• There can be differences in results of accepting cases like the below due to the gender and voice pitch of the AI agent of the chatbot or speech recognition AI-based system for public services. Check for any bias resulting from user interface and interaction method.
• Identify in advance and remove factors (e.g. presentation bias, ranking bias) that may create biases in designing and implementing user interfaces to prevent user interaction biases.
ü Presentation bias: This is a bias that occurs depending on how the information is represented. For instance, users can only click on content that is visible when using a product, and the click occurs only in the displayed content and not in other content. This kind of user interface can encourage clicks on only specific content.
ü Ranking bias: This is a bias that occurs depending on the order of information being presented. As users tend to think that the top results are the most relevant and important, the user’s selection frequency may be higher for results exposed at the top than those exposed at the bottom.
