LX-Gram is a grammar for the computational processing of Portuguese. It is being developed under the following major design features:

- precision: it is a precision grammar delivering accurate, linguistically grounded information of natural language sentences

- deep processing: it is a grammar for deep linguistic processing in as much as besides information on the major syntactic dimensions of grammatical constituency and dependency, it delivers (and generates from) fully-fledged logical representation of the meaning of natural language sentences

- large-scale: it is planned not to leave out any sort of regular grammatical construction or phenomena.

- multi-purpose: it is intended to make available as much linguistic information as it can possible be made explicit by automatic means, given the current state of the art in language technology, with the goal of offering itself to support the largest possible range of language technology applications.

LX-Gram is developed under the grammatical framework of Head-Driven Phrase Structure Grammar (Pollard and Sag, 1987, 1994) and uses Minimal Recursion Semantics (Copestake et al., 2005) for the representation of meaning.
The implementation of this grammar is undertaken with the grammar development environment Linguistic Knowledge Builder (Copestake, 2002). Its evaluation and regression testing is done via [incr tsdb()] (Oepen, 2001). It is also intended to be compatible with the PET parser (Callmeier, 2000).
The LinGO Grammar Matrix, version 0.9 2 (Bender et al., 2002) was used as the initial code upon which to build LX-Gram.
