Original from https://code.google.com/p/word2vec/

I’ve copied it to a github project so I can apply and track community

patches for my needs (starting with capability for Mac OS X

compilation).

- **makefile and some source has been modified for Mac OS X

compilation** See

https://code.google.com/p/word2vec/issues/detail?id=1#c5

- **memory patch for word2vec has been applied** See

https://code.google.com/p/word2vec/issues/detail?id=2

- Project file layout altered

There seems to be a segfault in the compute-accuracy utility.

To get started:

::

Original README text follows:

This tool provides an efficient implementation of the continuous bag-of-words and skip-gram architectures for computing vector representations of words. These representations can be subsequently used in many natural language processing applications and for further research.

this code provides an implementation of the Continuous Bag-of-Words (CBOW) and

the Skip-gram model (SG), as well as several demo scripts.

Given a text corpus, the word2vec tool learns a vector for every word in

the vocabulary using the Continuous Bag-of-Words or the Skip-Gram neural

network architectures. The user should to specify the following: -

desired vector dimensionality - the size of the context window for

either the Skip-Gram or the Continuous Bag-of-Words model - training

algorithm: hierarchical softmax and / or negative sampling - threshold

for downsampling the frequent words - number of threads to use - the

format of the output word vector file (text or binary)

Usually, the other hyper-parameters such as the learning rate do not

need to be tuned for different training sets.

The script demo-word.sh downloads a small (100MB) text corpus from the

web, and trains a small word vector model. After the training is

finished, the user can interactively explore the similarity of the

words.
