    Abstract

    We describe a cross-corpora evaluation of disease mention recognition for two annotated biomedical corpora: the Human Variome Project Corpus and the Arizona Disease Corpus. Our analysis of the performance of a state-of-the-art NER tool in terms of the characteristics and annotation schema of these corpora shows that these factors significantly affect performance.
