Knowledge based integration of heterogeneous databases

Introduction: Cardiac electrophysiology (EP) studies the electrical heart conduction system which is used for diagnosis and treatment of cardiac arrhythmias. In this context, a huge amount of data is generated, requiring efficient and effective access, interpretation, and data analysis from multiple sources in a unified view. To resolve this challenge, this essay presents an ontology to reconcile data heterogeneity problems in this domain.Material and Methods: The cardiac EP ontology was constructed according to the life cycle of ontology building. Structural, functional, and expert evaluation was performed to ensure its quality and usability. Results: Cardiac EP ontology was developed using protégé environment and implemented in OWL editing tool. It presented a detailed hierarchical structure of the cardiac EP domain with around 324 instances describing cardiac EP-related concepts.Conclusion: Cardiac EP ontology provides an explicit formal description of the concepts, relationships, and properties associated with cardiac electrophysiology making seamless data integration between multiple heterogeneous databases. It also is a useful framework for knowledge representation in knowledge-based systems, as well as for explicit communication between experts in the EP domain.

Abstract The process of design depends on the availability of both a variety of data and many different types of knowledge drawn from specialists. Most of the data is naturally stored in various databases while the knowledge can often be organised in Knowledge-based Systems (KBSs). A design support system is thus required to comprise a number of elements such as databases and knowledge-based systems, as well as conventional analytical modelling systems. In common with many software environments that have been developed over several years these elements tend to form autonomous islands based on perhaps different computers or data servers between which exchange of data is difficult. Even in the more recent expert system field, communication is limited between different advisory programs, or between such programs and the databases which they use for inference. One central issue in designing such a support system is to identify means by which multiple systems can co-operate in an inter-connected environment and share data which is distributed over heterogeneous databases. This paper describes an Interprocess Communication (IPC) based integration framework which is designed to facilitate dynamic and smooth data communication between the cooperating KBSs and databases within a design support system.

Abstract. Research demonstrates that the negative relationship between Openness to Experience and conservatism is heightened among the informed. We extend this literature using national survey data (Study 1; N = 13,203) and data from students (Study 2; N = 311). As predicted, education – a correlate of political sophistication – strengthened the negative relationship between Openness and conservatism (Study 1). Study 2 employed a knowledge-based measure of political sophistication to show that the Openness × Political Sophistication interaction was restricted to the Openness aspect of Openness. These studies demonstrate that knowledge helps people align their ideology with their personality, but that the Openness × Political Sophistication interaction is specific to one aspect of Openness – nuances that are overlooked in the literature.
