Learning Lexical Subspaces in a Distributional Vector Space (2020.tacl-1)
Copied to clipboard
| Challenge: | Existing word embeddings that can cluster distributionally related words are weak, but they can be used to cluster words that might not be semantically similar. |
| Approach: | They propose a framework that injects lexical-semantic relations into distributional word embeddings by defining subspaces of the distributional vector space in which a lexically related relation should hold. |
| Outcome: | The proposed framework outperforms existing systems on relatedness and hypernymy tasks while being competitive on word similarity tasks. |
To Attend or not to Attend: A Case Study on Syntactic Structures for Semantic Relatedness (P18-1)
Copied to clipboard
| Challenge: | Recent success of Recurrent Neural Networks (RNNs) in Machine Translation (MT) has prompted attention mechanisms to be used in machine translation. |
| Approach: | They propose a tree-structured attention model on Tree Long Short-Term Memory Networks . they also experiment with three LSTM variants: bidirectional-LSTMs, Constituency Tree-LSTS, and Dependency Tree LSTS. |
| Outcome: | The proposed model is based on tree-LSTMs, constituency trees, and dependencies trees. |
