Evonne is web-based visualization tool for explaining reasoning. Within this project, we research and design visual explanations for logic and numerical reasoning. The main explanation component of Evonne is the interactive proof — a versatile explanation method that shows how an entailment can be derived from an ontology.
Online Demo & Examples:
- Demo of the tool: http://141.76.67.139:7007/
- User Studies Report: Report
- Benchmark resources: Concrete Domain explanations benchmark at NextCloud.
Source Code:
- Evonne lives in https://github.com/imldresden/evonne along with its installation instructions.
- Documentation: https://imldresden.github.io/evonne/
The latest update to Evonne focuses on combined logic and numerical reasoning. Entailments of this nature can be explained through combined proofs. However, considering the scalability requirements of the numerical reasoning, Evonne provides alternative visual explanations for numerical entailments. The numerical entailments supported in Evonne come from two Concrete Domains, dealing with linear equations and difference constraints, respectively.
Further Resources:
- Description Logics examples: DL examples at NextCloud.
- Ontology files: BioPortal snapshot and Modified Pizza Ontology.
