PDB-based dependency parsing models for Polish

The PDB-based models are trained on the current version of Polish Depedency Bank with the publicly available parsing systems – COMBO, MateParser and MaltParser. MaltParser is a transition-based dependency parser that uses a deterministic parsing algorithm. The deterministic parsing algorithm builds a dependency structure of an input sentence based on transitions (shift-reduce actions) predicted by a classifier. The classifier learns to predict the next transition given training data and the parse history. MateParser, in turn, is a graph-based parser that defines a space of well-formed candidate dependency trees for an input sentence, scores them given an induced parsing model, and selects the highest scoring dependency tree as a correct analysis of the input sentence.

PDB-based MaltParser in Multiservice

• The performance of MaltParser model for Polish may be tested in Multiservice NLP – http://multiservice.nlp.ipipan.waw.pl.

• To parse a Polish text in Multiservice "Select predefined chain of actions": 5: Concraft, DependencyParser, input your text, and press the button "Run".

• To download the parser's output in CoNLL format, "Select output format:":
