FoR-UNL

FoR-UNL (Framework of Reference for UNL) is a guideline used to describe achievements of natural languages in relation to UNL. It was inspired by the Common European Framework of Reference for Languages (CEFR), and its main goal is to provide a method for assessing the availability and quality of natural language resources inside the UNL System.

Reference Levels

FoR-UNL divides languages into three broad divisions which can be divided into six levels:

• A - Basic Level
  • A1 - Breakthrough or beginner
  • A2 - Waystage or elementary
• B - Intermediate Level
  • B1 - Threshold or intermediate
  • B2 - Vantage or upper intermediate
• C - Advanced Level
  • C1 - Effective Operational
  • C2 - Mastery

Descriptors

The descriptors below inform what is required for a language to be classified in each level:

Level	UNL-NL Dictionary (entries)	NL-UNL Dictionary (entries)	UNL-NL Grammar (sentences)	NL-UNL Grammar (sentences)
A1	MIR-A1	BRUNO-A1	UC-A1	NC-A1
A2	MIR-A2	BRUNO-A2	UC-A2	NC-A2
B1	MIR-B1	BRUNO-B1	UC-B1	NC-B1
B2	MIR-B2	BRUNO-B2	UC-B2	NC-B2
C1	MIR-C1	BRUNO-C1	UC-C1	NC-C1
C2	MIR-C2	BRUNO-C2	RC-C2	NC-C2

Where:

• MIR is a project aiming the development of UNL-NL Dictionaries
• BRUNO is a project aiming the development of NL-UNL Dictionaries
• UC is the UNL Reference Corpus
• NC is the NL Reference Corpus

Assessment

• MIR: A subproject is considered completed when all its entries are either valid or reported as underspecified or overspecified. A dictionary entry is considered valid in MIR if created and verified both in the UNL-NL Dictionary and in the NL Dictionary.
• BRUNO: A subproject is considered completed when all its entries are valid. A dictionary entry is considered valid in BRUNO if created and verified in the NL Dictionary
• UC: A grammar is consider valid if its F-measure for the UNL Reference Corpus is equal or higher than 0.8.
• NC: A grammar is consider valid if its F-measure for the NL Reference Corpus is equal or higher than 0.8.
