Turing Test

From Wikipedia:The Turing test is a proposal for a test of a machine's ability to demonstrate intelligence. It proceeds as follows: a human judge engages in a natural language conversation with one human and one machine, each of which tries to appear human. All participants are placed in isolated locations. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test.

Pandorabots Components

– A Conversational Engine– A Web-based Interaction Interface

enabling users to interact with pandorabots

– A Programming Interface supporting knowledge development for pandorabots

– Systems supporting automatic knowledge generation for Pandorabots

The Conversational Engine

The Conversational Engine Component is an open-standard AIML engine implemented in Lisp.

In contrast to other open-standard AIML engine implementations, we developed a patented algorithm (independent of the programming-

language implementation) allowing for very efficient processing of simultaneous multiuser conversations between many pandorabots.

The Web-based Interaction

Through the Web-based Interaction Interface Component, the Conversational Engine supports conversational interactions between a variety of front-end programs (e.g. Flash, Jabber, irc, etc) and other web services (e.g. SecondLife). Standard Internet Protocols (http/xmpp, etc)chat through browsersan XML-RPC Application programming InterfaceFlexible to add new service

The Programming Interface

AIML programming code is used to create Conversational Knowledge. Programming Interface provides a software development environment facilitating AIML code development by non-programmers, in addition to supporting rapid development and modification of knowledge.

Pandorabots Knowledge

Conversational knowledge can be automatically generated from conversational transcripts.This technology component in the programming of Pandorabots Knowledge, enabling automatic/semi-automatic generation of conversational knowledge from dialogues to generate specific character types.
