alud
alud is a Go package for deriving Universal Dependencies from Dutch sentences parsed with Alpino.
Overview
-
Alpino parses, POS-tags, lemmatizes and analyses morphologically any Dutch sentence that it is given. Alpino reliably analyses an input sentence syntactically, yielding a fully annotated syntactic tree with both constituents as well as explicitly labelled syntactic relations.
-
alud derives Universal Dependencies from Alpino's output (in XML, in the alpino_ds format), and writes it in the CoNLL-U format. Alternatively, output can be embedded into the alpino_ds format, making them available for XPath queries.
-
alud is also capable of inserting given Universal Dependencies into the alpino_ds format.
-
alud was based on a translation of an xquery script,
lassy2ud.
Universal Dependencies
Universal Dependencies (UD) is a programme that aims at cross-linguistically consistent tagging and dependency parsing. UD is an open community effort with over 500 contributors producing over 200 treebanks in over 100 languages. If you’re new to UD, you should start by reading the first part of the Short Introduction and then browsing the annotation guidelines on the UD website.
