UNL System

The UNL System consists of three main components:

• the UNL itself, i.e, the set of UW's, relations and attribute's, and the UNL Document Structure, which is the set of rules to combine them;
• the lingware, i.e., the set of lexical databases (dictionaries, knowledge bases and example bases) and grammars that are used to process the UNL and each natural language
• the software, i.e., the set of tools (for UNLization, NLization and normalization) and applications that can be generated thereafter.

Together they form the multilingual infrastructure that enables human communication across language barriers. Furthermore, thanks to this infrastructure, it is possible to create UNL applications and services in almost all fields of human activities.
