Artificial Intelligence - Chatterbot Eliza description


Artificial Intelligence - Chatterbot Eliza program is an Eliza like chatterbot.

This program is an Eliza like chatterbot.The implementation of the program has been improved, the repetitions made by the program are better handled, the context in a conversation is also better handled, the program can now correct grammatical errors that can occure after conjugating verbs.

Finaly, the database is bigger than the last time, it includes some of the script that originaly was used in the first implementation of the chatterbot Eliza by Joseph Weizenbaum. And also,most of the chatterbots that have been written this days are largely based on the original chatterbot Eliza that was written by Joseph Weizenbaum which means that they use some appropriate keywords to select the responses to generate when they get new inputs from the users.

More generaly,the techique that are in use in a "chatterbot database" or "script file" to represent the chatterbot knowledge is known as "Case Base Reasoning" or CBR. A very good example of an Eliza like chatterbot would be "Alice",these program has won the Loebner prize for most human chatterbot three times (www.alicebot.org).

The goal of NLP and NLU is to create programs that are capable of understanding natural languages and also capable of processing it to get input from the user by "voice recognition" or to produce output by "text to speech".

During the last decades there has been a lot of progress in the domains of "Voice Recognition" and "Text to Speech",however the goal of NLU that is to make software that are capable of showing a good level of understanding of "natural languages" in general seems quiet far to many AI experts. The general view about this subject is that it would take at list many decades before any computer can begin to really understand "natural language" just as the humans do.
