See the [project page](http://nlp.stanford.edu/projects/glove/) or the [paper](http://nlp.stanford.edu/pubs/glove.pdf) for more information on glove vectors. ## Download pre-trained word vectors The links below contain word vectors obtained from the respective corpora. If you want word vectors trained on massive web datasets, you need only download one of these text files! Pre-trained word vectors are made available under the <a href="http://opendatacommons.org/licenses/pddl/">Public Domain Dedication and License</a>. <div class="entry"> <ul style="padding-left:0px; margin-top:0px; margin-bottom:0px"> <li> Common Crawl (42B tokens, 1.9M vocab, uncased, 300d vectors, 1.75 GB download): <a href="http://nlp.stanford.edu/data/wordvecs/glove.42B.300d.zip">glove.42B.300d.zip</a> </li> <li> Common Crawl (840B tokens, 2.2M vocab, cased, 300d vectors, 2.03 GB download): <a href="http://nlp.stanford.edu/data/wordvecs/glove.840B.300d.zip">glove.840B.300d.zip</a> </li> <li> Wikipedia 2014 + Gigaword 5 (6B tokens, 400K vocab, uncased, 300d vectors, 822 MB download): <a href="http://nlp.stanford.edu/data/wordvecs/glove.6B.zip">glove.6B.zip</a> </li> <li> Twitter (2B tweets, 27B tokens, 1.2M vocab, uncased, 200d vectors, 1.42 GB download): <a href="http://nlp.stanford.edu/data/wordvecs/glove.twitter.27B.zip">glove.twitter.27B.zip</a> </ul> </div> ## Train word vectors on a new corpus <img src="https://travis-ci.org/stanfordnlp/GloVe.svg?branch=master"></img> If the web datasets above don't match the semantics of your end use case, you can train word vectors on your own corpus. $ git clone http://github.com/stanfordnlp/glove $ cd glove && make $ ./demo.sh The demo.sh script downloads a small corpus, consisting of the first 100M characters of Wikipedia. It collects unigram counts, constructs and shuffles cooccurrence data, and trains a simple version of the GloVe model. It also runs a word analogy evaluation script in python to verify word vector quality. More details about training on your own corpus can be found by reading [demo.sh](https://github.com/stanfordnlp/GloVe/blob/master/demo.sh) or the [src/README.md](https://github.com/stanfordnlp/GloVe/tree/master/src) ### License All work contained in this package is licensed under the Apache License, Version 2.0.
