Standardization for Semantic Web in the context of Web 3.0 is under the care of W3C. Components. The term Semantic Web is often used more specifically to refer to the formats and technologies that enable it. 1  The collection, structuring and recovery of linked data are enabled by technologies that provide a formal description of concepts, terms, and relationships within a given knowledge domain.
I think the lesson of the last five years is semantic is a feature, not a product space. Yahoo was first with significant/useful semantic search feature (SearchMonkey), then Google and Bing added the similar functionality. Facebook is recently doing a lot of stuff in semantic space (Open Graph, likes, Facebook Connect), etc.
