human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "qoe beyond the mos an in depth look at qoe via better metrics and their relation to mos"
  Abstract: Quality of Experience, Mean Opinion, Score, Metrics, Statistics, Quantiles, Acceptability, Rating, distribution

Connected through hyperedge HE-1 (induced by source paper "subjective annotation for a frame interpolation benchmark using artifact amplification"):
  with members:
    - "memc net motion estimation and motion compensation driven neural network for video interpolation and enhancement"
    - "context aware synthesis for video frame interpolation"
    - "super slomo high quality estimation of multiple intermediate frames for video interpolation"
    - "video frame synthesis using deep voxel flow"
    - "gradient magnitude similarity deviation a highly efficient perceptual image quality index"
    - "ucf101 a dataset of 101 human actions classes from videos in the wild"

Connected through hyperedge HE-2 (induced by source paper "technical report on visual quality assessment for frame interpolation"):
  with members:
    - "context aware synthesis for video frame interpolation"
    - "video frame synthesis using deep voxel flow"
    - "ucf101 a dataset of 101 human actions classes from videos in the wild"

Connected through hyperedge HE-3 (induced by source paper "artificial intelligence paradigm for customer experience management in next generation networks challenges and perspectives"):
  with members:
    - "5g ultra dense cellular networks"
