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

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;

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.
