The storage unit 32 includes, for example, a hard disk drive or the like, and stores an OS, an application (including the property information presentation program of the present invention), and the like. In the storage unit 32, a property information database (DB) 321, a user information database (DB) 322, and the like are constructed. FIG. 2 is a diagram illustrating an example of information registered in the property information database 321. The property information database 321 and the user information database 322 may be provided in another server different from the property information providing server 3.

  The property information database 321 stores a plurality of pieces of property information relating to real estate properties, real estate agent IDs (identification information for identifying the real estate agents) of real estate agents handling the real estate properties, and property IDs of the real estate properties. Is registered (stored) for each real estate property. The property information database 321 allows many pieces of property information to be managed separately for each real estate agent. Here, the property information includes the property name, appearance photograph image, property type, location information, specification information, environmental information, transaction information, and real estate agent information of the real estate property. The property type is classified into an individual house (detached house), an apartment house (a condominium or an apartment), and land. The location information is, for example, the address and position information (latitude and longitude) of the real estate. The specification information includes, for example, a building structure, a building age, a floor number, an occupied area, floor plan information, a main lighting surface, and the like. The floor plan information in the case where the property type is an apartment house includes a floor, a house number, a floor plan (including a room type of each room, a direction of an opening (a direction of a window), etc.) of each house, and the like. The transaction information includes, for example, a transaction type and a transaction condition. The transaction type is a rental property, a newly built property, or a used property. Transaction conditions for a rental property include rent, security deposit, key money, and contract period. The transaction conditions for newly built and used properties include the sale price, management costs, and reserve for repairs. The real estate agent information includes the name (for example, company name), location, telephone number, mail address, and the like of the real estate agent that handles the real estate property.

  The environmental information of a real estate property is included in the property information of the real estate property by being distinguished for each of a plurality of environmental types. Here, as described above, the environment types include sound, vibration, temperature, humidity, brightness, daylight hours, ultraviolet rays, smell, dust, ventilation, and the like. It is not necessary to register, for example, environment information of only a predetermined number of environment types (for example, at least one of sound, vibration, temperature, and sunshine duration) that is easier to handle in consideration of the gist of the present invention is registered. You may comprise so that it may be. For real estate properties for which environmental information has been acquired for each room, the environmental information (including the room type) for each room is included in the property information for the real estate property. Is included in the property information of the real estate property as an average value (may be a standard deviation value or a median value) for each environment type of the environment information of the room.

  In addition, the property name, appearance photograph image, property type, location information, specification information, transaction information, and real estate agent information of the real estate property are provided from the terminal of the real estate agent handling the real estate property, and the property information database is provided. 321 is registered. On the other hand, the environment information is registered in the property information database 321 by being provided from the environment information collection server 2. However, among the real estate properties for which property information is registered in the property information database 321, there are real estate properties for which environmental information is not provided from the environmental information collection server 2 (that is, real estate properties for which the IoT device Dn is not installed). Such environmental information of a real estate property is predicted by, for example, a supervised machine learning algorithm based on environmental information or the like acquired by an environmental sensor installed in another real estate property and registered in the property information database 321. Thus, it is registered in the property information database 321.

  The user information database 322 registers user information, search history, browsing history, and the like of each of a plurality of users who use the property information site in association with each user. The user information includes information such as a user ID (identification information for identifying the user), a password, an address (location information of a house), a telephone number, a mail address, gender, and age. The user ID and the password are user authentication information and are used for login.

  The system control unit 33 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and the CPU (computer) executes various processes according to an application operating on an operating system. I do. FIG. 3 is a diagram illustrating an example of a functional block of the system control unit 33. As shown in FIG. 3, the system control unit 33 functions as a house information acquisition unit 331, an environment information prediction unit 332, a property search unit 333, a comfort index determination unit 334, an information presentation unit 335, and the like. Here, the house information acquisition unit 331 is an example of an acquisition unit in the present invention. The environment information prediction unit 332 is an example of a prediction unit according to the present invention. Property search unit 333 is an example of search means in the present invention. The comfort index determining unit 334 is an example of a determining unit according to the present invention. The information presentation unit 335 is an example of a presentation unit in the present invention.

  The house information acquisition unit 331 acquires house information including at least one of location information and specification information of a user's house (for example, a detached house, an apartment, or an apartment) from the user terminal 1. When the user information is registered in the user information database 322, the location information of the residence of the user can be obtained from the user information. Note that the specification information of the user's residence includes, for example, a building structure, a building age, a floor number, an occupied area, and floor plan information.

  The environment information prediction unit 332 is acquired by the residence information acquisition unit 331 and at least one of the location information and the specification information of the real estate property registered in the property information database 321 and the environment information of the real estate property. Based on the house information, environmental information of the house of the user is predicted. For example, based on the location information of the real estate property registered in the property information database 321 and the location information of the user's dwelling, the environmental information prediction unit 332 extracts the real estate property in the vicinity range of the dwelling in the property information database. 321 and predicts environmental information of the specified real estate property (that is, environmental information registered in the property information database 321) as environmental information of the residence of the user. Here, the vicinity range of the house is a range (for example, a range of several meters from the house) in which a change in environmental information (particularly, sound or vibration) is expected to be small. Set arbitrarily. As a result, it is possible to quickly obtain environmental information of the house while reducing the server load.

However, even in the case of a real estate property in the vicinity of a dwelling, for example, the sunshine duration and ventilation may vary greatly depending on the surrounding environment. In such a case, the environment information predicting unit 332 determines the location information, specification information, and environmental information of the real estate property registered in the property information database 321 and the house information acquired by the house information acquisition unit 331 (in this case, , Including both the location information and the specification information of the user's house), the environment information of the user's house may be predicted by a supervised machine learning algorithm. In this case, the environment information prediction unit 332 sets the location information and the specification information of the real estate property registered in the property information database 321 as explanatory variables (input data) x _n (n = 1,..., P), Environmental information (actually measured values) of the real estate property registered in the property information database 321 is used as an objective variable (correct data) y _n (n = 1,..., P) based on the explanatory variable x _n and the parameter w. (in other words, by using the parameter w relative explanatory variable x _n) constructed prediction model (learning model) f (w, x _n) a loss (error) function l (y _n, f (w , x _n) the sum of) (i.e., l calculated for each set of x _n and _{y n (y n, f (} w, x n) the sum of)) the parameter w is adjusted so as to minimize prediction model f (w, x _n), the residence information acquired by the residence information acquisition unit 331 (of the user's residence location information and data information) of the user by entering the x? ? Stay of environmental information y (= f (w, x ):? Predictive value) is obtained. Thereby, the prediction accuracy of the environmental information of the user's residence can be improved.

Here, p is the number of data (the number of items) used in constructing the prediction model f (w, _xn ), that is, the number of registered property information (a set of location information and specification information) (in other words, (The number of property IDs) (also the number of registered environmental information). f (w, _xn ) is a function having w and _xn as variables. For example, environmental information for the location information and the specification information as the explanatory variable x ₁ is the target variable y _1. A square error, Huber error, or the like is used for the loss function ld (y _n , f (w, x _n )). The prediction model f (w, _xn ) is updated, for example, when new location information and specification information are registered, or when new environmental information is registered.

In addition, regarding the environmental information of the real estate property for which the environmental information is not provided from the environmental information collection server 2, the location information, the specification information and the environmental information of the real estate property in which the environmental information is registered, and the real estate in which the environmental information is not registered Forecast is made based on the location information and specification information of the property. In this case, the environment information prediction unit 332 sets the location information and the specification information of the real estate property in which the environment information is registered as explanatory variables (input data) x _n (n = 1,. information (found) objective variable (correct answer _{data) y n (n = 1,} ···, p) as a build predictive models based on the explanatory variable x _n and the parameter w (learning model) f (w, x _n ), and environmental information is included in the prediction model f (w, x _n ) in which the parameter w is adjusted so that the total sum of the loss functions l (y _n , f (w, x _n )) is minimized. By inputting location information and specification information x? Of a real estate property that is not registered, environmental information y? (= F (w, x _? ): Predicted value) of the real estate property is obtained.

In the present embodiment, a very large amount of property information is used, and the number of items in the property information is large. Therefore, if XGBoost is used as a supervised machine learning algorithm, highly accurate prediction can be performed. XGBoost is ensemble learning combining Gradient Boosting and Random Forests. In XGBoost, a plurality of decision trees are constructed as a prediction model f (w, x _n ), and boosting is performed to construct a new decision tree using information of the previous decision tree. I have. Specifically, a new decision tree is constructed using an error (gradient of the loss function) that could not be predicted in the immediately preceding decision tree as an objective variable. In each decision tree, the explanatory variable _xn is classified according to the condition on the way from the root to the branch, and when reaching the terminal leaf, the value given to the terminal leaf is returned as a predicted value. . Since XGBoost employs a random forest, not all explanatory variables _xn are used, but the number of explanatory variables _xn is selected at a randomly determined rate and a decision tree is constructed. You.

A prediction model f (w, _xn ) when boosting is performed t times in XGBoost is represented by the following equation (1).

Therefore, the loss function l (y _n , f (w, x _n )) in XGBoost is represented by the following equation (2).

Here, if a decision tree f _t that minimizes the sum of the loss functions l (y _n , f (w, x _n )) represented by the above equation (2) is constructed, the prediction model f (w, x _n ) Can be optimized. In XGBoost, an objective function L ^{(t) obtained} by adding a regularization term Ω (f _t ) to a loss function l (y _n , f (w, x _n )) in order to prevent so-called overfitting (overfitting ^). Will construct a decision tree f _t that minimizes the sum of The objective function L ^(t) is represented by the following equation (3).

Here, T is the depth of the tree structure, γ and λ are arbitrarily set values, and w _j is the value returned by the decision tree.

  The environment information prediction unit 332 may be configured to predict the environment information using an analysis method other than the supervised machine learning algorithm. For example, the environment information prediction unit 332 may classify the real estate property in which the environment information is registered into a plurality of groups (that is, similar location information and various types) according to an algorithm such as clustering (for example, k-means method) or principal component analysis. (The cluster to which the original information belongs). Next, the environment information prediction unit 332 calculates an average value (or a standard deviation value) of the environment information associated with each of the location information and the specification information for each of the classified groups. Next, the environment information prediction unit 332 specifies the group to which the location information and the specification information of the user's residence (or the location information and the specification information of the real estate property in which the environment information is not registered) belong. For example, the environment information prediction unit 332 calculates the center of each group based on the location information and the specification information belonging to each group, and the location information and the specification information of the user's residence (or the environment information is not registered). A group having the closest center (for example, Euclidean distance, city block distance, etc.) to the real estate property (location information and specification information) is specified. Then, the environment information prediction unit 332 predicts an average value (or a standard deviation value) of the environment information in the specified group as environment information of the user's residence (environment information of a real estate property in which no environment information is registered). I do.

  The property search unit 333 includes the environment information of the real estate property registered in the property information database 321 (for example, each of the environmental information of a predetermined number of real estate properties) and the environment of the user's residence predicted by the environment information prediction unit 332. By comparing the property information with the information, the real estate property having environment information in more favorable conditions than the environment information of the house (that is, environment information indicating a value more advantageous than the value indicated by the environment information of the house) is obtained from the property information database 321. Search for. Here, the favorable condition differs depending on the type of environment. For example, when the environment type is sound (for example, noise) or vibration (for example, vibration caused by a car traveling on a nearby road), environmental information (dB) lower than environmental information (dB) of the user's residence is favorable. (Shows a value more advantageous than the value indicated by the environment information of the user's residence). For example, when the environment type is winter temperature (for example, the average temperature in the season from October to April), environment information (° C .: average temperature) higher than the environment information (° C .: average temperature) of the user's residence. Is environmental information of favorable conditions, and when the environmental type is summer temperature (for example, the average temperature in the season from May to September), the environment is lower than the environmental information (° C .: average temperature) of the user's residence. Information (° C: average temperature) is environmental information under favorable conditions. Further, for example, when the environment type is the daylight hours, environment information (time h) longer than the environment information (time h) of the user's residence is environment information of favorable conditions.

  In addition, the property search unit 333 may search for a real estate property having a predetermined number (for example, 10) of pieces of environmental information that satisfy more favorable conditions (that is, a large difference between the pieces of environmental information). Alternatively, the property search unit 333 may search for a real estate property having favorable condition environment information whose difference from the environment information of the user's residence is larger than a preset reference value. Thereby, the property information of the real estate property whose degree of improvement from the environment information of the user's residence is larger can be promptly presented without the user's trouble. Here, the reference value is set according to the environment type. For example, when the environmental information is sound, the reference value is set to about 30 dB, when the environmental information is vibration, the reference value is set to about 10 dB, and when the environmental information is temperature, the reference value is about 5 ° C. When the environmental information is the daylight hours, the reference value is set to about one hour.

A real estate property whose environment information of the above environment types (for example, three or more environment types among the five environment types) is more favorable than the environment information of the user's residence may be searched. Alternatively, the property search unit 333 determines, for each of the plurality of environment types, whether or not the difference from the environment information of the user's residence is environment information that is larger than a preset reference value. Even if a search is made for a real estate property in which the difference between the environment information of a predetermined number (predetermined ratio) or more of environment types (for example, three or more environment types of five environment types) is larger than a preset reference value Good.

  Note that the property search unit 333 ANDs search conditions (for example, area, rent, floor plan, etc.) arbitrarily specified by the user when searching for a real estate property having environmental information that is more favorable than the environmental information of the user's residence. You can also search in addition to conditions.

  The comfort index indicator determining unit 334 determines the comfort index of the house based on the environment information of the user's house predicted by the environment information predicting unit 332. Further, the comfort index determining unit 334 determines a comfort index of the real estate based on the environmental information of the real estate searched by the property search unit 333. Here, the comfort index is, for example, based on an average value (may be a standard deviation value or a median value) of environmental information of real estate properties registered in the property information database 321 or an ideal value obtained from a questionnaire or the like. Is a value standardized (normalized) so that the range of the value indicated by the environment information falls within a predetermined range (for example, 0 to 10), and is determined for each environment type, for example. For example, calmness as a comfort index is determined based on at least one of sound and vibration, appropriate temperature as a comfort index is determined based on temperature, and exhilaration as a comfort index based on humidity is determined. Is determined, and the lighting property as the comfort index is determined based on at least one of the brightness and the sunshine duration. Furthermore, the airtightness as a comfort index may be determined based on the amount of change of each comfort index or the difference from the outside world. The calmness, appropriate temperature, exhilaration, daylighting, and airtightness can be referred to as individual evaluation values of the real estate. Further, the stability as the comfort index may be determined based on the variance (or average) of each comfort index, and the stability may be referred to as an overall evaluation value of the real estate.

  The information presenting unit 335 transmits at least a part of the information (at least the property name and the location information of the real estate property) included in the property information of the real estate property searched by the property search unit 333 to the user terminal 1 via the network NW. To be displayed to the user as search results on the property information posting page.
