Description

Description of the Related Art [0002] A method of collecting minimum price information of an Internet shopping mall and a method of updating product information using collected minimum price information }

The present invention relates to a method for a service server of a price comparison site to collect product information including price information of a specific commodity in an Internet shopping mall, and to quickly update the price information of the price comparison site by reflecting it.

The selling price in the Internet shopping mall differs for each Internet shopping mall even if the product is the same.

Therefore, the buyer wants to purchase the goods at the internet shopping mall which offers the lowest price for the same goods. To help the buyer, the buyer collects the price information of the various internet shopping malls and provides information for comparison at a time The sites appeared.

That is, the price comparison site provides the list on the web page in which the goods of the relatively low price and the goods of the relatively high price are sorted in the same product by using the collected goods information so that the buyer can easily and economically It helps to purchase the goods at the price.

There are many price comparison sites in Korea, including Danawa (www.danawa.com), Enuri (www.enuri.com), Bibi (www.bb.co.kr), Naver Knowledge Shopping (shopping.naver.com) Are well known.

Competition among these price comparison sites is generally dependent on the ability to search for the lowest priced shopping mall for a particular product.

In other words, as the number of products for which a specific price comparison site presents the lowest price lower than other price comparison sites, the sales of the comparison site are more likely to increase.

Therefore, operators of price comparison sites will try to expose more of the lowest price products on their site than other price comparison sites.

However, because all price comparison sites update the lowest price information from time to time so that the products exposed on their site always show the lowest price than other price comparison sites, Holding and exposing more information is not easy.

In general, the operator of the price comparison site collects the selling price information of the Internet shopping mall at any time in order to expose the products of his site at the lowest price than other price comparison sites, and updates the price information of the own price comparison site. The update method can be divided into a manual update method and an automatic update method.

The manual update method is a method in which a price comparison site operator monitors price of goods exposed on a web page of another price comparison site and collects price information of a product having a lower price compared to the price comparison site of its price comparison site , A method of directly updating the price of goods on the self price comparison site with a lower minimum price or allowing the actual seller to decide the update.

In the automatic updating method, the service server of the price comparison site periodically or temporarily receives the service server from the Internet shopping mall, or directly accesses the web page of the specific product of the Internet shopping mall to collect price information, This is a method of determining whether or not to execute the minimum price update in comparison with the price information.

Among the automatic updating methods, a method of receiving product information including prices from an Internet shopping mall in regular or irregular periods is a method of receiving product information data from an Internet shopping mall to a price comparison site, So that the minimum price update is performed. However, if the price information of the Internet shopping mall is changed during this time interval, the price comparison site can not immediately know that the price information is transmitted to the price comparison site. Therefore, There is a problem that the price information can not be quickly reflected.

On the other hand, among the automatic updating methods, a method of directly accessing a web page for a specific product of the Internet shopping mall and updating the product price is as follows.

(a) The price comparison site service server drives a crawler and accesses an Internet shopping mall site that needs to be searched.

(b) When the crawler searches the Internet shopping mall and finds a commodity sales web page, the crawler indexes commodity information such as a commodity name and a price, and transmits the indexed commodity information to the price comparison site service server.

(c) The price comparison site service server parses the indexed product information to determine whether the product matches the product included in the reference product stored in its product information DB.

(d) If the goods match, the price comparison site service server compares the price information of the collected goods with the price information stored in the goods information DB.

(e) If the price information of the goods collected from the price information stored in the goods information DB is displayed at a low price as a result of the comparison of the price information, the price comparison site service server stores the price information stored in the goods information DB in the collected goods Quot; is updated.

However, in order to collect product information of the Internet shopping mall by crawling as described above, the address (URL) of the sales product web page of the Internet shopping mall, which is generally matched with the individual reference product of the price comparison site, In advance.

That is, the crawling is performed on the product web page URL of the stored Internet shopping mall. Since the URL exists for all of the hundreds of millions of goods held by the Internet shopping mall, if all of them are crawled, Thereby causing a problem of causing traffic. In addition, the Internet shopping mall frequently changes the URL of the web page of the goods possessed, and therefore, the crawl is often not performed properly.

In addition, the crawled information is collected by the server of the price comparison site by parsing, and when the amount of crawled information is too large, the parsing takes a long time.

Here, the term 'reference product' used in the present invention will be described. In many cases, there are differences in how product information is displayed for each online shopping mall, even if the same product is used. Therefore, Means a product that has been corrected. Therefore, even if there is a difference in notation method or the like in each Internet shopping mall, the same goods can be effectively compared with the reference goods of the price comparison site to which the goods belong.

A method of collecting price information of an Internet shopping mall by crawling and parsing as described above can be partially confirmed in Korean Patent Laid-Open Nos. 10-2013-0011620 and 10-2011-0136201.

Conventional techniques for generating and presenting a lower commodity price compared to a competitor in an Internet shopping mall or a price comparison site are disclosed in Korean Patent Laid-Open Nos. 10-2010-0011839 and 10-2010-0011840.

FIGS. 2 and 3 are diagrams illustrating a method of collecting the lowest price information of the Internet shopping mall of the present invention, Fig. 8 is a diagram showing a method for updating product information using the product information.

1, the system for collecting the lowest price information of the Internet shopping mall according to the present invention includes a price comparison site service server 10, a database 20, an Internet shopping mall site 30, 40, and the Internet network 50.

More specifically, the price comparison site service server 10 exchanges information with the commodity manager terminal 40 and the Internet shopping mall site 30 via the Internet network 50, And provides the input means for inputting the lowest price information and the product information of the commodity manager of the commodity manager terminal 40 to the commodity manager terminal 40 . Of course, the price comparison site server also has a crawl module for crawling.

The database 20 stores operating information for operating a price comparison site and various goods-related information, and may be configured in the price comparison site service server 10 or may be configured as a separate external device. The database 20 includes a product information DB in which information such as a product name, a product price, and the like is stored.

The Internet shopping mall site 30 includes a shopping mall site (for example, G-market, auction, 11-avenue and Interpark) for selling various goods online, a price comparison site for comparing the shopping mall sites and comparing the price information Such as Enuri, Danawa, Bibi, and Naver Knowledge Shopping.

The commodity manager terminal 40 exchanges information with the price comparison site service server 10 and / or the Internet shopping mall site 30 through the Internet network 50. The 'commodity manager' using the commodity manager terminal 40 may be a system operator of a company that operates a price comparison site or may be a seller who sells commodities in the Internet shopping mall.

The commodity manager terminal 40 has a function of confirming the lowest price information of the commodity provided from the price comparison site service server 10 and modifying the commodity price information on the price comparison site managed by the commodity manager or the Internet shopping mall accordingly do. The commodity manager terminal 40 may include a PC, a mobile phone, a smart phone, a tablet, a netbook, a PDA, and the like capable of Internet communication.

The Internet 50 is a network such as a TCP / IP protocol that can be connected with a wired connection through various devices capable of computing and a WAP protocol that can be wirelessly connected to the Internet 50. The Internet 50 includes LAN, Wi-Fi, 3G / 4G, Means relay network.

Hereinafter, with reference to FIG. 2 and FIG. 3, a method of collecting the lowest price information of the Internet shopping mall according to the present invention and a method of updating product information using the collected lowest price information will be described.

[Example 1]

Embodiment 1 of the present invention is based on that it includes the steps A to S (S50) shown in FIG.

Step S10 is a step in which the service server 10 of the price comparison site drives a crawler to access the Internet shopping mall site 30 that needs to be searched. That is, when the price comparison site service server 10 executes the crawler module and drives the crawler module, the crawler accesses the Internet shopping mall site 30 designated by the price comparison site service server 10 through the Internet network 50.

In step S20, the crawler connected to the Internet shopping mall site 30 accesses the list page URL of the specific product category to collect the product information including the price information, To the service server 10 of the site.

Here, the list page of the Internet shopping mall site refers to a web page showing a list of specific goods being displayed online as shown in Figs. 4 and 5, and most Internet shopping mall sites have such a list page as an essential configuration.

For example, Auction, an Internet shopping mall, constructs and maintains a list page of LED TV products as shown in FIG. 4. As of the filing date, the URL is "http://listings.auction.co.kr/category/list.aspx?category=29470000".

In addition, the price comparison site, DanaWa, constructs and maintains a list page of the LED TV product as shown in FIG. 5 as a capture screen. The URL as of the filing date is "http://prod.danawa.com/list/?defSite=ELEC&cate_c1=149&cate_c2=180&cate_c3=15527".

In general, the order in which items are sorted in the list page is ranked according to the order in which the purchasing preference of the buyer is high. As shown in FIG. 4 and FIG. 5, all the products sold in the Internet shopping mall are exposed to the products belonging to one category on the list page.

In addition, this list page must include the product name and price information, which are basic product information of the sales product.

Therefore, according to the present invention, the crawler collects the product name and the price information, which are necessary product information, on the list page without entering the individual product-specific sales web page of the Internet shopping mall site, and thus the traffic generated on the server of the Internet shopping mall site due to the activity of the crawler It can be greatly reduced. Also, even if the URL of the web page of the specific product is changed by the Internet shopping mall side, the product information is always exposed on the list page, so that the crawler does not miss the product.

Meanwhile, in order to more effectively perform the crawling in the step B, a service server of the price comparison site may collect and index a pattern indicating a list page in URLs of various list pages of the Internet shopping mall. This indexing work can be realized by collecting the URL log information in the case of accessing the Internet shopping mall site via the service server of the price comparison site and analyzing a unique pattern denoting the list page for each Internet shopping mall site have. If the crawler is connected to the URL of the list page by using the indexed pattern, the processing speed and accuracy can be improved.

On the other hand, the crawler can hold keywords representing specific products. The crawler can collect only the product information including the keyword that matches the keyword held by the crawler among the product information of the list page, and send it to the service server of the price comparison site when accessing the URL of the list page. That is, if the keyword 'Samsung' is held in the crawler, it is possible to select only Samsung products among the products exposed on the list page and send the product information to the service server of the price comparison site. Therefore, It is possible to perform an operation efficiently in a short period of time.

In addition, as a general rule, if a buyer requests price information for a particular product category at a price comparison site, a list of hundreds to thousands of products can be exposed. However, except for the top dozens of products with the highest sales revenue among these sales products, the sales contribution of the remaining sub products is very small. Therefore, from the viewpoint of the operator of the price comparison site, it becomes substantially important to manage the lowest price information for the top dozens of products. Accordingly, if the crawler is configured to include a main product that affects sales, that is, a keyword that can identify each of the above-mentioned dozens of products, the crawler can store only the above-mentioned dozens of products, It is possible to select the list page of the site, parse the information of the included goods, and send necessary information, in particular price information, to the price comparison site service server. Therefore, in this case, not only the time required for crawling and updating the price can be greatly reduced, but also the occurrence of traffic on the Internet shopping mall site can be minimized.

Step C30 is a step of searching whether the price comparison site service server 10 has the same reference product as the corresponding product of the product information collected and transmitted by the crawler in the product information DB. For example, if the crawler collects merchandise information for the first merchandise on the list page of FIG. 4 as 'Samsung LED TV', model name is 'UN55H6350AF', and price is 1,617,110 won and transmits it to the price comparison site service server 10 , The price comparison site service server 10 finds product information corresponding to the model name 'UN55H6350AF' in the reference product 'LED TV'.

In step S40, the price comparison site service server compares the price information of the goods having the product information collected by the crawler with the lowest price information of the searched reference goods. That is, in the example of the above step C, since the model name is Samsung LED TV price information of Samsung LED TV of 1,617,110 won according to the product information collected by the crawler, the price comparison site service server 10 obtains the reference product 'LED TV Is compared to whether the price of the product matching the model name 'UN55H6350AF' is higher than 1,617,110 won.

If the price information included in the collected commodity information has a lower price than the lowest price information of the reference commodity stored in the commodity information DB (step S50), the price comparison site service server compares the lowest price of the reference commodity stored in the commodity information DB And updating the information with the price information of the collected goods. In the example of step D above, if the price of the existing product matching the model name 'UN55H6350AF' among the reference product 'LED TV' in the product information DB is 1,700,000 won, which is higher than the price information collected by the crawler, 1,617,110 won, The price information of the product information DB is updated to KRW 1,617,110. Accordingly, the lowest price of the LED TV having the model name 'UN55H6350AF' is exposed to KRW 1,617,110 on the web page of the price comparison site.

[Practical example 2]

The second embodiment of the present invention is based on that it includes step A (S10) to step E (S60) shown in FIG.

Steps A to D (S40) of Practical Example 2 are the same as those of Practical Example 1. Therefore, the description of Practical Example 1 is omitted.

If the price information included in the collected product information has a lower price than the lowest price information of the reference product stored in the product information DB (S60), the price comparison site service server stores the price information in the product information DB And transmitting the price information changing means of the products included in the reference product to the product manager.

That is, if the price information included in the collected goods information has a lower price, as described in step S50 of the first embodiment, the price comparison site service server 10 And transmits the generated price information changing means to the commodity manager terminal 40.

6 shows an example of the price information changing means 60 which is generated by the price comparison site service server 10 and transmitted to the commodity manager terminal 40. As shown in Fig.

6, the reference product 'MSI GS70-i7 Stealth' is registered and stored in the product information DB of the price comparison site service server 10 at the lowest price of 1,603,000 won at present, When the price of a product with the brand name "MSI GS70-i7 Stealth" in the product information of the Internet shopping mall turns out to be 1,501,000 won, it is approved to change to the lowest price of 1,501,000 won, which is the lowest price of the other internet shopping mall collected by the product manager To the commodity manager terminal 40 to illustrate the price information changing means 60 in the form of a web page.

When the price information changing means 60 of FIG. 6 is received, the commodity manager can click on the 'approve' button on the right side to allow the commodity manager to update the commodity price of his own goods exposed to the price comparison site service server 10 to the lowest price do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art, It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
