Impact of scientific production, Webometric indicators, Web Impact Factor Formula FIW, Natural logarithmAbstract
Displays a history of measuring the impact of scientific articles and shows the need to extend this assessment to the web. Describes how the impact factor on websites has been calculated and proposes a change in the original formula, with the inclusion of a natural logarithm in its denominator in order to obtain more accurate results. The new formula is applied to websites of federal universities in Southeastern Brazil.
