## Dataset Summary
|
| 108 |
|
| 109 |
+
**CliReNER<sub>gold</sub>** is a high-fidelity, expert-curated Named Entity Recognition (NER) dataset for the climate change research domain. Designed specifically as a gold-standard evaluation benchmark, it consists of 192 sentences annotated by a panel of 12 domain experts.

+
While the [*silver*](https://huggingface.co/datasets/P0L3/CliReNER_v_1_1_28_SILVER) version of this dataset is intended for model training, **CliReNER<sub>gold</sub>** serves as the authoritative ground truth for assessing model performance, ensuring high inter-annotator agreement and consensus through Weighted Expert Voting (WEV).

### Data Instances

- **Consensus Methodology (Weighted Expert Voting):** To resolve overlapping annotations from multiple experts, we applied a **Weighted Expert Voting (WEV)** scheme. Annotations from experts with domain-specific knowledge were weighted higher (w<sub>e</sub> = 1.1) than non-experts (w<sub>n</sub> = 0.9), with a deterministic two-stage voting process to resolve BIO boundary conflicts.
|
| 136 |
+
- **Agreement:** The final inter-annotator agreement among the 12 experts resulted in a Krippendorff's α of 0.6984. The WEV aggregation method showed high convergence with MACE probabilistic models (Cohen's κ = 0.9076).

## Limitations
|
| 139 |
|
| 140 |
+
- **Dataset Size:** As a high-fidelity evaluation set, the sample size (192 sentences) is smaller than the *silver* training set. It is primarily intended for evaluation rather than training.
|
| 141 |
+
- **Flat Schema:** Like the *silver* dataset, this follows a flat NER schema, meaning nested and discontinuous entities are excluded to prioritize consistency and reduce complexity.
