LINNAEUS: Run with LINNAEUS’s default species matcher and post-processor, which recognizes species terms from the 10 000 most frequently occurring species in MEDLINE.
LINNAEUS+: Run with entity type dictionary packs downloaded from http://linnaeus.sourceforge.net/. The packs contain updated dictionary files and support normalization of genus names and post-processing instructions.
