Overview

Language model: gelectra-large-germanquad
Language: German
Training data: GermanQuAD train set (~ 12MB)
Eval data: GermanQuAD test set (~ 5MB)
Infrastructure: 1x V100 GPU
Published: Apr 21st, 2021

Details

  • We trained a German question answering model with a gelectra-large model as its basis.
  • The dataset is GermanQuAD, a new, German language dataset, which we hand-annotated and published online.
  • The training dataset is one-way annotated and contains 11518 questions and 11518 answers, while the test dataset is three-way annotated so that there are 2204 questions and with 2204·3−76 = 6536 answers, because we removed 76 wrong answers.

See https://deepset.ai/germanquad for more details and dataset download in SQuAD format.

Hyperparameters

Performance

We evaluated the extractive question answering performance on our GermanQuAD test set. Model types and training data are included in the model name. For finetuning XLM-Roberta, we use the English SQuAD v2.0 dataset. The GELECTRA models are warm started on the German translation of SQuAD v1.1 and finetuned on GermanQuAD. The human baseline was computed for the 3-way test set by taking one answer as prediction and the other two as ground truth. performancetable
