Frequently Asked Questions

Q: What is Quality Estimation (QE) in Machine Translation (MT) ?

A: Quality Estimation is an AI-driven methodology that predicts the quality of translation without relying on a human-reference gold standard. Lexicala’s QE models analyze linguistic precision and fluency in real-time, allowing organizations to automate quality control and flag translations that require human-in-the-loop review.

 

Q: How does Lexicala support under-resourced languages ?

A: We bridge the digital gap for under-resourced languages by combining our proprietary multilingual datasets with advanced linguistic engineering and training language experts. Using techniques like zero-shot learning and expert human curation, we develop high-performance models for languages that lack massive digital footprints, ensuring global innovation is truly inclusive. 

 

Q: Can Lexicala’s technology be integrated via API ?

A: Yes. All our language technology solutions, including customized Machine Translation and Quality Estimation, are designed for seamless API integration. This enables easy implementation into Generative AI workflows, NLP pipelines, and enterprise-level applications.
