That is, the real-time bidding information providing system 20 updates the bidding information updated or added by the web server 35 of the ordering unit 30 through the search robot 29 at a predetermined period, for example, 5 minutes, 10 minutes, or When the information is updated or added to the bidding information in a one-hour period, the information is classified according to a predetermined format and stored in the database 28 of the web server 25 of the bidding information providing system. Information is displayed and provided at the request of the user 10. Here, the database of the bidding information providing system includes a pageview log database 515, a user information database 516, and a bidding information database 517 shown in FIG. 5.

On the other hand, according to the learning process of the search robot as shown in FIG. 5 to be provided to the user 10 via the World Wide Web (www) and e-mail (e-mail).

The bidding information robot 29 searches and monitors the web server 35 of the ordering unit 30 for 24 hours, and immediately checks the basic information collecting main routine and the data collecting main routine shown in FIGS. 2 to 6 for updated or added information. Through the above, it is stored in the database 28 of the web server 25 of the bidding information providing system 20.

Hereinafter, the operation of the bidding information robot 29 will be described. The bid information robot 29 of the bidding information providing system 20 requests a page in which the bidding information is stored via the connection part 31 and the interface part 32 of the ordering part 30.

The operating system 33 of the ordering unit 30 interprets the Internet protocol 34 and transmits the page requested by the bidding information robot 29 to the web server 35. The web server 35 searches the database through the database manager 36 and transmits the result to the bid information robot 29.

The bid information robot 29 analyzes the format of the page in which the received bid information is recorded and the like, and adds or updated the information to the database manager 26 through the duplication check and the automatic classification subroutine shown in FIGS. 4A and 4B. Send it and store it in the database 28.

This will be described in detail with reference to FIGS. 2 to 6.

2 is a flowchart showing the main routine 1 of the basic information collecting process of the bidding information robot 29 of the bidding information providing system 20 according to the present invention.

The main routine 1 of the basic information collection process is a process of collecting and storing basic information about the homepage of the ordering unit 30, which is a target for collecting bidding information, and only once for the first time before the main routine 2 of the bid data collection process operates. Works. However, if the component of the bidding information of the target homepage is greatly changed, it is executed again.

First, the homepage address of the ordering party where the bid information list exists is manually input (step S101). The bid information robot 29 drives the hypertext transfer protocol (step S102) and checks whether or not the corresponding homepage exists (step S103). If the home page exists, the page is read and the entire page is stored as a variable (step S104). The bidding information robot 29 analyzes the table structure of the entire homepage (step S105), finds a repeating pattern (step S106), and inputs it to the database 28 based on the topmost pattern of the repeating pattern (step S109). After determining the required field name (steps S107 and S108), after inputting the information of the corresponding homepage into the database (step S109), the main routine 2 (Fig. 3) of the data collection process is performed.

3 is a flowchart showing the main routine 2 in the process of collecting the actual bid information of the bid information robot 29 of the bid information providing system 20 according to the present invention.

The main routine 2 of the bidding information gathering process reads the page containing the bidding information of the ordering unit 30, examines the existence of the added or changed bidding information, and collects the corresponding information, thereby providing the bidding information providing system of the present invention. The process of inputting to the database 28 of (20) is shown.

Main routine 2 of the bidding information collection process is automatically performed according to a time period (for example, 5 minutes, 10 minutes, or 1 hour interval) input by the scheduler.

First, the scheduler is driven (step S202), and log file generation is started (step S203). The web server 25 checks whether it is the designated time (step S204). If it is the designated time, basic information such as field information collected in Fig. 2 is read from the database 37 of the ordering unit 35 (step S205).

The Hyper Text Transfer Protocol is driven (step S206), and the validity of the target page is checked (step S207). That is, check the inadequacy of the page due to the server down or other reasons, if the page is inappropriate, generate a log (step S203), and then the main routine 2 of the data collection process until the next start time Withhold If it is determined that the page is appropriate, the number of repetition patterns of the corresponding home page is collected, and the number of repetition inspections is set (step S208).

The repetition pattern described above has the following meaning. Due to the nature of Hyper Text Markup Language (HTML), only limited methods are available for providing large amounts of custom information. That is, using a table tag (<table>). Therefore, the information has one pattern based on a row tag (<tr>) indicating a row among the table tags, and the number of these tags means the number of repeating patterns.

In the next process, the first one of the repetition patterns is analyzed and a valid string is parsed (the necessary string is extracted) (step S209). Here, a valid string means a string excluding a tag inside a cell tag (<td>) inside a row tag.

The suitability of the parsed character string data type is determined (step S210). For example, if another type of data is included in the position where the date type data should be located, the flow advances to the next pattern, and if appropriate, the data is assigned to each variable (step S211). The assigned variables perform a duplicate check process of the duplicate check subroutine 2-1 to be described with reference to FIG. 4 (steps S212 and S213). In the redundancy check process, if it is determined that the collected information overlaps with the existing bidding information of the database 28, the process returns to step S209 of retrieving a repetition pattern of other data and searches for other data.

If there is no overlap with the existing data, the page with the bid notice body is tracked (step S214). Next, a check is made to see if a bidding announcement page exists (step S215). If not present, the process proceeds to the next pattern, and if present, the type of bid is determined in the data classification subroutine 2-2 shown in FIG. 4B (step S216), and the bidding information providing system (with the data parsed above) 20 in the database 28 (step S216).

It is determined whether the end of the repetition pattern is end (step S217). If the repetition pattern is not the last, if not the last pattern, the process proceeds to the next pattern. If the repetition pattern is the last, the execution result report is created and transmitted to the administrator, and the execution result is stored in a file (step S218).

4A shows in detail the duplicate inspection subroutine 2-1 (steps S212 and S213) in the main routine 2 of the data collection process of FIG. 3 of the bidding information robot 29. In the duplicate inspection subroutine 2-1, FIG. This is a flowchart illustrating a process of determining bidding information overlapping with existing data.

The data collected from the data collection main routine 2 process of FIG. 3 is received (step S310). Examine whether the collected data is duplicated with the existing data in the site (step S320), and whether or not it overlaps with the entire bid data stored in the database 27 of the bidding information providing system 20 already viewed from other sites. To check (step S330). It is determined whether the bid information is duplicated through two overlapping checking processes (steps S340 and S350). The data collection main routine 2 of FIG. 3 is converted 360.

FIG. 4B is a flowchart showing in detail the process of data classification subroutine 2-2 (step S216) for automatically determining the type of bidding and the like for the data of successfully collecting the bid body in the data collection main routine 2 of FIG. .

In the main routine 2 of the data collection process of FIG. 3, data serving as a classification standard is read from the database 28 of the bidding information providing system 20 (step S401). The word index serving as the classification standard is read from the database 37 of the ordering unit 30 (step S402). In step S404, the two are compared. In step S405, it is determined whether there is a matching character string. If there is a matching character string, a classification code is set (step S405), and the process goes to step S407 in which it is determined whether or not the comparison is complete. If the comparison is not complete, the process returns to step S404 to perform the comparison. When the comparison is completed in step S407, it is determined in step S408 whether one or more classifications are set. If more than one classification is set, the classified code is switched to the data collection main routine 2 of FIG. 3 (step S410), and if not more than one classification is made, unclassified data is set (step S409), and FIG. Switch to the data collection main routine 2 of (step S410).

FIG. 5 illustrates a process of learning a user's search tendency when a bid information robot manager 27 requests bid information, that is, when searching for bid information, and applying the same to a personalized personal information part. This is a flowchart.

Prior to the description, the page view log database 515 means a database storing a page requested by a user together with a user's ID, and the user information database 516 refers to a database storing a list of personalized personal information of the user. The page view log database 515 and the user information database 516 are provided separately from the database 28 of the bidding information providing system 20 shown in FIG.

The database 516 allows the user 10 to enter his or her personal information (ID, password, address, etc.), general personal information, interests, and the like.

The page view log database 515 accesses the bidding information providing system 20 according to the present invention when the user 10 entered into the database 516 retrieves the bidding information provided by the system 20. It is a database for learning the form of search. For example, when a user connects to the system 20 and searches for a building interior construction area in a bidding announcement of a metropolitan area such as Gyeonggi or Seoul, the user may select an area of interest based on the personal information stored in the database 516. Learn and add to your personalized list of personal information.

The personalized personal information list means a list of information desired by each user, that is, a field of interest, by selecting information required by the user 10 for each item.

Hereinafter, a process of learning the search tendency of the user 10 will be described with reference to FIG. 5.

First, in FIG. 5, the bidding information providing system 20 of the present invention receives an information request from the user 10 (step S501). In this case, the system 20 displays the page requested by the user 10 and checks whether it is included in the customized personal information request list in the existing user information database 515 (step S502). If the requested page is determined whether or not the personalized personal information request list is present (step S503). If the requested page is present in the personalized personal information request list, according to the request for the personalized bid information of the user 10 stored in the database 517, the personalized bidding information is performed by performing the publishing main routine 4 shown in FIG. 7 (step S520). Perform the publishing main routine 4 to display or print the page.

If it does not exist in the customized personal information request list, the page view log database checks whether it is a new page view (step S504). In the case of a new page view, the user's ID and the requested page are stored in the page view log database 515. If the page has been requested before, 1 is added to the number of page views and rewritten (505). Switch to the publication main routine 4 (step S520).

When the next user requests the personalized personal information (507), the bid information robot manager 27 checks whether to apply the learning process (step S507). If the learning process is not applied, the personalized information is called from the bid information database 28 (step S513), and then switched to the publishing main routine 4 of FIG. 7 (step S520), so that the bid information page requested by the user 10 is displayed. Display.

If the learning process is applied, the user information database 516 and the page view log database 515 are taken (step S509), and it is recommended to add a plurality of requested pages to the customized user personal information list (step S510).

If the user wants to add the current requested page to the customized user personal information list, the information list added to the user information database 516 is recorded, and the information is called based on the information list applied to the learning process (step S513). (7), if the user does not want to add, delete the applied learning process (step S512) and call the existing information list (step S513). Switch to the publishing main routine 4 of step 7 (step S520).

Here, when the user 10 selects a personalized personal information list, the database manager 26 of the bidding information providing system 20 according to the present invention stores information corresponding to the personalized personal information list of the user 10 in a database ( 28, it is possible to send the updated data to the user 10 via e-mail. FIG. 6 is a flowchart showing a publishing main routine 4 for unifying the design of the bid body page collected by the individual orderer 30 to improve readability.

In step S600, the learning robot requests a bid information page. The database 28 is searched by this page request to determine whether or not the page requested by the user 10 exists (step S602). If the request page exists, the corresponding information is read from the database 28 (step S603).

Next, it is determined whether the data requested by the user 10 is in Hyper Text Markup Language (HTML) format (step S604). In the case of the HTML format, a design change operation through paragraph processing, table design conversion, color tone, font, and font size conversion is performed (step S605). If it is not in the HTML format, the process proceeds to step S606 to improve readability by performing line spacing optimization through CR, LF, and tag processing, and image processing of special symbols.

In step S607, link processing in the content, call format processing, and additional information according to the type of information are processed. In step S608, the page requested by the user 10 is output.

Here, the output of the page means that the user can view the requested bid information page, which is displayed on the computer monitor.

Effects of the invention according to the embodiment of the present invention are as follows. First, instead of manual work, the bidding information robot inputs and manages bidding information, thereby saving huge manpower and cost time.

Second, it is possible to provide real-time bidding information while tracking, monitoring, and updating the website of the owner 24 hours a day.
