Relationship type
A relationship type is a label or category identifying the kind of connection represented by an edge in a graph.
Graph Neural Networks in Action
An edge type is a category identifying the kind of relationship represented by a graph edge.
- How it is used
- Distinguishes known molecular bond categories or represents inferred connections used to predict future graph states and trajectories.
- How deep it goes
- Works through relation-specific message-passing parameters and a probability-to-sampled-edge inference pipeline, without deriving their mathematics.
- Examples
- Uses single, double, triple, and aromatic molecular bonds alongside connected-versus-unconnected sensors and possible sports-team passing links.
- What you can do after
- Build it from scratch with relation-specific message passing, or apply edge-type sampling to infer connectivity for trajectory prediction.

Graph Algorithms for Data Science
A relationship type is a label that identifies the kind of connection represented by a graph relationship.
- How it is used
- Uses relationship types to model and query meaningful connections in social, business, geographic, and other graph domains.
- How deep it goes
- Explains relationship semantics, direction, properties, naming quality, and graph triples without descending into database implementation internals.
- Examples
- Demonstrates FRIEND, WRITES_FOR, EMPLOYED_BY, IS_IN, HAS_TAG, and SIMILAR relationships through graph models, Cypher listings, and network projections.
- What you can do after
- Apply relationship types via Cypher to create, retrieve, traverse, and interpret typed graph connections.
