This enables the user of the property information site to search for a desired property. Patent Document 1 below is cited as a document disclosing a conventional technique related to such a property information site. In the conventional technology described in Patent Document 1, information on vacant properties that satisfy search conditions set by the user is presented.

JP 2018-120529 A

In the prior art disclosed in Patent Document 1, when searching for a property desired by a user, it is necessary to set search conditions for narrowing down the specifications of the property one by one. The search condition is set if it is necessary for the specification of the property to be found, and is not set if it is not necessary. Search conditions tend to be set as "necessary" for the time being, even for conditions that are desirable but not essential. A situation arises in which there is less information available. Conversely, if the number of items set as "necessary" is reduced in order to increase the amount of property information to be obtained, the amount of property information increases, but there is a problem that the number of property information with few conditions constituting the specifications increases.

The present invention provides a mechanism for extracting an appropriate amount of property information by making adjustments so that property information is not narrowed down or increased more than necessary when setting search conditions.

The present invention specifies essential conditions, desired conditions, and/or unnecessary conditions for change conditions for which property specifications are desired to be changed, generates search conditions for property search based on the change conditions, and satisfies the search conditions. It is characterized by searching for and identifying properties.

According to the present invention, change conditions used for searching are acquired from a change condition candidate database that records candidates for change conditions for which property specifications are desired to be changed, and necessary conditions and desired conditions and/or unnecessary conditions are obtained for the change conditions. It is characterized by specifying, generating a search condition for property search based on the changed condition, and searching for and specifying a property that satisfies the search condition.

In order to present the property information of this embodiment, the database DB contains property information, ie, address, name, specifications (age, size, floor plan, incidental equipment, etc.) for each property. Details will be described later. ) are stored as, for example, the property information database 20 described later. These information can be replaced with information collected by searching on the Internet. In the property information search system, when a user using a terminal device T starts searching for a property, a transmission request for a condition setting page is sent from the terminal device T via the network NW in response to the user's operation. It is sent to the information providing server SV. The condition setting page is a page for setting search conditions when the user searches for properties. The terminal device T is, for example, a personal computer, a smart phone, or a tablet terminal. Network NW is, for example, the Internet. Upon receiving the transmission request, the system control unit of the information providing server SV presents the terminal device T with candidates for change conditions. Candidates for change conditions are candidates for change conditions that the user expects for a new property. ” and “Quietly” are information for specifying the conditions for which the specification of the reference property (for example, the property in which the user is currently living) is desired to be changed.

Here, the "specification (also referred to as "spec")" is information indicating the characteristics of the property. The specifications consist of information representing various conditions such as type (detached house, condominium, apartment), rent, sales price, building age, floor plan, size, opening direction, auto-lock, resident janitor, and unit bath. The change condition is a condition for specifying a new property that satisfies the conditions requiring a change, ie, a property that satisfies the difference in specifications, among the specifications of the reference property. In addition, the specification of the property where the user is currently living is hereinafter referred to as "current state".

As shown in FIGS. 2A, 2B, and 2C, the database DB includes a change condition candidate database 10, a property information database 20, and a preference condition candidate database 30. FIG.

Candidates for change conditions are registered in the change condition candidate database 10 in association with candidate IDs that identify the candidates. In addition to the conditions equivalent to the improvement of the current conditions, the change conditions can set new conditions that are not included in the current conditions, such as "want to auto-lock" and "resident janitor". can.

The property information database 20 contains property information about vacant properties that can be moved in immediately and scheduled vacancies that will be available in the near future, but it is also possible to store property information about occupied properties whose move-in date is undecided. A property ID and property information are associated with each property. This property information includes information useful for property searches, such as property type (condominium, apartment, detached house), property name, location, rent, floor plan, size, age of building, number of floors, and free comments that indicate the characteristics of the property. is set.

In the preference condition candidate database 30, information that is a candidate preference condition is registered in association with a condition ID. Conditions such as "property on the first floor", "second floor or above", "top floor", "corner room", etc. are set as the preference condition candidates. These candidates are candidates for property conditions desired by the user searching for a new property as more specific conditions than change conditions.

The operation according to the present invention will be described with reference to the flow chart of FIG. Upon receiving the condition setting page transmission request from the terminal device T, the system control unit of the information providing server SV reads out the change conditions from the change condition candidate database 10 and transmits the read result to the terminal device T. FIG. The terminal device T displays the received change conditions and presents them to the user (step S1). The terminal device T that has received the change condition candidates displays the received change condition candidates as a candidate display 40 on the display section of the terminal device T, as illustrated in FIG.

In step S<b>1 , the system control unit may select a change condition candidate to be transmitted based on the search history of the user who has transmitted a request to search for properties with changed specifications. Further, candidate change conditions based on the user's search history may be added to the candidate change conditions to be transmitted. When presenting the change condition candidates, the system control unit may also present a question such as "Why do you want to move?" Furthermore, as a change condition, for example, the degree of change may be presented in addition to the item itself as the change condition. By presenting such change conditions, the system control unit can prompt the user to make a selection.

The user selects a desired change condition while viewing the candidate display 40 . The system control unit transmits the selection result to the information providing server SV via the network NW. The system control unit acquires the transmitted change condition selection result (step S2).

When the system control unit acquires the transmitted selection result of the change condition, the system control unit performs a process of determining property information that serves as a reference. The property information corresponding to the property where the user who uses the terminal device T to which the selection result of the change condition is currently resides is acquired (step S3). It may be a virtual object. The property information consists of an address, name and specifications regarding the property.

In step S3, the system control unit transmits to the terminal device T a condition setting page including an input field for inputting at least one of the name and address of the property where the user currently resides. The input field 41 is displayed on the terminal device T as part of the condition setting page, as illustrated in FIG. 4(b). Information indicating, for example, the name and address of the property entered using the input field 41 is transmitted by the terminal device T to the information providing server SV. Accordingly, the system control unit searches the property information database 20 for a property corresponding to the received name and address using the transmitted information. Property information that serves as a reference is composed of an address, name, and specifications regarding the property. Note that the reference property information does not necessarily have to correspond to the property that the user is currently living in. It may be another real property or a virtual property for which the user creates property information. or virtual identification information can be set instead of the name.

Here, when the reference property is a room in an apartment, and the name and/or address (including the room number) of the apartment is input using the input field 41, the system control unit displays the input name and / Or the property information database 20 is referred to and searched for the property information corresponding to the address. The system control unit transmits to the terminal device T a condition setting page including property information hit as a result of the search. This property information is displayed on the terminal device T as a property display 42 as shown in FIG. 4(c). As exemplified in FIG. 4(c), when a plurality of properties correspond to the reason that the number of floors and room numbers are not specified, a specific property is selected on the property display 42 to be selected. Information to that effect is transmitted to the information providing server SV. Based on the received selection result, the system control unit refers to the property information database 20 or the cache information corresponding to the property display 42 and acquires the corresponding property information.

After that, the system control unit transmits the obtained property information to the terminal device T. FIG. This property information is displayed on the terminal device T as a property display 43, as illustrated in FIG. 4(d). When transmitting property information, the system control unit also includes data of area selection items that are operated when specifying an area to be searched for a new property, as illustrated in FIG. 4(d). to send. Further, the system control unit is operated when instructing to search for a new property based on the selection result of the change condition transmitted in step S2 and the reference property information acquired in step S3. The data of the search result request button 50 is also transmitted as part of the condition setting page.

As a result, the user of the terminal device T on which the property display 43 and the search result request button 50 shown in FIG. (See step S3) If you want to search for a new property based on and, first, select one of the area selection items exemplified in FIG. 4D to set the search area. The terminal device T is basically set with a search area corresponding to a reference object or geographic information acquired by the GPS function of the terminal device T, but the area can be reselected. After that, the search result request button 50 is operated. As a result, the terminal device T transmits a search request for a new property to the information providing server SV based on the selection result of the change condition and the property information indicating the reference property (that is, the property that the user is currently living in). do. That is, a request for a new property search in which the user's needs for properties are reflected as selection of change conditions is transmitted to the information providing server SV.

Returning to FIG. 3, after acquiring a new property search request in response to the operation of the search result request button 50, the system control unit performs a Search for That is, the system control unit generates a search condition that satisfies the selection result of the change condition for the reference property information (step S4). Note that when a plurality of change conditions are selected, the system control unit generates search conditions that satisfy each of the plurality of change conditions for the reference property information. In this case, even if there are a plurality of change conditions, the system control unit can extract property information indicating a property that better satisfies the user's wishes (needs) reflected in the change conditions. The system control unit searches the property information database 20 using the generated search conditions (step S5). The system control unit acquires the property information corresponding to the property that satisfies the change condition with respect to the specification of the reference property as the search result of step S5. For example, if the current room size is 70 square meters, the rent is 200,000 yen, and "wide" and "cheap" are set as the change conditions, the system control unit will set the room size to exceed 70 square meters, Search for properties with a rent of less than 200,000 yen and other specifications that are above the current situation.

Next, the system control unit determines the display order of the properties indicated by the acquired property information, such that the higher the degree of satisfaction of the selected change condition, for example, the larger and cheaper properties are arranged at the top. are sorted (step S6). For example, when there are three change conditions, the system control unit arranges the property satisfying all conditions at the top, the property satisfying two conditions next, and finally the property satisfying one condition. In addition, the system control unit can also place properties with a high degree of conformity at a higher rank for each condition. For example, in the case of the condition of "wide", the system control unit can place properties with a large (wide) difference from the standard specification at the top, and gradually arrange properties with a smaller difference.

If the change condition "cheap" is selected, and if a property whose rent is 10,000 yen lower and a property whose rent is 50,000 yen lower are searched for as specifications, the system control unit determines that the rent is 50,000 yen. The display order in the terminal device T is sorted so that the cheap property is higher than the property 10,000 yen cheaper. The system control unit converts the property information listing page including the property list including the property information sorted in the display order into a new property based on the selection result of the change conditions and the property information indicating the reference property. The search request is sent to the terminal device T that has sent it (step S7). An example of the property information posting page transmitted at this time is shown in FIG. 5(a). By setting the priority order for each of the change conditions, for example, when there are two change conditions, by plotting the property names as the search results on a two-dimensional map, the user can visually see the first condition spread. It is possible to grasp the degree of conformity of the second condition cheapness.

According to the property search process in steps S1 to S7 described above, properties that satisfy the search conditions based on the specifications of the reference property, for example, the specifications of the property in which the user currently resides, and the change conditions are retrieved. and presented. Therefore, the user can view the search results related to desired properties while reducing the troublesomeness and burden of inputting various specifications for specifying a desired new property.

Further, according to steps S1 and S2, the system control unit acquires the change condition selected by the user from change condition candidates (items of conditions and degree of change). Therefore, the system control unit can search and present properties that meet the user's wishes while reducing the user's troublesome operation.

In addition, if the change conditions are the conditions of the property that are desired to be changed from the specifications of the standard property, or the conditions of the property that are not included in the specifications of the standard property. However, the system control unit can search and present properties that meet the user's wishes while reducing the user's troublesome operation.

Further, according to step S3, information such as an address for specifying the property in which the user is currently living is acquired from the terminal device T as property information serving as a reference. Then, based on the information, the specifications of the property in which the person resides are obtained from the property information database 20 . Therefore, the system control unit can acquire the specifications that serve as the reference for the search only by having the user input the minimum information such as the address. If only one of the properties is entered and there are multiple properties with the same name or at the same address, a plurality of properties will be extracted. , a reference property, that is, a specification can be specified.

In step S7, the system control unit performs a process of setting a preference condition according to this embodiment when transmitting a property information posting page, as illustrated in FIG. 5(a). Specifically, the system control unit transmits to the portable terminal T, as part of the condition setting page, the data of the condition change button 51 that is operated when instructing whether or not to search for a property.

Here, the "special condition" is information for the user to set the degree of realization step by step, such as an essential condition, a desirable condition, and an unnecessary condition, as the specification of the new property. If no particular condition is set, there may be cases where there are few properties that satisfy the user's wishes in the property list of the search results, there are cases where there are no corresponding properties, and there are also cases where the number of searched properties is too large. As an obsession condition, a condition that the user wishes to "definitely obtain" is referred to as an "essential condition". This essential condition can be used when searching for properties again. In addition, a condition that the user desires to "obtain if possible" is referred to as a "desired condition" although it is not essential. This desired condition is used to control the presentation mode when presenting the property information to the user. Furthermore, as a particular condition, a condition that the user wishes not to "obtain" is referred to as an "unnecessary condition". In principle, this unnecessary condition is handled by not extracting properties with unnecessary conditions at the time of re-searching. Properties having the corresponding specifications can be grouped at the lowest display order. Regarding the display order, properties that meet the "essential conditions" are displayed in the highest group, properties that meet the "desired conditions" are displayed in the middle group, and finally properties that meet the "unnecessary conditions" are displayed in the lowest group. Can be displayed in groups. Regarding the relationship between the "essential conditions" and the specifications of the standard property, the system control unit performs the processing of "remain as essential" if the conditions included in this specification are set, and sets the conditions that are not included in this specification. If it is, the process of "newly added as mandatory" is performed. Similarly, with respect to the "requested conditions", the former is processed to "reserve as many conditions as possible", and the latter is processed to "reserve as many new conditions as possible". Similarly, for the "unnecessary condition", the former case is "remove the condition", and the latter case is "not included in the condition".

As illustrated in FIG. 5A, the terminal device T that has received the property information posting page displays the property information posting page including the received property list on the display unit of the terminal device T together with the condition change button 51. do. When the user wants to search for a new property using the particular conditions, the user operates the condition change button 51 illustrated in FIG. 5(a). As a result, the terminal device T transmits to the information providing server SV a request that the user wants to search for a new property using the particular condition.

On the other hand, the system control unit that has transmitted the property information posting page including the property list in step S7 monitors transmission from the terminal device T of a search request for a new property using the particular condition (step S8). In the monitoring of step S8, for example, if a search request for a new property is not transmitted within a preset time (step S8: NO), the system control unit proceeds to step S14, which will be described later. In the monitoring of step S8, if a search request for a new property using the particular condition is transmitted (step S8: YES), the system control unit searches the particular condition candidate database 30. FIG.

If a search request for a new property using the particular condition is transmitted (step S8: YES), the system control unit stores the data of the particular condition setting screen including the retrieved candidate for the particular condition on the condition setting page. It transmits to the terminal device T as a part (step S9). The preference condition setting screen is, for example, the setting screen shown in FIG. On this setting screen, it is possible to select, for each of the candidates for the discerning condition, to make it an essential condition, to make it a desired condition, or to "do not set" it as any condition. It contains a candidate display 44 that has been created.

In the candidate display 44, a condition corresponding to the current status of the property related to the user who uses the terminal device T that has transmitted the search request for the new property may be set in advance as an essential condition. In the candidate display 44, desired conditions may be divided into a plurality of stages. When the desired conditions are divided into a plurality of stages, the system control section can use the selection results for sorting the display order on the terminal device T. FIG. In the candidate display 44, positive conditions such as "corner room" and "facing south" may be set in advance as essential conditions. Furthermore, in the candidate display 44, based on statistical survey results, conditions selected in the past by about 90% of the users are preset as essential conditions, and for example, conditions selected in the past by about 70% of the users are desired conditions. For example, a condition selected in the past by approximately 50% of the users may be preset as a "not set" condition. The degree of this ratio can be increased or decreased as appropriate. For example, conditions selected by 70% of users are essential conditions, conditions selected by 50% of users are desired conditions, conditions selected by 20% of users are unnecessary conditions, You can also make settings like

The terminal device T that receives the data of the setting screen including the candidate display 44 displays the setting screen including the candidate display 44 on the display section of the terminal device T. FIG. For each candidate in the candidate display 44, the user selects, for example, a drag operation to select either an essential condition, a desired condition, or "do not set". Candidates selected as “not set” include cases where candidates that have been selected as essential conditions or desired conditions are excluded from those selections. Candidates excluded from the essential conditions or desired conditions are the conditions of properties that the user no longer desires (that is, wants to let go). The terminal device T on which the setting screen including the candidate display 44 is displayed transmits the selection result of the preference condition to the information providing server SV. The system control unit acquires the transmitted selection result of the preference condition (step S10).

Next, when the system control unit receives the selection result of the particular condition, the condition selected as the essential condition among the particular condition, the reference property information acquired in step S1, and the property information used in the property search in step S4. The property information database 20 is searched based on the changed conditions.

Specifically, the system control unit newly generates a search condition that satisfies the selection result of the modification condition and the essential condition for the reference property condition (step S11). The system control unit searches the property information database 20 using the newly generated search conditions (step S12). The system control unit acquires, from the property information database 20, property information indicating properties that satisfy the change conditions and essential conditions with respect to the reference property conditions as the search result of step S12. Next, the system control unit displays the properties indicated by the obtained property information in the display order on the terminal device T so that the property with the greater number of requested conditions satisfied in the property search in step S12 is displayed at a higher rank. are sorted to generate a new property list (step S13). This makes it possible to present the property information in a presentation mode corresponding to the desired conditions. The property list generated as a result of step S13 is, for example, the property list shown in FIG. 5(c).

In addition, as illustrated in FIG. 5(c), the system control unit selects, among the desired conditions selected by the user as desired conditions, conditions that were not satisfied by the property searched in step S12. is displayed for each property with, for example, an erasure line, a search result column 45 is generated and included in the property list. Further, in the search result column 45, the number of conditions satisfied by the properties searched by the property search in step S12 among the specific conditions selected by the user as the desired conditions is displayed in a recognizable manner for each property.

For example, in the candidate display 44 illustrated in FIG. 5B, there is one candidate selected as the essential condition, and a total of 13 candidates selected as the desired condition. Assume that there are 7 desired conditions that are not satisfied in the properties that have been selected. In this case, in the search result column 45 shown in FIG. 5C, "7/14 pieces" is displayed as the "condition" column. The numerator of this fraction means the sum of the number of required conditions and the number of desired conditions that are satisfied in the property displayed as the property list. In the case of the above example, the number of essential conditions satisfied in the property displayed as the property list is one, and the number of desired conditions is six. Also, the denominator of the fraction means the sum of the number of essential conditions and the number of desired conditions selected in the candidate display 44 illustrated in FIG. 5(b). In the example above, the sum is "14". Further, in the particular condition search result column 45 shown in FIG. 5(c), the desired conditions that were not satisfied in the properties searched by the property search in step S12 are "separate bath/toilet", "independent washbasin", "pet 7 items are displayed, namely, consultation possible, free internet, remodeling, renovation, and special rent (specified excellent rental housing). These seven requirements are displayed with an elimination line. By displaying the search result column 45, property information is presented in a presentation mode corresponding to the desired conditions.

According to the property search in steps S9 to S13 described above, a plurality of conditions for properties may be set as essential conditions for property search, or as desired conditions for sorting property information, or as any of the conditions. After selecting whether to use or not, a property is searched based on the selection result, and the property information is presented. Therefore, the system control unit can present property information through property search that expands options for the user who wishes to present property information.

In addition, in the display of the property list including the result of the property search, the property information of the property that satisfies the selected desired condition is preferentially displayed. Therefore, the system control unit can preferentially present a property that meets the user's request.

Furthermore, the more properties that satisfy the selected desired condition, the higher the list is displayed. Therefore, the system control unit can preferentially present properties that match the user's desires in an easily recognizable manner.

Furthermore, information for identifying whether or not the properties included in the property list and presented satisfy the desired condition is included in the property list and presented. Therefore, the user can easily recognize which property satisfies any of the selected desired conditions.

In addition, unsatisfied desired conditions and information enabling recognition of the number of satisfied desired conditions are included in the property list and presented. Therefore, the user can specifically recognize which of the selected desired conditions is satisfied.

After the new property list is generated in step S13, the system control unit proceeds to step S7. In step S7, the system control unit transmits the property information posting page including the property list generated in step S13 to the terminal device T used by the user who has transmitted the new property search request using the particular condition. . After that, the system control unit repeats the processes after step S8 described above.

On the other hand, in the monitoring of step S8, if no search request for a new property has been sent (step S8: NO), the system control unit selects the It monitors the transmission of information indicating the properties that have been purchased (step S14). The property selected in this case is the property desired by the user. In the monitoring of step S14, for example, if information indicating the selected property is not transmitted within a preset time (step S14: NO), the system control unit proceeds to step S16, which will be described later.

The property list includes property information that is currently recruiting residents and that is scheduled to be recruited, but the property list may include property information that is not scheduled to be recruited. When the user selects (i.e. reserves) information on a property that is not scheduled to be solicited, the system control unit adds the user information and reservation information to the relevant property, and sends an e-mail to the user as soon as the solicitation schedule is determined. It is possible to send an examination request guide by, for example. With such a function, the user can wait for the availability of the property that he likes.

On the other hand, in the monitoring of step S14, if information indicating the selected property has been transmitted (step S14: YES), the system control unit performs preset related processing such as contract processing for the property (step S15).

After that, the system control unit determines whether or not to end the property search process of the present embodiment, for example, because the user has performed a termination operation on the terminal device T (step S16). If it is determined in step S16 that the property search process of the present embodiment is not terminated (step S16: NO), the system control unit returns to step S1 and repeats the above-described processes. On the other hand, if the property search process of this embodiment is to be ended in the determination of step S16 (step S16: YES), the system control unit ends the property search process of this embodiment as it is.

As a modified example of the present embodiment, a property search may be performed using particular conditions first without going through steps S1 to S7 shown in FIG. In this case, the user can search for a property using more specific preference conditions.

In addition, instead of controlling the display order of the properties using the desired conditions according to the present embodiment, the system control unit controls the display (for example, characters, images) on the terminal device T as the number of properties that satisfy the desired conditions increases. The presentation mode may be controlled so as to increase the size, make the color of the characters stand out, or increase the number of items of property information to be displayed. Even in this case, the system control unit can preferentially present properties that are more in line with the user's intentions and are easier to recognize.

Furthermore, the system control unit obtains reference property information (see step S3 in FIG. 3) before presenting the change conditions (see step S1 in FIG. 3) and acquiring the selection result (step S2 in FIG. 3). good too. That is, steps S3, S1, and S2 can be processed in order. In this case, the system control unit presents the specifications of the reference property to the user, and presents a selection screen such as which conditions should be handled. An effect that the conditions can be easily grasped can be obtained. In order to support the setting of conditions to be changed or unnecessary, the system control unit provides a list of conditions and how to change them. Prepare your options. In order to support the setting of insufficient conditions, that is, new conditions to be obtained, the system control unit searches the property information database 20 registered in the database DB for conditions that are not included in the specifications of the reference property, such as "auto lock". , “manager resident”, “party room”, “pool”, etc. are extracted and presented to the terminal device T. FIG.

Furthermore, a program corresponding to the flowchart shown in FIG. 3 is recorded on a recording medium such as an optical disk or hard disk, or obtained from a network such as the Internet and recorded, and read out by a general-purpose microcomputer. It is also possible to cause the microcomputer to function as the system control unit of this embodiment without accessing the network during the processing.
