  As shown in FIG. 4B, the property that satisfies the set condition as shown in FIG. 4A belongs to each set. The property belonging to the set may be automatically performed by the processing by the set generation unit 105 or may be configured based on the operation of the information provider terminal device 2 as described later. .

  FIG. 5 is a flowchart showing the flow of user registration processing by the user using the user terminal device 3 in the present embodiment. This is because when a dedicated program is operated on the user terminal device 3, a predetermined browser program is used when the web browser program on the user terminal device 3 is used when the program is activated for the first time. What is necessary is just to implement at arbitrary timings, such as when accessing a website.

  First, in step S101, input of basic information about the user such as an ID and a password used for login is accepted.

  In step S102, input of information related to the user's property preference is accepted. This may be performed by an arbitrary method such as a method of asking a plurality of questions to the user and receiving an answer.

  Finally, in step S103, an input of information regarding funds that the user can use for property purchase is accepted, and the user registration process ends. Note that information regarding funds may be performed by any method, such as a method of asking a user a question and receiving an answer, as in the case of the above-described information regarding property preferences.

  In addition, at the time of user registration, only basic user information input in step S101 is essential, and the processing in steps S102 and S103 is performed at an arbitrary timing after the user starts using the real estate information providing system according to the present embodiment. It is good also as a structure which can do.

  Various types of information related to the user who has received an input from the user terminal device 3 through the processing as described above are recorded in the user information storage unit 110 and used for processing such as determination of a set recommended to the user.

  FIG. 6 is a flowchart showing the flow of the property registration process in the property information storage unit 111. First, in step S201, the property information acquisition unit 101 acquires basic property information. This is a configuration that accepts input of basic property information by operation of the information provider terminal device 2, or an external server (not shown) that provides real estate information, or an operation of the information provider terminal device 2 It is good also as composition which acquires basic information about a property based on.

  In step S202, the property attribute input accepting unit 102 accepts designation of attribute information from the information provider terminal device 2. This is, for example, a configuration in which attribute information that can be set for a property is presented to the information provider terminal device 2 and a selection is received from the information provider terminal device 2 or an instruction to add new attribute information is received from the information provider terminal device 2 What is necessary is just to be a possible structure.

  In subsequent step S203, the property feature vector calculation unit 103 calculates the property feature vector from the property basic information acquired in step S201 and the property attribute information received in step S202. This includes processing for performing dimension compression on basic information and attribute information, and the like, and calculates a feature vector indicating the feature of the property.

  In step S204, the candidate of the set to belong is selected based on the basic information of the property acquired in step S201, the attribute information of the property whose setting is received in step S202, the property feature vector calculated in step S203, and the like. For example, a set in which a set condition is met that matches basic information or attribute information attached to the property is extracted, and a set is set based on the degree of match between the property feature vector of the property and the set feature vector of the set. May be performed by a method such as extracting.

  In step S205, selection of a set to which the property belongs is accepted from the candidates selected in step S204. This may be performed by an arbitrary method such as a method of outputting the result of selection of candidates in step S204 to the information provider terminal device 2 and accepting the selection from the result.

  After the set to which the property belongs is determined by the above processing, in step S206, the property feature vector of the property is updated based on the set feature vector of the set to which the property belongs. In other words, this corresponds to the feedback processing of the collective feature vector to the property feature vector.

  FIG. 7 is a flowchart showing the flow of a set creation process. This is performed based on the operation of the information provider terminal device 2 by a person in charge who provides information on real estate. First, in step S301, a set condition setting is accepted. This may be done by any method such as outputting the basic information of the property or a list of attribute information already set for any property to the information provider terminal device 2 and receiving a selection from the information provider terminal device 2. .

  In step S302, a set feature vector is calculated by the set feature vector calculation means 106 based on the set condition received in step S301. Similar to the calculation of the property feature vector previously described in step S203 of FIG. 6, this includes a process of performing dimension compression on the information set as the set condition, and calculates a feature vector indicating the set characteristics. Is.

  In step S303, the candidate of the property to belong to the created set is selected. This is, for example, a method of extracting a property that matches the set condition set in step S301, and extracting a set based on the degree of match between the set feature vector of the set and the property feature vector of the property. Just do it.

  In step S304, selection of a set to which the property belongs is accepted from the candidates selected in step S303. This may be performed by an arbitrary method such as a method of outputting the candidate selection result in step S303 to the information provider terminal device 2 and accepting the selection from the result.

  After the property belonging to the set is determined by the above processing, in step S305, the set feature vector of the set is updated based on the property feature vector of the property belonging to the set. In other words, this corresponds to feedback processing of the property feature vector to the collective feature vector.

  FIG. 8 is a flowchart showing a flow of a process of recommending a set to the user. First, in step S401, the cluster generation unit 108 generates a cluster of sets. This is for clustering a set based on a set feature vector assigned to each set. Thereby, a cluster including a plurality of sets is generated. That is, the cluster includes a plurality of sets having similar characteristics.

  Subsequently, in step S402, the browsing history of the set by the user is acquired from the browsing history storage unit 113. The browsing history may be recorded in the browsing history storage unit 113 when the user browses with the user terminal device 3 after the group recommendation unit 107 recommends the group.

  In step S403, a variable considered to be important when the user browses the set is extracted from the browsing history of the set acquired by the user in step S402. This can be done by extracting the set conditions, etc. that the multiple sets included in the browsing history have in common. For example, tags such as “Single” and “Family” indicating a lifestyle suitable for the property, “ Tags indicating the surrounding environment such as “green a lot” and “riverside” can be extracted.

  In step S404, a set recommended to the user is selected. Here, the cluster generated in step S401 is compared with the variables extracted by the user in step S403 and the set that is likely to be attractive to the user is selected.

  In the present embodiment, a configuration is shown in which a cluster of a set is generated in step S401 and then compared with a variable that is regarded as important by the user. However, the present invention is not limited to this, and step S401 is not limited thereto. It is also possible to omit the generation of clusters in, compare each set with variables that the user places importance on, and select a set recommended to the user.

  In addition, referring to information related to the user such as property preferences recorded in the user information storage unit 110 in the user registration process as described above with reference to FIG. 5 and recommending a set based on the information. It is preferable to adopt a configuration that also performs.

  As described above, according to the real estate information providing system according to the present invention, information regarding various properties can be provided to the user by recommending the property in the form of a set instead of individual properties to the user. Can be provided.

  Then, by calculating the feature vectors for each property and set, and feeding them back to each other, we analyze the features of the property that cannot be expressed by simple tagging, etc., and recommend the set to the user based on that By doing so, it can be expected to recommend a set that suits the user's potential preferences.
