2 is a flowchart illustrating an advertisement providing method according to a first embodiment of the present invention. The advertisement providing method according to the first embodiment may be performed by the advertisement providing system according to the first embodiment. That is, FIG. 2 describes the advertisement providing method by describing a process in which each step is performed through the advertisement providing system.

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

In step S202, the advertisement providing system checks a keyword matching engine selected by the advertiser from among a plurality of keyword matching engines for checking the matching between character strings according to different rules. As described above, the plurality of keyword matching engines check whether the strings are matched according to different rules, and the advertiser may select a keyword, that is, a keyword matching engine to be applied to the string input in step S201. The advertisement providing system may identify the selected keyword matching engine. In this case, 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 corresponding keyword matching engine may be automatically selected by the advertisement providing system according to the different forms.

Here, the plurality of keyword matching engines may include at least one second string including the at least one word at a position corresponding to the special character with respect to a first string including at least one word and a predetermined special character. It may include a keyword matching engine to match the first string. In this case, a position according to the special character may be determined based on at least one of a type of the special character and an order between the word and the special character in the first string.

For example, the first string "car *" consisting of the word "car" and the predetermined special character "*" may mean all strings starting with the word "car". In this case, the first keyword matching engine may match the first string "car *" with at least one of all second strings starting with the word "car". That is, all strings starting with the word "car" such as "car heaven", "car repair place" and "car rental" may match the first string "car *". As another example, another first string "used * car" may match all strings that begin with the word "used" and end with the word "car".

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

As such, in operation S203, the advertisement providing system may identify a keyword matching engine selected by the advertiser from among a plurality of keyword matching engines for checking the matching between character strings according to different rules.

In step S203, the advertisement providing system stores the string in association with the selected keyword matching engine. That is, by storing the string input by the advertiser and the keyword matching engine selected by the advertiser in association with each other, the input string and the query input by the user can be compared with a rule according to the corresponding keyword matching engine.

In operation S204, the advertisement providing system confirms an advertisement of an advertiser corresponding to the query by applying a query input by a user to each of the plurality of keyword matching engines. In this case, each of the plurality of keyword matching engines determines whether to match the strings associated with each of the plurality of keyword matching engines and the query according to a respective rule, and the advertisement providing system corresponds to the corresponding string through the string matching the query. You can check the advertiser's advertisement. For example, the above-described first keyword matching engine may confirm that the query "car repair" and the string "car *" match each other, and the advertisement providing system checks an advertisement of an advertiser who inputs the string "car *". Can be. Here, the query may mean a keyword input through a search page or the like among the various web pages 130 described with reference to FIG. 1.

Alternatively, the advertisement providing system analyzes a query input by a user, identifies a keyword matching engine to which the query is applied, among the plurality of keyword matching engines, and uses the identified keyword matching engine to determine an advertisement corresponding to the query. You may also want to check your ad. For example, for a query requiring stemming, such as "where to repair a car", a second string beginning with "car repair" for the first string "car repair *" input from an advertiser in the advertisement providing system. And a keyword matching engine for matching the first string “car repair *” and an advertisement of an advertiser corresponding to the query may be checked through the identified keyword matching engine. In other words, not only an advertiser selects a desired keyword matching engine but also a user may select a desired keyword matching engine among a plurality of keyword matching engines according to a predetermined rule such as a query form.

In step S205, the advertisement providing system provides an advertisement of the identified advertiser. That is, the advertisement providing system may check an advertisement of an advertiser corresponding to a query input through the search page, and input the query by setting a link to a web page corresponding to the advertisement of the advertiser on a search result page. By providing to the user terminal of one user, it is possible to provide the advertisement of the identified advertiser.

3 is a block diagram illustrating an internal configuration of an advertisement providing system according to a first embodiment of the present invention. As shown in FIG. 3, the advertisement providing system 300 according to the first exemplary embodiment may include a string verification unit 301, a keyword matching engine verification unit 302, a string storage unit 303, and an advertisement verification unit 304. And an advertisement provider 305.

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

The keyword matching engine checking unit 302 checks the keyword matching engine selected by the advertiser among a plurality of keyword matching engines for checking the matching between character strings according to different rules. As described above, the plurality of keyword matching engines check whether the strings are matched according to different rules, and the advertiser selects a keyword, that is, a keyword matching engine to be applied to the strings checked by the string identification unit 301. The keyword matching engine checker 302 may check the selected keyword matching engine. In this case, 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 “trip” and the string “trip *” may have different forms, and the keyword matching engine checker 302 may automatically select a corresponding keyword matching engine according to the different forms. .

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

For example, the first string "car *" consisting of the word "car" and the predetermined special character "*" may mean all strings starting with the word "car". In this case, the first keyword matching engine may match the first string "car *" with at least one of all second strings starting with the word "car". That is, all strings starting with the word "car" such as "car heaven", "car repair place" and "car rental" may match the first string "car *". As another example, another first string "used * car" may match all strings that begin with the word "used" and end with the word "car".

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

As such, the keyword matching engine checker 302 may check the keyword matching engine selected by the advertiser from among a plurality of keyword matching engines for checking the matching between character strings according to different rules.

The string storage unit 303 stores the string in association with the selected keyword matching engine. That is, by storing the string input by the advertiser and the keyword matching engine selected by the advertiser in association with each other, the input string and the query input by the user can be compared with a rule according to the corresponding keyword matching engine.

The advertisement checking unit 304 applies a query input by a user to each of the plurality of keyword matching engines to identify an advertisement of an advertiser corresponding to the query. In this case, each of the plurality of keyword matching engines determines whether to match the strings associated with each of the plurality of keyword matching engines and the query according to a rule, and the advertisement verification unit 304 strings matching the query. You can check the advertisement of the advertiser. For example, the above-described first keyword matching engine may confirm that the query "car repair" and the string "car *" match each other, and the advertisement checking unit 304 may input the advertisement of the advertiser who inputs the string "car *". You can check. Here, the query may mean a keyword input through a search page or the like among the various web pages 130 described with reference to FIG. 1.

In addition, the advertisement verification unit 304 analyzes a query input by a user to identify a keyword matching engine to which the query is applied among the plurality of keyword matching engines, and corresponds to the query using the identified keyword matching engine. You can also check your ad. For example, for a query requiring stemming, such as "where to repair a car", the term "car repair *" for the first string "car repair *" input from an advertiser in the advertisement verification unit 304 is used. The keyword matching engine matching the second string with the first string "car repair *" may be checked, and the advertisement of the advertiser corresponding to the query may be checked through the identified keyword matching engine. In other words, not only an advertiser selects a desired keyword matching engine but also a user may select a desired keyword matching engine among a plurality of keyword matching engines according to a predetermined rule such as a query form.

The advertisement provider 305 provides the identified advertiser's advertisement. That is, the advertisement providing unit 305 may check the advertisement of the advertiser corresponding to the query entered through the search page, etc., and set the link to the web page corresponding to the advertisement of the advertiser on the search result page to set the query. By providing the to the user terminal of the user inputted, it is possible to provide the advertisement of the confirmed advertiser.

4 illustrates an example of providing an advertisement using a plurality of keyword matching engines. Here, the first dotted line box 410 represents a plurality of advertisers. In this case, as an example, the first advertiser 411, the second advertiser 412, and the third advertiser 413 are each referred to as “a first keyword + a third keyword matching engine (method), and a“ second keyword + third keyword matching engine ”. (Method) " and " first keyword + first keyword matching engine (method) ", the selected keyword matching engine (method) as well as the keyword that is the string entered by the advertiser for the same query entered by the user For example, the first advertiser 411 and the third advertiser 413 input the same keyword, but use different keyword matching engines (methods). The second dotted line box 420 indicates a plurality of keyword matching engines, for example, the first keyword matching engine 421 and the second keyword matching engine ( 422) and third keyword matching When a query is input by a user, the engine 423 may check whether keywords corresponding to each query match the query according to each rule, and the first keyword matching engine 421 and the second keyword matching engine may be used. Since different rules are used between 422 and the third keyword matching engine 423, matching may be different for the same keyword.

As such, when the advertisement providing method or the advertisement providing system according to the first embodiment of the present invention is used, it is determined by the advertiser among a plurality of keyword matching engines whether or not a match between a character string input by the advertiser and a keyword input by the user is performed. By using the selected keyword matching engine, the advertisement of the advertiser may be provided using various matching methods.

5 is a flowchart illustrating a method for providing an advertisement in a second embodiment of the present invention. The advertisement providing method according to the second embodiment may be performed through the advertisement providing system according to the second embodiment. In FIG. 5, the advertisement providing method will be described by describing a process in which each step is performed through the advertisement providing system.

In step S501, the advertisement providing system checks a first string composed of at least one word and at least one special character input by an advertiser. The special characters may be pre-determined by type and in the order of the words, and the advertiser may configure and input the first character string in a desired meaning according to the predetermined meaning. In this case, the advertisement providing system may check the first string input as described above.

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

In this case, the advertisement providing system may determine that the word includes the word at a position corresponding to the special character when the second string begins with a word located before the special character of the first string. For example, for a first string "computer *" consisting of the word "computer" and the special character "*", a second string such as "computer A / S", "selling computer", etc., beginning with the word "computer" You can check it.

Alternatively, the advertisement providing system includes the word at a position according to the special character when the second string starts with a word located before the special character of the first string and ends with a word located after the special character. It can be confirmed that. For example, for a first string "100 days * recommendation" consisting of the word "100 days", the word "recommendation" and the special character "*", the word "100 days" and the word "recommendation" A second string such as "100-day gift recommendation" and "100-day travel recommendation".

As described above, the advertisement providing system determines whether the word exists at a position according to the special character determined based on a type of the special character and at least one of the order of the word and the special character in the first character string according to a predetermined rule. According to the second string can be confirmed.

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

In operation S504, when the keyword is input by the user, the advertisement providing system provides an advertisement of the advertiser. In other words, since keywords corresponding to the second string are registered for the advertisement of the advertiser, the advertisement providing system may provide the advertisement of the advertiser when the keyword is input by the user. In this case, the advertisement providing system checks an advertisement of an advertiser corresponding to a keyword entered through a search page, etc., sets a link to a web page corresponding to the advertisement of the advertiser on a search result page, and inputs the keyword. By providing the user terminal of the user, it is possible to provide the advertisement of the confirmed advertiser.

6 is a block diagram illustrating an internal configuration of an advertisement providing system according to a second embodiment of the present invention. As shown in FIG. 6, the advertisement providing system 600 according to the second embodiment includes a first string checking unit 601, a second string checking unit 602, a keyword storage unit 603, and an advertisement providing unit 604. ).

The first string checking unit 601 verifies a first string composed of at least one word and at least one special character input by the advertiser. The special characters may be pre-determined by type and in the order of the words, and the advertiser may configure and input the first character string in a desired meaning according to the predetermined meaning. In this case, the first string checking unit 601 may check the first string input as described above.

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

In this case, when the second string begins with a word located before the special character of the first string, the second string checking unit 602 may confirm that the word is included in the position corresponding to the special character. For example, for a first string "computer *" consisting of the word "computer" and the special character "*", a second string such as "computer A / S", "selling computer", etc., beginning with the word "computer" You can check it.

Alternatively, if the second string is started with a word located before the special character of the first string and ends with a word located after the special character, the second string checking unit 602 may be located at a position according to the special character. It can be confirmed by including the word. For example, for a first string "100 days * recommendation" consisting of the word "100 days", the word "recommendation" and the special character "*", the word "100 days" and the word "recommendation" A second string such as "100-day gift recommendation" and "100-day travel recommendation".

As such, the second character string checking unit 602 corresponds to a position according to a special character determined based on a type of special character and at least one of an order of the word and the special character in the first string according to a predetermined rule. The second string may be checked according to whether a word exists.

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

The advertisement providing unit 604 provides an advertisement of the advertiser when the keyword is input by the user. In other words, since keywords corresponding to the second string are registered with respect to the advertisement of the advertiser, the advertisement providing unit 604 may provide the advertisement of the advertiser when the keyword is input by the user. In this case, the advertisement providing unit 604 checks the advertisement of the advertiser corresponding to the keyword entered through the search page, etc., and sets a link to the web page corresponding to the advertisement of the advertiser on the search result page to set the keyword. By providing the input to the user terminal of the user, it is possible to provide the advertisement of the identified advertiser.

7 is an example of expanding a keyword through a string input from an advertiser. According to the second exemplary embodiment, the advertisement providing system includes a string "pension", "pension reservation", "way to pension", etc. starting with the word "pension" as in the dotted box 702 for the first string "pension *". The second string may be stored as a keyword for the advertisement of the advertiser who inputs the first string “Pension *”. Thereafter, when the keyword “the way to the pension” is input by the user, a link to a web page including the advertisement of the advertiser may be set in the search result for the keyword “the way to the 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, the second string corresponding to the rule is identified as a keyword through the first string input by the advertiser according to the predetermined rule. It can be automatically extended and sold.

8 is a flowchart illustrating an advertisement providing method according to a third embodiment of the present invention. The advertisement providing method according to the third embodiment may be performed through the advertisement providing system according to the third embodiment. 8 illustrates the advertisement providing method by describing a process in which each step is performed through the advertisement providing system.

In step S801, the advertisement providing system checks a first string composed of at least one word and at least one special character input by an advertiser. The special characters may be pre-determined by type and in the order of the words, and the advertiser may configure and input the first character string in a desired meaning according to the predetermined meaning. In this case, the advertisement providing system may check the first string input as described above.

In step S802, the advertisement providing system checks whether or not the second string input by the user includes the word in a position according to the special character, and performs step S803. The position according to the special character may be determined based on at least one of a type of the special character and an order between the word and the special character in the first string.

In this case, the advertisement providing system may determine that the word includes the word at a position corresponding to the special character when the second string begins with a word located before the special character of the first string. For example, the word "computer" contained in the first string "computer *" composed of the word "computer" and the special character "*" is entered by the user. If it is determined whether to include in the position according to "in", step S803 may be performed.

Alternatively, the advertisement providing system includes the word at a position according to the special character when the second string starts with a word located before the special character of the first string and ends with a word located after the special character. It can be confirmed that. For example, the second string "100 days recommendation" entered by the user is included in the first string "100 days * recommendation" consisting of the word "100 days", the word "recommendation", and the special character "*". When the word "100 days" and the word "recommendation" are included in the position according to the special character "*", the step S803 may be performed.

In step S803, the advertisement providing system checks the advertisement of the advertiser. In other words, when the second string input by the user in step S802 includes checking whether the word is included in the position according to the special character, the advertisement providing system may include the first string and the second string. It can be determined that the match with each other, it is possible to check the advertisement of the advertiser input the first string. As such, the advertisement providing system may check the advertisement of the advertiser according to the second string by checking whether the first string input by the user and the second string input by the user is matched according to a predetermined rule.

In step S804, the advertisement providing system provides an 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. By providing the second character string to the user terminal of the user who inputs the advertisement, the identified advertiser may be provided.

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

The first string checking unit 901 verifies a first string composed of at least one word and at least one special character input by the advertiser. The special characters may be pre-determined by type and in the order of the words, and the advertiser may configure and input the first character string in a desired meaning according to the predetermined meaning. In this case, the first string checking unit 901 may check the first string input as described above.

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

In this case, when the second string begins with a word located before the special character of the first string, the advertisement confirming unit 902 may confirm that the word is included in the position corresponding to the special character. For example, the word "computer" contained in the first string "computer *" composed of the word "computer" and the special character "*" is entered by the user. In the case of including and checking whether the information is included in the position according to ", the advertisement of the advertiser who inputs the first string" computer * "as a search result for the second string" computer repair "may be checked.

Alternatively, the advertisement checking unit 902, if the second string begins with a word located before the special character of the first string, and ends with a word located after the special character, the word is placed at the position according to the special character. It can confirm by including. For example, the second string "100 days recommendation" entered by the user is included in the first string "100 days * recommendation" consisting of the word "100 days", the word "recommendation", and the special character "*". In the case where the word "100 days" and the word "recommendation" are included in the position according to the special character "*", the first string "as a search result for the second string" 100-day destination recommendation "is included. Advertisers who entered "100 days * Recommendation" can be checked.

That is, when the second string input by the user includes checking and including the word in a position according to the special character, the advertisement checking unit 902 matches the first string with the second string. It may be determined, and the advertisement of the advertiser who inputs the first string may be checked. As such, the advertisement checking unit 902 may check an advertisement of the advertiser according to the second string by checking whether the first string input according to the predetermined rule matches the second string input by the user.

The advertisement providing unit 903 provides an advertisement of the identified advertiser. That is, the advertisement providing unit 903 checks the advertisement of the advertiser corresponding to the second string which is the keyword input through the search page and the like, and links the web page corresponding to the advertisement of the advertiser to the search result page. By setting and providing the second string to a user terminal of the user who inputs the second string, the advertisement of the identified advertiser may be provided.

FIG. 10 is a first string "pension * (recommend | cheap)" 1001 input from an advertiser and a second string "pension recommendation" 1002 input from a user in the advertisement providing system 900 described with reference to FIG. 9. , "Pension Cheaper" (1003), and "Road to Pension" (1004) is an example of checking whether or not matching. Here, the first string "pension * (recommend | cheap place" "may mean a string that starts with the word" pension "and ends with the word" recommendation "or the word" cheap place ". In this case, since the "pension recommendation" 1002 and the "pension cheap place" 1003 correspond to the rules according to the first string, the "pension recommendation" 1002 or the "pension cheap place" 1003 is provided to the user. The search result may include the advertisement of the advertiser. On the other hand, since the "pension way" 1004 does not correspond to the rule according to the first string, the search result provided to the user who inputs the "pension way" 1004 does not include the advertisement of the advertiser.

As such, when the advertisement providing method or the advertisement providing system according to the third embodiment of the present invention is used, a first string is input by an advertiser according to a predetermined rule, and a second string input by a user is input to the first string. In the case of following the rule, an advertisement of the advertiser may be provided to the user.

In step S1101, the advertisement providing system maintains at least one keyword set composed of a plurality of keywords. In this case, the keyword set may be selected from among a set of keywords purchased by the same advertiser. For example, in the advertisement providing system, if six keywords are purchased by the first advertiser and ten keywords are purchased by the second advertiser, the advertisement providing system may include the set of the six keywords and the set of the ten keywords. You can select and maintain a set of keywords. In this case, by using a rule that the six keywords must be included in the ten keywords, a more relevant keyword set can be selected and maintained.

Alternatively, the keyword set may be selected from a set classified based on a degree of association between words included in each keyword for a plurality of keywords. Here, the degree of association between the words is, for example, a word included in a document set, a document, a word classification for the word or a document classification for the document to obtain the word statistics information to form the word statistical information, It can be measured based on the formalized word statistical information. Since the method for measuring the degree of association between the words are various and already known, a detailed description thereof will be omitted.

In operation S1102, the advertisement providing system identifies an advertiser who purchases a predetermined number or more of keywords included in the keyword set. For example, the advertisement providing system may identify advertisers purchasing four or more keywords among keywords of a keyword set including a total of ten keywords by identifying keywords purchased by advertisers.

In step S1103, the advertisement providing system stores the plurality of keywords included in the keyword set as keywords for the identified advertiser's advertisement. That is, advertisers purchasing more than a predetermined number of keywords among the keywords of the keyword set may be extended to purchase all the keywords included in the keyword set.

In operation S1104, when the stored keyword is input by the user, the advertisement providing system provides an advertisement of the confirmed advertiser. That is, when a keyword is expanded to a keyword set including 10 keywords for an advertiser who has purchased 5 keywords, the advertiser's advertisement may have more exposure opportunities, and the operator of the advertisement providing system may receive more impressions. You can get higher advertising revenue. In this case, the advertisement of the advertiser may be provided to the user by setting a link to a web page including the advertisement of the advertiser on a search result page provided to the user for the keyword.

Here, the degree of association between the words is, for example, a word included in a document set, a document, a word classification for the word or a document classification for the document to obtain the word statistics information to form the word statistical information, It can be measured based on the formalized word statistical information. Since the method for measuring the degree of association between the words are various and already known, a detailed description thereof will be omitted.

The advertiser identification unit 1202 identifies an advertiser who purchases a predetermined number or more of the keywords included in the keyword set. For example, the advertiser verification unit 1202 may identify the advertisers who have purchased four or more keywords among the keywords of the keyword set including a total of ten keywords by checking the keywords purchased by the advertisers.

The keyword storage unit 1203 stores the plurality of keywords included in the keyword set as keywords for the identified advertiser's advertisement.
