Python impl for TextRank
Python implementation of TextRank, based on the Mihalcea 2004 paper.
Modifications to the original algorithm by Rada Mihalcea, et al. include:
fixed bug; see Java impl, 2008
use of lemmatization instead of stemming
verbs included in the graph (but not in the resulting keyphrases)
named entity recognition
normalized keyphrase ranks used in summarization
The results produced by this implementation are intended more for use as feature vectors in machine learning, not as academic paper summaries.
Inspired by Williams 2016 talk on text summarization.
Example Usage
See PyTextRank wiki
Dependencies and Installation
This code has dependencies on several other Python projects:
To install from PyPi:
pip install pytextrank
To install from this Git repo:
pip install -r requirements.txt
After installation you need to download a language model:
python -m spacy download en_core_web_sm
Also, the runtime depends on a local file called stop.txt which contains a list of stopwords. You can override this in the normalize_key_phrases() call.
