DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an overview of an advertisement providing method according to an embodiment of the present invention. The advertisement providing system 100 according to an exemplary embodiment of the present invention may provide the advertiser page 120 to the advertiser terminal 110 through the wired or wireless network or may provide the advertiser page 120 with various web pages 130, To the user terminals. Here, the advertiser page 120 may be one of various web pages 130, and the advertiser terminal 110 may be one of the plurality of user terminals. At this time, the keyword for the advertiser's advertisement can be sold through the advertiser page 120, and when the keyword is input through the search page among the various web pages 130, the advertisement providing system 100 can display the advertiser's advertisement To provide advertisements for the advertiser by exposing a link to the web page including the search results page of the various web pages 130 through the search result page.

In addition, the advertisement providing system 100 may sell keywords according to a certain rule to advertisers, or may sell keywords according to certain rules. For example, in a method of selling a keyword according to a certain rule, the advertisement providing system 100 maintains a plurality of keyword matching engines, and an advertiser selects a matching method between the keyword and a query input from the user, The keyword can be sold by a method of directly selecting the engine. Here, each of the plurality of keyword matching systems can confirm whether or not a keyword sold through different rules matches a user query. As another example, as a method of selling a keyword according to a certain rule, the advertisement providing system 100 may sell a character string composed of at least one word and at least one special character as a keyword, or sell keywords to the advertiser in advance can do.

2 is a flowchart showing an advertisement providing method in the first embodiment of the present invention. The advertisement providing method according to the first embodiment can be performed by the advertisement providing system according to the first embodiment. That is, FIG. 2 illustrates a process in which each step is performed through the advertisement providing system, thereby explaining the advertisement providing method.

In step S201, the advertisement providing system confirms the character string input by the advertiser. Here, the character string may have a form of a keyword composed of at least one word or a form composed of at least one word and at least one special character.

In step S202, the advertisement providing system identifies a keyword matching engine selected by the advertiser among a plurality of keyword matching engines that check whether or not matching is performed between strings by different rules. As described above, the plurality of keyword matching engines check whether or not the strings are matched according to different rules, and the advertiser can select a keyword matching engine to be applied to the keyword, that is, the string inputted in step S201 , The advertisement providing system can confirm the selected keyword matching engine. At this time, the keyword matching engine may be selected through the selection information by the advertiser, but may be automatically selected according to the type of the character string input by the advertiser. For example, the string "travel" and the string "travel *" have different forms.

The plurality of keyword matching engines may include at least one second character string including at least one word in a position corresponding to the special character for a first character string composed of at least one word and predetermined special characters, And a keyword matching engine for matching the first character string with the first character string. In this case, the position according to the special character may be determined based on at least one of the kind of the special character and the order between the word and the special character in the first character string.

For example, the first string " car * "consisting of the word " car" and the predetermined special character "* " In this case, the first keyword matching engine may match the first string "car *" with at least one of all the second strings starting with the word "car ". That is, all strings beginning with the word " car "such as" car heaven ", "car repairing place "," car rental " As another example, another first string "premiere car" may be matched with any string beginning with the word " used "and ending with the word" car ".

The above-described keyword matching engine describes only one keyword matching engine among the plurality of keyword matching engines, and the plurality of keyword matching engines is not limited to the above-described keyword matching engine. For example, other keyword matching engines may match the two strings only if the two strings entered are exactly the same. In this case, the string input from the advertiser may have the form of a keyword composed of at least one word.

As described above, in step S203, the advertisement providing system can confirm the keyword matching engine selected by the advertiser from among a plurality of keyword matching engines that check whether or not the strings are matched with each other.

In order to identify the keyword matching engine selected by the advertiser among the plurality of keyword matching engines, the advertisement providing system may include an advertiser page including a function for selecting at least one keyword matching engine among the plurality of keyword matching engines And the keyword matching engine selected from the advertiser can be confirmed through the function. For example, a page for selling a keyword may be provided as the advertiser page, information on each of a plurality of keyword matching engines may be provided to the advertiser page, and a function of selecting at least one of the plurality of keyword matching engines may be So that the advertiser can check information on a plurality of keyword matching engines and select a keyword matching engine suitable for the advertiser.

In step S203, the advertisement providing system stores the character string in association with the selected keyword matching engine. That is, by storing a character string inputted by an advertiser and a keyword matching engine selected by the advertiser in association with each other, it is possible to compare the inputted character string and a query inputted by the user with a rule according to the keyword matching engine.

In step S204, the advertisement providing system applies the query inputted by the user to each of the plurality of keyword matching engines to confirm the advertisement of the advertiser corresponding to the query. Here, each of the plurality of keyword matching engines determines whether to match the character string associated with each of the plurality of keyword matching engines and the query according to each rule, and the advertisement providing system determines whether the character string matches the query You can see the advertiser's ads. For example, the above-described first keyword matching engine can confirm that the query " car repair "and the string" car * "are matched with each other, and the advertisement providing system confirms the advertiser's advertisement . Here, the query may be a keyword input through a search page or the like among various web pages 130 described with reference to FIG.

Alternatively, the advertisement providing system may analyze a query inputted by a user to identify a keyword matching engine to which the query is applied among the plurality of keyword matching engines, and then, using the identified keyword matching engine, You can also see ads from. For a query that requires morphological analysis, such as "where the car is good at repairing ", the second string " car repair" And a keyword matching engine for matching the first character string "car repair * ", and may check the advertisement of the advertiser corresponding to the query through the confirmed keyword matching engine. In other words, the user may select a desired keyword matching engine among a plurality of keyword matching engines according to a predetermined rule such as a form of a query, rather than selecting only a desired keyword matching engine.

In step S205, the advertisement providing system provides the advertisement of the identified advertiser. That is, the advertisement providing system can confirm the advertisement of the advertiser corresponding to the query inputted through the search page or the like, sets a link to the web page corresponding to the advertisement of the advertiser on the search result page, And provides the advertisement of the identified advertiser to the user terminal of one user.

In addition, the advertisement providing system may check a keyword matching result for each of the plurality of keyword matching engines during a predetermined period, and may perform keyword matching using a page exposed to sell the keyword to the advertiser, The results can be exposed. That is, not only the description of the keyword matching engine but also various statistical data such as a keyword matching result for each keyword matching engine, for example, the number of keyword matching, the infiltration rate to the advertiser page according to a query of a matched user, So that the advertiser can select an appropriate keyword matching engine when the user proceeds with the keyword purchase.

3 is a block diagram for explaining an internal configuration of an advertisement providing system in the first embodiment of the present invention. 3, the advertisement providing system 300 according to the first embodiment includes a character string verification unit 301, a keyword matching engine verification unit 302, a character string storage unit 303, an advertisement verification unit 304, And an advertisement providing unit 305.

The string check unit 301 checks the character string input by the advertiser. Here, the character string may have a form of a keyword composed of at least one word or a form composed of at least one word and at least one special character.

The keyword matching engine verifying unit 302 identifies a keyword matching engine selected by the advertiser among a plurality of keyword matching engines that check whether or not the strings are matched with each other. As described above, the plurality of keyword matching engines check whether the strings are matched with each other according to different rules. The advertiser selects a keyword matching engine to be applied to the character string identified by the keyword string checking unit 301 And the keyword matching engine checking unit 302 can check the selected keyword matching engine. At this time, the keyword matching engine may be selected through the selection information by the advertiser, but may be automatically selected according to the type of the character string input by the advertiser. For example, the string "travel" and the string "travel *" have different forms, and the keyword matching engine checking unit 302 may automatically check the corresponding keyword matching engine according to these different types .

The plurality of keyword matching engines may include at least one second character string including at least one word in a position corresponding to the special character for a first character string composed of at least one word and predetermined special characters, And a keyword matching engine for matching the first character string with the first character string. In this case, the position according to the special character may be determined based on at least one of the kind of the special character and the order between the word and the special character in the first character string.

For example, the first string " car * "consisting of the word " car" and the predetermined special character "* " In this case, the first keyword matching engine may match the first string "car *" with at least one of all the second strings starting with the word "car ". That is, all strings beginning with the word " car "such as" car heaven ", "car repairing place "," car rental " As another example, another first string "premiere car" may be matched with any string beginning with the word " used "and ending with the word" car ".

The above-described keyword matching engine describes only one keyword matching engine among the plurality of keyword matching engines, and the plurality of keyword matching engines is not limited to the above-described keyword matching engine. For example, other keyword matching engines may match the two strings only if the two strings entered are exactly the same. In this case, the string input from the advertiser may have the form of a keyword composed of at least one word.

In this manner, the keyword matching engine checking unit 302 can check the keyword matching engine selected by the advertiser from among a plurality of keyword matching engines that check whether or not the strings match each other with different rules.

The character string storage unit 303 stores the character string in association with the selected keyword matching engine. That is, by storing a character string inputted by an advertiser and a keyword matching engine selected by the advertiser in association with each other, it is possible to compare the inputted character string and a query inputted by the user with a rule according to the keyword matching engine.

The advertisement verification unit 304 applies the query inputted by the user to each of the plurality of keyword matching engines to confirm the advertisement of the advertiser corresponding to the query. At this time, each of the plurality of keyword matching engines determines whether to match the character string associated with each of the plurality of keyword matching engines and the query according to each rule, and the advertisement checking unit 304 determines a character string matching the query You can see the advertiser's ads through. For example, the first keyword matching engine described above can confirm that the query " car repair "and the string" car * "match with each other, and the advertisement confirmation unit 304 confirms that the advertiser's advertisement . Here, the query may be a keyword input through a search page or the like among various web pages 130 described with reference to FIG.

Alternatively, the advertisement verification unit 304 may analyze the query inputted by the user to identify a keyword matching engine to which the query is applied among the plurality of keyword matching engines, You can also see the advertiser's ads. For a query requiring morphological analysis such as "a car repairing place ", for example, for the first character string" car repair "inputted from the advertiser in the advertisement confirmation unit 304, 2 string and the first character string "car repair ", and confirms the advertisement of the advertiser corresponding to the query through the confirmed keyword matching engine. In other words, the user may select a desired keyword matching engine among a plurality of keyword matching engines according to a predetermined rule such as a form of a query, rather than selecting only a desired keyword matching engine.

The advertisement providing unit 305 provides the advertisement of the identified advertiser. That is, the advertisement providing unit 305 can confirm the advertisement of the advertiser corresponding to the query inputted through the search page or the like, sets a link to the web page corresponding to the advertiser's advertisement on the search result page, To the user terminal of the input user, thereby providing the advertisement of the verified advertiser.

4 is an example of providing advertisements using a plurality of keyword matching engines. Here, the first dotted box 410 indicates a plurality of advertisers. In this case, for example, the first advertiser 411, the second advertiser 412, and the third advertiser 413 may receive the "first keyword + third keyword matching engine (method) (Method) "and a" first keyword + first keyword matching engine (method) "are input and selected, a keyword matching engine (method) The first advertiser 411 and the third advertiser 413 input the same keyword but use different keyword matching engines so that the query can not be performed The second dashed line box 420 represents a plurality of keyword matching engines. For example, the first keyword matching engine 421, the second keyword matching engine 421, 422) and the third keyword matching When a query is input by the user, the engine 423 can confirm whether or not matching between the keywords corresponding to the respective keywords and the query is performed according to each rule, and the first keyword matching engine 421, The second keyword matching engine 422 and the third keyword matching engine 423 use different rules.

As described above, by using the advertisement providing method or the advertisement providing system according to the first embodiment of the present invention, whether or not matching between the character string input by the advertiser and the keyword input by the user is performed by the advertiser among the plurality of keyword matching engines By using the selected keyword matching engine, it is possible to provide the advertisement of the advertiser by using various matching methods.

5 is a flowchart showing an advertisement providing method in a second embodiment of the present invention. The advertisement providing method according to the second embodiment can be performed through the advertisement providing system according to the second embodiment. 5, the advertisement providing method will be described by explaining the steps of performing the respective steps through the advertisement providing system.

In step S501, the advertisement providing system identifies a first character string composed of at least one word entered by the advertiser and at least one special character. The meaning of the special character may be predetermined for each category and for each order of the words, and the advertiser may construct and input the first character string in a desired meaning according to a predetermined meaning. At this time, the advertisement providing system can confirm the first character string inputted as described above.

In step S502, the advertisement providing system confirms the second character string including the word in the position according to the special character. Here, the position according to the special character may be determined based on at least one of the type of the special character and the order between the word and the special character in the first character string.

At this time, if the second character string starts with a word positioned before the special character of the first character string, the advertisement providing system can confirm that the second character string includes the word at a position corresponding to the special character. For example, a second string such as " computer A / S ", "computer sale" or the like starting with the word "computer " Can be confirmed.

Alternatively, the advertisement providing system may be configured such that when the second character string starts with a word positioned in front of a special character of the first character string and ends with a word positioned after the special character, . For example, for the first string "100 days * recommendation" consisting of the word "100 days ", the word" 100 day gift recommendation ", "100 day travel recommendation ", and the like.

In this manner, the advertisement providing system determines whether or not the corresponding word exists in a position corresponding to a special character determined based on at least one of the type of the special character and the order between the word and the special character in the first character string according to a predetermined rule The second character string can be confirmed.

In step S503, the advertisement providing system stores the second character string as a keyword for the advertisement of the advertiser. That is, by storing the second character string as a keyword for the advertisement of the advertiser in the advertisement providing system, the advertiser can input only the first character string and register the second character string associated with the first character string as keywords.

In step S504, the advertisement providing system provides the advertisement of the advertiser when the keyword is input by the user. In other words, since the keywords corresponding to the second character string are registered for the advertisement of the advertiser, the advertisement providing system can provide the advertisement of the advertiser when the keyword is inputted by the user. In this case, the advertisement providing system checks an advertisement of an advertiser corresponding to a keyword input through a search page or the like, sets a link to a web page corresponding to the advertisement of the advertiser on a search result page, And provides the advertisement of the identified advertiser to the user terminal of the user.

6 is a block diagram for explaining an internal configuration of an advertisement providing system in a second embodiment of the present invention. 6, the advertisement providing system 600 according to the second embodiment includes a first character string verification unit 601, a second character string verification unit 602, a keyword storage unit 603, and an advertisement provider 604 ).

The first character string verification unit 601 identifies a first character string composed of at least one word and at least one special character input by the advertiser. The meaning of the special character may be predetermined for each category and for each order of the words, and the advertiser may construct and input the first character string in a desired meaning according to a predetermined meaning. At this time, the first character string verification unit 601 can recognize the first character string input as described above.

The second character string verification unit 602 identifies a second character string including the word at a position corresponding to the special character. Here, the position according to the special character may be determined based on at least one of the type of the special character and the order between the word and the special character in the first character string.

At this time, if the second character string starts with a word positioned before the special character of the first character string, the second character string checking unit 602 can confirm that the second character string includes the word at a position corresponding to the special character. For example, a second string such as " computer A / S ", "computer sale" or the like starting with the word "computer " Can be confirmed.

Alternatively, the second character string checking unit 602 may determine whether the second character string is a character string that starts with a word positioned in front of the special character of the first character string and ends with a word positioned after the special character, It can be confirmed that the word is included. For example, for the first string "100 days * recommendation" consisting of the word "100 days ", the word" 100 day gift recommendation ", "100 day travel recommendation ", and the like.

As described above, the second character string checking unit 602 determines whether or not the character string corresponding to the special character is located at the position corresponding to the special character determined based on at least one of the kind of the special character and the order between the word and the special character in the first character string The second character string can be identified based on whether a word exists or not.

The keyword storage unit 603 stores the second character string as a keyword for the advertisement of the advertiser. That is, by storing the second character string as a keyword for the advertisement of the advertiser in the keyword storage unit 603, the advertiser can input only the first character string and register the second character string associated with the first character string as keywords .

The advertisement providing unit 604 provides the advertisement of the advertiser when the keyword is input by the user. In other words, since keywords corresponding to the second character string are registered for the advertisement of the advertiser, the advertisement providing unit 604 can provide the advertisement of the advertiser when the keyword is inputted by the user. In this case, the advertisement providing unit 604 confirms the advertisement of the advertiser corresponding to the keyword inputted through the search page or the like, sets a link to the web page corresponding to the advertiser's advertisement on the search result page, To the user terminal of the input user, thereby providing the advertisement of the verified advertiser.

FIG. 7 shows an example of expanding a keyword through a character string input from an advertiser. The advertisement providing system according to the second embodiment can be applied to a character string "pension "," reservation for pension ", "way to pension ", etc. starting with the word" pension " The second character string may be stored as a keyword for an advertisement of the advertiser who has input the first character string "Pension * ". When a keyword "way to pension" is input by the user, a link to a web page including the advertiser's advertisement may be set in a search result for the keyword " way to pension &

As described above, when the advertisement providing method or the advertisement providing system according to the second embodiment of the present invention is used, a second character string corresponding to the rule is checked through a first character string inputted by an advertiser according to a certain rule, It can be automatically expanded and sold.

8 is a flowchart showing an advertisement providing method in a third embodiment of the present invention. The advertisement providing method according to the third embodiment can be performed through the advertisement providing system according to the third embodiment. FIG. 8 illustrates a process of performing each step through the advertisement providing system, thereby explaining the advertisement providing method.

In step S801, the advertisement providing system identifies a first character string composed of at least one word input by the advertiser and at least one special character. The meaning of the special character may be predetermined for each category and for each order of the words, and the advertiser may construct and input the first character string in a desired meaning according to a predetermined meaning. At this time, the advertisement providing system can confirm the first character string inputted as described above.

In step S802, the advertisement providing system performs step S803 if the second character string inputted by the user confirms whether the second character string is included in the position according to the special character. Here, the position according to the special character may be determined based on at least one of the type of the special character and the order between the word and the special character in the first character string.

At this time, if the second character string starts with a word positioned before the special character of the first character string, the advertisement providing system can confirm that the second character string includes the word at a position corresponding to the special character. For example, if the second character string " computer repair "entered by the user includes the word" computer " included in the first string "computer * " &Quot;, it is possible to perform step S803.

Alternatively, the advertisement providing system may be configured such that when the second character string starts with a word positioned in front of a special character of the first character string and ends with a word positioned after the special character, . For example, when the second string "100 days travel recommendation" entered by the user is included in the first character string "100 days * recommended" composed of the words "100 days ", word" If it is confirmed that the word "100 days" and the word "recommendation" are included in the position according to the special character "* ", step S803 may be performed.

In step S803, the advertisement providing system confirms the advertisement of the advertiser. That is, when the second character string input by the user in step S802 confirms whether or not the word is included in the position according to the special character, the advertisement providing system determines that the first character string and the second character string Are matched with each other, and the advertisement of the advertiser who has input the first character string can be confirmed. In this way, the advertisement providing system can confirm the advertiser's advertisement according to the second character string by checking whether the first character string inputted according to the predetermined rule matches the second character string inputted by the user.

In step S804, the advertisement providing system provides the advertisement of the identified advertiser. That is, the advertisement providing system checks an advertisement of an advertiser corresponding to the second string, which is a keyword input through a search page, and sets a link to a web page corresponding to the advertisement of the advertiser on a search result page, And providing the second string to the user terminal of the input user, thereby providing the advertisement of the verified advertiser.

9 is a block diagram for explaining an internal configuration of an advertisement providing system in a third embodiment of the present invention. The advertisement providing system 900 according to the third embodiment of the present invention includes a first character string checking unit 901, an advertisement checking unit 902 and an advertisement providing unit 903 as shown in FIG.

The first character string verification unit 901 identifies a first character string composed of at least one word input by the advertiser and at least one special character. The meaning of the special character may be predetermined for each category and for each order of the words, and the advertiser may construct and input the first character string in a desired meaning according to a predetermined meaning. At this time, the first character string verification unit 901 can recognize the first character string input as described above.

The advertisement confirmation unit 902 confirms the advertisement of the advertiser when the second character string input by the user is confirmed to include the word at the position corresponding to the special character. Here, the position according to the special character may be determined based on at least one of the type of the special character and the order between the word and the special character in the first character string.

At this time, if the second character string starts with a word positioned before the special character of the first character string, the advertisement verification unit 902 can confirm that the word is included in a position corresponding to the special character.
