Regular Expressions with Lookahead [PDF]

open access: yesJUCS - Journal of Universal Computer Science, 2021
This paper investigates regular expressions which in addition to the standard operators of union, concatenation, and Kleene star, have lookaheads. We show how to translate regular expressions with lookaheads (REwLA) to equivalent Boolean automata having at most 3 states more than the length of the REwLA.

Effective Filter for Common Injection Attacks in Online Web Applications

open access: yesIEEE Access, 2021
Injection attacks against web applications are still frequent, and organizations like OWASP places them within the Top Ten of security risks to web applications. The main goal of this work is to contribute to the community with the design of an effective

Regular transducer expressions for regular transformations [PDF]

open access: yesInformation and Computation, 2018
Functional MSO transductions, deterministic two-way transducers, as well as streaming string transducers are all equivalent models for regular functions. In this paper, we show that every regular function, either on finite words or on infinite words, captured by a deterministic two-way transducer, can be described with a regular transducer expression ...

Scientific reference style using rule-based machine learning

open access: yesIJAIN (International Journal of Advances in Intelligent Informatics), 2023
Regular Expressions (RegEx) can be employed as a technique for supervised learning to define and search for specific patterns inside text. This work devised a method that utilizes regular expressions to convert the reference style of academic papers into

Generation of regular expressions for automata by the integral of regular expressions [PDF]

open access: yesThe 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.

A novel algorithm for the conversion of shuffle regular expressions into non-deterministic finite automata [PDF]

open access: yesMaejo International Journal of Science and Technology, 2013
Regular expressions with shuffle operators are widely used in diverse fields of computer science. The work presented here investigates the shuffling of regular expressions and their conversion into non-deterministic finite automata.

The use of syntax trees in order to automate the correction of LaTeX documents [PDF]

open access: yesКомпьютерные исследования и моделирование, 2012
The problem is to automate the correction of LaTeX documents. Each document is represented as a parse tree. The modified Zhang-Shasha algorithm is used to construct a mapping of tree vertices of the original document to the tree vertices of the edited ...
