Resolution of Semantic Heterogeneity in Database Schema Integration Using Formal Ontologies

Farshad Hakimpour, Andreas Geppert
2005 Journal of Special Topics in Information Technology and Management  
This paper addresses the problem of handling semantic heterogeneity during database schema integration. We focus on the semantics of terms used as identifiers in schema definitions.  ...  This paper addresses the problem of handling semantic heterogeneity during database schema integration. We focus on the semantics of terms used as identifiers in schema definitions.  ...  To that end, we rely on formal ontologies available for local schemas. Relating schema elements is performed based on semantic similarity relations.  ...

Searching databases for sematically-related schemas

Gauri Shah, Tanveer Syeda-Mahmood
2004 Proceedings of the 27th annual international conference on Research and development in information retrieval - SIGIR '04  
In this paper, we address the problem of searching schema databases for semantically-related schemas.  ...  We first give a method of finding semantic similarity between pair-wise schemas based on tokenization, part-of-speech tagging, word expansion, and ontology matching.  ...  In this paper, we present an information retrieval technique for finding semantically related schemas in the database.  ...

An Algorithm for Inferring Big Data Objects Correlation Using Word Net

M. Basel Almourad, Mohammed Hussain, Talal Bonny
2016 Procedia Computer Science  
This challenge is traditionally known as schema matching. Due to big data velocity traditional approaches to data matching can no longer be used.  ...  In this paper we present an approach for inferring data objects correlation. We present our algorithm that relies on the objects meta-data and it consults the Word Net thesaurus  ...  In a typical DB integration exercise, a DB schema integrator needs to locate DB schema objects that are relevant to the user information requirement.  ...

Measuring Database Objects Relatedness in Peer-to-Peer Databases

M. Basel Almourad
2013 International Journal of Computer and Communication Engineering  
In this paper we present our approach that measures the similarity of peer schema objects and ultimately depicts database management systems closeness in the overlay.  ...  Identifying relationship between different peer schema objects is one of the main activities so semantically relevant peer database management systems can be acquainted and become close in the overlay.  ...  In a typical DB integration exercise, a DB schema integrator needs to locate DB schema objects that are relevant to the user information requirement.  ...

Query Rewriting with Thesaurus-Based for Handling Semantic Heterogeneity in Database Integration

I Made Riyan Adi Nugroho, I Wayan Budi Sentana
2020 Knowledge Engineering and Data Science  
Funding statement This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.  ...  Semantic diversity at the schema level is related to name conflicts caused by synonyms, hyponyms, hypernym, and polysemy.  ...  In the process of integrating data sources, data can be derived from different places or applications. Hence, its heterogeneously potential in format, structure, syntax, and semantic [2] .  ...

Global Schema Generation Using Formal Ontologies [chapter]

Farshad Hakimpour, Andreas Geppert
2002 Lecture Notes in Computer Science  
Semantic similarity relations between definitions in formal ontologies are defined and used for merging formal ontologies.  ...  We show how similarity relations are discovered by a reasoning system using a higher level ontology. The result of the merging process is used for schema integration.  ...  In order to find out whether elements from different schemas are related, we define similarity relations.  ...

Structural integration: Concepts and case study

J. Geller, Y. Perl, P. Cannata, A. Sheth, E. Neuhold
1993 Journal of Systems Integration  
Currently existing view and schema integration methodologies are based on semantic considerations. They allow integration only if two objects agree in their semantic and structural aspects.  ...  When integrating the views of a large telecommunications application database at Bellcore, it was found that some pairs of view objects had significant structural similarities but differed semantically  ...  The schema in Figure 2 is loosely based on concepts used in the SWITCIT ~ application modeled by Ashok Ingle. Mike Halper has proofread this article.  ...

Matching Schemas for Geographical Information Systems Using Semantic Information [chapter]

Christoph Quix, Lemonia Ragia, Linlin Cai, Tian Gan
2006 Lecture Notes in Computer Science  
Schema matching analyzes and identifies similarities of two schemas, but all approaches can be only semi-automatic as human intervention is required to verify the result of a schema matching algorithm.  ...  However, integrating data from various sources is a tedious task which requires the mapping of the involved schemas as a first step.  ...  Then, an integrated schema is generated and mappings between the integrated schema and the source schemas are established. Other approaches focus on the semantic integration of geographic ontologies.  ...
