# Cross-Lingual Eigenwords

**Cross-Lingual Eigenwords** is a cross-lingual word embedding method, based on spectral graph embedding.

The above figure is 2-dim visualization (by PCA) of **CL-Eigenwords** word vectors of names of countries and its languages in English (blue) and Spanish (red). Words of each (country, language) pair (ex. (italy, italian) ) are connected by a line segment.
