Abstract
In this paper, we present a Natural Language Interface (NLI), which
combines some of the advantages of using general purpose grammars
with some of the features found in semantic grammars. This is achieved
by an Attribute Grammar so as to create an intermediate representation
which is interpreted in terms of domain-specific routines. NLI has
been used as a component of a Man-Machine Interaction (MMI) system,
working on different domains. After a discussion of the theory underlying
the system, two examples of the use of NLI on practical domains are
described: the first is in the field of three-dimensional scene generations,
the second in the field of road map car planning. Some evaluation
issues are also included in this paper.
