Changes of semantics in data sources further complicate the semantic heterogeneity problem. We identify four types of semantic heterogeneities re- lated to changing semantics and present a solution based on an extension to the Context Interchange (COIN) framework. Changing semantics is represented as multi-valued contextual attributes in a shared ontology; however, only a single value is valid over a certain time interval. A mediator, implemented in abduc- tive constraint logic programming, processes the semantics by solving temporal constraints for single-valued time intervals and automatically applying conver- sions to resolve semantic differences over these intervals. We also discuss the scalability of the approach and its applicability to the Semantic Web.
