Shannon index interpretation

The Shannon index has been a popular diversity index in the ecological literature, where it is also known as Shannon's diversity index, Shannon–Wiener index, and (erroneously) Shannon–Weaver index. 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… WebbWe consider that the visual semiotics of the Quebec School represented by Saint-Martin and Shannon´s entropic comparison of the Venus table paintings may be applied to both classical and contemporary pictorial works to support the work of art historians.
