Rewriting of regular expressions and regular path queries [PDF]
Proceedings of the eighteenth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems, 1999 AbstractRecent work on semi-structured data has revitalized the interest in path queries, i.e., queries that ask for all pairs of objects in the database that are connected by a path conforming to a certain specification, in particular to a regular expression.

Sound regular expression semantics for dynamic symbolic execution of JavaScript [PDF]
ACM-SIGPLAN Symposium on Programming Language Design and Implementation, 2018 Support for regular expressions in symbolic execution-based tools for test generation and bug finding is insufficient. Common aspects of mainstream regular expression engines, such as backreferences or greedy matching, are ignored or imprecisely ...

Forkable Regular Expressions [PDF]
, 2016 We consider forkable regular expressions, which enrich regular expressions with a fork operator, to establish a formal basis for static and dynamic analysis of the communication behavior of concurrent programs. We define a novel compositional semantics for forkable expressions, establish their fundamental properties, and define derivatives for them as ...

Generation of regular expressions for automata by the integral of regular expressions [PDF]
The Computer Journal, 1972 In this paper, the integral of regular expressions is defined and its properties are presented— The concept of the integral is then applied to establishing an algorithm for generating the regular expression of an arbitrary finite automaton specified by its state diagram or flow table.

Fast and Compact Regular Expression Matching [PDF]
, 2008 We study 4 problems in string matching, namely, regular expression matching, approximate regular expression matching, string edit distance, and subsequence indexing, on a standard word RAM model of computation that allows logarithmic-sized words to be ...

Derivatives of approximate regular expressions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 Automata, Logic and Semantics Our aim is to construct a finite automaton recognizing the set of words that are at a bounded distance from some word of a given regular language. We define new regular operators, the similarity operators, based on a generalization of the notion of distance and we introduce the family of regular expressions ...
