Promptdiff: a fixed-point algorithm for comparing ontology versions 论文

摘要

As ontology development becomes a more ubiquitous and collaborative process, the developers face the problem of maintaining versions of ontologies akin to maintaining ver-sions of software code in large software projects. Versioning systems for software code provide mechanisms for tracking versions, checking out versions for editing, comparing dif-ferent versions, and so on. We can directly reuse many of these mechanisms for ontology versioning. However, version comparison for code is based on comparing text files—an ap-proach that does not work for comparing ontologies. Two ontologies can be identical but have different text representa-tion. We have developed the PROMPTDIFF algorithm, which integrates different heuristic matchers for comparing ontol-ogy versions. We combine these matchers in a fixed-point
