How Does the Catile Score Work?
Catile evaluates texts based on four key factors:
- Decoding Ease — Measures how easy it is for readers to decode the text.
- Vocabulary Familiarity — Assesses the complexity and familiarity of the words used.
- Sentence Complexity — Looks at the structural difficulty of sentences.
- Repetition Patterns — Analyzes how often structures or words repeat, influencing comprehension.
This comprehensive approach provides a richer understanding of text complexity than a single numeric score alone.
