XMeta Repository and Services [chapter]

Lee Scheffler
2006 Lecture Notes in Computer Science  
Objects, being the data of models, could be stored in relational databases, and ontologies appear as a good candidate for capturing the semantics of models.  ...  Starting from the design of OO models for applications, developers also expect to address issues on the data of models and the semantics of models.  ...  Admittedly, tools like the D2R server [2] are available for publishing relational databases on the Semantic Web, which means a solution to bridge the relational data and ontologies.  ...

Resolving semantic heterogeneity through the explicit representation of data model semantics

Susan D. Urban, Jian Wu
1991 SIGMOD record  
The ffi~t statement in Figure 2 indicates the start of specifications for mappings from the semantic model to the relational database DB1.  ...  In addition to using the semantic model for representing its own structural semantics, the model is also used to describe the semantics of the data models employed by the local schemas that map to the  ...

Integrating a modern knowledge-based system architecture with a legacy VA database: the ATHENA and EON projects at Stanford

A Advani, S Tu, M O'Connor, R Coleman, M K Goldstein, M Musen
1999 Proceedings. AMIA Symposium  
We found that to achieve our design goals, the mediator requires two separate mapping levels and must itself involve a knowledge-based component.  ...  We describe a new database mediator that affords the EON system both physical and logical data independence from the legacy VA database.  ...  These mappings have their own proprietary semantic assumptions about the most appropriate mapping from the VA database to a relational model.  ...

A New Approach for Semantic Integrity Constraints Representation in Enhanced Entity-Relationship and Relational Database Schemas

Islam Hassan AlTarawneh
2016 International Journal of Database Theory and Application  
The proposed SEER and SRD models embed the semantic constraints using a new notations and pseudo code to give a full diagram for a database system.  ...  In this paper Semantic-Enhanced Entity Relationship (SEER) and Semantic -Relational Database (SRD) diagrams are proposed.  ...  This model represents the database as a set of relations. E.F.Codd in [6] introduced an extensions in relational model to support atomic semantic.  ...

Discovering new technique for mapping relational database based on semantic web technology [article]

Noreddine Gherabi, Khaoula Addakiri, Mohamed Bahaj
2021 arXiv   pre-print
how relational databases can be used to define a mapping mechanism between relational database and OWL ontology.  ...  In this paper, we present an new approach to map the data stored in relational databases into the Semantic Web, we exploit simple mappings based on some specifications of the database schema, and we explain  ...  g denotes primary key of the Semantic enrichment model (SEMO) in semantic Web is a process of analyzing and examining a database to capture its structure and definitions at a higher level of meaning.  ...

Application of The Semantic Annotation Technology Based on Ontology

Haiming Jing
2015 International Journal of Multimedia and Ubiquitous Engineering  
In this paper, the semantic conflict resolution model is introduced, the indirect method is applied and the ER model is applied to realize the semantic mapping from relational schema to XML Schema, this  ...  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.  ...  Although the database reverse engineering can extract the semantic structure relation model from a relational database, but more complicated implicit mode is very difficult to obtain, so the extracted  ...

Towards a standard query model for sharing decision-support applications

W Sujansky, R Altman
1994 Proceedings. Symposium on Computer Applications in Medical Care  
We present the components of this framework, discuss their desirable features, and describe a prototype that we have developed for relational patient databases.  ...  When such applications include queries to electronic patient databases, the queries must be translated to conform to local database specifications.  ...  Das has defined a formal temporal semantics for relational clinical databases and a set of relational operators to resolve temporal heterogeneities among legacy databases [20] .  ...

Cohabitation of Relational Databases and Domain Ontologies in the Semantic Web Context

Leila Zemmouchi-Ghomari
2018 Journal of Systems Integration  
This paper aims to bridge the gap between ontologies and databases in the context of the Semantic Web by highlighting their advantages and disadvantages, their complementarity, and the most popular means  ...  On the other hand, ontology technology is the most promising solution for concretizing the Semantic Web vision; however, it has not been recognized as the Semantic Web data model thus far.  ...  Consequently, the closed-world assumption is applied to the relational database model, which represents a major semantic loss in the process of modeling information.  ...

A Knowledge-Based Approach to Querying Heterogeneous Databases [chapter]

M. Andrea Rodríguez, Marcela Varas
2002 Lecture Notes in Computer Science  
This paper presents a new approach to querying heterogeneous databases that maps the semantics of query objects onto database schemas.  ...  These similar classes are then mapped onto a database schema, which is compared with schemas of heterogeneous databases to obtain entities in the databases that answer the query.  ...  We also want to thanks to Max Egenhofer's contribution to the previous work upon which this paper is based, and to Jim Farrugia for his valuable comments.  ...

Secondly, to extend the abstract ontology model according to the databases. The method facilitates to apply similarly SPQRAL queries to search the data in the databases.  ...  The ontology modeling is divided into two phases, initially to translate the database rules according to ontology rules to find an abstract ontology model.  ...  A Global schema-based mapping approach is presented in [31] where a set of mapping rules are defined to extract a global ontology model from the database.  ...

A framework for OWL DL based Ontology Construction from Relational Database using Mapping and Semantic Rules

C. Ramathilagam, M. L. Valarmathi
2013 International Journal of Computer Applications  
One alternate to compensate for the rich set of data is to take the contents of Relational Data Base (RDB) for domain related applications in the Semantic Web.  ...  This paper proposes an RDB to Ontology mapping system framework which can generate an Ontology based on the proposed Mapping Rules for a Banking domain.  ...  The most popular example of a database model is the Relational model, which uses a table-based format.  ...
