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:

hmTEAMS Overview

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.
