Generations of web 1.0, 2.0 and 3.0
- 1. The world wide web is larger collection of interconnected Documents or Content. Facilitates communication between people and also computers. Web based on Hypertext. Also based on client/server model The Internet is the collection of interconnected computer Networks. World Wide Web ≠ Internet Service We must remember that both are not the same. Web is different then Internet. WEB INTERNET
- 2. WEB 1.0 (Past) WEB 2.0 (Present) WEB 3.0 (Future) Web 1.0 was referred as the first generation of World Wide Web which was basically defined as- “It is an information space in which the items of interest referred to as resources are identified by global identifier called as Uniform Resources Identifiers (URIs)”. First stage of the World Wide linking web pages and hyperlink Most read-only Web. It focused on companies home pages Dividing the world wide web into usable directories It means Web is use as “Information Portal”. Everyone has their personal own little corner in the cyberspace It started with the simple idea Tim O’Reilly defines web 2.0 on his website as follows- “Web 2.0 is the business revolution in the computer industry caused by the move to the internet as platform, and an attempt to understand the rules for success on that new platform. Chief among those rules is this: Build applications that harness network effects to get better the more people use them.” It is a platform that gives users the possibility (liberty) to control their data. This is about user-generated content and the read-write web. People are consuming as well as contributing information through blogs or sites like Flicker, YouTube, Digg, etc. Web 3.0 is one of modern and evolutionary topics associated with the following initiatives of Web 2.0. Web 3.0 was first coined by John Markoff of the New York Times and he suggested web 3.0 as third generation of the web in 2006. Web 3.0 can be also stated as- “executable Web”. Semantic Web • It is a Web of data. • changing the web into a language that can be read and categorized by the system rather then humans. • An idea of more meaningful web where resource discovery will be assisted by intelligent agents. Artificial Intelligence • Extracting meaning from the way people interact with the web.
- 3. Generations of WEB 1.0 Content • Personal websites. • Content destination sites. Search • Critical mass of content drives need for search engines. Commerce • Commerce goes Mainstream. • Digital goods rise.
- 4. Generations of WEB 2.0 Speedy • More timely information. • More efficient tools to find information. Collaborative • At the same time in different places. Trust-worthy • Users establish trust Networks. • Government use the Web
- 5. Generations of WEB 3.0 Ubiquitous Available anytime, anywhere, through any channel or device. Individualized Filtered and shared by friends or trust networks. Efficient Relevant and contextual information findable instantly.

- 7. Limitations- The major limitations of Web 1.0 are as follow:- • The Web 1.0 pages can only be understood by humans (web readers) they do not have machine compatible content. • The web master is solely responsible for updating users and managing the content of website. • Lack of Dynamic representation i.e., to acquire only static information, no web console were available to performing dynamic events. The major limitations of Web 2.0 are as follow:- • Constant iteration cycle of Change and Updates to services. • Ethical issues concerning build and usage of Web 2.0. • Interconnectivity and knowledge sharing between platforms across community boundaries are still limited. The major limitations of Web 3.0 are as follow:- • Vastness: The World Wide Web contains many billions of pages. Redundancy in Data may occur which has not yet been able to eliminate all semantically duplicated terms. • Vagueness: This arises from the vagueness of user queries, of concepts represented by content providers, of matching query terms to provider terms and of trying to combine different knowledge bases with overlapping but subtly different concepts. • Deceit: This is when the producer of the information is intentionally misleading the consumer of the information.
- 8. Types of WEB 1.0 applications are:- • static web sites • personal sites. Types of Web 2.0 applications are:- • Collaborative Web Tools –Wikipedia, Drupal, Joomla, Blog, Trac, Bugzilla etc. • Interactive Web Tools – Gtalk, Yahoo Chat, GoogleDoc, Picasa, Flickr • Social Networking Tools- Orkut, Facebook, Twitter, WhatsApp etc. • Information Mashup – Google Map, Indiarailinfo, etc. Types of Web 2.5 applications are:- • Amazon • Google Types of Web 3.0 applications are:- • Apple’s Siri • Google Cloud API
- 9. Four design essentials of a Web 1.0 site include: Static pages. Content is served from the server’s file-system. Pages built using Server Side Includes or Common Gateway Interface (CGI). Frames and Tables used to position and align the elements on a page.
- 10. Development of Web 2.0 technologies:- Users’ Participation A user can express their feelings and view about the content. They can agree or disagree with the source. This participation leads in collaboration and development of innovative thoughts. User centric services The user may keep changing their priorities and services options and the services have to stand themselves to each call of their users. Decentralization and Interoperability The service nodes generate services in a standard format, which can be amalgamated to a single service. This makes systems interoperable over a federated environment. Hiding technological complexity The technology is developed in such a way that users need not bother about the hassles of technology rather they should concentrate on content of the services. The technology is kept hidden from the user. Modularity Modules are components of any system. Modular approach towards a system provides flexibility for adding or removing any feature out of the system. In Web 2.0, the modularity provides facility to add or remove components offering flexibility to a great extent.
- 11. Key Elements of Web 3.0 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. 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. 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. 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. The Media Centric Web According to media centric web approach ,in near future search engines are able to take media such as audio, video, image etc as an input element and be able to search for similar media
- 12. Conclusion The web offers so many opportunities to people with disabilities that are unavailable through any other medium. It offers independence and freedom. However, if a web site is not created with web accessibility in mind, it may exclude a segment of the population that stands to gain the most from the internet. The Semantic Web (Web 3.0) promises to “organize the world’s information” in a dramatically more logical way than Google can ever achieve with their current engine design. o knowledge of all kinds gets represented in a form that is interpretable both by people and machines. o different forms of language in which knowledge is expressed begin to be interrelated and made interchangeable with each other. o when knowledge is encoded in a semantic form, it becomes transparent and accessible at any time to a variety of reasoning engines.
