Novel Feature Discovery for Task-Oriented Dialog Systems (2023.findings-eacl)
Copied to clipboard
| Challenge: | Prior work on novelty detection limits the scope of features represented by novel single intents to those represented by multiple user-perceived fine-grained features belonging to the same intent. |
| Approach: | They propose to use a feature discovery technique to discover novel features from user utterances rather than single intent discovery to classify them into slots. |
| Outcome: | The proposed approach consistently detects novel features from user utterances on two datasets. |
