Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

“Knowledge Technologies for Creation of Digital Presentation and Significant

Repositories of Folklore Heritage” (FolkKnow) project

- Aims and tasks; - Target domain; - Target group of users; - Technologies that will be used;

Bulgarian folklore ontology – the first stage of project work

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Ontological Presentation of Folklore Knowledge

- Ontology (according Grubber);

- Use of ontologies

- data-interchange;

- data-integration;

- data-querying;

- data visualization, etc.

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Bulgarian Folklore Ontology

- Main purpose and scope of the ontology; data collection;

- Conceptualization;

Problems and discussions:- Segmentation of the folklore text;- The records of Bulgarian folklore are

partial and they do not display the whole information;

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Bulgarian Folklore Ontology

- Current folklore descriptions schemes don’t define clearly and unanimously their subject areas;

- Transformation of the enormous objects` number into an end number of ontological units;

- Opportunity for minimalization of the contextual defect;

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Bulgarian Folklore Ontology

Defined thematic entities:

- Identification and description;- Technical;

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Bulgarian Folklore Ontology

- Definition of the concepts and properties;

- The Bulgarian folklore ontology is composed of more than 650 concepts and properties;

Semantics of the Complex Folklore Objects

- Simple Folklore Objects: “song”, “food”, “magic”, etc.

- Complex Folklore Objects - archived objects which cannot be so clearly and simply (synonymously) classified: the same unit (material), according to its informational content, could be classified into different Folklore Object Types

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Semantics of the Complex Folklore Objects

- CFO A1_146_2-14 - an interview containing information of the catholic community in the village of Oresh, Svishtov region, northern Bulgaria. The emphasis in the interview is on the ritual, festival, and everyday life in the village, on the popular beliefs and knowledge.

Bulgarian Folklore Ontology

Formalization:

- Web Ontology Language (OWL);

- OWL Protégé;

National investigations and projects for virtual presentation of ethnographic and

folklore artefacts- “Bulgarian Ethnographic Treasury” (

http://mdl.cc.bas.bg/ethnography/);- “Yuper” (http://yuper.hit.bg/);- “Folklore Motives and Anthologies” (http://liternet.bg/);- “WebFolk Bulgaria” (http://musicart.imbm.bas.bg/EN/Default.htm);- “Living Human Treasures” (

http://www.treasures.eubcc.bg/main.php)- “Virtual Encyclopaedia of Bulgarian Iconography” (

http://mdl.cc.bas.bg/), etc.

- Digital Library of Bulgarian Folklore – will be a valuable gallery of artefacts and knowledge for traditional Bulgarian culture, art and folklore;

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Implementation

Opportunities that ontology will provide to the digital library of Bulgarian folklore:

- advanced approaches for folklore content representation, browsing and access;

- synchronous, diachronic and asynchronous point of view and analysis;

- etc.

Final HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007

Conclusion

- Bulgarian folklore heritage will be semantically described and presented virtually;

- Addressed to a wide range of potential users;

- We popularize the idea of integration the traditional Bulgarian culture and folklore in the European virtual culture space;
