  proximate substring matching problem and our algorithms presented in this paper are the first work for the problem. Example 1.1.: Consider the string data in Figure 1. Sup-pose that the query string σ is ‘Jackson’ and k = 3. Since s1 has the substring which is exactly σ, its substring edit dis-tance to σ is 0.
