ESpotter
ESpotter is a browser plug-in which improves NER on the Web by adapting lexicons and patterns to domains on the Web and user preferences.
LingPipe

NLProt
"NLProt is a tool for finding protein-names in natural-language text. It is based on Support Vector Machines, which are trained on contextual-features of named entities in scientific language."
POSBioTm/NER
A web-based and trainable biomedical named entity recognition system. Modules are provided online which have been trained on a variety of corpera.
Yapex
A protein name tagger developed in the project "Proteinhalt i text" (Protein Concentration in Text). The tagger uses information from lexical analysis, syntactic analysis and some knowledge bases. The syntactic analysis is based on the output from the English Functional Dependency Grammar parser from Conexor Oy
YooName
A generic Named Entity Recognition software based on semi-supervised learning. It identifies nine named entity categories that are split into 100 sub-categories.
