Description

  The present invention relates to an advertisement fee setting system and an advertisement fee setting program for setting an advertisement fee to be displayed on a homepage on the Internet.

  In recent years, Internet users who use the Internet while turning on TVs and radios, and Internet users who access homepages that have posted topics on TV programs and radio programs are increasing. Get more detailed information on diet foods and health foods featured in the program, such as when the topic of a particular diet foods and health foods is about the greatest effect. As a result, access to related websites is concentrated. Such concentration of access occurs during a program or within a predetermined time after the program.

  On the other hand, it has become common to display advertisements on homepages and the like in order to browse advertisements for Internet users who access the homepages. A predetermined fee is required to display an advertisement on a homepage or the like, and the advertisement fee for displaying an advertisement is determined by a cumulative value of the number of accesses, a bid, or the like (for example, Non-Patent Document 1). And Non-Patent Document 2).

Specifically, there is a method called CPC (Cost per Click) in which a charge per click is determined in advance and the advertisement charge is obtained by multiplying the number of clicks (for example, Non-Patent Document 1). reference.). In addition, in the auction type advertising system such as overture disclosed in Non-Patent Document 2, a method of determining the order of displaying advertisements according to the bid amount and reflecting this fee on the advertising fee is taken. (For example, see Non-Patent Document 2).

  However, such a conventional advertisement fee setting technique has a problem that the advertisement fee cannot be set according to the access reflecting the topicality.

  Furthermore, in the method of determining the order of advertisement according to the bid amount, the advertiser needs to present a higher bid price in order to display higher, and the advertisement fee may be excessively high. There was a problem.

  The present invention has been made to solve such a problem, and can determine an advertising fee according to whether or not the appearance frequency of a keyword is abnormal, and does not set an advertising fee by bidding, reflecting topicality. An object is to provide an advertisement fee setting system and an advertisement fee setting program capable of facilitating setting of an advertisement fee.

  In view of the above points, the invention according to claim 1 is directed to an advertisement search means for searching and extracting an advertisement that matches the input keyword, an advertisement database that stores information related to the advertisement, and the input keyword. Keyword frequency measuring means for measuring the frequency of appearance of the matching input keyword used for the search when an advertisement matching the keyword is extracted, a keyword frequency table for storing information relating to the frequency of appearance of the keyword, and keywords within a predetermined time period Frequency abnormality determining means for determining that the appearance frequency of the keyword is abnormal when the appearance frequency of the keyword exceeds a predetermined height, and determining the advertisement fee depending on whether the appearance frequency of the keyword is abnormal or not Means.

  Further, in the present invention described in claim 2, in the claim 1, the advertising fee determination means may determine a different fixed amount according to whether or not it is determined that the keyword appearance frequency is abnormal, An amount obtained by multiplying a different fixed unit price depending on whether or not the occurrence frequency is determined to be abnormal and the appearance frequency of the matching input keyword in the time period is determined as the advertisement fee.

  Also, in the present invention described in claim 3, in the claim 1, when the advertising fee determination unit does not determine that the appearance frequency of the keyword is abnormal, the adaptation input of the time zone to a fixed amount or a fixed unit price. The amount multiplied by the keyword appearance frequency is determined as the advertising fee, and when it is determined that the keyword appearance frequency is abnormal, the unit price corresponding to the appearance frequency of the matching input keyword in the time period is calculated as the appearance frequency response unit price. Then, an amount obtained by multiplying the appearance frequency response unit price by the appearance frequency of the matching input keyword in the time period is determined as the advertisement fee.

  In addition, according to a fourth aspect of the present invention, in the second or third aspect, the frequency abnormality determining unit is configured such that the frequency of appearance of the keyword is high, and from each time zone to the next time zone. Based on a change in the appearance frequency of the keyword, it is detected whether or not the appearance frequency of the keyword is due to manual operation, and the advertising fee determining means is configured so that the frequency abnormality determining means determines that the appearance frequency of the keyword is manual operation. When it is detected that the advertising fee is not, an amount obtained by reducing the amount of the advertising fee calculated above is determined as the advertising fee.

  In addition, according to a fifth aspect of the present invention, in any one of the first to fourth aspects, the advertising fee setting system further calculates a degree of coincidence between the input keyword and information related to the advertisement. The advertising fee determining unit changes the advertising fee determined in accordance with the matching degree.

A pricing system and an advertising pricing program can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a block configuration of an advertisement fee setting system according to the first embodiment of the present invention. In FIG. 1, an advertisement fee setting system 100 searches for and extracts advertisements that match an input keyword (hereinafter referred to as input keyword), and information related to advertisement (hereinafter referred to as advertisement data). An advertisement database 120 that stores information, a keyword frequency measuring means 130 that measures the frequency of input keywords (hereinafter referred to as conforming input keywords) used to search for the extracted advertisements, and a keyword that stores information relating to the appearance frequency of keywords. Frequency table 140, frequency abnormality determining means 150 for determining whether or not “keyword appearance frequency is abnormal”, and advertisement fee determining means 160 for determining an advertising fee according to whether or not “keyword appearance frequency is abnormal” With.

  In FIG. 1, a keyword input by a user of the Internet is input to the advertisement search means 110 via a network. The advertisement search means 110 searches and extracts advertisement data that matches the input keyword from the advertisement data stored in the advertisement database 120.

  Here, as shown in FIG. 2, the advertisement data stored in the advertisement database 120 includes an advertisement ID for identifying an advertisement, an advertiser name, an advertisement itself created by the advertiser or at the request of the advertiser. Ad body, keywords related to advertisements (hereinafter referred to as advertisement-related keywords), cumulative advertising fees that are the total of advertising fees from the past to the present, date of creation of ads, and start of advertising Predetermined information such as the date and the publication end date is included, and the search is performed on the link URL of the advertisement or an advertisement-related keyword to be hit by a search by a search engine. The advertisement-related keyword includes other information such as the name of the advertisement target product, the selling point of the advertisement target product name, the performance of the advertisement target, and the name of the provider of the product.

  When the advertisement search means 110 extracts advertisement data having advertisement-related keywords that match the input keyword, the advertisement search means 110 outputs the matched input keyword used for the search to the keyword frequency measurement means 130. The keyword frequency measuring unit 130 measures the appearance frequency of the matching input keyword when the matching input keyword is input from the advertisement search unit 110. Here, the information on the appearance frequency of the suitable input keyword is, for example, the keyword frequency table 140 for each time period divided by a predetermined time width such as 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, 1 hour or the like. It is assumed that it is stored in

  The keyword frequency measuring unit 130 has a clock function, and when a suitable input keyword is input, out of the appearance frequencies of the keywords stored in the keyword frequency table 140, a time period including a time when the compatible input keyword is input. The appearance frequency of the matching input keyword is updated by one, and the updated information is output to the frequency abnormality determining unit 150 as a measurement value of the appearance frequency of the matching input keyword.

  Here, in the keyword frequency table 140 referred to in FIG. 3, in addition to the keyword appearance frequency information, thresholds required when the frequency abnormality determination unit 150 determines “abnormality of keyword appearance frequency”. Predetermined information such as (hereinafter referred to as a determination threshold) is stored. Further, the keyword frequency table 140 may record information related to the variation amount of the keyword appearance frequency and other information.

  That is, as shown in FIG. 3, for example, when the keyword is “diet”, the threshold of “5-minute frequency” is “30”, and the threshold of 10-minute frequency is “30”, “15 minutes” The threshold value of “Frequency” is set to “50”. Similarly, thresholds are set for the frequencies at other times, and threshold values are set for each of the other keywords in the same manner.

  When the measurement value of the appearance frequency of the matching input keyword is input, the frequency abnormality determination unit 150 determines that “the abnormality in the appearance frequency of the keyword is based on the input measurement value and the determination threshold value stored in the keyword frequency table 140. Is determined. The determination of whether or not “keyword appearance frequency is abnormal” is determined when the input measurement value exceeds the determination threshold, and it is determined that “keyword appearance frequency is abnormal” during that time period. When the value is equal to or lower than the threshold, it is determined that the “abnormality of keyword appearance frequency” has not occurred.

  Based on the determination result of whether or not “keyword appearance frequency is abnormal”, the advertising fee determination means 160 determines the advertising fee or the unit price of the advertising fee for that time zone and outputs it to the outside. Hereinafter, it is assumed that the unit price of the advertising fee is for one access, and when the advertising fee determining means 160 outputs the advertising fee, the unit price of the advertising fee is determined first, and the appearance frequency of the input keyword suitable for this unit price (the number of accesses) ) Shall be output as the advertising fee. Further, the advertising fee when it is not determined as “abnormality of keyword appearance frequency” is referred to as a normal advertising fee, and the advertising fee when it is determined as “abnormality of keyword appearance frequency” is referred to as a congestion-time advertising fee.

  Specifically, the unit price of the advertising fee is determined as follows. In other words, the unit price of the normal advertising fee is used until it is determined that the keyword occurrence frequency is abnormal in each time zone, and the unit price of the congested advertising fee is determined when the keyword occurrence frequency is abnormal. Switch. Therefore, in the time zone after the time zone determined as “abnormal keyword appearance frequency”, the unit price of the normal advertising fee is set as the unit price of the advertising fee until it is determined as “abnormal frequency of keyword appearance”. Yes.

  From the advertising fee determination means 160, the product of the unit price of the advertising fee set at the end of each time period multiplied by the appearance frequency (number of accesses) of the compatible input keyword is output to the outside as the advertising fee. However, it is possible to output the unit price of the advertisement fee and output other information.

  A method for determining the amount corresponding to the appearance frequency as the advertisement fee will be described in detail below. FIG. 4 is a diagram showing each of the above time zones when the time width is 15 minutes, the appearance frequency of the matching input keyword in each time zone, and the advertising fee and the unit price of the advertising fee in each time zone. FIG. 4 shows an example in which the determination threshold value for determining whether or not “keyword appearance frequency is abnormal” is 50 accesses in 15 minutes.

  In the example shown in (1) in FIG. 4, the unit price of the advertising fee up to 50 accesses not determined as “keyword appearance frequency abnormality” is 5 yen, and “keyword appearance frequency abnormality” is determined. The unit price of the advertising fee has been switched to 10 yen. In FIG. 4, the appearance frequency of the matching input keyword in the time zone specified by the symbol T (hereinafter referred to as the time zone of time T) is 40, and it is not determined as “abnormality in the appearance frequency of the keyword”, and the advertisement The unit price is 5 yen, and the advertising fee is 200 yen.

  Next, in the time zone of time T + 15 minutes, the appearance frequency of the matching input keyword is 70, and it is determined that “the occurrence frequency of the keyword is abnormal”, the unit price of the advertising fee is 10 yen, and the advertising fee is 700 yen. ing. Here, the number of accesses has increased, reflecting the fact that media related to the relevant input keyword have been talked about in media such as television. Then, the appearance frequency of the matching input keyword increases until time T + 30 minutes and time T + 45 minutes, and becomes 110 and 140, respectively, and the state determined as “abnormal keyword appearance frequency” continues, and the advertising fee is also increased. According to this, they are 1100 yen (unit price 10 yen) and 1400 yen (unit price 10 yen), respectively.

  After that, at the time T: 60 minutes, the state determined as “abnormality of keyword appearance frequency” continues, but the appearance frequency of the matching input keyword decreases to 80, and the advertising fee is also in accordance with this. It drops to 800 yen (unit price 10 yen). Finally, the appearance frequency of the matching input keyword is 50 accesses in the time period of time T + 75 minutes, and it is not determined that “the occurrence frequency of the keyword is abnormal”, and the unit price of the advertising fee is accordingly 5 yen. The amount is

  In the above example (1), the example in which the unit price of the advertising fee is switched after it is determined that “the occurrence frequency of the keyword is abnormal” has been described. It may be set to be a function. Specifically, as shown in the example of (2) in FIG. 4, the unit price of the advertising fee may be proportional to the appearance frequency. The advertising fee at this time is shown below the unit price. By doing in this way, it is possible to further set a fee according to the topic level.

  In the above, an example of access according to topicality and an advertising fee according to appearance frequency has been described, but as in this example, access according to topicality usually has a predetermined time spread and common sense Has an upper limit. This is due to the fact that the access is made by manual operation, the frequency of appearance of the access is reduced by repeating the access, and a large amount of access cannot be made by manual operation like a computer.

  FIG. 5 is a diagram for explaining an example of a method for determining an advertisement fee for alleviating or preventing an advertisement fee from becoming large due to unintended access such as a DOS (Denial of Service) attack. In the example shown in FIG. 5, the appearance frequency of the matching input keyword shows an abnormally high value of 950 only in the time zone of time T + 45 minutes, and shows a normal common sense value in other time zones. In other words, the appearance frequency of the matching input keyword suddenly increases in the time zone of time T + 45 minutes.

  Such a change in the appearance frequency of the matching input keyword cannot be considered due to an increase in access according to topicality. Therefore, in a predetermined case such as when the frequency abnormality determination unit 150 detects the appearance frequency of a very high suitable input keyword for a short time, the advertisement fee determination unit 160 causes the advertisement fee to be abnormally high during that time period. Decide the advertising fee to suppress.

  In the example shown in FIG. 5, the appearance frequency of the suitable input keyword in the time zone of time T + 45 is 950, which is the appearance frequency of the very high suitable input keyword in a short time, and the calculation method of the advertisement fee is shown in Example (1). An example is shown in which the method of multiplying the unit price by the appearance frequency (number of accesses) of the appropriate input keyword is changed to the method of multiplying the unit price by the appearance frequency converted to (500 + 100 × 1n (appearance frequency / 100)). Here, “1n” indicates a natural logarithm, and other numbers indicate constants.

  Further, in the example (2) of FIG. 5, when the method shown in the example (2) of FIG. 4 is used as the advertising fee calculation method, when an increase in the appearance frequency of the suitable input keyword that does not correspond to the topicality is detected. In this example, the unit price is converted to (10 + 10 × 1n (appearance frequency / 100)), and this unit price is multiplied by the appearance frequency converted to (100 + 10 × 1n (appearance frequency / 100)). Here, “1n” indicates a natural logarithm, and other numbers indicate constants.

  In this way, in order to prevent the advertisement fee from becoming abnormally high, for example, a function that suppresses an extreme increase in natural logarithm or the like using the appearance frequency of the matching input keyword as an argument may be used. Thereby, it is possible to prevent the advertisement fee from being inappropriately increased due to a DOS attack or mischief. However, the detection method of the increase in the appearance frequency of the suitable input keyword not depending on the topicality and the calculation method of the advertisement fee when it is detected are not limited to the above methods, and the appearance frequency of the suitable input keyword not depending on the topicality is detected. You may change according to the aspect of a raise.

  Information necessary for determining the advertisement fee is stored in advance in the advertisement fee determining means 160. The information required to determine the advertising fee includes, specifically, the limit price, fixed fee, the method of charging when it is determined that “the occurrence of the keyword is abnormal”, and the appropriate input keyword that does not depend on the topicality. This includes information such as a method for detecting an increase in appearance frequency and a method for calculating an advertising fee when detected.

  FIG. 6 is a diagram showing a specific block configuration of the advertisement fee setting system 100 according to the first embodiment of the present invention. As shown in FIG. 6, the advertising fee setting system 100 is configured by a computer having a communication function, etc., and implements the receiving unit 401 to which a predetermined signal such as a keyword is input and the functions of the advertising fee setting system 100. A CPU (Central Processing Unit) 403 that performs predetermined information processing, a ROM (Read Only Memory) 402 that stores an OS (Operating System) for starting up the CPU 403, other programs, parameters, and the like, and the CPU 403 are in operation. RAM (Random Access Memory) 404 for storing the execution code and data of the OS and application to be used, advertisement data, keyword appearance frequency information, predetermined data such as a judgment threshold, advertisement charge Information necessary for the constant, and includes a hard disk 405 that stores application software nonvolatile and rewritable to, and transmission means 406 for outputting a predetermined signal, such as advertising rates.

  Hereinafter, the operation of the advertisement fee setting system 100 according to the first embodiment of the present invention will be described. FIG. 7 is a flowchart for explaining the operation of the advertising fee setting system 100 according to the first embodiment of the present invention.

  First, a keyword input by a user of the Internet is received by the receiving unit 401 via the Internet and output to the CPU 403 serving as the advertisement search unit 110 (step 510: S510).

  Next, the advertisement data stored in the hard disk 405 as the advertisement database 120 is searched for by the CPU 403 as the advertisement search means 110 using the input keyword, and the matching advertisement data is stored in the advertisement database 120. If there is no matching advertisement data, the response to the input keyword is terminated (step 520: S520).

  When matching advertisement data is extracted in step 520, the input keyword is set as the matching input keyword, and the appearance frequency of the matching input keyword is measured by the CPU 403 as the keyword frequency measuring unit 130 (step 530: S530). Here, the details of the appearance frequency measurement have been described above, and thus the description thereof is omitted.

  When the appearance frequency of the matching input keyword is measured in step 530, based on the measured value of the appearance frequency of the matching input keyword and the determination threshold stored in the hard disk 405 as the keyword frequency table 140, “keyword appearance frequency Whether or not "abnormal" is determined by the CPU 403 as the frequency abnormality determining means 150 (step 540: S540). Note that data with a small data capacity such as the appearance frequency is read in advance from the hard disk 405 as the keyword frequency table 140, stored in the RAM 404, and the CPU 403 refers to and updates the data stored in the RAM 404. But you can.

  When it is determined in step 540 whether or not “keyword appearance frequency is abnormal”, the advertising fee is determined by the CPU 403 as the advertising fee determination means 160 according to the determination result of “keyword appearance frequency is abnormal”. It is determined and output to the outside (step 550: S550). The determination as to whether or not the “appearance frequency of the keyword is abnormal” and the method for determining the advertisement fee have been described in detail above, and thus the description thereof will be omitted.

  As described above, in the advertising fee setting system according to the first embodiment of the present invention, the advertising fee determining means determines the advertising fee according to whether or not the appearance frequency of the keyword is abnormal. It is possible to make it easy to set the advertising fee reflecting the topicality without setting the advertising fee by.

  Also, by setting a fixed amount as the advertising fee depending on whether or not it is determined that the keyword appearance frequency is abnormal, a clear amount can be set as the advertising fee, and the fixed unit price is multiplied by the appearance frequency of the appropriate input keyword. By setting the selected amount as the advertising fee, it is possible to set an advertising fee that more reflects the topicality.

  In addition, since the amount of money obtained by multiplying the appearance frequency response unit price according to the appearance frequency of the suitable input keyword by the appearance frequency of the suitable input keyword is determined as the advertisement fee, it is possible to set the advertisement fee more reflecting the topicality.

  In addition, the advertising fee determination means determines the amount of the already calculated advertising fee as the advertising fee when the keyword appearance frequency is not due to manual operation. Can be prevented from soaring.

  In addition, since the advertising fee determining means determines the advertising fee to the advertiser's limit price, it is possible to set a price that can easily satisfy the advertiser.

  In the first embodiment of the present invention, the advertisement fee setting method for performing the processes in the above steps 510 to 550 using the advertisement fee setting system 100 has been described. It is also possible to implement using a predetermined computer in which an advertisement fee setting program for executing the advertisement fee setting operation including step 550 is installed.

  The advertising fee setting program of the present invention may be recorded on an existing recording medium, or may be provided via a network such as the Internet.

(Second Embodiment)
In the first embodiment of the present invention, the configuration has been described in which the frequency abnormality determination unit 150 determines whether or not “keyword appearance frequency is abnormal” using one determination threshold value. In the embodiment, a description will be given of a form in which “abnormality of keyword appearance frequency” is determined by dividing it into a plurality of levels (hereinafter referred to as keyword appearance frequency abnormality levels) using a plurality of determination thresholds.

  FIG. 8 is a diagram showing a block configuration of an advertisement fee setting system according to the second embodiment of the present invention. In FIG. 8, the advertising fee setting system 600 according to the second embodiment of the present invention uses a frequency level instead of the frequency abnormality determining means 150 of the advertising fee setting system 100 according to the first embodiment of the present invention. The determination means 450 is provided. Here, the keyword frequency table 140 stores a plurality of determination threshold values and operates as follows.

  In the following description, it is assumed that the determination frequency stored in the keyword frequency table 140 is two. The two determination threshold values are referred to as a first determination threshold value and a second determination threshold value, respectively, and the first determination threshold value is lower than the second determination threshold value. When the measurement value of the appearance frequency of the matching input keyword is input, the frequency level determination unit 450 receives the keyword appearance frequency abnormality level based on the input measurement value and the two determination threshold values stored in the keyword frequency table 140. Determine.

  The keyword appearance frequency abnormality level is determined by determining the “keyword appearance frequency abnormality level” to be level 1 when the input measurement value exceeds the first determination threshold value and is equal to or less than the second determination threshold value. When the value is equal to or lower than the second determination threshold value, the level is determined to be level 2. When the value is equal to or lower than the first determination threshold value, the “keyword appearance frequency abnormality level” is set to level 0 and “keyword appearance frequency abnormality” does not occur. Is determined.

  The advertising fee setting system 600 determines the keyword appearance frequency abnormality level in step S740 shown in FIG. At that time, at one or more levels from level 1 to level 3, a method for determining the amount designated by the advertiser's limit as the advertising fee, and a method for determining the amount designated by the advertisement distributor as the advertising fee There are a method of determining the amount of money according to the appearance frequency as the advertisement fee, a method of calculating the advertisement fee when an increase in the appearance frequency of the matching input keyword not depending on the topicality is detected, and the like. However, it is not necessarily limited to these determination methods, and other determination methods may be used. The above advertisement fee determination processing is performed by the advertisement fee determination means 160 in step S750 shown in FIG.

  As described above, the advertising fee setting system according to the second embodiment of the present invention determines an abnormality in the appearance frequency of keywords by dividing it into a plurality of levels in addition to the effect of the first embodiment of the present invention. However, since different advertisement charges can be set at each level, more detailed advertisement charges can be set.

  In the second embodiment of the present invention, the advertisement fee setting method has been described in which the advertisement fee setting system 200 is used to perform the processes in the above steps S510, S520, S530, S740, and S750. It is also possible to implement using a predetermined computer in which an advertisement fee setting program for executing the advertisement fee setting operation including these steps S510, S520, S530, S740 and S750 is installed.

  The advertising fee setting program of the present invention may be recorded on an existing recording medium, or may be provided via a network such as the Internet.

(Third embodiment)
FIG. 10 is a diagram showing a block configuration of an advertisement fee setting system according to the third embodiment of the present invention. As shown in FIG. The advertisement fee setting system 800 according to the third embodiment of the present invention calculates the degree of matching of keywords in the search performed by the advertisement search means 110 to the advertisement fee setting system 100 according to the first embodiment of the present invention. The degree of coincidence calculation means 870 is added.

  Here, the degree of matching of keywords refers to the degree to which the input keyword matches the advertisement-related keyword extracted by the search, and is sometimes referred to as similarity. As a method for the coincidence calculation means 870 to calculate the coincidence, for example, there is a method described below. First, as a first method, there is a method of dividing the total number of matching characters when the input keyword and the advertisement related keyword are overlapped by the total number of characters constituting the advertisement related keyword.

  Specifically, when the word “hatch bag” is input as an input keyword, the degree of coincidence with the advertisement-related keyword “hatchback” is calculated as follows. First, the number of characters in the “hatchback” is calculated in the order in which the characters constituting the “hatchback” are located. Here, “ha”, “tsu”, “ba”, and “tsu” match each character in the “hatch bag”, and 4 is calculated as the total number of matching characters. Then, the total number 4 of characters overlapping with the advertisement-related keyword is divided by the total number 5 of characters constituting the advertisement-related keyword, and 0.8 is calculated as the degree of coincidence.

  Next, as a second method, the input keyword is divided into a plurality of overlapping parts (hereinafter, each divided part is referred to as “element character”). ), A method of checking whether or not each element character matches a character in the advertisement-related keyword to be searched, and using the ratio of the matched element character with respect to the total number of element characters as the matching degree.

  Specifically, when the word “hatch bag” is input as an input keyword, the degree of coincidence with the advertisement-related keyword “hatchback” is calculated as follows. First, the word “hatch bag” is divided into element characters “hatch”, “hatch”, “chiba”, “bag”, and “g”. Next, the element characters included in the “hatchback” are counted. In the above example, four element characters (“hatch”, “hatch”, “chiba” and “bah”) among the above five element characters are included, so the element characters included in “hatchback” are 4 Finally, the number of element characters 4 included in the advertisement-related keyword is divided by the total number of element characters 5, and 0.8 is calculated as the degree of coincidence.

  In the above, an example of dividing an element character into two characters has been described. However, even if an element character is divided into three or more characters and the degree of coincidence is calculated, it is divided into a plurality of types of characters such as two characters and three characters. Alternatively, the total number of matches may be calculated, and the degree of match may be calculated by dividing by the total number of divided characters. Also, as a method for calculating the degree of coincidence, a method for calculating the degree of coincidence between keywords having different numbers of characters, a method for calculating the degree of coincidence for a plurality of keywords having similar meanings, and the like are known, and various calculation methods can be applied. .

  Here, in the advertisement fee setting system 800, the advertisement fee determining means 160 of the advertisement fee setting system 100 becomes the advertisement fee determining means 860, and the sign is changed. This indicates that the method for calculating the advertisement fee by the advertisement fee determining unit 860 is partially different from the method for calculating the advertisement fee determining unit 160. In the third embodiment of the present invention, the advertising fee determination unit 860 determines the advertising fee based on the determination result output from the frequency abnormality determination unit 150 and the matching degree information output by the matching degree calculation unit 870. To do.

  This is because the topicality is reflected as the degree of matching between the keyword input to the advertisement search means 110 and the keyword related to the advertisement data extracted from the advertisement database 120 increases. The determination of the advertising fee performed by the advertising fee determining means 860 is that when the matching degree information reflecting the topicality at the time of determining the advertising fee is equal to or less than a predetermined value, the advertising fee is determined as “abnormality of keyword appearance frequency”. A method for determining a charge when not determined, a method for determining a charge based on a value obtained by multiplying the measured value of the appearance frequency of the keyword output from the keyword frequency measuring unit 130 via the frequency abnormality determining unit 150 by the degree of coincidence, etc. The determination method reflects the degree of coincidence information.

  Although the above description is based on the determination result output from the frequency abnormality determination unit 150, the present invention is not necessarily limited to this, and the frequency level determination according to the second embodiment of the present invention shown in FIG. It may be based on the level information output from the means 450. In addition, each component other than the coincidence calculating unit 870 and the advertising fee determining unit 860 constituting the advertising fee setting system 800 is the same as that described with reference to FIG. 6 in the first embodiment of the present invention. Therefore, the description is omitted.

  Hereinafter, the operation of the advertisement fee setting system 800 according to the third embodiment of the present invention will be described. FIG. 11 is a flowchart for explaining the operation of the advertising fee setting system 800 according to the third embodiment of the present invention. In FIG. 11, the same processes as those described in the first embodiment of the present invention are denoted by the same reference numerals, and the description thereof is omitted.

  When it is determined in step 540 whether or not “keyword appearance frequency is abnormal”, the degree of matching between the input keyword and the keyword related to the advertisement data extracted from the advertisement database 120 is calculated by the advertisement searching unit 110. 870 is performed (step 950: S950).

  When the degree of coincidence is calculated in step 950, the advertisement fee taking into account the degree of coincidence is determined by the advertisement fee determining means 860 and output to the outside (step 960: S960). Note that the processing in step 950 is not necessarily performed after the processing in step 540, and may be performed at any timing as long as it is performed after step 510 and before step 960.

  As described above, the advertisement fee setting system according to the third embodiment of the present invention has the keyword input to the advertisement search means 110 and the advertisement database 120 in addition to the effects of the first embodiment of the present invention. Since the degree of match with the advertising-related keywords extracted from is reflected in the advertising fee, it is easier to set the advertising fee reflecting the topicality, and a higher fee is set for a more appropriate advertisement can do.

  In the third embodiment of the present invention, the advertisement fee setting method for performing the processes in steps 510 to 540, 950, and 960 using the advertisement fee setting system 800 has been described. It is also possible to implement using a predetermined computer in which an advertisement fee setting program for executing the advertisement fee setting operation including these steps 510 to 540, step 950 and step 960 is installed.

  The advertising fee setting program of the present invention may be recorded on an existing recording medium, or may be provided via a network such as the Internet.

  The advertisement fee setting system and the advertisement fee setting program according to the present invention are advantageous in that it is possible to easily set an advertisement fee reflecting topicality without setting an advertisement fee by bidding. It can also be applied to uses such as an advertisement fee setting system and an advertisement fee setting program.
