Task: Summarization
Input (English): Word embeddings extract semantic features of words from large datasets of text.
 Most embedding methods rely on a log-bilinear model to predict the occurrence
 of a word in a context of other words. Here we propose word2net, a method that
 replaces their linear parametrization with neural networks. For each term in the
 vocabulary, word2net posits a neural network that takes the context as input and
 outputs a probability of occurrence. Further, word2net can use the hierarchical
 organization of its word networks to incorporate additional meta-data, such as
 syntactic features, into the embedding model. For example, we show how to share
 parameters across word networks to develop an embedding model that includes
 part-of-speech information. We study word2net with two datasets, a collection
 of Wikipedia articles and a corpus of U.S. Senate speeches. Quantitatively, we
 found that word2net outperforms popular embedding methods on predicting held-
 out words and that sharing parameters based on part of speech further boosts
 performance. Qualitatively, word2net learns interpretable semantic representations
 and, compared to vector-based methods, better incorporates syntactic information.
Output (English): This paper extends SGNS with an architectural change from a bag-of-words model to a feedforward model, and contributes a new form of regularization by tying a subset of layers between different associated networks.
