2009 Lecture Notes in Computer Science  
based on the identified mappings.  ...  In this dissertation, we propose a schema integration framework which (1) is only concerned with semantic mappings (that associate schema objects based on simple set based comparisons of the objects' instances  ...  Based on these mappings schema merging of S er 1 and S er 2 could be performed.  ...

A framework for semantic grouping in P2P databases

Verena Kantere, Dimitrios Tsoumakos, Timos Sellis
2008 Information Systems  
A set of mappings between S, S ′ is denoted as Semantics are 'flooding' from one peer to the other, through respective mappings: Definition 3.  ...  Extended discussion and details on acquaintance mappings, query rewriting, query similarity etc can be found in [25] .  ...  Finally, we require that the merging procedure is based only on available information on the peers, i.e. it exploits solely the peer schemas and the peer mappings.  ...

Automatic generation of mediated schemas through reasoning over data dependencies

Xiang Li, Christoph Quix, David Kensche, Sandra Geisler, Lisong Guo
2011 2011 IEEE 27th International Conference on Data Engineering  
Classical data integration systems rely on a mediated schema created by human experts through an intensive design process. Automatic generation of mediated schemas is still a goal to be achieved.  ...  We generate mediated schemas by merging multiple source schemas interrelated by tuple-generating dependencies (tgds).  ...  ACKNOWLEDGMENT The work is supported by the Research Cluster on Ultra High-Speed Mobile Information and Communcation UMIC (http://www.umic.rwth-aachen.de).  ...

2009 International journal of computer integrated manufacturing (Print)  
This paper presents a semantic-mediation architecture that enables standards-based interoperability between heterogeneous supply-chain applications.  ...  The design-time tools supported a domain ontology definition, message annotations, message schema transformations, and reconciliation rules specifications.  ...  Further distinction is based on the reconciliation approach applied -merging or mapping.  ...

Global Schema Generation Using Formal Ontologies [chapter]

Farshad Hakimpour, Andreas Geppert
2002 Lecture Notes in Computer Science  
Instead, we present an approach based on formal ontologies presented in a logical language for integrating schemas to produce global schemas.  ...  We focus on the part of semantics related to the meanings of terms used to name schema elements. Our approach does not rely on the names of the schema elements or the structure of the schema.  ...  similarity and creation of class hierarchy based on merged ontology.  ...

based on the identified mappings.  ...  The core problems in schema integration are: schema matching, i.e. the identification of correspondences, or mappings, between schema objects, and schema merging, i.e. the creation of a unified schema  ...  Schema Merging In [8] , we have defined the merging of schemas based on the semantic mappings specified between their schema objects.  ...

Combining RDF and XML schemas to enhance interoperability between metadata application profiles

Jane Hunter, Carl Lagoze
2001 Proceedings of the tenth international conference on World Wide Web - WWW '01  
Finally using examples and mapping implementations based on XSLT and a metadata ontology, we demonstrate how interoperability between application profiles can be enhanced by using a dual schema approach  ...  So far approaches to application profiles have been based on either RDF Schemas [5] or XML Schemas [6, 7, 8] . The SCHEMAS project [9] has adopted a purely RDF Schema approach.  ...  Combined with the semantic knowledge provided by MetaNet, XSLT is capable of performing both the semantic mapping and the structural and syntactic mapping required between metadata descriptions based on  ...

A layered approach to semantic similarity analysis of XML schemas

Jaewook Kim, Yun Peng, Serm Kulvatunyou, Nenad Ivezic, Albert Jones
2008 2008 IEEE International Conference on Information Reuse and Integration  
Past research on schema mapping has not fully utilized semantic information in the XML schemas.  ...  In this paper, we propose a semantic similarity analysis approach to facilitate XML schema mapping, merging and reuse.  ...  Our approach focuses on recommending a set of data elements in the target schema as likely mapping/merging candidates for each element in the source schema based on their semantic similarities.  ...
