<div dir="ltr"><div>Hi Paul,<br><br></div><div>People more expert in the chart mapping rules and the grammar might want to chime in, but broadly speaking, your rule looks like it will work. There's a couple of ways you may run into issues:<br> <br></div><div> * if you input multiple tags for the same token, rules get complicated<br></div><div> * you may get unexpected results when the ERG native token is a multi-token entry (like "for example")<br></div> <div> * as I said before, sometimes the mapping between PTB and ERG types is not what you'd expect<br><br></div><div>But if you are limiting the places and tags where you try and restrict, you should be able to come up with a workable solution this way, I think.<br> <br></div><div>Rebecca<br></div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Sep 18, 2013 at 5:04 PM, Paul Haley <span dir="ltr"><<a href="mailto:paul@haleyai.com" target="_blank">paul@haleyai.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div text="#000000" bgcolor="#FFFFFF"> <div>Your comments have been quite helpful in getting me headed in what appears to be the right direction...<br> <br> I now think default LEs (whether none or only for gaps) has little bearing provided there is a tag provided (at least that is what I am observing in the behavior.)<br> <br> I have modified lfr.tdl as below and confirmed that I no longer get the native verbal LE for "array" provided any of NN, NNS, NNPS, NNP (it looks like I need to send $ instead of S for two of those, though.)<br> <br> What do you think?

Unfortunately, that's not in the mainstream PET release so far, because it is not that straightforward. There are several development implementations around that might do what you want, but they would all need to be configured to your particular set up. For one thing, the mapping from PTB tags isn't always clear-cut - the ERG lexical entries don't always align exactly with the PTB distinctions and so most (all?) work has been based on restricting by tags related to the lexical entries. As far as I know, there's no current implementations that can restrict by PTB POS tags, although others might know?<br> <br> </div> Rebecca<br> <div><br> <br> <br> <br> <br> </div> </div> <div class="gmail_extra"><br> <br> <div class="gmail_quote">On Wed, Sep 18, 2013 at 4:12 PM, Paul Haley <span dir="ltr"><<a href="mailto:paul@haleyai.com" target="_blank">paul@haleyai.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div text="#000000" bgcolor="#FFFFFF"> <div>I should correct my prior... <br> <br> It is not that the native LEs are taking precedence, but that native LEs that are not consistent with the input PoS are still being added to the chart. <br> <br> For example, if I pass in "array" with "NN", I'm still getting array_v1 in the chart.
