Game Theory Meets Embeddings: a Unified Framework for Word Sense Disambiguation (D19-1)
Copied to clipboard
| Challenge: | Word Sense Disambiguation (WSD) is an open problem in Natural Language Processing (NLP). |
| Approach: | They propose a game-theoretic model that embeds ambiguous words as players of a non cooperative game and their senses as strategies that the players can select in order to play the games. |
| Outcome: | The proposed model performs well on standard benchmarks and different tests on standard datasets. |

WiC: the Word-in-Context Dataset for Evaluating Context-Sensitive Meaning Representations (N19-1)
Copied to clipboard
| Challenge: | Existing word embeddings cannot model the dynamic nature of words’ semantics, i.e., the property of words to correspond to potentially different meanings. |
| Approach: | They propose a large-scale Word in Context dataset, called WiC, which is curated by experts and can be used to evaluate context-sensitive representations. |
| Outcome: | The proposed models outperform the standard evaluation dataset for the purpose and highlight their shortcomings. |
