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: "what s the point of documentation"
  Abstract: We give a brief characterisation of the purposes and forms of documentation in and of spreadsheets.

Connected through hyperedge HE-1 (induced by source paper "the reification of an incorrect and inappropriate spreadsheet model"):
  with members:
    - "evaluating financial model performance an empirical analysis of some north sea investments"
    - "reducing overconfidence in spreadsheet development"
    - "when why and how to test spreadsheets"
    - "recommended practices for spreadsheet testing"

Connected through hyperedge HE-2 (induced by source paper "a maintainability checklist for spreadsheets"):
  with members:
    - "complexity metrics for spreadsheet models"
    - "metrics based spreadsheet visualization support for focused maintenance"

Connected through hyperedge HE-3 (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"
    - "changing user attitudes to reduce spreadsheet risk"
    - "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"

Question: Please tell me which class the center node belongs to. 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.
