In this paper, we introduce a new parser based on the Lexical-Functional Gram- mars formalism (LFG). This LFG parser accepts as input word lattices and computes functional structures on a shared forest. We also present various error recovery techniques we have im- plemented. Afterwards, we evaluate this parser on a large-coverage grammar for French in the framework of a large-scale use on various corpus. We show that our parser is both efficient and robust.
