2 Outline Vision: National Semantic Web Infrastructure FinnONTO Ontology Infrastructure Ontologies Ontology Library Services

3 Vision: National Semantic Web Infrastructure

4 Lessons Learned from MuseumFinland Finnish Museums on the Semantic Web First system integrating museum collections form different museums based on semantic web ontologies and RDF Online since 2004: [Hyvönen, et al., Journal of Web Semantics, 2005] W3C domain independent ontology standard RDF(S) is useful but Domain specific standards i.e. actual ontologies are missing There were no ontologies in Finnish reflecting Finnish cultural heritage There were useful thesauri around, such as General Finnish Thesaurus (YSA) Thesaurus for Museum Domain (MASA) Let s create and share together ontologies on a national level! With interoperability to international ontologies => National Finnish Ontology Project FinnONTO ( )

5 FinnONTO Thesis Semantic Web needs a content infrastructure for interoperability Especially useful in Cross-domain applications Collaborative Web 2.0 applications

6 Traditional Infras: (rail)roads, electricity, Semantic Content Infra: Ontologies, data, metadata

7 Intellectuals solve problems - geniuses prevent them Albert Einstein

9 FinnONTO Ontology Infrastructure

10 FinnONTO Approach: Preventing Problems in Advance by Collaboration Sharing Ontologies Creating a Library Service of Mutually Interoperable Vocabularies/Ontologies Sharing Metadata Schemas Sharing Linked Open Data [Hyvönen et al., ICSC 2007, ESWC 2009, SW Journal 2010]

11 Major Components of FinnONTO Ontology Infrastructure Ontologies Ontology Library Services

12 Ontologies

13 Major Domain Ontology Types Needed General Concept Ontologies Actor Ontologies Place Ontologies Time Ontologies Event Ontologies Domain Nomenclatures and Terminologies Domain ontology refers thesaurus or gazetteer like KOSs whose resources are used is element values of metadata descriptions

14 General Concept Ontologies

15 A Method for Transforming Keyword Thesauri into Light Weight Ontologies Input: a thesaurus using standard ISO [2788] / SFS 5471 Semantic relations: NT, BT, RT, USE, USED FOR,... Used widely in Finland Fairly large vocabularies, e.g., YSA 24,000 terms Output: a light-weight subclass-of ontology Complete subclass-of hierarchy Hierarchical relationships Based on NT / BT relations of the thesaurus Transitive subclass hierarchy sceletons Part-of and associative relations distinquished from subclass-of Disambiguation of meanings Semantic disambiquation of term meanings Preferred vs. non-preferred terms (USE / USED FOR) Multilinguality

16 Example of Transitivity Issues make-up mirrors BT mirrors mirrors BT furniture make-up mirrors subclassof furniture When searching furniture make-up mirros would be in the result!

17 Example: University Terminology YSA Thesaurus -> YSO Ontology Thesaurus Ontology

18 KOKO: Linked Ontology Cloud / Network Each ontology was aligned with the top ontology YSO by machine and then corrected by hand [Hyvönen et al., ESWC, 2008] Protege editor (Stanford University) was used for editing Skosify tool was developed for validating and transforming ontologies into SKOS [Suominen, Hyvönen, EKAW, 2012] Some additional tools were developed, such as MUTU for managing changes in the top ontology [Pessala et al., ISWC WS, 2011] and KOAN for inspecting overlapping areas

22 Ontology Developers in Action Work goes now on at the National Library based on the FinnONTO prototype Validating and correcting ontologies (e.g. translations) Finalizing the parts and structure of the ontology cloud Minimizing overlapping areas

23 Actor Ontologies

24 Resolving and Aligning Identities - Linguistic variations - Pseudonames (Mark Twain = Samuel Clemens), nicknames - Honorary names (e.g., popes, kings,...) - Name changes (e.g., due to marriage) in time - Different names used in different communities

25 ONKI People Ontology Service A demo with Getty ULAN 120,000 Instances Faceted Search [Kurki, Hyvönen, ICSD, 2010]

26 Use Case: CultureSampo How is A. Gallen-Kallela related to Napolean I? [Mäkelä et al., Semantic Web Journal, 2012]

27 Use Case: Semantic National Biography biographies of the National Biography (Finnish Literature Society) CIDOC CRM data ( events) linked with 4 additional datasets to enrich data based on (SKS) aineistoon perustuen [Hyvönen et al., ISWC P&D, 2014]

28 Place Ontologies

29 ONKI Geo for Geo-ontologies 800,000 contempory Finnish places Finnish historical places Millions of places abroad (GNS,GNIS)

30 Historical Place Ontology of Finland (counties, municipalities) Modeling Changes of Regions [Kauppinen et al., 2007, Hyvönen et al., 2011]

31 Time Ontologies

32 Modeling linear and cyclic time Time periods are different in different countries E.g. Bronze Age in Egypt and Nordic Countries Modeling uncertainty in time [Kauppinen et al., IJHCS, 2010]

33 Event Ontologies

34 Using Events as References (URI) Example: Bettman Archive Foto [Doerr, 2004] Dublin Core record related to the Yalta Conference Matadata does not refer explicitly to the Yalta Conference or WW II Based on shared events, content could be aggregated Searching stuff dealing with the events Finding semantic associations based on events and their clusters
