Clinical temporal expression normaliser.
##How to use it
The normaliser can be used in two different settings.
We provide a temporal expression and an utterance time point. The normalisation is carried out with respect to such date. The utterance time point plays a crucial role in the normalisation of deictic temporal expressions ('today', 'a month ago', 'in two months').
$ python clinical_norma.py 'approximately on June' 20130212 ('approximately on june', 'DATE', '2013-06', 'Month', 'APPROX') $ python clinical_norma.py 'approximately on June' 20150212 ('approximately on june', 'DATE', '2015-06', 'Month', 'APPROX')
You may alternatively want to provide a clinical document and a temporal expression (format YYYYMMDD). In this case, the document is analysed and the pivotal clinical dates are extracted (date of admission, discharge, operation, transfer) to then be used by the normaliser as utterance time points.
$ python normaliser.py [file_to_analyse] 'postoperative day #4' ('postoperative day #4', 'DATE', '2012-01-20', 'postoperative_num1', 'NA') $
The output is a set of 5 elements: 1) temporal expression post-processed 2) type 3) value 4) name of the fired rule 5) modifier.
