Abstract

PURPOSE: A method for managing a comparison site is provided to collect wanted commodity information in real time by transmitting a site list and query language information designated by a user to a JVM(Java Virtual Machine) of a user PC in a server side, creating a web robot in the user PC, and connecting to a corresponding site through the web robot. CONSTITUTION: A user connects to a PRIAG(Personalized Real-time Information Agent) server using a PC, and selects a wanted site in a comparison site list suggested in a homepage supplied in the server(S1,S2). The user inputs a proper query language for a comparison on a query language input space of the homepage(S3). The server receives the query language and transmits search information, that is, a site list and query language information selected by the user to a JVM of the user PC through the Internet(S4). The user PC creates a web robot by itself. The web robot searches a corresponding site based on the site list and query language information received from the server and collects necessary commodity information(site ID, firm name, model name, price, etc.)(S5,S6). The user PC arranges the collected commodity information in accordance with a request of the user and displays the commodity information on a screen(S7,S8).

Description

How to operate a comparison site {OPERATING METHOD FOR COMPARISON SITE}

The present invention relates to a technology for enabling comparative shopping by automatically extracting a list of items presented on the web, and in particular, prevents a large number of users from accessing the server and burdening a server or real-time information service for the user. How to operate a comparison site.

The e-commerce environment is fundamentally different from the existing distribution order, and it is expected to have a significant effect on the existing price system. In particular, due to the nature of electronic commerce connecting the world as well as domestic, the price of a certain product is applied worldwide. In general, when a buyer wants to purchase a product using e-commerce, if there is no difference in quality, he or she will buy at the store offering the most reasonable price.

However, as online stores are growing exponentially, they must invest a lot of effort and time to find the products they want. For example, if you use existing search engines to find the product you want, you may see pages that are completely unrelated to the product you are looking for or even spammed pages. In many respects, documents are ranked by criteria based on general information retrieval methodologies rather than by consideration. As another example, there is a directory service or a search engine dedicated to searching for product information manually managed by a person. Since this method is managed by a person, there is a delicate aspect. However, when the number of stores is large, it is difficult to maintain one by one. have. As another example, there is a method of getting product information by accessing a store in real time without using a database or a separate data store. This method has the advantage of presenting the most reliable information, but it uses parallel query technology. Even when used, there is a problem of slow search speed and weighted network traffic.

In this way, a proposed technique is proposed to solve the difficulty in finding a desired product in an e-commerce system. In this comparison site, a technology for providing comparison information for each Internet shopping site is described with reference to FIG. 1 as follows.

The web lottery 11 retrieves the product information from several information providing sites 30A and 30B previously set by the comparison site 10 and stores the product information in the database 13 so that the user can use the user PC 40. When the query is made through the Internet 20, the server 12 operates in a format that shows the contents stored in the database 13.

However, in the conventional comparison site, since the comparison result is provided only for a predetermined number of sites, there is a problem that the user can not select and compare only the desired site. In addition, since the price information provided to the user on the comparison site is 2-3 days old, there are often cases where the price is different from the current price.

In order to provide real-time information to a user, a site administrator must create one or more robots corresponding to each user connected to a server, and have the robots fetch and display information on various sites. However, in such a system, since the number of simultaneous access users increases, the number of robots generated when several queries are sent at once increases the burden on the management of robots in the server. In order to solve this problem, a technique of taking information into a user PC in advance and storing it in a database and showing a result of a database to a user is used. In such a case, a user cannot receive real-time information.

Therefore, an object of the present invention is to deliver the site list and query information specified by the user on the server side to the user's JVM, the user PC generates a web robot and then access the site through the web robot to the desired product information To provide a comparison site operation method to collect the data in real time.

10: comparison site 20: the Internet

30A, 30B: Informational Site 40: User PC

According to a first aspect of the present invention, a user provides real-time comparison information on a comparison target site without burdening the server.

According to a second aspect of the present invention, it is possible to obtain comparative information about a product for a site designated by a user.

The method for operating a comparison site according to the present invention includes a first step of receiving a query to be compared and selecting a comparison target site designated by the user on the server side after the user PC is connected to the PRIGA server; A second step of receiving, by the user PC, a site list and query information of a comparison target from the server and generating a web robot; The third step of the PC is to search the relevant sites based on the site list and query information using a web robot to collect the necessary product information in real time, sorted according to the user's request and displayed on the screen, When described in detail with reference to Figure 2 attached to the operation of the present invention as follows.

PRIGA (PRIGA: Personalized Real-time Information Agent) according to the present invention is produced similar to a normal comparison site, but unlike a normal comparison site personalization that operates to be suitable for collecting and displaying real-time information only at a site designated by a user Information gathering agent.

First, the user attempts to access the PRIGA server using his PC, and when the connection is successful, the user selects a desired site from the list of comparison target sites presented on the homepage provided by the server. In this case, the default site is selected automatically (S1, S2).

Accordingly, since the product information is obtained only from the site desired by the user, the personal tendency and taste of the user can be reflected.

Next, the user inputs an appropriate query to be compared in the query input box on the home page (S3).

The server receiving the query as described above passes the search target information, that is, the site list and the query information selected by the user, to the Java virtual machine (JVM) of the user PC through the Internet.

The user PC generates a web robot on its own, and the web robot searches the corresponding sites based on the site list and query information received from the server, and the necessary product information (eg, site ID, company name, product classification name, major name). Function, brand name, model name, price, URL, etc.) (S5, S6).

Therefore, the user can provide the desired product information in real time.

Thereafter, the user PC arranges the collected product information appropriately according to a user's request and displays it on the screen. (S7, S8)

For example, depending on the user's needs, each product can be sorted by price or by model and displayed on the screen.

For reference, a program may be constructed as a Java applet to perform the fourth to eighth steps S4-S8. The operation principle of the program is as follows.

It takes the user's query and site information as parameters and downloads it to the user's JVM. This operation is performed automatically, so no action is required from the user. After that, as many web robots as the number of sites selected by the user are generated in each user PC, each web robot accesses the corresponding site in real time and collects desired information. Each user PC collects the collected information in one place and arranges it in the form designated by the user and displays it on the screen.

According to another embodiment of the present invention, the PRIGA server may set up a database such as a comparison site in the PRIGA server to show the contents of the database first, and then show the result of updating in real time.

As described in detail above, the present invention does not generate a web robot for acquiring product information desired by the user in the electronic commerce system, but generates a user PC to collect the product information, thereby allowing a plurality of users to access the server. When connected to the server, there is an effect that it does not burden the operation of the server.

In addition, since the user robot collects information in real time by accessing the designated site, the web robot has an effect of improving the confidence in the product information.

In addition, by collecting the product information on the target site for the user to designate, there is an effect that can fully reflect the user's taste in the comparison site.
