I'd like to understand the distinction between source and target vocabularies when building a custom dictionary in cTAKES. Are source vocabularies used for tagging, and target vocabularies computed via mapping after, similarly to the ontology mapping files provided by UMLS? If this is the case, what is the purpose of selecting target vocabularies, if all could be selected as source?
I'd like to be able to tag concepts with SNOMED, RxNORM, and ICD9/ICD10. I observed that the default resources do not include ICD codes; I tried as well to use the provided resources from this thread <http://mail-archives.apache.org/mod_mbox/ctakes-dev/201512.mbox/%[email protected]%3E>, but couldn't connect to the database in this case. Thank you! Sarah
