Area of Science:

  • Artificial Intelligence
  • Human-Computer Interaction
  • Information Visualization

Background:

  • User acceptance of knowledge-based systems is influenced by the clarity of their reasoning and conclusions.
  • Effective explanation mechanisms are crucial for the successful deployment of decision-support systems.

Purpose of the Study:

  • To introduce and illustrate the WOZ framework for generating effective explanations in component-based decision-support systems.
  • To demonstrate how the WOZ framework integrates various components for enhanced system transparency.

Main Methods:

  • The WOZ framework utilizes explicit models to represent explanations.
  • It employs a collection of visualization agents to present these explanations.
  • The framework integrates existing explanation strategies, component-based systems, graphical visualizations, and explicit models.
