Context-Aware Language Modeling for Goal-Oriented Dialogue Systems (2022.findings-naacl)
Copied to clipboard
| Challenge: | Goal-oriented dialogue systems face a trade-off between fluent language generation and task-specific control. |
| Approach: | They propose a method to fine-tune language models in a goal-aware way . they evaluate a flight-booking method with a context-assisted language model . |
| Outcome: | The proposed method outperforms the state-of-the-art method on a flight-booking task by 7% in terms of task success. |
Non-Programmers Can Label Programs Indirectly via Active Examples: A Case Study with Text-to-SQL (2023.emnlp-main)
Copied to clipboard
| Challenge: | Using APEL, non-programmers can annotate natural language utterances with complex programs that represent their meaning. |
| Approach: | They introduce a framework in which non-programmers select among candidate programs generated by a seed semantic parser. |
| Outcome: | The proposed framework achieves the same annotation accuracy as the original expert annotators (75%) and exposes many subtle errors in the original annotations. |
