This article describes a large-coverage formalisation of a French determiner system that includes simple words such as “le” (the), compounds such as “la plupart des” (most of), and more complex sequences such as “toute une partie de ce groupe de” (a whole part of this group of). The grammar is available in the form of a library of 150 Finite-State graphs and is compiled into a Minimal Deterministic Finite-State Transducer of over 5,000 states and 113,000 transitions.
