# Selector
**Entity class:** Identity-Resolution Layer concept
**Selector** is a concept in the identity-resolution of the counterterrorism predictive-graph ontology. Selector matters because the analytic object is a changing, partially observed system rather than a finished dossier.
## Counterterrorism predictive-graph role
A relationship or identity match is an evidence-bearing hypothesis with source, time, and confidence. It is not guilt by association. The analytic state should distinguish ground truth, observed evidence, inferred state, and predicted state.
