 Quantifying Information Content Does Not Bring Meaning Fr...

However, Shannon’s method provides only a quantitative measure of the complexity of a language or signaling system—not a translation. And while it is axiomatic in cryptology that redundancy helps in deciphering a text, the task of decipherment/cryptanalysis is to move from an encoded text to the original text—not from text to meaning.
