human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "the reaction ruleml classification of the event action state processing and reasoning space"):
  Abstract: Reaction RuleML is a general, practical, compact and user-friendly XML-serialized language for the family of reaction rules.

Includes members:
  Member "eca ruleml an approach combining eca rules with temporal interval based kr event action logics and transactional update logics":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "online event recognition from moving vehicles application paper")
  Member "xpath logic and xpathlog a logic programming style xml data manipulation language":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "querying xml documents in logic programming")
  Member "declarative semantics for active rules":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "verification validation and integrity of distributed and interchanged rule based policies and contracts in the semantic web")

Question: Please tell me which class the source paper 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.
