The Concept Web is a collaborative movement led by the Concept Web Alliance to create a new Web separable from the previous Web layer (Web 2.0) that is computable by mechines. For e.g. "what museums are open around here tomorrow?" That question requires a level of machine intelligence that knows what a museum is, you're location, the museum hours, and what day of the week it is right now. Search engines aren’t good at that, because they’re too messy. Questions in a search engine have many answers, with varying degrees of applicability and “rightness.” That’s not computable, not clean enough to program or feed into a system.
The Concept Web is a new type of Web composed of Concept Web platforms with these Web platforms functionng as a central nervous system. This Web will give rise to mobile software agents (virtual assistants) that can perform tasks, or services for an individual based on user input, location awareness, and the ability to access information from a variety of online sources. For the old Web stay to relevant, a lot of proprietary systems need access to each other’s APIs and some new coherence language, and history has shown large technology companies tend to protect their own patch.
