FIG. 3 is a diagram showing an example of functional blocks of the system control unit 33. As shown in FIG. As shown in FIG. 3, the system control unit 33 includes an environment preference information acquisition unit 331, a residence information acquisition unit 332, an environment information prediction unit 333, a property search unit 334, a comfort level index determination unit 335, an information presentation unit 336, and the like. function as Here, the environment preference information acquisition unit 331 is an example of environment preference information acquisition means in the present invention. The residence information acquisition unit 332 is an example of residence information acquisition means in the present invention. The environment information prediction unit 333 is an example of prediction means in the present invention. Property search unit 334 is an example of search means in the present invention. The comfort index determining unit 335 is an example of determining means in the present invention. The information presentation unit 336 is an example of presentation means in the present invention.

The environment preference information acquisition unit 331 acquires from the user terminal 1 environment preference information indicating the user's preference for the environment of the place of residence. The environmental preference information may be any expression as long as it indicates the user's preference for the environment of the place of residence. Concerned (sensitive to vibration), sensitive to heat, sensitive to cold, vulnerable to hot and humid weather, concerned about odors, concerned about dust, concerned about hours of sunlight, and so on. Another example of environmental preference information is a quiet place, a place with little vibration, a cool place in summer, a warm place in winter, a place that is not hot and humid, a place with little dust, a sunny place, and the like. The environment preference information may also indicate the user's preference for the environment of a particular room type room in the residence, such as a quiet bedroom, a quiet living room, a quiet study, a sunny living room, and so on. be done. The environmental preference information may be obtained from, for example, the results of a questionnaire obtained through a questionnaire page provided to the user terminal 1 from a property information site or the like. and registered in the user information database 322 .

The residence information acquisition unit 332 acquires residence information including at least one of location information and specification information of the user's residence (for example, a detached house, condominium, or apartment) from the user terminal 1 . When user information is registered in the user information database 322, the location information of the user's residence can be acquired from the user information. The specification information of the user's residence includes, for example, the building structure, the age of the building, the number of floors, the exclusive area, and the floor plan information.

The environmental information prediction unit 333 determines 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 environmental information of the real estate property, and Environmental information of the user's residence is predicted based on the residence information. For example, the environment information prediction unit 333 predicts real estate properties within the vicinity of the residence based on the location information of the real estate properties registered in the property information database 321 and the location information of the user's residence. 321, and the environmental information of the identified real estate property (that is, the environmental information registered in the property information database 321) is predicted as the environmental information of the residence of the user. Here, the neighborhood range of the residence is a range (for example, a range of several meters from the residence) where changes in environmental information (especially, sound and vibration) are expected to be small. Arbitrarily set. As a result, environmental information of the residence can be quickly obtained while reducing the server load.

However, even if the real estate property is located in the vicinity of a residence, it is conceivable that, for example, the hours of sunshine and ventilation may change significantly depending on the surrounding environment. In such a case, the environment information prediction unit 333 obtains the location information, specification information, and environment information of the real estate property registered in the property information database 321, and the residence information acquired by the residence information acquisition unit 332 (in this case, , including both location information and specification information of the user's residence), the environment information of the user's residence may be predicted by a supervised machine learning algorithm. In this case, the environment information prediction unit 333 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), Using environmental information (measured values) of real estate properties registered in the property information database 321 as objective variables (correct data) y _n (n=1, . . . , p), based on explanatory variables x _n and parameter w In other words, a prediction model (learning model) f(w, x _n ) constructed (using parameters w for explanatory variables x _n ) and a loss (error) function l(y _n ,f(w ,x _n )) (that is, the sum of l(y _n ,f(w,x _n )) calculated for each set of x _n and y _n ) is minimized. Acquired by the residence information acquisition unit 332 (location information and specification information _of the user's residence) x? (=f(w,x _? ): predicted value) is obtained. Thereby, the prediction accuracy of the environment information of the user's residence can be improved.

Here, p is the number of data (number of items) used in building the prediction model f(w, x _n ), that is, the number of registered property information (sets of location information and specification information) (in other words For example, the number of property IDs) (also the number of registered environmental information). f(w, x _n ) is a function with w and x _n as variables. For example, environmental information for the location information and specification information, which is the explanatory variable _x1 , is the objective variable _y1 . A squared error, a Huber error, or the like is used for the loss function l(y _n ,f(w,x _n )). Note that the prediction model f(w, x _n ) is updated, for example, when location information and specification information are newly registered, or when environmental information is newly registered.

Regarding the environmental information of real estate properties for which environmental information is not provided from the environmental information collection server 2, the location information, specification information, and environmental information of the real estate properties for which environmental information is registered, and the real estate properties for which environmental information is not registered. It is predicted based on the location information and specification information of the property. In this case, the environment information prediction unit 333 sets the location information and the specification information of the real estate property for which the environment information is registered as explanatory variables (input data) x _n (n=1, . . . , p), A prediction model ( _learning model) f(w _, x _n ) and the prediction model f(w, x _n ) with the parameter w adjusted so that the sum of the loss functions l(y _n ,f(w, x _n )) is minimized, the environmental information is By inputting the location information and the specification information x? of the unregistered real estate property, the environmental information y? (=f(w,x _? ): predicted value) of the real estate property is obtained.

In this embodiment, an extremely large amount of property information is used and the number of items in the property information is large. Therefore, using XGBoost as a supervised machine learning algorithm enables highly accurate prediction. XGBoost is ensemble learning that combines gradient boosting and random forests. XGBoost builds multiple decision trees as a prediction model f(w,x _n ), and uses the information of the previous decision tree to build a new decision tree for boosting. there is Specifically, a new decision tree is constructed with an error (gradient of loss function) that could not be predicted in the previous decision tree as the objective variable. In each decision tree, the explanatory variable x _n is classified according to conditions 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 the predicted value. . Note that XGBoost uses a random forest, so instead of using all the explanatory variables x _n , a decision tree is constructed by selecting the number of explanatory variables x _n at a randomly determined ratio. be.

A prediction model f(w, x _n ) 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, in order to _prevent so-called overfitting (overlearning) _, the objective function L ( _t ⁾ will construct a decision tree f _t that minimizes the sum of The objective function L ^(t) is represented by the following equation (3).

where 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.

Note that the environment information prediction unit 333 may be configured to predict environment information using an analysis method other than a supervised machine learning algorithm. For example, the environmental information prediction unit 333 divides real estate properties for which environmental information is registered into a plurality of groups (that is, similar location information and miscellaneous information) according to an algorithm such as clustering (for example, the k-means method) or principal component analysis. cluster to which the original information belongs). Next, the environment information prediction unit 333 calculates the average value (or standard deviation value) of the environment information associated with each of the location information and the specification information for each classified group. Next, the environmental information prediction unit 333 identifies a group to which the location information and specification information of the user's residence (or the location information and specification information of the real estate property for which the environmental information is not registered) belongs. For example, the environment information prediction unit 333 calculates the center of each group based on the location information and specification information belonging to each group, and calculates the location information and specification information of the user's residence (or if the environment information is not registered). location information and specification information of the real estate) to identify the group having the closest center distance (for example, Euclidean distance, city block distance, etc.). Then, the environmental information prediction unit 333 predicts the average value (or standard deviation value) of the environmental information in the specified group as the environmental information of the user's residence (environmental information of the real estate property for which the environmental information is not registered). do.

The property search unit 334 can execute either a search that does not use the environmental information of the user's residence or a search that uses the environmental information of the user's residence. Note that in any search, the property search unit 334 can search by adding search conditions arbitrarily designated by the user (for example, area, rent, floor plan, etc.) as AND conditions.

First, in the search that does not use the environmental information of the user's residence, the property search unit 334 retrieves the environmental 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 information. Based on the environmental preference information (environmental preference information indicating the user's preference for the environment of the place of residence) acquired by the preference information acquisition unit 331, the property information database 321 stores real estate properties having environmental information that matches the user's preference. Search from For example, the property search unit 334 searches real estate properties for which the value indicated by the environment information of the environment type specified from the environment preference information is more advantageous than the preset first reference value. Search as real estate properties with information. Here, the first reference value is, for example, an average value (standard deviation value, median value, or the like) 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 set according to the environment type. For example, if the environmental preference information indicates sensitivity to sound (or a quiet place), sound is specified as the environmental type from the environmental preference information, and the value (dB) indicated by the environmental information of the sound is the first reference value (for example, , 40 dB) (in this case, less than the first reference value). Also, if the environmental preference information indicates a sensitivity to vibration (or a place with little vibration), vibration is specified as an environment type from the environmental preference information, and the value (dB) indicated by the environmental information of the vibration is the first reference value ( For example, a real estate property having a value more advantageous than (in this case, a value smaller than the first reference value) than 30 dB is searched. Further, when the environmental preference information indicates that the user is sensitive to heat (or in a cool place in summer), temperature is specified as the environmental type from the environmental preference information, and the value (° C.) indicated by the environmental information of the temperature is the first reference value (for example, 30°C) (in this case, a value smaller than the first reference value) is retrieved. Further, when the environmental preference information indicates a cold sensitivity (or a warm place in winter), the temperature is specified as the environment type from the environmental preference information, and the value (° C.) indicated by the environmental information of the temperature is the first reference value (for example, , 5° C.) (in this case, a value greater than the first reference value). In addition, when the environmental preference information indicates that the sunshine hours are important (or a place with good sunlight), the sunshine hours are specified as the environment type from the environmental preference information, and the value (4h) indicated by the environmental information of the sunshine hours is A real estate property having a value (in this case, a value greater than the first reference value) that is more advantageous than the first reference value (for example, 6h) is searched.

Note that the property search unit 334 searches real estate properties for which the values indicated by the environmental information of each of the plurality of environment types specified from the environmental preference information are more advantageous than the respective first reference values, according to the user's preference. There is also a case where a search is made for a real estate property having matching environmental information. For example, when the environmental preference information indicates sensitivity to sound (or a quiet place) and sensitivity to vibration (or a place with little vibration), sound and vibration are specified as the environment type from the environmental preference information, and the environmental information of the sound. is a value (dB) that is more advantageous than the first reference value (e.g., 40 dB), and the value (dB) that the environmental information of the vibration indicates is the first reference value (e.g., 30 dB). A real estate property that is a value is searched (similarly when there are three or more environment types).

Further, when the environmental preference information indicates the user's preference for the environment of a room of a specific room type, the property search unit 334 retrieves the environmental information of the real estate property registered in the property information database 321 and the environmental preference information. , the property information database 321 is searched for a real estate property having environmental information that matches the user's preferences regarding the environment of the room of the specific room type. In this case, for example, the property search unit 334 determines that the environment type specified from the environment preference information and the value indicated by the environment information of the room type specified from the environment preference information is a value more advantageous than the first reference value. A certain real estate property is searched for as a real estate property having environment information that matches the taste of the user. Accordingly, it is possible to quickly present property information of a real estate property having environmental information that matches the user's preference regarding the environment of a room of a specific room type without requiring the user's trouble. For example, when the environmental preference information indicates a quiet bedroom, sound is specified as the environment type from the environmental preference information, the bedroom is specified as the room type from the environmental preference information, and the environmental information of the sound in the bedroom is specified. Properties whose value (dB) is more favorable than the first reference value (eg, 40 dB) are searched. Alternatively, for example, when the environmental preference information indicates a quiet bedroom, sound and vibration are specified as the environment type from the environmental preference information, and the bedroom is specified as the room type from the environmental preference information, and the sound in the bedroom is specified. The value (dB) indicated by the environmental information is a value more advantageous than the first reference value (e.g., 40 dB), and the value (dB) indicated by the environmental information for the vibration in the bedroom is the first reference value (e.g., 30 dB ) are retrieved.

Note that the property search unit 334 searches for real estate properties that have a predetermined number (for example, 10) of environmental information with a larger difference between the value indicated by the environmental information of the environment type specified from the environmental preference information and the first reference value. can be searched. Alternatively, the property search unit 334 searches for a real estate property having environmental information in which the difference between the value indicated by the environmental information of the environment type specified from the environmental preference information and the first reference value is greater than a preset second reference value. You may Here, the second reference value is set according to the environment type. For example, if the environmental information is sound, the second reference value is set to about 30 dB; if the environmental information is vibration, the second reference value is set to about 10 dB; If the reference value is set to about 5° C. and the environmental information is the hours of sunshine, the second reference value is set to about 1 hour.

Next, in the search using the environmental information of the user's residence, the property search unit 334 combines the environmental information of the real estate property registered in the property information database 321 with the environmental preference information acquired by the environmental preference information acquisition unit 331. , and the environmental information of the user's residence predicted by the environment information prediction unit 333, environmental information that has environmental information that matches the user's preference and has better conditions than the environmental information of the user's residence ( That is, the property information database 321 is searched for a real estate property having environmental information indicating a more advantageous value than the value indicated by the environmental information of the residence. Here, favorable conditions differ depending on the type of environment. For example, if the environment type is sound (e.g., noise) or vibration (e.g., vibration caused by a car passing on a nearby road), environment information (dB) that is lower than the environment information (dB) of the user's residence is favorable environment information. (Indicates a value that is more advantageous than the value indicated by the environmental information of the user's residence). Further, for example, if the environment type is winter temperature (for example, the average temperature of the season from October to April), the environment information (°C: average temperature) higher than the environment information (°C: average temperature) of the user's residence is environment information with favorable conditions, while if the environment type is summer temperature (for example, the average temperature of the season from May to September), the environment is lower than the environment information (°C: average temperature) of the user's residence The information (°C: average temperature) becomes environmental information with favorable conditions. Further, for example, if the environment type is sunshine hours, the environment information (time h) longer than the environment information (time h) of the user's residence is the environment information with favorable conditions. For example, the property search unit 334 searches for environmental information that matches the user's preference (that is, environmental information of an environment type specified from the environmental preference information) among the environmental information of real estate properties registered in the property information database 321, By comparing the environmental information of the user's residence that matches the user's preferences (that is, the environmental information of the environment type specified from the environmental preference information), the environment type specified in the real estate property The property information database 321 is searched for a real estate property in which the value indicated by the environmental information is more advantageous than the value indicated by the environmental information of the environment type specified by the residence of the user. Accordingly, it is possible to quickly present property information of a real estate property having environment information that matches the user's preference in comparison with the environment of the user's residence without requiring the user's trouble.

Note that the property search unit 333 may search for a real estate property having a predetermined number (for example, 10 items) of environmental information with better conditions (larger difference in environmental information of the specified environment type). good. Alternatively, the property search unit 333 may search for a real estate property having favorable environmental information whose difference from the environmental information of the environment type specified by the user's residence is greater than a preset second reference value.

The comfort level index determination unit 335 determines the comfort level index of the real estate property searched by the property search unit 334 based on the environmental information of the real estate property. Further, when the environment information of the user's residence is predicted by the environment information prediction unit 333, the comfort index determination unit 335 determines the comfort index of the residence based on the environment information of the user's residence. Here, the comfort index is a value that is standardized (normalized) so that the range of values indicated by the environmental information falls within a predetermined range (eg, 0 to 10) with reference to the above-described first reference value, for example. Yes, 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 refreshment is determined as a comfort index based on humidity. is determined, and daylighting as a comfort index is determined based on at least one of brightness and sunshine hours. Furthermore, airtightness as a comfort index may be determined based on the amount of change in each comfort index or the difference from the outside world. Calmness, appropriate temperature, freshness, daylighting, and airtightness can be said to be individual evaluation values of a real estate property. Also, the stability as a comfort index may be determined based on the variance (or average) of each comfort index, and the stability can be said to be the comprehensive evaluation value of the real estate property.

The information presentation unit 336 transmits at least part of the information (at least the property name and location information of the real estate property) included in the property information of the real estate property searched by the property search unit 334 to the user terminal 1 via the network NW. It is presented to the user by displaying it as a search result. In the search results when the environmental information of the user's residence is not used, the information presenting unit 336 displays the environmental information of the real estate property searched by the property searching unit 334 that matches the user's preference (that is, environmental preference environment information of the environment type specified from the information) may be presented to the user. Alternatively, in the search result when the environmental information of the user's residence is not used, the information presentation unit 336 displays the environmental information of the real estate property searched by the property search unit 334 based on the environmental information that matches the user's preference. The determined comfort index (or combination of environmental information and comfort index) may be presented to the user. As a result, the environmental information of the real estate having the environmental information that matches the user's preference can be conveyed to the user in an easy-to-understand manner in the form of the comfort index. In addition, in the search result when the environment information of the user's residence is not used, the information presenting unit 336 displays the first reference It is preferable to present the user with improvement degree information indicating the degree of improvement from the value. This allows the user to grasp at a glance how much the environmental information of the real estate property having the environmental information that matches the user's preference is improved with respect to the first reference value.
