and disambiguation of the named entities. We used the Stagger part-of-speech tagger to tag the documents and we implemented

a disambiguation module. We extracted and merged the answer candidates using their wikidata Q-number. This enables the

question-answering system to benefit from the synonymy facility of Wikipedia as... (More)
