hmTEAMS
Historic Multilingual and Monolingual TEAMS Models. The following languages are covered:
- English (British Library Corpus - Books)
- German (Europeana Newspaper)
- French (Europeana Newspaper)
- Finnish (Europeana Newspaper, Digilib)
- Swedish (Europeana Newspaper, Digilib)
- Dutch (Delpher Corpus)
- Norwegian (NCC Corpus)
Architecture
We pretrain a "Training ELECTRA Augmented with Multi-word Selection" (TEAMS) model:
Results
We perform experiments on various historic NER datasets, such as HIPE-2022 or ICDAR Europeana. All details incl. hyper-parameters can be found here.
Small Benchmark
We test our pretrained language models on various datasets from HIPE-2020, HIPE-2022 and Europeana. The following table shows an overview of used datasets.
| Language | Dataset | Additional Dataset |
|---|---|---|
| English | AjMC | - |
| German | AjMC | - |
| French | AjMC | ICDAR-Europeana |
| Finnish | NewsEye | - |
| Swedish | NewsEye | - |
| Dutch | ICDAR-Europeana | - |

Release
Our pretrained hmTEAMS model can be obtained from the Hugging Face Model Hub. Because of complicated license issues (that needs to be figured out), the model is only available by requesting access from Model Hub:
