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 "monaa a tool for timed pattern matching with automata based acceleration"):
  Abstract: We present mmonaa, a monitoring tool over a real-time property specified by either a timed automaton or a timed regular expression. It implements a timed pattern matching algorithm that combines 1) features suited for online monitoring, and 2) acceleration by automata-based skipping. Our experiments demonstrate \monaa's performance advantage, especially in online usage.

Includes members:
  Member "efficient online timed pattern matching by automata based skipping":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "online quantitative timed pattern matching with semiring valued weighted automata")
  Member "montre a tool for monitoring timed regular expressions":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "f1 10 an open source autonomous cyber physical platform")
  Member "a boyer moore type algorithm for timed pattern matching":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "online quantitative timed pattern matching with semiring valued weighted automata")
