KLcpos3 - a Language Similarity Measure for Delexicalized Parser Transfer

We present KLcpos3 , a language similarity measure based on Kullback-Leibler divergence of coarse part-of-speech tag trigram distributions in tagged corpora. It has been designed for multilingual delexicalized parsing, both for source treebank selection in single-source parser transfer, and for source treebank weighting in multi-source transfer. In the selection task, KLcpos3 identifies the bes...

Language engineering for syntactic knowledge transfer

In this paper we present a method for an English-Romanian treebank construction, together with the obtained evaluation results. The treebank is built upon a parallel English-Romanian corpus word-aligned and annotated at the morphological and syntactic level. The syntactic trees of the Romanian texts are generated by considering the syntactic phrases of the English parallel texts automatically r...

Cross-lingual Transfer Parsing for Low-Resourced Languages: An Irish Case Study

We present a study of cross-lingual direct transfer parsing for the Irish language. Firstly we discuss mapping of the annotation scheme of the Irish Dependency Treebank to a universal dependency scheme. We explain our dependency label mapping choices and the structural changes required in the Irish Dependency Treebank. We then experiment with the universally annotated treebanks of ten languages...

TIGER TRANSFER Utilizing LFG Parses for Treebank Annotation

Creation of high-quality treebanks requires expert knowledge and is extremely time consuming. Hence applying an already existing grammar in treebanking is an interesting alternative. This approach has been pursued in the syntactic annotation of German newspaper text in the TIGER project. We utilized the large-scale German LFG grammar of the PARGRAM project for semi-automatic creation of TIGER t...

TIGER TRANSFER From LFG Structures to the TIGER Treebank

Transfer Learning for Constituency-Based Grammars

In this paper, we consider the problem of cross-formalism transfer in parsing. We are interested in parsing constituencybased grammars such as HPSG and CCG using a small amount of data specific for the target formalism, and a large quantity of coarse CFG annotations from the Penn Treebank. While all of the target formalisms share a similar basic syntactic structure with Penn Treebank CFG, they ...
