As we learned from What is Web 3.0?, there are some common traits being identified for the various definitions of what a Web 3.0 application should be. People use a similar term called "Semantic Web" for Web 3.0, which is described as being able to interpret user input and tailor the web surfing experience to make it more relevant and personal.
However, there are subtle but critical differences between various versions of the Web 3.0 solutions. One major trend falls into the "Semantic Web" concept coined by Tim Berners-Lee, the inventor of the World Wide Web and the director of the World Wide Web Consortium (W3C).
According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries."
The Semantic Web provides a way to extend the network of hyperlinked human-readable Web pages by inserting machine-readable meta data about pages and how they are related to each other, enabling automated agents to access the Web more intelligently and perform tasks on the behalf of users. However, after it was originally proposed by Berners-Lee from 2001 to present, this has yet to happen as there are many critics concerning its feasibility and places a heavy burden on web masters, blog authors and web publishers to embed additional machine-readable meta data into billions of web pages that are designed to be read by people. It makes the tasks more time-consuming to create and publish content, as well as the possibility of misleading the meta-tags. It also adopts the common technologies and concepts of XML, XML schema and Ontology as Web Ontology Language (OWL), a family of knowledge representation languages.
Some existing Semantic Web implementation has proposed on-page marked-up categories as a collection of schema or ontologies with HTML tags along with descriptions that webmasters can use to mark-up their pages in ways recognized by major search engine providers to improve search results. For example, productontology.org provides ca. 300,000 precise definitions for types of product or services that extend the schema.org and GoodRelations standards for e-commerce mark-up. Another interesting service is provided by DBpedia which offers a very useful representation for the Semantic Web for the majority of the 3.5 million Wikipedia entries, but it does not provide valid OWL and it's lack of a suitable semantics for being used as classes as an RDF.
Google also announced support for the GoodRelations vocabulary for product and price information in Web pages. A product listing has a number of properties,
which you can mark-up using
RDFa. Due to the hassle of putting all the additional tags manually into each web page,
microformats are declared to lower the barrier for entry for the web site developers by encoding and extracting events, contact information, social
relationships and the like automatically and re-use existing HTML/XHTML tags to convey meta data and other attributes in web pages and other contexts
that support (X)HTML, such as RSS. Unfortunately, no new microformat specifications have been published since 2008 and no further movement is pushed
through at Google's site other than
hReview since then.
Furthermore, Tim Berners-Lee described the semantic web as a component of "Web 3.0". Some of the challenges for the Semantic Web include vastness, vagueness, uncertainty, inconsistency, and deceit. Automated reasoning systems will have to deal with all of these issues in order to deliver on the promise of the Semantic Web. Some experts point out that logic-based semantic web technologies cover only a fraction of the relevant phenomena related to semantics. Where Semantic Web technologies have found a greater degree of practical adoption, it has tended to be among core specialized communities and organizations for intra-company projects. The practical constraints toward adoption have appeared less challenging where domain and scope is more limited than that of the general public and the World Wide Web.
Therefore, instead of using machine-constructed semantic tags and algorithms, some people proposed to have human-constructed semantic standards and data, according to David Siegel's perspective in Pull: The Power of the Semantic Web, 2009. This book is described by GoodReads.com as:
"The first clear guide to the Semantic Web and its upcoming impact on the business world."
It is also introduced by WordCat.org:
"We are at the beginning of a new technology curve known as the Semantic Web that will affect all areas of business. This book shows which industries are already ahead, the power shift from pushing to pulling information, and how to plan your own strategy for embracing this new web."
