Semantic Web

A distributed collection of "linked data" on the Web. Just as Web pages are linked together via hypertext, the goal of the Semantic Web is to ultimately link all the available public data.

Sometimes called "Web 3.0," the purpose of the Semantic Web is to make searches more effective. As information has grown exponentially on the Web, search engines routinely return countless result links when, very often, only one or two items of data are required to answer a query. Wading through the articles has turned people into research analysts whether they were ready for the task or not.

More Summaries Than Before
One cannot help but notice that results from search engines increasingly deliver a concise summary of facts about the subject of the query in addition to the Web page links. These summaries are derived from semantic-oriented knowledge bases.

URIs and RDF Models
The Semantic Web uses URIs to identify the data, the RDF data model to structure the relationships and numerous ontological vocabularies that provide the definitions. See ontology, URI, RDF, semantic browser and semantic search.

Who's Developing the Semantic Web?
Knowledge bases structured with semantic meaning are continuously being developed by government and private industry as well as community driven. At some point, Google's knowledge base may wind up being the world's largest (see Google Knowledge Vault). See virtual assistant, Wikidata, Freebase and DBpedia.

While the public sphere is in the midst of a "revolution" from "Web 1.0" technologies to those of Web 2.0 (blogs, wikis, folksonomies and other forms of interactivity and social networks), corporations are awaiting further evolution of the semantic web and semantic web services (which can be considered Web 2.0 for the corporate sphere in some respects).
As Wolfgang Ernst (2013) put it, we live in an era of dynamic archives--the usage of content generates metadata that recontextualizes resources, and thus all triples in semantic networks also can be updated and modified in the process--and the Semantic Web is dynamic due to the data exhaust.
The move to a web of linked data was catalysed when in 2001, Tim Berners-Lee (the inventor of the web), James Hendler and Ora Lassila first published their new vision for 'The Semantic Web' in an article for the Scientific American.

On the other hand, it is said that Microformats are usable, unlike Semantic Web robust technologies (Khare, 2006); these may not be such complex, but right there is its strength, because of its simplicity, these ones are easy to use for final users, who must index its resources on Web.

To remedy the data integration issues of the traditional web mashups, the semantic web technology uses the Linked Data based on RDF data model as the unified data model for combining, aggregating, and transforming data from heterogeneous data resources to build Linked Data mashups.
