New Trends in Classification and Data Mining

The observation of the lexical structure of the Bulgarian folklore is very important task for different science domains such as folkloristic, ethnology, linguistics, computational linguistics, Bulgarian language history, etc. Until today, such a linguistic analysis hasn’t been made; it is unclear what is the lexical structure of Bulgarian folklore works. First attempt for computational lexical analysis of the Bulgarian folklore and its constituents is made during the "Knowledge Technologies for Creation of Digital Presentation and Significant Repositories of Folklore Heritage" 1. During the project the Bulgarian folklore digital library (BFDL) is designed and developed. In its structure it is implemented linguistic components, whose aim is the realization of different types of analysis of folk objects from a text media type. Thus, we lay the foundation of the linguistic analysis services in digital libraries aiding the research of kinds, number and frequency of the lexical units that constitute various folk objects. This paper presents basic types of dictionaries needed to carry out such linguistic analysis. It describes the BDFL Linguistics Search in sets of folklore objects of text media type and a linguistic component for frequency analysis of the folklore vocabulary. Finally, a project for implementation of a dictionary concordances of songs, prose, interviews, etc. is outlined.
