The document discusses semantics and semantic technology. It describes semantics as being about interaction via meaning. It explains that ontologies are used to create context from which new information can be inferred. Examples are given of how semantics can be used, including for e-commerce, search engine optimization, and making use of information from different sources on the internet in a safe manner through linked data.
