Probabilistic FastText for Multi-Sense Word Embeddings (P18-1)
Copied to clipboard
| Challenge: | Probabilistic FastText model for word embeddings captures word senses, sub-word structure, and uncertainty information. |
| Approach: | They propose a model for word embeddings that captures multiple word senses . they represent each word with a Gaussian mixture density, with each vector representing an n-gram . |
| Outcome: | The proposed model outperforms dictionary-level probabilistic embeddings on word-similarity benchmarks. |
Improving Implicit Discourse Relation Recognition with Semantics Confrontation (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing methods for implicit discourse relation recognition (IDRR) are unsatisfactory for the task. |
| Approach: | They propose a method that trains PLMs through two semantics enhancers to implicitly differentiate logical and general semantics. |
| Outcome: | The proposed method exceeds baseline by 3.81% F1 score on PDTB 2.0 dataset . it infers discourse logical relations without explicit connectives, but performance remains unsatisfactory . |
