Web 3.0 is slated to be the new paradigm in web interaction and will mark a fundamental change in how developers create websites, but more importantly, how people interact with those websites. Computer scientists and Internet experts believe that this new paradigm in web interaction will further make people's online lives easier and more intuitive as smarter applications such as better search functions give users exactly what they are looking for, since it will be akin to an artificial intelligence which understands context rather than simply comparing keywords, as is currently the case.
Web 3.0 will be a complete reinvention of the web, something that Web 2.0 was not. Web 2.0 was simply an evolution from the original Web which can be compared to a library, as Web 1.0 was essentially an infodump, a place where people just placed walls upon walls of text which people can read but usually not interact with. Web 2.0 changed this by allowing user interaction with dynamic websites that acted more as applications than simply pages of information.
There is no concrete definition for Web 3.0 yet and the technology that will bring us there has not even matured yet. So to get a better understanding of Web 3.0, let us look at an example. In the current Web 2.0, users can interact with websites that have predetermined behaviors according to the input of users. Users can search for information using various search engines which generally provide satisfactory results if there is enough information regarding the search. However, that search is only for keywords and brings in the most popular information available, and does not understand the context of the search. So if a user searches for an insect called a camaro and uses only that one word, then about 90 percent of the search results are for the Chevy Camaro model of car and not the insect because the car is the most popular search result and has the most prolific information. However, Web 3.0 will be able to get the context from the user; and then be able to provide the user with the most useful information about the camaro insect, such as its habitat and even where to find it as a delicacy. Web 3.0 can be likened to an artificial intelligence assistant that understands its user and personalizes everything.
Furthermore, if someone is preparing for a vacation and needs to search for cheap flights and accommodations as well as meals, they must look through a lot of information on the web comparing different selections and the search might take hours. But Web 3.0 search engines or assistants will be able to scrape all of this information and present it to the user in a very intelligent way, even making highly accurate and favorable suggestions based on the user's profile.
