RT Journal Article T1 A Logical–Algebraic Approach to Revising Formal Ontologies: Application in Mereotopology A1 Aranda Corral, Gonzalo Antonio A1 Borrego Díaz, Joaquín A1 Chávez González, Antonia María A1 Gulayeva, Nataliya M. AB In ontology engineering, reusing (or extending) ontologies poses a significant challenge,requiring revising their ontological commitments and ensuring accurate representation and coherentreasoning. This study aims to address two main objectives. Firstly, it seeks to develop a methodologicalapproach supporting ontology extension practices. Secondly, it aims to demonstrate its feasibilityby applying the approach to the case of extending qualitative spatial reasoning (QSR) theories. Keyquestions involve effectively interpreting spatial extensions while maintaining consistency. Theframework systematically analyzes extensions of formal ontologies, providing a reconstruction ofa qualitative calculus. Reconstructed qualitative calculus demonstrates improved interpretativecapabilities and reasoning accuracy. The research underscores the importance of methodologicalapproaches when extending formal ontologies, with spatial interpretation serving as a valuable casestudy.
