<p>As there are two tags, namely <a href="https://stats.stackexchange.com/questions/tagged/nlp" class="post-tag" title="show questions tagged &#39;nlp&#39;" rel="tag">nlp</a> and <a href="https://stats.stackexchange.com/questions/tagged/natural-language" class="post-tag" title="show questions tagged &#39;natural-language&#39;" rel="tag">natural-language</a>, I think the <a href="https://stats.stackexchange.com/questions/tagged/nlp" class="post-tag" title="show questions tagged &#39;nlp&#39;" rel="tag">nlp</a> tag can be merged in with the <a href="https://stats.stackexchange.com/questions/tagged/natural-language" class="post-tag" title="show questions tagged &#39;natural-language&#39;" rel="tag">natural-language</a> tag.</p>

<p><strong>Update:</strong> As @amoeba has clearly pointed out, <a href="https://stats.stackexchange.com/questions/tagged/nlp" class="post-tag" title="show questions tagged &#39;nlp&#39;" rel="tag">nlp</a> would be confusing as it can be both natural language processing and neuro-linguistic programming, so <a href="https://stats.stackexchange.com/questions/tagged/natural-language" class="post-tag" title="show questions tagged &#39;natural-language&#39;" rel="tag">natural-language</a> should be an apt tag.</p>
