For smaller grammars however the error will be from cases where the input sentence contains a word that is not in the lexicon (which is what I meant by a lexical gap). More specifically, there is a word for which a stem cannot be found in the lexicon using the existing orthographemic rules. Since Olga was talking about matrix regression testing I suspect this is her context.</div><span class="m_-3720151325719300329HOEnZb"><font color="#888888"><div><br></div><div>Woodley<br><br><br></div></font></span><div><div class="m_-3720151325719300329h5"><div><br>On Dec 20, 2017, at 9:38 AM, Kristen Howell <<a href="mailto:kphowell@uw.edu" target="_blank">kphowell@uw.edu</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">Thanks everyone.

For the ERG, this occasionally happens when I adjust the rules for inserting lexical entries for unknown words, and then try to filter some of those added entries in case I already have a "native" entry for that word. I imagine you must have one or more rules in a file like the ERG's "lfr.tdl" which discard some unwanted entries before parsing. Try commenting out these rules and see if the error message for that sentence disappears. You can see the error just by trying to parse that one sentence directly with ACE.</p> <p style="margin-top:0;margin-bottom:0"><br> </p> <p style="margin-top:0;margin-bottom:0"> Dan<br> </p> <br> <br> <div style="color:rgb(0,0,0)"> <hr style="display:inline-block;width:98%"> <div id="m_-3720151325719300329m_-5267281124168586687m_-3087037634506015501divRplyFwdMsg" dir="ltr"><font style="font-size:11pt" color="#000000" face="Calibri, sans-serif"><b>From:</b> <a href="mailto:developers-bounces@emmtee.net" target="_blank">developers-bounces@emmtee.net</a> <<a href="mailto:developers-bounces@emmtee.net" target="_blank">developers-bounces@emmtee.net</a><wbr>> on behalf of Olga Zamaraeva <<a href="mailto:olzama@uw.edu" target="_blank">olzama@uw.edu</a>><br> <b>Sent:</b> Tuesday, December 19, 2017 11:07 PM<br> <b>To:</b> Woodley Packard<br> <b>Cc:</b> <a href="mailto:developers@delph-in.net" target="_blank">developers@delph-in.net</a><br> <b>Subject:</b> Re: [developers] post-reduction lexical gap</font> <div> </div> </div><div><div class="m_-3720151325719300329m_-5267281124168586687h5"> <div>Hi Woodley,<br> <br> At a risk of asking a basic question: What does a lexical gap mean?<br> <br> Thank you,<br> Olga<br> <div class="m_-3720151325719300329m_-5267281124168586687m_-3087037634506015501x_gmail_quote"> <div dir="ltr">On Tue, Dec 19, 2017 at 9:35 PM Woodley Packard <<a href="mailto:sweaglesw@sweaglesw.org" target="_blank">sweaglesw@sweaglesw.org</a>> wrote:<br> </div> <blockquote class="m_-3720151325719300329m_-5267281124168586687m_-3087037634506015501x_gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div dir="auto"> <div>Hi all,</div> <div><br> </div> <div>This means ACE encountered a lexical gap.
