Conversational Agents: Goals, Technologies, Vision and Challenges

Merav Allouch, Amos Azaria, Rina Azoulay
2021 Sensors  
In recent years, conversational agents (CAs) have become ubiquitous and are a presence in our daily routines.  ...  Capable of conducting ongoing communication with humans, CAs are encountered in natural-language processing, deep learning, and technologies that integrate emotional aspects.  ...  The model is based on real-world data provided by a health clinic.  ...

An Architecture to Develop Multimodal Educative Applications with Chatbots

David Griol, Zoraida Callejas
2013 International Journal of Advanced Robotic Systems  
In this paper we present an architecture that facilitates building interactive pedagogical chatbots that can interact with students in natural language.  ...  However, in order for them to be widely employed and accepted as a learning resource, they must be easy to use and friendly.  ...  The valid range for this property is 0.0 (least sensitive to noise) to 1.0 (highly sensitive to quiet input).  ...
