Web 2.0

Web 2.0 is the “original” web as most people know it. This is the style that became standard in the late 1990s, and includes all the features that have allowed web pages to move beyond static documents. Although there was no formal technical specification by the World Wide Web Consortium, Web 2.0 marked a cultural shift in how web pages were developed, designed, and used. It saw the meteoric rise of social media, including Facebook and Twitter, and user-generated content such as blogs, wikis—Wikipedia being perhaps the most famous—and video sharing sites such as YouTube. It has also been linked with a particular visual style that includes the use of gradients, colorful icons, reflections, drop shadows, and large text, many of which were collected in design tutorials and the like.

The DarkNote WordPress theme from ThemeForest is a great example of Web 2.0. It showcases Web 2.0 styling both visually and from a technology standpoint. Visually, it relies heavily on images, background textures, drop shadows, and gradients; meanwhile WordPress, the CMS offering the theme is one of the most popular Web 2.0 technologies. WordPress allows users to quickly create a blog that not only contains their own user-generated content, but others’ as well, via comments. WordPress also allows users to easily link to other Web 2.0 mainstays, including YouTube, Wikipedia, Pinterest, Twitter, and Facebook.

Web 3.0

Web 3.0, or the Semantic Web, is the web era we are (arguably) currently in, or perhaps the era we are currently creating. Web 3.0, with its use of semantics and artificial intelligence is meant to be a “smarter web”—one that knows what content you want to see and how you want to see it so that it saves you time and improves your life.

The only problem is that not everyone agrees on whether it exists yet! In his article, What is Web 3.0?, Daniel Nations nicely overviews the various components of what people predict Web 3.0 will be, including a web that is semantic, artificially intelligent, virtual, and ever-present. There is a lot of work being done on all four of these fronts. Content Management Systems (CMSs) and search engines are working hard to make the web more semantic; governments, corporations, and universities are racing to make artificial intelligence and virtual reality a, well, reality; and the ever-present aspect of the web shows in our dependency on smart phones, tablets, and wearables. Let’s not forget about the shift in visual design! While there isn’t an official Web 3.0 visual design guide, users tend to identify the tenets of Web 2.0 with outdated sites, and designers are opting instead for what has been called “flat design,” which champions minimalism and usability.

While Web 3.0 is far from ubiquitous, and the technology is still coming into fruition, its styles are popping up everywhere—we’ve all seen and recognized them. These are the sites that are using taxonomies to improve search, personalization to serve up pertinent content, and flat design to improve the readability and usability of the site. One such example is The Boston Globe’s site Boston.com, known for its personalization efforts, which are laid out in the Boston.com Recommendations FAQs.

Web 2.0 uses the read write web,blog,web application or Folksonomy while sharing the content and focusing on communities. Besides, Web 3.0  uses the semantic web, drag n drop mash ups, widgets, user behavior or Me-onomy, advertisement, user engagement, consolidates dynamic content and focuses on individuals.

Web 2.0  is the second stage of development of Internet, in web 2.0 we focus more on user generated data and make world wide Web more interactive . the term first coind in first web 2.0 summit around 2004 . the second generation of world wide web includes various tools and platform to enable user generated web and more dynamic in nature.various social platefom and wiki came In this stage of world wide web which allow more interlinked and more attractive web site . In this stage the participation of user in world wide increase comprehensively and hence created fast amount of user generated data. Web2.0 is not a technological spesifiation but it simply defiend new type of content driven website.

WEB 3.0

Web 3.0 is the third stage of development of the world wide web its comrises a semantic web which shows the semantic nature of the content. Tim Berners Lee coined the term semantic web which means that the data on the web gives more realistic detail about the topic and it relate with real situation . in semantic web web browser act as personal assistance, to understand this I give an example . suppose you want to watch movies and after watching movie you want to eat spicy chicken and then u also u want to test ice cream , so in this scenario you normally search the nearest movie theater on the internet and then you search for best chicken shop near you and in the last you search for ice cream shop. For doing this you normally visit 3 to 4 web site for each and then finally you decide that where you should watch movie or eat chicken. So the whole process become hectic and time consuming , the solution of this problem is this if  your web browser knows the like and dislike of your choice and also your location then based on your daily behavior browser can suggest you that where to watch movie and where you eat chicken . so in this way your browser act as your  personal assistant which will guide you .

If we search some keyword in search engine the search engine give the link of the website according to that keyword which is purely based on indexed web pages with related to that keyword . the search engine do not no meaning of that keyword in real life situation as we human do they simpllly treat it as string of character. So in web 3.0 the Developer engineer and linguistic scientist are trying to build algorithmic tool to solve this problem, for web3.0 new web languages and new standard need to be develop to encounter these challenges.

Differences between the web 2.0 and the web 3.0:

Web 2.0 - It is the “writable” phrase of the World Wide Web with interactive data. Web 2.0 facilitates interaction between web users and sites, so it allows users to interact more freely with each other. Web 2.0 encourages participation, collaboration, and information sharing. Examples of Web 2.0 applications are FB. Twitter, Youtube, wiki.

Web 3.0 -  It is the “executable” phrase of Word Wide Web with dynamic applications, interactive services, and “machine-to-machine” interaction. Web 3.0 is a semantic web which refers to the future. In Web 3.0, computers can interpret information like humans and intelligently generate and distribute useful content tailored to the needs of users. One example of Web 3.0 is Tivo, a digital video recorder. Its recording program can search the web and read what it finds to you based on your preferences.

Web 2.0 uses the read write web, blogs, web applications, rich media, viral media, tagging or Folksonomy while sharing content and focusing on communities.

The Web 3.0 standard uses semantic web, drag n drop mash ups, widgets, user behavior or Me-onomy, advertisement, user engagement, consolidates dynamic content and focuses on individuals.

Web 3.0 uses the ‘Data Web’ technology featuring structures data records that are publishable and reusable on the web through query-able formats like RDF, XML and micro formats. It is the stepping-stone to complete semantic web, which enables new levels of application operability, data integration and makes data openly linkable and accessible in the form of web pages. The complete semantic web stage expands the scope of both structured and un-structured content through OWL and RDF semantic formats.

The web 3.0 standard also describes the latest trends for artificial intelligence. Mass level use of technology is promptly visible here as in the case of an application that makes hit song predictions based on music websites of various colleges available on the net. Web 3.0 aims to highlight intelligence in an organic fashion through the interaction of people.

Can web 3.0 extend itself to the semantic web concept using artificial intelligence? There is plenty on ongoing research to develop software, which uses reasoning based on intelligent agents and description logic. These applications perform all logical and reasoning operations using the set of rules, which expresses logical relationship between the data on the net and their concepts.

for example,  A typical web 2.0 app may use online knowledge community, which involves people tagging of content and its categorization. On the other hand, web 3.0 app uses content management systems along with artificial intelligence. These systems are capable of answering your questions because it can think on its own and find the most probable answer to the query. This signifies that web 3.0 can also be termed as “machine to user” standard.
