TLDR
This paper proposes a new variant of the bit-parallel NFA of Baeza-Yates and Navarro (BPD) for approximate string matching that is more efficient than the original BPD, and takes over/extends the role of theOriginal BPD as one of the most practical approximate string Matching algorithms under moderate values of k and m.

Bit-parallel approximate string matching algorithms with transposition

TL;DR: In this article, a uniform way of modifying each of these algorithms to permit also a fourth type of edit operation, transposing two adjacent characters in the pattern, is discussed, which is also known as the Damerau edit distance.

Hierarchical Parallelism of Bit-Parallel Algorithm for Approximate String Matching on GPUs

TL;DR: This paper proposes a hierarchical parallelism approach to accelerate the bit-parallel algorithm on NVIDIA GPUs and proposes to use hashing to reduce the memory usage and achieve 98.4% of memory reduction.

BEVA: An Efficient Query Processing Algorithm for Error-Tolerant Autocompletion

TL;DR: This article systematically study the query processing problem for error-tolerant autocompletion with a given edit distance threshold, and proposes a general framework that encompasses existing methods and characterizes different classes of algorithms and the minimum amount of information they need to maintain under different constraints.

Obtaining Precision-Recall Trade-Offs in Fuzzy Searches of Large Email Corpora

TL;DR: This chapter describes the design and implementation of cedas, a novel constrained edit distance approximate string matching algorithm that provides complete control over the types and numbers of elementary edit operations considered in approximate matches.

A guided tour to approximate string matching

TL;DR: This work surveys the current techniques to cope with the problem of string matching that allows errors, and focuses on online searching and mostly on edit distance, explaining the problem and its relevance, its statistical behavior, its history and current developments, and the central ideas of the algorithms.

A technique for computer detection and correction of spelling errors

TL;DR: The method described assumes that a word which cannot be found in a dictionary has at most one error, which might be a wrong, missing or extra letter or a single transposition.

Fast text searching: allowing errors

TL;DR: T h e string-matching problem is a very c o m m o n problem; there are many extensions to t h i s problem; for example, it may be looking for a set of patterns, a pattern w i t h "wi ld cards," or a regular expression.
