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

Addressing to the problems of analysis and information securityrisks assessment there is a common need to performthe data processing in fuzzy environments. To implementthis process, the system where an assessment is based onlinguistic variables, based on the standard parametric trapezoidalfuzzy numbers with a specified number of terms isused. The formation of standards is a complex procedurethat is implemented with the experts assistance in correspondingsubject area. In the practical use of mentionedsystem, there is a need for a rapid change of terms, for example,to bring them to a single point. There is a lack ofdescribed capabilities to vary in existing systems. To addresssuch challenge and enhance the effectiveness of riskassessment the n-fold decrease method of terms numbersof linguistic variables is proposed. This method allows tooverride the number of terms of linguistic variables withoutexperts assistance.
