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 "leveraging multi method evaluation for multi stakeholder settings"):
  Abstract: In this paper, we focus on recommendation settings with multiple stakeholders with possibly varying goals and interests, and argue that a single evaluation method or measure is not able to evaluate all relevant aspects in such a complex setting. We reason that employing a multi-method evaluation, where multiple evaluation methods or measures are combined and integrated, allows for getting a richer picture and prevents blind spots in the evaluation outcome.

Includes members:
  Member "price and profit awareness in recommender systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "beyond personalization research directions in multistakeholder recommendation")
  Member "multisided fairness for recommendation":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "algorithmic fairness")
  Member "multiple stakeholders in music recommender systems":
    also connected through other hyperedges:
      (none)
