Grammars and Programming Languages:
To Further Narrow the Gap
Paula S. Newman
Abstract
Symbolic parser/grammar combinations can be viewed as programming systems
for natural language processing applications. From this perspective, they
can be compared with conventional programming systems, and seen to require
more effort in the important development activities of testing and
debugging. This paper describes tools associated with the RH
(Retro-Hybrid) parser that facilitate these activities and are, to varying
extents, more broadly applicable. The paper also suggests a new approach
to improving parser efficiency using constrained inputs, based in part on
one of the RH debugging tools.
