Regular Expressions for language Engineering

Lauri Karttunen, Jean-Pierre Chanod, Greg Grefenstette, Anne Schiller
Many of the processing steps in natural language engineering can be performed using finite-state transducers. An optimal way to create such transducers is to compile them from regular expressions. This paper is an introduction to the regular expression calculus, extended with certain operators that have proved very useful in natural language applications ranging from tokenization to light parsing. The examples in the paper illustrate in concrete detail some of these applications.
