1 A Tool to Support Ontology Creation Based on Incremental Mini- Ontology Merging Zonghui Lian Data Extraction Research Group Supported by Spring Conference 2007

2 2 The Problem: Ontology Creation Information collection and analysis Concept and relationship design Iterative construction

3 3 TANGO : Table ANalysis for Generating Ontologies Mini-ontology Growing ontology Merged growing ontology

4 4 Workflow Manual

5 5 Workflow Manual Automatic

6 6 Workflow Manual Automatic Semi-automatic

7 7 Features Graphical mapping and merging Manual and semi-automatic modes APIs supporting mapping and merging algorithms  Ontology components  Instance values  Mapping information  Issue-Default-Suggestion (IDS) statements for user interaction

8 8 Ontology Mapping and Merging: Example 1

9 9 Ontology Mapping and Merging: Example 2

10 10 Ontology Mapping and Merging: Example 2

11 11 Ontology Mapping and Merging: Example 2

12 12 Ontology Mapping and Merging: Example 2

13 13 Ontology Mapping and Merging: Example 2

14 14 Validation Test the usability of the tool:  Efficiency  Accuracy Test whether the tool is extensible w.r.t. different mapping and merging algorithms

15 15 Contribution A tool to support ontology mapping and merging  Manual  Semi-automatic (via plug-in algorithms) TANGO: ontology creation
