<P>PROBLEM TO BE SOLVED: To improve targeting ability of an advertisement. <P>SOLUTION: An advertiser enters ad information. A keyword facility uses the entered ad information as seed information to infer one or more categories, provides candidate categories to the advertiser and asks him/her to confirm which of the categories are relevant to his/her ad. Keywords can be determined by using at least the categories. The determined keywords are provided to the advertiser as suggested keywords, or are automatically added to ad serving constraint information as targeting keywords. An ad server system uses the determined keywords on trial to decide whether they are qualified or disqualified as the targeting keywords. <P>COPYRIGHT: (C)2012,JPO&INPIT |
