QALD-9-plus Dataset Description

QALD-9-plus is the dataset for Knowledge Graph Question Answering (KGQA) based on well-known QALD-9.

QALD-9-plus enables to train and test KGQA systems over DBpedia and Wikidata using questions in 10 different languages: English, German, Russian, French, Spanish, Armenian, Belarusian, Lithuanian, Bashkir, and Ukrainian.

Some of the questions have several alternative writings in particular languages which enables to evaluate the robustness of KGQA systems and train paraphrasing models.

As the questions' translations were provided by native speakers, they are considered as "gold standard", therefore, machine translation tools can be trained and evaluated on the dataset.

Dataset Statistics

	en	de	fr	ru	uk	lt	be	ba	hy	es	# questions DBpedia	# questions Wikidata
Train	408	543	260	1203	447	468	441	284	80	408	408	371
Test	150	176	26	348	176	186	155	117	20	150	150	136

Given the numbers, it is obvious that some of the languages are covered more than once i.e., there is more than one translation for a particular question. For example, there are 1203 Russian translations available while only 408 unique questions exist in the training subset (i.e., 2.9 Russian translations per one question). The availability of such parallel corpora enables the researchers, developers and other dataset users to address the paraphrasing task.

Evaluation

We used the GERBIL QA system for the evaluation of the dataset. The detailed information for the experiments is available at the individual link (click the value in the cells).
