Deconstructing word embedding algorithms (2020.emnlp-main)
Copied to clipboard
| Challenge: | Word embeddings are reliable feature representations of words used in many NLP tasks today. |
| Approach: | They propose to deconstruct Word2vec, GloVe and others into a common form . they propose to generalize several word embedding algorithms into . a low rank embedder framework is proposed to generalise the algorithms into one common form. |
| Outcome: | The proposed framework can be used to make word embeddings more performant. |
Learning Efficient Task-Specific Meta-Embeddings with Word Prisms (2020.coling-main)
Copied to clipboard
| Challenge: | Word embeddings possess different lexical properties depending on the notion of context defined at training time. |
| Approach: | They introduce a meta-embedding method that learns to combine source embeddings according to the task at hand. |
| Outcome: | The proposed method improves performance on six extrinsic evaluations over other methods. |

| Challenge: | a dataset of over 7,000 tweets annotated with 5x coverage is used for sentiment analysis . a "complicated" class of sentiment is used to categorize text based on a predefined notion of sentiment . |
| Approach: | They propose to use a "complicated" class of sentiment to categorize tweets . they build a publicly available tweet sentiment analysis dataset . |
| Outcome: | The proposed classifiers perform better over a new publicly available TSA dataset . the classifier performance is compared with existing methods and improves on existing ones . |
