Data confidence 70 medium
How this score is calculated

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.

Abstract

Here we study non-trivial expansions of 1-transitive ordered theories preserving 1-transitivity. In particular, expansions of weakly o-minimal linear orderings by equivalence relations, unary functions and arbitrary binary relations were investigated. On the base of the obtained results values of ranks for various families of weakly o-minimal theories were found.
