Native-language identification
open-in-new
<p>Native-language identification (NLI) is the task of determining an author's <a href="/facts/First_language/1yK3tnLb">native language</a> (L1) based only on their writings in a <a href="/facts/Second_language/aUqAzeNK">second language</a> (L2). NLI works through identifying language-usage patterns that are common to specific L1 groups and then applying this knowledge to predict the native language of previously unseen texts. This is motivated in part by applications in <a href="/facts/Second-language_acquisition/lkMLQsur">second-language acquisition</a>, language teaching and <a href="/facts/Forensic_linguistics/yCyUHkxy">forensic linguistics</a>, amongst others. </p>
