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: "smartphones in mental health detecting depressive and manic episodes"
  Abstract: An observational study with patients diagnosed with bipolar disorder investigates whether data from smartphone sensors can be used to recognize bipolar disorder episodes and detect behavior changes that can signal an onset of an episode using objective data.

Connected through hyperedge HE-1 (induced by source paper "a survey of attention management systems in ubiquitous computing environments"):
  with members:
    - "productive anxious lonely 24 hours without push notifications"
    - "assessment of social roles for interruption management a new concept in the field of interruptibility"
    - "anticipatory mobile computing a survey of the state of the art and research challenges"

Connected through hyperedge HE-2 (induced by source paper "the tyranny of data the bright and dark sides of data driven decision making for social good"):
  with members:
    - "why should i trust you explaining the predictions of any classifier"
    - "measuring urban deprivation from user generated content"
    - "flooding through the lens of mobile phone activity"
    - "once upon a crime towards crime prediction from demographics and mobile data"
    - "daily stress recognition from mobile phone data weather conditions and individual traits"
    - "money walks a human centric study on the economics of personal mobile data"
    - "discrimination in online ad delivery"

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.
