Intelligent query processing for semantic mediation of information systems

Saber Benharzallah, Okba Kazar, Guy Caplat
2011 Egyptian Informatics Journal  
The algorithm is self-adapted to the changes of the environment, offers a wide aptitude and solves the various data conflicts in a dynamic way; it also reformulates the query using the schema mediation  ...  Our approach focuses on the exploitation of intelligent agents for query reformulation and the use of a new technology for the semantic representation.  ...  In [25] , the authors propose a multi-agent system to achieve semantic interoperability and to resolve semantic conflicts related to evolutive ontologies domain.  ...

DOGMA-MESS: A Tool for Fact-Oriented Collaborative Ontology Evolution [chapter]

Pieter De Leenheer, Christophe Debruyne
2008 Lecture Notes in Computer Science  
Fact-oriented and layered approaches such as DOGMA have been successful in facilitating domain experts in representing and understanding semantically stable ontologies, while emphasising reusability and  ...  In this paper we extend DOGMA Studio with a set of collaborative ontology evolution support modules.  ...  This allows the DE in finding related conflicts that caused this particular conflict, and how it could be solved. Conflicts can be sorted based on conflict id, type, or cause.  ...

Dealing with Inconsistencies in DL-Lite Ontologies [chapter]

Liping Zhou
2009 Lecture Notes in Computer Science  
The Research Problem As a shared conceptualization of a particular domain, ontologies play an important role for the success of the Semantic Web.  ...  Inconsistency can occur due to several reasons, such as modeling errors, migration or merging ontologies, and ontology evolution. So it is essential to study how to deal with inconsistent ontologies.  ...  By computing preferred models of K with any domain, we find that the conflict sets obtained in any preferred model with respect to different domains are the same and assertions in conflict sets are all  ...

Ontology Evolution: A Survey and Future Challenges [chapter]

Asad Masood Khattak, Khalid Latif, Songyoung Lee, Young-Koo Lee
2009 Communications in Computer and Information Science  
Information semantics and semantic interoperability among applications, systems, and services are mostly based on ontology.  ...  Changes are made to the body of knowledge as experts develop a better understanding of the domain. As a result, the body of knowledge evolves from one state to another.  ...  To make this possible, we need to carefully model the domain knowledge while preserving its semantics [4, 5] .  ...

Steam turbine diagnostic system based on a domain ontology implemented using J2EE technology

Klai Sihem, Khadir M. Tarek, John V. Ringwood
2009 2009 3rd International Conference on Signals, Circuits and Systems (SCS)  
An expert system JESS (Java Expert System Shell) is integrated with the ontology. Knowledge inference is then possible to solve maintenance cases by given adequate diagnoses to given symptoms.  ...  The second aspect of the paper focuses on the possible enhancement and evolution of the developed ontology in order to take into account new maintenance cases.  ...  as well as to solves syntaxes and semantic heterogeneity of integrated systems, improving data exchange between them.  ...

Heterogeneous Data Management on Environmental Sensors Using Ontology Mapping

Kaladevi Ramar, T. T Mirnalinee
2013 Lecture Notes on Information Theory  
In this research syntactic, structural, data and semantic heterogeneities between information systems is considered and a novel ontology mapping technique is developed to resolve semantic heterogeneity  ...  achieving semantic interoperability between ontologies.  ...  Due to an increased awareness of ontology [3] applications and the availability of multiple ontologies over same domain leads to semantic heterogeneities between ontologies.  ...

From the knowledge acquisition bottleneck to the knowledge acquisition overflow: A brief French history of knowledge acquisition

Nathalie Aussenac-Gilles, Fabien Gandon
2013 International Journal of Human-Computer Studies  
As a consequence of the huge amount of available data in the web, a paradigm shift occurred in the domain, from knowledge-intensive problem solving to large-scale data acquisition and management.  ...  In particular, it reports the most significant steps in the parallel evolution of the web and the knowledge acquisition paradigm, which finally converged with the project of a semantic web.  ...  We contrast the evolution of KA with the parallel evolution of the Web and indeed, in the last 10 years, knowledge engineering as a research domain and the Web have converged in particular in the Semantic  ...

Knowledge acquisition environment for the design of a decision support system: application in blood transfusion

S L Achour, M Dojat, C Rieux, P Bierling, E Lepage
1999 Proceedings. AMIA Symposium  
The methodology used could be applied to another highly evolutive medical domain.  ...  Blood transfusion is a medical domain where decision support systems (DSSs) could be very helpful to the physicians but must easily and continuously be maintained.  ...  During domain knowledge acquisition, some conflicts may appear between rules that currently should be solved by the domain expert.  ...

Application of The Semantic Annotation Technology Based on Ontology

Haiming Jing
2015 International Journal of Multimedia and Ubiquitous Engineering  
To resolve the semantic conflicts in the process of data exchange, the ontology is made full use to describe the characteristics of the relation between concept, adding semantics to XML Schema.  ...  In the field of railway, there exist some semantic conflict in the data exchange, by the Ontology OWL fragment extracted from the experiment, semantic conflict will be reduced and even eliminated.  ...  A semantic conflict resolution scheme is proposed, it adopt semantic mapping from relational schema to XML schema and the introduction of ontology mapping file to solve the problems of semantic annotation  ...

A Versioning Management Model for Ontology-Based Data Warehouses [chapter]

Dung Nguyen Xuan, Ladjel Bellatreche, Guy Pierra
2006 Lecture Notes in Computer Science  
More and more integration systems use ontologies to solve the problem of semantic heterogeneities between autonomous databases.  ...  To automate the integration process, a number of these systems suppose the existence of a shared domain ontology a priori referenced by the local ontologies embedded in the various sources.  ...  is solved thanks to the single semantic identification (value of the semantic key) of each instance of data, 2. the problem of the updating process of table schemata is solved through the use of universal  ...

Semantic conflict resolution ontology (SCROL): an ontology for detecting and resolving data and schema-level semantic conflicts

S. Ram, Jinsoo Park
2004 IEEE Transactions on Knowledge and Data Engineering  
We propose a common ontology called Semantic Conflict Resolution Ontology (SCROL) that addresses the inherent difficulties in the conventional approaches, i.e., federated schema and domain ontology approaches  ...  In addition, we present evaluation results to show that SCROL can be successfully used to automate the process of identifying and resolving semantic conflicts.  ...  Jinsoo Park was partially supported by a grant from the SK Fund to the College of Business Administration, Korea University.  ...

Enhancing Service Discovery via Multi-Ontology Management and Annotation

Guang Hui Han, Cheng Zeng
2012 Advanced Engineering Forum  
Ontology, which adds semantic information to services, is an effective tool to automatize service discovery and composition.  ...  However, even in a same domain, different domain experts or users can conceptualize the same real world entities in different views which will lead to multiple domain ontologies.  ...  Therefore, Ontology is usually used to add semantic information to solve this problem [2] .  ...
