The local keyword may also include the name of the upper administrative area of the administrative area included in the address. For example, if the address entered by the advertiser is "Yeouido-dong Yeouido-dong", it is a name corresponding to "city", which is the upper administrative section of the district, "Yeongdeungpo" "Seoul" can be included in the local keyword.

The local keyword may also include other names of previously stored administrative regions associated with the names of administrative regions included in the address.

In the case where the administrative area of the name requested for purchase is not the administrative area of the predetermined unit, even if the purchase of the corresponding name is allowed through the inspection, only the corresponding advertiser is allowed to purchase the corresponding name. Purchase may not be automatically permitted.

In addition, as described above, the names of the administrative districts and aliases for the names of spots can also be purchased by the advertiser. Even in this case, acceptance of purchase can be determined through inspection. For example, the name of the spot "Seoul Admission Zone" is often used as an alias such as "Irreplaceable" or "Entered Zone". In this case, whether or not an alias such as "Laughing" or "Entering Area" can be used as a local keyword can be determined through inspection. At this time, an alias for a name of a spot to which purchasing is permitted through inspection may be included in the database as a generic name of the spot described above, and an alias for the name of the administrative area for which purchase is allowed through inspection is referred to as the name of the administrative area And may be included in other names of administrative district names associated and previously stored.

In this case, the purchasable keyword determination unit 220 can extract the industry keyword associated with the business type from the table to determine the business type keyword.

In addition, the purchasable keyword determination unit 220 may determine at least one keyword as a purchasable keyword based on the number of queries (Query Count, QC) of each of the keywords configured through the combination of the local keyword and the business keyword. For example, the purchasable keyword determining unit 220 may determine at least one keyword having a maximum number of times of searching for a month in the previous year as a purchasable keyword among the keywords constituted through combination of a local keyword and a business keyword . For example, only keywords with a maximum number of searches of 30 or more per month in the previous year can be sold as available keywords.

In addition, the purchasable keyword determining unit 220 may determine the local keyword to include the name of the administrative area within the predetermined area range according to the business type among the names of the administrative areas determined according to the address.

For example, when a user searches for a "restaurant" near "Nonhyun station" and a user searches for a "pension" near "Mt. Sorak", a distance range Is likely to be much shorter than the distance between "Mt. Seoraks" and "pensions". Therefore, the purchasable keyword determination unit 220 may set different regional ranges according to the type of business, and determine the local keywords for the regions within the predetermined range of the business type. For example, in the case of a business type related to "restaurant", the purchasable keyword determining unit 220 can determine the name of the administrative region included within a radius of 2 km as a local keyword, and in the case of an industry related to "pension" The name of the administrative district included within 30 km may be determined as the local keyword.

In this manner, the purchasable keyword determining unit 220 can determine the purchasable keyword by further using various additional factors besides the address and industry.

The purchasable keyword providing unit 230 provides the determined purchasable keyword to the advertiser. For example, when an advertiser inputs an address and an industry type in an advertiser site in order to purchase a keyword, the purchasable keyword determination unit 220 can determine a purchasable keyword. At this time, the purchasable keyword providing unit 230 may provide the purchasable keyword determined by the advertiser by exposing the purchasable keyword determined through the advertiser site.

The storage unit 240 stores at least one available keyword selected by the advertiser among the supplied available keywords in association with at least one page of the advertisement page of the advertiser and the business information page allocated to the advertiser.

At this time, if the user who accesses the site of the publisher inputs the search word, the publisher can extract the keyword from the search word and transmit the keyword to the advertisement providing system 200 through the advertisement platform. In this case, the advertisement providing system 200 may search for the keyword of interest corresponding to the delivered keyword and the at least one page stored in association with the retrieved interest keyword. In addition, the advertisement providing system 200 may provide information about the searched at least one page (for example, URL information of the page) to the publisher.

The advertisement providing system according to another embodiment of the present invention can remove the non-local keywords from the combination keywords constituted by the combination of the local keyword and the business keyword, and determine the purchasable keyword through the remaining combination keywords. For example, if you look at the combination keyword "child dress" composed of a combination of the local keyword "child" and the industry keyword "dress" according to the local name "childhood" It is not clear whether you want to search for a dressing company located in the United States, or search for a company selling "child" dresses. In addition, "Chuncheon chicken ribs" and "Cheongyang chili" can also be used to search for companies related to "chicken ribs" or "chili" located in the local "Chuncheon" or "Cheongyang" It is not clear whether you want it. Therefore, it is necessary to remove the non-local keywords from the combination keywords constituted by the combination of the local keyword and the industry keyword.

8 is a block diagram for explaining an internal configuration of an advertisement providing system according to another embodiment of the present invention. The advertisement providing system 800 according to the present embodiment may be a system associated with one of the plurality of individual advertisement platforms included in the advertisement platform 120 described with reference to FIG. The advertisement providing system 800 may include a non-local keyword holding unit 810, an information providing unit 820, a keyword removing unit 830, and a purchasable keyword determining unit 840 as shown in FIG. have.

The non-local keyword retaining unit 810 stores and maintains the non-local keyword in the non-local keyword database, which is determined as the non-local keyword among the combination keywords constituted by the combination of the local keyword and the business type keyword. Since the local keyword and the industry keyword have already been described in detail, the repetitive description will be omitted.

At this time, whether or not the combination keyword is a non-local keyword can be determined through a combination of at least two of the following four methods or each of the following four methods. For example, in the second method, the third method or the fourth method is reapplied for the combination keyword determined as the non-local keyword, so that the second method and the third method, or both the second method and the fourth method, Combination keywords can also be stored in a non-local keyword database.

First, as a first method, a combination keyword can be classified into one of a local keyword and a non-local keyword using user feedback information. Here, the user feedback information may be generated through a user interface for selecting which keyword of the combination keyword corresponds to which of the localization keyword and the non-localization keyword, and the user interface may include a search result page Lt; / RTI > For example, if the user who entered the search term "child dress" is informed that the search result desired by the user through the search result page is related to a business related to "dress" A user interface can be selected. At this time, when the user selects the latter, the combination keyword "child dress" may be classified as a non-local keyword and stored in the non-local keyword database.

As a second method, the combination keyword can be determined as a non-local keyword if the local keyword included in the combination keyword is included as a normal noun in the Korean dictionary. For example, the local keyword "child" is included in the Korean dictionary as a common noun, meaning "a person who is physically and mentally immature", and the local keyword "Garak" Mental efficiency or mood ". Therefore, the combination keyword including the local keyword "child" or "rhythm " can be determined as the non-local keyword.

As a third method, a non-local keyword may be determined based on a retrieval count (Query Count, QC) of at least one other combination keyword constituted by a combination of an industry keyword included in the combination keyword and another local keyword have. For example, the combination keyword may be determined as a non-local keyword when the number of searches of at least one other combination keyword constituted through a combination of the industry keyword included in the combination keyword and another local keyword is equal to or less than a predetermined number. If the search frequency of the other combination keyword "dress per minute" or "Seoul dress" is less than or equal to the predetermined number of times for the combination keyword "child dress ", the combination keyword" child dress " In this case, in the third method described above, the search frequency of the other combination keywords is described as a criterion for determining whether the combination keyword is the non-local keyword. However, the number of searches is only one example for explaining the above-described criteria, and the index used as a criterion for discriminating whether or not a combination keyword is a non-local keyword is not limited to the number of searches. For example, with respect to the above-described other combination keywords, various indicators known to be measurable with respect to the keyword, such as the residence time of the user who visited the web page through click satisfaction, click rate, or other combination keywords, . If the residence time is used as an index used as a criterion for discriminating whether or not a keyword is a non-local keyword, if the residence time according to the other keyword is less than a preset time, the keyword may be determined as a non-local keyword .

In the fourth method, the non-local keyword may be determined based on the number of retrieval (Query Count, QC) of the keyword which is composed of the combination of the local keyword included in the combination keyword and the related keyword of the industry keyword included in the combination keyword have. For example, when the number of searches of at least one keyword constituted by a combination of the local keyword included in the combination keyword and the related keyword of the industry keyword included in the combination keyword is equal to or less than a predetermined number, it can be determined as the non-local keyword. If the number of searches for the other combination keyword " Mapo charcoal ribs "or" Mapo ribs "is less than or equal to the predetermined number of times for the associated keyword " charcoal rib" or " If so, the combination keyword " mapo ribs "can be determined to be a non-local keyword.

In the fourth method, the related keyword can be selected based on the degree of association with the business type keyword. For example, a related keyword for a business type keyword can be selected based on the degree of association between words of each keyword. At this time, the method of selecting a keyword according to the degree of association is already well known, so a detailed description will be omitted.

The information providing unit 820 provides the address of the company and the business type of the company entered from the advertiser who intends to purchase the keyword. For example, when an advertiser inputs business information to purchase a keyword for a local advertisement, the information providing unit 820 confirms the business address of the business and the business information of the business entered together with the business name or business telephone number from the advertiser . At this time, the address of the company can be input in the form of text by the advertiser, and the business type of the business can be inputted by selecting from among various business category categories by the advertiser. Here, the business category may be configured to have a plurality of depths, such as an upper category and a lower category.

The keyword removal unit 830 removes the non-local keywords stored in the non-local keyword database from the combination keywords constituted by a combination of the local keyword selected according to the address and the business keyword selected according to the business type. As described above, since the non-local keywords are judged to reduce the accuracy of the local search results, the non-local keywords can be removed from the combined keywords.

The purchasable keyword determining unit 840 determines at least one of the combination keywords from which the non-local keywords are removed as the purchasable keyword. The method of determining the purchasable keyword and the method of providing the determined purchasable keyword to the advertiser have already been described in detail, and a repetitive description will be omitted.

As described above, by removing the non-local keyword from the combination keyword formed by combining the local keyword and the business keyword with the advertisement providing system 800, more accurate local advertisement can be provided.

9 is a flowchart illustrating an advertisement providing method according to another embodiment of the present invention. The advertisement providing method according to the present embodiment can be performed by the advertisement providing system 800 described with reference to FIG. 9, a description will be given of a method of providing an advertisement by explaining a process in which the respective steps are performed by the advertisement providing system 800. FIG.

In operation 910, the advertisement providing system 800 stores and maintains a keyword determined as a non-local keyword in the non-local keyword database among the combination keywords constituted by the combination of the local keyword and the business keyword. Since the local keyword and the industry keyword have already been described in detail, the repetitive description will be omitted.

At this time, whether or not the combination keyword is a non-local keyword can be determined through a combination of at least two of the following four methods or each of the following four methods. For example, in the second method, the third method or the fourth method is reapplied for the combination keyword determined as the non-local keyword, so that the second method and the third method, or both the second method and the fourth method, Combination keywords can also be stored in a non-local keyword database.

First, as a first method, a combination keyword can be classified into one of a local keyword and a non-local keyword using user feedback information. Here, the user feedback information may be generated through a user interface for selecting which keyword of the combination keyword corresponds to which of the localization keyword and the non-localization keyword, and the user interface may include a search result page Lt; / RTI > For example, if the user who entered the search term "child dress" is informed that the search result desired by the user through the search result page is related to a business related to "dress" A user interface can be selected. At this time, when the user selects the latter, the combination keyword "child dress" may be classified as a non-local keyword and stored in the non-local keyword database.

As a second method, the combination keyword can be determined as a non-local keyword if the local keyword included in the combination keyword is included as a normal noun in the Korean dictionary. For example, the local keyword "child" is included in the Korean dictionary as a common noun, meaning "a person who is physically and mentally immature", and the local keyword "Garak" Mental efficiency or mood ". Therefore, the combination keyword including the local keyword "child" or "rhythm " can be determined as the non-local keyword.

As a third method, a non-local keyword may be determined based on a retrieval count (Query Count, QC) of at least one other combination keyword constituted by a combination of an industry keyword included in the combination keyword and another local keyword have. For example, the combination keyword may be determined as a non-local keyword when the number of searches of at least one other combination keyword constituted through a combination of the industry keyword included in the combination keyword and another local keyword is equal to or less than a predetermined number. If the search frequency of the other combination keyword "dress per minute" or "Seoul dress" is less than or equal to the predetermined number of times for the combination keyword "child dress ", the combination keyword" child dress " In this case, in the third method described above, the search frequency of the other combination keywords is described as a criterion for determining whether the combination keyword is the non-local keyword. However, the number of searches is only one example for explaining the above-described criteria, and the index used as a criterion for discriminating whether or not a combination keyword is a non-local keyword is not limited to the number of searches. For example, with respect to the above-described other combination keywords, various indicators known to be measurable with respect to the keyword, such as the residence time of the user who visited the web page through click satisfaction, click rate, or other combination keywords, . If the residence time is used as an index used as a criterion for discriminating whether or not a keyword is a non-local keyword, if the residence time according to the other keyword is less than a preset time, the keyword may be determined as a non-local keyword .

In the fourth method, the non-local keyword may be determined based on the number of retrieval (Query Count, QC) of the keyword which is composed of the combination of the local keyword included in the combination keyword and the related keyword of the industry keyword included in the combination keyword have. For example, when the number of searches of at least one keyword constituted by a combination of the local keyword included in the combination keyword and the related keyword of the industry keyword included in the combination keyword is equal to or less than a predetermined number, it can be determined as the non-local keyword. If the number of searches for the other combination keyword " Mapo charcoal ribs "or" Mapo ribs "is less than or equal to the predetermined number of times for the associated keyword " charcoal rib" or " If so, the combination keyword " mapo ribs "can be determined to be a non-local keyword.

In the fourth method, the related keyword can be selected based on the degree of association with the business type keyword. For example, a related keyword for a business type keyword can be selected based on the degree of association between words of each keyword. At this time, the method of selecting a keyword according to the degree of association is already well known, so a detailed description will be omitted.

In step 920, the advertisement providing system 800 provides the address of the company and the business type of the business entered from the advertiser who intends to purchase the keyword. For example, when an advertiser inputs business information to purchase a keyword for a local advertisement, the advertisement providing system 800 confirms the address of the business and the business type information of the business together with the business name or business telephone number from the advertiser . At this time, the address of the company can be input in the form of text by the advertiser, and the business type of the business can be inputted by selecting from among various business category categories by the advertiser. Here, the business category may be configured to have a plurality of depths, such as an upper category and a lower category.

In step 930, the advertisement providing system 800 removes the non-local keywords stored in the non-local keyword database from the combination keywords constituted by the combination of the local keyword selected according to the address and the business keyword selected according to the business type. As described above, since the non-local keywords are judged to reduce the accuracy of the local search results, the non-local keywords can be removed from the combined keywords.

In step 940, the advertisement providing system 800 determines at least one combination keyword among the combination keywords from which the non-local keywords have been removed as the purchasable keyword. The method of determining the purchasable keyword and the method of providing the determined purchasable keyword to the advertiser have already been described in detail, and a repetitive description will be omitted.
