+ Fine-tuned [mDeBERTa V3](https://huggingface.co/microsoft/mdeberta-v3-base) model for subjectivity detection in newspaper sentences.
11
+ This model was developed as part of the CLEF 2023 CheckThat! Lab [Task 2: Subjectivity in News Articles](https://checkthat.gitlab.io/clef2023/task2/).
12
+
13
+ The goal in this task is to detect whether a sentence is objective (OBJ) or subjective (SUBJ). A sentence is subjective if its content is based on or influenced by personal feelings, tastes, or
14
+ opinions. Otherwise, the sentence is objective. [(Antici et al., 2023)](https://ceur-ws.org/Vol-3370/paper10.pdf).

16
+ The model was fine-tuned using a multilingual training and Italian development dataset, for which the following (hyper)parameters were utilized:
17
+ ```
18
+ Batch Size = 32
19
+ Max Epochs = 2
20
+ Learning Rate = 5e-5
21
+ Warmup Steps = 300
22
+ Weight Decay = 0
23
+ ```

+ The model ranked first in the CheckThat! Lab and obtained a macro F1 of 0.76 and a SUBJ F1 of 0.65.
