Intrinsic evaluation of the text mining system for extracting residue mentions and/or mutation mentions.

Three corpora were evaluated. E₁ contains only annotations of mutations, and is subdivided into development (E_{1_dev}) and test (E_{1_test}) corpora. E₂ and E₃ include annotations of residues and mutations. E₂ consists of abstracts only, while E₃ consists of full text articles.
