Learning Numeral Embeddings

Jiang, Chengyue, Nian, Zhonglin, Guo, Kaihao et al.

Understand

Word embedding is an essential building block for deep learning methods for natural language processing.

  • Although word embedding has been extensively studied over the years, the problem of how to effectively embed numerals, a special subset of words, is still underexplored.
  • Existing word embedding methods do not learn numeral embeddings well because there are an infinite number of numerals and their individual appearances in training corpora are highly scarce.
  • In this paper, we propose two novel numeral embedding methods that can handle the out-of-vocabulary (OOV) problem for numerals.
