+# Fine-tuned Flair Model on German NewsEye NER Dataset (HIPE-2022)
+
+This Flair model was fine-tuned on the
+[German NewsEye](https://github.com/hipe-eval/HIPE-2022-data/blob/main/documentation/README-newseye.md)
+NER Dataset using hmBERT Tiny as backbone LM.
+
+The NewsEye dataset is comprised of diachronic historical newspaper material published between 1850 and 1950
+in French, German, Finnish, and Swedish.
+More information can be found [here](https://dl.acm.org/doi/abs/10.1145/3404835.3463255).
+
+The following NEs were annotated: `PER`, `LOC`, `ORG` and `HumanProd`.
+
+# Results
+
+We performed a hyper-parameter search over the following parameters with 5 different seeds per configuration:
+
+* Batch Sizes: `[4, 8]`
+* Learning Rates: `[5e-05, 3e-05]`
+
+And report micro F1-score on development set:
+
+| Configuration     | Seed 1       | Seed 2         | Seed 3       | Seed 4       | Seed 5       | Average         |
