A Flexible Parser for a Linguistic Development Environment

We describe the parser of LEU/2, the Linguistic Experimentation Environment of the LILOG project. The parser is designed to support and encourage experimentation with different grammars, different styles of writing grammar, and with different parsing strategies. Unlike the parser of the first LILOG prototype, which was designed specifically for Categorial Unification Grammars (Uszkoreit 1986), the present parser places hardly any restrictions on the format of the grammar, and also supports rules in ID/LP-format (Gazdar et al. 1985) under two interpretations of LP statements. Empty categories can be processed. The parser includes a mechanism for processing unknown words, and for determining sentence boundaries in continuous text. The parser is a bottom-up chart parser for grammars encoded in STUF (Bouma, König, Uszkoreit 1988). Although the emphasis of the parser is on experimentation with different grammars rather than efficient analysis of texts, we have tried to make the parser as ...
