Question about Program E's matching engine

  • Jonathan Duay

    Jonathan Duay - 2003-02-14

    Im encountering problems with the matching on my program E bot.  The '*' inputs seem to have some sort of bug. for example, i have a pattern "feeding *", and I input 'feeding children', when i check the logs on the database, the input passed on is "feeding children children", thus resulting in no matches found. anyone here encounter any problems with the pattern matching engine???

      I've noticed the same problem. If * matches one word it works fine, but if it matches more than one word if repeats the extra words. for example:

      Input: what is one two three
      Pattern: what is *

      * is matched to: one two three two three

      This happens in version 0.08 but not version 0.07.

      BTW Is anyone still working on this thing?

      been doing a bit of playing, and I think I've fixed it, atleast for my problems

      in <b>src/graphnew.php</b>
      I added 1 character:

      used to be: $newword=fastforward($word,&$ffremains);

      is now: $newword=fastforward($word,<b>&</b>$ffremains);

      Seems to work for me, don't know if it's broken anything else though.

      Thanks for posting the solution above Richard although I think the HTML formatting went a bit screwy in your reply. Just to clarify for anybody else stuck on this - there appear to two lines in src/graphnew.php which require changing... at line 212 and 319 it currently says:

      which if changed to: $newword=fastforward($word,&$ffremains);

      seems to fix pattern matching for multiple words in *.

      I don't pretend to understand how this works, but I'm sure as hell enjoying creating AIML content for my bot to learn. Serious kudos to everybody involved in this project....

        Sorry to cross-post in the forum as well as in the 'Bugs' page, but I've been banging my head against a brick wall trying to debug some odd responses, when I noticed something odd...

        While the solution above seems to fix problems in categories containing only one <star />, I'm having problems with the following category:

        <pattern>* VERY *</pattern>
        <star index="1"/> <star index="2"/>

        Which is creating the following dialogue:
        User: I am very clever
        Bot: Very clever am very clever

        Anybody else come across this, or can help?!

          I'm using 0.9, and I have the same problem.  The '&' does nothing to help.

      I followed your suggestion and It fixed the problem of repeating words on my bot.
