Semantics is a branch of linguistics concerned with studying the meanings of words and sentences. The main purpose is to facilitate information sharing, to create common ontologies and to enhance the reasonability of context use. Today, semantics is widely used in knowledge representation and information sharing. Drugs being complex chemical structures require simple nomenclature for day to day use. Drug nomenclature has evolved gradually. Historically, fascination, curiosity and serendipity or just gut-feelings have been involved in naming drugs. A systematic approach has only, recently been adopted.
