Copied to clipboard
| Challenge: | Existing studies on the process of building common ground have not been well conducted. |
| Approach: | They propose a method for recording the process of building common ground through a dialogue by using the intermediate result of a task. |
| Outcome: | The proposed method can record the building common ground process by using the intermediate result of a task and can be estimated quite accurately. |
Task-adaptive Pre-training of Language Models with Word Embedding Regularization (2021.findings-acl)
Copied to clipboard
| Challenge: | Pre-trained language models acquire domain-independent knowledge through pre-training with massive textual resources. |
| Approach: | They propose a task-adaptive pre-training process that makes static embeddings close to the word embedds obtained in the target domain. |
| Outcome: | The proposed process improves on BioASQ and SQuAD when the pre-training corpora were not dominated by indomain data. |
Investigating person-specific errors in chat-oriented dialogue systems (2022.acl-short)
Copied to clipboard
| Challenge: | Errors in general chatbots and chatbot that follow a rough persona have been studied . but those in chatbot based on real people have not been thoroughly investigated . |
| Approach: | They analyze dialogue data of a generation-based chatbot trained from dialogue data . they find errors in attributes and relations can be divided into two levels: self and other . |
| Outcome: | The results show that errors in chatbots can be divided into two types . the correspondence with an existing taxonomy of errors was also investigated . |
