HI,
Can anyone tell me about AIML and how to implement it using PHP?
Thanks,

Hi,
I am also new this topic.

I have shared few things which i know, AIML, or Artificial Intelligence Markup Language, is an XML dialect for creating natural language software agents.

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 formal specification and a W3C XML Schema for AIML are available.

Elements of AIML
AIML contains several elements. The most important of these are described in further detail below.

1. Categories
2. Patterns
3. Templates

Categories in AIML are the fundamental unit of knowledge. A category consists of at least two further elements: the pattern and template elements. Here is a simple category:

When this category is loaded, an AIML bot will respond to the input "What is your name" with the response "My name is John."

A pattern is a string of characters intended to match one or more user inputs. A literal pattern like
will match only one input, ignoring case: "what is your name". But patterns may also contain wildcards, which match one or more words. A pattern like
will match an infinite number of inputs, including "what is your name", "what is your shoe size", "what is your purpose in life", etc.

The AIML pattern syntax is a very simple pattern language, far less complicated than regular expressions. It tends to suffice for most chat-oriented purposes, and where it lacks, AIML interpreters can provide preprocessing functions to expand abbreviations, remove misspellings, etc.

A template specifies the response to a matched pattern. A template may be as simple as some literal text, like
A template may use variables, such as the example
which will substitute the bot's name into the sentence, or
which will substitute the user's age (if known) into the sentence.

Template elements include basic text formatting, conditional response (if-then/else), and random responses.

Templates may also redirect to other patterns, using an element called srai. This can be used to implement synonymy, as in this example:
The first category simply answers an input "what is your name" with a statement of the bot's name. The second category, however, says that the input "what are you called" should be redirected to the category that matches the input "what is your name"--in other words, it is saying that the two phrases are equivalent.

Templates can contain other types of content, which may be processed by whatever user interface the bot is talking through. So, for example, a template may use HTML tags for formatting, which can be ignored by clients that don't support HTML.

Hi Jeyaseelan,
First of all I would like to say thanks for ur useful replies.

Is there any AIML interpreters avalilable for PHP?

Thanks,
Ramkumar.B

Hi,
I found the answer for this.

PROGRAM E is the AIML interpreter for PHP.

Thanks,
Ramkumar.B

Hi,
Another thing I would like to share with you.
As I heard, In future AIML will dominate the web.

Thanks,
Ramkumar.B

Hi,
Can you explain about BOT?

Thanks,
Ramkumar.B

HI,
A bot (short for "robot") is a program that operates as an agent for a user or another program or simulates a human activity. On the Internet, the most ubiquitous bots are the programs, also called spiders or crawlers, that access Web sites and gather their content for search engine indexes.

Thanks,

HI,

A chatterbot is a program that can simulate talk with a human being. One of the first and most famous chatterbots (prior to the Web) was Eliza, a program that pretended to be a psychotherapist and answered questions with other questions.

Hi,
Red and Andrette were names of two early programs that could be customized to answer questions from users seeking service for a product. Such a program is sometimes called a virtual representative or a virtual service agent.

HI,

A shopbot is a program that shops around the Web on your behalf and locates the best price for a product you're looking for. There are also bots such as OpenSesame that observe a user's patterns in navigating a Web site and customize the site for that user.

Thanks,
Ramkumar.B

HI,

A knowbot is a program that collects knowledge for a user by automatically visiting Internet sites and gathering information that meets certain specified criteria.

Thanks,

ACE
ACE means Artificial Conversation Entity. It is a program capable of listening to the user's speech, processing it, and then outputting a response. It is very basic, having three components to it: the listening engine, the ALICE engine, and the speaking engine

Thanks,
