Title JavaScript Eliza
Author Gonzales Cenelia
Author Email cenelia [at] msn.com
Description Basicaly,these program is an "Eliza" like chatterbot,it
includes most of the features
that could normaly be found in chatterbots that are clone of "Eliza"
the
first
Chatbot program that was written by Joseph Weizenbaum professor of MIT
back in 1966.
However, the script that is, the database of input and responses is
different, also
i have implemented a special feature for controling repetitions that
the
program might make.
Also, the lookup() function that search for keywords inside the
database
of the program uses
the function "isGoodKey" that acts like an heuristic function for
selectioning the best keyword
that can be found in the database that match the current input.
