Hi I am new to ctakes, I have got few questions, Please guide me with your inputs.
1. When a clinical note is inputted to ctakes, it will process that text in multi stages. Let us take an eg of a clinical note :- SINGLE/PRETERM (35 WEEKS 5 DAYS)/MALE/AGA. Here the word "preterm" is not in dictionary, preterm infant, premature baby etc is there. So ctakes is not identifying that word as coveredText. My question is does ctakes processing mainly depends on exact word match with the dictionary. If so If i give one page of clinical note with explanation of disease and if it does not contain exact matching words with dictionary, then ctakes will not identify that word. Is it true? 2. Ctakes does POS tagging and does named entity recognition on the noun terms. How to pull out a list of nouns created which are not matched to a named disorder code at the named entity recognition level. Regards Vighnesh
