LX-DepParser

Provided by:
University of Lisbon (NLX-GROUP) - Natural Language and Speech Group, Department of Informatics, Faculty of Sciences

LX-DepParser performs the automatic parsing of sentences in Portuguese in terms of the grammatical functions of their words.

LX-DepParser output complies with the design options adopted for the construction of the CINTIL-DependencyBank.

The output of the parser can be obtained also in the format of Google's so-called Universal Dependencies, which results from the conversion of the original CINTIL output format by means of a set of regular expression rules over dependency trees, from which some residual distortion cases may happen to be introduced.

The analyses produced by LX-DepParser are similar to the dependency representations found in the CINTIL-DependencyBank on which LX-DepParser was trained. This dependency treebank was designed along the principles described in the following handbook: Branco António, Sérgio Castro, João Silva, Francisco Costa, 2011, CINTIL DepBank Handbook: Design options for the representation of grammatical dependencies.
