<pause> []<br>

to get words after a pause (after a "begin-pause" literally, but you know the begin-pause actually represents the point-position of the pause).<br>

Subject: Re: [CWB] empty element<br>

<br>
> I have problems with a <pause></pause> xml tag in a spoken corpus.<br>

<br>
Exactly: CWB doesn't support empty XML elements, all s-attribute regions must enclose one or more tokens. And for good reason, as empty elements are a major pain in the corpus.<br>
<br>
> How do you suggest to solve this problem?<br>
<br>
BNCweb solves this problem by encoding such empty tags before the current token as a p-attribute, either in XML notation, e.g.<br>
<br>
<pause/><noise/><br>
<br>
or as a feature set<br>
<br>
|noise|pause|<br>
<br>
so it is easier to query for a specific tag, e.g with<br>
<br>
[tags_before contains "pause"]<br>
<br>
In fact, BNCweb stores _all_ XML tags (not just empty ones) before and after the current position in two separate p-attributes, which makes it a lot easier to reconstruct the original XML markup in the context display.<br>
<br>
Best,<br>
Stefan<br>
