+# Model Card for GalXLM-R for Semantic Role Labeling (cased)
+
+This model is fine-tuned on a version of [XLM RoBERTa Base](https://huggingface.co/xlm-roberta-base) and is one of 24 models introduced as part of [this project](https://github.com/mbruton0426/GalicianSRL). Prior to this work, there were no published Galician datasets or models for SRL. 
+
+## Model Details
+
+### Model Description
+
+GalXLM-R for Semantic Role Labeling (SRL) is a transformers model, leveraging XLM-R's extensive pretraining on 100 languages to achieve better SRL predictions for low-resource Galician. It was fine-tuned on Galician with the following objectives: 
+
+- Identify up to 13 verbal roots within a sentence.
+- Identify available arguments for each verbal root. Due to scarcity of data, this model focused solely on the identification of arguments 0, 1, and 2.
+
+Labels are formatted as: r#:tag, where r# links the token to a specific verbal root of index #, and tag identifies the token as the verbal root (root) or an individual argument (arg0/arg1/arg2)
+
+- **Developed by:** [Micaella Bruton](mailto:micaellabruton@gmail.com)
+- **Model type:** Transformers
+- **Language(s) (NLP):** Galician (gl)
+- **License:** Apache 2.0
+- **Finetuned from model:** [XLM RoBERTa Base](https://huggingface.co/xlm-roberta-base)
+
+### Model Sources 
+
+- **Repository:** [GalicianSRL](https://github.com/mbruton0426/GalicianSRL)
+- **Paper:** To be updated
+
+## Uses
+
+This model is intended to be used to develop and improve natural language processing tools for Galician.
+
+## Bias, Risks, and Limitations
+
+Galician is a low-resource language which prior to this project lacked a semantic role labeling dataset. As such, the dataset used to train this model is extrememly limited and could benefit from the inclusion of additional sentences and manual validation by native speakers.
+
+## Training Details
+
+### Training Data
+
+This model was fine-tuned on the "train" portion of the [GalicianSRL Dataset](https://huggingface.co/datasets/mbruton/galician_srl) produced as part of this same project.
+
+#### Training Hyperparameters
+
+- **Learning Rate:** 2e-5
+- **Batch Size:** 16
+- **Weight Decay:** 0.01
+- **Early Stopping:** 10 epochs
+
+## Evaluation
+
+#### Testing Data
+
+This model was tested on the "test" portion of the [GalicianSRL Dataset](https://huggingface.co/datasets/mbruton/galician_srl) produced as part of this same project.
+
+#### Metrics
+
+[seqeval](https://huggingface.co/spaces/evaluate-metric/seqeval) is a Python framework for sequence labeling evaluation. It can evaluate the performance of chunking tasks such as named-entity recognition, part-of-speech tagging, and semantic role labeling.
+It supplies scoring both overall and per label type.
+
+Overall:
+- `accuracy`: the average [accuracy](https://huggingface.co/metrics/accuracy), on a scale between 0.0 and 1.0.
+- `precision`: the average [precision](https://huggingface.co/metrics/precision), on a scale between 0.0 and 1.0.
+- `recall`: the average [recall](https://huggingface.co/metrics/recall), on a scale between 0.0 and 1.0.
+- `f1`: the average [F1 score](https://huggingface.co/metrics/f1), which is the harmonic mean of the precision and recall. It also has a scale of 0.0 to 1.0.
+
+Per label type:
+- `precision`: the average [precision](https://huggingface.co/metrics/precision), on a scale between 0.0 and 1.0.
+- `recall`: the average [recall](https://huggingface.co/metrics/recall), on a scale between 0.0 and 1.0.
+- `f1`: the average [F1 score](https://huggingface.co/metrics/f1), on a scale between 0.0 and 1.0.
