- I don't know about 30:1 for text information, but I can suggest a couple
- of clues as to where they might be coming from; see:
-
- "Source encoding using syntactic information source models",
- R.D.Cameron, IEEE Txns on Info Theory Vol 34 No 4 July 1988
- Compression of pascal programs (what simpler grammar could you want?)
- The approach was to attack a compressible object as a structure
- from the top down, rather than as a stream of bytes with a
- uniform Markovian model.
-
- "Shortening the OED: Experience with a grammar-defined database"
- Blake, Bray and Tompa (U. of Waterloo), ACM Txns on Info Systems, Vol 10
- No 3 July 1992.
- A practical attack on natural language objects with a limited
- (for natual language) grammar. Awesome real results.
