QAKiS: Question Answering wiKiframework-based System

Participants : Elena Cabrio, Julien Cojan, Amine Hallili, Serena Villata.

We worked on an extension of QAKiS, the system for open domain Question Answering over Linked Data, that allows to query DBpedia multilingual chapters. Such chapters can contain different information with respect to the English version, e.g. they provide more specificity on certain topics, or fill information gaps. QAKiS exploits the alignment between properties carried out by DBpedia contributors as a mapping from Wikipedia terms to a common ontology, to exploit information coming from DBpedia multilingual chapters (English, French and German), broadening therefore its coverage. We also worked on proposing an argumentation theory model to reason over the inconsistent information sets obtained from DBpedia multilingual chapters, and provide nevertheless a unique and motivated answer to the user.

A demo of the system is available online (http://qakis.org/qakis2/ ). The results of this research have been published in [26] , [27] , [54] , [34] .
