<p class="MsoNormal"><span style="color:#1F497D;mso-fareast-language:EN-US">Thanks for the feedback on the dispersion feature. It’s still experimental, and various bits don’t quite work yet. So it is probably not you getting it wrong.

<p class="MsoNormal">Hi everybody (and in particular Andressa),<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">noticing the new Dispersion feature in CQPweb, I tried to play around with it, but I don't quite understand how to use it (and keep getting errors from the Web server if I do something too rash).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">My first mistake was not to wait long enough after starting the dispersion analysis (@Andrew: can we get one of your fancy "busy spinners" there, too?).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">With a relatively infrequent query term (which I picked to make the analysis faster), I get the following plot:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"><img width="2444" height="1732" style="width:25.4583in;height:18.0416in" id="B6DD0A0E-F602-43F6-B18B-8D50875B0EFE" src="cid:image001.png@01D52146.08C4CC00"><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">All the texts containing the search term end up clustered to the left instead of their normal position, which makes the plot very hard to read. Possibly a rendering issue with my browser (Firefox 67)?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">If I add a second query, the data points are also clustered to the left, though they don't occur exactly in the same texts (text overlap should be below 20%).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">When I tried to add a third query with more hits (ca. 19,000), MySQL ran at 100% CPU for several minutes, but I didn't see any result in the browser (perhaps a timeout?). Later, the DP and Juilland values do show up in the dispersion table.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">A fourth attempt adds points to the plot, but now the dispersion scores (and number of texts) are "undefined".<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is there documentation for the new feature? I'm clearly not using it correctly.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">One small bug: If I select "New query" from the menu at the top right, I get redirected to a completely wrong URL (which is missing the path to CQPweb on the server: in my case I get "<a href="http://127.0.0.1/corpus">http://127.0.0.1/corpus</a>"
instead of "<a href="http://127.0.0.1/cqpweb/corpus/">http://127.0.0.1/cqpweb/corpus/</a>").<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Best,<o:p></o:p></p>
