Abstract
The third edition of the open challenge on Question Answering over Linked Data (QALD-3) has been conducted as a half-day lab at CLEF 2013. Differently from previous editions of the challenge, has put a strong emphasis on multilinguality, offering two tasks: one on multilingual question answering and one on ontology lexicalization. While no submissions were received for the latter, the former attracted six teams who submitted their systems’ results on the provided datasets. This paper provides an overview of QALD-3, discussing the approaches proposed by the participating systems as well as the obtained results.
