The KAVIAR tool aids domain experts in explicit knowledge representation using computer-assisted knowledge elicitation and machine learning. It includes quality measures for assessing classification and domain models, especially those from database machine learning.

Area of Science:

  • Artificial Intelligence
  • Knowledge Engineering
  • Machine Learning

Background:

  • Domain experts possess valuable implicit knowledge.
  • Explicit knowledge representation is crucial for AI and machine learning.
  • Existing tools may not adequately support knowledge elicitation and quality assessment.

Purpose of the Study:

  • To develop KAVIAR, a tool for making domain expert knowledge explicit.
  • To integrate computer-assisted knowledge elicitation and machine learning functionalities.
  • To implement robust quality assessment measures for developed models.

Main Methods:

  • Development of the KAVIAR tool.
  • Incorporation of knowledge elicitation components.
  • Integration of machine learning algorithms.
