<div dir="ltr">Thanks everyone. I got this parse error a lot with toy grammars that I produced with the grammar matrix. I don't see lfr.tdl anywhere in those output grammars. Does anyone know what might be the grammar matrix equivalent?</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Dec 20, 2017 at 12:57 AM, Dan Flickinger <span dir="ltr"><<a href="mailto:danf@stanford.edu" target="_blank">danf@stanford.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div dir="ltr"> <div id="m_-3087037634506015501divtagdefaultwrapper" style="font-size:12pt;color:#000000;font-family:Calibri,Helvetica,sans-serif" dir="ltr"> <p style="margin-top:0;margin-bottom:0">Hi Olga,</p> <p style="margin-top:0;margin-bottom:0"><br> </p> <p style="margin-top:0;margin-bottom:0">This error message from ACE occurs when your grammar includes one or more token-mapping (preprocessing) rules which conspire to delete all of the edges from one of the cells in the initial parse chart, so that the parser cannot hope to find a covering analysis. 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_-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="h5"> <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_-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_-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.
