    abstract = "We show that for each context-free grammar a new grammar can be constructed that generates a regular language. This construction differs from existing methods of approximation in that use of a pushdown automaton is avoided . This allows better insight into how the generated language is affected. The new method is also more attractive from a computational viewpoint."
