== Propagation result registration process ==
FIG. 9 is a diagram showing a flow of processing for registering propagation information. Note that the processing of FIG. 9 is periodically performed at predetermined time intervals (for example, 1 minute, 5 minutes, 10 minutes, 1 hour, etc.).

  When the crawl unit 212 or the update detection unit 213 acquires post information (S501), the propagation result registration unit 214 displays campaign information whose post date is posted after the start date and time of the campaign and before the end date and time. Read from the database 251 (S502). The propagation result registration unit 214 performs the following processing for each campaign information.

  The propagation result registration unit 214 reads campaign word related information corresponding to the campaign ID of the campaign information from the campaign word dictionary 252 (S503). The propagation result registration unit 214 determines whether or not the campaign word is included in the posting information acquired in step S501 for each campaign word related information (S504). When the posting information includes a campaign word (S504: YES), the propagation result registration unit 214 sets the counter variable n to 0 (S505), and for each campaign word included in the posting information, Perform the process.

The propagation result registration unit 214 increments the variable n (S506), sets the evaluation coefficient of the campaign word related information to r (S507), and performs the affirmative word evaluation process shown in FIG. 10 (S508).
In FIG. 10, the propagation result registration unit 214 reads the affirmation word information corresponding to the campaign ID of the campaign word related information from the affirmation word dictionary 253 (S521), and for each read affirmation word information, It is determined from the position of the campaign word whether or not the affirmative word of the affirmative word information is included within a predetermined distance before and after (S522), and when the affirmative word is included within the predetermined distance (S522). : YES), the evaluation coefficient of the yes / no word information is added to r (S523). In this way, the evaluation coefficient is adjusted when a positive / negative word is present near the campaign word in the posted information. The negative word evaluation coefficient is set to a negative value, so if a negative word is included near the campaign word, the evaluation coefficient will be small, and the positive word evaluation coefficient will be set to a positive value. If an affirmative word is included near the word, the evaluation coefficient can be increased.

Next, the propagation result registration unit 214 performs the related word evaluation process shown in FIG. 11 (S509).
The propagation result registration unit 214 reads out the campaign ID of the campaign word related information and the combination information corresponding to the campaign word from the combination dictionary 254 (S541). For each combination information, the propagation result registration unit 214 determines whether or not a related word of the combination information is included within a predetermined distance from the position of the campaign word in the posted information (S542). If a related word is included in (S542: YES), the evaluation coefficient of the combination information is added to r (S543). In this way, when the related word is present near the campaign word in the posted information, the evaluation coefficient is adjusted.

  The propagation result registration unit 214 creates the propagation information including the campaign ID, the campaign word, the URL indicating the posted information, n, and r after repeating the processing from step S506 to S509 for each campaign word in the posted information. Then, the created propagation information is registered in the propagation result database 255 (S510). If the propagation information corresponding to the URL of the posting information is registered, the propagation result registration unit 214 deletes the propagation information and newly registers the created propagation information.

  The above processing is repeated for each campaign information, and propagation information for each campaign is registered in the propagation result database 255.

== Propagation intensity calculation process ==
FIG. 12 is a diagram showing a flow of propagation intensity calculation processing related to a campaign. The process of FIG. 12 may be performed each time the propagation result registration process is registered, or may be performed asynchronously with the propagation result registration process.

  The propagation intensity calculation unit 215 reads campaign information whose campaign end date and time is before the current date and time from the campaign advertisement database 251 (S561), and performs the following processing for each read campaign information. Note that the propagation intensity calculation unit 215 may read only those for which the charging flag is set to “not yet”.

  The propagation strength calculation unit 215 reads propagation information corresponding to the campaign ID from the propagation result database 255 (S562). The propagation intensity calculation unit 215 sets the number of read propagation information as the number of propagation persons (S563). In addition, the propagation intensity calculation unit 215 calculates a value obtained by multiplying the number of words and the evaluation coefficient for each propagation information, and calculates the propagation intensity by summing the values calculated for each propagation information (S564). The propagation strength calculation unit 215 updates the number of propagation people and the propagation strength of the campaign information corresponding to the campaign ID (S565).

  By repeating the above processing for each piece of campaign information, the number of propagation information and propagation intensity of the campaign information are updated. As described above, the billing processing unit 216 charges the advertiser according to the number of people and the propagation strength of the updated campaign information.

  The propagation intensity calculation unit 215 may output the result of the process in FIG. 12 as shown on a screen 60 in FIG. In the example of FIG. 13, for each campaign ID, the screen 60 displays the campaign word, the URL of the posting information including the campaign word, the propagation strength for each posting information, and the campaign propagation strength. Has been. The propagation strength for each post information is the coefficient r after step S509 of FIG. 9 is performed. The propagation intensity is a coefficient r at the time of proceeding to step S510 in FIG. The propagation intensity calculation unit 215 transmits, for example, screen data for displaying the screen 60 to the advertiser terminal 10, and the advertiser terminal 10 displays the screen 60, so that for each campaign performed by the advertiser, It is possible to confirm how the campaign words are used by the user and the degree of propagation of the campaign.

  As described above, according to the advertising billing system of this embodiment, billing according to the number of propagation persons and propagation intensity can be performed. In the advertising billing system of the present embodiment, the number of post information including campaign words, that is, the number of keywords that are strongly related to the campaign such as catch phrase and product name is actually posted from the user as the number of people to propagate. Can be charged. Therefore, it is possible to charge according to the number of users who post articles or the like using campaign words themselves. Therefore, the payment is based on the certain effect of the advertisement, and the satisfaction degree of the advertiser can be improved and the satisfaction of the advertiser can be improved. Further, by viewing the propagation intensity of the campaign and the URL of the posting information using the campaign word displayed on the screen 60 shown in FIG. 13, the advertiser can see how the campaign is transmitted to the user. It is possible to easily grasp whether it is.

  In addition, according to the advertisement billing system of the present embodiment, it is possible to calculate the propagation strength corresponding to the evaluation coefficient of the campaign word in the posted information and charge according to this propagation strength. For example, the product name that exists before the campaign is not limited to the effectiveness of the campaign, but in the advertising billing system of this embodiment, the product name evaluation coefficient is set lower than the catch phrase. Therefore, it is possible to accurately evaluate the degree of propagation of the campaign itself.

  Further, according to the advertisement billing system of the present embodiment, the propagation intensity can be adjusted depending on whether or not there is a positive word near the campaign word. Even if the posted information uses the same campaign word, there is a difference in terms of the effectiveness of the advertisement between when it is used in a negative sense and when it is used in a positive sense. Therefore, to accurately evaluate the propagation intensity of the campaign by increasing the propagation intensity when the affirmative word is near the campaign word and decreasing the propagation intensity when the negative word is near the campaign word. Can do.

  Further, according to the advertisement billing system of the present embodiment, the propagation intensity can be adjusted when related words exist near the campaign word. For example, if the product name is used at the same time as the name of the TV program that conducted the campaign, the product name can be considered to have been propagated to the user as an effect of the campaign, so the propagation intensity is highly appreciated. be able to. That is, the propagation intensity can be more accurately evaluated.

  In the advertising billing system according to the present embodiment, the number of pieces of posted information including the campaign word is set as the number of propagating people. However, the present invention is not limited to this. It is good also as a propagation number by counting.

  Further, in the advertising billing system of the present embodiment, in step S523 of FIG. 10 and step 543 of FIG. 11, the evaluation coefficient for the positive word and the evaluation coefficient for the related word are added to the evaluation coefficient for the campaign word. However, the present invention is not limited to this, and multiplication may be performed.

  In the advertising billing system of this embodiment, the appearance frequency (number of words) of the campaign word is multiplied by the evaluation coefficient to obtain the propagation intensity. However, only the appearance frequency may be used as the propagation intensity.

  In the advertising billing system of the present embodiment, the campaign word evaluation coefficient, the positive / negative word evaluation coefficient, and the related word evaluation coefficient are added and multiplied by the appearance frequency of the campaign word. The first value obtained by multiplying the appearance frequency of the campaign word by the evaluation coefficient of the campaign word, and the evaluation coefficient of the positive word and the campaign according to the frequency at which the positive word exists within a predetermined distance before and after the campaign word in the posted information. A second value obtained by multiplying the word evaluation coefficient, and a third value obtained by multiplying the frequency of the related word within a predetermined distance before and after the campaign word by the evaluation coefficient of the related word and the evaluation coefficient of the campaign word. And the first to third values may be summed to calculate the propagation intensity.

  Further, adjustment may be made so that the new post information has higher propagation intensity. In this case, the crawl unit 212 and the update detection unit 213 also acquire the update date / time of the posted information, and the propagation strength calculation unit 215 responds to the difference between the current date / time and the update date / time in step S510 of FIG. The coefficient is multiplied by r. Thereby, since the propagation intensity about newer information can be evaluated highly, an advertiser should just pay according to the present propagation intensity. Therefore, the satisfaction according to the advertiser can be improved by charging according to the current advertising effect.

  Further, the billing processing unit 216 may perform billing on a date basis. In this case, the crawl unit 212 and the update detection unit 213 acquire the update date and time of the posted information, and include the update date and time in the propagation information. In addition, the propagation strength calculation unit 215 calculates the number of propagation persons and the propagation intensity for each date specified from the update date and time, and registers the number of propagation persons and the propagation intensity for each date in the campaign advertisement database 251, thereby The unit 216 performs charging according to the number of propagation persons and propagation intensity for each date.
