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 ...

Cleaning OCR'd text with Regular Expressions
The Programming Historian, 2013 Optical Character Recognition (OCR)—the conversion of scanned images to machine-encoded text—has proven a godsend for historical research. This process allows texts to be searchable on one hand and more easily parsed and mined on the other. But we’ve all

Understanding Regular Expressions
The Programming Historian, 2013 In this exercise we will use advanced find-and-replace capabilities in a word processing application in order to make use of structure in a brief historical document that is essentially a table in the form of prose.

Application of Regular Grammar in the Syntactic Analysis of Email Addresses
Ingeniería, 2023 Context: This article proposes the use of regular grammar as a strategy to validate the textual structures of emails. It focuses on the RFC 5321 standard and its syntax, formalizing regular grammars to apply production rules with the aim of validating ...

Beyond ωBS-regular Languages: ωT-regular Expressions and Counter-Check Automata [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 In the last years, various extensions of ω-regular languages have been proposed in the literature, including ωB-regular (ω-regular languages extended with boundedness), ωS-regular (ω-regular languages extended with strict unboundedness), and ωBS-regular ...

Helping tools for the regular expression author for test questions in LMS Moodle
Открытое образование (Москва), 2016 Composing regular expressions for test questions is often a difficult thing for the teachers; so many teachers avoid using regular expression questions. Similar problems hinder students learning regular expressions as a part of computer science.

The Complexity of Aggregates over Extractions by Regular Expressions [PDF]
Logical Methods in Computer Science, 2023 Regular expressions with capture variables, also known as regex-formulas, extract relations of spans (intervals identified by their start and end indices) from text.
