POLFIE: współczesna gramatyka formalna języka polskiego

This paper presents the new formal grammar of Polish, POLFIE , couched in Lexical Functional Grammar. The paper introduces the basics of LFG , discusses the way of representing syntactic structures in LFG and demonstrates the power of the LFG formalism on the basis of the analysis of selected phenomena of Polish in POLFIE. The paper shows that the LFG theory makes it possible to provide a formalised, adequate and linguistically deep description of syntactic phenomena such as: syntactic control, predicative arguments, the haplology of się, unbounded dependencies and coordination; it also takes into account interactions between these. POLFIE is accompanied by a computer implementation in XLE .
