On the Convergent Properties of Word Embedding Methods [PDF]
arXiv, 2016 Do word embeddings converge to learn similar things over different initializations? How repeatable are experiments with word embeddings? Are all word embedding techniques equally reliable? In this paper we propose evaluating methods for learning word representations by their consistency across initializations.

Think Globally, Embed Locally --- Locally Linear Meta-embedding of Words [PDF]
arXiv, 2017 Distributed word embeddings have shown superior performances in numerous Natural Language Processing (NLP) tasks. However, their performances vary significantly across different tasks, implying that the word embeddings learnt by those methods capture complementary aspects of lexical semantics.

Multiplex Word Embeddings for Selectional Preference Acquisition [PDF]
arXiv, 2020 Conventional word embeddings represent words with fixed vectors, which are usually trained based on co-occurrence patterns among words. In doing so, however, the power of such representations is limited, where the same word might be functionalized separately under different syntactic relations. To address this limitation, one solution is to incorporate

Discrete Word Embedding for Logical Natural Language Understanding [PDF]
arXiv, 2020 We propose an unsupervised neural model for learning a discrete embedding of words. Unlike existing discrete embeddings, our binary embedding supports vector arithmetic operations similar to continuous embeddings. Our embedding represents each word as a set of propositional statements describing a transition rule in classical/STRIPS planning formalism.
