Slot Attention with Value Normalization for Multi-Domain Dialogue State Tracking (2020.emnlp-main)
Copied to clipboard
| Challenge: | Existing dialogue state tracking approaches rely on ontology already defined, where all slots and their possible values are given. |
| Approach: | They propose a new architecture to exploit domain ontology by using Slot Attention and Value Normalization . they supplement the annotation of supporting span for MultiWOZ 2.1, which is the shortest span in utterances to support the labeled value. |
| Outcome: | The proposed architecture exploits ontology and can convert supporting spans to values. |
Leveraging Knowledge in Multilingual Commonsense Reasoning (2022.findings-acl)
Copied to clipboard
| Challenge: | Commonsense reasoning is a language-agnostic process, but most comprehensive knowledge sources are limited to a small number of languages, especially English. |
| Approach: | They propose to use English as a pivot language to integrate commonsense reasoning into models using a translate-retrieve-translate strategy. |
| Outcome: | The proposed model outperforms the state-of-the-art on the XCSR benchmarks. |
Training Data is More Valuable than You Think: A Simple and Effective Method by Retrieving from Training Data (2022.acl-long)
Copied to clipboard
| Challenge: | Experimental results show that REtrieving from the traINing datA only can lead to significant gains on multiple NLG and NLU tasks. |
| Approach: | They propose to retrieve training instances from traINing datA and concatenate them with input to generate output. |
| Outcome: | The proposed method achieves state-of-the-art results on XSum, BigPatent, and CommonsenseQA. |
