UNL Dictionary

The UNL Dictionary, or UD, is the inventory of the permanent Universal Words. It is a flat list of UWs in alphabetical order with their corresponding semantic features, but without any further organization or structure, which is expected to be provided by the other UNL lexical databases (the UNL Knowledge Base and the UNL Memory, namely).

Subdivisions

The UNL Dictionary is divided into three nested repositories:

• The UNL Core Dictionary contains only permanent simple UWs that are (presumably) shared by all languages
• The UNL Abridged Dictionary contains all permanent UWs (simple, compound or complex) that are shared by at least two different language families
• The UNL Unabridged Dictionary contains all permanent UWs (simple, compound or complex) that are lexicalized in at least one language

Structure

The structure of the UNL Dictionary is defined by the Dictionary Specs.
