<p>We have a tag <a href="https://stats.stackexchange.com/questions/tagged/classification" class="post-tag" title="show questions tagged &#39;classification&#39;" rel="tag">classification</a>, which covers the more basic situation of two classes, but also that of <em>multiple</em> classes. The tag wiki is taken from <a href="https://en.wikipedia.org/wiki/Statistical_classification" rel="nofollow noreferrer">Wikipedia</a>:</p>
<blockquote>
<p>Statistical classification is the problem of identifying the sub-population to which new observations belong, where the identity of the sub-population is unknown, on the basis of a training set of data containing observations whose sub-population is known. Therefore these classifications will show a variable behavior which can be studied by statistics.</p>
</blockquote>
<p>However, we do get a number of questions on <em>multi-class</em> classification. <a href="https://stats.stackexchange.com/search?q=%5Bclassification%5D+multi">A simple search for &quot;multi&quot; in the &quot;classification&quot; tag currently returns 607 hits.</a></p>
<p>I am kind of wondering whether it would make sense to introduce a new tag like &quot;multi-classification&quot;. Or &quot;multi-class-classification&quot;, which sounds more correct but also more cumbersome - anything as long as the tag shows up when people start typing &quot;multi&quot;. Or do we assume that simply searching for &quot;multi&quot; in the &quot;classification&quot; tag is enough?</p>
<p>Thoughts, anyone?</p>
