use of web (WWW: World Wide Web) services and refers to a program that receives and displays hypertext written in HTML (Hyper Text Mark-up Language), for example, Netscape. , Explorer, Chrome, etc. Additionally, an application refers to an application on a terminal and includes, for example, an app running on a mobile terminal (smartphone).

Referring to FIG. 2 , the register 310 may receive room information and lodging voucher information from the sharing terminal 100 . The sharing terminal 100 may upload room information of at least one profitable real estate and accommodation voucher information of a room to be shared. At this time, the room information may include information needed to use each room, such as the number of rooms, pyeong, number of beds, number of people that can stay, whether there are cooking facilities, whether there is a bathtub, etc., and the accommodation ticket information may include a serial number such as the serial number of the accommodation voucher, or, for example, For example, it may be a one-dimensional barcode or a two-dimensional barcode and a unique identification code.

The transmission unit 320 may transmit room information and accommodation voucher information to the shared terminal 400. The shared terminal 400 can check room information and accommodation voucher information, request sharing of the accommodation voucher, and receive the accommodation voucher shared. The shared terminal 400 can search for accommodation voucher information through a search term, or can search for each accommodation voucher through a map with thumbnails and prices displayed on a national map. In addition, you can search through each classification tag. For example, you can search by checking or unchecking the check box for price range, region, room type, convenience facilities, and nearby tourist attractions. At this time, you can search by adding the NOT operator to remove unwanted items from the search results. For example, if you search with the conditions A+B+C, but D, which is an unwanted search result, keeps coming up, it can be cumbersome because you have to manually select them all. Accordingly, you can set up a search by dragging the [-] icon overlaid on the unwanted search term or word among the search results or by directly entering the unwanted word into the [-] button.

The transmission unit 330 may transmit the request to the sharing terminal 100 when the shared terminal 400 requests sharing of an accommodation voucher. At this time, there are two ways to share: exchange or payment, but both methods require first checking the authenticity of the accommodation voucher. If counterfeit lodging vouchers or already used lodging vouchers are traded, the reliability of not only the sharer but also the platform according to an embodiment of the present invention is low, so new members will not be introduced to the platform, and there is a high possibility that already registered members will leave. . Accordingly, the uploaded accommodation voucher is confirmed by the consignment operator to be a valid accommodation voucher by checking the serial number or using a unique identification code, and by managing it through blockchain, it is possible to check whether it is a used accommodation voucher or a counterfeit accommodation voucher. This will be described later in the verification unit 370.

The sharing unit 340 may deliver the accommodation voucher to the shared terminal 400 when the sharing terminal 100 approves sharing of the accommodation voucher. When transferring an accommodation voucher from the shared terminal 400, the transfer brokerage unit 350 may deliver the accommodation voucher to the shared terminal 400 after payment of the amount specified by the shared terminal 100 is completed. In this case, transfer means selling the accommodation right for the amount specified by the co-owner or for the amount agreed upon. When transferring here, there are cases where it is not clear how to enter the price of each accommodation voucher. Accordingly, guidelines can be given by providing market prices taking into account the peak or off-season price of each accommodation voucher. If the market price is provided in this way and the sharer uploads an accommodation voucher that is much cheaper than the market price, a tag or icon can be attached to provide guidance on how much cheaper the accommodation voucher is than the market price.

When exchanging an accommodation voucher between the shared terminal 100 and the shared terminal 400, the exchange brokerage unit 360 provides room information of at least one profitable real estate provided by the shared terminal 400 and the room to be exchanged. Accommodation voucher information can be uploaded, and after mutual agreement between the sharing terminal 100 and the shared terminal 400 is completed, each accommodation voucher can be delivered to the shared terminal 100 and the shared terminal 400. In this case, exchange may mean exchanging the accommodation rights held by each party, that is, the sharer and the shareee. Of course, if there is a difference in market price, payment for the difference may be made.

After receiving the room information and accommodation voucher information from the sharing terminal 100, the verification unit 370 transmits the sharer information, room information, and accommodation voucher information of the sharing terminal 100 to the consignment operation terminal that consigns and operates the profitable real estate. Afterwards, the accommodation voucher information previously mapped and stored to the sharer information and room information is compared with the accommodation voucher information received from the sharing terminal 100, and if they match, the room information and accommodation voucher information can be posted. At this time, a blockchain can be used. The blockchain can be based on the pseudocode of the chain code, and the blockchain network has a three-party structure of the verification unit 370, the shared terminal 400, and the shared terminal 100. It comes true. The verification unit 370 is a full node and has all authority over the network, and the shared terminal 400 and the shared terminal 100 are light nodes and participate in the network with limited functions. .

<Block creation procedure>

Block creation is performed when the shared terminal 100 participates in the blockchain network or changes the sharer's accommodation right. ① The sharing terminal 100 participates in the blockchain network with the verification unit 370 and requests block creation when registering its information in the blockchain or changing existing information. ② When the verification unit 370 receives a registration request, it starts the block creation procedure based on the information provided by the sharing terminal 100. At this time, in order to check whether the sharer of the sharing terminal 100 already exists, it is searched whether the sharer is registered in the blockchain. ③ The verification unit 370 checks whether the sharer is registered in the blockchain at the request of the administrator terminal (not shown) and delivers this to the administrator. ④ The manager requests the government to provide information on the sharer’s accommodation rights to check whether the sharer’s information is falsified. ⑤ The government checks whether it is permissible to provide accommodation voucher information to the sharer. ⑥ The sharing terminal 100 transmits consent to provide personal information so that the user's information can be stored in the blockchain. ⑦ The government informs whether the information of the sharer has been verified. ⑧ Information about the sharer is created and stored as a block in the blockchain.

<Chaincode operation>

Chaincode can be used to confirm consent to provide personal information, search for data inside the block, create and modify blocks, and verify accommodation voucher information. Since the information on the sharer's accommodation voucher is included in personal information, a procedure is required to confirm whether the sharer consents to the information. The entity that uses the chain code is the government, which can help verify the information of the sharer. At this time, the method of obtaining consent to provide information from the sharer is to confirm consent in the form of a message or e-mail. Block creation and verification can only be performed if the sharer agrees to provide information.

The background technologies used in the above configuration are blockchain, chaincode, and Hyperledger consensus algorithm. First, blockchain is used to synchronize data to simplify complex systems or prevent confusion. The difference between existing security methods and blockchain is that by providing the same information to everyone involved in the network, even if a specific person falsifies data, it is not recognized because it is different from the information known to all members. In other words, unlike existing data hiding, it is a technology that prevents forgery through disclosure. Of course, various methods may exist in addition to the above-described methods and are not limited to the above-described methods.

The matching unit 380 registers the location of the profitable real estate held by the shared terminal 100 and the shared terminal 400, and performs matching between the shared terminal 100 and the shared terminal 400 to generate revenue. When the location of the type real estate is not located within a preset radius and the profitable real estate is located in a location not recorded in the GPS of the shared terminal 100 and the shared terminal 400, the shared terminal 100 and the shared terminal 400 ( 400) can be matched. For example, let's assume that sharer A has GPS records in Sokcho, Jeju, and Jeonju, but no records in Busan, Jinju, etc. At this time, accommodation vouchers located in Busan, Jinju, etc. can be recommended or matched to sharer A.

The recommendation unit 390 receives demographic data from the sharing terminal 100 and the shared terminal 400, matches room information and accommodation voucher information using a recommendation algorithm based on collaborative filtering, and then I can recommend it. At this time, in the case of collaborative filtering, a cold start problem inevitably occurs due to insufficient initial data. To solve this problem, in one embodiment of the present invention, collaborative filtering is performed using CGAN (Conditional Generative Adversarial Network). In addition to solving the scarcity problem that arises during implementation, the performance of recommendations can be improved by alleviating data imbalance that occurs in actual data. By using CGAN to generate virtual data similar to reality in an empty User-Item Matrix, high accuracy is expected when compared to learning only with the existing sparse matrix. In this process, the distribution of the minority class can be identified using condition vector y and data can be generated by reflecting its characteristics. Afterwards, collaborative filtering can be applied and hyperparameter tuning can contribute to maximizing the performance of the recommendation system. For comparison, traditional oversampling techniques such as SMOTE, BorderlineSMOTE, SVM-SMOTE, ADASYN and GAN can be used.

<CGAN>

The CGAN model used in one embodiment of the present invention is a model derived from the GAN model, and the learning process is the same as that of GAN. The difference from GAN is that it is possible to learn while reflecting the distribution of the original data and the characteristics desired by the user. Therefore, the data generation process can be controlled through additional information to effectively generate data under specific conditions. First, the random noise z generated by Gaussian Distribution and the minority class feature y are input to the generator to generate sample data of the minority class. The sample is input to the discriminator, and the discriminator reflects the sample If this is expressed as an objective function, it is as shown in Equation 1 below.

Looking at D(x|y), not only the sample x extracted from the original data Pdata but also the conditions of Condition Vector y were added to the discriminator. When CGAN's generator generates samples from actual data, it generates them to have the property y. The discriminator also considers y in the process of distinguishing whether the input data is real data or virtual data. With these features, one embodiment of the present invention seeks to generate data by adding features of minority classes.

<SMOTE>

SMOTE (Synthetic Minority Over-Sampling) is a method proposed to expand the data of minority class samples while overcoming the overfitting problem of ROS, which increases the number of data by randomly selecting and repeatedly adding data from the minority class. SMOTE does not replicate data as is, but uses a method of creating new samples by appropriately combining existing data. Based on the K-Nearest Neighbor algorithm targeting minority category data, new data is generated by synthesizing K numbers. SMOTE reduces the problem of overfitting because it creates new data rather than replicating data from the minority category, but the synthesized data acts as noise or the boundary of the minority class spreads close to the majority class area, creating a new majority class. Performance degradation may occur in class prediction.

<Borderline SMOTE>

Borderline SMOTE is a modified method of the SMOTE algorithm described previously. Borderline SMOTE is based on the assumption that if only samples on the borderline that separate two groups are accurately classified, other data will also be classified well. While the existing SMOTE samples all data of minority classes, Borderline SMOTE generates new samples only for minority classes, especially those samples located on the border with the majority class.

<SVM-SMOTE>

SVM-SMOTE, like Borderline SMOTE, focuses on generating new minority class samples near the boundaries between classes. However, the difference is that the border area of SVM-SMOTE is calculated by the support vector obtained using the SVM (Support Vector Machine) classifier. For imbalanced data problems, SVM-SMOTE is more efficient than other oversampling techniques and shows the best performance.

<ADASYN>

ADASYN (ADAptive SYNthetic Sampling) is a method of generating data more systematically than the SMOTE technique by determining the number of synthetic samples to be generated for a specific sample by considering the density distribution. Compared to SMOTE, it appears to generate relatively balanced data, and improves performance because it allows learning to focus on difficult-to-learn samples, but does not show great performance in terms of improving the diversity of minority classes.

<Test>

In one embodiment of the present invention, it is possible to confirm how effective it is in improving the accuracy of the model by resolving the sparsity problem that occurs when implementing collaborative filtering based on CGAN and at the same time alleviating data imbalance that occurs in real data. For comparison with various techniques, we used a model that applied collaborative filtering to existing sparse user-item data and GAN without adding oversampling techniques such as SMOTE, Borderline SMOTE, SVM-SMOTE, ADASYN, and Condition Vector. Set the set and apply collaborative filtering. Finally, the collaborative filtering recommendation performance can be compared for each methodology, and KNN and SVD can be used as collaborative filtering models. Performance evaluation for all tests can be aimed at improving the performance of the recommender system by measuring the performance of the collaborative filtering model rather than the classification accuracy of the oversampling itself.

One embodiment of the present invention may proceed according to the following procedure.

First, for effective CGAN learning, latent factor vectors consisting of user characteristics and item characteristics are derived for UserId and AttractionId, respectively. The derived User-Vector and Item-Vector are learned by applying the CGAN algorithm. Random Noise Vector z and class information called minority class are input into Conditional Vector y into the CGAN algorithm in which the data features have been learned, creating virtual data similar to the original data. This process is repeated to create a new data set so that the number of data in the minority class is equal to the number of data in the majority class. Additionally, in order to find the optimal recommendation hit rate, hyperparameter tuning of the CGAN model can be performed and a specific hyperparameter Array List can be defined. Afterwards, the cosine similarity between the existing User-Vector and Item-Vector is calculated for the created virtual User-Vector and Item-Vector, and then the sparse User-Item matrix is supplemented by replacing them with the most similar users and items. Also, during this process, new data is added to the existing dataset so that the number of samples in the minority category is the same as the number of samples in the majority category. Collaborative filtering techniques are applied to the new dataset created in this way to recommend items to users. When calculating similarity between users in collaborative filtering, Pearson Correlation Coefficient is known to show better performance than Cosine Similarity.

Therefore, when applying collaborative filtering, the Pearson correlation coefficient is used to measure similarity between users. Lastly, in order to more accurately verify the performance of the model, it is based on not only the traditional collaborative filtering model based on existing datasets, but also the commonly used oversampling techniques SMOTE, Borderline-SMOTE, SVM-SMOTE, ADASYN, and GAN algorithms. After creating data, apply it to collaborative filtering. In one embodiment of the present invention, in order to confirm the improvement in prediction power for the recommendation system, the performance can be evaluated based on the performance of the collaborative filtering model rather than the classification accuracy of the oversampling itself. In addition, collaborative filtering predictions can be made using 5-Fold Cross Validation, and evaluation can be performed using RMSE and MAE evaluation methods.

<Evaluation>

The main purpose of a recommender system is to predict the user's future interests and preferences. Accordingly, in one embodiment of the present invention, recommendation performance can be evaluated by comparing Root Mean Squared Error (RMSE) and Mean Absolute Error (MAE). At this time, in the case of RMSE and MAE, it is easy to evaluate the numerical rating, and the smaller the size of the result, the higher the prediction accuracy. Unlike general unsupervised reinforcement learning, where the accuracy of whether the prediction result is right or wrong is important, proximity is important in rating prediction, so RMSE and MAE can be used to measure the closeness of the predicted grade to the actual grade. Let's do it. If Ep is verification data, user i's actual rating for item a is ria, and the predicted rating is (tilde)ria, it can be summarized as Equation 2.

When virtual data similar to real data is generated based on deep learning and these characteristics are used in the preprocessing process to solve the multi-class imbalance problem in the recommendation system, each class is balanced by adjusting the ratio of the minority class to the majority class. It can be achieved. By generating only data for minority categories through Condition Vector y, the effect of resolving imbalance can be achieved by extracting samples equivalent to the insufficient minority category data. In addition, it can solve the limitations of existing oversampling techniques for multi-class imbalance problems. Existing random oversampling techniques can significantly reduce recommendation performance due to overfitting, may cause data overlap or additional noise, and may not be effective in high-dimensional data. Additionally, there is a possibility of generating unrealistic data by considering only a random point and its surrounding points rather than considering the overall distribution of the data. On the other hand, CGAN shows excellent performance even on high-dimensional data because it can learn to imitate data of any distribution. Lastly, in situations where data is sparse, the sparsity problem of collaborative filtering can be solved by filling in empty matrices. The sparse matrix can be supplemented by replacing the virtual user-item-rating data generated by CGAN with items most similar to actual data.

When the accommodation voucher of the shared terminal 100 is delivered to the shared terminal 400, the synchronization unit 393 transmits the information of the shared user and the accommodation voucher to the consignment operation terminal that manages the information of the shared accommodation voucher. You can save shared events for accommodation vouchers. The completion unit 395 may settle the payment amount paid by the shared terminal 400 to the shared terminal 100 when the accommodation voucher has been used in the shared terminal 400 . When the used accommodation voucher, that is, the check-in and check-out event, is registered from each consignment operation terminal 500, it is recorded as used in the block where the unique identification code is recorded, so that it can be forged with the same unique identification code. Ensure that accommodation vouchers are not traded.

When uploading an accommodation voucher from the shared terminal 100, the price guide unit 397 may search for the market price of the accommodation voucher and transmit the price to the shared terminal 100 to provide a price setting guideline. At this time, three measurements such as room occupancy rate, average room rate, and RevPAR (sales per available room) can be used to calculate the market price. The purpose of the room occupancy rate is to measure how many rooms a specific hotel has sold during a certain period of time. In other words, it is an indicator of the proportion of rooms currently for sale that are occupied by guests. The formula for calculating room occupancy is the number of rooms sold to guests divided by the number of rooms available for sale, expressed as a percentage. Therefore, a high room occupancy rate means that many rooms have been sold, so the closer it is to 100%, the better. The average room rate is the room sales amount divided by the number of rooms sold to guests. The average room rate represents a qualitative evaluation that measures how well rooms are sold to guests. Alternatively, you can use RevPAR (Revenue Per Available Room), which is calculated by dividing the room sales by the number of rooms available for sale. Considering both of these, RevPAR can also be calculated as the product of room occupancy rate and average room rate. In other words, RevPAR is an equation that combines room occupancy rate and average room rate into one indicator. RevPAR not only measures the quantity and quality of room sales simultaneously through a single performance indicator, but also implicitly expresses the management performance of a specific hotel in that it simultaneously shows supply and demand in the hotel market. Of course, in addition to the above-mentioned method, it is also possible to provide price guidelines using prices from various hotel search sites.

The channel creation unit 397 may create a chat channel between the sharing terminal 100 and the shared terminal 400 and transmit and receive chat messages between the sharing terminal 100 and the shared terminal 400.
