Hi Sangram, I would love to say that I have a simple answer for you, but I don't. There is an engine that will attempt to identify events as hedged, hypothetical, actual or generic ... the ContextualModalityAnnotator in the ctakes-temporal module. However, it is not in the commonly used pipelines, and I have no idea how well it works. It is possible that somebody else out there is using this annotator to great success or at least knows more about it than I.

I have patient-clinical-notes e.g. - 83 y.o. Asian gentleman who is status post a robotic-assisted radical prostatectomy in October of 2006 for pathologic stage T2c, Gleason 4+3 prostate cancer excised with a negative surgical margin but benign glands at the margin. - The patient is a 73-year-old Caucasian gentleman who is status post radical prostatectomy in 2006. - Greater than 30 minutes of face to face discussion time were spent discussing the prostate gland, prostate diseases and prostate cancer. We discussed open radical prostatectomy, daVinci prostatectomy, external beam radiation, brachytherapy, cryotherapy, androgen deprivation, watchful waiting and HIFU. - We discussed different treatment options for prostate cancer. We discussed non-curative options including active surveillance and hormone therapy. We also discussed potentially curative options including surgery versus radiation and cryotherapy. The note gets annotated using clinical pipeline - AggregatePlaintextFastUMLSProcessor. By searching keyword I can find a treatment. sometimes physician writes about the discussion and sometime the actual surgery. Now I have problem to finalise if the mentioned procedure/treatment is really happened or just discussed. I can't just rely on verb in the sentence. Your help would help me a lot!
