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 "a web based ide for idp"):
  Abstract: IDP is a knowledge base system based on first order logic. It is finding its way to a larger public but is still facing practical challenges. Adoption of new languages requires a newcomer-friendly way for users to interact with it. Both an online presence to try to convince potential users to download the system and offline availability to develop larger applications are essential. We developed an IDE which can serve both purposes through the use of web technology. It enables us to provide the user with a modern IDE with relatively little effort.

Includes members:
  Member "visualising interactive inferences with idpd3":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "onlinesparc a programming environment for answer set programming")
  Member "predicate logic as a modeling language modeling and solving some machine learning and data mining problems with idp3":
    also connected through other hyperedges:
