Persian 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 Persian to easily discover what is typical and frequent in the language and to notice phenomena which would go unnoticed without a large sample of Persian 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 Persian single-word or multi-word expressions of various types can be generated. Even users without any technical knowledge can create their own Persian corpus using the Sketch Engine's intuitive built-in tool.

Tools to work with Persian text corpora

To work with the Persian language, Sketch Engine offers the following tools:

Persian concordance

The concordancer included in Sketch Engine can be used to display a list of examples (called concordance) of the search word or phrase as it appears in Persian language text corpora. The search will display the keyword with some context to the right and context to the left of the keyword (KWIC concordance). more»

Persian 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 Persian 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»

N-grams in Persian

Generating a list of N-grams contained in a text makes it possible to identify and study patterns and notice phenomena related to multi-word units (MWU) in Persian that cannot be detected by other tools. more»
