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 "text compression using abstract numeration system on a regular language"):
  Abstract: An abstract numeration system (ANS) is a numeration system that provides a one-to-one correspondence between the natural numbers and a regular language. In this paper, we define an ANS-based compression as an extension of this correspondence. In addition, we show the following results: 1) an average compression ratio is computable from a language, 2) an ANS-based compression runs in sublinear time with respect to the length of the input string, and 3) an ANS-based compression can be extended to block-based compression using a factorial language.

Includes members:
  Member "combinatorial characterization of formal languages":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "graph spectral properties of deterministic finite automata")
  Member "numeration systems on a regular language":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on subtrees of the representation tree in rational base numeration systems")
