Like you said, the distinction between meaning and information is largely superficial and arbitrary. Letters are symbols, symbols carry meaning - a particular squiggle only contains information because it has meaning (outside of models and other artificial systems). If I don't read Sanskrit, one letter contains zero information/meaning for me.
"If something is more probable, it contains less information." I don't understand, why would "ee" contain less information than "hh"?
I'm also wondering where his comparison of English to Japanese came from:
"For instance, we could compare the number of bits per character in Japanese versus English (it turns out that English is only 60% as compact as Japanese, which explains why Japanese book are always around two-thirds the size of their English counterparts...)."
Are we talking about kanji or hirigana/katakana? If we're talking about kanji, we're talking about thousands of pictographic symbols (a lot of which are multi-syllabic), which are fundamentally different in nature than English letters (as for the 60% more compact bit, citation please?).
Based on his own assertion, "Let’s say that there are 32 letters and punctuation marks... each character represents 5 bits of information ... a total of 5*16 = 80 bits of information." There's somewhere between 2000-7000 kanji ... so each character would represent...?
- rosser 17y agoI don't understand, why would "ee" contain less information than "hh"? He's not talking about "information" in the sense of "facts" in this case. Do some reading on Shannon entropy for the details, but broadly, take the following example. $ grep -c ee /usr/share/dict/words 10620 $ ^ee^hh grep -c hh /usr/share/dict/words 132 Suppose you're looking for a given word out of some arbitrarily defined set of words, such as a dictionary file. Suppose further you're given either the clue that it contains the sequence "ee", or the sequence "hh". There's a much lower probability of any specific one of the 10000-odd words in the set being the match for "ee" than one of the 100-odd for "hh". In information-theoretic terms, that probability gives you useful data, or information, about the word you're looking for.
