TLDR
A comprehensive framework for managing various semantic conflicts is proposed that provides a unified view of the underlying representational and reasoning formalism for the semantic mediation process and suggests that correct identification and construction of both schema and ontology-schema mapping knowledge play very important roles in achieving interoperability at both the data and schema levels.Abstract:
Interoperability is the most critical issue facing businesses that need to access information from multiple information systems. Our objective in this research is to develop a comprehensive framework and methodology to facilitate semantic interoperability among distributed and heterogeneous information systems. A comprehensive framework for managing various semantic conflicts is proposed. Our proposed framework provides a unified view of the underlying representational and reasoning formalism for the semantic mediation process. This framework is then used as a basis for automating the detection and resolution of semantic conflicts among heterogeneous information sources. We define several types of semantic mediators to achieve semantic interoperability. A domain-independent ontology is used to capture various semantic conflicts. A mediation-based query processing technique is developed to provide uniform and integrated access to the multiple heterogeneous databases. A usable prototype is implemented as a proof-of-concept for this work. Finally, the usefulness of our approach is evaluated using three cases in different application domains. Various heterogeneous datasets are used during the evaluation phase. The results of the evaluation suggest that correct identification and construction of both schema and ontology-schema mapping knowledge play very important roles in achieving interoperability at both the data and schema levels.read more

Enterprise Architecture Implementation and Management: A Case Study on Interoperability
TL;DR: The case study indicates that interoperability challenges arise because there is no overall coordination of different information systems initiatives in the health sector and because public hospitals have no economic and/or immediate political incentives to share data and business functionality with other organizations.

Review: Interoperability evaluation models: A systematic review
TL;DR: This analysis yields a set of recommendations for any party that is open to the idea of creating or improving an interoperability evaluation model, and performs a comparative analysis among their findings to determine the similarities and differences in their philosophy and implementation.

Information sharing and interoperability: the case of major incident management
TL;DR: It is argued that rather than focusing on interoperability as a primarily technological issue it should be managed as an organisational and informational issue and designed for anomalous situations, which will function during both anomalous and routine situations.

Mediators in the architecture of future information systems
TL;DR: A mediator is a software module that exploits encoded knowledge about certain sets or subsets of data to create information for a higher layer of applications as discussed by the authors, which simplifies, abstracts, reduces, merges, and explains data.
