Ad keyword search system and how to provide keyword ads {SYSTEM FOR SEARCHING ADVERTISEMENT KEYWORD AND METHOD FOR PROVIDING RECOMMENDED ADVERTISEMENT KEYWORD}

The present invention relates to a search system and a search service providing method, and more particularly, to an advertisement keyword search system and a method for providing a recommended advertisement keyword.

Recently, with the rapid increase in the Internet use population, the Internet search site is in the spotlight as a new advertising means. Advertisers can promote their businesses or products by displaying banner ads on search sites or by exposing their homepage or products when searching. Can generate advertising revenue in return for Looking at this in more detail as follows.

The search site operator sells the advertisement keyword to the advertiser through an advertisement keyword search system. Here, the advertisement keyword refers to a search word related to a predetermined advertisement among search words input by the Internet users in the search box.

For example, if an Internet user wants to search a homepage of a related company to use a "flower delivery" service, enter "flower delivery" in a search box and obtain information about the company through a search result. Therefore, the Ad Keyword Search System selects and sells highly relevant words such as "Flower Delivery" to the advertiser and advertises them to the advertiser. When an Internet user enters "Flower Delivery" into the search box, the advertiser's homepage address And so on to the search screen.

However, even when an internet user wants to obtain the same information, various search terms may be input in the search box. For example, when a user wants to search a homepage of a flower delivery service company, an internet user may input various search terms such as "flower", "flower delivery" or flower delivery service.

Therefore, when the advertiser wants to purchase a predetermined advertisement keyword, the conventional advertisement keyword search system provides a similar advertisement keyword as the recommended advertisement keyword for the corresponding advertisement keyword. Here, the similar advertising keyword is to consider various search environments by various Internet users, and means that groups of keywords corresponding to similar businesses or typical products of the corresponding industry are grouped.

For example, when an advertiser of a flower delivery service company wants to purchase an "flower delivery service" advertisement keyword, similar advertisement keywords such as "flower delivery" and "flower basket" are provided as recommended advertisement keywords. Through this, the advertiser can increase the advertising effect by increasing the frequency of exposure of the company homepage by purchasing similar advertising keywords together.

However, as described above, the conventional advertisement keyword search system that provides only similar advertisement keywords has a problem in that it does not sufficiently reflect the actual search terms because only the case where the user inputs the correct keyword in the search box is considered. Here, the actual search term refers to a search word actually input by an internet user in a search box, and includes a search word written with a typo or a similar pronunciation. For example, in the case of "flower delivery," a search term such as "dump delivery", "flower delivery" or "flower delivery" may be entered. In the case of "compass", "compass", A practical search word such as "compass" may be input.

Since a conventional advertising keyword search system does not consider such a practical search term, there is a limit in that it is not possible to recommend an advertising keyword reflecting an actual internet usage environment to an advertiser. In addition, since the input of the practical search term as described above occurs particularly frequently in the middle-aged people who are not familiar with the computer or the Internet, if it does not reflect the actual use of the Internet by the middle-aged people who have relatively high purchasing power, it is expected to have sufficient advertising effect. There is a problem that can not be.

The present invention has been proposed to solve the above problems, and proposes an advertisement keyword search system and a method for providing recommended advertisement keywords that automatically recommend a real-time search term including a typo or a similar reading with respect to an advertisement keyword input by an advertiser. It aims to do it.

The present invention proposed to achieve the above object is an advertisement keyword search system, comprising: an input unit for receiving an advertisement keyword from a user; A storage unit that stores a real-time search word including a typo or a similar reading sound that may be generated when a search word is input to a search box; And an extracting unit which extracts a real search term matching the input advertisement keyword from the storage unit.

The present invention also provides a search system comprising: an input unit for receiving a search word from a user; A real-world search term selecting unit that selects a real-time search word including a typo or a similar reading type that was input incorrectly from the search word received through the input unit; A storage unit to store the selected actual search word; And an extracting unit extracting the actual search term matching the input search word from the storage unit.

In addition, the present invention provides a method for providing a recommended advertising keyword, the step of receiving an advertising keyword from the user; Storing a real-time search word including a typo or a similar reading sound generated when a search word is input to a search box in a storage unit; And extracting, from the storage unit, a real-time search word matching the input advertisement keyword.

In addition, the present invention provides a search service providing method for providing a recommended advertising keyword, comprising: receiving a search word from a user; Selecting a real-use search word including a typo or a similar reading that is incorrectly input from the search word received through the input unit; Storing the selected actual search word in a storage unit; And extracting, from the storage unit, the actual search word matching the received search word.

According to the present invention, it is possible to automatically provide a recommended advertising keyword to the advertiser by automatically recommending a real-time search word including a typo or a similar reading matched with the advertisement keyword input by the advertiser. In particular, it is possible to improve the efficiency of the search by providing a real-time search word input to the search box by the Internet user to the advertiser in real time. According to the present invention, it is possible to improve the advertising effect by providing the advertiser with a recommended advertising keyword reflecting the actual Internet usage environment.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of an advertisement keyword search system and a network according to an embodiment of the present invention. The ad keyword search system refers to a system that provides a recommended ad keyword for an advertiser who wants to purchase an ad keyword. Here, the ad keyword means a search term related to a predetermined advertisement among search terms inputted into a search box by Internet users. do.

First, the configuration of the entire network is as follows. As shown in FIG. 1, the search server 110 provides a search service to an Internet user 100 connected to a search system through a terminal. Here, the Internet user 100 refers to a person who accesses a search system in order to use a conventional search service. In this case, the search server 110 refers to a real-world search word among search terms inputted into a search box by the Internet user 110. Select and transmit to the advertising keyword search system 120.

Here, the actual search term refers to a search word actually input by an internet user in a search box, and includes a typo or a similar reading sound that may occur when the internet user inputs a search word in a search box. Here, the typo means that some of the spellings of the search word are incorrectly input, and the similar reading phoneme is input with the pronunciation similar to the words interposed in the dictionary. In particular, when a word composed of a foreign word is inputted in Korean according to a reading, it is likely to be selected as a practical search word.

The search server 110 may compare the search word input by the Internet user 100 to the search word and the word intervened in the dictionary to select the actual search term. As a result of the comparative analysis of the search word and the words contained in the dictionary, if the search word is not included in the dictionary, it is determined that there is an error in spelling or that it is described as a similar reading, and the word is selected as the actual search word. In this case, it is preferable that the dictionary referred to as a criterion for selecting a practical search word from the search server 110 includes both a Korean dictionary, an English dictionary, an encyclopedia, and the like.

For example, if an Internet user wants to search for "flower delivery" in the search box, some misspellings may be misspelled in the search box, such as "pick delivery," "flower delivery," or "flower delivery." . In addition, in the case of "compass", it should be input as "compass" when using a foreign language notation, but may be input as "compass", "compass", etc. similar in pronunciation. In this case, the search server 110 selects the corresponding word as the actual search term and transmits the selected actual search term to the advertisement keyword search system 120.

Alternatively, the actual search term may be selected through the search pattern of the Internet user 100. After the Internet user 100 performs a search by entering a first search term in the search box, does not take any action on the search result, and performs a search by entering a second search term as a re-search term and then links to the search result. When clicking, it can be seen that the user has not obtained the desired search result through the first search word. That is, the first search word may be regarded as a typo or similar reading. Accordingly, the search server 110 selects the first search word as a practical search word and transmits it to the advertisement keyword search system 120.

Next, the configuration of the advertisement keyword search system 120 will be described. As shown in FIG. 1, the advertisement keyword search system 120 includes an input unit 121, a storage unit 123, and an extracting unit 124, and preferably, a phoneme converter 122 or a provider 125. More). Here, the advertisement keyword search system 120 collects information necessary for providing an advertisement keyword search service through communication with the search server 110, for example, a real search term, and transmits the information to the advertisement keyword search system 120 through a terminal. An advertisement keyword search service is provided to the accessed advertiser 130.

The input unit 121 receives an advertisement keyword from an advertiser 130 connected to the advertisement keyword search system 120 through a user, that is, a terminal.

The phoneme converter 122 converts the advertisement keyword received from the advertiser 130 and the actual search word received from the search server 110 into phonemes. In this case, it is preferable to convert the received advertising keyword and the actual search term into phonemes, and then convert the converted phonemes into phonemes, and a predetermined rule may be applied in the process of converting phonemes into phonemes.

As an embodiment of the present invention, a few rules for converting phonemes to phonemes are as follows. First, the phoneme converter 122 may apply a rule for deleting the corresponding phoneme “ㅇ ㅇ” when the phoneme “” follows the phoneme “”. In this case, "Nateon" is converted to the phoneme "ㄴ ㅔ ㅇ ㅣ ㅌ ㅡ ㅇ ㅗㄴ" and then to the phoneme "ㄴ ㅔ ㅇ ㅣ ㅌ ㅗㄴ". Second, if the phoneme "ㄱ, ㄲ, ㄳ, ㅋ" followed by the phoneme "ㄱ, ㄲ, ㅋ", the rule to convert the phoneme to "ㄱ" can be applied. In this case, "each" is converted to the phonemes "a, ㅏ, a, a, k, a" and then to the phonemes "a, a, b, a, k, a". Third, when the word ends with the phoneme "ㅏ, ㅑ, ㅓ, ㅓ, ㅕ, ㅗ ,,, TT, ㅠ, ㅡ, ㅣ, ㅘ, ㅚ, ㅝ, ㅟ" followed by the phoneme "ㄲ, ㅋ" , You can apply the rule to convert the phoneme "ㄲ, ㅋ" to "ㄱ". In this case, the "kitchen" is converted to the phoneme "ㅂ ㅜㅇ ㅓㅋ" and then to the phoneme "ㅂ ㅜㅇ ㅓㄱ". Fourth, if the phoneme "b, 다음 에, ㄶ, ,, 규칙" followed by the phoneme "" ", the rule to delete the phoneme" ㄵ, ㄵ, ㄶ, ,,, "may apply. In this case, "sitting" is converted to the phoneme "ㅇㅏ ㄵ ㄴ ㅡ ㄴ" and then to the phoneme "ㅇ ㅏㄴ ㅡ ㄴ". Fifth, if the phoneme "ㄵ, ㅊ" is followed by the phoneme "B, ㅇ", the rules for changing the phoneme to "ㅈ" can be applied. In this case, "sitting" is converted to the phoneme "ㅇㅏ ㄵ ㅇ ㅡ ㄴ" and then to the phoneme "ㅇ ㅏㅈ ㅡ ㄴ". The phoneme converter 122 may also convert the received advertising keywords into phonemes by applying various rules.

The storage unit 123 stores a real-time search word including a typo or a similar reading sound that may occur when the search word is input to the search box. Here, the actual search term may be received from the search server 110 and stored, and the stored actual search term may be updated in real time. In addition, the storage unit 123 preferably stores similar advertisement keywords by grouping or stores the advertisement keywords selected by the advertiser 130.

In this case, the storage unit 123 may store the corresponding word in a form converted into phonemes by the phoneme converter 122 when storing the actual search word, the similar advertisement keyword, or the selected advertisement keyword. In particular, by storing phonemes in a ternary search tree structure, the stored information can be managed systematically and the information processing speed can be increased.

The extractor 124 extracts the actual search term matching the advertisement keyword received from the advertiser 130 from the storage unit 123. At this time, the extraction unit 124 is substantially the same as the phone number and the advertising keywords received according to the edit distance or edit score calculated by comparing the advertising keywords received from the advertiser 130 and the actual search words stored in the storage unit 123. It is preferable to extract the actual search word, and in particular, it is more preferable to extract substantially the same search word in consideration of the editing distance and the edit score. Here, the meaning that the phonemes are substantially the same means that the calculated editing distance or editing score falls within a predetermined range. In other words, the spelling is written in some incorrect or similar readings, but there are some phonetic differences that can be considered by the user to describe the same intention.

In this case, the edit distance is a number of different phonemes that are sequentially compared with phonemes of two words, and may be calculated using a NN (Near Neighbor) algorithm. For example, when comparing the phonemes "ㅅㅏㄹ ㅏㅇ" and "ㅅㅏㄹ ㅏㅁ" between "love" and "person", the editing distance is 1 because the last phoneme is different, and the lower the similarity of the two words, the larger the value of the editing distance. .

In addition, the editing score is a measure indicating the degree to which the two words differ, and is calculated by adding or subtracting a predetermined score according to phonetic similarity between phonemes or the position of the keyboard. For example, the score may be set higher as the phonetic similarity between the phonemes is low or the location of the keyboard is far from each other, so that the phoneme is incorrectly inputted.

Phoneme of the received ad keywords Comparison phoneme Addition or subtraction points A A -100 A ㄲ +100 A Lol +150 A Other phonemes +500

Table 1 shows an editing score calculation method according to an embodiment of the present invention. In comparing the phonemes of two words in turn, by subtracting a predetermined score for the same phoneme and adding a predetermined score for different phonemes, the degree of the two words can be represented as an editing score. In this case, the addition or subtraction score may be set according to the pronunciation similarity or the position of the keyboard as described above.

Here, the extractor 124 sets the maximum edit distance or the maximum edit score of the input advertising keyword, and extracts the actual search term whose calculated edit distance or edit score is within the set maximum edit distance or the maximum edit score. desirable. In particular, it is more preferable to extract the actual search word that satisfies both the maximum edit distance and the maximum edit score.

In this case, the maximum edit distance and the maximum edit score may be preset in consideration of the number of letters or the phoneme of the advertisement keyword, or may be calculated based on a predetermined practical search word.

Character count Phoneme number Editing distance Edit score One One 0 0 One 2 or more One 500 2 5 or less 2 800 2 6 2 900 3 6 or less 3 900 3 7 to 8 3 1400 3 9 or more 4 1800

Table 2 is a table showing the maximum edit distance and the maximum edit score set according to the number of letters and phonemes according to an embodiment of the present invention. For example, when "love" is input from the advertiser 130 as an advertisement keyword, since the corresponding advertisement keyword corresponds to 2 characters and 5 phonemes, the maximum edit distance is 2 and the maximum edit score is set to 800. Accordingly, by extracting the actual search term within the maximum edit distance 2 and the maximum edit score 800 from the storage unit 123, it is possible to efficiently extract the matched actual search term.

Alternatively, the maximum edit distance and the maximum edit score may be calculated based on a predetermined actual search term. For example, if an internet user 100 enters a first search term in the search box and then does no action on the search result and performs a re-search on the second search term and clicks a link in the search result, The user may not be able to obtain a desired search result through the first search word. That is, the first search word may be viewed as a typo or similar reading sound for the second search word, and when the second search word is regarded as an advertisement keyword, the first search word may be regarded as the most practical practical search word. Accordingly, the extraction unit 124 sets the edit distance and the edit score calculated by comparing the phonemes of the first search word and the second search word as the second search word, that is, the maximum edit distance and the maximum edit score of the advertisement keyword.

In addition, the extractor 124 may be configured to delete a predetermined phoneme of an advertisement keyword or add a predetermined phoneme to a predetermined location when comparing phonemes, and then calculate an editing distance or an editing score. For example, in the process of inputting a search word in the search box, the Internet user 100 who wants to input "flower delivery" further types a predetermined embroidery, such as "flower delivery", or a predetermined embroidery, such as "cockle delivery". Less typing can occur. Therefore, the extractor 124 may arbitrarily reduce or expand the length of the phonemes in order to more efficiently extract the actual search words having different numbers of words or phonemes.

For example, if the advertiser 130 receives the advertisement keyword "flower delivery", the phoneme "ㄲ ㅗ ㅊㅂ ㅐ ㄷㅏㄹ" as well as "* ㄲ ㅗ ㅊㅂ ㅐ ㄷㅏㄹ", "ㄲ * ㅗ ㅊㅂ ㅐ ㄷㅏ", " "*" You can extract the actual search terms using "ㅏ ** ㄹ" and "ㄲ ㅗ ㅊㅂ ㅐ ㄷㅏㄹ *".

Here, "*" means that any phoneme is added to the corresponding position. When the number of letters or phonemes of the input advertisement keyword is greater than or equal to a predetermined value, one or more phonemes may be added to the predetermined location. For example, consider adding two phonemes, such as "** ㄲ ㅗ ㅊㅂ ㅐ ㄷㅏㄹ".

Or "ㅗ ㅊㅂ ㅐ ㄷㅏㄹ", "ㄲ ㅊㅂ ㅐ ㄷㅏㄹ", "ㄲ ㅗㅂ ㅐ ㄷㅏㄹ", "ㄲ ㅗㅊ ㅐ ㄷㅏㄹ", "ㄲ ㅗ ㅊㅂ ㄷㅏㄹ", "ㄲ ㅗ ㅊㅂ ㅐ ㅏㄹ", "ㄲ ㅗ ㅊㅂ ㅐ ㅏㄹ", "ㄲ ㅗ ㅊㅂ ㅐ The actual search term may be extracted on the assumption that arbitrary phonemes, such as ㄷㄹ "and" ㄲ ㅗ ㅊㅂ ㅐ ㄷㅏ ", are deleted. At this time, any phoneme may be set not to be deleted.

In addition, when similar advertising keywords are grouped and stored in the storage unit 123, the extraction unit 124 may extract a similar advertising keyword group including an advertising keyword input from an advertiser. In addition, when the advertisement keyword selected by the other advertiser is stored in the storage unit 123, the advertisement keyword selected by the other advertiser matching the advertisement keyword input from the advertiser 130 may be extracted.

The provider 125 provides a recommended advertisement keyword including the actual search term extracted by the extractor 124 to the advertiser 130 who inputs the advertisement keyword. In this case, the recommended advertisement keyword may include an advertisement keyword selected by a similar advertisement keyword or another advertiser.

2 is a diagram illustrating a search system and a network configuration according to an embodiment of the present invention. In FIG. 1, a case in which a function of extracting and using a real search term matching an advertisement keyword is provided by a separate advertisement keyword search system has been described. Hereinafter, in FIG. 2, the corresponding function is an additional function in a conventional search system. It describes the case when implemented as.

First, the configuration of the entire network is as follows. As shown in FIG. 2, the search system 220 provides a search service through communication with the terminals 200 and 210. In this case, the terminals 200 and 210 which are connected to the search system 220 may be divided into two types. First, there may be a terminal accessing the search system 220 in order to use a conventional search service, hereinafter referred to as an internet user 200. In addition, there may be a terminal accessing the search system 220 to use the advertisement keyword search service, hereinafter referred to as an advertiser 210.

Next, the configuration of the search system 220 will be described. As shown in FIG. 2, the search system 220 includes an input unit 221, a practical search term selecting unit 222, a storage unit 224, and an extracting unit 225, and preferably, a phoneme conversion unit ( 223 or the provider 226 is further included.

The input unit 221 receives a search word from a user, that is, an Internet user 200 or an advertiser 210 connected to the search system 120 through a terminal. Here, the conventional search service is provided for the search word input from the Internet user 200 in the search box, and the search word input from the advertiser 210 is recognized as an advertisement keyword. In this case, the Internet user 200 and the advertiser 210 may be distinguished through member information.

The actual search term selecting unit 222 selects the actual search term from among the search terms inputted into the search box by the Internet user 200 and stores the search term in the storage unit 224. Here, the actual search term selecting unit 222 compares and analyzes the words entered in the search box by the Internet user 200 and the words included in the dictionary, and spells the search terms when the search terms are not included in the dictionary. It may be determined that there is an error or is described as a pseudo-negative sound, and the corresponding search word may be selected as a practical search word. At this time, the selection of the actual search word is preferably performed in real time with respect to the search word input by the Internet user 200, and the dictionary referred to as a criterion for the selection of the actual search word includes a Korean dictionary, an English dictionary, an encyclopedia, etc. It is preferable to include.

Alternatively, the actual search term may be selected through the search pattern of the Internet user 200. If the Internet user 200 enters the first search term in the search box and then does not take any action on the search result and performs a re-search on the second search term and clicks a link in the search result, the user clicks the link in the search result. The search term did not result in the desired search results. That is, the first search term may be regarded as a practical search term including a typo or similar reading. Thus, the actual search term selecting unit 222 selects the first search term as the actual search term and stores it in the storage unit 224.

The phoneme converter 223 converts a search word received from the user 200 or 210 into phoneme. In this case, after converting the search word into phoneme, it is preferable to convert the converted phoneme into phoneme, and a predetermined rule may be applied in the process of converting the phoneme into phoneme. Details related to the phoneme converter 223 are the same as described with reference to FIG. 1.

The storage unit 224 stores the actual search term selected by the actual search term selecting unit 222. Here, the storage unit 224 may update the real-time search word selected by the real-time search word selector 222 in real time. In addition, the storage unit 224 preferably stores similar advertisement keywords by grouping or stores the advertisement keywords selected by the advertiser 210. In particular, the storage unit 225 may store the search word converted into phonemes by the phoneme converter 223.

The extractor 225 extracts a search term input from the advertiser 210, that is, a real search term matching the advertisement keyword, from the storage 224. In this case, the extractor 225 may extract an appropriate actual search term according to the edit distance or the edit score calculated by comparing the advertisement keyword received from the advertiser 210 with the actual search term stored in the storage 224. . In particular, it is more preferable to extract substantially identical actual search words in consideration of the editing distance and the editing score.

In this case, the maximum edit distance or the maximum edit score is set in advance according to the number of letters or the phonemes of the input advertisement keyword, or the maximum edit distance or the maximum edit score is preset based on a value calculated based on a predetermined practical search term, and calculated. It is preferable to extract the actual search word whose edited distance or edit score is within the set maximum edit distance or maximum edit score. In particular, it is more preferable to extract the actual search word that satisfies both the maximum edit distance and the maximum edit score.

In addition, the extractor 225 preferably calculates an editing distance or an editing score after deleting a predetermined phoneme or adding a predetermined phoneme to a predetermined location when comparing phonemes.

In addition, when similar advertising keywords are grouped and stored in the storage unit 224, the extraction unit 225 may extract a similar advertising keyword group including an advertising keyword input from an advertiser. In addition, when the advertisement keyword selected by the other advertiser is stored in the storage unit 224, the advertisement keyword selected by the other advertiser matching the advertisement keyword input from the advertiser 210 may be extracted. Details related to the extractor 225 are the same as described above with reference to FIG. 1.

The provider 226 provides the recommended advertisement keyword including the actual search term extracted by the extractor 225 to the advertiser 210 who inputs the advertisement keyword. In this case, the recommended advertisement keyword may include an advertisement keyword selected by a similar advertisement keyword or another advertiser.

3 is a flowchart illustrating a method for searching an advertisement keyword according to an embodiment of the present invention.

First, an Internet user 100 who wants to use a conventional search service accesses a search server 110 through a terminal and inputs a search word in a search box (S310). The search server 110 selects a real-use search word from among search terms received from the Internet user 100 (S320), and transmits it to the advertisement keyword search system 120 (S330).

Subsequently, the storage unit 123 of the advertisement keyword search system stores the actual search term received from the search server 110 (S340). In addition, the storage unit 123 may store similar advertisement keywords by grouping them or store the advertisement keywords selected by other advertisers. Subsequently, the input unit 121 receives an advertisement keyword from the advertiser 130 connected to the advertisement keyword search system 120 through the terminal (S350).

Subsequently, the phoneme converter 122 converts the received advertising keyword and the actual search term into phonemes (S360), and the extractor 124 stores the actual search term that matches the advertisement keyword received from the advertiser 130. Extracted from 123 (S370). In this case, the extractor 124 may compare the phonemes of the input commercial keyword and the actual search term stored in the storage unit 123, and extract the matched actual search term based on the calculated editing distance or the edit score.

Subsequently, the provider 125 provides the advertiser 130 with a recommended advertisement keyword including the actual search term extracted by the extractor 124 (S380). In this case, as described above, when the similar advertising keywords are stored in a group stored in the storage unit 123 or an advertisement keyword selected by another advertiser is stored, the providing unit 125 may store the actual search term, the similar advertising keyword, or another advertiser. The recommended advertisement keyword including the selected advertisement keyword may be provided to the advertiser 130.

Subsequently, some of the recommended advertisement keywords provided by the provider 125 may be selected by the advertiser 130 (S390), and the selected advertisement keywords may be stored in the storage unit 123 (S395).

In the advertisement keyword search system 120, a detailed method of providing a recommended advertisement keyword including a practical search term that matches the input advertisement keyword is the same as described with reference to FIG.

4 is a flowchart illustrating a search method according to an embodiment of the present invention.

First, when an Internet user 200 who wants to use a conventional search service accesses a search system 220 through a terminal and inputs a search word in a search box, the search system 220 inputs a search word through the input unit 221. Received (S410). At this time, the search system 220 transmits the corresponding search result to the Internet user 200 (S420), and the actual search term selecting unit 222 may incorrectly input a typo or a similar reading sound among search terms received through the input unit 221. In operation S440, the actual search term including the selected real-use search word selector 222 may be stored in operation S440. Here, the storage unit 224 may store similar advertisement keywords by grouping or storing advertisement keywords selected by other advertisers.

Subsequently, the input unit 221 receives the advertisement keyword from the advertiser 210 connected to the search system 220 through the terminal to search for the advertisement keyword (S450). Subsequently, the phoneme converter 223 converts the received advertising keyword and the actual search term into phonemes (S460), and the extractor 225 stores the actual search term that matches the advertisement keyword received from the advertiser 210. Extracted from 224 (S470). At this time, the extraction unit 225 may compare the phonemes of the received advertising keyword and the actual search word stored in the storage unit 224, and extracts the actual search word that is matched according to the calculated editing distance or edit score.

Subsequently, the provider 226 provides the advertiser 210 with a recommended advertisement keyword including the actual search term extracted by the extractor 225 (S480). In this case, as described above, when the similar advertising keywords are stored in the storage unit 224 as a group or stored in the advertisement keywords selected by other advertisers, the providing unit 226 may store the actual search terms, similar advertising keywords, or other advertisers. The recommended advertisement keyword including the selected advertisement keyword may be provided to the advertiser 210.

Subsequently, some of the recommended advertisement keywords provided by the provider 226 may be selected by the advertiser 210 (S490), and the selected advertisement keywords may be stored in the storage unit 224 (S495).

In the search system 220, a detailed method of providing a recommended advertisement keyword including a search term input from the advertiser 210, that is, a practical search term matching the advertisement keyword, is the same as that described with reference to FIG. 2.

The method of the present invention as described above may be embodied as a program and stored in a computer-readable recording medium (such as a CD-ROM, a RAM, a ROM, a floppy disk, a hard disk, or a magneto-optical disk). Since this process can be easily implemented by those skilled in the art will not be described in more detail.
