FRAU (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 framework.

Reference Levels

FRAU 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 NL-UNL Dictionary UNL-NL Grammar NL-UNL Grammar
A1 2,000 2,000 500 500
A2 5,000 5,000 1,000 1,000
B1 10,000 10,000 2,000 2,000
B2 20,000 20,000 3,000 3,000
C1 35,000 35,000 5,000 5,000
C2 50,000 50,000 8,000 8,000

Where:

  • UNL-NL Dictionary is the number of UW's addressed in the UNL-NL dictionary according to the frequency of use. For instance: in order to achieve the level A1, languages must have addressed the 2,000 most frequent UW's (i.e., MIR A1)
  • NL-UNL Dictionary is the number of natural language lemmas addressed in the NL-UNL dictionary according to the frequency of use. For instance: in order to achieve the level A1, languages must have addressed their 2,000 most frequent lemmas (i.e., BRUNO A1)
  • UNL-NL Grammar is the number of UNL sentences of the UNL Reference Corpus that the languages are able to generate.
  • NL-UNL Grammar is the number of natural language sentences of the NL Reference Corpus that the languages are able to analyze.
