Hello All-
best wishes for a good 2014. I have a question about using a radiology-related ontology, RadLex, in cTakes. If somebody out there has imported and used in processing radiology reports we'd like to hear from them to share their experience. A couple of specific questions: 1. what are the pros and cons of implementing RadLex as a custom dictionary, or as a part of UMLS-sanctioned ontology even though it is not yet part of UMLS but it is part of NCI's Metathesaurus 2. what would be a the preferred way to import it in cTakes - via an RRF upload, or other custom format 3. could one take a NCImThesaurus download from NCI and use it to import RadLex 4. in a recent discussion regarding difference between custom dictionaries and UMLS imported ontologies "How to augment/modify UMLS resources?" it looks like cTakes would actually process the note once for the UMLS supplied resources and once for the (each?) custom dictionary, if i understand this correctly. Wouldn't it then be very inefficient to have multiple custom dictionaries, as opposed to try to maximize the UMLS ones? Any difference in the YTex behavior (VJ, please chime in) More generally, what are the pros and cons of using all of i.e. the UMLS Metathesaurus (or the NCImThesaurus) as ontology dictionaries in cTakes, apart from licensing issues? Thanks, vlad Brigham rad
