what would be the effect of noise pollution on environment

... Discussion The presented analysis of the effects of noise in the test corpus on the evaluation of POS taggers leads us to conclude that when a tagger is eval- uated as better than another using ... they seem to be. Some of the issues that should be further con- sidered are: The effect of noise on unambigu- ous words; the reasonable intervals for overall real performance; the -probably- ... comparisons between them.
