When product decomposing information is not extracted, a representative type name corresponding to the type name of a product is extracted from a type name/representative type name correspondence information storing means and used as a keyword to retrieve the product decomposing information (ST300). Then the retrieved result is judged (ST400), and the product decomposing information is not extracted yet, the feature information of the product such as the inches of a screen of a television e.g. is used as a keyboard to retrieve product decomposing information (ST500). |
