Основа слова не обязательно будет совпадать с морфологическим корнем слова. Стеммер - это конкретная реализация алгоритма стемминга. Стемминг используется в поисковых системах, в различных [NLP](https://ru.wikipedia.org/wiki/Обработка_естественного_языка)-задачах и является частью процесса нормализации текста. 8 | 9 | ## Установка 10 | 11 | Установка с помощью pip: 12 | ``` 13 | pip install git+https://github.com/Desklop/Uk_Stemmer 14 | ``` 15 | 16 | Установка из исходных файлов: 17 | ``` 18 | git clone https://github.com/Desklop/Uk_Stemmer 19 | cd Uk_Stemmer 20 | pip install -e . 21 | ``` 22 | 23 | ## Использование 24 | 25 | Стеммер состоит из класса [UkStemmer](https://github.com/Desklop/Uk_Stemmer/blob/master/uk_stemmer/uk_stemmer.py#L32), который содержит метод [stem_word()](https://github.com/Desklop/Uk_Stemmer/blob/master/uk_stemmer/uk_stemmer.py#L69), выполняющий стемминг слова. Данный метод принимает слово в виде строки и возвращает найденную стемму (основу) данного слова так же в виде строки. 26 | 27 | Простой пример для стемминга каждого слова в строке: 28 | ```python 29 | import re 30 | from uk_stemmer import UkStemmer 31 | 32 | stemmer = UkStemmer() 33 | test_string = 'Привіт, як твої справи?
