Automated essay scoring with string kernels and word embeddings (P18-2)
Copied to clipboard
| Challenge: | Existing approaches to automatic essay scoring use low-level character n-gram features. |
| Approach: | They propose to combine string kernels and word embeddings for automatic essay scoring. |
| Outcome: | The proposed method outperforms state-of-the-art deep learning methods in Arabic dialect identification and native language identification tasks. |
Vector of Locally-Aggregated Word Embeddings (VLAWE): A Novel Document-level Representation (N19-1)
Copied to clipboard
| Challenge: | a novel word embedding representation for text documents is proposed . the method is based on the Vector of Locally-Aggregated Descriptors used for image representation . |
| Approach: | They propose a novel representation for text documents based on aggregating word embedding vectors into document embeddables. |
| Outcome: | The proposed representation improves on the Movie Review data set and is 10% better than the state-of-the-art representation. |
MOROCO: The Moldavian and Romanian Dialectal Corpus (P19-1)
Copied to clipboard
| Challenge: | Using the MOldavian and ROmanian Dialectal COrpus, we perform empirical studies on dialect identification tasks. |
| Approach: | They introduce the MOldavian and ROmanian Dialectal COrpus corpus which contains 33564 samples of text collected from the news domain. |
| Outcome: | The proposed model is based on a shallow and deep approach to discriminate between two different languages. |
