<p>How about this article from the same journal I suggested before?</p>

<p>Jeffrey L. Solka. Text data mining: Theory and methods. <em>Statistical Surveys</em> 2008; 2: 94-112. DOI: <a href="http://dx.doi.org/10.1214/07-SS016" rel="nofollow">10.1214/07-SS016</a></p>

<p>Reasons: open access, not very long (c. 12 pages of main text), not very mathematical (5 equations, no calculus or measure theory), seems quite a hot topic at the moment, I know nothing about it myself (so i'm not offering to 'present' it! In fact i doubt i can make the meeting this friday, sorry...)</p>
