Paralign: Automatic Parallel Text Alignment Tool

Paralign is an automatic parallel text alignment tool used for aligning sentences and words between two texts written in different languages. It can help prepare parallel corpora for machine translation systems.

What is Paralign?

Paralign is an open-source automatic parallel text alignment tool used for aligning sentences and words between two texts written in different languages. It utilizes statistical machine translation techniques to find the highest probability alignments between the sentences and words of the two texts.

Some key features of Paralign include:

• Alignment at both the sentence and word level
• Language independent implementation
• Tuning for precision or recall
• Output formats compatible with other NLP tools like Moses
• Both a graphical user interface and command line interface

Paralign is commonly used by computational linguists and machine translation researchers to prepare parallel corpora to train machine translation systems. It can significantly reduce the manual effort otherwise needed to create a sentence-aligned and word-aligned parallel text dataset. The automatic alignments still require some human validation and correction, but Paralign accelerates the process.

The software is written in Python and C++ and released under the GNU GPL license. It was originally created by Philipp Koehn but now has an active community of open source developers contributing to it.
