<div dir="ltr"><div>A correction: it turns out that Stanford CoreNLP uses tregex in dcoref, not tgrep. Quoting from the javadoc:<br><br>"A TregexPattern is a <code>tgrep</code>-type pattern for matching tree
node configurations. Unlike <code>tgrep</code> or <code>tgrep2</code>but like Unix
<code>grep</code>, there is no pre-indexing of the data to be searched.
Rather there is a linear scan through the trees where matches are sought.
As a result, matching is slower, but a TregexPattern can be applied
to an arbitrary set of trees at runtime in a processing pipeline."<br><br><a href="http://nlp.stanford.edu/nlp/javadoc/javanlp/edu/stanford/nlp/trees/tregex/TregexPattern.html">http://nlp.stanford.edu/nlp/javadoc/javanlp/edu/stanford/nlp/trees/tregex/TregexPattern.html</a><br>

I've been teaching it for years in my corpus linguistics course, but was considering replacing it with something else this year. Then I was digging around in the Stanford CoreNLP dcoref code and found that their filter for pleonastic "it" uses tgrep patterns. Now I'm rethinking whether or not to drop tgrep from my course. Is anyone else still using/teaching tgrep?<br>
