Web 3.0 is, among other things, about the Semantic Web and personalization.
The next generation of the Web is Web 3.0, will make tasks like your search faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. The browser will analyze your response, search the Internet for all possible answers, and then organize the results for you.The Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions. Eventually you might be able to ask your browser open questions like 'where should I go for lunch?' Your browser would consult its records of what you like and dislike, take into account your current location and then suggest a list of restaurants.
Conrad Wolfram has argued that Web 3.0 is where "the computer is generating new information", rather than humans.
"Web 3.0 - the Read-Write-Execute Web". Rajnish Sharma says, Web 3.0 is defined as the creation of high-quality content and services produced by gifted individuals with fater search technology & great reduction in exceution timeusing Web 2.0 technology as an enabling platform.
Futurist John Smart, lead author of the Metaverse Roadmap echoes Sharma's perspective, defining Web 3.0 as the first-generation Metaverse (convergence of the virtual and physical world), a web development layer that includes TV-quality open video, 3D simulations, augmented reality, human-constructed semantic standards, and pervasive broadband, wireless, and sensors. Web 3.0's early geosocial (Foursquare, etc.) and augmented reality (Layar, etc.) webs are an extension of Web 2.0's participatory technologies and social networks (Facebook, etc.) into 3D space. Of all its metaverse-like developments, Smart suggests Web 3.0's most defining characteristic will be the mass diffusion of NTSC-or-better quality open video to TVs, laptops, tablets, and mobile devices, a time when "the internet swallows the television." Smart considers Web 4.0 to be the Semantic Web and in particular, the rise of statistical, machine-constructed semantic tags and algorithms, driven by broad collective use of conversational interfaces, perhaps circa 2020. David Siegel's perspective in Pull: The Power of the Semantic Web, 2009, is consonant with this, proposing that the growth of human-constructed semantic standards and data will be a slow, industry-specific incremental process for years to come, perhaps unlikely to tip into broad social utility until after 2020.
