Alignment Tools for Parallel Treebanks

A Search Tool for Parallel Treebanks

This paper describes a tool for aligning and searching parallel treebanks. Such treebanks are a new type of parallel corpora that come with syntactic annotation on both languages plus sub-sentential alignment. Our tool allows the visualization of tree pairs and the comfortable annotation of word and phrase alignments. It also allows monolingual and bilingual searches including the specification...

Unsupervised Generation of Parallel Treebanks through Sub-Tree Alignment

e need for syntactically annotated data for use in natural language processing has increased dramatically in recent years. is is true especially for parallel treebanks, of which very few exist. e ones that exist are mainly hand-craed and too small for reliable use in data-oriented applications. In this paper we introduce an open-source system for fast and robust automatic generation of para...

XML-based Phrase Alignment in Parallel Treebanks

This paper describes the usage of XML for representing cross-language phrase alignments in parallel treebanks. We have developed a TreeAligner as a tool for interactively inserting and correcting such alignments as an independent level of treebank annotation.

Divergences in English-Hindi Parallel Dependency Treebanks

We present, here, our analysis of systematic divergences in parallel EnglishHindi dependency treebanks based on the Computational Paninian Grammar (CPG) framework. Study of structural divergences in parallel treebanks not only helps in developing larger treebanks automatically, but can also be useful for many NLP applications such as data-driven machine translation (MT) systems. Given that the ...
