  • Automatic Discovery of Semantic Relationships between Schema Elements  
  • by Nikos Rizopoulos — 2004 — In Proc. of 6th ICEIS
  • …Abstract: The identification of semantic relationships between schema elements, or schema matching, is the initial step in the integration of data sources. Existing approaches in automatic schema matching have mainly been concerned with discovering equivalence relationships between elements. In this…

  • AutoMed Model Management  
  • by Andrew Smith, Nikos Rizopoulos, Peter Mcbrien
  • …Abstract. Model Management (MM) is a way of raising the level of abstraction in metadata intensive application areas. The key idea behind Model Management is to develop a set of generic algorithmic operators that work on schemas and mappings between schemas, rather than individual schema elements. I…

  • Uncertainty in Semantic Schema Integration  
  • by Nikos Rizopoulos, Matteo Magnani, Peter M C Brien, Danilo Montesi
  • …In this paper we present a new method of semantic schema integration, based on uncertain semantic mappings. The purpose of semantic schema integration is to produce a unified representation of multiple data sources. First, schema matching [1] is performed to identify the semantic mappings between th…

  • Schema integration based on uncertain semantic mappings  
  • by Matteo Magnani, Nikos Rizopoulos, Peter M C Brien, Danilo Montesi — 2005 — In International conference of conceptual modeling
  • …Abstract. Schema integration is the activity of providing a unified representation of multiple data sources. 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 unifi…

  • AutoMed: A BAV data integration system for heterogeneous data sources  
  • by Michael Boyd, Sasivimol Kittivoravitkul, Charalambos Lazanitis, Peter M C Brien, Nikos Rizopoulos — 2004 — In Proc. CAiSE'04
  • …Abstract. This paper describes the AutoMed repository and some associated tools, which provide the first implementation of the both as view (BAV) approach to data integration. Apart from being a highly expressive data integration approach, BAV in additional provides a method to support a wide range …
