A conversational agent to help navigation and collaboration in virtual worlds

O. Bersot, P. -O. El Guedj, C. Godéreaux, P. Nugues
1998 Virtual Reality  
This paper describes the prototype of a conversational agent embedded within a collaborative virtual environment.  ...  It also accepts and executes commands to manipulate objects in the virtual world.  ...  We are implementing synchronisation rules to co-ordinate the agents and we are using reactive planning to make agents track moving entities.  ...

Intelligent social networks

Miguel Doctor, Ángel Moreno, Pablo Muñoz, Daniel Díaz, María Dolores R-Moreno
2011 Proceedings of the International Conference on Web Intelligence, Mining and Semantics - WIMS '11  
To build these new intelligent systems we propose to use Artificial Intelligence techniques, more concretely plan recognition.  ...  In addition, we present three scenarios where our system can be useful: Online commercial intentions, adaptive user interfaces and identity theft and extortion detection.  ...  Plan recognition or activity recognition aims to recognize the actions and goals of one or more agents from a series of partially observations on the agents' actions and the environmental conditions.  ...

Cognitive agent and its implementation in the blender game engine environment

Janusz A. Starzyk, Pawel Raif
2013 2013 IEEE Symposium on Computational Intelligence for Human-like Intelligence (CIHLI)  
We discuss both its organizational structure and tools we used to develop virtual implementation of the agent.  ...  Built in a virtual world, the agent is able to act autonomously, observe its environment and learn from its actions using principles of motivated learning.  ...  It facilitates simulation of such behaviors as learning how to move and control agents' virtual "body". An agent can interact with the environment using: sensors, actuators and controllers.  ...

The Road to Natural Conversational Speech Interfaces

Charles L. Ortiz
2014 IEEE Internet Computing  
A virtual personal assistant uses these recipes both in providing planning support to a user and in making sense of utterances during a dialog.  ...  This is a sort of planning process in reverse and is commonly referred to as plan or intention recognition.  ...
