Details

• We trained a German question answering model with a gelectra-base 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 = 6536answers, because we removed 76 wrong answers.

Hyperparameters

lr_schedule = LinearWarmup
embeds_dropout_prob = 0.1

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.
