Dictionaries classifications: By format: traditional dictionaries, digital dictionaries (online (web-based) or local (desktop)) By their purpose: descriptive dictionaries, grammar dictionaries, dictionary of synonyms, valence dictionary, dictionaries of etymology, phrase logical dictionaries, frequency dictionaries, concordance dictionaries, specialized dictionaries, terminological dictionaries, etc. By the number and type of languages: mono-lingual, bilingual, multi-language dictionaries

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. W ord forms R egional characteristics of the folk lore lexical structure, etc.

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.

Table: Comparison of the Bulgarian folklore and spoken language s

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).

Description of folklore object

Extended search through all the object’s characteristics

 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…).

Frequency dictionary functional requirements  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.

 frequency dictionary for texts with folklore themes  WEB interface  full text search  rules and concepts in the field of Bulgarian folklore that filter the words/phrases  words/phrases are representatives of 20 different folklore rubrics (thematic headings)

 administrative area:  Adding of a text: here the application has a text field, that enables addition of text and a field that enables upload of the source file.  Adding of a rubric: the application is simplified to the limit and the administrator chooses the level on which he wants to add a rubric and gives only its name  Change of a rubric  Deletion: After an object is chosen to be deleted at the chosen level, the system deletes cascade all lower levels  User part:  composed of the search form that allows for selecting a desired item, the level and the corresponding text. The results appeared on the screen in which information rubric, how many files and how the words are distributed

 Full text search:  System perform a full text search of corpuses of text  Text filtration by rubrics, indexes or metadata
