  title={On Constructing Suffix Arrays in External Memory},
  author={Andreas Crauser and Paolo Ferragina},
The construction of full-text indexes on very large text collections is nowadays a hot problem. The suffix array [16] is one of the most attractive full-text indexing data structures due to its simplicity, space efficiency and powerful/fast search operations supported. In this paper we analyze theoretically and experimentally, the I/O-complexity and the working space of six algorithms for constructing large suffix arrays. Additionally, we design a new external-memory algorithm that follows the… CONTINUE READING
