Description

System for providing condition matching real estate brokerage service based on closed platform {SYSTEM FOR PROVIDING CLOSED PLATFORM BASED CONDITION MATCHING TYPE REALESTATE BROKERAGE SERVICE}

The present invention relates to a system for providing a condition matching real estate brokerage service based on a closed platform, in which at least one transaction condition is registered from a customer, and the broker provides a platform that connects with the customer when the broker has matching items compared to the holdings. do.

The Certified Brokerage Act, which is the government's monitoring system for display and advertisement of real estate brokerage targets using the Internet, is amended in 2019 and is scheduled to be implemented in 2020. Looking at the main contents of this Act, the Minister of Land, Infrastructure and Transport monitors whether the labeling and advertising for intermediary objects using the Internet comply with the labeling and advertising regulations under the Certified Brokerage Act. Submission may be requested, and necessary measures may be requested, such as confirmation of indications and advertisements suspected of violating the law, or posting of additional information, and such monitoring work can be entrusted to an institution prescribed by Presidential Decree. As suggested in the reasons for amendment of this law, the legislative purpose of this law is to prevent damage to consumers and damage the soundness of the real estate market due to unreasonable labeling and advertisement of the brokerage object in the reality that the number of real estate brokerage users through the Internet is increasing. This is a proof that various measures are needed to secure the soundness of the display and advertisement in the Internet environment in which not only real estate brokerage but also display and advertisement for various products and services is performed.

At this time, an intermediary method to eradicate false sales of real estate was researched and developed. In this regard, Korean Patent Publication No. 2020-0019311 (published on February 24, 2020) and Korean Registered Patent No. 10-1826859 ( February 8, 2018 (announcement on February 8, 2018) includes a configuration in which a real estate agent seeks the consent of the owner when uploading a holding, and the owner information, real estate status information, address, transaction type, and transaction price when the broker uploads holdings. When transaction information is entered, each configuration is disclosed to upload to the server through false sale verification.

However, despite the enactment of various laws and regulations and research and development of systems, damage caused by sharing real estate information remains. The sharing of real estate information has made it possible for many people to easily obtain the real estate information they want from remote locations, but on the one hand, the illegal sharing of false sales increases to the extent that the Internet monitoring or consignment by the state is increasing. The damage caused by it will be returned to the consumer. In the Public Brokerage Act, where there was a legislative controversy, information can be accessed by anyone on an open platform, along with the transient ad regulation, Internet monitoring issues, ambiguity and inadequacy of the term monitoring, and problems resulting from the shift of national regulation in the area of private self-regulation. The fact that it is there is the fundamental cause of mass-producing false sales. Accordingly, there is a need for research and development of a closed platform that can only be accessed by a broker who has a corresponding product to the information of each party who intends to lease, lease, sell, and buy a product.

In one embodiment of the present invention, a user who intends to sell, buy, lease and lease uploads condition information excluding unique identification information, and the broker determines that the property held by him is the same or similar to the condition information, and then contact the user. By providing a closed platform that allows false sales to be solved, legislative controversies and regulations can be resolved at once, and the publicly abused as false sales by receiving the sales information as conditional information statistically. It is possible to provide a method of providing a condition-matching real estate brokerage service based on a closed platform, which can prevent it from being shared as a fishing property even though the transaction has already been completed. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention selects any one of selling, buying, leasing and lease of real estate, and determining the balance zone, room structure, number of floors, construction year and price of the property. A user terminal that registers at least one transaction condition, including a user terminal and a storage unit that receives and stores at least one transaction condition registered in the user terminal, and when searching for at least one transaction condition from at least one intermediary terminal, the product corresponding to the search It includes a real estate brokerage service providing server including a transmission unit for transmitting the list to at least one brokerage terminal.

According to any one of the above-described problem solving means of the present invention, a user who intends to sell, buy, lease, or lease uploads condition information excluding unique identification information, and the brokerage only determines that the property held by him is the same or similar to the condition information. By providing a closed platform that allows users to contact the user after making a decision, it is possible to solve damages, legislative controversies and regulations at once, and by receiving the property information as conditional information statistically. It can prevent public abuse and prevent it from being shared as a fishing property even though the transaction has already been completed.

2 is a block diagram illustrating a real estate brokerage service providing server included in the system of Figure 1, and Figures 3 and 4 are closed platform-based condition matching real estate brokerage service implementation according to an embodiment of the present invention It is a diagram for explaining an embodiment that has been made.

Referring to Figure 2, the real estate brokerage service providing server 300, a storage unit 310, a transmission unit 320, a holding management unit 330, a providing unit 340, a member management unit 350, a map search unit ( 360), it may include a property information management unit 370 and a right identification unit 380.

A real estate brokerage service providing server 300 according to an embodiment of the present invention or another server (not shown) that operates in conjunction with at least one user terminal 100 and at least one brokerage terminal 400 based on a closed platform When transmitting a condition matching real estate brokerage service application, program, app page, web page, etc., at least one user terminal 100 and at least one brokerage terminal 400 are provided with a closed platform based condition matching real estate brokerage service. You can install or open applications, programs, app pages, web pages, and more. Also, a service program may be driven in at least one user terminal 100 and at least one intermediate terminal 400 by using a script executed in a web browser. Here, the web browser is a program that enables you to use the web (WWW: world wide web) service, and refers to a program that receives and displays hypertext described in HTML (hyper text mark-up language). For example, Netscape , Explorer, chrome, etc. In addition, the application means an application on the terminal, and includes, for example, an app that is executed on a mobile terminal (smartphone).

Referring to FIG. 2, the storage unit 310 may receive and store at least one transaction condition registered in the user terminal 100. At this time, the user terminal 100 may select any one of selling, buying, leasing, and lease of real estate, and register at least one transaction condition including the balance zone, room structure, number of floors, construction year and price of the property. . For example, if a user checks the Seoul area charter as 200 million or less and does not care about other conditions, he or she may select a lease and set it to 200 million or less and not set the conditions for the rest. At this time, in the case of jeonse, if the senior right holder is registered, the jeonse may not be recovered, so whether or not the jeonse is registered as a senior may be added as a condition. This can be stated in the request, but since it is not possible to tag and classify all tags with different conditions for each person, a tag is automatically generated based on the items stated in the request and additional tags are added as conditions. You can also register.

For example, as shown in Fig. 4d, there are only transaction conditions of transaction type, balance zone, room structure, number of floors, construction year, jeonse price, and scheduled occupancy date.User A is the condition of searching for rental property in order to confirm the right to secure jeonse. If it is the first priority, conditions such as "Confirmation of registered copies of Gapgu and Eulgu" or "In case the amount of the property minus the maximum bond amount is greater than the jeonse amount" You can also write more. Suppose that a two-story officetel B, which is located on the south and side of a 6 pyeong tower floor with a building value of 300 million, and does not generate noise between floors, came out as a charter, and that user A wants it. At this time, if the cheonsei price is 200 million and the maximum amount of the mortgage of the bank, which is a senior mortgage creditor, is 200 million, the probability of receiving the jeonse money back is extremely low even if a chonsegwon is established. User A, who suffered from interfloor noise, satisfies all the conditions and chose Officetel B. As a result of checking the registered copy, if the place where the deposit cannot be returned, it will return to the process of having to search for the house from the beginning. Accordingly, the user terminal 100 may further describe a condition desired by the user terminal 100 in the request field, which may be classified as a transaction condition and stored through a tag.

Here, the tag is an identifier for classifying transaction conditions, and refers to an identifier such as trading, jeonse, monthly rent, etc. within the transaction type of FIG. 4A. An identifier such as all balance bands, 20-, 20+, etc. can be a tag. Here, the tag is not fixed, but may be a flexible classifier that may be newly created, changed, or deleted according to the text of the registered request field. Analysis of information resources is required for data purification and classification, but there are cases in which each user cannot set the condition of the object he wants with a preset tag because the terms used by users with various background knowledge are different. many. At this time, if there is no tag (optional), most platforms create other boxes (request field) and write information that can express themselves in the other. In order to tag the described data, the present invention In an embodiment of, the words and sentences included in the other box are expressed in a vector form, and then words and sentences in the other box expressed in the vector form are clustered.

At this time, clustering is a representative unsupervised learning method that is widely applied in studies in the fields of text mining and information retrieval, and according to the clustering method, hierarchical clustering, partitional clustering, and spectral structure clustering Clustering). The most commonly used clustering algorithms are the agglomerative hierarchical clustering algorithm and the K-means algorithm, and the K-means algorithm is evaluated as an efficient clustering algorithm although its performance is lower than that of bottom-up hierarchical clustering. Accordingly, in an embodiment of the present invention, the K-means algorithm may be applied as a clustering algorithm by focusing more on efficiency than on clustering performance. Of course, the bottom-up hierarchical clustering algorithm is not excluded. In this case, the K-means algorithm is performed under the premise that K center points in the vector space can be expressed as K clusters, and in general, clusters are formed by calculating the cosine similarity of each vector. The K-means algorithm can further use various extension algorithms such as Bisecting, Antipole, and Multipole, depending on how the cluster is created.

The above-described process will be described in detail as follows. First, a morpheme analysis and stopword removal process of words and sentences described in other boxes may be performed. In order to perform K-means with words and sentences written in other boxes, the data written in other boxes must be converted into a form suitable for performing clustering. To this end, a numerical process is performed to convert words and sentences into vectors. Morphological analysis of words and sentences is performed for numerical work, and as a result, each morpheme forms the dimension of a vector. Depending on whether the corresponding morpheme is included, each vector element has a value of 1 or 0, and a morpheme analyzer can be used in this process. The second is to create a tag pool. Distance measurements and comparable criteria between other boxes in which words and sentences are written are achieved through vector multiplication. To this end, it is necessary to define a standard vector that contains information on all morphemes, and the tag pool extracted from all other boxes can be used with this standard vector. The tag pool refers to a pool that contains all tags extracted from words and sentences included in all other boxes without overlapping.

The third is the process of creating a tag hierarchy, which is created based on the previously created tag pool. A vector for generating a tag hierarchy may be assigned a vector value according to how many times there are arbitrary tags included in the same tag pool while comparing elements of the tag pool with each other. For example, a vector value is assigned according to the degree of simultaneously inputting two arbitrary tags in a word and sentence inputted in one other box in the user terminal 100. Each of the tag vectors calculated according to this method is converted into a unit vector and then clustered through K-means, and vectors having high similarity are grouped together through cluster analysis, and thus can be classified into several tag groups. And again, it is possible to create a tag hierarchy for the entire tag set by repeatedly applying the above clustering operation to each group. Finally, the tag vector needs to be calculated, and finally, through the process of creating the tag vector, all preparations for performing the clustering algorithm are completed. Through this process, a criterion for inferring how similar information each other box has to each other is established. In addition, in order to reflect the tag hierarchy in the tag vector, a value calculated based on the hierarchy structure can be used, and the vector value assigned at this time can use, for example, Leacock-Chodorow Measure, but is not limited thereto. . Since the Leacock-Chodorow Measure expresses vocabulary similarity with values from 0 to infinity, it can be applied to update the weight of the tag vector.

When all preparations for clustering are completed in this way, a new tag can be derived by tying each other box. In this case, when K-means clustering is applied to determine the first clustering K value, the number of groups as a result of clustering (K) has an important influence on the clustering performance. In most cases, K is set as a static variable and the clustering results are derived according to the number, but it is very difficult to determine a constant K value considering the characteristics of having tags in different directions due to different background knowledge of different users. It's work. Accordingly, in the method according to an embodiment of the present invention, it is possible to set different K values according to different tags according to words and sentences included in other boxes. K-means regenerate clusters repeatedly until an optimal cluster is generated. That is, once a cluster is created by K-means, the centroid value is recalculated for all clustered groups, and vector multiplication is performed on K clusters in order for all tag pools. After that, the tag pool is allocated again to the group with the largest vector product as a result of the execution, and vector product and allocation process is performed until the last tag pool. Accordingly, when a new clustering result is calculated, the process of obtaining the center value is repeatedly performed to achieve an optimal clustering state. At this time, the end point is when no change occurs when the newly formed results are compared with the previous clustering results.

When the at least one intermediary terminal 400 searches for at least one transaction condition, the transmission unit 320 may transmit a list of objects corresponding to the search to the at least one intermediary terminal 400. At this time, the intermediary terminal 400 may send a call to the user terminal 100 using the user's phone number, and the contents at this time may be recorded and transmitted to the user terminal 100 and the intermediary terminal 400. . By converting the recorded content into STT (Speech to Text) and storing it, the consumption of database resources can be reduced. The reason for recording is that there are frequent disputes between brokers and customers in recent years, but the broker's guarantee insurance is limited to 100 million per year, so even if many customers suffer damage, they are bound to receive compensation up to 100 million. In the case of planning real estate, which has recently been damaged by tens of billions, the damage amount is approaching 18 billion, but insurance companies limit it to 100 million, so hundreds of creditors with 100 million have to share it, so damage compensation cannot be properly received. Accordingly, it is to ensure that the transcript is left as text, and through this, the possibility of false sale and the possibility of fraud can be zero.

The holding management unit 330 may map and store at least one product information with the intermediate terminal 400 when registering at least one product information held by the at least one intermediate terminal 400. For example, broker A owns items that satisfy BCDE, but it is difficult to search each item on the map, so if you put BCDE, the condition of your own items, as a search term or tag, items that satisfy BCDE In order to output the list of, the holding management unit 330 receives information on the goods held by the broker.

When the product information of at least one product held by the at least one intermediary terminal 400 and at least one transaction condition registered in the user terminal 100 correspond, the providing unit 340 sends the user terminal to the intermediary terminal 400 ( 100) of information can be provided. At this time, the at least one intermediary terminal 400 registers the product information of at least one product held, and when the product information of the held product corresponds to at least one transaction condition, a property having at least one corresponding transaction condition Can be extracted and printed. If the intermediary terminal 400 does not have a product having the condition of B-C-D-E, but it is assumed that it is a brokerage of a product having the condition of B-C-D-E, this is not a proper brokering. Accordingly, it is possible to receive the information of the possessions having the conditions of B-C-D-E and to mediate corresponding thereto.

The member management unit 350 may manage the at least one intermediary terminal 400 as a member by selecting a certified agent license and an intermediary location from the at least one intermediary terminal 400. In this case, the member management unit 350 may form a block chain using at least one intermediary terminal 400 as a node. At this time, if the blockchain is composed of a public blockchain, nodes cannot be designated as all nodes remain anonymous, but if the blockchain is composed of a private blockchain, if the conditions for participation in the blockchain are set, any Even a node can become an inspection node, and information that can be inquired inside can be used only between the intermediary terminals 400 constituting the private blockchain, and the closedness of the platform can be maintained.

Blockchain is a chain-type structure in which transaction details are stored in a block and then connected. Blockchain is called a decentralized public transaction book, and transactions are processed by consensus after sharing transaction details with connected nodes. Therefore, there is no need for a central server, and this reduces server construction and management costs.Because it is shared with all nodes participating in the transaction through the blockchain, approval from each participating node is required when modifying and approving transactions, and verification is frequently performed. Forgery or hacking is virtually difficult. In addition, the blockchain can provide a variety of services transparently by decentralizing the functions used in a centralized way by using a technology that decentralizes server functions. In the current centralized service, the database server has the authority for transactions stored in the database, and since it has the authority for write and read requests, it can be handled efficiently, but if the server is hacked, a huge loss occurs. Conversely, in the case of blockchain, information necessary for transactions and transactions is recorded and shared on the distributed ledger, so information can be directly inquired from the shared node regardless of the administrator's authority. In addition, since the existing record remains on the blockchain even when the transaction is modified, any illegal activity can be identified through past history verification.

At this time, it is possible to authenticate the mutual contract relationship by using a smart contract on the blockchain. In the case of using the blockchain smart contract technology as above, even slight data changes can be sensitively processed to detect forgery and alteration. In addition, it is possible to process various events by considering the desired transaction format by using smart contracts. Therefore, the upload unit 350 according to an embodiment of the present invention uses a smart contract, which is a computer protocol for establishing, verifying, and implementing transactional contents, thereby protecting copyrights and making the distribution of digital contents transparent. I can. Here, the member management unit 350 may use a Merkle tree for data encryption of a transaction. When using a Merkle tree and a smart contract for data encryption, the member information, transaction conditions, and sharing technology of the possession and property list Can provide. Blockchain-based hashing method and smart contracts are used to provide the safety of data source protection from hacking during distribution, and can be managed without forgery such as false sales.

In addition, the real estate brokerage service providing server 300 according to an embodiment of the present invention may detect double-spending as double-spending real estate or double lease to prevent illegal transactions. At this time, double payment means making transactions more than once with one electronic money, and corresponds to illegal transactions. Currently, the blockchain adopts a method of recognizing the chain with more blocks as a valid transaction when there is a branch in the chain with which blocks are connected, but the chain of blocks including illegal transactions can be longer than the chain of normal transactions. Since the possibility exists, the length of the chain alone cannot completely prevent illegal transactions. Accordingly, in an embodiment of the present invention, a method of detecting double payment and a method of notifying another node after detection may be further used.

To this end, the real estate brokerage service providing server 300 performs transaction backtracking, and the transaction has a unique TXID, and the transaction is connected to the input and output of the double payment detection algorithm of the blockchain, so it can be referenced using the TXID. have. All transactions can be found in blocks because the connection from IN to OUT can be continuously followed by using the TXID of the transaction. At this time, if an attack is attempted to include a double payment transaction in the blockchain, the random node will have the existing blockchain and the branched blockchain created by the attacker. At the point of branching, it is usually not immediately known which is normal. When the block chain that the node has first is called Active and the branched block chain is called Forked, there is a possibility that double payment will occur only when multiple branches occur in the block chain, so double payment is checked as a prerequisite for the branch status. Run the algorithm. In order to determine whether or not to make a double payment, the first thing to check is whether the blockchain is branching. This is because there must be a branch in order for a double payment to occur. Two transactions being compared are double payment when the previous transaction's OUT TXID is the same and the current transaction's IN TXID is different. Since one output was referenced as two inputs, two or more transactions were performed with one cryptocurrency. In this case, a warning message can be propagated to notify other nodes of the occurrence of double payment.

The map search unit 360 may overlay a list of objects on the map based on location when searching for objects in at least one intermediary terminal 400. In this case, the map search unit 360 provides a list of objects based on the current location of the intermediary terminal 400, for example, may be a method of displaying the number of items for each administrative region. In addition, when a desired tag is selected, a product (for sale) having a transaction condition corresponding to the tag may be set to be searched.

The product information management unit 370 may input an address, a photo, an option item, and a request from the user terminal 100 when the product of the user terminal 100 is a sale or rental property.
