Specifically, this property site selection screen is used to select a real estate agent's website to be searched, and in addition to a link for accessing each real estate agent's website, It contains information such as the number of properties handled and whether or not there are rental properties or properties for sale. The user can select the website of the real estate agent to be searched by selecting a check box or the like provided for each website of the real estate agent. In addition, for the convenience of the user who has a predetermined region to be searched for, for example, the property site selection screen is not limited to a region, but for the purpose of searching a real estate agent's website nationwide Those classified into predetermined categories are desirable, such as a national version or a regional version in which a real estate agent's website for each region is searched. In addition, this property site selection screen not only presents the national version and the real estate agent website for each region as a search target, but also, for example, the real estate agent website that handles real estate property information for students Or a screen summarizing a website of a real estate agent handling real estate property information for which pet breeding is permitted, and the screen for each category is tab 51. , 52, 53, etc., so that switching display is possible. In the real estate property information search system, even if the property site selection screen is configured so that the screens for each category can be switched and displayed by the plurality of tabs 51, 52, 53, the selection items on each screen are exclusive. All items selected between different screens can be reflected as search targets.

  In the user terminal 10, in step S4 in FIG. 3, the website of the desired real estate agent to be searched is selected by the user via such a property site selection screen, and a transition button 54 to the next screen is selected. Is selected. Accordingly, a search type / condition designation screen as shown in FIG. 5 is displayed on the display unit 17 of the user terminal 10, for example.

  Specifically, this search type / condition designation screen is used to input and specify a search type and a search condition. The types of search include identification of whether the search is for a rental property or for sale, and whether the search is from a railway line or station name where the real estate property is located or from a location. The search type / condition specifying screen is provided with a search type specifying unit 61 for inputting and specifying these search types. This search type designation section 61 is a search from a radio button for alternatively selecting a search for a rental property or a search for a sale property, or a search from a railway line or a station name where a real estate property exists. A radio button or the like for selectively selecting whether the search is from a location or a location, and a combo box that displays a railway box or station name or location as a character string or a selectable list Etc. are provided.

  In the case of a method of selecting a railway line or a station name from a combo box, the search server device 20 obtains information such as a route name, a station name, and a prefecture through which the route passes, as shown in FIG. 6, for example. In the case of a method in which a defined route station table is stored in advance and the location is selected from a combo box, information such as a prefecture, a city, a town name, an address, and a postal code is shown in FIG. Is stored in advance, and a list of combo boxes is created based on these tables. Further, instead of such a table, the search server device 20 may create a list by referring to a setting file described in so-called XML (eXtensible Markup Language) in which similar information is described.

  On the other hand, the search conditions include apartment type and apartment type, rent and price, floor plan, area, time required for walking from the nearest station, building age, two floors and more, and other various conditions such as parking lots. In the search type / condition specifying screen, a search condition specifying unit 62 for inputting and specifying these search conditions is provided. The search condition designating unit 62 includes a check box for selecting a property type, a combo box for displaying upper and lower limits of rent and price as a selectable list, a check box for selecting a floor plan, and an upper limit of area. And a combo box that displays the lower limit as a selectable list, a radio button for selecting the required time by walking from the nearest station, a check box for selecting various other conditions, etc. A radio button or the like is provided to selectively select the display order of the search result list. In the real estate property information search system, a search type specification screen for inputting and specifying a search type and a condition specifying screen for inputting and specifying a search condition may be configured separately.

  In the user terminal 10, in step S5 in FIG. 3, various search conditions including a desired search type are input and specified via such a search type / condition specifying screen, and the search button 63 is selected. In response to this, in step S6, the user terminal 10 accesses the search server device 20 and requests a search for real estate property information based on the input search conditions. In response to receiving a request for searching for real estate property information in step S7, the search server device 20 analyzes various received search conditions in step S8, and in step S9, via the property site selection screen. Analyzes information on the website of the selected real estate agent. Then, in step S10, the search server device 20 creates an HTTP (HyperText Transfer Protocol) request for acquiring information on the websites of all selected real estate agents in association with each website, and in step S11. The search for the real estate property information is requested by transmitting the created HTTP request to the web server device 30 that provides the websites of all the selected real estate agents.

  In response to receiving a request for searching for real estate property information in step S12, the web server device 30 refers to its own database and searches for real estate property information that matches the search conditions in step S13. Then, in step S14, the web server device 30 creates a search result web page indicating the search result. In step S15, the web server device 30 sends the created search result web page to the search server device 20 as a response to the search server device 20. To send.

  In response to receiving the search result web page in step S16, the search server device 20 extracts real estate property information from the received search result web page in step S17. In step S18, the search server device 20 extracts the extracted real estate property information. Store in the database. Then, in step S19, the search server device 20 determines whether the real estate property information from all the selected real estate agent websites has been acquired and stored in the database. Here, if the search server device 20 determines that the real estate property information from all the selected real estate agent websites has not been acquired and stored in the database, the processing from step S16 is repeated. If it is determined that the real estate property information from the websites of all the selected real estate agents is acquired and stored in the database, the real estate property information is extracted from the created database as a list in step S20. Then, the search server device 20 creates a search result web page indicating the search result in step S21, and uses the created search result web page as a response to the user terminal 10 in step S22. Send to.

  In response to receiving the search result web page in step S23, the user terminal 10 displays a search result screen as shown in FIG. 8 on the display unit 17 in step S24, for example. Specifically, this search result screen displays real estate property information searched on each real estate agent's website as a list, and the list is a list of information indicating simplified contents related to the searched real estate properties. In addition, it includes a link for accessing a web page on which detailed contents regarding the real estate property are posted, a link for accessing a website that is an information source of the real estate property, and the like. In addition, when there are many search results, this search result screen is divided into a plurality of pages and is provided with a transition button 71 for transitioning to another page. Further, the search result screen is also provided with a download button 72 for downloading the search result as, for example, a CSV (Comma Separated Values) format file.

  In the real estate property information retrieval system, the screen as shown in FIGS. 4, 5, and 8 is generally displayed on the display unit 17 of the user terminal 10 through such a series of steps. However, real estate property information can be searched from a plurality of real estate agent websites.

  Now, the details of the processing in such a real estate property information search system will be described below.

  In the real estate property information search system, an HTTP request and an HTTP response are exchanged between the user terminal 10 and the search server device 20, and between the search server device 20 and the web server device 30, respectively. Real estate property information search from multiple real estate agent websites. Specifically, in the real estate property information search system, the real estate property information is searched from a plurality of real estate agent websites through a series of steps shown in FIGS. In the following, for convenience of explanation, it is assumed that a web page written in HTML (HyperText Markup Language) is handled.

  First, in the real estate property information search system, as shown in FIG. 9, in step S31, a predetermined operation for requesting the property site selection screen as shown in FIG. Is done by. Specifically, in the user terminal 10, a URL (Uniform Resource Locator) address is operated by the user operating the keyboard while executing the application program as a web browser and displaying the screen on the display unit 17. The property site selection screen is requested to be entered by inputting or entering a click on a predetermined link or a so-called submit button by operating a mouse or the like. In response to this, the user terminal 10 creates an HTTP request by an application program as a web browser and transmits it to the search server device 20 in step S32. At this time, the web browser uses a so-called get method or post method as a communication method with the search server device 20. As the communication method, it is desirable to use a post method when the amount of data is large or when authentication is required.

  Subsequently, in response to receiving an HTTP request in step S33, the search server device 20 creates a web page in HTML format indicating a property site selection screen in step S34, and in step S35, the HTML data is generated. It transmits to the user terminal 10 as an HTTP response. As shown in FIG. 11, for example, the search server device 20 includes a website identification name (sitename), a website official name (sitename_ja), the category (category) described above, and the number of listed articles (bukken_num). Various properties related to each real estate agent's website, such as rental property (cariru) that defines the presence or absence of rental properties, sale property (uri) that defines the presence or absence of sales properties, website URL (home_url), and explanatory comments A site information table in which information is defined is stored in advance, and a property site selection screen is created based on the site information table. In addition, instead of such a site information table, the search server device 20 directly describes similar information in the code of a program such as a so-called Java (registered trademark), or similar information is stored in XML or CSV format. The property site selection screen may be created by referring to the described setting file. In step S36, the user terminal 10 receives the HTTP response by the application program as a web browser, and in step S37, displays the property site selection screen as shown in FIG. .

  Subsequently, in the user terminal 10, in step S38, when the desired real estate agent websites (1,..., N) to be searched are selected via the property site selection screen, In step S39, the user performs a predetermined operation for requesting the search type / condition designation screen as shown in FIG. Specifically, in the user terminal 10, the user operates the keyboard on the web browser to input a URL address, or operates the mouse or the like, similar to the request operation on the property site selection screen described above. By clicking a predetermined link or submit button, a request operation on the search type / condition designation screen is performed. In response, the user terminal 10 creates an HTTP request by an application program as a web browser and transmits it to the search server device 20 in step S40. Also at this time, as described above, the web browser uses the get method or the post method as the communication method with the search server device 20.

  Subsequently, in response to receiving the HTTP request in step S41, the search server device 20 performs query parameter acquisition processing from the received HTTP request in step S42. This query parameter acquisition process is shown in FIG.

  That is, as shown in the figure, when the search server device 20 receives an HTTP request in step S41, the search server device 20 obtains a query parameter corresponding to the website of the selected real estate agent from the received HTTP request in step S42a. To do. This query parameter indicates information input by the user via the user terminal 10, and when an HTTP request is transmitted using the get method, the query parameter is indicated by an underlined portion in FIG. As shown in FIG. 13B, when an HTTP request is added using a post method and added to the URI (Uniform Resource Identifier) portion of the request line, Added. For example, as shown in FIG. 14, when “AA Real Estate Website” and “BB Property Website” are selected from a plurality of real estate agent websites displayed on the property site selection screen in a selectable manner. As shown in FIG. 15, the selected information is described as “name value = value value” in the HTML data. When there are a plurality of pieces of information, the information shown in FIGS. 13 (a) and 13 (b) is displayed. As shown, it will be combined with "&". In addition, the real estate agent's website not selected via the property site selection screen is not added to the query parameter. The search server device 20 uses an API (Application Program Interface) provided by Java (registered trademark) or the like for acquiring a query parameter included in an HTTP request without being aware of the difference between the get method and the post method. Query parameters can be obtained.

  When the search server device 20 acquires the query parameter in this way, the character code of the acquired query parameter is converted into an appropriate one in step S42b in FIG. The character code of the query parameter is so-called shift JIS, EUC-JP, etc., and it is converted into the internal character code of the programming language, for example, Unicode in the case of Java (registered trademark) for appropriate processing. There is a need to. Therefore, the search server device 20 performs a conversion process of the character code of the acquired query parameter. At this time, if the search server device 20 knows the character code in advance, the search server device 20 performs a specific conversion process, but may not be specified in advance depending on the web browser. Conversion processing is performed using the automatic determination API. When the search server device 20 receives an HTTP response, the search server device 20 performs the same conversion process on the character code of the HTML data. In step S42c, the search server device 20 stores the acquired query parameters (1,..., N) in a variable [sites].

  Subsequently, when the search server device 20 performs such query parameter acquisition processing, in step S43 in FIG. 9, the search server device 20 creates an HTML-format web page indicating the search type / condition designation screen. In step S44, the search server device 20 The HTML data is transmitted as an HTTP response to the user terminal 10. In step S45, the user terminal 10 receives the HTTP response by the application program as a web browser. In step S46, the search type / condition designation screen as shown in FIG. indicate.

  Subsequently, in the user terminal 10, in step S47, the search type is input specified via the search type / condition specifying screen, and when the search condition is input specified in step S48, in step S49. The user performs a predetermined operation for requesting a search for real estate property information that matches these search types and search conditions. Specifically, in the user terminal 10, the user operates the keyboard on the web browser and inputs a URL address in the same manner as the request operation on the property site selection screen and the search type / condition designation screen described above. A search request operation is performed by operating a mouse or the like and clicking a predetermined link or submit button. In response to this, the user terminal 10 creates an HTTP request by the application program as a web browser and transmits it to the search server device 20 in step S50. Also at this time, as described above, the web browser uses the get method or the post method as the communication method with the search server device 20.

  Subsequently, in response to receiving an HTTP request in step S51, the search server device 20 performs query parameter acquisition processing from the received HTTP request in step S52. This query parameter acquisition process is shown in FIG.

  That is, as shown in the figure, when the search server device 20 receives an HTTP request in step S51, in step S52a, the search server device 20 obtains a query parameter corresponding to the specified search type and search condition from the received HTTP request. get. The message format of the HTTP request including the query parameter is the same as that described above with reference to FIG. 13, and the search server device 20 acquires the query parameter using a predetermined API.

  Subsequently, in step S52b, the search server device 20 converts the acquired character code of the query parameter into an appropriate one in the same manner as described above. In step S52c, the search server device 20 stores the query parameters (1,..., M) for the acquired search type in a variable [kinds], and in step S52d, the search server device 20 The query parameters (1,..., L) are stored in a variable [bukken_options]. Further, in step S52e, the query parameters (1,. Store in variable [sort_options].

  Subsequently, when such a query parameter acquisition process is performed, the search server device 20 creates a temporary table for storing real estate property information data acquired later from the web server device 30 in step S53 in FIG. . This temporary table is created in order to secure a space for storing real estate property information data in advance, and of course the values are not stored in the temporary table at this stage. is there. And the search server apparatus 20 starts the acquisition process of the real estate property information data in the website of a corresponding real estate agent with reference to the variable [sites] mentioned above in Step S54. The startup process of the real estate property information data acquisition process is shown in FIG.

  That is, as shown in the figure, the search server device 20 extracts one value from the variable [sites] (1,..., N) in step S54a, and the extracted value is the real estate agent in step S54b. It is determined whether or not “aa” indicating A's website. Here, if the retrieval server device 20 determines that the extracted value is “aa”, in step S54c, the retrieval server device 20 starts acquisition processing of real estate property information data on the website of the real estate agent A. If the search server device 20 determines that the extracted value is not “aa”, the search server device 20 determines whether or not the extracted value is “bb” indicating the website of the real estate agent B in step S54d. judge. When it is determined that the extracted value is “bb”, the search server device 20 starts acquisition processing of real estate property information data on the website of the real estate agent B in step S54e. Further, when the search server device 20 determines that the extracted value is not “bb”, in step S54f, the search server device 20 determines whether or not the extracted value is “cc” indicating the website of the real estate agent C. judge. When it is determined that the extracted value is “cc”, the search server device 20 starts real estate property information data acquisition processing on the website of the real estate agent C in step S54g. The search server device 20 repeats the start determination of the real estate property information data acquisition process as many times as the number of websites to be searched. At this time, the search server device 20 starts the process by directly describing the extracted value and the corresponding process name in the program code, as shown in the example of Java (registered trademark) in FIG. Or a process name table as shown in FIG. 19 in which a value (parameter_value) and a process name (sub_name) are defined, or an XML or CSV format as shown in FIG. 20 in which a value and a process name are described. The setting file is stored in advance, and the processing is started by referring to them. Then, in step S54h, the search server device 20 determines whether all (N) values have been extracted from the variable [sites]. If all values have been extracted, the real estate in step S55 in FIG. Shift to acquisition processing of property information data.

  This acquisition process of real estate property information data is performed in parallel for all websites selected by the user. Specifically, real estate property information data acquisition processing is performed as shown in FIGS.

  That is, as shown in FIG. 21, in step S55a, the search server device 20 refers to the variable [kinds] and the variable [bukken_options], acquires a value from the pre-stored query parameter table, and creates a parameter. . Here, the query parameter table defines query parameters used by the search server device 20 and corresponding query parameters of each website. For example, as shown in FIG. 23, a website identification name (site), Necessary number of times (is_required) that defines whether it is an indispensable parameter or how many requests are required, a unique parameter (is_unique) that defines whether it is a unique parameter of the website, rental property The parameter name (mname) used by the search server device 20 such as the identification of the property for sale and the type of property, the parameter value (mvalue) used by the search server device 20, the corresponding parameter name (sname) of the website, the website The corresponding par Meter value (svalue), and consists of information such as comments for explanation. For example, when the query parameter corresponding to “Property Type: Apartment” as the search condition used by the search server device 20 is “bukkenType = apart”, the website of the real estate agent A whose identification name is “aa” The corresponding parameter is “APARTMENT = 1” in which site, mname, and mvalue match. The search server device 20 combines parameters obtained from such a query parameter table with “&” such as “AA = 1 & BB = 1 & CC = 1 &. Note that the search server device 20 may create a parameter by referring to a setting file described in XML or CSV format in which similar information is described instead of such a query parameter table.

  Subsequently, in step S55b in FIG. 21, when the query parameter includes a space, a 2-byte character or the like in the query parameter, the search server device 20 encodes this into a “% XX” format using a predetermined API. In step S55c, the URL of the request destination and the query parameter are set as an HTTP request by referring to the site information table as shown in FIG. 11 and acquiring the URL of the request destination. In step S55d, this HTTP request is transmitted to the corresponding web server device 30.

  When receiving the HTTP request in step S55e, the web server device 30 refers to its own database based on the received HTTP request and searches for real estate property information that matches the search condition in step S55f. Then, in step S55g, the web server device 30 creates an HTML-format web page indicating the search result screen, and in step S55h, transmits the HTML data to the search server device 20 as an HTTP response. Then, the search server device 20 receives the HTTP response in step S55i, converts the character code of the received HTML data into an appropriate one in step S55j in the same manner as described above, and in step S55k Analyze HTML data. Here, the HTML data to be analyzed includes content including a character string and other elements between the start tag described as <element name> and the end tag described as </ element name>. The described unit is configured as an element, and a plurality of attributes can be arbitrarily given to each element by setting <element name attribute name = “attribute value”>. The search server device 20 analyzes the constituent elements of the HTML data using an API provided by Java (registered trademark) for analyzing HTML data.

  Subsequently, as shown in FIG. 22, the search server device 20 determines whether or not there is a character string such as “There was no property that matched the search condition” as a result of the analysis of the HTML data in step S55l. Thus, it is determined whether or not there is a search result on the website. Here, when it is determined that there is no search result on the website, the search server device 20 determines that there is a search result on the website while ending a series of real estate property information data acquisition processing. In that case, in step S55m, real estate property information data is extracted from the HTML data. Here, although real estate property information data is generally often described in an element <TABLE>, since many HTML data includes a plurality of elements <TABLE>, any element is included. It is necessary to specify whether the real estate property information data is stored in <TABLE>. Therefore, the search server device 20 extracts real estate property information data as follows, for example. That is, when there is HTML data as shown in FIG. 24 as the first extraction method, the search server device 20 includes, for example, the element <TR> appearing after the second element in the element <TABLE> appearing sixth. The data can be extracted by specifying the position of the element, such as the character string or attribute. In addition, as a second extraction method, for example, the search server device 20 appears in the second and subsequent elements <TABLE> including character strings such as “rent” and “building age” in the element <TR> that appears first. It is possible to specify an element including a specific character string such as a character string or attribute in the element <TR> and extract data in the element. The element <TR> in the figure represents one row in the element <TABLE>, the element <TD> represents one cell in the element <TR>, and the element <a href=“”> is a link. Represents the destination. In this way, the search server device 20 can extract real estate property information data. In addition, when there is a next page in the search result, the search server device 20 may acquire information necessary for transitioning to the next page because the HTML data may be included in the HTML data. Is performed at any stage before and after the extraction of the real estate property information data. As this information, for example, information in an element whose type attribute of a so-called INPUT tag is “hidden” is unknown and needs to be analyzed for each search.

  Subsequently, when the search server device 20 extracts the real estate property information data in this way, in step S55n in FIG. 22, it is determined whether or not all the real estate property information data has been extracted from the HTML data. When all the real estate property information data is extracted, in step S55o, the extracted real estate property information data is converted into an appropriate data format. That is, since the real estate property information data extracted from the HTML data is a character string type, the search server device 20 converts the data format in accordance with the format of each column constituting the temporary table described above as the storage destination. . At this time, the search server device 20 converts the display format of the real estate property information data different for each website into a unified display format. Specifically, when the data corresponding to the rent is a character string type “50,000 yen”, the search server device 20 changes the character string type “50,000 yen” to the character string type “50000”. The character string type “50000” is converted to the numeric type “50000”. Similarly, if the data corresponding to the building age is “02/10” of the character string type representing October 2002, the search server device 20 changes the character string type “02/10” to the character. The character string type “2002/10/01” is converted to the date type “2002/10/01”.

  When the search server device 20 converts the real estate property information data into an appropriate data format in this way, in step S55p, the real estate property information data is stored in a temporary table, for example, as shown in FIG. Name (siteName), link to access an existing web page with detailed information about each real estate property (detail), route name of nearest station (rosen), station name (station) of nearest station, address (address), Time required by walking from the nearest station (toho), time required by bus from the nearest station (bus), rent and price (price), management fee (kanrihi), deposit (rekin), key money (rekin), deposit (hosyokin) ), Cancellation fee (kaiyakuki) ), A temporary property data table composed of various real estate property information data such as shikibiki, layout, layout, area, type, structure, and building age (chikunen) create. Then, in step S55q, the search server device 20 determines whether or not the next page exists in the search result. For example, the search server device 20 determines whether or not the HTML data acquired from the website includes a character string “next” for transitioning to the next page, a transition button, and the like. Determine whether the page exists. Of course, this determination method differs depending on the representation method of the HTML data acquired from the website. When the search server device 20 determines that the next page exists in the search result, the search server device 20 repeats the processing from step S55a in FIG. 21, while when it determines that the next page does not exist in the search result. Then, a series of real estate property information data acquisition processing is terminated.

  The search server device 20 performs such acquisition processing of real estate property information data in parallel for all websites selected by the user, and waits for the processing for all these websites to end. Then, the process proceeds to step S56 in FIG. In step S56, the search server device 20 refers to the variable [sort_options] described above, and displays a list of search results input by the user by using, for example, a SELECT command or an ORDERBY command in SQL (Structured Query Language). According to the order, real estate property information data is extracted from the temporary table. Then, in step S57, the search server device 20 creates an HTML web page indicating the search result screen, and in step S58, transmits the HTML data as an HTTP response to the user terminal 10. In response to this, the user terminal 10 receives the HTTP response by the application program as a web browser in step S59, and in step S60, the search result screen as shown in FIG. Display, and the series of processing ends.

  In the real estate property information search system, through such a series of steps, between the user terminal 10 and the search server device 20, and between the search server device 20 and the web server device 30, respectively. It is possible to search for real estate property information from the websites of a plurality of real estate agents by exchanging HTTP requests and HTTP responses.

  As described above, in the real estate property information search system shown as the first embodiment of the present invention, a plurality of existing websites respectively provided by a plurality of real estate agents via the search server device 20 are stored. By accessing the web server device 30 and causing the plurality of web server devices 30 to perform a search in accordance with the search conditions designated and input via the user terminal 10, a plurality of existing web sites The real estate property information posted on the site can be searched, and the desired information can be searched from these real estate property information very easily and efficiently according to the user's one-time search condition specification as a list Can be provided.

  Here, in the real estate property information search system, since it is realized as a search engine type service by the search server device 20, there is no need to install a dedicated application program in the user terminal 10, and function upgrades, etc. In this case, since only the maintenance of the search server device 20 needs to be performed, there is no burden on the user. As described above, the real estate property information search system can realize a search that is not confined to a real estate agent, can compare real estate properties with the same conditions handled by different real estate agents, and is extremely convenient for the user. It is expensive.

  Next, a real estate property information search system shown as a second embodiment will be described. This real estate property information retrieval system executes real-time property information posted on a website provided by a plurality of real estate agents without using a search server device by executing a predetermined application program by a user terminal. This is a meta search for. Therefore, in the description of the second embodiment, the same components as those in the description of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  Specifically, as shown in FIG. 26, the real estate property information search system includes a user terminal 10 possessed by a user and a plurality of web server devices 30 possessed by a plurality of real estate agents, and these users. Terminal 10 and web server 30 are configured to be connected via a predetermined network NT.

  The user terminal 10 is configured as shown in FIG. 2, and a predetermined real estate property information search program is installed. This real estate property information search program is distributed in a form recorded on a recording medium such as a CD-ROM or downloaded from a providing site via a predetermined network such as the Internet. The user terminal 10 accesses the plurality of web server devices 30 via the network NT by executing such a real estate property information search program under the control of the CPU 11, and satisfies the search conditions. A search request for matching real estate property information is made. Then, under the control of the CPU 11, the user terminal 10 creates a final search result based on the individual search results transmitted from the web server device 30, and displays this information on the display unit 17. indicate.

  In such a real estate property information search system, the real estate property information is searched through a series of steps as shown in FIG.

  First, in the real estate property information search system, as shown in the figure, as a predetermined real estate property information search program is executed by the user terminal 10, the real estate property information search screen is displayed on the user terminal. 10 on the display unit 17. As a result, the property site selection screen with the contents shown in FIG. 4 is displayed on the display unit 17 of the user terminal 10. The property site selection screen shown in the figure is shown as a web browser screen, but the user terminal 10 is not a web browser, but a predetermined property site selection as an execution screen for a real estate property information search program. Display the screen.

  In the user terminal 10, when the property site selection screen is displayed on the display unit 17, in step S101 in FIG. 27, the website of a desired real estate agent to be searched by the user is displayed via the property site selection screen. The transition button 54 to the next screen is selected. As a result, a search type / condition designation screen with the contents shown in FIG. 5 is displayed on the display unit 17 of the user terminal 10. Although the search type / condition designation screen shown in FIG. 5 is shown as a web browser screen, the user terminal 10 is not a web browser, but a predetermined search as an execution screen for a real estate property information search program. Display the type / condition specification screen.

  Note that the user terminal 10 is provided by a relational database that can be incorporated into a program such as so-called HSQLDB, a route station table as shown in FIG. 6 or a location table as shown in FIG. A list of combo boxes can be created based on a table having the same contents as. This HSQLDB is effective in creating a real estate property information search program because its size is small and it can be easily installed.

  In the user terminal 10, in step S102 in FIG. 27, when various search conditions including a desired search type are input and specified through such a search type / condition specifying screen, and the search button 63 is selected. In step S103, various input search conditions are analyzed, and in step S104, information on the website of the real estate agent selected via the property site selection screen is analyzed. In step S105, the user terminal 10 creates an HTTP request for acquiring information on the websites of all the selected real estate agents for each website, and the user terminal 10 selected in step S106. A search for real estate property information is requested by transmitting the created HTTP request to the web server device 30 that provides all real estate agent websites.

  In response to receiving a request for searching for real estate property information in step S107, the web server device 30 refers to its own database and searches for real estate property information that matches the search conditions in step S108. In step S109, the web server device 30 creates a search result web page indicating the search result. In step S110, the web server device 30 uses the created search result web page as a response to the user terminal 10. Send to.

  In response to receiving the search result web page in step S111, the user terminal 10 extracts the real estate property information from the received search result web page in step S112, and in step S113, the extracted real estate property information. Is stored in the database. In step S114, the user terminal 10 determines whether the real estate property information from all selected real estate agent websites has been acquired and stored in the database. Here, if the user terminal 10 determines that the real estate property information from all the selected real estate agent websites is acquired and not stored in the database, the processing from step S111 is repeated. On the other hand, if it is determined that the real estate property information from all the selected real estate agent websites has been acquired and stored in the database, the real estate property information is extracted from the created database as a list in step S115. . In step S116, the user terminal 10 creates a search result screen showing the search result as shown in FIG. 8 and displays it on the display unit 17. Although the search result screen shown in the figure is shown as a web browser screen, the user terminal 10 does not use a web browser but a predetermined search result screen as an execution screen for the real estate property information search program. indicate.

  In the real estate property information search system, it is generally possible to search for real estate property information from a plurality of real estate agent websites through a series of such steps.

  Now, the details of the processing in such a real estate property information search system will be described below.

  In the real estate property information search system, by transferring HTTP requests and HTTP responses between the user terminal 10 and the web server device 30, respectively, real estate property information from a plurality of real estate agent websites Realize the search. Specifically, in the real estate property information search system, the real estate property information is searched from the websites of a plurality of real estate agents through a series of steps shown in FIGS. In the following, for convenience of explanation, it is assumed that a web page described in HTML is handled.

  First, in the real estate property information search system, as shown in FIG. 28, by executing the real estate property information search program by the user terminal 10 in step S121, the property site selection as shown in FIG. The screen is displayed on the display unit 17 of the user terminal 10. The user terminal 10 creates a property site selection screen based on a table having the same contents as the site information table as shown in FIG.

  Subsequently, in the user terminal 10, in step S122, when the desired real estate agent websites (1,..., N) to be searched are selected via the property site selection screen, In step S123, an acquisition process of information on the website of the selected real estate agent is performed. This acquisition process is shown in FIG. That is, as shown in the figure, the user terminal 10 obtains information on the website of the selected real estate agent, that is, information input by the user via the user terminal 10 in step S123a. . In step S123b, the user terminal 10 stores the acquired information (1,..., N) in the variable [sites].

  When the user terminal 10 performs such information acquisition processing, the search type / condition designation screen as shown in FIG. 5 is displayed on the display unit 17 in step S124 in FIG. In the user terminal 10, in step S 125, the search type is input specified via the search type / condition specifying screen, and when the search condition is input specified in step S 126, the input is specified. A process for acquiring information on search types and search conditions is performed. This information acquisition process is shown in FIG.

  That is, as shown in the figure, when the user terminal 10 obtains the information of the search type and the search condition that are designated for input in step S127a, in step S127b, the information (1,. .., M) are stored in the variable [kinds], and in step S127c, information (1,..., L) on the acquired search condition is stored in the variable [buken_options], and further, in step S127d. The information (1,..., K pieces) about the display order of the list of search results is stored in the variable [sort_options].

  When the user terminal 10 performs such information acquisition processing, in step S128 in FIG. 29, the user terminal 10 refers to the variable [sites] described above, and acquires real estate property information data on the corresponding real estate agent website. Start up. The startup process of the real estate property information data acquisition process is the same as the process performed by the search server device 20 shown in FIG. The user terminal 10 reserves an area as a property data storage table for storing the real estate property information data acquired from the web server device 30 in advance, and does not need to create the temporary table described above in the database. . That is, since the user terminal 10 only needs to execute the installed real estate property information search program, a temporary table for each user is provided in response to a search request as in the first embodiment. There is no need to create it. Therefore, the user terminal 10 can reduce the time for processing to create and delete the temporary table. When all (N) values are extracted from the variable [sites], the user terminal 10 proceeds to the real estate property information data acquisition process in step S129 in FIG.

  This acquisition process of real estate property information data is performed in parallel for all websites selected by the user. Specifically, real estate property information data acquisition processing is performed as shown in FIGS. 32 and 33.

  That is, as shown in FIG. 32, the user terminal 10 refers to the variable [kinds] and the variable [bukken_options] in step S <b> 129 a, and uses the query parameter table as shown in FIG. A parameter is created by referring to a setting file described in XML or CSV format in which is described.

  Subsequently, in step S129b, the user terminal 10 URL-encodes the query parameter in a “% XX” format using a predetermined API if the query parameter includes a space, a 2-byte character, or the like. In step S129c, the URL of the request destination is acquired by referring to a table having the same contents as the site information table shown in FIG. The request is set, and in step S129d, the HTTP request is transmitted to the corresponding web server device 30.

  When receiving the HTTP request in step S129e, the web server device 30 refers to its own database based on the received HTTP request and searches for real estate property information that matches the search condition in step S129f. Then, in step S129g, the web server device 30 creates an HTML-format web page indicating the search result screen, and in step S129h, transmits the HTML data as an HTTP response to the user terminal 10. In step S129i, the user terminal 10 receives the HTTP response. In step S129j, the user terminal 10 converts the character code of the received HTML data into an appropriate one in the same manner as described above. In step S129k, The HTML data is analyzed using an API provided by Java (registered trademark) or the like for analyzing the HTML data.

  Subsequently, as shown in FIG. 33, the user terminal 10 determines whether or not there is a search result on the website in step S129l. Here, if it is determined that there is no search result on the website, the user terminal 10 determines that there is a search result on the website while ending a series of real estate property information data acquisition processing. In such a case, in step S129m, the real estate property information data is extracted from the HTML data as described above with reference to FIG.

  Subsequently, when the user terminal 10 extracts the real estate property information data in this way, in step S129n, the user terminal 10 determines whether or not all the real estate property information data has been extracted from the HTML data. When the real estate property information data is extracted, in step S129o, the data format is converted in accordance with the format of each column constituting the property data storage table as the storage destination. At this time, as described above, the user terminal 10 converts the display format of the real estate property information data different for each website into a unified display format.

  When the user terminal 10 converts the real estate property information data into an appropriate data format in this way, in step S129p, the real estate property information data is stored in the property data storage table, so that it is shown in FIG. A property data table consisting of various real estate property information data is created. Then, in step S129q, the user terminal 10 determines whether or not the next page exists in the search result. If it is determined that the next page exists in the search result, the process proceeds from step S129a in FIG. On the other hand, if it is determined that the next page does not exist in the search result, a series of real estate property information data acquisition processing ends.

  The user terminal 10 performs the acquisition process of the real estate property information data in parallel for all websites selected by the user, and waits for the processes for all the websites to end. Thus, the process proceeds to step S130 in FIG. In step S130, the user terminal 10 refers to the variable [sort_options] described above, and extracts real estate property information data from the property data storage table according to the display order of the list of search results input and designated by the user. . Then, the user terminal 10 creates a search result screen in step S131, displays the search result screen on the display unit 17 in step S132, and ends the series of processes.

  In the real estate property information search system, through a series of such processes, an HTTP request and an HTTP response are exchanged between the user terminal 10 and the web server device 30, respectively, and a plurality of real estate agents You can search real estate property information from the website.

  As described above, in the real estate property information search system shown as the second embodiment of the present invention, the real estate property information search program is executed by the user terminal 10 to access a plurality of web server devices 30. Then, the real estate property information posted on the plurality of existing websites can be obtained by causing the plurality of web server devices 30 to perform the search according to the search conditions input and designated via the user terminal 10. It can be set as a search target, and desired information can be searched from these real estate property information very easily and efficiently in accordance with one-time search condition designation by the user, and provided as a list.

  Here, since the real estate property information search system does not go through the search server device 20 as in the first embodiment, the search server device 20 is obtained by accessing a large number of user terminals 10 all at once. In addition, the time required for processing for sending and receiving the HTTP request and the HTTP response between the search server device 20 and the user terminal 10 can be shortened. Furthermore, in the real estate property information search system, by distributing to the user as a dedicated real estate property information search program, it is possible to provide the user with a screen that can express richer than a web browser. In particular, in the real estate property information search system, a real estate property information search program is created using so-called VB (Visual Basic) or the like, and a graphical user interface (Graphical) such as buttons and icons for realizing various functions. User Interface (GUI) can be customized by the user himself, and extremely high convenience can be provided to the user.

  The present invention is not limited to the embodiment described above. For example, in the above-described embodiment, it has been described that a web page described in HTML is handled. However, the present invention is a case where a web page described in other markup languages such as XML is handled. Can also be applied easily. In particular, in the real estate property information search system, when handling a web page described in XML, the real estate property information data extraction process in step S55m shown in FIG. 22 or step S129m shown in FIG. Is advantageous in that it can be performed more efficiently than when a web page described in HTML is handled.

  In the first embodiment described above, information input and designated by the user terminal 10 is transmitted to the search server device 20, and a search result based on the information is sent from the search server device 20 to the user terminal 10. However, the present invention can also be used as a search engine specialized in searching for real estate property information on an information providing site provided by another information provider such as a portal site.

  In other words, the real estate property information search system may include an information providing server device owned by another information provider between the user terminal 10 and the search server device 20, although not particularly illustrated. In such a real estate property information search system, the user terminal 10 searches for real estate property information that is designated and input via a predetermined web page provided from an information providing server device possessed by another information provider. A predetermined search condition is transmitted to the information providing server device. In response to this, the information providing server device transmits information indicating the search condition or the like to the search server device 20 as HTML data, XML data, or the like. A search request for real estate property information that matches the search condition input and designated by the terminal 10 is made. Subsequently, as described above, the search server device 20 matches the search conditions specified by the user terminal 10 for the plurality of web server devices 30 based on the search request from the information providing server device. A search request for real estate property information to be made is made, a search result as the search server device 20 is created based on the obtained individual search results, and this information is sent to the information providing server device as HTML data, XML data, or the like. Send to. Then, the information providing server device creates a search result screen as a final search result based on the search result transmitted from the search server device 20, and transmits the search result screen to the user terminal 10 for display on the display unit 17. Display.

  In this way, in the real estate property information search system, another information providing site prepares a screen as an interface for the user, and data on search requests and search results between the information providing server device and the search server device 20 is stored. The present invention can also be applied to a case where transfer is performed in a form that the user is not aware of.

  Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
