Use Case
The Computer Science Department at Columbia University conducted research detailed in the paper “ProLex: A Benchmark for Language Proficiency-oriented Lexical Substitution.” They aimed to develop a benchmark for evaluating systems that suggest higher proficiency level vocabulary substitutions in learners' writing, thereby enhancing the vocabulary diversity and writing proficiency of non-native English speakers.
And they used Cathoven to filter substitute words by their CEFR levels, ensuring that the substitutes were of equal or higher proficiency than the original words used by language learners.
Why CEFR Checker?
CEFR is the Common European Framework of Reference for Languages, an international standard for describing language ability. It is widely adopted for ESL (English as a Second Language) learners to assess and improve their language proficiency. Using a CEFR Checker allows educators and learners to measure progress and set learning goals based on recognized proficiency levels.
Why Choose Cathoven?
The Columbia University research team's priority was accuracy—particularly in context-sensitive CEFR level assessment.After a thorough comparison, Cathoven stood out as the only tool capable of delivering contextually accurate CEFR assessments.Unlike others that scale from A1 to C2, Cathoven further refines each level by splitting it into 10 additional segments.
The Columbia University research team even compiled a comparison report, including most CEFR checkers on the market, to demonstrate to the Computer Science department why Cathoven was the optimal choice.
