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.
We study semantic and syntactic properties of spherical orders and their elementary theories, including nite and dense orders and their theories.It is shown that theories of dense n-spherical orders are countably categorical and decidable.The values for spectra of countable models of unary expansions of n-spherical theories are described.The Vaught conjecture is conrmed for countable constant expansions of dense n-spherical theories.
