A Domain Ontology Oriented Resource System (DOORS) and a Problem Oriented Registry of Tags And Labels (PORTAL) are infrastructure systems for resource metadata within a paradigm serving as a bridge between the original web and the semantic web. IRIS registers domain names while DNS publishes domain addresses with mapping of names to addresses for the original web. Analogously, PORTAL registers resource labels and tags while DOORS publishes resource locations and descriptions with mapping of labels to locations for the semantic web. They provide an analogous resource label system, semantic search applications, and the benefits of collaborative semantic networks. Advertising is supported in several ways. Businesses purchase the right to display their products or services in association with searches. Also, content providers accept placement of advertising. Ads are then selected for display based on the content displayed utilizing the invention to match service providers with advertisers.
