Description
METHOD FOR RECOMMENDING ADVERTISING KEYWORD BY INPUTTING URLAND SYSTEM THEREOF
Technical Field The present invention relates to a method and system for recommending an advertisement keyword using an input of a Universal Resource Locator (URL), and more particularly, to a method and system for recommending an advertisement keyword that can analyze an advertised site and recommend an advertisement keyword appropriate for the site when a URL of the advertised site is received from an advertiser.
Background Art
In a conventional advertising method using an advertisement keyword, an advertiser purchases an advertisement keyword associated with a site or a product that the advertiser desires to advertise. When the purchased advertisement keyword is retrieved, the advertiser can advertise the site or the product in association with search results. For example, when the advertiser desires to advertise product 'aaa' and the product 'aaa' is a portable device, the advertiser purchases the advertisement keyword 'portable device1. When the advertisement keyword 'portable device' is retrieved, the advertiser provides an advertisement of the product 'aaa' for a user who enters the advertisement keyword as a search keyword in association with search results of the advertisement keyword 'portable device'.
The conventional advertising method using a search keyword uses a keyword associated with a site or a product that the advertiser desires to advertise, or a keyword that is suggested at an advertised site. For example, when the advertiser advertises a site 'bbb1, the conventional advertising method using the search keyword may display an advertisement only for a user who knows the site 'bbb'. Specifically, the advertising method may advertise the advertisement only when the user selects the site 'bbb' as an advertisement keyword. Generally, a great advertising effect may be obtained when the site 'bbb' is exposed for users who do not know the site 'bbb'. Specifically, the conventional advertisement method may not provide an appropriate advertisement service when a user selects a wrong advertisement keyword.

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures. FIG. 1 is a diagram illustrating an interoperating relation between an advertiser terminal 110 and an advertisement keyword recommendation system 130 according to an exemplary embodiment of the present invention.
Referring to FIG. 1, when an advertiser desires an advertisement keyword appropriate for an advertised site that the advertiser desires to advertise, the advertiser terminal 110 receives from the advertiser a request for access to the advertisement keyword recommendation system 130. In response to the access request from the advertiser, the advertiser terminal 110 accesses the advertisement keyword recommendation system 130 via a communication network 120.
The communication network 120 may be either a wired communication network or a wireless communication network that transmits data between the advertiser terminal 110 and the advertisement keyword recommendation system 130.
When the advertiser terminal 110 is in an accessed state to the advertisement keyword recommendation system 130 and in this state, receives a Universal Resource
Locator (URL) of an advertised site that the advertiser desires to advertise, the advertiser terminal 110 transmits the URL to the advertisement keyword recommendation system 130 via the communication network 120.
The URL denotes a standard that indicates a location of each of various types of
information in the Internet. Generally, a web browser simultaneously supports various types of services in the Internet. For example, the web browser can simultaneously support services such as Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Usenet news, e-mail, Gopher, a telecommunication network, and the like. A location indication system is needed to obtain necessary information from a large number of servers that provide various types of services. For the above operation, the URL is used. The URL is used to indicate a location of each file included in each server, and includes a service type to be accessed, a server location, that is, a domain name, and a file location. A general URL syntax includes "protocolV/computer name including information/directory name/file name". As an example of the URL, "http://www.ebook.com/Main/default.aspx" may be used.
The advertisement keyword recommendation system 130 receives from the accessed advertiser terminal 110 the URL of the advertised site that is entered by the advertiser, via the communication network 120. The advertisement keyword recommendation system 130 searches for the advertised site corresponding to the received URL and analyzes a keyword included on a web page of the searched advertised site. Specifically, the advertisement keyword recommendation system 130 classifies a main keyword based on a total number of times that a particular keyword appears in the entire document set on a web page of the advertised site and a number of documents that include the particular keyword in the entire document set.
The advertisement keyword recommendation system 130 extracts a main keyword or an advertisement keyword based on the result of the analysis. Specifically, the advertisement keyword recommendation system 130 extracts as the main keyword or the advertisement keyword a term that is frequency used for searching based on the result of the analysis.
The advertisement keyword recommendation system 130 may search through the advertised site of the URL and extracts a biz-keyword from the advertised site. In this instance, the biz-keyword denotes a keyword that has been sold as the advertisement keyword or exposed for a keyword advertisement service at least once. The advertisement keyword denotes a search keyword that has been sold to the advertiser at least once, and thereby has been selected as a keyword when the advertiser
advertises the advertised site, or is generally used by a user that searches through the advertised site. Therefore, the advertisement keyword is stored and maintained in a database. Also, the advertisement keyword is selected from keywords that are registered by analyzing morphemes of keywords of a text on the web page of the advertised site and using the average of the analyzed morphemes.
The advertisement keyword recommendation system 130 determines an importance of a particular keyword based on a value that is obtained by multiplying a term frequency tf by an inverse document frequency idf. The term frequency tf denotes a total number of times that the particular keyword appears in the entire document set and an inverse document frequency idf denotes an inverse number to a document frequency df that denotes a number of documents that include the particular keyword in the entire document set. The main keyword is determined based on the total number of times that the particular keyword appears in the entire document set, the number of documents that include the particular keyword in the entire document, and a weight of each keyword. Also, the main keyword may be a keyword that is most frequently used as a search keyword among the extracted keywords from the entire document on the web page of the advertised site. [Equation 1] Main keyword = tfidf + inter- word relevance As described above, the term frequency tf denotes the total number of times that the particular keyword appears in the entire document set, the document frequency df denotes the number of documents that include the particular keyword in the entire document st, the inverse document frequency idf denotes the inverse number of the document frequency df, and an inter-word relevance denotes a weight of a keyword that has a relevance with another word.
For example, when keywords 'search' and 'directory' are included in the text, the advertisement keyword recommendation system 130 may determine the relevance between the keywords 'search' and 'directory' is relatively high and assign a weight to a representative keyword 'search'. The advertisement keyword recommendation system 130 determines main keywords and extracts the advertisement keyword from the selected main keywords. Specifically, the advertisement keyword recommendation system 130 analyzes
morphemes of main keywords included in the text and selects a keyword that is registered as the advertisement keyword.
The advertisement keyword recommendation system 130 analyzes the extracted advertisement keyword, and displays a recommendation advertisement keyword on the advertiser terminal 110 via the communication network 120 based on the result of the analysis. Specifically, the advertisement keyword recommendation system 130 classifies the main keyword and the advertisement keyword based on the result of the analysis, obtains the average of the main keyword and the advertisement keyword, determines the recommendation advertisement keyword based on the obtained average, and displays the determined recommendation advertisement keyword for the advertiser.
As described above, according to the present invention, the advertisement keyword recommendation system 130 may receive the URL of the advertised site that the advertiser desires to advertise, analyze keywords of the advertised site corresponding to the URL, retrieve an advertisement keyword appropriate for the advertised site, and recommend the advertisement keyword for the advertiser.
Also, according to the present invention, the advertisement keyword recommendation system 130 may extract keywords from the advertised site that the advertiser desires to advertise, analyze the keywords, and recommend an appropriate advertisement keyword for the advertiser based on the result of the analysis. Thus, according to the present invention, since a recommendation advertisement keyword is provided based on a result of analyzing keywords of an advertised site, an advertiser may more easily select an advertisement keyword capable of effectively advertising the advertised site.
FIG. 2 is a block diagram illustrating a configuration of an advertisement keyword recommendation system 130 according to an exemplary embodiment of the present invention.
Referring to FIGS. 1 and 2, the advertisement keyword recommendation system 130 includes an input module 210, an extractor 220, an analyzer 230, a display module 240, and a database 250. The input module 210 receives from an advertiser a URL of an advertised site that the advertiser desires to advertise. As an example, when the advertised site of the advertiser is an Internet bookstore site, and a URL of the Internet bookstore site is
"http://www.ebook.com/Main/default.aspx" will be described.
When the advertiser desires to receive from the advertisement keyword recommendation system 130 an advertisement keyword appropriate for advertising an e- book site, the advertiser may directly enter into the input module 210 of the advertisement keyword recommendation system 130
"http://www.ebook.com/Main/default.aspx" that is the URL of the Internet bookstore site. As described above, according to an aspect of the present invention, the advertisement keyword recommendation system 130 may directly receive URL information of the advertised site from the advertiser using the input module 210. Also, the input module 210 may receive from the advertiser terminal 110 the
URL of the advertised site entered by the advertiser, via the communication network 120. When the advertiser receives from the advertisement keyword recommendation system 130 the advertisement keyword appropriate for advertising the Internet bookstore site using the advertiser terminal 110, the advertiser may access the advertisement keyword recommendation system 130 via the communication network 120, using the advertiser terminal 110. In this instance, when the advertisement keyword recommendation system 130 requests the advertiser to enter the URL of the advertised site, the advertiser may enter the URL of the Internet bookstore site, that is, "http://www.ebook.com/Main/default.aspx" using the advertiser terminal 110. The advertiser terminal 110 transmits to the advertisement keyword recommendation system 130 URL information of the Internet bookstore site entered by the advertiser, via the communication network 120. According to another aspect of the present invention, the advertisement keyword recommendation system 130 may receive URL information of the advertised site from the advertiser terminal 110 via the communication network 120.
The extractor 220 extracts a keyword by searching through the web page of the advertised site corresponding to the entered URL. The result of the keyword extraction may include a keyword of an html page of the advertised site of the URL, a site title of the advertised site, an explanation, a search keyword, and the like. Specifically, the extractor 220 may search through the web page of the advertised site of the entered URL, analyze a text included in the searched web page, and extract a keyword based on the result of the text analysis by referring to the database 250. The
database 250 may store and maintain keyword dictionary data for extracting the keyword.
For example, the extractor 220 may search through the web page of the Internet bookstore site corresponding to the entered URL, analyze the text in the searched web page, and extract various keywords such as 'local, overseas, books, bestsellers, million sellers, authors, purchase, payment, cash, card1, and the like.
As another example, the extractor 220 may search through an advertised site of the entered URL, and extract from the advertised site a biz-keyword that has been sold as the advertisement keyword or exposed for a keyword advertisement service at least once, by referring to keyword sales information that is stored in the database 250.
The analyzer 230 analyzes the extracted keyword. Also, the analyzer 230 may classify the extracted keyword into a main keyword and an advertisement keyword.
The main keyword is based on a total number of times that a particular keyword appears in the entire document set on a web page of the advertised site, a number of documents that include the particular keyword in the entire document set, and a weight of each keyword. Also, the main keyword may be a keyword that is most frequently used as a search keyword among the extracted keywords from the entire document on the web page of the advertised site.
The analyzer 230 may analyze the total number of times that the particular keyword appears in the entire document set and the number of documents that include the particular keyword in the entire document set, and select the main keyword based on the result of the analysis.
The analyzer 230 may analyze morphemes of keywords included in the text of the web page of the advertised site, and select an advertisement keyword using the average of the analyzed morphemes. Also, the advertisement keyword denotes a search keyword that has been sold to the advertiser at least once, and thereby has been selected as a keyword when the advertiser advertises the advertised site, or is generally used by a user that searches through the advertised site. Therefore, the advertisement keyword may be stored and maintained in the database 250. The analyzer 230 assigns a weight to a keyword that has an inter-word relevance on the result of the analysis. Specifically, the analyzer 230 may classify as a representative keyword a keyword of which the inter-word relevance is greater than or
equal to a predetermined reference value based on the analyzed inter-word relevance and assign the weight.
For example, when keywords 'search' and 'directory' are included in the text of the web page of the advertised site, the analyzer 230 may determine the relevance between the keywords 'search' and 'directory' is relatively high, and assign the weigh to the representative keyword 'search'.
Also, the analyzer 230 may analyze morphemes of keywords included in the entire document set of the advertised site of the URL and select a keyword that is registered as the advertisement keyword. The display module 240 may display the recommendation advertisement keyword for the advertiser based on the result of the analysis. Specifically, when the main keyword and the advertisement keyword are selected based on the result of the analysis, and the recommendation advertisement keyword is determined based on the average of the selected main keyword and the advertisement keyword, the display module 240 may display the determined recommendation advertisement keyword for the advertiser.
When the average of the main keyword and the advertisement keyword is greater than a predetermined reference value, the display module 240 may determine a corresponding keyword as the recommendation advertisement keyword. Specifically, when more than a predetermined number of recommendation advertisement keywords are displayed for the advertiser, the advertiser may take great pains to determine which advertisement keyword to select. Therefore, the display module 240 may display only a predetermined number of recommendation advertisement keywords in order to prevent the above problem and improve the advertising effect. For example, when the reference value is '50' and the average of the main keyword or the advertisement keyword is '60', the display module 240 may determine as the recommendation advertisement keyword either the main keyword or the advertisement keyword.
As described above, according to the present invention, the advertisement keyword recommendation system 130 may select only a keyword greater than a predetermined reference value and determine the selected keyword as the recommendation advertisement keyword, instead of using both the main keyword and
the advertisement keyword.
Therefore, according to the present invention, when the advertiser enters the URL of the advertised site, the advertisement keyword recommendation system 130 may analyze the advertised site of the URL, extract keywords, analyze the extracted keywords, and recommend an optimal advertisement keyword for the advertiser.
Also, according to the present invention, an optimal recommendation advertisement keyword may be provided by analyzing keywords included in an advertised site of an advertiser. Therefore, the advertiser may more easily select an advertisement keyword capable of effectively advertising the advertised site. FIG. 3 is a flowchart illustrating a method of recommending an advertisement keyword according to an exemplary embodiment of the present invention.
