A Large Self-Annotated Corpus for Sarcasm (L18-1)
Copied to clipboard
| Challenge: | Existing datasets for sarcasm detection have unbalanced and self-annotated labels, allowing for learning in both balanced and unbalanciated label regimes. |
| Approach: | They introduce the Self-Annotated Reddit Corpus (SARC) which has 1.3 million sarcastic statements and many times more instances of non-sarcasm statements. |
| Outcome: | The proposed corpus has 1.3 million sarcastic statements and many more instances of non-sarcasm statements, allowing for learning in both balanced and unbalanced label regimes. |
A La Carte Embedding: Cheap but Effective Induction of Semantic Feature Vectors (P18-1)
Copied to clipboard
| Challenge: | Existing word2vec-based methods for learning rare or unseen words have been criticized for degrading performance in small corpus settings. |
| Approach: | They propose a la carte embedding method that relies on a linear transformation that is efficiently learnable using pretrained word vectors and linear regression. |
| Outcome: | The proposed method is based on a new dataset showing that it can be used when a word is encountered even if only a single usage example is available. |
