NER using MetaMAP

Go to the online MetaMap service (batch mode):

MetaMap will not run on text that contains non-ascii characters, so remove them before using MetaMap. Non-ascii characters can be identified with the regular expression “[^\x00-\x7F]”.

In Output/Display Options, check “Show CUIs (-I)”.

In I would like to only use specific Semantic Types, check the checkbox, and select the semantic types relevant to the phenotype. For example, use

acab, aapp, anab, antb, biof, bacs, bodm, chem, chvf, chvs, clnd, cgab, diap, dsyn, elii, enzy, fndg, hops, horm, imft, irda, inbe, inpo, inch, lbpr, lbtr, medd, mobd, neop, nnon, orch, patf, phsu, phpr, rcpt, sosy, topp, vita

to select the following:
