A generic, machine learning-based revision scoring system designed to be used to automatically differentiate damage from productive contributory behavior on Wikipedia.
Using a scorer_model to score a revision::
import mwapi
from revscoring import Model
from revscoring.extractors.api.extractor import Extractor
with open("models/enwiki.damaging.linear_svc.model") as f:
scorer_model = Model.load(f)
extractor = Extractor(mwapi.Session(host="https://en.wikipedia.org",
user_agent="revscoring demo"))
feature_values = list(extractor.extract(123456789, scorer_model.features))
print(scorer_model.score(feature_values))
{'prediction': True, 'probability': {False: 0.4694409344514984, True: 0.5305590655485017}}
The easiest way to install is via the Python package installer (pip).
pip install revscoring
You may find that some of the dependencies fail to compile (namely
scipy
, numpy
and sklearn
). In that case, you'll need to install some
dependencies in your operating system.
- Run
sudo apt-get install python3-dev g++ gfortran liblapack-dev libopenblas-dev
- Run
apt-get install aspell-ar aspell-bn myspell-cs myspell-nl myspell-en-us myspell-en-gb myspell-en-au myspell-et voikko-fi myspell-fr myspell-de-at myspell-de-ch myspell-de-de myspell-he myspell-hu aspell-id myspell-it myspell-nb myspell-fa aspell-pl myspell-pt myspell-es aspell-sv aspell-ta myspell-ru myspell-uk hunspell-vi
TODO
Using Homebrew and pip, installing revscoring
and enchant
can be accomplished
as follows::
- brew install aspell --with-all-languages
- brew install enchant
- pip install --no-binary pyenchant revscoring
cd /tmp
wget http://ftp.gnu.org/gnu/aspell/dict/pt/aspell-pt-0.50-2.tar.bz2
bzip2 -dc aspell-pt-0.50-2.tar.bz2 | tar xvf -
cd aspell-pt-0.50-2
./configure
make
sudo make install
Caveats:
The differences between the aspell
and myspell
dictionaries can cause
some of the tests to fail
Finally, in order to make use of language features, you'll need to download some NLTK data. The following command will get the necessary corpus.
python -m nltk.downloader stopwords
You'll also need to install enchant <https://en.wikipedia.org/wiki/Enchant_(software)>
