Definition
The semantic web is a technological approach to making it easier to exchange data between information systems, using not only Web technologies, but also the use of shared agreements (as established by schemata, ontologies and logic) to facilitate some of the automated aspects of the knowledge exchange.
The semantic web makes information directly readable by machines, without necessarily passing through human interpretation.
Discussion
W3C explanation
From the W3C at http://www.w3.org/2001/sw/
"The Semantic Web is a web of data. There is lots of data we all use every day, and its not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar. But can I see my photos in a calendar to see what I was doing when I took them? Can I see bank statement lines in a calendar?
Why not? Because we don't have a web of data. Because data is controlled by applications, and each application keeps it to itself.
The Semantic Web is about two things. It is about common formats for interchange of data, where on the original Web we only had interchange of documents. Also it is about language for recording how the data relates to real world objects. That allows a person, or a machine, to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing." (http://www.w3.org/2001/sw/)
Explanation 2
"Berners-Lee defines the Semantic Web as “a web of data that can be processed directly and indirectly by machines.”
In the Semantic Web data itself becomes part of the Web and is able to be processed independently of application, platform, or domain. This is in contrast to the World Wide Web as we know it today, which contains virtually boundless information in the form of documents. We can use computers to search for these documents, but they still have to be read and interpreted by humans before any useful information can be extrapolated. Computers can present you with information but can’t understand what the information is well enough to display the data that is most relevant in a given circumstance. The Semantic Web, on the other hand, is about having data as well as documents on the Web so that machines can process, transform, assemble, and even act on the data in useful ways."
