On Log-Likelihood-Ratios and the Significance of Rare Events.
Robert C. Moore · 2004
We address the issue of judging the significance of rare events as it typically arises in statistical natural-language processing. We first define a general ap-proach to the problem, and we empirically com-pare results obtained using log-likelihood-ratios and Fisher’s exact test, applied to measuring strength of bilingual word associations. 1
