ICML 2015: New SOA for Neural Word Embeddings by Modeling Word and Char Order (arxiv.org)

In plain words: A word-embedding model that tracks both the order of words and the order of letters inside them, so vectors capture grammar and word parts instead of just which words appear together. It scored 85.8% on a word-analogy test, beating the best published scores for grammar-related analogies.

Abstract · Modeling Order in Neural Word Embeddings at Scale

Natural Language Processing (NLP) systems commonly leverage bag-of-words co-occurrence techniques to capture semantic and syntactic word relationships. The resulting word-level distributed representations often ignore morphological information, though character-level embeddings have proven valuable to NLP tasks. We propose a new neural language model incorporating both word order and character order in its embedding. The model produces several vector spaces with meaningful substructure, as evidenced by its performance of 85.8% on a recent word-analogy task, exceeding best published syntactic word-analogy scores by a 58% error margin. Furthermore, the model includes several parallel training methods, most notably allowing a skip-gram network with 160 billion parameters to be trained overnight on 3 multi-core CPUs, 14x larger than the previous largest neural network.
