Environnement Linguistique d'Unification
ELU (Environnement Linguistique d'Unification) is an enhanced PATR-II style
environment for linguistic development written and developed at ISSCO (see
Johnson and Rosner (1989), Russell et al. (1990), Estival et al. (1990)).
As its name indicates, ELU is based on unification and its purpose is the
development of computational linguistic applications in general. It
provides a declarative environment which allows linguists to write grammars
that can be used both for parsing and for generation. In addition to these
two standard functions of a linguistic development environment, ELU also
supports a transfer component. Together, these three components allow the
development of a system which can analyze a text in one language and
generate its translation in another language, making ELU particularly
suitable for experimenting with machine translation.
