Definition
Native-language identification (NLI) is a subfield of natural language processing that focuses on recognizing the first language learned by a speaker. Unlike general language detection, NLI analyzes subtle linguistic features, accents, and syntactic patterns that persist even when speaking a second language. It is crucial for security applications, personalized user experiences, and sociolinguistic research, often employing deep learning models to capture nuanced phonetic and textual markers.
