Bulgarian is one of the many languages whose text corpora are included in Sketch Engine, a tool for discovering how language works. Sketch Engine is designed for linguists, lexicologists, lexicographers, researchers, translators, terminologists, teachers and students working with Bulgarian to easily discover what is typical and frequent in the language and to notice phenomena which would go unnoticed without a large sample of Bulgarian text.

Sketch Engine has tools to identify and analyse collocations, synonyms and antonyms, examples of use in context, keywords or terms. Frequency word lists of Bulgarian single-word or multi-word expressions of various types can be generated. Even users without any technical knowledge can create their own Bulgarian corpus using the Sketch Engine’s intuitive built-in tool.

Bulgarian word lists

The word list feature will generate a frequency list of all words that appear in a text or corpus. A very large corpus can be used to generate a list of all words that exist in Bulgarian or all words that start, contain or end with specific characters. Advanced options can be used to generate lists of grammatical categories or parts of speech used in a corpus together with their frequencies. more»
