[pandorabots-general] Bot Hosting

Hi Mehri,

It uses the graphmaster algorithm only the nodes are records in a database
instead of memory blocks.  You use a select statement in a stored procedure
at each node to get the matches just like you would use iterators or hashes
in memory.  Since the technique is stored procedures, the indexing is not
too much different than scanning in-memory objects (only much faster).
Actually the tables are probably in memory most of the time in the SQL
server, but it has a powerful mechanism to manage such things.  This beats
trying to do it yourself programmically paging in and out bots as they are
needed.

Your problem might be that you are trying to get the whole process into one
SQL statement.  In reality it is more like word-by-word.  When patterns are
not very long, the number of actual words compared is small.  So you might
perform maybe ten SQL statements on the average.

I have only a small computer running the demo and it swamps out easily.  So
be patient if you are trying to explore this using that resource.  As I've
said, the method is scaleable through a web farm and clustered servers.  My
$400 dollar PC and slow internet connection still can handle a couple of
conversation at a time.  A real server and database on separate machines
would fair much better.

BTW, I think, if I remember right, the example code has the first draft of
dynamic contexts which extend the power of <that> and <topic> to as many
contexts as you might wish.  The AIMLpad desktop has the contexts refined to
a stable extension.  Of course, contexts are just a short cut which standard
AIML can do without.

HTH,

True not all load the AIML entirely into memory at any
given time.

But an interpreter has to at least load part of the
AIML into memory to be able to get a response.  It
can't just entirely execute an SQL statement to get a
response.

Unless I missed out on someone being able to translate
the pattern matching algorithm of AIML purely into SQL
statements and a database schema without having to use
a Graphmaster algorithm.
