human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "the memad submission to the wmt18 multimodal translation task"):
  Abstract: This paper describes the MeMAD project entry to the WMT Multimodal Machine Translation Shared Task. #R##N#We propose adapting the Transformer neural machine translation (NMT) architecture to a multi-modal setting. In this paper, we also describe the preliminary experiments with text-only translation systems leading us up to this choice. #R##N#We have the top scoring system for both English-to-German and English-to-French, according to the automatic metrics for flickr18. #R##N#Our experiments show that the effect of the visual features in our system is small. Our largest gains come from the quality of the underlying text-only NMT system. We find that appropriate use of additional data is effective.
