Hi Ghandi, "plan" is a synonym for C0270724: Infantile Neuroaxonal Dystrophy.
One outcome of using generic dictionaries that can be used across multiple fields of interest is that a valid term in one field can be misapplied to text from another. Unwanted terms can be addressed per item by creating a more pointed dictionary without them, adding them to a blacklist that causes ctakes to discard them, or removing them with some kind of discriminating annotator. The last includes application of word sense disambiguation, a hot topic on this forum as well as others. If you create a custom dictionary you can add medDRA terms. https://cwiki.apache.org/confluence/display/CTAKES/Dictionary+Creator+GUI Sean -----Original Message----- From: Gandhi Rajan Natarajan [mailto:gandhi.natara...@arisglobal.com] Sent: Saturday, September 09, 2017 2:22 PM To: dev@ctakes.apache.org Subject: Filtering disease term precisely from EventMention and loading MedDRA library for cTAKES [EXTERNAL] HI All, we have deployed temporal demo application available under https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_healthnlp_examples_tree_master_ctakes-2Dtemporal-2Ddemo&d=DwIFAg&c=qS4goWBT7poplM69zy_3xhKwEW14JZMSdioCoppxeFU&r=fs67GvlGZstTpyIisCYNYmQCP6r0bcpKGd4f7d4gTao&m=Gl0bP7oHY9HLCgAy9GMSpAb9x-phGTB1-nYh2G7SrWY&s=bKUnUuurg3wWfzmjUKWhFIHzaVGylX_kIaj6f83c4m4&e= locally and referring to dictionaries(RxNORM,SnoMED) loaded in MySQL DB. We are trying to extract out disease terms using this application. When we tried out the text mentioned in user installation guide, " Dr. Nutritious Medical Nutrition Therapy for Hyperlipidemia Referral from: Julie Tester, RD, LD, CNSD Phone contact: (555) 555-1212 Height: 144 cm Current Weight: 45 kg Date of current weight: 02-29-2001 Admit Weight: 53 kg BMI: 18 kg/m2 Diet: General Daily Calorie needs (kcals): 1500 calories, assessed as HB + 20% for activity. Daily Protein needs: 40 grams, assessed as 1.0 g/kg. Pt has been on a 3-day calorie count and has had an average intake of 1100 calories. She was instructed to drink 2-3 cans of liquid supplement to help promote weight gain. She agrees with the plan and has my number for further assessment. May want a Resting Metabolic Rate as well. She takes an aspirin a day for knee pain", it extracted out 'Hyperlipidemia' and 'plan' as DiseaseDisorderMention. But we expected only disease terms to be extracted out(Hyperlipidemia) but "plan" is not what we expected. How do we avoid this or filter out only disease terms like fever, red eye, nausea etc. from the given text. Any help on this is greatly appreciated. Also please let us know is there a provision to load MedDRA dictionaries and lookup the same in cTAKES? If yes, please let us know how to achieve it?
