HamleDT (HArmonized Multi-LanguagE Dependency Treebank) is a compilation of existing dependency treebanks (or dependency conversions of other treebanks), transformed so that they all conform to the same annotation style. This version uses Universal Dependencies as the common annotation style.
Update (November 1017): for a current collection of harmonized dependency treebanks, we recommend using the Universal Dependencies (UD). All of the corpora that are distributed in HamleDT in full are also part of the UD project; only some corpora from the Patch group (where HamleDT provides only the harmonizing scripts but not the full corpus data) are available in HamleDT but not in UD.
Lingua::Interset is a universal morphosyntactic feature set to which all tagsets of all corpora/languages can be mapped. Version 2.026 covers 37 different tagsets of 21 languages. Limited support of the older drivers for other languages (which are not included in this package but are available for download elsewhere) is also available; these will be fully ported to Interset 2 in future.
Interset is implemented as Perl libraries. It is also available via CPAN.
A tool for contrasting terminological vocabularies and textual corpora. It allows controlling the presence and location of reference vocabularies in textual corpora.
Multilingual lexical database that follows the model proposed by the EuroWordNet project. The MCR integrates into the same EuroWordNet framework wordnets from five different languages (together with four English WordNet versions). It also integrates WordNet Domains and new versions of the Base Concepts and Top Concept Ontology. Overall, it contains 1,642,389 semantic relations between synsets, most of them acquired by automatic means. Information contained: semantics, synonyms, antonyms, definition, equivalents, example of use, morphology.
