It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Our previous paper [4] has an error in the proof of Theorem 1.3. In the paper, we give a counterexample for Theorem 1.3 in [4]. We present the correct formulation of Theorem 1.2, in which we prove the equality \(\text{cat}(\phi)=\text{cd}(\phi)\) for homomorphisms \(\phi:\Gamma\to \Lambda\) between finitely generated abelian groups \(\Gamma\) and \(\Lambda\), where \(\phi(T(\Gamma))=0\) for the torsion subgroups \(T(\Gamma)\) of \(\Gamma\).
