The effects of missing synonymy on disease name normalization.

This table indicates the total fraction of recall attributable to synonymy (third column) for four different normalization algorithms (first column) and two different gold-standard corpora (second column). The fourth column indicates the fraction of concepts in the third column whose recall depended on redundant synonyms, and the fifth column provides the fraction of the total number of synonyms predicted to be redundant for the recalled concepts (mean plus 95% confidence interval).The effects of missing synonymy on disease name normalization.
