A dramatic shift in business and technology is taking place as the Social Web (Web 2.0) evolves into the Semantic Web (Web 3.0) of the future. Networks link smartphones, in-car computers, televisions and home media networks to collectively provide instant and universal access to personal information and entertainment media. Integrated marketing campaigns feature an enticing mix of content and location-based and contextual-aware advertising delivered through digital signs and billboards. Highly targeted advertising is generated based digital profiles that describe the habits and preferences of an individual without revealing personal identifiable information, and then delivered through entertainment systems and mobile applications. Vast interconnected systems of distributed applications ingest data, generate feeds, and intelligently filter content based on usage patterns and preferences. This presentation, part one of three, covers the evolution of the Web, business models on the Web, and core elements of the semantic Web. Part two highlights existing products and systems that contain semantic Web elements. Part three covers 17 semantic Web application scenarios and forecasts the impact of Web 3.0 on marketing, advertising and business models.
