Python impl for TextRank
Python implementation of TextRank, based on the
Mihalcea 2004 <http://web.eecs.umich.edu/~mihalcea/papers/mihalcea.emnlp04.pdf>_
paper.
Modifications to the original algorithm by
Rada Mihalcea <https://web.eecs.umich.edu/~mihalcea/>_, et al.
include:
- fixed bug; see
Java impl, 2008 <https://github.com/ceteri/textrank>_ - 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 <http://mike.place/2016/summarization/>_
talk on text summarization.
Example Usage
See PyTextRank wiki <https://github.com/ceteri/pytextrank/wiki/Examples>_
Dependencies and Installation
This code has dependencies on several other Python projects:
spaCy <https://spacy.io/docs/usage/>_NetworkX <http://networkx.readthedocs.io/>_datasketch <https://github.com/ekzhu/datasketch>_graphviz <https://pypi.python.org/pypi/graphviz>_
To install from PyPi <https://pypi.python.org/pypi/pytextrank>_:
::
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
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.
