- 9. Requirements • Cost-efficient Ontology Construction • Cost-efficient Annotation • Speed • User Interface Martin Hepp 7 mhepp@computer.org
- 10. Competency Question Martin Hepp 8 mhepp@computer.org
- 11. Overview: OntoNaviERP Martin Hepp 9 mhepp@computer.org
- 12. Which Terms Are Most Valuable - The Most Popular, the Frequent, or the Rare? Frequency vs. Information Value vs. Likelihood of Relevance Web-wide Number of Occurrences + Likelihood of relevant documents + Likelihood of usage in queries - limited information value balance between frequency and specificity + higher information value + highest information value if needed - likelihood of occurrence in query low - likelihood of relevant documents low Term 1..N (similar pattern for: Tags, Ontology Elements) Martin Hepp 10 mhepp@computer.org
- 13. Approach: Conceptual Model Martin Hepp 11 mhepp@computer.org
- 14. Approach: Conceptual Model Semi-automatically Traditional derived from ontology term lists engineering Martin Hepp 11 mhepp@computer.org
- 15. Approach: Ontology Construction (1) • Script • Protégé • WordNet Plug-In • OWL Annotation Property • .NT Generator Martin Hepp 12 mhepp@computer.org

- 21. Evaluation Methodology Martin Hepp 18 mhepp@computer.org
- 22. Results (1) Median of retrieved documents • Term-based: 0 >=50% of the action-topic pairs yield no result • OntoNaviERP: 5.5 50% of of the action-topic pairs return at least 5 result pages, of which 2 are relevant Martin Hepp 19 mhepp@computer.org
- 23. Results (2) Martin Hepp 20 mhepp@computer.org
- 24. Findings and Lessons Learned • Understanding of ontology engineering and annotation under economic constraints • In our setting, consolidation of synonyms and lexical variants does a great deal of the job Martin Hepp 21 mhepp@computer.org
- 25. Future Extensions • Task and Context • Annotate individual sections of resources • Skills / Users’ Competencies vs. Target Audience of a Resource • Hybrid Search: Combining term-based and conceptual search E.g. see Bhagdev/Chapman/Ciravegna, Vitaveska Lanfranchi, Daniela Petrelli: Hybrid Search: Effectively Combining Keywords and Semantic Searches, ESWC 2008 Martin Hepp 22 mhepp@computer.org
