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 "query optimization properties of modified vbs"):
  Abstract: Valuation-Based~System can represent knowledge in different domains including probability theory, Dempster-Shafer theory and possibility theory. More recent studies show that the framework of VBS is also appropriate for representing and solving Bayesian decision problems and optimization problems. #R##N#In this paper after introducing the valuation based system (VBS) framework, we present Markov-like properties of VBS and a method for resolving queries to VBS.

Includes members:
  Member "beliefs in markov trees from local computations to local valuation":
    also connected through other hyperedges:
      (none)
  Member "from relational databases to belief networks":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a construction of bayesian networks from databases based on an mdl principle")
