Improving hash-q exact string matching algorithm with perfect hashing for DNA sequences

Comput. Biol. Medicine, 2021
Exact string matching algorithms involve finding all occurrences of a pattern P in a text T. These algorithms have been extensively studied in computer science, primarily because of their applications in various fields such as text search and ...

Generalized String Matching

SIAM Journal on Computing, 1987
Summary: Given a pattern string of length n and an object string of length m, the string matching problem asks for the positions of all occurrences of the pattern in the object string. This paper investigates a generalization of string matching, in which the pattern is a sequence of pattern elements, each compatible with a set of symbols.

Graphs Cannot Be Indexed in Polynomial Time for Sub-quadratic Time String Matching, Unless SETH Fails

Conference on Current Trends in Theory and Practice of Informatics, 2020
We consider the following string matching problem on a node-labeled graph $G=(V,E)$: given a pattern string $P$, decide whether there exists a path in $G$ whose concatenation of node labels equals $P$.

Analysis and safety engineering of fuzzy string matching algorithms.

ISA transactions, 2020
In this paper we explore fuzzy string matching in an automatic ticket classification and processing system. We compare performance of the following string similarity algorithms: Longest Common Subsequence (LCS), Dice coefficient, Cosine Similarity ...

Approximate String Matching

ACM Computing Surveys, 1980
Approximate matching of strings is reviewed with the aim of surveying techniques suitable for finding an item in a database when there may be a spelling mistake or other error in the keyword. The methods found are classified as either equivalence or similarity problems. Equivalence problems are seen to be readily solved using canonical forms.

String Matching on the Internet

2005
We consider a variant of the “string searching in database” problem where the string database comes on a data stream, and processing the data is at a premium but querying is not a runtime bottleneck. Speci.cally, the strings to be searched into (let's call them the documents) have to be processed online very e.ciently, meaning the documents have to be ...
