About Me
I'm Stefan Zipproth, founder of acrion innovations GmbH in Switzerland. With over 25 years of experience in software development, I specialize in high-performance C++ solutions, semantic data processing, and open-source development.
Projects
zelph
zelph is a semantic network system designed to enhance data quality in large knowledge bases like Wikidata by:
- Identifying logical contradictions through rule-based inference
- Making deductions based on existing semantic relationships
- Processing the entire Wikidata knowledge graph (1.7 TB) efficiently
The system represents both facts and inference rules within the same semantic network, allowing for sophisticated reasoning about properties and relationships. You can explore the results at zelph.org.
Other Open Source Projects
- Cbeam - A modern, header-only C++ library for concurrency, memory management, and containers
- Ditana GNU/Linux - A customizable Arch-based Linux distribution
Contribution to Wikimedia Projects
I'm actively looking to contribute to the Wikidata ecosystem through tools that enhance data consistency and enable more sophisticated knowledge representation. My current focus is on integrating zelph's capabilities with Wikidata's existing infrastructure and community practices.
