Corpora: Distribution of homography and lemmas

[Nada S. ILIC]

Dear list members,

I would like to ask does anybody know anything about researches on :
1) distribution of homography in English or other languages
2) distribution of new lemmas as a function of sample size (for example: if
the 100 mil. word corpus is increased for 50 mil., what is the approximate
number of new lemmas)

Thanking in advance
