Multilingual Question Answering over Linked Data (QALD-3): Lab Overview

The third instalment of the open challenge on Question Answering over Linked Data (QALD-3) has been conducted as a half-day lab at CLEF2013. Di↵erently from previous editions of the challenge, QALD-3 put a strong emphasis on multilinguality, o↵ering 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 experimented by the participating systems as well as the obtained results.
