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: "point foundations of e democracy"
  Abstract: Considering the possibility of achieving an e-democracy based on long-established foundations that strengthen both real-world democracies and virtual Internet communities.

Connected through hyperedge HE-1 (induced by source paper "sybil resilient conductance based community growth"):
  with members:
    - "global cryptodemocracy is possible and desirable"
    - "being corrupt requires being clever but detecting corruption doesn t"
    - "sybil resilient reality aware social choice"
    - "incorporating reality into social choice"

Connected through hyperedge HE-2 (induced by source paper "foundation for genuine global identities"):
  with members:
    - "sybil resilient conductance based community growth"
    - "a survey on essential components of a self sovereign identity"
    - "sybil resilient reality aware social choice"

Connected through hyperedge HE-3 (induced by source paper "genuine personal identifiers and mutual sureties for sybil resilient community formation"):
  with members:
    - "a survey on essential components of a self sovereign identity"
    - "sybil resilient reality aware social choice"

Connected through hyperedge HE-4 (induced by source paper "aggregation over metric spaces proposing and voting in elections budgeting and legislation"):
  with members:
    - "on computing centroids according to the p norms of hamming distance vectors"
    - "incorporating reality into social choice"
    - "the complexity of multiwinner voting rules with variable number of winners"
    - "proportionally representative participatory budgeting axioms and algorithms"
    - "sequential deliberation for social choice"
    - "metric distortion of social choice rules lower bounds and fairness properties"
    - "the core of the participatory budgeting problem"
    - "iterative judgment aggregation"

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
