HUGO Gene Nomenclature Committee, a committee assigning unique names to genes.
Become familiar with the HUGO site, then read: The success (or not) of HUGO nomenclature (Genome Biology, 2006).
Now read: Moara: a Java library for extracting and normalizing gene and protein mentions (BMC Bioinformatics 2010)
Q: How you would apply the techniques in the Moara article to build a topic map? Would you keep/discard normalization?
