Validated Scientific Metrics
LINGARA uses three complementary scientific metrics to ensure adaptation quality:
Flesch Reading Ease (FRE)
Definition: Readability metric developed by Rudolf Flesch, scoring reading ease on a scale of 0–100.
Formula: FRE = 206.835 – 1.015 × (words/sentences) – 84.6 × (syllables/words)
Recent Validation (2015–2025):
Jindal et al. (2017): Analysis of 249 health information studies
Will et al. (2025, JMIR): LLMs improve readability while maintaining accuracy
Alamleh et al. (2025): FRE suitable for AI-generated content
Flesch-Kincaid Grade Level (FKGL)
Definition: Metric developed by J. Peter Kincaid et al. estimating the U.S. school grade level required to understand text.
Formula: FKGL = 0.39 × (words/sentences) + 11.8 × (syllables/words) – 15.59
Scientific Basis: Developed for the U.S. Navy to assess technical manual readability; 0.90 correlation with reader comprehension
Recent Validation (2015–2025):
Stanford University (2024): LLMs improve formulaic readability measures in K–12 curricula
Risch et al. (2025): Validated in cancer education materials
Prykhodchenko et al. (2025): Adapting Flesch formulas to Ukrainian
Information Density Preservation (DIP)
Definition: Measures preservation of information during adaptation.
Formula: DIP = (Preserved Information / Original Information) × 100%
Scientific Basis: Based on Relevance Theory (Sperber & Wilson, 1986) and text simplification research (Siddharthan, 2014). Ensures essential information is not distorted or omitted.
Application: LINGARA validates DIP ≥ target for each profile (87–99%). If DIP < target, adaptation is rejected and LLM retries.

How does the cost of the project represent value for the Cardano ecosystem?
LINGARA offers an unprecedented combination of features that distinguish it from competitors and bring concrete advantages to the Cardano ecosystem. Unlike other solutions that rely on generic simplification, LINGARA adapts content for 15 specific cognitive profiles, making complex information accessible to a much broader audience.
Its methodology is grounded in robust scientific research, referencing 120 academic sources, while most competitors lack scientific validation. LINGARA ensures 100% preservation of critical information (DIP ≥ 90%), whereas other tools often lose essential content during adaptation.
The platform integrates natively with the Cardano blockchain, providing transparency, traceability, and verifiable proof of compliance—features absent in competing solutions. This enables:
Legal and regulatory compliance for Cardano-based organizations (e.g., EAA, WCAG 2.2).
Immutable certification of accessibility adaptations via NFTs.
On-chain verification of impact and usage metrics.
Decentralized identity management (DIDs) for users and organizations.
Additionally, LINGARA is fully open source (MIT License), giving the community freedom to use, modify, and contribute to the project. Privacy by design ensures no personal data is collected, aligning with Cardano’s ethos of security and user sovereignty.
For the Cardano community, this translates into:
Greater inclusivity – enabling 1.3 billion people globally to access Cardano content.
Enhanced adoption – removing cognitive and linguistic barriers for mass usage.
Stronger ecosystem credibility – providing legally verifiable accessibility solutions.
Alignment with Cardano’s social mission – measurable social impact via blockchain transparency.
This unique combination of cognitive accessibility, scientific rigor, blockchain integration, open-source availability, and privacy by design positions LINGARA as a strategic asset for the Cardano ecosystem.
