[0017] [Figure 1] 1 is a diagram showing an overall configuration of a real estate information sharing system according to an embodiment of the present invention. [Diagram 2] 2 is a functional block diagram showing the functions of the nodes constituting the real estate information sharing system according to the present embodiment. FIG. [Diagram 3] 2 is a diagram showing an example of data stored in an information storage unit in the real estate information sharing system according to the embodiment. FIG. [Figure 4] 1 is a process flow diagram showing the flow of processes executed in the nodes constituting the real estate information sharing system according to the present embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Overall structure As shown in FIG. 1, a real estate information sharing system 1 according to an embodiment of the present invention is a system in which a plurality of nodes 2 that share real estate information are configured to be able to communicate with each other via networks NW1 and NW2. The network NW1 to which each node 2 is connected is a distributed network in which the nodes 2 are directly connected to each other on an equal basis to use each other's data and functions, and mediates data exchange between the connected nodes 2. This network NW1 is realized by, for example, a P2P network (P2P = Peer to Peer). Note that the network NW1 may be a part of a network NW2 such as the Internet.

[0019] In addition, the network NW2 to which each node 2 is connected is a public communications network such as the Internet, and each node 2 can send and receive information with other nodes 2 via the network NW2, and can reflect information it possesses on websites, etc. on the network NW2.

[0020] Node 2 is a terminal used by a user of real estate information sharing system 1, has a network interface, and operates according to a P2P file sharing program. Specifically, it is realized by a terminal or device capable of inputting and outputting various types of data and transmitting and receiving data, such as a personal computer, tablet terminal, or smartphone terminal, and has an input / output unit such as an LCD display, keyboard, or touch panel display.

[0021] Users are people who handle and view information about real estate in a broad range of areas. Specifically, users include sellers of real estate, real estate agents (original agents) who act as intermediaries in the sale of real estate at the request of sellers, house manufacturers who build buildings, remodeling companies who renovate buildings, buyers of real estate, and real estate agents (client agents) who act as intermediaries in the purchase of real estate at the request of buyers. In the following explanation, users who supply real estate as a trading subject to the real estate market, such as real estate sellers and original agents, may be referred to as "suppliers." Users who provide additional services or goods to real estate, such as house builders and remodeling companies, may be referred to as "peripheral businesses." Users who receive the supply of real estate, such as real estate buyers and client search agents, may be referred to as "demandors."

[0022] ●Function configuration As shown in FIG. 2, node 2 is realized by a so-called computer or the like, and is configured into functional blocks consisting of an information storage unit 21, a sharing processing unit 22, a setting processing unit 23, a registration processing unit 24, a judgment processing unit 25, an input / output control unit 26, an information display unit 27, and a communication processing unit 28 using hardware resources such as a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and flash memory, and software resources such as a computer program executed by the CPU. <Information storage unit 21> The information storage unit 21 stores various types of information including real estate information, such as basic information, related information, transaction information, and setting information. The real estate information broadly includes information related to real estate, and at least basic information and related information constitute the real estate information.

[0023] The basic information is information specific to the real estate itself or to the real estate. The original data of this basic information is mainly held by the user, who is the supplier.

[0024] This basic information is roughly divided into first basic information and second basic information. The first basic information includes, for example, if the real estate is a piece of land, its area, location (address), shape, etc., and if the real estate is a building, its total floor area, layout, age, etc. This first basic information is usually information that is shared with other users without any particular restrictions, and is information that is expected to be the target of the first setting described later. The second basic information is, for example, information related to the interests of the purchaser of the real estate, and includes information on mortgages and accidents placed on the real estate, etc. This secondary information is usually information shared with other users in response to specific inquiries or purchase applications for a specific real estate from the other users, and is expected to be the subject of the second setting described later.

[0025] The related information is information that is associated with the real estate. The original data of this related information is mainly owned by users who are related businesses. This related information includes, for example, information related to proposals and estimates for a building to be constructed on a specific piece of land, information related to proposals and estimates for remodeling a specific building, etc. In addition, information identifying real estate that is the subject of the proposal or estimate is associated with this related information.

[0026] Of the real estate information, at least the basic information is associated with user information of a user who has registered the original basic information in the information storage unit 21 of the node 2 and who handles the real estate related to the basic information. The user assumed in this case is specifically a supplier. Note that the related information may also be associated with user information of a user who has registered the original related information in the information storage unit 21 of the node 2 and who provides the goods or services included in the related information.

[0027] The transaction information is information related to real estate transactions, and includes, for example, information related to inquiries and purchase applications from users regarding a specific real estate. Information related to inquiries and purchase applications includes personal information of the users who made the inquiries and purchase applications. In addition, the transaction information may include information related to the actual purchase transaction, such as loan establishment, purchase price, and registration.

[0028] The information storage unit 21 can also store setting information related to the sharing settings in association with various types of information. The setting information is made up of first to third sharing settings. The first setting is a setting that allows the associated real estate information to be shared without restrictions with other nodes 2. The first setting is mainly set for the first basic information of the real estate. In addition, the first setting does not have to be actively set, and information for which the second setting or third setting described below has not been set may be treated as information that can be shared without restrictions.

[0029] The second setting is a setting that allows the associated real estate information to be shared with another node 2 when a user of the other node 2 satisfies a predetermined condition. The predetermined condition here is, for example, an inquiry or purchase application for a certain real estate from a user of the other node 2. In this case, the information for which the second setting is set is shared with the user on the condition that the user has made an inquiry or purchase application. This second setting is mainly set for the second basic information of the real estate.

[0030] The third setting is a setting that does not allow sharing with users of other nodes 2. This third setting is mainly set for transaction information. Note that even if the third setting is set for transaction information, it may be possible to allow sharing only with users who are parties to the transaction. Also, among the transaction information, purchase requests and inquiries may be set so that their contents cannot be shared with third parties, but the presence or absence and number of purchase requests and inquiries may be set so that they can be shared without restrictions.

[0031] The type of information stored in the information storage unit 21 varies depending on the node 2 or the user of the node 2. That is, if the user is a supplier, the node 2 may not store related information, but may store only basic information, transaction information, and setting information. Also, if the user is a peripheral trader, the node 2 may not store basic information, but may store only related information, transaction information, and setting information.

[0032] FIG. 3 shows an example of information stored in the information storage unit 21 for each user. FIG. 3(a) shows an example of information held in the information storage unit 21 by a user who is a supplier. In this example, basic information and transaction information are stored in association with real estate identification information that identifies real estate. Among the transaction information, an inquiry / purchase application is information that requests an inquiry about second basic information about a specific real estate or makes an application to purchase the real estate, and such information includes information about the user who made the inquiry / purchase application.

[0033] Of these pieces of information, for example, a first setting is set in the first basic information constituting the basic information, and a second setting is set in the second basic information. Also, a third setting is set in the transaction information. However, as described above, even transaction information may be shareable with the users involved. Also, if the information is related to inquiries / purchase applications, the number and existence of inquiries / purchase applications may be set to be shareable with other users without restrictions.

[0034] FIG. 3(b) shows an example of information stored in the information storage unit 21 by a user who is a peripheral business operator. In this example, the related information is stored in association with real estate identification information for identifying real estate. For example, the first setting is set in the related information.

[0035] In addition, the information storage unit 21 may also register real estate information shared from other nodes 2 by the sharing processing unit 22, which will be described later. The real estate information shared from other nodes 2 and registered here is information that has been duplicated in the other nodes 2. The duplicated real estate information is associated with user information of the user who is the supplier and who holds the original real estate information, and when the real estate information is registered in the information storage unit 21 of the node 2 that has received the information, the user information of the user who holds the original real estate information is also registered in association with the real estate information.

[0036] <Shared processing unit 22> The sharing processing unit 22 shares sharable real estate information with the other node 2 in accordance with a sharing setting, based on a search request from the other node 2. In one example, the sharing processor 22 is composed of a search processor, a determination processor, and a file transfer unit. The search processing unit transmits and receives search requests between other nodes 2 via the network NW1. That is, the search processing unit receives file search requests from other nodes 2 and transmits search requests to other nodes 2. The search request is a request to determine whether or not the file to be searched is held, and when the node 2 receives a search request from another node 2, the determination processing unit determines whether or not the corresponding file is stored in the information storage unit 21. If it is determined that the corresponding file is stored in the information storage unit 21, the search processing unit notifies the node 2 that made the search request to that effect, or transmits the corresponding file to the node 2 that made the request by the file transfer unit. On the other hand, if it is determined that the corresponding file is not stored in the information storage unit 21, the search processing unit transfers the search request to another node 2 different from the request source. Note that the file is appropriately duplicated when it is shared by other nodes 2.

[0037] <Settings processing unit 23> The setting processing unit 23 executes the setting for associating the above-mentioned sharing setting with the real estate information registered in the information storage unit 21 . The setting by the setting processing unit 23 may be performed, for example, by a user arbitrarily specifying the type of sharing setting for information registered in the information storage unit 21 or for information to be registered. When registering information in the information storage unit 21, different input forms may be provided according to the type of information, and the type of sharing setting to be set for each input form may be predetermined. As a result, the predetermined type of sharing setting is set for information input from a predetermined input form.

[0038] <Registration processing unit 24> The registration processing unit 24 is a functional unit that registers various types of information in the information storage unit 21. The registration processing unit 24 receives a registration request from a user together with predetermined real estate information, and registers the received real estate information in the information storage unit 21. When there is an inquiry or purchase application for the predetermined real estate from another user, the registration processing unit 24 registers the inquiry or purchase application in association with the predetermined real estate. Furthermore, the registration processing unit 24 may register in the information storage unit 21 real estate information shared from another node 2 by the sharing processing unit 22.

[0039] <Decision processing unit 25> When a request is made from another node 2 to share real estate information for a specific real estate with the second setting set, it is determined whether the request satisfies a specific condition. For example, the specific condition is an inquiry or purchase application for the specific real estate, and if the user of the requesting node 2 is a user who has made an inquiry or purchase application for the specific real estate, the request satisfies the condition and allows the real estate information for which the second setting is set to be shared with the requesting node 2. On the other hand, if the user of the requesting node 2 is a user who has not made an inquiry or purchase application for the specific real estate, the request does not satisfy the condition and denies the sharing of the real estate information for which the second setting is set. In addition, whether or not the requesting node 2 has made an inquiry or purchase application for a particular real estate property can be identified, for example, by referring to whether or not an inquiry or purchase application by the requesting node 2 is associated with the particular real estate information in the information storage unit 21.

[0040] <Input / output control unit 26> The input / output control unit 26 controls the input / output unit included in the node 2 . The input / output control unit 26 receives a request to register real estate information from a user, for example, by controlling the input / output unit.

[0041] <Information display section 27> The information display unit 27 displays various kinds of information on the network NW2 via a website or the like. The displayed information may be information stored in the information storage unit 21, information shared by the sharing processing unit 22 from other nodes 2, or information that has been appropriately processed or edited, and the information is converted into an appropriate data format such as HTML and displayed on the website.

[0042] In one example, when the user is a supplier, the information display unit 27 displays the first basic information as real estate for sale information on the website. In another example, when the user is a neighboring business, the information display unit 27 displays information on goods and services to be provided for a specific real estate property and their estimate information. Here, when a user who is a peripheral trader displays real estate information of a specific real estate shared by a supplier on a website, the information display unit 27 also displays information about the supplier who handles the specific real estate. The supplier displayed here is, for example, a user related to the user information associated with the real estate information, and a user who possessed the original real estate information. This information display unit 27 may be configured to automatically display information about the supplier when a user of node 2 displays real estate information on a website.

[0043] <Communication processing unit 28> The communication processing unit 28 is a functional unit that transmits and receives various information via a network NW2 such as the Internet, and is realized by, for example, a browser program that executes processing according to a predetermined communication protocol. The node 2 uses this communication processing unit 28 to transmit inquiries and purchase applications for a specific real estate property to other nodes 2, and to receive inquiries and purchase applications for a specific real estate property from other nodes 2. In addition, the node 2 transmits an acquisition request for information for which the second setting is set to a specific node 2, and receives information from the specific node 2 in response to the acquisition request.

[0044] In addition, the user may use the communication processing unit 28 to develop a website on the network NW2 and make public the information he or she owns. For example, a supplier may display information about real estate he or she owns on his or her own website. Also, a related business may display information about products and items provided in association with the real estate related to the real estate information, together with the real estate information shared by the supplier, such as details and estimates of the products and items.

[0045] Furthermore, experts who perform tasks such as various contracts and registrations associated with the purchase of real estate may also participate as users in this real estate information sharing system 1. A personal computer or the like used by such an expert may be connected to the network NW1 as a node 2, and necessary information such as real estate information and personal information of a buyer may be shared with suppliers, peripheral businesses, and / or demanders regarding a contract for purchasing real estate. In this case, for example, a flag or setting indicating that the node 2 of a specific expert is a party to a specific transaction may be registered in the information identifying the node 2 of the specific expert, so that the node 2 of the specific expert can share information on the real estate that is the subject of the transaction and transaction information as a party, regardless of the settings associated with the real estate information and setting information.

[0046] Processing flow Next, an example of a process flow for sharing real estate information in the real estate information sharing system 1 will be described with reference to Fig. 4. The example in Fig. 4 shows a process flow when a given node 2 receives a search request for real estate information of a given property from another node 2. When a node 2 receives a search request for real estate information of a specific property from another node 2 (S101), the node 2 determines whether or not it holds the requested real estate information (S102). If the node 2 does not hold the relevant real estate information, the node 2 transfers the search request to the other node 2 (S104).

[0047] On the other hand, if the real estate information of the requested specific real estate is held (S102), and if the corresponding real estate information is real estate information for which the first setting is set (S103), the real estate information is shared with the requesting node 2 (S105). Note that when sharing, the target real estate information (file) is copied and transferred.

[0048] Furthermore, if the corresponding real estate information is real estate information for which the second setting has been set (S106), the judgment processing unit 25 judges whether or not the corresponding real estate information can be shared with the requesting user (S107). Whether or not the corresponding real estate information can be shared is judged based on whether or not the requesting user satisfies a predetermined condition. As described above, in one example of this embodiment, if the requesting user makes an inquiry / purchase application for a specific real estate, it is judged that the information can be shared. If it is thus judged that the information can be shared, the corresponding real estate information is shared with the requesting node 2 (S105).

[0049] Moreover, if the relevant real estate information is neither the first setting nor the second setting, but is real estate information set to the third setting (S106), it is determined that the relevant real estate information cannot be shared, and for example, a message to that effect is returned to the requesting node 2 (S108). Also, in the process of S107, if the target real estate information is real estate information set to the second setting and the user of the requesting node 2 does not satisfy a predetermined condition, it is similarly determined that the information cannot be shared (S108).

[0050] ●Examples of how users use the real estate information sharing system 1 Hereinafter, examples of how the above-described real estate information sharing system 1 is utilized by each user will be described.

[0051] <Utilization by suppliers> For example, a supplier posts real estate information about a specific real estate that the supplier owns on a website as information about properties for sale. Here, the supplier may search for information about services and things proposed by surrounding businesses for the real estate on the network NW1, and may receive such information from a node 2 that owns the information, and display the information on the website in association with the real estate information. When displaying such information in association with the real estate information, information about the user of the node 2 that shared the information may also be displayed. In addition, the number of inquiries and purchase applications for a given property may be displayed on the website in association with the given property, thereby showing the demand for the given property as a numerical value or the like.

[0052] <Use by peripheral businesses> For example, a peripheral business operator searches for real estate information that matches the goods or services that the peripheral business operator provides, and receives the relevant real estate information from a specified node 2. The peripheral business operator may create proposals and quotations for specific goods or services in accordance with the real estate information, and may post them on their own website or provide them to buyers, etc. When presenting real estate information together with proposals for goods or services, information on the real estate agent (supplier) associated with the real estate information is also displayed. The display of such information on the real estate agent may be automatically performed by executing the functions of the information display unit 27 provided in the node 2. This allows surrounding businesses to make various proposals to prospective buyers by utilizing real estate information that is being supplied to the market as properties for sale, without having to purchase the real estate.

[0053] <Utilization by consumers> Buyers can easily search for real estate that meets their desired criteria on the network NW1 and receive information on it. This allows them to, for example, negotiate with nearby businesses based on the shared real estate information, or pass on information to experts.

[0054] The real estate information sharing system 1 according to the present embodiment may be provided with a discrimination processing unit that discriminates the type of sharing setting to be set according to the type or content of real estate information input based on the type or content of the real estate information. The discrimination processing unit, for example, holds a table in which predetermined keywords are associated with types of sharing settings in advance. When real estate information is input, a keyword search is performed on the real estate information to discriminate the type of sharing setting appropriate for the input real estate information. The setting processing unit 23 sets one of the first to third sharing settings for the input real estate information based on the judgment process by this discrimination processing unit.

[0055] In the real estate information sharing system 1 according to the present embodiment described above, a platform may be provided for each user to share information and exchange information with other users. On the platform, for example, a so-called My Page may be prepared for each user, and from that My Page, the user may be able to search for and share real estate information on NW1, send and receive information and communications with each node via NW2, edit and view information stored in the information storage unit 21, and upload information to a website.

[0056] According to the real estate information sharing system 1 according to the present embodiment, users of the nodes 2 connected to the network NW1 can easily share real estate information. As a result, the efficiency of using the real estate information is improved. [Explanation of symbols]
