The UNL framework contains three different types of lexical databases: UNL, NL and UNL-NL.

UNL

There are three lexical databases in UNL:

  • The UNL Dictionary, or simply UNLdic, which is a flat list of UW's along with their semantic features
  • The UNL Knowledge Base, or simply UNLkb, which is a network with systematic relations between UW's
  • The UNL Example Base, or simply UNLeb, which is a network with any relations between UW's

These three databases are nested. The UNLdic contains UW's and their basic semantic features (such as lexical category, semantic class, abstractness, cardinality, etc.). The UNLkb contains the UNLdic and the set of relations that are necessary to define a UW (such as the information that "table" is a piece of furniture with vertical legs and a flat horizontal surface). The UNLeb contains the UNLkb and the set of relations that are often found between UW's (such as the information that tables are normally round or square, that are made of hard materials, etc.).

NL

  • The NL Dictionary, or simply NLdic, is a list of natural language headwords with the corresponding morphological and syntactic features.

UNL-NL

The bilingual resources are the following

  • The UNL-NL Dictionary, or simply UNL-NLdic, which is list of systematic lexical mappings between UW's and natural language entries
  • The UNLization Memory, or UNL Memory Base, or simply UNLMB, which is a list of mappings between UNL and a given natural language
