Details of the hypergraph:
Center node: "towards log linear logics with concrete domains"
  Abstract: We  present#R##N#MEL#R##N#++#R##N#(M  denotes  Markov  logic  net-#R##N#works)  an extension  of  the log-linear  description  log-#R##N#ics#R##N#EL#R##N#++#R##N#-LL with concrete domains, nominals, and in-#R##N#stances. We use Markov logic networks (MLNs) in or-#R##N#der  to find the  most  probable,  classified and  coherent#R##N#EL#R##N#++#R##N#ontology from an#R##N#MEL#R##N#++#R##N#knowledge base. In#R##N#particular, we develop a novel way to deal with concrete#R##N#domains (also known as datatypes) by extending MLN’s#R##N#cutting plane inference (CPI) algorithm.

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.
