This is an emotion classification model based on fine-tuning of a Bernice model, which is a pre-trained model trained on multilingual Twitter data. The fine-tuning dataset is a subset of the self-labeled emotion dataset (Lykousas et al., 2019) in English that corresponds to Anger, Fear, Sadness, Joy, and Affection. See the paper, LEIA: Linguistic Embeddings for the Identification of Affect for further details.
Evaluation
We evaluated LEIA-multilingual on posts with self-annotated emotion labels identified as non-English using an ensemble of language identification tools. The table below shows the macro-F1 scores aggregated across emotion categories for each language:
Language | Macro-F1 |
---|---|
ar | 44.18[43.07,45.29] |
da | 65.44[60.96,69.83] |
de | 60.47[57.58,63.38] |
es | 61.67[60.79,62.55] |
fi | 45.1[40.96,49.14] |
fr | 65.78[63.19,68.36] |
it | 63.37[59.67,67.1] |
pt | 57.27[55.15,59.4] |
tl | 58.37[55.51,61.23] |
tr | 45.42[41.17,49.79] |

visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
