Andrei Shapialevich enhanced the ostis-apps/geometry.ostis repository by expanding and formalizing its geometry knowledge base, focusing on triangle tasks and theorem notation. He applied ontology engineering and knowledge representation techniques to standardize terminology, reorganize formalizations, and introduce new geometric concepts, improving both content accuracy and maintainability. Using XML and semantic web technologies, Andrei refactored relations, unified identifiers, and aligned translations to support automated reasoning and easier onboarding for contributors. His work addressed ambiguity in theorem types by clarifying logical relationships, laying a foundation for scalable knowledge base development and more reliable downstream reasoning in geometry proofs.

In May 2025, delivered targeted terminology standardization in geometry theorem notation within ostis-apps/geometry.ostis. Renamed 'reverse' to 'inverse' and 'reverse converse' to 'contrapositive' to improve clarity and consistency in logical relationships. The work, tracked under commit 38cc1bf2ed477dcf0bea0529ab647f6de94ba4ad (fix notation for types of theorems), reduces ambiguity and lays groundwork for broader standardization. No major bugs fixed this month. Business impact includes improved maintainability, easier onboarding for contributors, and more reliable downstream reasoning in geometry proofs. Technologies/skills demonstrated include terminology standardization, traceable commits, impact assessment, and maintainable code changes.
