For example, when the use of the purchased cosmetics is for skin care use, the second database generator 442 extracts the dose of the purchased cosmetics based on the purchase request signal and extracts the first database 450. If the filter is used according to the volume, and the use of the purchased cosmetic is a makeup use, the volume and color of the purchased cosmetic are extracted based on the purchase request signal, and the first database 450 is filtered according to the extracted volume and color. 2 may create database 460. However, this is only one example. When cosmetics are divided into various uses in the process of generating the first database 450, the second database may also be filtered by the classification criteria.

The third database generator 443 may generate the third database 470 by filtering the second database 460. The process of creating the third database 470 is as follows.

The brand name extractor 413 may extract a brand name of a purchased cosmetic product based on a purchase request signal.

The product name similarity calculator 414 may calculate the product name similarity by analyzing a degree of correspondence between the product name of each cosmetic product included in the second database 460 and the extracted brand name.

In more detail, the product name similarity calculator 414 may include a word extractor 431, a word classifier 432, a first weight reflector 433, and a product name similarity adder 434.

The word extractor 431 may extract a brand name of a purchased cosmetic product for each word. For example, the word extracting unit 431 may adopt a method of extracting words separated by the spacing when the brand name of the purchased cosmetics is spaced, and the manager who manages the cosmetic price comparison device 400 is provided. A method of extracting a word that can be identified by a word database (not shown) input through an administrator terminal (not shown) to be used may be adopted.

The word classification unit 432 may classify the extracted words into product detailed brands and usage description function words. For example, the product detail brand may be a trademark of a company that handles cosmetics to be purchased, and the use description function word may be a word indicating a function of cosmetics such as skin and lotion.

The first weight reflector 433 may calculate the similarity using the extracted words.

In more detail, the first weight reflecting unit 433 matches the words constituting the product names of the cosmetic products included in the second database 460 by applying the first weight to the classified product detailed brands. Analyze the first degree of similarity, and give a second weight to the classified use description function words to analyze the degree to match the words constituting the product name of each of the cosmetic products included in the second database 460 2 calculate the similarity, give a third weight to the arrangement order of the extracted words, analyze the degree of correspondence with the arrangement order of the words constituting the product name of each of the cosmetic products included in the second database 460 3 Similarity can be calculated.

The first similarity may be obtained by analyzing and quantifying whether the detailed brand constituting the product name of the purchased cosmetic product is identical or similar to the detailed brand included in each product name of the cosmetic products included in the second database 460. have.

The second similarity is analyzed whether the use description function word constituting the product name of the purchased cosmetic product is identical or similar to a word having the use description function included in each product name of the cosmetic products included in the second database 460. And may be quantified.

The third similarity analyzes whether the arrangement of words constituting the product name of the purchased cosmetic product is identical or similar to the arrangement of words included in the product name of each of the cosmetic products included in the second database 460. It may be quantified.

The weights given to the first to third similarities may be different. This may be due to the difference in the effects of detailed brands, usage description function words, and word arrangements on filtering the same product as the purchased cosmetics in the second database 460.

For example, since cosmetic brands generally have unique brands for each product line, when the detailed brands match, the first weight is higher than the second weight because the probability of the same cosmetics is higher than that of the words with the use description function. Can be large. In addition, in the case of the same product, since the arrangement of words constituting the product name is often displayed differently for each site, the third weight may be less than the second weight because it is relatively less important. However, this is merely an example, and weights may be changed at the discretion of the manager.

The product name similarity adding unit 434 may calculate the product name similarity by adding the first to third similarities.

The third database generator 443 may generate a third database 470 by selecting cosmetics having a product name similarity more than a set similarity among cosmetic products included in the second database 460.

The third database generator 443 may select a cosmetic product having a product name similarity higher than the set similarity by the product name similarity calculator 414 from among cosmetic products included in the second database 460, and then select a third database. 470 may be generated. The setting similarity can be adjusted by the administrator through the administrator terminal. While managing the cosmetic price comparison device 400, the manager can grasp the similarity that can generate accurate data by experience, and determine this as the set similarity.

The price comparison information transmission unit 415 may transmit price information of each cosmetic product included in the third database 470 to the candidate terminal 100, and the prospective purchaser who confirms the corresponding price information may purchase for each site 200. You can buy cosmetics at a lower price by comparing the prices of cosmetics.

As such, the product name of the purchased cosmetics is extracted for each word, and the cosmetics determined to be the same as the purchased cosmetics are extracted from the second database 460 in consideration of the function and arrangement of the extracted words. By extracting the same cosmetics that are sold and providing price information of the cosmetics to potential purchasers, the buyer can be provided with price comparison information with improved reliability and accuracy.

Furthermore, by injecting manpower from the manager's point of view, by manually extracting the same cosmetics as the purchased cosmetics and using the cosmetic price comparison device 400 that can provide accurate price comparison information for providing price comparison information to the prospective purchaser The cost for the service provided to the candidate can be reduced.

The product image extractor 416 may extract a product image of the purchased cosmetic product from the image of the purchased cosmetic product included in the purchase request signal. If there is no image of the purchased cosmetics in the purchase request signal, the product image extractor 416 may extract a thumbnail image of a product determined to be a purchased cosmetic on the web.

The image similarity calculator 417 may calculate an image similarity by analyzing a degree of correspondence between a product image of each cosmetic product included in the third database 470 and the extracted product image. (S70) One embodiment of the present invention. For example, the extracted product image may be an image of a package (case) of purchased cosmetics.

More specifically, the image similarity calculator 417 may include a second weight reflector 435 and an image similarity adder 436.

The second weight reflector 435 may extract attributes of the image and calculate similarities using the same.

In more detail, the second weight reflecting unit 435 assigns a fourth weight to the package (case) shape of the purchased cosmetics, so that the package (case) shape of each of the cosmetics included in the third database 470 is obtained. The fourth degree of similarity is calculated by analyzing the degree of coincidence, and a fifth weight is given to the color of the package (case) of the purchased cosmetic product, so that the package (case) of each of the cosmetic products included in the fourth database 480 is obtained. Analyzing the degree of matching with the color to calculate the fifth similarity, and give a sixth weight to the shape on the package (case) of the purchased cosmetics, each package (case) of each of the cosmetics included in the third database 470 The sixth similarity may be calculated by analyzing the degree of coincidence with the shape of the image.

The fourth similarity may be obtained by analyzing and quantifying whether the appearance of the package (case) of the purchased cosmetics is identical or similar to the appearance of each package (case) of the cosmetics included in the third database 470. .

The fifth similarity is analyzed by quantifying whether the color of the appearance of the package (case) of the purchased cosmetics and the color of the appearance of each package (case) of each of the cosmetics included in the third database 470 are identical or similar. It may be one.

The sixth similarity indicates whether the design displayed on the package (case) of the purchased cosmetic product is identical or similar to the design displayed on each package (case) of the cosmetic products included in the third database 470. It may be analyzed and quantified.

The weights given to the fourth to sixth similarities may be different. This may be due to the different influences of the shape, color, and design displayed on the package (case) in identifying the same product as the purchased cosmetics in the third database 470.

For example, in the case of an image, the appearance of the cosmetics is generally the appearance of the container in which the cosmetics are contained, so if the appearance of the containers coincides, the probability of the same cosmetics is highest, followed by the color of the container and the design on the container. The fourth weight may be greater than the fifth weight, and the fifth weight may be greater than the sixth weight. However, this is merely an example, and weights may be changed at the discretion of the manager.

The image similarity adder 436 may calculate the image similarity by adding the fourth to sixth similarities.

The fourth database generator 444 may generate a fourth database 480 by selecting cosmetics having an image similarity more than a set similarity among cosmetics included in the third database 470. The setting similarity can be adjusted by the administrator through the administrator terminal. While managing the cosmetic price comparison device 400, the manager can grasp the similarity that can generate accurate data by experience, and determine this as the set similarity.

The price comparison information transmission unit 415 may transmit price information of each cosmetic product included in the fourth database 480 to the candidate terminal 100, and the prospective purchaser who confirms the corresponding price information may purchase for each site 200. You can buy cosmetics at a lower price by comparing the prices of cosmetics.

As such, the cosmetics purchased may further filter the third database 470 to generate a fourth database 480 and provide price information of cosmetics included in the fourth database 480 to potential purchasers, thereby Received the price comparison information for each cosmetic sales site 200 with improved reliability can be purchased cheaply cosmetics based on this.

The cosmetic price comparison apparatus 400 may further include an exclusion database transmitter 418, a decision information receiver 419, and a cosmetic adder 420.

The exclusion database transmitter 418 may transmit the exclusion database including the cosmetics excluded in the process of generating the fourth database 480 to the candidate terminal 100.

The decision information receiving unit 419 is configured to determine the same decision information including the information of the cosmetic product which is determined to be the same as the cosmetic product purchased by the prospective buyer in the exclusion database and non-identical judgment information including information of the cosmetic product determined not to be the same. (100). (S90)

As shown in FIG. 6, the exclusion database transmitter 418 may transmit the exclusion database to the candidate terminal 100 in a form of requesting a purchaser to make a decision. In detail, the left cosmetic may be a photograph extracted by the product image extracting unit 416, and the right photo may be a product image photograph of one of the cosmetics belonging to the exclusion database. The exclusion database transmitter 418 may transmit a question requesting whether two cosmetics are the same cosmetic together with the pictures.

The prospective purchaser confirms the corresponding screen through the prospective terminal 100, and if it is determined that the same product is selected, selects Yes to generate the same judgment information, and if it is determined that the product is not identical, selects No to determine the same information. Can be generated. The generated identical determination information or non-identical determination information may be transmitted from the candidate terminal 100 to the determination information receiver 419.

The cosmetic adding unit 420 may include the cosmetics 490 of which the number of times included in the same determination information among the cosmetics included in the exclusion database is greater than or equal to a predetermined number of times for the purchase request signal received after the purchase request signal. It may be added to (480). (S100)

That is, in the process of generating the fourth database 480 from the third database 470, the cosmetic product included in the third database 470 that is the same as the purchased cosmetic product but is missing due to incorrect filtering is after the purchase request signal. The cosmetic adder 420 may add the cosmetics to the fourth database 480 with respect to the purchase request signal received in the.
