Stockholm TreeAligner - A tool for aligning and searching parallel treebanks. The Stockholm TreeAligner allows you to create alignment links between corresponding nodes (or words) in two treebanks in different languages.
The Stockholm TreeAligner allows you to create alignment links between corresponding nodes (or words) in two treebanks in different languages. This is useful for creating parallel treebanks, which have a wide array of linguistic applications, most notably machine translation.
The Stockholm TreeAligner displays trees from input files in TigerXML format with node labels, edge labels, and even crossing branches, making it useful for browsing TigerXML files as well.
As of version 0.8 (13. Dec. 2007) the Stockholm TreeAligner allows querying parallel treebanks (inspired by the TIGERSearch query language). Search results are highlighted in a graphical display.

The following screen shot shows a German tree and an English tree of the corresponding sentence. The nodes are aligned across the trees. Green lines stand for 'exact' translations while red lines stand for 'approximate' translations. The example contains node alignments and word alignments. We allow 1:n alignments (as e.g. in the alignment of German 'Heimweg' to English 'way home').

We gratefully acknowledge support by Granholmsstiftelsen 2005 and by the IIL program of the University of Zurich in 2009.
This software is a tribute to Maël Mettler who died unexpectedly in October 2007. His contributions to the software (the query module and indexing schemes) but even more his enthusiasm for our project will always be remembered. We have lost a friend.
