Published: — with international search report (Art. 21(3)) 1-1 (54) Title: WORD VECTOR PROCESSING METHOD AND APPARATUS ot (57) : Embodiments of the present application disclose a word vector processing method and apparatus. The method includes: performing word segmentation on a corpus to obtain words; determining n-gram strokes corresponding to the words, the n-gram stroke representing n successive strokes of a corresponding word; establishing and initializing word vectors of the words and stroke vectors 1-1 of the n-gram strokes corresponding to the words; and training the word vectors and the stroke vectors according to the corpus obtained after the word segmentation, the word vectors, and the stroke vectors. With the embodiments of the present application, features of a 1-1 © word can be shown more precisely by using n-gram strokes corresponding to the word, thus enhancing accuracy of word vectors of N Chinese words and achieving a desirable practical effect.
