# Link Prediction **Entity class:** Graph-analytic task **Maturity:** Developed ## Definition **Link prediction** estimates the likelihood that an unobserved or future edge exists between graph entities. In counterterrorism it can prioritize possible hidden relationships, but it produces hypotheses rather than proof. Missing data, homophily, shared infrastructure, and adversarial manipulation can create consequential false positives. ## Relationships - **part of:** [[wiki/Graph Analytics|Graph Analytics]]. - **uses:** [[wiki/Graph Neural Network|Graph Neural Network]], topology, and node or edge attributes. - **depends on:** [[wiki/Entity Resolution|Entity Resolution]]. - **applied to:** [[wiki/Dark Network|Dark Network]] and [[wiki/Counterterrorism Intelligence|Counterterrorism Intelligence]]. ## Sources / Provenance - [[research/A Network-Epidemiological Analysis of Radicalization and Real-Time Counterterrorism Observability|Network-Epidemiological Analysis]]
