title: LEARNING SEMANTIC WORD RESPRESENTATIONS VIA TENSOR FACTORIZATION
abstract: Many state-of-the-art word embedding techniques involve factorization of a cooccurrence
  based matrix. We aim to extend this approach by studying word embedding
  techniques that involve factorization of co-occurrence based tensors (N-
  way arrays). We present two new word embedding techniques based on tensor
  factorization and show that they outperform common methods on several semantic
  NLP tasks when given the same data. To train one of the embeddings, we present
  a new joint tensor factorization problem and an approach for solving it. Furthermore,
  we modify the performance metrics for the Outlier Detection Camacho-
  Collados & Navigli (2016) task to measure the quality of higher-order relationships
  that a word embedding captures. Our tensor-based methods significantly
  outperform existing methods at this task when using our new metric. Finally, we
  demonstrate that vectors in our embeddings can be composed multiplicatively to
  create different vector representations for each meaning of a polysemous word.
  We show that this property stems from the higher order information that the vectors
  contain, and thus is unique to our tensor based embeddings.
