What is Semantic Technologies

provide an abstraction layer above existing information technologies in order to bridge and interconnect data, content, and processes. Using semantic technologies, the process of adding, changing and implementing new relationships or interconnecting programs is relatively straightforward. From the portal perspective, semantic technologies can be thought of as a new level of depth that provides an improved, intelligent, relevant, and responsive interaction compared to that available with “classical” information technologies alone.

Technologies that permit to add semantic metadata to information resources. Semantic metadata allow to effectively process data, for instance via automated inferences, that is, understanding what a data resource is and how it relates to other data independently of its name and syntax.
