CYMO functions as a powerful feature extractor, providing precise and objective operationalizations for vague CEFR "can-do" descriptors across all six proficiency levels—A1, A2, B1, B2, C1, and C2—while also extending beyond CEFR metrics to deliver a more comprehensive language proficiency assessment.

Comprehensive Feature Extraction and Objective Operationalizations
CYMO extracts a wide range of features, many of which provide precise and objective operationalizations for the often vague CEFR "can-do" descriptors. This includes metrics related to syntactic complexity, vocabulary diversity, sophistication, and richness, enabling accurate and detailed language proficiency assessments that go beyond traditional frameworks.
Detailed Analysis of Linguistic Complexity and Vocabulary Richness
CYMO captures features that reflect the depth and range of a learner's language skills, such as syntactic complexity and vocabulary diversity. These features provide a nuanced assessment of linguistic abilities, offering insights that are both detailed and reliable.
Cohesion, Stylistics, and Fine-Grained Proficiency Insights
Beyond syntactic and lexical analysis, CYMO also evaluates cohesion and stylistics, which are critical for assessing higher-level language proficiency. These features allow for a more comprehensive understanding of a learner's ability to produce coherent and stylistically appropriate language.
Sentence-Level Measurements
CYMO's feature extraction includes sentence-level measurements, providing a precise assessment of both readability and language proficiency. This approach offers a detailed evaluation that captures macro-level language abilities and micro-level sentence construction, delivering crucial insights for CEFR-aligned and broader assessments.
