<p>It appears it has. I found two papers <a href="http://arxiv.org/abs/1211.0498" rel="nofollow">here</a> and <a href="http://acl.ldc.upenn.edu/N/N07/N07-2024.pdf" rel="nofollow">here</a>, and there are probably other. The second one was published at NAACL (a high-quality conference) and contains a bunch of relevant references.</p>
Has NLP ever been used to detect if someone is a native (English, or other) speaker?
<p>Are there any code samples or papers on the subject? I have not been able to find any resources directly related to the question after a bit of research.</p>
