An Extendible Regular Expression Compiler for Finite-State Approaches in Natural Language Processing
Finite-state techniques are widely used in various areas of Natural Language Processing (NLP). As Kaplan and Kay [12] have argular expressions are the appropriate level of abstract...

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...

Hierarchical extraction of 3D interconnect capacitances in large regular VLSI structures
For submicron integrated circuits, 3D numerical techniques are required to accurately compute the values of the interconnect capacitances. In this paper, we describe an hierarchic...

Optimal Lower Bounds on Regular Expression Size Using Communication Complexity
The problem of converting deterministic finite automata into (short) regular expressions is considered. It is known that the required expression size is 2(n) in the worst case for ...
