### Model Description |
|
|
|
The model classifies an *appraisal* given a sentence and is trained on [ALOE](https://huggingface.co./datasets/Blablablab/ALOE) dataset. |
|
|
|
**Input:** a sentence |
|
|
|
**Labels:** No Label, Pleasantness, Anticipated Effort, Certainty, Objective Experience, Self-Other Agency, Situational Control, Advice, Trope |
|
|
|
**Output:** logits (in order of labels) |
|
|
|
**Model architecture**: OpenPrompt_+RoBERTa |
|
