Abstract: A system and method identify and provide content using identification entries. Product identification information for a product listing is received, and a matching identification entry is selected from a set of identification entries using the product identification information. The matching identification entry is assigned to the product listing for use in selecting content regarding the product listing for presentation.

Abstract: A system and method identify and provide content using identification entries. Product identification information for a product listing is received, and a matching identification entry is selected from a set of identification entries using the product identification information. The matching identification entry is assigned to the product listing for use in selecting content regarding the product listing for presentation.

Abstract: A method and a system that identify content within a network-based system are provided. The method and system may operate to receive a request including an identification from a device of a user, assign a matching identification entry to the identification or to the user using the identification and a set of identification entries comprising the matching identification entry, and transmit the matching identification entry to an identification module configured to identify at least one content for display on a content page using the matching identification entry.

Abstract: A method and a system that identify seller ads to potential buyers within a network-based commerce system are provided. The method and system may operate to receive a request including a product identification and financial metrics from a seller, and assign to the seller, based on a distance function and the product identification, a matching identification entry included in a set of identification entries. The method and system may further include operations to identify one or more seller ads associated with the matching identification entry, as determined by a relevance function based on the financial metrics and a distance measured between the matching identification entry and at least one extracted identification entry extracted from a selected content page and included in the set of identification entries.
