The 6th BioASQ Workshop will be held as part of the Conference on Empirical Methods in Natural Language Processing (EMNLP) on November 1, 2018, at the Square Meeting Center in Brussels, Belgium. The venue located on the imposing Mont des Arts and having a broad vista over Brussels, sits in the historical and cultural heart of the city, very close to the centre of European government and is easily accessible through a variety of transportation options. It sits only two steps away from the capital's main transport hub, Central Station, which has a direct and fast train connection to Brussels Airport. Local train, tram, metro and bus lines all converge at Central Station, providing access to the entire city and rest of the country.
