  1. Knowledge Technologies for Description of the Semantics of the Bulgarian Iconographical Artefacts Lilia Pavlova-Draganova Laboratory of Telemаtics – BAS, lilia@cc.bas.bg Desislava Paneva Institute of Mathematics and Informatics – BAS, dessi@cc.bas.bg Lubomil Draganov Institute of Mathematics and Informatics – BAS, lubo@cc.bas.bg

  2. Presentation overview • Why to develop ontology of the Bulgarian iconographical artefacts? • In search of similar ontologies and standards, that could help the ontological representation of the iconographical knowledge • Ontology of the Bulgarian iconographical artefacts • Multimedia digital library “Virtual encyclopedia of Bulgarian iconography” and ideas for implementation of new semantic-based services Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  3. Motivation • Extensionand improvement the functionalities and services in the MDL “Virtual encyclopedia of Bulgarian iconography” • Content- and context-sensitive services for access, browse, search and group of iconographical objects • Presentation the iconographical knowledge in explicit, systematized and clear way • Provision of the basis for future extension of the ontological representation and description of the iconographical knowledge Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  4. Similar ontologies and standards • art-E-fact ontology[Marcos et al. ,’05] • Ontology of art[Thomasson, ’04] • CIDOC оbject-oriented Conceptual Reference Model (CRM) • International Committee for Documentation of the International Council of Museums • ”Object-oriented domain ontology" for expressing the implicit and explicit concepts in the documentation of cultural heritage • Role: enable information exchange and integration between heterogeneous sources of cultural heritage information. • Final version: CIDOC CRM version 4.2 • Official standard: ISO 21127:2006 since 9/12/2006 • Available at: http://cidoc.ics.forth.gr/ Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  5. Class hierarchy in CIDOC CRM Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  6. Ontology of Bulgarian iconographical artefacts Main purpose, scope, and usage Purpose • Presentation of the semantic of Bulgarian iconographical objects, registered in multimedia digital library “Virtual encyclopedia of Bulgarian iconography”, painted by different artists from four iconographic schools, dated from several centuries, and located in Bulgaria. • Provision of a basis for content-sensitive services in the “Virtual encyclopedia of Bulgarian iconography” Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  7. Ontology of Bulgarian iconographical artefacts Main purpose, scope, and usage • Scope: - Restricted number of iconographical artefacts types - icons, plastic iconographical objects, wall-painting, etc. - Fixed historical belonging periods – from XII to XX century - Iconographic schools and their representatives -Tryavna, Bansko, Samokov, Doparsko • Usage:Virtual encyclopedia of Bulgarian iconography (http://mdl.cc.bas.bg/) Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  8. Ontology of Bulgarian iconographical artefacts Conceptualization The knowledge about iconographical artefacts is related to three “thematic entities”: • Identification • General data such as title, type, author, clan, iconographic school, period, dimensions, location, etc. • Description • Scenes and characters, participation in scenes, etc. • Technical • Used techniques, base material, diagnosis or conservation treatment, etc. Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  11. Ontology of Bulgarian iconographical artefacts Juxtaposing with CIDOC CRM Formalization in an ontology language– in a process of consideration Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

  12. “Virtual encyclopedia of Bulgarian iconography” - content Multimedia digital library “Virtual encyclopedia of Bulgarian iconography” Web address: http://mdl.cc.bas.bg/ It includes: • several hundred specimens of the Bulgarian iconography: icons, plastic iconographical objects, wall-painting, etc. from different artists, historical periods, and schools with its detail descriptions. • Techniques of the iconography • Description of significant iconographic schools of The Renaissance • Biographies of known iconographic artists • Glossary Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007
