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: "changing user attitudes to reduce spreadsheet risk"
  Abstract: A business case study on how three simple guidelines: #R##N#1. Make it easy to check (and maintain) 2. Make it safe to use 3. Keep business logic out of code changed user attitudes and improved spreadsheet quality in a financial services organisation.

Connected through hyperedge HE-1 (induced by source paper "on the interpretation of spreadsheets within their environment"):
  with members:
    - "towards evaluating the quality of a spreadsheet the case of the analytical spreadsheet model"
    - "what s the point of documentation"
    - "documenting problem solving knowledge proposed annotation design guidelines and their application to spreadsheet tools"
    - "interpretation as a factor in understanding flawed spreadsheets"
    - "correctness is not enough"

Connected through hyperedge HE-2 (induced by source paper "leveraging user profile and behaviour to design practical spreadsheet controls for the finance function"):
  with members:
    - "spreadsheets the good the bad and the downright ugly"
    - "transforming critical spreadsheets into web applications at zurich financial"
    - "a practical approach to managing spreadsheet risk in a global business"
    - "controlling end user computing applications a case study"

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.
