apertium-tagger-training-tools[edit]
Target-language driven part-of-speech tagger trainer
apertium-tagger-training-tools is an open-source package that can be used to train (in an unsupervised way) hidden-Markov-model-based part-of-speech taggers involved in machine translation. While training information, not only from the source language, but also from the target language is used; to this end the Apertium MT toolbox is used. After training a file containing the hidden-Markov-model parameters is produced; this file can be directly used within the Apertium MT toolbox. This package may simplify the initial building of an Apertium-based machine translation system for a new pair of languages.

apertium-transfer-tools[edit]
Automatic shallow-transfer rules generation from parallel corpora
apertium-transfer-tools is an open-source package consisting of a set of tools that allow the automatic generation of Apertium (level 1) transfer rules from parallel corpora. Transfer rules are generated from alignment templates, like those used in statistical machine translation, that have been extracted from parallel corpora and extended with a set of restrictions controlling their application.
The generated transfer rules (in XML format) can be directly used by the Apertium MT platform. Although this package is aimed at the generation of Apertium transfer rules it can be adapted to generate shallow-transfer rules for other MT platforms; moreover, some of the tools it provides can be used for other purposes such as the extraction of bilingual phrase pairs or the symmetrization of previously computed alignments. This package depends on the GIZA++ toolkit to compute word alignments; nevertheless, it can be easily adapted to use other aligners.

apertium-eval-translator[edit]
Evaluation of Apertium-based MT systems
apertium-eval-translator is a very simple script written in Perl. It calculates the word error rate (WER) and the position-independent word error rate (PER) between a translation performed by an Apertium-based MT system and its human-corrected translation at document level. Although it has been designed to evaluate Apertium-based systems, it can be easily adapted to evaluate other MT systems.

apertium-tinyLex[edit]
dictionary look-up for mobile devices
apertium-tinylex is an open-source J2ME (Java 2 Micro Edition) program that can be used to translate words. The program is currently available for mobile devices supporting MIDP 2.0 and there is already a (beta 0.2) version for almost all language pairs in Apertium. It is intended to add further features in future releases.
