AGREE is a dataset and task for evaluation of language models based on grammar agreement in Czech. The dataset consists of sentences with marked suffixes of past tense verbs. The task is to choose the right verb suffix which depends on gender, number and animacy of subject. It is challenging for language models because 1) Czech is morphologically rich, 2) it has relatively free word order, 3) high out-of-vocabulary (OOV) ratio, 4) predicate and subject can be far from each other, 5) subjects can be unexpressed and 6) various semantic rules may apply. The task provides a straightforward and easily reproducible way of evaluating language models on a morphologically rich language.

The SQAD database consists of 3301 records obtained from Czech Wikipedia articles. The record structure is following:
- the original sentence(s) from Wikipedia
- a question that is directly answered in the text
- the expected answer to the question as it appears in the original text
- the URL of the Wikipedia web page from which the original text was extracted
- name of the author of this SQAD record
