- Node
- A node is the most elementary unit in the graph. It is the result of the tokenization process, and corresponds to the notion of "lexical item". At the surface level, a natural language sentence is considered a list of nodes, and a UNL graph a set of relations between nodes.
- Relation
- In order to form a natural language sentence or a UNL graph, nodes are inter-related by relations. In the UNL framework, there are three different types of relations: the linear (list) relation, syntactic relations and semantic relations.
- Hyper-Node
- A hyper-node is a sub-graph, i.e., a scope: a node containing relations between nodes.
- Hyper-Relation
- A hyper-relation is a relation between relations.
