4. Evaluation system: proposal of an integrated framework Scores resulting from the comparison process must be interpreted as a link value through a formalised evaluation system.
Approaches based on a deterministic or a Bayesian framework are common solutions across forensic literature and practice [25].
They are often regarded as antagonistic and mutually exclusive. In opposition to that view, an evaluation framework combining both approaches is advocated here to meet the flexibility criteria mentioned in Section 2.
The commonality between these evalua-tion approaches is their ability to assess credibility and integrity criteria through the expression of type I, and type II error rates. Both approaches have been presented and practically applied in [15].
Therefore, they will only be briefly described in the present article.
