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: "the prose storyboard language a tool for annotating and directing movies"
  Abstract: The prose storyboard language is a formal language for describing movies shot by shot, where each shot is described with a unique sentence. The language uses a simple syntax and limited vocabulary borrowed from working practices in traditional movie-making, and is intended to be readable both by machines and humans. The language is designed to serve as a high-level user interface for intelligent cinematography and editing systems.

Connected through hyperedge HE-1 (induced by source paper "directing cinematographic drones"):
  with members:
    - "automated cinematography with unmanned aerial vehicles"
    - "airways optimization based planning of quadrotor trajectories according to high level user goals"
    - "generic drone control platform for autonomous capture of cinema scenes"
    - "towards a drone cinematographer guiding quadrotor cameras using visual composition principles"
