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 "clustering of musical pieces through complex networks an assessment over guitar solos"):
  Abstract: Musical pieces can be modeled as complex networks. This fosters innovative ways to categorize music, paving the way towards novel applications in multimedia domains, such as music didactics, multimedia entertainment and digital music generation. Clustering these networks through their main metrics allows grouping similar musical tracks. To show the viability of the approach, we provide results on a dataset of guitar solos.

Includes members:
  Member "on the modeling of musical solos as complex networks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on the complex network structure of musical pieces analysis of some use cases from different music genres")
  Member "guitar solos as networks":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the complex network structure of musical pieces analysis of some use cases from different music genres")
