POLFIE – an LFG grammar of Polish

POLFIE is an LFG grammar of Polish implemented in the XLE system (Xerox Linguistic Environment); it has been developed at the Institute of Computer Science, Polish Academy of Sciences (IPI PAN) within two projects: NEKST and CLARIN-PL. It provides a two-layer representation: constituent structure (c-structure, tree representation) and functional structure (f-structure, AVM representation). It is based on two previous implemented grammars of Polish: its c-structure is based on GFJP2, a DCG grammar used by the parser Świgra, while its f-structure is inspired by FOJP, an HPSG grammar of Polish. Lexical entries used by the grammar are created using Morfeusz, the state-of-the-art morphological analyser for Polish, Walenty, a valence dictionary of Polish, and selected converted valence dictionaries used by Świgra.

The grammar is made available according to the terms of GNU General Public License (version 3) unless stated otherwise.
