Taking the dialog content shown in FIG. 4 as an example, words such as "travel" and "overseas" existing in the character string of this dialog are extracted. Further, the word “Brazil” is extracted, and it is counted that this word is used twice.

The advertisement search unit 5 searches and confirms whether or not the extracted word matches the advertisement word recorded in the advertisement dictionary 4 (step S13). If there is a match, the advertisement content of the corresponding word is selected (step S13). That is, the advertisement dictionary 4 searches for an advertising word that matches “travel”, “overseas”, and “Brazil”, gives priority to the word that is frequently used in the dialogue, and selects “Brazil travel” from the overseas travel advertisement. Select

As shown in FIG. 5, the advertisement providing unit 6 records a link to the item “Brazil” for the advertisement of overseas travel in the dialogue recording unit 2 in the format of “advertisement: click here for travel to Brazil”. The advertising device 1a outputs to each user and displays it on the terminals A, B and C. When each user clicks the character, the information is recorded in the dialog recording unit 2 and input to the advertisement search unit 5.
