POAF: Portable ontology aligned fragments

Abstract

In today's semantic web, ontology fragmentation and modularization are considered as important tasks due to the size and complexity of prime ontologies. At the same time, the ontology alignment community thrives with solutions for discovering and producing alignments between semantically related concepts. However, these are seldom used in bulk and their subsequent re-use is somewhat problematic. In this paper we set to explore these issues from a practical viewpoint: use ontology alignments to inform an ontology fragmentation strategy for the benefit of exposing and distributing rich ontology aligned fragments.
