“A Corpus for Complex Question Answering over Knowledge Graphs” elected as Paper of the month at FraunhoferIAIS

DOMfM_yX0AAQopVWe are very pleased to announce that our paper “A Corpus for Complex Question Answering over Knowledge Graphs” by Priyansh TrivediGaurav MaheshwariMohnish Dubey and Jens Lehmann has been elected as the Paper of the month at Fraunhofer IAIS. This award is given to publications that have a high innovation impact in the research field after a committee evaluation.

This research paper has been accepted on ISWC 2017 main conference and the paper presents a large gold standard Question Answering Dataset over DBpedia, and the accompanying framework to make the dataset. This is the largest QA dataset having 5000 questions, and their corresponding SPARQL query. This paper was nominated for the “Best Student Paper Award” in the resource track.

Abstract: Being able to access knowledge bases in an intuitive way has been an active area of research over the past years. In particular, several question answering (QA) approaches which allow to query RDF datasets in natural language have been developed as they allow end users to access knowledge without needing to learn the schema of a knowledge base and learn a formal query language. To foster this research area, several training datasets have been created, e.g.~in the QALD (Question Answering over Linked Data) initiative. However, existing datasets are insufficient in terms of size, variety or complexity to apply and evaluate a range of machine learning based QA approaches for learning complex SPARQL queries. With the provision of the Large-Scale Complex Question Answering Dataset (LC-QuAD), we close this gap by providing a dataset with 5000 questions and their corresponding SPARQL queries over the DBpedia dataset.In this article, we describe the dataset creation process and how we ensure a high variety of questions, which should enable to assess the robustness and accuracy of the next generation of QA systems for knowledge graphs.

The paper and authors were honored for this publication in a special event at Fraunhofer Schloss Birlinghoven, Sankt Augustin, Germany.
