A SILK Graphical UI for Defeasible Reasoning, with a Biology Causal Process Example

SILK is an expressive Semantic Web rule language and system equipped with scalable reactive higher-order defaults. We present one of its latest novel features: a graphical user interface (GUI) for knowledge entry, query answering, and justification browsing that supports user specification and understanding of advanced courteous prioritized defeasible reasoning. We illustrate the use of the GUI in an example from college-level biology of modeling and reasoning about hierarchically structured causal processes with interfering multiple causes.
