2016-6-24 · Pre-trained word vectors of 30+ languages. This project has two purposes. First of all, I'd like to share some of my experience in nlp tasks such as segmentation or word vectors. The other, which is more important, is that probably some people are searching for pre-trained word vector models for non-English languages. Alas!
2017-6-7 · Vector-space models of semantics represent words as continuously-valued vectors and measure similarity based on the distance or angle between those vectors. Such representa-tions have become increasingly popular due to the recent de-velopment of methods that allow them to be efficiently esti-mated from very large amounts of data. However, the idea
