What is Artificial Intelligence involved in the Web 3.0?

It is said that implementing artificial intelligence in different web applications should be the next big thing and also one of the features of Web 3.0. Today, the results provided by Internet search engines make use of sophisticated software called crawlers. The results however, may not be exact enough to satisfy the users needs. The human element/quality of analyzing and grading a particular result to be useful can bring a sea change in the way quality information is provided to the user. The discrepancy or probably limitation of human beings manipulating or giving a biased opinion about a particular thing can also hamper this process at the same time. The need for implementation of artificial intelligence in making search engines more efficient could arise in the future and be one of the features of Web 3.0.
