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: "variations of the turing test in the age of internet and virtual reality"
  Abstract: Inspired by Hofstadter's Coffee-House Conversation (1982) and by the science fiction short story SAM by Schattschneider (1988), we propose and discuss criteria for non-mechanical intelligence:#R##N##R##N#We emphasize the practical requirements for such tests in view of massively multiuser online role-playing games (MMORPGs) and virtual reality systems like Second Life. In response to these new needs, two variations (Chomsky-Turing and Hofstadter-Turing) of the original Turing-Test are defined and reviewed. The first one is proven undecidable to a deterministic interrogator. Concerning the second variant, we demonstrate Second Life as a useful framework for implementing (some iterations of) that test.

Connected through hyperedge HE-1 (induced by source paper "on the universality of cognitive tests"):
  with members:
    - "complexity distribution of agent policies"
    - "a short note on estimating intelligence from user profiles in the context of universal psychometrics prospects and caveats"
    - "an approximation of the universal intelligence measure"
    - "the 3rd international planning competition results and analysis"

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.
