Yes, that's essentially the idea behind a collocation
- that the two items next to each other mean more than
they do apart. "Tennis Court" means a very specific
idea, seperate from the words "tennis" and "court" on
Using a likelihood ratio to find collocations can be
done on either letter-letter or word-word combinations
(where you would take the spaces to indicate the word
boundary). Problem is... just about everything in
language is "on purpose" and statistically signficant.
So "and the" is signficant, along with "tennis court"
and just about everything else that appears in
However, I haven't tried colocation likelihood
measurements on gibberish or heavily encrypted text
(by that i mean, a simple substitution cipher would
behave the same as plain text for collocations). I
would guess in these cases the number of significant
collocations would drop, but by how signficantly I
don't know. I did run collocation likelihoods once on
the VMS text (see my long message about concentrating
on known languages) and didn't see any anomolies (the
character combinations we always see together - 4o -
