Requirements

Git
MeCab

MeCab Checker: src/check_mecab.py



How to use

Make *.model file

# Install from pypi
pip install aovec

# Clone aozorabunko/aozorabunko (>20GB)
aovec clone

# Parse html files and write to results to novels/
aovec parse

# Make word2vec and write to aozora_model.model
aovec mkvec


Use from Python (See: official document)

from gensim.models import Word2Vec, KeyedVectors

# *.model+*.model.syn1neg.npy+*.model.wv.vectors.npy
model = Word2Vec.load('aozora_model.model')

# or...
# *.kv
model = KeyedVectors.load_word2vec_format('aozora_model.kv')

# or...(fastest way to load)
# *.kv.bin
model = KeyedVectors.load_word2vec_format('aozora_model.kv.bin',
binary=True,
unicode_errors='ignore')
