DBpedia is the
semantic version of the popular Wikipedia. It is a Crowd-Sourced community effort to extract structured Information from Wikipedia and to make this Information availability on the Web. DBedia allows to make sophisticated Queries against Wikipedia, and to link to other Datasets on the Web to Wikipedia Data.
Many pages are created in the same way. There are templates for certain classes like persons that always provide the same fields. This Information is somehow structured information. It is very simple to extract this structured information and to connect the single parts of the structured information with corresponding Knowledge Representation that gives us a clue about the Meaning of these Properties. All the Facts are expressed with the help of a Language that can by read by machines, namely RDF, the Resource Description Framework.
Amazon provides the possibility to connect Amazon Web Services to DBpedia [http://aws.amazon.com/datasets/2319?_encoding=UTF8&]jiveRedirect=1].
