The measure was originally proposed by Claude Shannon in 1948 to quantify the entropy (hence Shannon entropy, related to Shannon information content) in strings of text. The idea is that the more letters there are, and the closer their proportional abundances in the string of inter…

"WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i p i log b p i, where p i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). " - Shannon weaver index
