<p>I am working on topic modeling and I am curious what exactly would be short text under this context?</p>

<p>The recent survey paper on short text topic modeling (by <a href="https://arxiv.org/pdf/1904.07695.pdf" rel="nofollow noreferrer">Qiang et al.</a>) mentions several datasets on which such models are evaluated: search snippets, StackOverflow question titles, tweets, and some others. The documents in these datasets have 5-14 words on average, and 14-37 words at maximum.</p>

<p>For example, if there is a research paper, would the research paper's title and abstract be considered as short text?</p>

<p>Paper abstracts that may have a bigger length. It is usual that the abstract has 200 or 300 words or even more.</p>
<p>The second argument that should be mentioned is that some short text topic modeling techniques assume that <em>each text has exactly one topic</em> (for example, in the paper by <a href="https://dl.acm.org/doi/pdf/10.1145/2623330.2623715" rel="nofollow noreferrer">Yin &amp; Wang</a>). I think it's possible that the abstract may have several topics in it. So, some of the models that assume one topic per one document may perform badly on paper abstracts.</p>
