Description

  The present invention relates to a search technology for electronic leaflet information in the case where leaflet advertisement publication information is converted into image data and registered in a database.

  Advertisers automatically input flyer advertisement information including advertisement condition information and flyer advertisement images into the advertisement format provided by the flyer advertisement collection and distribution site operator, and automatically transfer it to the Internet during the specified advertisement period. 2. Description of the Related Art A flyer advertisement distribution system that publishes a flyer advertisement and browses it on a customer terminal (for example, see Patent Document 1). According to this advertisement distribution system, an electronic flyer advertisement is created based on a “flyer advertisement” that is an advertisement paper and published on the Internet, and a terminal on the customer side can search and browse a desired electronic flyer advertisement. .

  In addition, when the customer's information terminal sends information such as the general name of the search target product or product classification to the information processing device of the management center by e-mail or access to the homepage, the information processing device relates to the information received by the information processing device. There is known a method for distributing special product information in which special product information to be searched is searched from a special product information database and is sent to a customer information terminal by e-mail (see, for example, Patent Document 2).

JP 2005-78159 A JP 2005-209134 A

However, in the advertisement distribution system described in Patent Document 1, the customer terminal can set the advertisement condition information as a search condition. The advertisement condition information includes the terminal identifier, the request date, the registration number, the area code, the advertisement. It is a condition, type of business, presence / absence of correction, data type, and other remarks columns, and an electronic flyer advertisement can be searched only by basic conditions regarding a flyer advertisement such as a region and an advertisement period.
In addition, since the distribution method described in Patent Document 2 distributes the sale information on the products corresponding to the purchase needs of the customer by e-mail, even if the purchase needs of the customer can be used as input for search, only the sale information is searched. Can not do it.

  When a consumer desires to purchase a product, the name of the store or the place of purchase may not be determined even though the name of the desired product is clear. For example, it is clear that the name of a product that wants to purchase Carrero is clear, but it is not yet decided at which store to purchase. However, in the prior art, it was not possible to search for electronic leaflet advertisements based on the product name “Carreru” and to extract and browse electronic leaflet advertisements of stores selling Carrero.
