aovec

• Make Word2Vec from aozorabunko/aozorabunko

• Pre-built models are available from week* Releases.

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 built model from Python (See: official document)

• *.model

from gensim.models import Word2Vec

model = Word2Vec.load('aozora_model.model')

• *.kv

from gensim.models import KeyedVectors

model = KeyedVectors.load_word2vec_format('aozora_model.kv')

• *.kv.bin (fastest)

from gensim.models import KeyedVectors

model = KeyedVectors.load_word2vec_format('aozora_model.kv.bin',
                                          binary=True,
                                          unicode_errors='ignore')
