A fast implementation of RuSH (Rule-based sentence Segmenter using Hashing).

Project description


PyRuSH is the python implementation of RuSH, which is orginally developed using Java. RuSH is an efficient, reliable, and easy adaptable rule-based sentence segmentation solution. It is specifically designed to handle the telegraphic written text in clinical note. It leverages a nested hash table to execute simultaneous rule processing, which reduces the impact of the rule-base growth on execution time and eliminates the effect of rule order on accuracy.

pip install PyRuSH

How to use:

A standalone RuSH class is available to be directly used in your code.

from PyRuSH.RuSH import RuSH
input_str = "The patient was admitted on 03/26/08\n and was started on IV antibiotics elevation" +\
", was also counseled to minimizing the cigarette smoking. The patient had edema\n\n" +\
"\n of his bilateral lower extremities. The hospital consult was also obtained to " +\
"address edema issue question was related to his liver hepatitis C. Hospital consult" +\
" was obtained. This included an ultrasound of his abdomen, which showed just mild " +\
"cirrhosis. "
rush = RuSH('../conf/rush_rules.tsv')
for sentence in sentences:
print('Sentence({0}-{1}):\t>{2}<'.format(sentence.begin, sentence.end, input_str[sentence.begin:sentence.end]))
