'''Web 3.0''' is one of the terms used to describe the evolutionary stage of the [[World Wide Web|Web]] that follows [[Web 2.0]]. Given that technical and social possibilities identified in this latter term are yet to be fully realized the nature of defining Web 3.0 is highly speculative. In general it refers to aspects of the Internet which, though potentially possible, are not technically or practically feasible at this time.
==History==
The term Web 3.0 became a subject of increased interest and debate from late 2006 extending into 2007.
 
==DefinitionsOrigin andof roadmapthe term==
Following the introduction of the phrase "[[Web 2.0]]" as a description of the recent evolution of the Web, the term "Web 3.0" has been introduced to hypothesize about a future wave of Internet innovation. Views on the next stage of the World Wide Web's evolution vary greatly, from the concept of emerging technologies such as the [[Semantic Web]] transforming the way the Web is used (and leading to new possibilities in [[artificial intelligence]]) to the observation that increases in Internet connection speeds, modular [[web applications]], and advances in [[computer graphics]] will play the key role in the evolution of the World Wide Web. <ref>[http://student.bmj.com/issues/08/03/editorials/095.php Dean Giustini. Web 3.0 and Medicine. British Medical Journal. December 2007.]</ref>
There is considerable debate in both the IT industry and blogging communities about whether Web 3.0 is a valid entity, and what it actually is. It is suggested by many that the term is just another [[buzzword]], while the contrary view is that it as an evolutionary path for the Web as depicted by the following phases:
 
===Proposed expanded definition===
* [[Web 1.0]]: [[Web Browser]] driven "Interactive Web of Hypertext" pages where presentation, logic, and data are indistinguishable
Web 3.0, a phrase coined by [[John Markoff]] of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called 'the intelligent Web'—such as those using semantic web, microformats, natural language search, [[data mining]], machine learning, recommendation agents, and artificial intelligence technologies—which emphasize machine-facilitated understanding of information in order to provide a more productive and intuitive user experience.
* [[Web 2.0]]: Web Services based [[API]] driven "Web of Services" that separate "[[Application Logic]]" from the erstwhile intermingled presentation, logic, and data pages of [[Web 1.0]]. Examples of [[Web 2.0]] application profiles include: [[blogs]], [[wikis]], the use of [[Ajax (programming)|Ajax]] to improve web application interaction richnes, and [[Mashup (web application hybrid)|mashups]]. Web 2.0 does not explicitly expose [[Data Model]]s.
* '''Web 3.0''': The final step in the decomposition of monolithic Web Pages into discrete components that include: Presentation (HTML and (X)HTML), Logic (Web Services APIs), and Data (Data Models) trinity that transitions Web Data containment from Web Pages to Web Data. It's emergence simplifies the development and deployment of Data Model driven [[composite applications]] that provide easy, transparent and organized access to “the world’s data, information, and knowledge”{{Fact|date=February 2007}}<br/>.
 
[[Nova Spivack]] defines Web 3.0 as the third decade of the Web ([[2010s|2010–2020]]) during which he suggests several major complementary technology trends will reach new levels of maturity simultaneously including:
If you look at Web interaction through the lenses of the popular [[MVC|M-V-C]] pattern, then Web 3.0 is the "M" where Web 2.0 is the "C" and Web 1.0 the "V".

==Research==
{{cquote|Digital information about nearly every aspect of our lives is being created at an astonishing rate. Locked within all of this data is the key to knowledge about how to cure diseases, create business value, and govern our world more effectively. The good news is that a number of technical innovations ([[RDF]] which is to data what HTML is to documents, and the [[Web Ontology Language]] (OWL) which allows us to express how data sources connect together) along with more openness in information sharing practices are moving the World Wide Web toward what we call the Semantic Web. Progress toward better data integration will happen through use of the key piece of technology that made the World Wide Web so successful: the link. The power of the Web today, including the ability to find the pages we're looking for, derives from the fact that documents are put on the Web in standard form, and then linked together. The Semantic Web will enable better data integration by allowing everyone who puts individual items of data on the Web to link them with other pieces of data using standard formats.
===Research under Spivack's definition===
====Transformation====
 
Web 3.0 has been described as the "executable web". In the analogy to [[file system permissions]], Web 1.0 was "read-only", Web 2.0 is "read-write", and Web 3.0 will be "read-write-execute". <ref>http://www.britannica.com/blogs/2007/07/web-30-the-dreamer-of-the-vine/</ref> With the still exponential growth of computer power, it is not inconceivable that the next generation of sites will be equipped with the resources to run user-contributed code on them.{{Fact|date=September 2007}} The "executable web" can morph online applications into [[Omni Functional Platform]]s that deliver a single interface rather than multiple nodes of functionality.<ref name="Wainewright,2005" >{{cite web
To appreciate the need for better [[data integration]], compare the enormous volume of experimental data produced in commercial and academic drug discovery laboratories around the world, as against the stagnant pace of drug discovery. While market and regulatory factors play a role here, life science researchers are coming to the conclusion that in many cases no single lab, no single library, no single genomic data repository contains the information necessary to discover new drugs. Rather, the information necessary to understand the complex interactions between diseases, biological processes in the human body, and the vast array of chemical agents is spread out across the world in a myriad of [[database]]s, [[spreadsheet]]s, and [[document]]s.

====Network computing====
Scientists are not the only ones who need better data integration. Consider the investment and finance sector, a marketplace in which profit is generated, in large part, from having the right information, at the right time, and reaching correct conclusions based on analysis and insight drawn from that information. Successful investment strategies are based on finding patterns and trends in an increasingly diverse set of information sources (news, market data, historical trends, commodity prices, etc.). Leading edge financial information providers are now developing services that allow users to easily integrate the data they have, about their own portfolios or internal market models, with the information delivered by the information service. The unique value creation is in the integration services, not in the raw data itself or even in the software tools, most of which will be built on open source components.
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]], for example, the ''World Wide Mind'' project.<ref>[http://www.w2mind.org/ World Wide Mind project]</ref> Such applications can perform logical reasoning operations using sets of rules that express logical relationships between concepts and data on the Web.<ref name="Wainewright,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.<ref name="Mitra,2007" >{{cite web

====Distributed databases====
New data integration capabilities, when directed at personal information, pose substantial privacy challenges which are hardly addressed by today's privacy laws. The technology of today's Web already helps reveal far more about individuals, their behavior, their reading interest, political views, personal associations, group affiliations, and even health and financial status. In some cases, this personal information is revealed by clever integration of individual pieces of data on the Web that provide clues to otherwise unavailable information. In other cases, people actually reveal a lot about themselves, but with the intent that it only used in certain contexts by certain people. These shifts in the way we relate to personal information require serious consideration in many aspects of our social and legal lives. While we are only just beginning to see these shifts, now is the time to examine a range of legal and technical options that will preserve our fundamental privacy values for the future without unduly stifling beneficial new information processing and sharing capabilities. Our research group at MIT is investigating new technologies to make the most of the Semantic Web, as well as both technical and public policy models that will help bring increased transparency and accountability to the World Wide Web and other large scale information systems.[8] Our belief is that in order to protect privacy and other public policy values, we need to research and develop new technical mechanisms that provide great transparency into the ways in which information in the system is used, and provide accountability for those uses with respect to what ever are the prevailing rules.|20px|20px|[[Tim Berners-Lee]]}}
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]], [[Resource Description Framework|RDF]], [[Website Parse Template]] and [[microformats]]. This is also known as the bottom-up approach.<ref name="LCI1" >{{cite web

}}</ref> 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.

==Web 3.0 Debates==
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.<ref name="Markoff1"/>
 
===Other potential research===
There is considerable debate as to what the term Web 3.0 means, and what a suitable definition might be{{fact|date=March2007}}.
====3D spaces====
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.<ref name="Wallenstein,2007" >{{cite journal

====Socio-technological research====
Nova Spivack has proposed that an objective way to define Web 3.0 might be as "the third decade of the Web, from 2010 to 2020". Spivack suggests that Web 2.0 has largely been focused on front-end user-interface improvements such as AJAX, while Web 3.0 will shift the focus back to the backend - the underlying technologies of the Web, enabled by Semantic Web technologies. In Spivack's view, Web 3.0 will begin by transforming the Web into a database -- what some call the Data-Web using RDF and SPARQL. The next step after that will be the addition of richer semantics, using OWL. By 2030, Spivack predicts the Semantic Web will be globally integrated into the Web, opening the door for the fourth decade of the Web, Web 4.0 to begin, in which the focus will shift back to the front-end again, with a new generation of more intelligent applications and services that interact with users, assist them, and help them to use the Web more productively..<ref>Nova Spivack [http://novaspivack.typepad.com/nova_spivacks_weblog/2007/02/steps_towards_a.html How the WebOS Evolves?], February 09, 2007</ref>
 
The inclusion of the concept of a "Web 0.0" as the pre-existing real-world "sensual web" has been proposed. In that context Web 3.0 is the development of a series where integration of technologies for digital networking and processing is digested and non dissociable of the new "real-world". In this definition, Web 3.0 is "the biological, digital analog web where information is made of a plethora of digital values coalesced for sense and linked to the real-world by analog interfaces."<ref name="Zand,2006" >{{cite web
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 considerable research taking place in academia and governments around the world to develop [[reasoners]] that can reason on Semantic Web data-sets. In addition, research has been taking place for decades on the subject of [[intelligent agents]] which can roam the Web and enact procedures on behalf of end-users and applications in an intelligent fashion. 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. <ref>John Markoff, [http://www.nytimes.com/2006/11/12/business/12web.html?pagewanted=1&ei=5088&en=254d697964cedc62&ex=1320987600 Entrepreneurs See a Web Guided by Common Sense], ''[[New York Times]]'', November 12, 2006</ref>

But if I were to guess what Web 3.0 is, I would tell you that it's a different way of building applications... My prediction would be that Web 3.0 will ultimately be seen as applications which are pieced together. There are a number of characteristics: the applications are relatively small, the data is in the cloud, the applications can run on any device, PC or mobile phone, the applications are very fast and they're very customizable. Furthermore, the applications are distributed virally: literally by social networks, by email. You won't go to the store and purchase them... That's a very different application model than we've ever seen in computing.|[[Eric Schmidt]]}}
