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

The principle of an invariableness of designations of the basic quantities (30-40 quantities) is the basis for uniform system of letter designations of quantities which should not have synonymous (reserve) designations and must to be used strictly in all disciplines. The table of designations of such main quantities are given. At the same time symbols of the basic quantities are polysemantic and can be used for designation of quantities which were not included into the table of the main quantities. The polysemantic term "amount of substance" is offered to replace by unambiguous term "molarity of substance" or in abbreviated form "molarity" and to input a uniform symbol for this quantity.
