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.
In the present study, a source identification problem for a one-dimensional hyperboic equation is studied. Using tools operator approach we are enabled to establish stability estimates for the solution of the source identification problem. Furthermore, a first order accuracy difference scheme for the numerical solution of the source identification problem is presented. Then, this difference scheme is tested on an example and some numerical results are presented.
