Abstract

Directory assistance provides telephone number look up services to callers based on the business or caller name as listed in a telephone directory. In the prior art, directory assistance provides a value-added service to telephone users and an expense that must be charged back to telephone users or absorbed by telephone carriers. In enhanced directory assistance (EDA) services as described in the disclosure, EDA is further developed to deliver a keyword targeted advertising service to telephone listing owners and advertisers. The present invention provides a method and system to publish and distribute advertised listings to multiple EDA service providers in a collaborative marketplace. A further object of the invention is to provide methods and systems that increase competition for the most sought-after business keyword categories and provide near-realtime maintenance and placement provisioning for location-based products and services.
