Description

METHOD OF MANAGING WEB SITES REGISTERED IN SEARCH ENGINE AND A SYSTEM THEREOF}

The present invention relates to a search engine that provides information about a given website on the Internet. More specifically, the present invention relates to a method for managing a registered website so that information about a predetermined website registered in a search engine is analyzed and a search result different from actual content included in the website is not provided. .

Conventional search engines such as AltaVista (http://www.altavista.com), Lycos (http://www.lycos.com), Yahoo (http://www.yahoo.com), and the like, typically have website information. A database for classifying, storing, and managing the data according to predetermined criteria, a search robot implemented as software for mechanically collecting new website information while continuously circulating on the web, and storing the collected data as a database. It consists of search engine software that allows a user using a search engine to search.

A block diagram of the entire system for providing an untapped search engine service is shown in FIG. 1A. Referring to FIG. 1A, a user accesses a search engine server 150 through the Internet through a user terminal 110. When a user enters a predetermined search term, the search engine server 150 queries the search engine software 140 for website information about the search term, and the search engine software 140 queries the corresponding database 130. Search and inform the website information. As described above, the search robot 120 is an entity implemented in software for mechanically collecting new website information from the web server 160 while continuously circulating on the web. The search robot 120 retrieves the text described in HyperText Markup Language (HTML) on the network, parses the described link and collects data from a number of websites present on the network. As such, the data collected by the search robot 120 is databased. Here, databaseization is performed by performing morphological analysis on predetermined information located on a website and creating an index table. 130 means a sequence of steps to store. The database 130 is for storing all website information collected by the search robot 120. Search engine software 140 functions to present search results to the user. The software searches numerous pages stored in the database 130 and lists the search results in order of accuracy matching the search terms. The conventional search engine as described above registers information about a website with a search engine in the following manner and provides the information to a user.

(1) As described above, predetermined information is collected using a search robot, and the collected information is registered by a professional surfer to register the website with a search engine.

(2) Select a directory classified according to the subject of the website to be registered, apply for the website registration with respect to the selected directory, and register the search engine after inspection by a professional surfer. Depending on the search engine, such a directory registration may provide a service that reduces a registration time and receives a predetermined registration fee.

The website registered in the search engine by the above method is searched and provided to the user according to various search methods such as integrated web search or directory search according to a user's search word input to search for predetermined information. The integrated web search is also called "search by word" in other terms. This search method stores a general purpose resource locator (URL) of all websites in a database and enters a specific keyword to find the desired information. Say. In addition, the directory search is also referred to as "search by topic" in another term, and this search method is classified by each field, and when a link is made to a desired field, a detailed search method of the field can be viewed. In this way, if the user continues to link and search for detailed items, the user can find the desired information. For example, if you want to find the scores of Korean teams in the 2002 Korea World Cup, you can search for Sports-> Ball-> Soccer-> World Cup-> Korea / Japan 2002 World Cup-> Korean Team score. You can do it. 1B is a screen showing an example of such a directory search method. As a directory searched for "World Cup", directories such as "World Cup", "2002 FIFA World Cup Korea Japan", "History of World Cup", etc. are output, and the user is most likely to locate the information he / she wants to search. Information retrieval can be performed by moving to. Representative search engines using the web integrated search method described above include a Lycos (http://lycos.cs.cmu.edu) search engine developed by Mike L. Moldin of Carnegie Mellon University. A typical search engine that uses is Yahoo (http://www.yahoo.com). Currently, many search engines provide a hybrid service that services the above-described search method together.

The above-described conventional method of registering a website with a search engine and a method of searching a registered website has the following problems.

As the number of Internet users increase, the number of users who want to search for predetermined information increases, and the types of information that they want to search for become many. As the number of users and types of information to be searched for increases, a search term with high frequency is generated, and the search word with high frequency (hereinafter referred to as "popular keyword") is inserted into a website in various ways. There is a problem in that information about a website (hereinafter, referred to as a "deception site") containing content which is completely useless is provided to a user who wants to search by using a search word. For example, if a user who wants to search for information on one of the popular keywords "Pikachu" enters "Pikachu" as a search term, all registered website information including "Pikachu" on the website is displayed. Among the websites, the content is about adult content, and there may be websites that insert "Pikachu" text in a variety of (mostly malicious) ways in the middle of the website. There is a problem that the information of the website is exposed to users of various ages due to the insertion of the above-mentioned popular keywords.

As a solution for solving the above-mentioned problems, it is necessary to continuously report the complaints of users or to monitor the registration website through a professional person such as a professional surfer. However, the solution according to the related art is the ultimate solution to the above-mentioned problems. It is obvious that this can not be done, and if a method capable of automatically performing such a problem through a predetermined algorithm on the Internet can be derived, it can be a useful means to solve the above-mentioned problems at once.

The method for managing the registration of a website in the search engine according to the present invention is to solve the above-described problems of the prior art, and the search engine can be automatically detected by using a predetermined algorithm for the deception site described above. It is an object of the present invention to provide a search engine that allows a user to search exactly the information he wants to search.

In addition, the method for managing the registration of the website in the search engine according to the present invention is to automatically detect the deceptive site, and to apply sanctions to the detected deception site operator of the website itself registered with the search engine. Its purpose is to enable midnight to be strengthened.

In addition, the method for managing the registration of the website in the search engine according to the present invention by allowing the sanctions, such as the detection of the deception site and the warning of the detected sites to be automatically performed by a predetermined algorithm, The goal is to save a large number of human resources that can be spent on site detection.

Hereinafter, a method for managing registration of a website in a search engine according to an exemplary embodiment of the present invention shown in FIG. 3 will be described with reference to FIGS. 4A to 4K and FIG. 6.

A method for managing registration of a website in a search engine according to an exemplary embodiment of the present invention shown in FIG. 3 is performed as follows. The registrant who wants to register a predetermined website in the search engine makes a website registration request together with information about the website that he / she wants to register (step 305). The information about the website is classified and recorded by information fields (registrant name, address, email address, mobile terminal number, etc.) in the website information database (step 310), and the website is registered in a search engine ( Step 315) This registration step (step 315) can be performed via several routes, as described above, a website administrator may register by requesting a search engine to register his website, In some cases, the website registrant itself may register the website's subject matter (eg, "Pikachu") by using the website information obtained by the robot randomly traversing the web. Apply for registration of the website in the category that most closely matches the subject of the website, and apply to the website. In the case of a web surfer, it can be registered in a search engine when it is determined that the predetermined conditions (website completion, noncommercial site requirements are met if the registration fee is not paid, etc.) are satisfied. In the method for managing the registration of the website in the search engine according to the description of the route registered in the search engine limited to the case by the registrant's application, but in the search engine according to the present invention to manage the registration of the website The method and the system can be equally applied to various other methods of registering a website with a search engine.

When the website is registered, the search engine controls the search robot to read the source file constituting the web page of the registered website and analyze the read source file (step 320).

An analysis method according to an embodiment of the present invention is a method of analyzing a HyperText Markup Language (HTML) document. More specifically, by analyzing the tags in the HTML document of the website, it is possible to determine whether or not the frequently occurring search terms, that is, the website that inserted the popular keyword into the HTML document that constitutes the website, or deception site. do. As those skilled in the art will appreciate, an HTML document is composed of a kind of command called a tag, and a web designer, such as a website creator, constructs a website through such a tag, and uses his or her web to display content that the website wants to provide. Include it on the site.

4A to 4K illustrate various implementations of analyzing a hypertext markup language document of a website, which is performed in operation 320 of FIG. 3A, by including a character string that may be determined as a deceptive site in a tag included in an HTML document. As examples showing, in more detail, various types of detection of deceptive sites in various manners by analyzing HTML document tags of a website. Hereinafter, with reference to Figs. 4A to 4K, how the analysis of the HTML document is performed in the method for managing the registration of the website in the search engine according to the present invention.

(1) Deception site using a string of the same color as the background color

4A is a diagram illustrating an example of a deceptive site that includes, as a tag, a string having the same color as the background color of the website. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. In the source file shown at the top of FIG. 4A, #FFFFFF is designated as the background color (bgcolor) and the color of the text is also designated as #FFFFFF, so that the texts "Starcraft" and "Zolaman" are displayed on the website. It becomes invisible to. The example shown at the bottom of FIG. 4A is similarly designated as #FFFFFF, which means white as the background color, and the color of the text is also designated as white, so that the texts "StarCraft" and "Zolaman" are displayed on the website. It will not be visible on the screen. The <body> tag shown in the source file of FIG. 4A allows a user to set various attributes of a background or text displayed in a web browser, as will be appreciated by those skilled in the art. The tag can be divided into a tag consisting of a start tag and an end tag (a <body> </ body> or <font> </ font> tag shown in FIG. 4A) and a single tag without the need for an end tag. You can use these tags to organize your website in a variety of ways. If the background color and the color of the text string are the same as described above, the website may be displayed on the search result screen even though the website includes content unrelated to the popular keyword by matching a predetermined popular keyword.

(2) Deception sites using strings included in the redirection page

4B is a diagram illustrating an example of a deception site using a character string included in a redirect page. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As will be appreciated by those skilled in the art, the redirection is for establishing a movement from the connected website to the new website, and may be implemented in the form of a source file shown on the right side of FIG. 4B. In the example using the meta tag on the top of the source file on the right, the http-equiv attribute is used. The meta tag is generally set to automatically move to another document after a predetermined time (the time specified in the content item of FIG. 4B). When the address of the homepage is changed, the meta tag is notified to a user who has accessed the old address. This function is used to show a and to automatically move to a new address after a predetermined time. In addition, in the case of the right middle side and the bottom side of FIG. 4B, the current web page is redirected to “http://www.naver.com” by using the self.location tag and the location.replace tag, respectively.

In the example of the deception site using the redirect page shown in FIG. 4B, the meta tag in the upper right is followed by the redirect command, and in the case of the interruption and the lower end, the </ script> tag is followed by a predetermined popular keyword (“Starcraft”, "Jola Man") is inserted.

In the case of such a redirect page, the tag itself is instructing the movement of another website. Therefore, the text added after the tag does not play any role. Instead, the search result of the search robot is based on the frequency of occurrence of the string in the website. As a result, the subject of the website may be judged differently from the original subject. Therefore, if the redirection page includes a string as described above, such a website may be displayed on the search result screen even though the website includes content unrelated to the popular keyword in response to the popular keyword.

(3) Deception site using character string using title tag

4C is a diagram illustrating an example of a deception site using a character string included in a title tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As the person skilled in the art will appreciate, the title tag is displayed on the top of the web browser. As a tag used to briefly display a subject, it may be implemented in the form of a source file shown on the right side of FIG. 4C. As an example of using the title tag on the upper side of the source file on the right side, the title tag includes a number of popular keywords such as "StarCraft" and "Zolaman", and the tag is output like the web browser on the left side. 4C, a plurality of title tags are used. The source file in the lower figure contains a number of popular keywords, such as "Hiddink," StarCraft "," Zolaman ", between the <title> and </ title> tags.

In the case of such a title tag, no matter how many strings are included in the title tag, it is not displayed in the web browser, whereas the search results of the search robot are determined by the frequency of occurrence of the strings in the website. Because of this, the subject of the website can be judged differently from the original subject. Therefore, if the length of the string included in the title tag is equal to or larger than a predetermined value or the number of the title tag is plural, even if such a website matches the popular keyword and contains content irrelevant to the popular keyword, The search result screen may be displayed.

(4) Deception site using character string included in meta tag

4D is a diagram illustrating an example of a deception site using a string included in a meta tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left.

As will be appreciated by those skilled in the art, the meta tag is used to express general information about an HTML document that is not displayed in the body of a web browser, such as the author, creation date, and keyword of the HTML document. Referring to the source file on the right side of FIG. 4D, the document name in the meta tag is description, and the content of the document includes many popular keywords such as "StarCraft" and "Zolaman". In this case, the string, such as the popular keyword included in the meta tag, is not displayed in the web browser, whereas the search result of the search robot is determined according to the frequency of occurrence of the string in the website. You can judge. Therefore, if the meta tag includes the character string as described above and the length of the character string is equal to or larger than a predetermined value, the website is displayed on the search result screen even though the website includes content that is not related to the popular keyword. Can be displayed.

(5) Deception site using string located in frame tag

4E is a diagram illustrating an example of a deception site using a string located in a frame tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As will be appreciated by those skilled in the art, a frame tag is used when a screen displayed on a web browser is to be divided into two or more. Referring to the right source file of FIG. 4E, the frame tag <FRAMESET ROWS = "") is a tag for dividing the screen horizontally, and the allocation information for dividing the screen is inserted in the "". The string placed after the end of the frame tag includes a number of popular keywords such as "Starcraft" and "Zolaman". In this case, the string that is the popular keyword or the like placed after the end tag of the frame tag has nothing to do with screen division of the web browser, whereas the search result of the search robot is determined according to the frequency of occurrence of the string in the website. You can judge the theme of your site differently from the original theme. Therefore, if the character string is placed in the frame tag as described above and the length of the character string is equal to or larger than a predetermined value, the website is displayed on the search result screen even though the website includes content irrelevant to the popular keyword. Can be.

(6) Deceptive sites using strings contained in form tags

FIG. 4F illustrates an example of a deception site using a string included in a form tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As will be appreciated by those skilled in the art, form tags are used to define a given form that is output to a web browser. Referring to the source file on the right side of FIG. 4F, the form tag may be configured in the form of "<form> <input type =" button type "value =" displayed characters "> </ form>. In the case of the source file shown in the figure, the button type is "hidden" so that no characters are displayed on the button, and the displayed characters, that is, the strings that are not actually displayed in the web browser, are "StarCraft" and "Zolaman". In this case, the popular keyword or the like contained in the form tag has nothing to do with defining the form of the web browser, while the search results of the search robot are displayed within the website. The subject of the website can be judged differently from the original subject, since it is determined according to the frequency of appearance. Even though the site may be pandering to popular keywords, including independent content and the most popular keywords, the search results display screen.

(7) Deception site using character string included in Div tag

4G illustrates an example of a deception site using a string included in a div tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As those skilled in the art will appreciate, div tags are typically used with style sheets using IDs and class attributes. Looking at the right source file of Figure 4G, the div tag is "<div style =" display: none; … In this case, since the style of the string output to the web browser is none, the subsequent string is not displayed in the web browser. In this case, it is included in the div tag. While the string, which is the popular keyword, has nothing to do with the screen display of the web browser, the search result of the search robot is determined according to the frequency of occurrence of the string in the website, so that the subject of the website can be judged differently from the original subject. Therefore, when the length of the string included in the div tag is equal to or greater than a predetermined value, the website may be displayed on the search result screen even though the website includes content that is not related to the popular keyword in response to the popular keyword. Can be.

(8) deceptive sites using strings contained in a href tags

4H is a diagram illustrating an example of a deception site using a string included in an a href tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left. As will be appreciated by those skilled in the art, the a href tag is used to link an address to a specific text or image within a document for easy navigation to another document or to another website. Referring to the source file on the right side of FIG. 4H, the a href tag may be configured in a format of "<a href="#move location or address"> link display target </a>". Referring to the source file shown on the right side of FIG. 4H, since a moving position and a link display target are not specified at all, the a href tag is a tag that is not displayed or executed on a web browser. Many of the popular keywords such as "StarCraft" and "Zolaman" are included in the string included in the tag that is not executed. In this case, the string, such as the popular keyword included in the a href tag, has nothing to do with the screen output or link execution of the web browser, while the search results of the search robot are determined according to the frequency of occurrence of the string in the website. You can judge the theme of the site differently from the original theme. Therefore, when the length of the string included in the a href tag is greater than or equal to the predetermined value as described above, the website may be displayed on the search result screen even though the website includes content that is not related to the popular keyword. There is a danger.

(9) Deception site using link farm

4I is a diagram illustrating an example of a deception site using a string included in an a href tag. As will be appreciated by those skilled in the art, a link farm is often used as a means to ultimately rank a web page by interlinking web pages within its website to allow a search robot to continue to search the website. Such a link farm may be implemented using the a href tag described above.

Websites using such link farms are difficult to determine directly as deceptive sites, but if the link farm is used excessively over a certain number, the search engine may use a method to continuously search popular keywords in the webpage. If you do this is likely to be a deception site, it needs to be detected.

(10) Deception site using the string contained in the font tag

4J illustrates an example of a deception site using a character string included in a font tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left.

As will be appreciated by those skilled in the art, the font tag is used to designate the size of a string displayed on a web browser, etc. The font size is set to 0 in the source file shown in FIG. 4J. Therefore, the strings included in these font tags are not displayed at all in the web browser. As such, when a string having a font size of 0 does not display a large number of popular keywords such as "StarCraft" and "Zolaman", the string such as the popular keyword included in the font tag is different from the screen output of the web browser. On the other hand, since the search result of the search robot is determined according to the frequency of occurrence of the character string in the website, the subject of the website can be judged differently from the original subject. Therefore, when the size of the character string included in the font tag is 0 as described above, the web site may be displayed on the search result screen despite the fact that the web site includes content unrelated to the popular keyword.

(11) deceptive sites using strings embedded in image tags

4K is a diagram illustrating an example of a deception site using a string included in an img tag. The figure on the left shows the screen of the website displayed to the user, and the figure on the right is the HTML source file of the website displayed on the left.

As will be appreciated by those skilled in the art, an img tag is used to insert a predetermined image into a document, and an image file to be inserted is designated as "a.gif" in the source file shown in FIG. 4K. In the img tag, an image to be inserted is designated, and then attributes such as the position and alignment method of the image are designated. In FIG. 4K, such an attribute is designated as a string. In this case, when the image is displayed on a web browser, an attribute designated as a string has no effect on the image display. When the strings that do not affect the attributes of the image include a number of popular keywords such as "Starcraft" and "Zolaman", the strings such as the popular keywords included in the img tag are different from the screen output of the web browser. On the other hand, since the search result of the search robot is determined according to the frequency of occurrence of the character string in the website, the subject of the website can be judged differently from the original subject. Therefore, when the length of the character string included in the img tag is greater than or equal to the predetermined value as described above, the website may be displayed on the search result screen even though the website includes content that is not related to the popular keyword. .

In operation 320, the tag and the like included in the HTML document are analyzed to measure the length of the character string described in the tag or the like as described above. Based on the measurement result, it is determined in step 325 whether the website is a deceptive site based on a predetermined criterion.

Examples of predetermined criteria for determining whether the website analyzed in step 325 is a deceptive site are as described above with reference to FIGS. 4A to 4K. For example, the predetermined criterion is whether the hypertext markup language document includes a character string having the same color as the background color of the web page, or the predetermined criterion is a redirection tag in the hypertext markup language document. It may be whether or not a string is included in the.

According to a preferred embodiment of the present invention, the predetermined criterion of step 325 is a deception in the case of exceeding the predetermined criterion by applying the analysis content described in the deception site types of (1) to (11) described above in a hybrid manner. You can use the method to determine the site. For example, since the number of title strings included in the title tag is two or more, 10 points are added per one and up to 70 points can be added. In addition, if there are character strings included in the redirection page, 70 points may be added regardless of the number, and in the case of a link farm, 4 points per 50 links may be added up to 80 points. In addition, if there is a character string of size 0, it can be set to add up to 70 points by adding 5 points for every 100 bytes of string length. As described above, when the source file constituting the web page is analyzed and the total calculated based on the points and the point weights according to the various criteria is more than 100 points, the corresponding website may be determined to be a deceptive site. In the case of using such a comprehensive judgment method, a judgment based on one type (e.g., a deception site because the number of strings included in the title tag is 50) is likely to be in error. It may be desirable to determine whether or not a deceptive site by comprehensively determining as described above.

In addition, according to a preferred embodiment of the present invention, the predetermined criteria may be differentially applied in the case of a website registered by a web search method by a search robot and a website registered by a predetermined directory designation method. For example, in the case of the website registered by the former method, if the source file analysis of the web page is found to be three of the 11 types described above, and judged as a deception site, the website is registered in the latter manner. In the case of one type, a method such as determining a deception site can be used. This is because in the latter registration method, since most search engine operators receive a predetermined registration fee from the registrant of the website, it is necessary to do some favor than the former one which is registered for free.

If it is determined in step 325 as a deceptive site, the website registrant field of the database means is searched to obtain registrant information of the website (step 330). The registrant's contact information is extracted from the registrant information of the website (step 335), and predetermined warning measures such as sending an e-mail or sending a short message are performed to the registrant of the website using the extracted contact information. (Step 340). Such warning measures will be described in detail with reference to FIG. 5 to be described later.

According to another embodiment of the present invention, what is analyzed in step 320 may be an image described in a tag. For example, when the pixels of an image are analyzed to extract RGB components constituting the pixels, and as a result of the extraction, pixels of a specific color (yellow, etc.) exceed a predetermined criterion (for example, 50% or more of the total number of pixels). In the meantime, it can be assumed that the site is posting the pornographic contents, and based on this, it can be determined whether the site is deceptive.

FIG. 5 is a flowchart illustrating a method for applying a predetermined sanction to a registrant of a website determined to be a deceptive or altered site in a method for managing registration of a website in a search engine according to an exemplary embodiment of the present invention. to be.

Referring to FIG. 5, the automatic sanction measures when the deception site is determined in step 325 of FIG. 3 described above are illustrated. If determined to be a deceptive site, the website management module searches the website information database to obtain the registrant information of the website (step 510), and the website management module receives the registrant information (step 520 and 550). According to an embodiment of the present invention, the website management module extracts contact information such as an e-mail address or a mobile communication terminal number of a registrant from the registrant information (step 530), and controls the contact information by controlling a mail server or an SMS server. To transmit the predetermined message to the client (step 540).

According to another embodiment of the present invention, the website management module extracts the registrant's other registered website information from the registrant information (step 560), and analyzes other websites registered under the same registrant name (step 570). ) To automatically execute. This is because a website in the same registrant's name is more likely to operate the deception site in the same or similar way. In the present embodiment, if it is determined that the analysis result of the other website is the deception site, step 510 of FIG. 5 may be repeated.

According to a preferred embodiment of the present invention, if a predetermined website is determined to be a deceptive site by the above-described analysis and determination method, the website is automatically sent to the registrant of the website by sending an e-mail, a short text message, or the like. It can act to point out the problem and to allow for a period of grace. In addition, the analysis and determination process may be automatically performed after a certain grace period has elapsed, and in this case, if the correction is not corrected, sanctions such as cancellation of registration may be taken. In addition, according to another embodiment of the present invention, the registrant of the website may be subject to sanctions such as to complicate the registration process in the case of registering another web page in the future.
