A Regular Expression Matching Circuit Based on a Decomposed Automaton
In this paper, we propose a regular expression matching circuit based on a decomposed automaton. To implement a regular expression matching circuit, first, we convert regular expr...

Learning deterministic regular expressions for the inference of schemas from XML data
Inferring an appropriate DTD or XML Schema Definition (XSD) for a given collection of XML documents essentially reduces to learning deterministic regular expressions from sets of ...

Expressive Power of Non-Deterministic Operators for Logic-based Languages
Non-deterministic operators are needed in First-Order relational languages and Datalog to extend the expressive power of such languages and support efficient formulations of lowco...

Deterministic Expressions in C
Expressions in the programming language C have such an under-specified semantics that one might expect them to be non-deterministic. However, with the help of a mechanised formali...

A NFA-based programmable regular expression match engine
Pattern matching is the most computation intensive task of a network intrusion detection system (NIDS). In this paper we present a hardware architecture to speed up the pattern mat...
