The UNL System comprises three different types of language resources: lexica, grammars and corpora. These resources have been provided mainly through the UNLarium.

Lexica

Main article: Lexica

In the UNL framework, there are two major types of lexical databases: monolingual and bilingual.

The monolingual resources are the following:

• in UNL
  • The UNL Dictionary, or simply UNL^dic, which is a flat list of UWs along with non-relational semantic features
  • The UNL Ontology, which is a hierarchy of UWs
  • The UNL Knowledge Base, or simply UNL^kb, which is a network with systematic relations between UWs
  • The UNL Example Base, or simply UNL^eb, which is a network with episodic relations between UWs
• in natural language
  • The NL Dictionary, or simply NL^dic, which is a list of natural language headwords

The bilingual resources are the following

• The UNL-NL Dictionary, or simply UNL-NL^dic, which is list of systematic lexical mappings between UNL and a given natural language
• The UNLization Memory, or UNL Memory Base, or simply UNL^MB, which is a list of mappings between UNL and a given natural language

Grammars

Main article: Grammar

Sets of rules to UNL-ize natural language documents and to NL-ize UNL documents, to be provided according to the Grammar Specs.

Corpora

Main article: Corpus

Documents written in UNL, to be provided according to the UNL document structure
