Multi-Relational Graph Transformer for Automatic Short Answer Grading (2022.naacl-main)
Copied to clipboard
| Challenge: | Existing methods for Automatic Short Answer Grading (ASAG) ignore structural context and therefore do not perform well. |
| Approach: | They propose a Multi-Relational Graph Transformer to prepare token representations considering the structural context of a sentence. |
| Outcome: | The proposed model outperforms existing state-of-the-art methods on a dataset from an undergraduate computer science course. |
Synthesizing Human Gaze Feedback for Improved NLP Performance (2023.eacl-main)
Copied to clipboard
| Challenge: | Prior work on eye tracking and NLP reveals that human scanpaths can aid in understanding and performance of NLP models. |
| Approach: | They propose a model for generating human scanpaths over text that approximates meaningful cognitive signals in human gaze patterns. |
| Outcome: | The proposed model can approximate meaningful cognitive signals in human gaze patterns. |
