PyRuSH

PyRuSH is the python implementation of RuSH (Ru le-based sentence S egmenter using H ashing), which is originally 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.

How to use

A standalone RuSH class is available to be directly used in your code. From 1.0.4, pyRush adopt spaCy 3.x api to initiate an component.

>>> from PyRuSH import RuSH >>> input_str = "The patient was admitted on 03/26/08n and was started on IV antibiotics elevation" +>>> ", was also counseled to minimizing the cigarette smoking.

" >>> rush = RuSH('../conf/rush_rules.tsv') >>> sentences=rush.segToSentenceSpans(input_str) >>> for sentence in sentences: >>> print("Sentence({0}-{1}):t>{2}<".format(sentence.begin, sentence.end, input_str[sentence.begin:sentence.end]))

Spacy Componentized PyRuSH

Start from version 1.0.3, PyRuSH adds Spacy compatible Sentencizer component: PyRuSHSentencizer.

>>> from PyRuSH import PyRuSHSentencizer >>> from spacy.lang.en import English >>> nlp = English() >>> nlp.add_pipe("medspacy_pyrush") >>> doc = nlp("This is a sentence. This is another sentence.") >>> print('n'.join([str(s) for s in doc.sents]))
