![]() ![]() unknown.txt - if during a conversation with a user, the program hasn't found any keyword for a given sentence, the sentence is saved into this file.time records.txt is the file that holds the records of time delays in seconds that the program uses for simulating a human typist.script.txt is the file that stores the knowledge of the program.The code is pretty simple to understand, the most important part of the code can be found in the class that is named " Eliza". Most of the ideas that are in this code are directly inspired by the original chatterbot "Eliza" that was written by Joseph Weizenbaum. And finally, the "script file" ( script.txt) which acts as a knowledge base for the chatbot has been totally rewritten, and it is definitely better than in the previous versions of the program. This new version of the program is smarter than ever, more new features have been added since the last submission, and also now the conversation log between the users and the chatbot is automatically saved into the file: log.txt. This code is copyrighted, and has limited warranty. The general view about this subject is that it would take at least many decades before any computer can begin to really understand "natural language" just as humans do. However, the goal of NLU to make software that is capable of showing a good level of understanding of "natural languages", in general, seems to be quiet far to many AI experts. During the last few decades, there has been a lot of progress in the domains of "Voice Recognition" and "Text to Speech". 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". This program has won the Loebner prize for the most human chatterbot three times. ![]() The technique that is in use in a "chatterbot database" or "script file" to represent the chatterbot knowledge is known as "Case Base Reasoning" or CBR.Ī very good example of an Eliza like chatterbot would be " Alice". And also, most of the chatterbots that have been written these 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. The first chatterbot was published in 1966 by Joseph Weizenbaum, a professor of MIT. ![]() Bots like Eliza are the results of researches in Artificial Intelligence (more specifically, in NLP and NLU NLP: Natural Language Processing, NLU: Natural Language Understanding). This program is an Eliza like chatterbot. ![]()
