A Comparison of Two Paraphrase Models for Taxonomy Augmentation (N18-2)
Copied to clipboard
| Challenge: | a taxonomy is often used to look up concepts in text documents. |
| Approach: | They compare two state-of-the-art paraphrase models with a paraphrase dataset . they find that paraphrasing is a viable method to augment taxonomies with more terms . |
| Outcome: | The proposed model outperforms the previous model on the risk domain. |
attr2vec: Jointly Learning Word and Contextual Attribute Embeddings with Factorization Machines (N18-1)
Copied to clipboard
| Challenge: | popular word embeddings are used to learn vector representations from the context of words. |
| Approach: | They propose a framework for jointly learning embeddings for words and contextual attributes based on factorization machines. |
| Outcome: | The proposed framework improves on a text classification task compared to learning embeddings independently. |
