And the server apparatus 1, the user's information terminal 2, and the web server 3 which manages a merchandise site etc. are connected so that communication is possible via the networks 4, such as the internet. The user information terminal 2 conceptually includes various devices such as a smartphone, a tablet terminal, a notebook computer, and a desktop computer.

  In such a configuration, the user can receive an appropriate size presentation service by accessing the portal site provided by the server device 1 by the information terminal 2. Alternatively, the user can receive an appropriate size presentation service by accessing the product site provided by the web server 3 using the information terminal 2 and transferring the product site to the portal site provided by the server device 1 from the site.

  The server device 1 receives data of the category of the product selected by the user, the brand, and the size of the product of the brand that has been purchased, and also includes quantitative height data and qualitative physical characteristics. The estimated width is calculated by referring to the statistical data specified by the category, brand, and size of the product, and the size that minimizes the difference between the estimated width and the actual measured width of the product is determined. A predetermined coefficient is obtained from the feature data using statistical data, and the estimated length calculated based on the height data is multiplied by the coefficient to obtain at least one of estimated length, estimated sleeve length, and estimated bottom length. Determine whether they are within the recommended range.

  FIG. 2 shows and describes the configuration of the server device in the system in more detail.

  As shown in the figure, the server device 1 includes a control unit 11 such as a CPU (Central Processing Unit). The control unit 11 is connected to the communication unit 12 and the storage unit 13 via the system bus 16. The communication unit 12 communicates with the user information terminal 2 and the web server 3 that operates the product site via the network 4. The storage unit 13 includes a memory such as a RAM and a ROM, a hard disk drive (HDD), and the like. Logically, a user database (hereinafter referred to as DB) 14 that holds user information and a clothes DB 15 that holds clothes information are provided. The storage unit 13 holds a control program, and provides a work area when executing the control program.

  The control unit 11 reads and executes the control program 17 in the storage unit 13 to thereby execute a main control unit 11a, an input processing unit 11b, a data collection unit 11c, a reference value calculation unit 11d, an appropriate size calculation unit 11e, and display data generation. It functions as the part 11h. The appropriate size calculation unit 11e is further roughly divided into a width estimation unit 11f and a height estimation unit 11g.

  In such a configuration, the input processing unit 11b receives data on the category of the product selected by the user, the brand, and the size of the product of the brand that has been purchased, and also includes quantitative height data, And accepting qualitative physical feature data.

  In the appropriate size calculation unit 11d, the width estimation unit 11f calculates an estimated width with reference to statistical data specified by the category, brand, and size of the selected product, and the difference between the estimated width and the actually measured width of the product Specify the size that minimizes. In the appropriate size calculation unit 11d, the length estimation unit 11g obtains a predetermined coefficient from the physical feature data using statistical data, and multiplies the estimated height calculated based on the height data by the coefficient, At least one of the estimated sleeve length and the estimated bottom length is obtained, and it is determined whether or not they are within the recommended range.

  Then, the display data generation unit 11h generates display data in order to present the specified size and / or estimated width, estimated length, estimated sleeve length, and estimated bottom length to the user in a qualitative output manner.

  The data collection unit 11 c periodically accesses the web server 3 and collects data by crawling from a website provided by the server 3. The reference value calculation unit 11d cleans and captures the collected data, and calculates a reference value from the captured data. The calculated reference value is stored in the clothes DB 15. The statistical data used in calculating the estimated width by the width estimating unit 11f described above is this reference value.

  When estimating the length by the height estimation unit 11g, the coefficient is calculated by referring to the statistical data using the qualitative physical feature data, and the self-recognition-based physical feature input by the input processing unit 11b is calculated. Based on this, the length is estimated by multiplying the corresponding coefficient. For reflection in the output result, the relationship between the length and width of clothes is expressed using a gauge. For example, for users who answered “long” when inputting physical features in terms of arm length, use statistical data to multiply the user's distribution that seems to be relatively long by estimating the length. I do. More specifically, for example, the arm length is estimated from the height data, and 6.5% is added as a coefficient thereto. Details of this will be described later.

  In addition to the above, the main control unit 11 a performs overall control such as transmission control of display data to the information terminal 3.

  FIG. 3 shows and describes the configuration of the user information terminal in the system in more detail.

  As shown in the figure, the information terminal 2 includes a control unit 21 such as a CPU. The control unit 21 is electrically connected to the communication unit 22, the operation unit 23, the display unit 24, and the storage unit 25 via the system bus 27. The communication unit 22 is an interface that communicates with the server device 1 and the web server 3 via the network 4. The operation unit 23 is an operation device such as a mouse or a keyboard. The display unit 24 is a display device such as a liquid crystal display. The operation unit 23 and the display unit 24 may be integrated as a touch panel. The storage unit 25 includes a RAM, a ROM, an HDD, and the like, holds the control program 26, and provides a work area when the program is executed.

  The control unit 21 functions as the main control unit 21a, the browsing unit 21b, and the display control unit 21c by reading and executing the control program 26.

  In such a configuration, the browsing unit 21b accesses the portal site provided by the server device 1 and the product site provided by the web server 3 and enables browsing of the web page. At the time of browsing, the display control unit 21c performs display control by the display unit 24 based on display data such as HTML from the server device 1 or the like. The main control unit 21a performs overall control such as communication with the server device 1.

  Hereinafter, with reference to the flowchart of FIG. 4, a processing procedure of data collection processing by the system will be described in detail.

  In the server apparatus 1, the data collection unit 11 c collects data by crawling from a website provided by the web server 3 at a predetermined timing (S 1), cleans and collects the collected data, and stores the clothes DB 15. (S2).

  Here, in the crawl in step S1, the process of downloading and analyzing a pre-registered web page and downloading the page when a link to another page is included is repeated one after another. Collect data. The data collected by crawling includes a site name, sex related to the product, brand, category, size, site related to the product and its dimensions.

  On the other hand, in the data cleaning in step S2, deletion, correction, normalization is detected by detecting duplication, misrepresentation, shaking of notation, etc. in relation to newly collected data from the data already stored in the clothes DB 15. Update while doing.

  More specifically, for example, first categorized into large categories (tops, dresses / tunics, outerwear, bottoms, etc.), followed by small categories (T-shirts / cutsews, knits / sweaters, sweatshirts, shirts / blouses, dresses / tunics, Coats, jackets, skirts, pants, denim, etc.). Following this, specify the length (length, sleeve length, skirt length, bottom length, etc.) and width (width, waist width, cross width, hip width, etc.) corresponding to each part name, and further specify the dimensional magnification. However, it takes in while taking care of notation fluctuations and misrepresentations.

  In this way, the reference value calculation unit 11d reads out the data captured from the clothes DB 15, calculates the reference value based on a statistical method (S3), updates the reference value held in the clothes DB 15 (S4), The process ends. In calculating the reference value, the products are categorized according to the gender, large category, brand, small category, part, and size of the product, and the reference value is calculated for each categorized product.

  Next, with reference to the flowchart of FIG. 5, a main processing procedure related to presentation of an appropriate size by the system will be described in detail.

  When the process related to the appropriate size presentation is started, the input processing unit 11b receives and processes the selection of sex (S11). More specifically, when a gender selection screen is displayed on the information terminal 2 of the user and gender (male / female) is selected on the gender selection screen, the gender data is sent to the server device 1 and an input processing unit 11b processes the sex data.

  Subsequently, the input processing unit 11b receives and processes a brand selection (S12). More specifically, a brand selection screen is displayed on the information terminal 2 of the user, a large category (tops, outer, bottoms, etc.) is selected on the brand selection screen, a brand is selected, and a small category (T Shirt / Cut / Sew, Knit / Sweater, Sweat, Shirt / Blouse, Coat, Jacket, Pants, Denim, etc.) and size (S, M, L, LL, etc.) are selected. The data is sent to the server device 1 and the input processing unit 11b processes the brand data.

  Subsequently, the input processing unit 11b receives and processes the input of physical features (S13). More specifically, a physical feature input screen is displayed on the information terminal 2 of the user, and quantitative data of height, weight, and age is input on the screen, and a qualitative selection regarding the physical features is made. Then, these physical feature data are sent to the server device 1, and the input processing unit 11b processes the physical feature data. For qualitative selection regarding physical characteristics, for example, if the large category is tops and outer, select the level for arm length, torso length, and waist thickness, and if the large category is bottoms, select the waist. You may make it select the level regarding the thickness of the body, the size of the hip, and the size of the thigh.

  Subsequently, the appropriate size calculator 11e calculates an appropriate size (S14). The processing procedure related to the calculation of the appropriate size will be described in detail later with reference to FIG. 6. The width estimation unit 11f estimates the width, the recommended size is specified, and the height estimation unit 11g estimates the height.

  In this way, the display data generation unit 11h generates display data for the calculation result by the appropriate size calculation unit 11e (S15). With the above, a series of processes related to the appropriate size presentation is completed. This display data is transmitted from the server device 1 to the user information terminal 2 and presented on the information terminal 2. Therefore, when the user selects the recommended size and the recommended size, the user can check how the length is related to his / her physical characteristics in a qualitative output mode.

  Here, the procedure of the appropriate size calculation process executed in step S14 of FIG. 5 will be described in more detail with reference to the flowchart of FIG.

  When entering this process, the width estimation unit 11f reads the reference value of the size of the previously selected brand from the clothes DB 15, and uses the reference value as the estimated width of the user (estimated width of the body, estimated waist width, estimated hip width, and estimated (Sliding width, etc.) (S21). Then, the width estimating unit 11f specifies a size having the smallest difference between the estimated width and the clothes width (the width of the body, the width of the waist, the hip width, the crossing width, etc.) as the recommended size (S22). In this example, when the difference between the two is within 8%, it is determined to be within the recommended range, but the present invention is not limited to this.

  Subsequently, the length estimation unit 11g calculates the dimensions of each part of the user's body from the height data of the user DB 14 (S23), and the length (length, sleeve length, bottom length, etc.) based on the dimensions of each part of the body. Is calculated (S24). When estimating the length by the height estimation unit 11g, the coefficient is calculated by referring to the statistical data using the qualitative physical feature data, and the self-recognition-based physical feature input by the input processing unit 11b is calculated. Based on this, the corresponding coefficient is multiplied to estimate the length.

  Then, the length estimation unit 11g determines whether the calculated length (length, sleeve length, bottom length, etc.) is within a predetermined recommended range (S25), and displays a display mode (for example, in relation to the recommended range) , Stepwise gauge level setting, etc.) are specified (S26). Thus, the process returns to step S in FIG.

  Finally, FIG. 7 shows a display example on the information terminal and will be described.

  As shown in the figure, the recommended size is displayed, and the length, sleeve length, and width are displayed in a leveled display (in this example, a gauge display) so that the fit can be understood. Yes. This is an example, and the present invention is not limited to this.

  As described above, according to one embodiment of the present invention, by acquiring and maintaining the reference values of various brand sizes (S, M, L, LL) as statistical data by periodically crawling the product site. Since the user can calculate the estimated width of the user simply by selecting (input) the product category, brand, and size, it is not necessary to input quantitative data for each physical part in order to present an appropriate size. , The burden on the user is reduced. Furthermore, since the fine adjustment using the coefficient can be performed in calculating the estimated height based on the input qualitative physical feature data, it is possible to appropriately present the fit.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this, and it is needless to say that various improvements and changes can be made without departing from the spirit of the present invention.

  For example, the input (selection) items of qualitative physical features are not limited to those described above, and various other inputs may be prompted to be used for calculating the estimated height.
