Web 3.0




Web 3.0 is a term that has been coined with different meanings to describe the evolution of Web usage and interaction along several separate paths. These include transforming the Web into a Database , a move towards making content accessible by multiple non-browser applications, the leveraging of Artificial Intelligence technologies, the Semantic Web , the Geospatial Web , or the 3D Web .


HISTORY

The term Web 3.0 first appeared prominently in early 2006 in a blog article by Jeffrey Zeldman critical of Web 2.0 and associated technologies such as Ajax .Jeffrey Zeldman Web 3.0 , ''A List Apart (Blog)'', January 16, 2006

At the Technet Summit in November 2006 , Jerry Yang , founder and Chief of Yahoo , stated

At the same Technet Summit, Reed Hastings , founder and CEO of Netflix , stated a simpler formula for defining the phases of the Web:

The term Web 3.0 became a subject of increased interest and debate from late 2006 extending into 2007.

WEB 3.0 DEBATES

There is considerable debate as to what the term Web 3.0 means, and what a suitable definition might be.


Transforming the Web into a database

The first step towards a "Web 3.0" is the emergence of "The Data Web" as structured data records are published to the Web in reusable and remotely queryable formats, such as XML, RDF and microformats. The recent growth of SPARQL technology provides a standardized query language and API for searching across distributed RDF databases on the Web. The Data Web enables a new level of data integration and application interoperability, making data as openly accessible and linkable as Web pages. The Data Web is the first step on the path towards the full Semantic Web. In the Data Web phase, the focus is principally on making structured data available using RDF. The full Semantic Web stage will widen the scope such that both structured data and even what is traditionally thought of as unstructured or semi-structured content (such as Web pages, documents, etc.) will be widely available in RDF and OWL semantic formats.

An evolutionary path to artificial intelligence

Web 3.0 has also been used to describe an evolutionary path for the Web that leads to Artificial Intelligence that can reason about the Web in a quasi-human fashion. Some skeptics regard this as an unobtainable vision. However, companies such as IBM and Google are implementing new technologies that are yielding surprising information such as making predictions of hit songs from mining information on college music Web sites. There is also debate over whether the driving force behind Web 3.0 will be intelligent systems, or whether intelligence will emerge in a more organic fashion, from systems of intelligent people, such as via Collaborative Filtering services like Del.icio.us , Flickr and Digg that extract meaning and order from the existing Web and how people interact with it.


The realisation of the Semantic Web and SOA

Related to the artificial intelligence direction, Web 3.0 could be the realization and extension of the Semantic Web concept. Academic research is being conducted to develop software for reasoning, based on Description Logic and Intelligent Agents . Such applications can perform logical reasoning operations using sets of rules that express logical relationships between concepts and data on the Web. Phil Wainewright What to expect from Web 3.0 , ''ZDNet'', November 29, 2005

Sramana Mitra differs on the viewpoint that Semantic Web would be the essence of the next generation of the Internet and proposes a formula to encapsulate Web 3.0. Sramana Mitra Web 3.0 = (4C + P + VS) , February 14, 2007

Web 3.0 has also been linked to a possible convergence of Service-oriented Architecture and the Semantic Web .Lee Provoost, Erwan Bornier , ''University of Utrecht'', February 10, 2006


Evolution towards 3D

Another possible path for Web 3.0 is towards the 3 dimensional vision championed by the Web3D Consortium . This would involve the Web transforming into a series of 3D spaces, taking the concept realised by Second Life further.Andrew Wallenstein Hollywood hot for Second Life , ''The Hollywood Reporter'', Feb 13, 2007 This could open up new ways to connect and collaborate using 3D shared spaces.Terri Wells Web 3.0 and SEO , ''Search Engine News'', November 29, 2006


Proposed expanded definition

Nova Spivack has proposed expanding the definition of Web 3.0 to include the convergence of several major complementary technology trends that are reaching new levels of maturity simultaneously including:
