[PDF] Top 20 Robustness to Capitalization Errors in Named Entity Recognition

... There are two common strategies to improve ro- bustness to capitalization errors. The first is to completely ignore orthograhpic information by us- ing case-agnostic models (Kubala et al., 1998; Robinson et ... See full document
