Ontology integration can be used to solve heterogeneity of different information. Different to the usual global interpretation, distributed interpretation based on DDL is taken to interpret its semantics. As a result, traditional coherence checking algorithm is not suitable any more. In this paper, we propose an algorithm to measure coherence of ontology integration under distributed interpretation. In our proposal, ontology integration is taken as global ontology and local ontologies connected by ontology mapping. Consistency and coherence are viewed as different things. Then a two-phrases checking algorithm is designed to test coherence of ontology integration. Some experiments are made to test its feasibility. We compare checking results with other algorithms, especially with that under global interpretation. Our algorithm can improve efficiency to some degree, but it is subjected to mapping relations which are found by mapping tools.
