Sparse and Truncated Suffix Trees on Variable-Length Codes

  title={Sparse and Truncated Suffix Trees on Variable-Length Codes},
  author={Takashi Uemura and Hiroki Arimura},
The sparse suffix trees (SST), introduced by (Kärkkäinen and Ukkonen, COCOON 1996), is the suffix tree for a subset of all suffixes of an input text T of length n. In this paper, we study a special case that an input string is a sequence of codewords drawn from a regular prefix code ∆ ⊆ Σ recognized by a finite automaton, and index points locate on the code boundaries. In this case, we present an online algorithm that constructs the sparse suffix tree for an input string t on any variable… CONTINUE READING
