Structured Context and High-Coverage Grammar for Conversational Question Answering over Knowledge Graphs (2021.emnlp-main)
Copied to clipboard
| Challenge: | We present a new approach for weakly-supervised conversational Question Answering over Knowledge Graphs . |
| Approach: | They propose a Logical Form grammar that can model a wide range of queries on a Knowledge Graph while remaining sufficiently simple to generate supervision data efficiently. |
| Outcome: | The proposed grammar can model a wide range of queries while remaining simple to generate supervision data efficiently. |
Improving Compositional Generalization with Latent Structure and Data Augmentation (2022.naacl-main)
Copied to clipboard
| Challenge: | Generic unstructured neural networks struggle on out-of-distribution compositional generalization. |
| Approach: | They propose a method to recombinate examples from a model called Compositional Structure Learner and add them to a pre-trained sequence-to-sequence model. |
| Outcome: | The proposed model is even stronger than a T5-CSL ensemble on two real world compositional generalization tasks. |
