I am trying to use the word2vec
module from gensim
natural language processing library in Python.
The docs say to initialize the model:
from gensim.models import word2vec
model = Word2Vec(sentences, size=100, window=5, min_count=5, workers=4)
What format does gensim
expect for the input sentences? I have raw text
"the quick brown fox jumps over the lazy dogs"
"Then a cop quizzed Mick Jagger's ex-wives briefly."
etc.
What additional processing do I need to post into word2fec
?
UPDATE: Here is what I have tried. When it loads the sentences, I get nothing.
>>> sentences = ['the quick brown fox jumps over the lazy dogs',
"Then a cop quizzed Mick Jagger's ex-wives briefly."]
>>> x = word2vec.Word2Vec()
>>> x.build_vocab([s.encode('utf-8').split( ) for s in sentences])
>>> x.vocab
{}
A list of utf-8
sentences. You can also stream the data from the disk.
Make sure it's utf-8
, and split it:
sentences = [ "the quick brown fox jumps over the lazy dogs",
"Then a cop quizzed Mick Jagger's ex-wives briefly." ]
word2vec.Word2Vec([s.encode('utf-8').split() for s in sentences], size=100, window=5, min_count=5, workers=4)
