2. 2 Topic maps variant forms of names 3 topic maps based projects Topic maps cultural heritage Topic maps archives

3. 3 Use users’ research to determine the variant forms Minimum rate to become a variant form The variant form will be included in topic definition Possibility to browse the right and wrong forms Variant forms of names

4. 4 Variant forms of names: calculate minimum rate Minimum Rate Parameters 2 > K < 3 to refine search Questionnaire Number Empirical formula to define mininum rate: the main idea is to found an equation that decrease lowly when the number of questionnaire increases. For i.e. if with 100 questionnaire we need 15-16% as minimum rate to become variant form, with 10000 2,5% (250 searches) could be enough.

6. 6 Example Shakespeare (I) Minimum rate: 8% Results: Shakespeare 82% Shakespear 13% Others forms 5% include it in the topic definition or just link to the correct form

7. 7 Shakespeare Shakespear Apocope Example Shakespeare (II)

8. 8 Example Shakespeare (III)

9. 9 Example Shakespeare (IV) Shakespeare Shakespear We could use also a reification

10. 10 Example Shakespeare (V)

13. 13 TM & Variant forms: conclusion Features: Use users’ researches to define variant forms of names Manage variant forms with topic maps Enable browsing the correct and the wrong forms Incorporate in existing software

14. 14 Managing related terms in a cultural system Interoperability: A standard to include other standards Problem: standards do not satisfy the requirements of all parties Solution: specific standards at a lower level with relations expressed in a topic map at a higher level – topic maps as a tool for harmonization

15. 15 Topic maps as a harmonizing instrument The entity level recognize different forms, that would be described differently under one single ontology The structure level manage different models The semantic level Taxonomies, access point

16. 16 Entity level Example: Manage as a single ontology Liliana Grassi as creator Liliana Grassi as author With a description for each different aspect occurencesscopes
