Interoperability and Semantic Technologies 2015-16

by unknown authors , 2015
"... The course is organised in three parts. In the first part, it starts arguing about the difference between pair-wise system integration and multi-later system interoperability. It introduces the four levels at which the interoperability problem has to be attacked (i.e., legal, organisational, semanti ..."

language to model heterogenous data sources in an open world where information cannot be assumed to be complete. It illustrates SPARQL [6]- a query language for RDF. It shows how to put all the pieces together in order to achieve interoperability among heterogenous information systems using principles from

Impact of semantic heterogeneity on federating databases

by Robert M. Colomb - The Computer Journal , 1997
"... The dif"cult problems in the design of systems which facilitate interoperation and mediation among information sources and their consumers arise from the presence of semantic heterogeneity among the schemas and ontologies supporting the different services. The purpose of this paper is to de ..."

SchemaSQL -- A Language for Interoperability in Relational Multi-database Systems

by Laks Lakshmanan, Fereidoon Sadri, Iyer N. Subramanian , 1996
"... We provide a principled extension of SQL, called SchemaSQL , that offers the capability of uniform manipulation of data and meta-data in relational multi-database systems. We develop a precise syntax and semantics of SchemaSQL in a manner that extends traditional SQL syntax and semantics, and demon ..."

Achieving Semantic Interoperability in Heterogeneous Information Systems with Topic Maps

by Giovani Rubert Librelotto, José Carlos Ramalho, Pedro Rangel Henriques
"... Abstract. Nowadays, data handled by an institution or company is spread out by more than one database and lots of documents of different types. To extract the information implicit in that data, it is necessary to pick parts from those various archives. To obtain a general overview, those information ..."

Privacy-preserving Semantic Interoperation of Heterogeneous Databases

by Peng Liu, Prasenjit Mitra, Chi-chun Pan
"... Two major challenges to enabling secure interoperation among web-information sources are resolving semantic heterogeneity across websites and maintaining the privacy of the data and metadata of organizations owning the websites. In this paper, we propose SACE, a novel, implemented middleware toolkit ..."

ON RESOLVING THE PROBLEM OF SEMANTIC HETEROGENEITY IN CLINICAL INFORMATION SYSTEMS

by Ching-song D. Wei, Simon J. Doong, Sam Y. Sung, Peter A. Ng
"... The input and output data of a Clinical Information System (CIS) depend heavily on the use of a medical database and an intensive Graphic User Interface (GUI). Currently there are a number of healthcare information standards, such as HL7 (Health Level 7, 2006) and Medical Markup Language (Medical Ma ..."
Abstract - Add to MetaCart
-known problems of data heterogeneity with the distributed database systems have to be solved. In this paper, we begin to describe the structured and unstructured text data in a Clinical Information System (CIS), and then focus on the problem of semantic heterogeneity. We exploit the ontology to represent

Managing Heterogeneity in Inter-Operating Medical Information Systems

by Maurice Dixon, Jana Kohoutková, Stephen Cook, Keith Jeffery, Brian Read , 1996
"... This paper reports the progress made in managing the heterogeneities that arise in interoperating medical information systems. The approach taken is to define a domain ontology through the use of a reference model which allows for system evolution. Use is made of a five layer information expressivit ..."

Context Modeling and Transformation for Semantic Interoperability

by Heiner Stuckenschmidt, Holger Wache - In Knowledge Representation Meets Databases (KRDB , 2000
"... Mediators are middleware components that provide a exible integration of several heterogeneous information systems. But current approaches ignore that each information has to be considered in its context. Besides the integration the information has to be also converted from its source context int ..."

Interoperability in Open Heterogeneous Multirobot Systems

by S. Ambroszkiewicz, W. Bartyna, M. Faderewski, G. Terlikowski, K. Cetnarowicz
"... An approach to the problem of interoperability in open and heterogeneous multirobot systems is presented. It is based on the paradigm of Service Oriented Architecture (SOA), and a generic representation of the environment. Robot, and gener-ally device, is seen as a collection of its capabilities exp ..."

"... The goM of the InfoSleuth project at MCC is to exploit and synthesize new technologies into a unified system that retrieves and processes information in an ever-changing net- work of information sources. InfoSleuth has its roots in the Carnot project at MCC, which specialized in integrating heteroge ..."

However, recent emerging technologies such as internetworking and the World Wide Web have significantly expanded the types, availability, and volume of data available to an information management system. Furthermore, in these new environments, there is no formal control over
