• Remarks / Further Research

Introduction

• Ontology - a common conceptual basis to specify
  vocabulary used in the Semantic Web
• The Semantic Web
• Ontology Matching
• the process of discovering similarities between
  two ontologies (Predoiu et al, 2006)
• determines the relationships holding two sets of
  entities that belong to two discrete ontologies
  (Shvaiko, 2004)

4
Ontology Matching

• Shvaiko Euzenats classification techniques
  (2005)
• String-based
• Language-based
• Constraint-based
• Linguistic resources
• Alignment reuse
• Upper level formal ontologies
• Graph-based
• Taxonomy-based
• Repository of structures
• Model-based

Literature Survey - Ontology Matching Systems

inherent matching techniques.
7
Findings

• Shvaiko Euzenats Classification Techniques
• String-based
• Language-based
• normally performed prior to string-based
  technique
• no direct engagement in the actual similarity
  computation between two ontologies
• Constraint-based
• Linguistic resources
• Alignment reuse

8
Findings (contd)

• Upper level formal ontologies
• uses external source of common knowledge in the
  form of ontology
• insufficient evidence that specifies the input
  and design guidelines
• Graph-based
• Taxonomy-based
• Repository of structures
• a dynamic approach used to compare fragments of
  two ontologies
• to eliminate the dissimilar portions
• regarded as the follow-up step
• Model-based

3-Tier Classification Framework
10
Remarks

• Existing Ontology Mediation System
• has the improper identification of matching
  techniques
• the lack of an executive approach layer
• a detailed input layer when matching between
  two ontologies
• 3-Tier Classification Framework
• executive approach, basic technique and input
  layers
• provides a clear guideline on designing new
  mediation tool based on the middle view the
  bottom up view

11
Further Research

• Will focuses on implementation based on the
  proposed framework as a means of proof-of-concept
