For example, the annotation looks like the following:</div><div><br></div><div><br></div><div><div><div>(S1 (S (NP (PRP he))</div><div><br></div><div> (VP (MD can)</div><div><br></div><div> (NOT n't)</div><div><br></div><div> (VP (VB write)</div><div><br></div><div> (SBAR (WHADVP (WRB when)) (S (NP (PRP you)) (VP (VBP jump))))))</div><div><br></div><div> (. .)))</div></div></div><div><br></div><div>"he can't write when you jump.", (from the Brown-Adam corpus) where "when you jump" would be an embedded tensed clause because it's in an SBAR and "jump" has the node label VBP, which indicates non-3rd singular present tense (as compared to VB, which would be the non-tensed version).</div><div><br></div><div>This derived corpus is available through the CHILDES database in the derived corpora section (<a href="http://childes.psy.cmu.edu/derived/">http://childes.psy.cmu.edu/derived/</a> ) and also at our university website (<a href="http://www.socsci.uci.edu/~lpearl/CoLaLab/TestingUG/childestreebank.html">http://www.socsci.uci.edu/~lpearl/CoLaLab/TestingUG/childestreebank.html</a> ).</div><div><br></div><div>A tool that's useful for automatically searching through these kind of annotated trees is the Stanford NLP Group's tool Tregex, which is freely available here:</div><div><a href="http://nlp.stanford.edu/software/tregex.shtml#Download">http://nlp.stanford.edu/software/tregex.shtml#Download</a></div><div><br></div><div>-Lisa</div><br><div><div>On Aug 24, 2012, at 6:53 AM, <a href="mailto:info-childes@googlegroups.com">info-childes@googlegroups.com</a> wrote:</div><br><blockquote type="cite">

Subject: Detecting Embedded Tensed Clauses<br>
<br>
Hi,<br>
<br>
Using the various search protocols and meta-data levels, is it possible to<br>
detect embedded tensed clauses, i.e. embedded clauses with a tensed verb? I<br>
have been trying to create a combination of criteria, involving, e.g. CPRED,<br>
COMP, CJCT, CMOD, CPZR, etc., but with a low success rate.<br>
<br>
Any and all help would be greatly appreciated.<br>
<br>
Thanks,<br>
Adam<br>
<br>
