+This dataset provides a German dataset for DPR model training.
+DPR (Dense Passage Retrieval) is one of the most important components of RAG applications.
+Based on this dataset, German document retrieval models can be trained.
+
+The unique feature of this data set is that it contains not only training data for questions,
+but also imperative questions.
+An imperative question is a type of question that is phrased as a command or an instruction.
+Since there is a formal and informal form of address in German, both cases are included in the case of imperative questions.
