I could not find the time to precise my question and then received a lot of very interesting answers and references. Thank you all for this!
In fact, I should have said that I'm looking for the number of ambiguous word tokens in terms of POS in an English corpus, for example from the Penn TreeBank. One solution would be to compute this myself from the Brown corpus, but I was curious if there was a ref. on this.
I found this ref for French that says 60% of the French tokens in their corpus were non ambiguous in terms of POS: Tzoukermann, E.; Radev, D. R. & Gale, W. A. Ken Church, Susan Armstrong, P. I. E. T. & Yarowsky, D. (ed.) Natural Language Processing Using Very Large Corpora Tagging french without lexical probabilities -- combining linguistic knowledge and statistical learning Kluwer Academic, 1999
Of course, it all depends on the number of tags, their refinement et so on. It only gives a very rough idea and should be taken in its context, obviously. But that's all I need.
Best,
Karen
