Abstract

Approximate searching using an index is an important application in many fields. In this paper we introduce a new data structure called the gapped suffix array for approximate searching in the Hamming distance model. Building on the well known filtration approach for approximate searching, the use of the gapped suffix array can improve search speed by avoiding the merging of position lists.
