Linguistics research and analysis of the Bulgarian folklore (1)

The main component of the linguistic research of the Bulgarian

folklore is the analysis of its lexical structure.

• How many and what token it contains?

• Is there and what is the domination or the lack of some groups

of tokens?

• Paradigm relationships in the folklore lexemes

• Context lexemes/Folklore language formulas

• Frequency of the lexemes, verses/sentences in which they

are, number, numbering in the song, etc. of the

verses/sentences.

• Word forms

• Regional characteristics of the folklore lexical structure, etc.

Linguistics research and analysis of the Bulgarian folklore (2)

Tools, formalizing the folklore analysis:

• Frequency dictionary

• A general frequency dictionary – it contains the all lexical

units which are in a folklore object repository;

• A regional frequency dictionary – it contains all the text units

which come of a definite folklore region or of a concrete

settlement;

• A functional frequency dictionary – it contains all the text

units which have identical functions: descriptions of the

rites, various types of songs, narratives, etc.

Linguistics research and analysis of the Bulgarian folklore (4)

• Concordance dictionaries show the lexeme with/in her

context.

• Example for songs: “Fifty heroes are drinking wine” – the

underlined lexeme is the examined and the lexemes in

italic are her context.

• Example for narrative text: In the description of the rituals

one complete sentence is the context of the observed

lexeme (from point to point).

FolkKnow project

• FolkKnow project: “Knowledge Technologies for Creation of

Digital Presentation and Significant Repositories of Folklore

Heritage” (contract number: IO-03-03/2006)

• Supported by National Science Fund of the Bulgarian Ministry of

Education and Science

• Partners: Institute of Mathematics and Informatics - BAS,

Institute for Folklore-BAS, Veliko Tarnovo University

• Module 3: “Development of Digital Libraries and Information Portal

with Virtual Exposition - Bulgarian Folklore Heritage”

• Module for

– Managing and monitoring users’ data and activities:

registration, logs, data changes, level set, actions,

related to the object manipulation: search, preview ,

delete, add, edit, select, etc., administrative actions.

– File format conversion

– XML export of the BFDL objects

Linguistic search in text folklore objects

• Search of a word in the different types of dictionaries;

• Search of two or more words, searching of verbal formulas in the folklore lexis: “Drinking wine”, “Marko seated”.

• Search of a group of words, investigating the paradigmatic relations in the folklore lexis (river- stream- brook- rill…)

• Search for a root of a word, studying the folklore word-formation: “drink” (I am drinking, I have drunk, they have drunk…).

Experimental implementation of a linguistic component in

BFDL

Frequency dictionary functional specification• Linguistic analysis of the available set of test

folklore objects;• Determination of the frequency of meeting the

lexemes in text folklore objects;• Creating of lists of the lexemes,

– in frequency order– in alphabetical order

• Taking the number of the lexical units;• Taking the number of the repeats of the lexical

units.
