[0003] [Patent Document 1] JP 2023-042885 A Summary of the Invention [Problem to be solved by the invention]

[0004] In brokerage business for buying, selling or renting real estate properties (hereinafter simply "properties"), there are cases where the agent whose client is the seller or lessor of the property (hereinafter the seller agent) is different from the agent whose client is the buyer or lessee of the property (hereinafter the buyer agent). In a situation where the seller agent and the buyer agent are different, when the buyer agent delivers materials introducing the property (for example, materials containing drawings showing the layout of the property, images showing the exterior of the property, and materials containing the seller agent's obi) to the customer, the buyer agent will "change the obi" by changing the seller agent's obi in the materials sent from the seller agent to its own (i.e., the buyer agent's) obi, and then deliver the changed materials to the customer. The obi includes the name of the real estate agent, the license number for real estate transactions, the agent's address, and contact information (email address, telephone number, and name of the person in charge), etc. Conventionally, this obi change was generally done manually, which required a lot of work. [Means for solving the problem]

[0005] In one aspect, the present invention provides an information processing method comprising the steps of: transmitting image data representing a document introducing a property to be traded, including information about the publisher, which the terminal has acquired from a real estate database, from the terminal to a server; performing a re-banding process on the server to generate image data of the document in which the information about the publisher has been changed to contact information corresponding to the terminal; and notifying the server of access information for the image data after the re-banding process. According to the information processing method of this aspect, the banding of property documents is automatically changed, reducing the labor required for changing the banding. By reducing the labor required for changing the banding, agents can focus more on making proposals to customers. Thus, according to the information processing method of the first aspect, by automating the changing of the banding of property documents, it is possible to support agents in making proposals to customers.

[0006] In a preferred embodiment, the method further includes the steps of: the server collecting information on the property acquired by the terminal accessing the real estate database; the server storing, based on the information acquired from the terminal, a property ID of each property and information generated based on text information on the property in association with each other; the terminal changing a file name of the acquired image data using the property ID; and the server storing information associated with the property specified from the file name of the image data received from the terminal in association with the image data on which the banding process has been performed, and in the notifying step, the server further notifies the access destination for the information associated with the image data on which the banding process has been performed. It becomes possible to obtain a set of image data and text information representing materials introducing the property.

[0007] In another preferred embodiment, in the banding process, one of a plurality of contact data indicating contact points corresponding to the terminal is used according to the acquired image data. The information processing method according to this embodiment also makes it possible to acquire a set of image data and text information representing a document introducing the property to be traded.

[0008] In another preferred embodiment, the server further includes a step of receiving from the terminal a designation of a terminal to which the materials are to be proposed, and the server transmits, in the notification step, guide information including an access destination for the image data that has been subjected to the banding process, to the designated terminal. According to the information processing method of this embodiment, it is possible to guide properties to customers of the buyer's agent.

[0009] In another preferred embodiment, the method further comprises a step of displaying, on the terminal, of the information on the plurality of properties acquired from the real estate database, properties for which image data has already been acquired from the real estate database in a manner that makes it possible to distinguish those properties for which image data has not yet been acquired. According to the information processing method of this embodiment, it is possible to know, using the terminal, whether image data representing a document has been acquired.

[0010] In another preferred embodiment, the server further includes a step of identifying a property for which a price change has occurred when the terminal has acquired information from the database multiple times in the collecting step, a step of notifying the terminal of identification information of the identified property, and a step of displaying, on the terminal, information indicating that a price change has occurred together with the property information acquired from the server. According to the information processing method of this embodiment, the property information of the property for which a price change has occurred and the information indicating that a price change has occurred are displayed on the terminal, which can be useful in making a decision on a proposal to a customer.

Embodiments for Carrying Out the Invention

[0012] <A. Embodiment> The embodiments described below are technically preferably subject to various limitations. However, the embodiments of the present invention are not limited to the forms described below.

[0013] FIG. 1 is a diagram showing a configuration example of an information system 1 that executes the information processing method of the present invention. As shown in FIG. 1, the information system 1 includes a first terminal 10, a second terminal 20, and a business support ser The system includes a first terminal 10, a second terminal 20, a business support server 30, and a database server 40. The first terminal 10, the second terminal 20, the business support server 30, and the database server 40 are connected to a communication network NW such as the Internet by wire or wirelessly. The first terminal 10, the second terminal 20, the business support server 30, and the database server 40 communicate data with each other via the communication network NW.

[0014] The first terminal 10 is a user (hereinafter, referred to as a “buyer”) who wishes to purchase or is considering purchasing a real estate property. A specific example of the first terminal 10 is a smart Examples of the first terminal 10 include a phone, a tablet terminal, or a personal computer. Various application software such as a web browser and a mailer are pre-installed in the first terminal 10. A user of the first terminal 10 can browse various web pages and send and receive e-mails by executing these application software on the first terminal 10. Although only one first terminal 10 is shown in FIG. 1, multiple first terminals 10 may be included in the information system 1.

[0015] The second terminal 20 is owned and managed by a broker (i.e., a buyer-side agent) that proposes real estate properties to buyers, and is an information processing terminal used by employees of the buyer-side agent, etc., like the first terminal 10, the second terminal 20 is a smartphone, tablet terminal, or personal computer. Like the first terminal 10, the second terminal 20 has various application software such as a web browser and mailer pre-installed. A user of the second terminal 20 can browse various web pages and send and receive e-mails by executing these application software on the second terminal 20.

[0016] Furthermore, as described below, when the second terminal 20 uses a web browser to access the database server 40 and downloads documents related to a property, the function of converting the file name of the downloaded data according to a predetermined rule, and various other functions for facilitating the linking of information provided by the business support server 30 with information obtained from the database server 40 can be implemented, for example, as an extended function (plug-in) of the web browser. This plug-in is downloaded from the business support server 30, for example, when registering for various services provided by the business support server 30. 1 shows only one second terminal 20, a plurality of second terminals 20 may be included in the information system 1. The second terminal 20 is an example of a terminal in the present invention.

[0017] The database server 40 is a computer device that stores a real estate database DB1. The real estate database DB1 stores image data of materials related to real estate properties for which buyers are being sought. FIG. 2 is a diagram showing an example of the materials AD. The image data representing the materials AD includes JPEG data that represents an image of the property's floor plan or an image of the property's exterior. This image data is not limited to JPEG format, and may be PDF or other format data. The materials AD also include a band B of the seller's agent who is acting as an intermediary for the property that is the subject of the transaction. The various information such as the name posted on the band B of the seller's agent is an example of the information of the publisher in the present invention. The database server 40 may be managed and operated by an entity (a company, an organization, or other legal entity) different from the buyer-side trader, or may be managed and operated by the buyer-side trader.

[0018] The business support server 30 is a computer device that proposes business support services that support brokerage work by buyer-side agents to pre-registered users. In this embodiment, the user of the second terminal 20 (such as a salesman of a brokerage agent) registers in advance to use the business support service. The business support service in this embodiment includes a band replacement service that replaces the band of the seller-side agent with that of the buyer-side agent in the materials represented by the image data obtained from the database server 40. Processing is included. The business support server 30 may be managed and operated by an entity (such as a company or other legal entity) different from the buyer-side trader, or may be managed and operated by the same entity as the buyer-side trader.

[0019] Fig. 3 is a diagram showing an example of the configuration of the business support server 30. As shown in Fig. 3, the business support server 30 includes a communication device 310, a storage device 320, a processing device 330, and a bus 340 that mediates data transmission between these components.

[0020] The communication device 310 is a transmitting / receiving device connected to the communication network NW by wire or wirelessly. The communication device 310 receives data transmitted from other devices connected to the communication network NW by wire or wirelessly, and transmits data to the other devices. Specific examples of other devices that are communication partners of the communication device 310 include the first terminal 10 and the second terminal 20.

[0021] The storage device 320 includes, for example, a non-volatile storage device such as a hard disk, and a volatile storage device such as a RAM (Random Access Memory). Note that the non-volatile storage device and the volatile storage device are omitted from FIG. 3. The non-volatile storage device pre-stores a program PR1 for implementing the above-mentioned business support service. The volatile storage device is used as a work area when executing the program PR1. In this embodiment, the business support server 30 and the database server 40 are separate devices, but they may be the same device. Specifically, the real estate database DB1 may be stored in the storage device 320 possessed by the business support server 30.

[0022] The processing device 330 is a computer such as a CPU (Central Processing Unit). When the power supply (not shown in FIG. 3) of the business support server 30 is turned on, the processing device 330 reads the program PR1 from the non-volatile storage device to the volatile storage device and starts executing the program PR1. The processing device 330 operates according to the program PR1 to execute the information processing method of the present invention. The business support service is realized by executing this information processing method. This information processing method will be described below with reference to FIGS. 7 and 8. FIGS. 7 and 8 are sequence diagrams showing the flow of operations of the second terminal 20, the business support server 30, and the database server 40 in the information processing method of the present invention.

[0023] The user of the second terminal 20 executes a web browser on the second terminal 20 and logs in to the business support service. When the user logs in to the business support service, a web page (i.e., a personal page of the user of the second terminal 20) that has been assigned in advance to the user of the second terminal 20 to encourage the user to use the business support service is displayed on the second terminal 20 (SA100).

[0024] Furthermore, the second terminal 20 can access the database server 40 in response to an input operation by the user. By accessing the database server 40, the second terminal 20 executes a search process (SA110) for searching for properties that are candidates for the property to be traded. Then, the second terminal 20 executes a result display process (SA120) for displaying various information obtained by the search process.

[0025] For example, when a search is performed specifying conditions such as price, location, or age for properties that are candidates for a transaction target property, the result display process displays a list containing information about properties that meet the conditions. FIG. 4 is a diagram showing an example of a list L displayed in the result display process. As shown in FIG. 4, this list L contains a property ID, which is identification information for uniquely identifying a property, and text information about the property (in the example shown in FIG. 4, character string information representing each of the property's name, location, and price). An example of a property ID is: One example is the unique identification number (serial number) assigned to the property by the seller's agent, etc.

[0026] The properties for which text information is acquired in the search process may include properties for which image data of materials introducing the properties has already been acquired, and properties for which the image data has not yet been acquired. In the result display process, the second terminal 20 may display the former properties and the latter properties in a manner that allows the former properties to be distinguished from the latter properties. A specific example of a display manner that allows the former properties to be distinguished from the latter properties for which image data of materials introducing the properties has already been acquired, may be a manner in which the display colors of the property ID and text information are different between the former properties and the latter properties, such as displaying the property ID and text information in black characters for the former properties and displaying the information in red characters for the latter properties. In addition, as shown in FIG. 5, a manner in which the background color and foreground color of the text are inverted between the former properties and the latter properties may be considered. In the example shown in FIG. 5, image data representing materials has already been acquired for the property with the property ID of 02. In this way, the user of the second terminal 20 can quickly grasp whether materials have already been acquired for each property listed in the list.

[0027] The business support server 30 may also execute a step of analyzing the display data acquired multiple times from the second terminal 20, identifying a property for which a price change has occurred, and a step of notifying the second terminal 20 of the property ID of the identified property. Then, based on the notification from the business support server 30, the second terminal 20 may display information indicating that a price change has occurred (a pop-up M in the example shown in FIG. 6) superimposed on the list L, as shown in FIG. 6. In the example shown in FIG. 6, it is shown that a price change has occurred for a property with a property ID of 02. The pop-up M may display the date and time when the price change occurred, etc. This allows the user of the second terminal 20 to quickly grasp that there has been a price change or other change in transaction conditions. As a result, it becomes easier to make a quick and detailed proposal to the buyer. In addition to notifying whether a price change has occurred, when information items that have been added, modified, updated, etc. for a certain property are detected, this may be notified to the second terminal as necessary. In this manner, even if the database server 40 or the second terminal 20 does not have a function for determining whether the provided or received information has been updated, etc., and without the business support server 30 having to access the database server 40 sequentially or periodically, the user of the second terminal 20 can be notified that the information has been updated, etc. In addition, the user of the second terminal 20 may specify in advance the information to be notified among the updated information, and notify this to the business support server 30.

[0028] The second terminal 20, which is displaying the list described above, executes a first transmission process (SA130) of transmitting display data representing the list to the business support server 30 in response to a user instruction. This display data includes pairs of property IDs and text information published in the list. When the processing device 330 of the business support server 30 receives the display data using the communication device 310, it executes a storage process (SA140). In this storage process, the processing device 330 writes the property ID included in the received display data and the text information paired with the property ID in the storage device 320 in association with each other.

[0029] In the storage process, when the text information includes information indicating the location of the property, the processing device 330 may obtain information indicating the latitude and longitude corresponding to the location, and further associate the information or map information corresponding to the information with a pair of the property ID and the text information, and write the information to the storage device 320. The processing device 330 may generate a property browsing history by the user of the second terminal 20 based on a plurality of display data sequentially received from the second terminal 20, and store data indicating the browsing history in the storage device 320. The first transmission process and storage process described above are an example of a step of collecting property information obtained by the second terminal 20 by accessing the real estate database DB1, and a step of storing the property ID of each property and information generated based on the text information related to the property in association with each other based on the information obtained from the second terminal 20.

[0030] The user of the second terminal 20 selects a candidate property that is a candidate for the property to be traded by, for example, referring to the list displayed in the result display process (SA150). After the candidate property is selected, the second terminal 20 executes an acquisition process (SA160). In the acquisition process SA150, the second terminal 20 stores the property ID of the selected candidate property, and transmits an image transmission request including the property ID to the database server 40, thereby acquiring image data of a document related to the candidate property. The second terminal 20 then changes the file name of the acquired image data using the property ID of the candidate property, and saves the image data. In this embodiment, the second terminal 20 changes the file name of the acquired image data by embedding the property ID of the candidate property in the file name of the acquired image data.

[0031] When the second terminal 20 executes a second transmission process (SA170) for uploading the image data whose file name has been changed in the above manner to the business support server 30, the image data is transmitted from the second terminal 20 to the business support server 30. When the processing device 330 of the business support server 30 receives the image data via the communication device 310, it executes a banding process (SA180).

[0032] In this obi-changing process, the processing device 330 changes (replaces) the obi of the seller-side trader in the document represented by the image data uploaded from the second terminal 20 to information indicating the contact information corresponding to the second terminal 20 (i.e., the obi of the buyer-side trader), thereby generating image data representing the document after the obi-changing. To explain in more detail, in this obi-changing process, the processing device 330 first uses an image recognition algorithm such as AI to estimate the obi of the seller-side trader in the document represented by the image data uploaded from the second terminal 20 based on the following criteria: (a) it is located at the bottom of the document, (b) it is separated from other parts by a straight line that crosses the document, and (c) the height and shape of the separated part meet certain conditions. Then, the processing device 330 performs image recognition or the like on the part estimated to correspond to the obi based on these criteria, and if a obi of another company is detected, the processing device 330 erases the obi and inserts the obi of the buyer-side trader corresponding to the second terminal 20 into the part.

[0033] The contact information image data representing the band of the buyer-side trader may be stored in advance in the storage device 320 in association with the second terminal 20. When inserting the band represented by the contact information image data, the processing device 330 may insert the band by enlarging or reducing the band represented by the contact information image data according to the size of the area to which the band is to be inserted. In addition, multiple contact information image data representing bands of different sizes or shapes may be stored in advance in the storage device 320 in association with the second terminal 20, and the processing device 330 may select the contact information image data according to the size or shape of the area to which the band is to be inserted (in other words, according to the image data to which the band is to be inserted).

[0034] In the linking process (SA190) following the obi-changing process, the processing device 330 extracts the property ID embedded in the file name of the image data whose obi has been changed in the obi-changing process, and associates the stored text information with the image data in association with the property ID. When uploading image data from the second terminal 20 to the business support server 30, the second terminal 20 may execute a step of having the user of the second terminal 20 specify a proposal destination (a customer of the buyer-side trader) for the materials after the obi-changing. In this case, in the linking process, the processing device 330 may associate information indicating the proposal destination specified by the user of the second terminal 20 with the image data whose obi has been changed, in addition to the above-mentioned text information.

[0035] In the first notification process (SA200) following the linking process, the processing device 330 notifies the second terminal 20 of first access information for accessing the image data whose band has been changed in the band changing process, and second access information for accessing the text information associated with the image data. An example of the second access information is a URL indicating the storage location in storage device 320. An example of the second access information is a URL indicating the storage location in storage device 320 of text information associated with the image data.

[0036] The user of the second terminal 20 can view the material represented by the image data with the obi changed by clicking on the first access information, etc. Also, the user of the second terminal 20 can view the text information associated with the image data with the obi changed by clicking on the first access information, etc. In this way, the obi change is automatically performed on the property materials, reducing the burden on the buyer's side trader.

[0037] As shown in FIG. 8, after the user of the second terminal 20 checks the re-banded materials and decides on the proposed property, the user operates the second terminal 20 to cause the second terminal 20 to execute a third transmission process (SA210). In this third transmission process, the second terminal 20 transmits an email transmission request to the business support server 30 to request the transmission of an information email. The information email is an email including first access information and second access information regarding the proposed property. The email transmission request includes the property ID of the proposed property. The processing device 330 of the business support server 30 that has received the email transmission request executes a determination process (SA220). In this determination process, the processing device 330 determines whether or not a proposed destination is specified for the property ID included in the email transmission request (i.e., whether or not information indicating the proposed destination is associated with it).

[0038] If the judgment result of the judgment process is "Yes", the processing device 330 executes the second notification process (SA240). In the second notification process, the processing device 330 transmits an information email regarding the proposed property to the proposed recipient corresponding to the proposed property. For example, if the proposed recipient corresponding to the proposed property is the user of the first terminal 10, the processing device 330 transmits an information email regarding the proposed property to the first terminal 10. Note that, if information indicating the proposed recipient of the material represented by the image data is associated with the image data whose band has been changed in the band changing process, the processing device 330 may transmit the information email in the first notification process described above. The information email is an example of the information information in the present invention. By transmitting the information email, the property is automatically introduced to the customer of the buyer-side company.

[0039] On the other hand, if the determination result of the determination process is "No", the processing device 330 executes a reception process (SA230) for receiving a designation of a proposal destination of materials related to the proposed property, and then executes a second notification process. In the reception process, the processing device 330 transmits information of candidate proposal destinations to the second terminal 20, and receives proposal destination information indicating the proposal destination terminal from the second terminal 20, thereby accepting the designation of the proposal destination.

[0040] As described above, according to this embodiment, the banding of documents relating to the property is automatically changed, thereby reducing the burden on buyer-side agents.

[0041] Furthermore, according to this embodiment, whether or not information related to the property has been acquired is displayed on the second terminal 20, so it is easy to know which properties have had information requested and which have not. In this regard, if the database server 40 is operated by an entity different from the buyer-side agent and the policy of operating the business support server (for example, an organization that manages information related to real estate and makes the data available to registered real estate agents), and a policy is applied that prohibits access to information related to multiple properties that is not specified collectively or randomly downloaded (so-called crawling or scraping), an employee of the buyer-side agent would specify each property individually, download information for that property, manually change the band, and locally store the image data with the changed band. Therefore, it was difficult to manage which properties have had information requested and which have not. Furthermore, even if the person who downloaded the property information could know whether information has been requested, However, it was difficult to share the information with other employees of the buyer's company. Therefore, it was realistic to think that the information would be acquired and the banding process would be performed for the same property more than once. In other words, the management of the information used in sales activities tended to be personal. In contrast, according to this embodiment, even if the database server 40 has the above-mentioned restrictions on the access policy, it is easy to check whether the property information has been acquired and to share it with other employees.

[0042] Also, according to this embodiment, since it is possible to manage to which customer the materials after the belt replacement are sent, it becomes easy to continuously conduct detailed sales activities. In this regard, especially in real estate sales, it is said that it is important to continuously conduct sales activities for the same customer. For example, it becomes easy to grasp what kind of properties have been proposed to a certain customer in chronological order, so it becomes easy to accurately determine the content of the next proposal. By analyzing the properties to which materials have been sent for multiple customers held by the buyer-side business operator, it also becomes easy to extract information such as the relationship between the attributes of the buyer (candidate) and the property and other useful information for sales.

[0043] Thus, according to this embodiment, it is possible to support the proposal activities of the buyer-side business operator to customers.

[0044] <B: Modification Example> The above-described first embodiment may be modified as follows. In the above embodiment, replacement processing and associated processing were performed on the document originally created on the seller side and provided to the buyer side, but it may also be applied to replacement processing and associated processing on the document originally created on the buyer side (or borrower side) and provided to the seller side. In this case, the second terminal 20 in the above embodiment becomes the information processing terminal used by the seller-side business operator, and the first terminal 10 is used by the seller who is a customer of the seller-side business operator. Then, in the database server 40, instead of the real estate database DB1, image data representing materials related to the buyer or borrower of the property (for example, the purchase conditions of the real estate (layout and price of the property, etc.)) and text information related to the buyer or borrower may be stored to store the database. And, instead of the property ID, identification information uniquely indicating the buyer or borrower may be used.

[0045] As a preliminary step of sending an information email to a buyer, the business support server 30 may recommend to the user of the second terminal 20 a property that suits the preferences of the customer that the user is in charge of. In this case, when the recommended customer is selected by the user, the business support server 30 sends an information email to the customer. Specifically, the business support server 30 may calculate a score for each property, which indicates the priority when proposing the property to the customer, based on information such as the location, type, and age of the property, for each customer, and determine the customer to be recommended for each property.

[0046] The business support server 30 may have a function of supporting the arrangement of a schedule for viewing (previewing) of a property introduced in a guide email. For example, when a property for which a viewing schedule is to be arranged is selected on the second terminal 20, the business support server 30 may display a screen showing the start date and time and the end date and time of the viewing shown in FIG. 9 on the second terminal 20, and may send an email requesting the arrangement of the schedule to the person in charge of the seller of the property in response to an operation on the screen. In addition, when there are multiple properties introduced, the business support server 30 may have a function of identifying an optimal travel rule for viewing the multiple properties in order using the location information (or the customer's address), map information, and traffic information of each property, and displaying information indicating the identified travel rule on the second terminal 20.

[0047] In short, in the information system according to the present invention, the terminal retrieves image data of materials introducing the property to be traded, including information on the advertiser, from the real estate database, and displays the image data on the terminal. the step of transmitting the information of the publisher to a server, the step of performing a banding process in the server to generate image data of the material in which the publisher's information has been changed to a contact address corresponding to the terminal, and the step of the server notifying access destination information for the image data for which the banding process has been performed.
