| A model for the Polish language has been trained on the [[http://clip.ipipan.waw.pl/LRT?action=AttachFile&do=view&target=NKJP-PodkorpusMilionowy-1.1.tgz|manually annotated subcorpus]] of the [[http://nkjp.pl/index.php?page=0&lang=1|National Corpus of Polish]]. An archive file with the model can be downloaded from [[attachment:model.zip|here]] ('''note''': you need version 0.4 of Concraft or higher to use it). The corpus has been first re-analysed with the [[http://nlp.pwr.wroc.pl/redmine/projects/libpltagger/wiki|Maca]] tool (using the `morfeusz-nkjp-official` configuration) and the same preprocessing pipeline should be used to prepare input data for morphosyntactic disambiguation. | We provide Concraft-pl models trained on the [[http://clip.ipipan.waw.pl/LRT?action=AttachFile&do=view&target=NKJP-PodkorpusMilionowy-1.1.tgz|manually annotated subcorpus]] of the [[http://nkjp.pl/index.php?page=0&lang=1|National Corpus of Polish]].

Concraft-pl
This page provides the official release of Concraft-pl, a morphosyntactic tagger for Polish based on constrained conditional random fields. The tool combines the following components into a pipeline:
A morphosyntactic segmentation and analysis tool Maca,
A morphosyntactic disambiguation library Concraft.

Downloads
Concraft-pl is available in a form of a software distribution which can be downloaded from Hackage using the Cabal tool. To compile Concraft-pl you will also need the Glasgow Haskell Compiler (GHC). The simplest way to get both Cabal and GHC is to install the Haskell Platform. Please see the documentation for more information about the installation process.
Pre-trained model
We provide Concraft-pl models trained on the manually annotated subcorpus of the National Corpus of Polish. Choose appropriate model depending on the version of Concraft-pl you are using.
