Working on NWRM requires understanding of a broad range of key concepts. This page gathers definitions for a set of key concepts used when addressing NWRM. It sets a shared ontology, with interlinkages between concepts. Semantic annotations have been developed and the associated ontology represented thanks to a relation graph.

Semantic Annotation helps to bridge the ambiguity of the natural language when expressing notions and their computational representation in a formal language. By telling a computer how data items are related and how these relations can be evaluated automatically, it becomes possible to process complex filter and search operations. (source:
