Introduction

What is Treex?

Treex (formerly TectoMT) was a highly modular NLP software system implemented in Perl programming language under Linux.

NOTE: Treex is not developed anymore (since ca 2017) and there are several better alternatives for most (though not all) of its original use cases:

• Udapi - a similar general framework, but much faster, UD-compliant and with Python (in addition to Perl) API
• UDPipe - UD-style tokenization, tagging, lemmatization and parsing for many languages, available both as a tool and online service
• MorphoDiTa - PDT-style morphological analysis
• Parsito - PDT-style dependency parsing
• Transformer - neural machine translation.

 

Treex is primarily aimed at Machine Translation, making use of the ideas and technology created during the Prague Dependency Treebank project. At the same time, it is also hoped to significantly facilitate and accelerate development of software solutions of many other NLP tasks, especially due to re-usability of the numerous integrated processing modules (called blocks), which are equipped with uniform object-oriented interfaces.

Applications

NLP Applications developed within the Treex NLP framework:

• TectoMT – English-to-Czech machine translation based on tectogrammatics
• Depfix – a system for rule-based correction of English-Czech statistical MT outputs
• HamleDT – harmonized dependency treebanks of 28 languages
