UNLization is the process of representing the content of a natural language structure into UNL. It may involve the following modules:
- The UNL Ontology
- The UNL Knowledge Base
- The UNL Memory
- The NL Memory
- The NL-UNL Dictionary
- The NL-UNL Memory
- The NL-UNL Transformation Grammar
- The NL-UNL Disambiguation Grammar

Modules
- Lexical Databases
- The UNL-NL Dictionary and the NL-UNL Dictionary contains mappings between UWs and natural language entries. It is a bilingual lexicon where UW's are translated into "lexical realisation units" of a given natural language, along with the minimal set of features necessary to differentiate between homonyms. As all open-class natural language entries are associated to UWs, the UNL-NL Dictionary also works as the pivot table that allows the alignment of all NL dictionaries.
- The UNL Ontology, the UNL Knowledge Base and the UNL Memory and the NL-UNL Dictionary contains semantic relations between UW's along with a degree of necessity, i.e., the possibility of occurrence. These repositories include ontological relations ("a kind of" and "an instance of"), in case of the UNL Ontology; necessary ontological and thematic relations (such as "is the agent of", "is the place where", "is the moment when"), in case of the UNL Knowledge Base; and typical ontological and thematic relations, in case of the UNL Memory.
- Grammars
- The UNL-NL D-Grammar and the UNL-NL T-Grammar are the set of rules used for natural language generation (out of UNL). The NL-UNL D-Grammar and the NL-UNL T-Grammar are the set of rules used for natural language analysis (to UNL). The T-Grammar is the repository of the transformation rules, which are used to manipulate data structures; the D-Grammar is the repository of disambiguation rules, which are used to control the use of transformation rules.
Specs
- Tagset
- The Tagset is a harmonized system for representing linguistic constants.
- Dictionary Specs
- The Dictionary Specs state the syntax of dictionaries.
- Grammar Specs
- The Grammar Specs state the syntax of grammar rules.
- KB Specs
- The UNL Knowledge Base Specs state the syntax of knowledge bases.
- Memory Specs
- The Memory Specs state the syntax of example bases.
