<p class="MsoNormal">When I read your second suggestion I had a light-bulb moment and decided to make "inf" an attribute of the "turn" tag (it is much better structurally and now I can show "turn_inf" in CQP, and hopefully visualize it in CQPWeb):<o:p></o:p></p>

<br>
That's because CWB doesn't support empty XML elements. It accepts the long from with explicit start and end tags, but will simply ignore the empty regions.<br>
<br>
In BNCweb, we store empty XML tags in a p-attribute that collects all tags that occur immediately before the respective token; a second p-attribute contains a pre-processed (feature set) representation for easier searching.<br>
<br>
Unfortunately, CQPweb can't visualize arbitrary p-attributes yet, so this would help for searching but nor display. I think the only work around would be to move the end tags so that the XML element wraps the following token:<br>
<br>
<turn><br>
<inf id="E"><br>
okay<br>
</inf><br>
ya<br>
son<br>
las<br>
horas<br>
ah<br>
</turn><br>
<br>
and then define a suitable visualization for the start tag <inf> in CQPweb, but not for the end tag </inf>.<br>
<br>
Best,<br>
Stefan<o:p></o:p></p>
