9.4 Applications and Web 3.0 

It refers the evolution of web utilization and interaction which includes altering the Web into a  database. In enables the upgradation of back-end of the web, after a long time of focus on the front end (Web 2.0 has mainly been about AJAX, tagging, and another front-end user-experience  innovation). Web 3.0 is a term which is used to describe many evolutions of web usage and  interaction among several paths. In this, data isn’t owned but instead shared, where services show  different views for the same web / the same data. 

The Semantic Web (3.0) promises to establish “the world’s information” in more reasonable way  than Google can ever attain with their existing engine schema. This is particularly true from the  perspective of machine conception as opposed to human understanding. The Semantic Web  necessitates the use of a declarative ontological language like OWL to produce domain-specific  ontologies that machines can use to reason about information and make new conclusions, not  simply match keywords. 

Below are 5 main features that can help us define Web 3.0: 

1. Semantic Web 

The succeeding evolution of the Web involves the Semantic Web. The semantic web improves  web technologies in demand to create, share and connect content through search and analysis based  on the capability to comprehend the meaning of words, rather than on keywords or numbers. 

2. Artificial Intelligence 

Combining this capability with natural language processing, in Web 3.0, computers can distinguish  information like humans in order to provide faster and more relevant results. They become more  intelligent to fulfil the requirements of users. 

3. 3D Graphics 

The three-dimensional design is being used widely in websites and services in Web 3.0. Museum  guides, computer games, ecommerce, geospatial contexts, etc. are all examples that use 3D  graphics. 

4. Connectivity 

With Web 3.0, information is more connected thanks to semantic metadata. As a result, the user  experience evolves to another level of connectivity that leverages all the available information.

5. Ubiquity 

Content is accessible by multiple applications, every device is connected to the web, the services  can be used everywhere
