The Free On-line Dictionary of Computing (30 December 2018):
infobot
    A bot that serves as a common database of information
   (often noteworthy URLs) for users on a chat system.
   Infobots often have a simple chatbot interface, responding
   to key-phrases, as well as to direct queries.
   Here, in a real conversation, the bot Purl's first response is
   triggered by the phrase "just tell me", and its second
   response is triggered by being directly asked "perlfunc?":
     can someone tell me what: $num9 =
           substr($number,9,1); means
     eesh -- man perlfunc, look at "substr".
     just tell me
     Didn't your momma ever tell you, "Go
           look it up in the dictionary"?!
     eesh -- no.  that's all we'll tell
           you.  read the documentation.
     eesh -- if you haven't man pages or
           perldoc, you can read them on the 'net.
     purl, perlfunc?
     well, perlfunc is Perl builtin
           functions, at man perlfunc or
           http://perl.com/CPAN-local/doc/manual/html/pod/perlfunc.html
   (http://cs.cmu.edu/~lenzo/infobot.html/).
