The TreeAligner is a tool for work with parallel treebanks. The current version (1.2.3) runs on Windows, Linux and Mac OS X (only with MacPorts). This version supports:
- Browsing treebanks
- Creating new alignments
- Searching single and parallel treebanks
A parallel treebank consists of two corpora encoded with the TIGER XML Format, a file with word- and phrase-alignments.
For searching mono- and multilingual treebanks, the TreeAligner contains an implementation of the TIGER query language for annotated corpora. Additionally to the original features, it supports the following extensions:
- restricted universal quantification
- searching in treebanks annotated with frame semantics
