30k diachronic Chinese-language SGNS word embeddings, 5 decades, Google Books corpus

30 thousand SGNS embeddings from the HistWords project, trained on the Google Books N-Gram corpus (all Chinese) divided into decades. This is a list of 5 elements, in which every element is an embedding matrix associated with a given decade, 1950-1990. Each matrix is30 thousand vectors (rows) and 300 dimensions (columns). Note that each embedding has the same vocabulary, but when words do not appear in a given decade they appear as rows with only zero values.

if (FALSE) {


## download the model (once per machine)
