Eliza Chat bot

Do you want to chat with Eliza? Who is Eliza? Well, she: ELIZA, is a computer program and an early example of primitive natural language processing, with the limitations of the first conversational agents. She was written at MIT by Joseph Weizenbaum between 1964 and 1966. She is one of the classic chatterbots like:
  Dr. Sbaitso
  PARRY
  Racter or
  Mark V Shaney

Eliza is a conversation simulation. Specifically, she emulates a psychotherapist in the way she asks and answers your statements. For more info go to Eliza . There are many implementations of Eliza, Let me redirect you to one Chat with Eliza #1

Chatbot languages

A chatbot can converse in various language with humans. How many chatbots are in the world and what languages they are using, is a difficult question to answer. But, we can have some information from http://www.chatbots.org.

We can see in this website a summary by language:

As you can imagine, english is the most used language. However, we can see several chatbots talking some minority languages​​, but no less important as: Catalan, Swedish, or Danish.

Loebner Prize 2012: Play it again, Sam!



The 2012 Loebner Prize took place in Bletchley Park on Tuesday 15th May 2012 to mark Alan Turing's centenary celebrations.

What is the Loebner Prize?

The Loebner Prize for artificial intelligence ( AI ) is the first formal instantiation of a Turing Test. The test is named after Alan Turing the brilliant British mathematician. Among his many accomplishments was basic research in computing science. In 1950, in the article Computing Machinery and Intelligence which appeared in the philosophy journal Mind, Alan Turing asked the question "Can a Machine Think?" He answered in the affirmative, but a central question was: "If a computer could think, how could we tell?" Turing's suggestion was, that if the responses from the computer were indistinguishable from that of a human,the computer could be said to be thinking. This field is generally known as natural language processing.

NLP (Natural Language Processing) applied to chatbot development

NLP (natural language processing) is the key technology applied to chatbot development. There are three scripting languages used since nineties: AIML, Façade, and ChatScript.

The most famous bot using AIML (1995) has been A.L.I.C.E. (an extended version of Eliza). A.L.I.C.E. ("Artificial Linguistic Internet Computer Entity") won the annual Loebner Prize Competition in Artificial Intelligence. three times, and as well the Chatterbox Challenge Champion in 2004.

AIML is a XML dialect which was developed by Richard Wallace and a worldwide free software community between the years of 1995 and 2002. It is a kind of authoring system to build chatbots. The main characteristics are: categories, patterns, and templates. For more info: www.alicebot.org

FAÇADE (2005) was 10 years later. It was created by Michael Mateas and Andrew Stern. Began with Jess, a Java extension of the CLIPS expert-system language.  Jess allows you to declare and retract facts and have rules trigger when all of their preconditions match. Façade built on top of this a template script compiler that let them write NLP rules and compile them into Jess. If you want to read an article to compare with AIML and ChatScript, go here.

ChatScript (2010) was created by Bruce Wilcox. He won the 2010 Loebner Prize with Suzette, 2011 Loebner with Rosette, and 2nd in 2012 Loebner with Angela. The technology behind Outfit7's mobile app Tom Loves Angela and ESL chatbots at Japan's SpeakGlobal. 3rd place winner Chatbot Battles 2012 and awarded best 15 minute conversation prize. ChatScript aims to pattern-match on general meaning. For more info: sourceforge.net/projects/chatscript

RiveScript, the Artificial Intelligence Scripting Language

RiveScript language is an Artificial Intelligence Scripting Language used basically in developement of chatterbots and any conversatinal entitity. It is thought to be easier than other languages, i.e. AIML (Artificial Intelligence Markup Language).


RiveScript originally began as a Perl module called Chatbot::Alpha in 2004, programmed by Casey Kirsle. Kirsle had been working with chatterbots for a few years before then ... read more.
