What is AIML

AIML stands for Artificial Intelligence Modelling Language. AIML is an XML based markup language meant to create artificial intelligent applications. AIML makes it possible to create human interfaces while keeping the implementation simple to program, easy to understand and highly maintainable.

History

The XML dialect called AIML was developed by Richard Wallace and a worldwide free software community between 1995 and 2002. AIML formed the basis for what was initially a highly extended Eliza called "A.L.I.C.E.." ("Artificial Linguistic Internet Computer Entity"), which won the annual Loebner Prize Competition in Artificial Intelligence three times, and was also the Chatterbox Challenge Champion in 2004. Because the A.L.I.C.E. AIML set was released under the GNU GPL, and because most AIML interpreters are offered under a free or open source license, many "Alicebot clones" have been created based upon the original implementation of the program and its AIML knowledge base. Free AIML sets in several languages have been developed and made available by the user community. There are AIML interpreters available in Java, Ruby, Python, C++, C#, Pascal, and other languages (see below). A semi-formal specification and a W3C XML Schema for AIML are available. Since early 2013, The A.L.I.C.E foundation has been working on a draft specification for AIML 2.0.

Java

Step 1 - Set up Java Development Kit (JDK)

You can download the latest version of SDK from Oracle's Java site − Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively.

Step 2 - Set up Program AB

Download the latest version of Program AB binaries from my Google drive using its program-ab-0.0.4.3 link.
Unzip the downloaded file and run "run.bat". Now it will load on command prompt

Python

Step 1 - Install Package

pip install python-aiml
The source code is available at Source Code

Simple Python Program

import aiml # Create the kernel and learn AIML files kernel = aiml.Kernel() kernel.learn("std-startup.xml") kernel.respond("load aiml b") # Press CTRL-C to break this loop while True: print kernel.respond(raw_input("Enter your message >> "))

Node JS

Step 1 - Install

npm install aiml
The source code is available at Source Code

Simple Program

var aiml = require('aiml') aiml.parseFile('sample.aiml', function(err, topics){ var engine = new aiml.AiEngine('Default', topics, {name: 'Jonny'}); var responce = engine.reply({name: 'Billy'}, "Hi, dude", function(err, responce){ console.log(responce); }); });

aiml

defines the beginning and end of a AIML document.
<aiml version = "1.0.1" encoding = "UTF-8"?> ... </aiml>

pattern

defines the pattern to match what a user may input to an Alicebot.
<category> <pattern> HELLO ALICE </pattern> <template> Hello User </template> </category>

template

defines the response of an Alicebot to user's input.
<category> <pattern> HELLO ALICE </pattern> <template> Hello User </template> </category>

star

Tag is used to match wild card * character(s) in pattern Tag.
<category> <pattern> A * is a *. </pattern> <template> When a <star index = "1"/> is not a <star index = "2"/>? </template> </category>

srai

Tag is a multipurpose tag. This tag enables AIML to define the different targets for the same template.
<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern> WHO IS ALBERT EINSTEIN </pattern> <template>Albert Einstein was a German physicist.</template> </category> <category> <pattern> WHO IS Isaac NEWTON </pattern> <template>Isaac Newton was a English physicist and mathematician.</template> </category> <category> <pattern>DO YOU KNOW WHO * IS</pattern> <template> <srai>WHO IS <star/></srai> </template> </category> </aiml>

random

Tag is used to get random responses. This tag enables AIML to respond differently for the same input. random tag is used along with li tags. li tags carry different responses that are to be delivered to the user on a random basis.
<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding ="UTF-8"?> <category> <pattern>HI</pattern> <template> <random> <li> Hello! </li> <li> Hi! Nice to meet you! </li> </random> </template> </category> </aiml>

li

li tags is used with random tag. li tags carry different responses that are to be delivered to the user on a random basis.<random> <li> pattern1 </li> <li> pattern2 </li> ... <li> patternN </li> </random>

set

set and get tags are used to work with variables in AIML. Variables can be predefined variables or programmer created variables.
<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern>I am *</pattern> <template> Hello <set name = "username"> <star/>! </set> </template> </category> <category> <pattern>Good Night</pattern> <template> Hi <get name = "username"/> Thanks for the conversation! </template> </category> </aiml>

get

set and get tags are used to work with variables in AIML. Variables can be predefined variables or programmer created variables.<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern>I am *</pattern> <template> Hello <set name = "username"> <star/>! </set> </template> </category> <category> <pattern>Good Night</pattern> <template> Hi <get name = "username"/> Thanks for the conversation! </template> </category> </aiml>

that

that Tag is used in AIML to respond based on the context.<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern>WHAT ABOUT MOVIES</pattern> <template>Do you like comedy movies</template> </category> <category> <pattern>YES</pattern> <that>Do you like comedy movies</that> <template>Nice, I like comedy movies too.</template> </category> <category> <pattern>NO</pattern> <that>Do you like comedy movies</that> <template>Ok! But I like comedy movies.</template> </category> </aiml>

topic

topic Tag is used in AIML to store a context so that later conversation can be done based on that context. Usually, topic tag is used in Yes/No type conversation. It helps AIML to search categories written within the context of the topic.<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern>LET DISCUSS MOVIES</pattern> <template>Yes <set name = "topic">movies</set></template> </category> <topic name = "movies"> <category> <pattern> * </pattern> <template>Watching good movie refreshes our minds.</template> </category> <category> <pattern> I LIKE WATCHING COMEDY! </pattern> <template>I like comedy movies too.</template> </category> </topic> </aiml>

think

think Tag is used in AIML to store a variable without notifying the user.<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern>My name is *</pattern> <template> Hello!<think><set name = "username"> <star/></set></think> </template> </category> <category> <pattern>Byeee</pattern> <template> Hi <get name = "username"/> Thanks for the conversation! </template> </category> </aiml>

condition

condition Tag is similar to switch statements in programming language. It helps ALICE to respond to the matching input.<?xml version = "1.0" encoding = "UTF-8"?> <aiml version = "1.0.1" encoding = "UTF-8"?> <category> <pattern> HOW ARE YOU FEELING TODAY </pattern> <template> <think><set name = "state"> happy</set></think> <condition name = "state" value = "happy"> I am happy! </condition> <condition name = "state" value = "sad"> I am sad! </condition> </template> </category> </aiml>
