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 substitution in polymer1‐fluorescence dye‐competitor systems was investigated by measurement of the dye fluorescence. It is ascertained that the main factor affecting the direction of the possible reaction is the nature of the competitor. According to their ability to substitute dyes, different competitors can be arranged in the following series: polyelectrolytes > nonionic polymers ≥ surfactants > metal ions.
