Finding approximate occurrences of a query in a text using a full-text index is a central problem in stringology with many applications, especially in bioinformatics. The recent work has shown significant speed-ups by combining bidirectional indices and employing variations of search schemes . Search...
Approximate-String-MatchingApproximate-String-Matching (ASM) KAUST AMCS 260算法是一种用于字符串匹配的近似算法。它的主要思想是使用动态规划来求解问题,通过计算字符串之间的相似度来近似地判断两个字符串是否相等。 在KAUST AMCS 260算法中,首先将输入字符串转换为一个长度为n的二进制序列,然后对每一个字符进行...

Approximate String Matching with Address Bit Errors A string S∈Σm can be viewed as a set of pairs S={(σi,i):i∈{0,…,m1}}. We consider approximate pattern matching problems arising from the setting where ... A Amir,Y Aumann,O Kapah,... - Combinatorial Pattern Matching, Symposium...
2) approximate string matching 近似字符串匹配 1. Inapproximate string matching,the traditional edit distance cannot evaluate the similarity between strings very well,especially for the name and address datasets. 在近似字符串匹配中,传统的编辑距离不能很好地衡量诸如人名、地址等数据的相似关系,而块编辑距离...
Faster Approximate String Matching for Short Patterns We study the classical approximate string matching problem, that is, given\nstrings $P$ and $Q$ and an error threshold $k$, find all ending positions of\nsubstrings of $Q$ whose edit distance to $P$ is at most $k$. Let $P$ and ...
